Technical Field
The application relates to the technical field of film packaging, in particular to a paper film laminating method for film packaging.
Background
When the paper film laminating package is applied to product packaging with a certain height, the film needs to be longer than the paper in the paper film laminating production stage. In the cardboard laminating stage, two ends of the film are adhered to the adhesive area of the cardboard, but the length of the film is larger than that of the cardboard, so that articles can be placed between the film and the cardboard, and the product packaging is realized.
Currently, paper film local lamination in the industry is realized by adopting a film absorption roller to realize equal-length lamination in a ratio of 1:1 of a film to a paperboard. For devices and production processes that achieve unequal length film coatings, e.g., film to paperboard ratios greater than 1:1, one approach adopted in the industry is: the roller assembly with the specific shape realizes the pretreatment of the film, specifically, the roller with the convex part is meshed with the roller with the concave part for transmission, and the irregular film coating between the film and the paper is realized by convex-concave matching by utilizing the convex-concave principle. But the uneven length tectorial membrane is realized with the unsmooth cooperation of two film suction roller, because the protruding height of arch and the depth dimension of recess are fixed, so the length extension of film has the limitation.

In one embodiment, the step of controlling the first adsorption mechanism to adsorb the film includes: detecting the position of the film; and judging whether the film is conveyed to the first adsorption mechanism, if so, controlling the first adsorption mechanism to act and adsorb.
In one embodiment, the film-wrapped paper film laminating apparatus further comprises a slitting mechanism; wherein, before the step of controlling the retraction mechanism to drive the first suction mechanism and/or the second suction mechanism to move based on the size of the cardboard so that the distance between the first suction mechanism and the second suction mechanism matches the size of the cardboard, the method further comprises: and controlling the splitting mechanism to cut off one end of the film close to the film feeding mechanism.
In one embodiment, the step of "providing paperboard" comprises: slitting the paperboard based on the paper film lamination ratio; gluing partial areas of the cut paperboard to form gluing areas; and conveying the glued paperboard.

Referring to fig. 1 and 2, in one embodiment of the present application, a film-wrapped paper film laminating apparatus 100 is provided, the film-wrapped paper film laminating apparatus 100 is used for realizing the lamination of different size ratios between a paper board 101 and a film 102, and the laminated structure (as shown in fig. 6) can be used for the packaging of products, especially products with a certain height.
As shown in fig. 1 and 2, the paper film laminating apparatus 100 provided by the present application includes at least a base 10, a film feeding mechanism 20, a first adsorption mechanism 30, a second adsorption mechanism 40, a film winding mechanism 50, and a retracting mechanism 60; the base 10 serves as a basic carrier member for carrying various mechanisms and components. The film feeding mechanism 20 is used for feeding the film 102; during the continuous conveyance of the film 102 by the film feeding mechanism 20, one end of the film 102 naturally hangs down and moves toward the first adsorption mechanism 30. The first adsorption mechanism 30 is installed on the base 10 for adsorbing the film 102; the second adsorption mechanism 40 is arranged at a distance from the first adsorption mechanism 30 and is used for adsorbing one end of the film 102 close to the film conveying mechanism 20; the retraction mechanism 60 is respectively connected with the first adsorption mechanism 30 and the second adsorption mechanism 40, and respectively drives the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move so as to change the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40, thereby adjusting the length of the film 102 between the first adsorption mechanism 30 and the second adsorption mechanism 40 and realizing the taking of the film 102 with any length; the film rolling mechanism 50 is mounted on the base 10, and at least part of the film rolling mechanism 50 can rotate relative to the base 10, so that the film 102 between the first adsorption mechanism 30 and the second adsorption mechanism 40 is synchronously rolled during the movement of the retraction and release mechanism 60; after the length of the film 102 with a desired length is adjusted by the retracting mechanism 60, at least a portion of each of the first suction mechanism 30 and the second suction mechanism 40 can move relative to the base 10 to respectively drive the film 102 to move toward the paper board 101 and cover the paper board 101, and at the same time, the film winding mechanism 50 releases the wound film 102.
It can be understood that, in the present application, as the film 102 is continuously conveyed (released) by the film conveying mechanism 20, the length of the film 102 is continuously increased, and after the releasing and retracting mechanism 60 continuously drives the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move so that the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is equal to the preset length of the film 102, the first adsorption mechanism 30 and the second adsorption mechanism 40 respectively adsorb the film 102, so as to obtain the film 102 with the required preset length between the first adsorption mechanism 30 and the second adsorption mechanism 40; and by arranging the film rolling mechanism 50, when the retraction mechanism 60 adjusts the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 to adapt to the length of the paper board 101, the film rolling mechanism 50 grabs and rolls the film 102 between the first adsorption mechanism 30 and the second adsorption mechanism 40, so as to avoid the film 102 from being stacked and disordered, at least part of the first adsorption mechanism 30 and the second adsorption mechanism 40 moves relative to the base 10, so as to drive the film 102 to move towards the paper board 101 and cover the paper board 101, and simultaneously the film rolling mechanism 50 releases the rolled film 102, and the released film 102 can be hung or stacked on the paper board 101; in this way, the need for different ratios of the length of the film 102 to the length of the paperboard 101 is achieved.
Wherein, the film roll inevitably has an initial end, namely an initial end 103, when the film is fed, the initial end 103 naturally hangs down and is fed towards one end of the first adsorption mechanism 30, in one embodiment, after the retraction mechanism 60 completes the adjustment of the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40, the first adsorption mechanism 30 preferably adsorbs the initial end 103 of the film, the second adsorption mechanism 40 adsorbs one end of the film close to the film feeding mechanism 20, and cuts the film at the end of the film feeding mechanism 20, so as to obtain a film segment for film coating with a required length, and as the first adsorption mechanism 30 adsorbs the initial end of the film, the film at the end does not need to be cut, thereby simplifying the process. Of course, in other embodiments, the first adsorption mechanism 30 may adsorb other positions of the thin film, and in this case, the excess thin film at the end away from the second adsorption mechanism 40 and outside the adsorption position of the first adsorption mechanism 30 needs to be cut off, so that the obtained thin film is the thin film with the preset length required for coating.
As shown in fig. 1, the film feeding mechanism 20 is suspended from the base 10. The film feeding mechanism 20 may be supported by the base 10 or may be supported by another member having a supporting function. In one embodiment, the film feeding mechanism 20 is located above the base 10 in a direction perpendicular to the base 10. This allows the film feeding mechanism 20 to release the film 102 with a sufficient stroke by vertically lowering the film 102.
In one embodiment, the film feeding mechanism 20 includes a film feeding roller 21 and a film feeding motor (not shown), and the film feeding roller 21 is wound with the film 102 to form a roll of film. The film feeding motor is connected with the film feeding roller 21 and drives the film feeding roller 21 to rotate, so that the film placing or film conveying 102 action is realized. Of course, the type of the film feeding mechanism 20 is not limited to the above-described structure, and other structures having a function of feeding a film may be employed.
As shown in fig. 2, the main function of the first absorbing mechanism 30 is to absorb the starting end 103 of the film 102 and to move the starting end of the film 102 toward the paper board 101 and to realize the combination of the film 102 and the paper board 101. In one embodiment, the first suction mechanism 30 is located between the base 10 and the film feeding mechanism 20 in a direction perpendicular to the base 10, so that the structure of the paper film laminating apparatus 100 is also more compact.
As shown in fig. 2, the first adsorption mechanism 30 includes a first seat 31, a first adsorption plate 32 and a third driving member 33, the first seat 31 is installed on the base 10 and serves as a bearing member; the first adsorption plate 32 is mounted on the first holder 31 and can slide towards the paper board 101 relative to the first holder 31, and the first adsorption plate 32 is used for adsorbing the starting end 103 of the film 102; the third driving member 33 is connected to the first adsorption plate 32 to drive the first adsorption plate 32 toward the paper sheet 101. It will be appreciated that the arrangement here as sliding makes use of the inherent guidance of the sliding structure to make the movement of the first adsorption plate 32 more reliable and smooth; and the sliding mode is simple and low in cost. Here, the sliding structure may be provided as a slide rail and a slider structure. Of course, the movement of the first absorption plate 32 relative to the first seat 31 is not limited to the sliding motion, and it can be provided as a screw rod structure or directly using an air cylinder, etc., without being limited thereto.
In one embodiment, the first adsorption mechanism 30 further includes a sensor (not shown) for sensing the position where the starting end 103 of the film 102 reaches the first adsorption plate 32, and the sensor is in signal connection with the first adsorption plate 32 to control the first adsorption plate 32 to perform the film adsorption action according to the signal sensed by the sensor. Specifically, when the sensor senses that the start end 103 reaches the first adsorption plate 32, the sensor controls the first adsorption plate 32 to start and adsorb the start end 103 of the film 102. The sensor may be a touch sensor, a proximity sensor, or the like capable of sensing the position of an object. For example, the sensor is provided as a photoelectric sensor, a hall element, an electromagnetic sensor, a travel switch, or the like. In the present embodiment, the sensor is a photosensor; when the start end 103 shields the sensor, it indicates that the start end 103 of the film 102 reaches the first adsorption plate 32. In addition, in the present embodiment, the sensor is disposed on the first adsorption plate 32 and between the first adsorption plate 32 and the film 102, but of course, the sensor may be disposed near the lower surface of the first adsorption plate 32 so as to accurately identify whether the starting end 103 of the film 102 reaches the first adsorption plate 32.
In the present application, the first housing 31 may be integrated with the base 10 or separated from the base. The base 10 is more stable and reliable as a whole due to the integral structure. And the split type structure can also facilitate the processing of the base 10 and the first seat 31. In this embodiment, the first seat 31 may be provided separately from the base 10.
As shown in fig. 2, a first groove 311 is formed on a surface of the first receiving body 31 facing the base 10, and a cavity is defined between the first groove 311 and the base 10 after the first receiving body 31 is mounted on the base 10. The first suction pad 32 is received in a chamber and the chamber is arranged to pass through in the direction of movement of the first suction pad 32, so that the first suction pad 32 is extended out of the chamber by the third driving member 33 and moved towards the sheet 101.
Referring to fig. 2, the first adsorption plate 32 is provided in a box shape, a plurality of first adsorption holes 321 are opened on a side of the first adsorption plate 32 facing the paper board 101, and an adsorption member is provided in the first adsorption plate 32. The adsorption member is an air pump or a vacuum pump, and after the adsorption member is started, air is continuously sucked into the first adsorption plate 32 through the first adsorption holes 321, so that negative pressure is formed in the first adsorption plate 32 relative to the outside of the first adsorption plate 32, and the film 102 is adsorbed on the first adsorption plate 32.
As shown in fig. 2, the second adsorption mechanism 40 mainly functions to adsorb one end of the film 102 close to the film feeding mechanism 20 and drive the film to move toward the paper board 101, so that the film 102 and the paper board 101 are combined. The second adsorption mechanism 40 is located above the first adsorption mechanism 30 in a direction perpendicular to the susceptor 10; meanwhile, the second adsorption mechanism 40 is located between the first adsorption mechanism 30 and the film feeding mechanism 20. In this way, the film feeding mechanism 20, the second suction mechanism 40, and the first suction mechanism 30 are sequentially arranged in a direction perpendicular to the base 10, so that the structure of the paper film laminating apparatus 100 is more compact. And, the distance between the second adsorption mechanism 40 and the first adsorption mechanism 30 corresponds to the distance between the glue coated areas of both ends of the paper sheet 101. Therefore, when the second adsorption mechanism 40 drives the film 102 to move towards the paper board 101, the film 102 and the paper board 101 can be correspondingly combined.
Specifically, in one embodiment, as shown in fig. 2, the second suction mechanism 40 includes a second seat 41, a second suction plate 42, and a fourth driving member 43. The second seat 41 is used as a carrier, and is disposed in a floating manner relative to the first adsorption mechanism 30, that is, the second seat 41 and the first adsorption mechanism 30 are spaced apart from each other. The second absorption plate 42 is slidably mounted on the second seat 41 for absorbing one end of the film 102 close to the film feeding mechanism 20; the fourth driving member 43 is provided as a motor or a cylinder. The fourth driving member 43 is connected to the second absorption plate 42 for driving the second absorption plate 42 to slide on the second base 41 and move toward the paper board 101, so as to drive one end of the film 102 close to the film feeding mechanism 20 to cover the paper board. It is understood that, provided herein as a slide, guidance of the slide structure itself can be utilized to make the movement of the second adsorption plate 42 more reliable; and the sliding mode is simple and the cost is low. Here, the sliding structure may be provided as a slide rail and slider structure. Of course, the movement of the second suction plate 42 relative to the second seat 41 is not limited to the above-mentioned sliding, and it may be set as a screw rod structure or directly adopt an air cylinder, etc., and is not limited herein.
As shown in fig. 2, the second seat 41 is spaced apart from the first seat 31 in a direction perpendicular to the base 10. The surface of the second fastening structure 41 away from the base 10 is provided with a second slot 411, after the second fastening structure 41 is mounted on the base 10 or other load-bearing components. The second suction plate 42 is installed in the second recess 411, and the second recess 411 is provided to be penetrated in a direction in which the second suction plate 42 moves, so that the second suction plate 42 is protruded and moved toward the sheet 101 by the fourth driving member 43.
As shown in fig. 2, the second suction plate 42 is provided in a box shape, a plurality of second suction holes 421 are opened on a side of the second suction plate 42 facing the paper sheet 101, and a suction member is provided in the second suction plate 42. The adsorption member adopts an air pump or a vacuum pump, and after the adsorption member is started, air is continuously sucked into the second adsorption plate 42 through the second adsorption hole 421, so that negative pressure is formed inside the second adsorption plate 42 relative to the outside of the second adsorption plate 42, and the film 102 is adsorbed on the second adsorption plate 42.
As shown in fig. 2, the film winding mechanism 50 is rotatably mounted on the base 10 and is located between the base 10 and the film feeding mechanism 20. The film winding mechanism 50 is mainly used for winding the film 102, and prevents the film 102 from being accumulated between the first adsorption mechanism 30 and the second adsorption mechanism 40 when the distance therebetween is shortened, thereby preventing the film from being coated. Therefore, when the retraction mechanism 60 drives the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move so that the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is shortened, the film rolling mechanism 50 rolls the film synchronously, the middle part of the film 102 between the first adsorption mechanism 30 and the second adsorption mechanism 40 is kept to have a certain tension relative to the starting end 103 and the end close to the film conveying mechanism 20, and the film 102 is prevented from being stacked, even twisted and wound, and the like.
Wherein, as shown in fig. 2, the film winding mechanism 50 can rotate around the horizontal axis, i.e. the film winding mechanism 50 can realize horizontal film winding to prevent the film 102 from winding or stacking, etc.
In one embodiment, as shown in fig. 2, the film winding mechanism 50 is disposed between the base 10 and the second adsorption mechanism 40. Specifically, the film winding mechanism 50 is disposed between the first adsorption mechanism 30 and the second adsorption mechanism 40 in a direction perpendicular to the base 10, so that the base 10, the first adsorption mechanism 30, the film winding mechanism 50, and the second adsorption mechanism 40 are disposed in order in the direction perpendicular to the base 10. Therefore, the structure of the paper film laminating equipment is more compact. When the film 102 is completely laminated with the paper sheet 101, the film winding mechanism 50 releases the wound film 102.
In the present embodiment, as shown in fig. 2, the film winding mechanism 50 is mounted on the first adsorption mechanism 30. Specifically, the film winding mechanism 50 is mounted on the first seat 31 and is located on a side of the first seat 31 close to the film 102, so that the film winding mechanism 50 winds the film 102. Of course, in other embodiments, the position where the film winding mechanism 50 is disposed is not limited to the above or shown in the drawings. For example, when the film winding mechanism 50 is provided at the midpoint between the first suction mechanism 30 and the second suction mechanism 40, and when the distance between the second suction mechanism 40 and the first suction mechanism 30 is changed, for example, the film winding mechanism 50 can change its position with the change of the distance so that the film winding mechanism 50 is always located at the midpoint between the first suction mechanism 30 and the second suction mechanism 40 when winding the film.
Referring to fig. 2, the film winding mechanism 50 includes a second driving member 51, a first rotating member 52, and a grasping member (not shown). The second driver 51 may be provided as a motor or other power unit. The first rotating member 52 is rotatably mounted on the base 10 and is driven by the second driving member 51 to roll up or release the film 102. The grasping member is disposed on the first rotating member 52 and is used for grasping the film (or the film between the base 10 and the second adsorption mechanism 40) between the first adsorption mechanism 30 and the second adsorption mechanism 40, so that the first rotating member 52 can roll up the film 102 during the rotation process.
In one embodiment, as shown in fig. 4, the first rotating member 52 is a roller and the roller is provided with a through hole (not shown) communicating with the inside of the roller; the grabbing piece is arranged as an adsorption piece which can generate adsorption force through the through hole so as to adsorb the film 102 to the outer surface of the roller. With this arrangement, the gripping member and the first rotating member 52 can be integrally formed to further facilitate the rolling of the film 102 by the first rotating member 52. Here, the absorption piece adopts aspiration pump or vacuum pump, and absorption piece starts the back and constantly inhales the roller with the air through the through-hole inside, makes the inside relative roller of roller outside form the negative pressure to adsorb film 102 in the roller. Of course, the roller and the suction member may be provided with the same member, such as a vacuum suction roller or the like.
In one embodiment, the first rotating member 52 is preferably disposed at a midpoint between the first suction mechanism 30 and the second suction mechanism 40, so that when the retraction mechanism 60 is adjusted to make the distance between the first suction mechanism 30 and the second suction mechanism 40 equal to the preset desired length of the film 102 and drive the film 102 toward the paper board 101 for covering, the first rotating member 52 can suck and retract the film 102 from the middle of the length of the film 102, so as to equalize the force and keep the tension at the two ends of the film 102 and prevent the loose accumulation of the film 102. Wherein the first rotating member 52 is movable in the vertical direction so that the first rotating member 52 can adjust its position according to the different preset lengths of the films 102 so that the first rotating member 52 is always located at the midpoint position between the first adsorption mechanism 30 and the second adsorption mechanism 40 at the start of the film winding.
Further, as shown in fig. 2, the film winding mechanism 50 further includes a third seat 53, the third seat 53 is mounted on the first seat 31, the first rotating member 52 is rotatably mounted on the third seat 53, and the second driving member 51 is also mounted on the third seat 53 and connected to the first rotating member 52.
As shown in fig. 2 and 3, it can be understood that the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is a size (width or length) corresponding to the paper sheet 101, and different distances between the first adsorption mechanism 30 and the second adsorption mechanism 40 can be adapted to paper sheets 101 of different sizes. Therefore, the paper film laminating device provided by the application can realize the lamination between the films 102 with different sizes and the paper boards 101 with different sizes by arranging the retracting mechanism 60 to realize the adjustment of the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40, so as to adjust the size of the films 102 required by the laminating and adjust the paper film laminating device to be suitable for the paper boards 101 with different lengths. In other words, the production requirements for the lamination between the paperboard 101 and the film 102 in any proportion can be realized.
As shown in fig. 1 to 3, the retracting mechanism 60 is located between the first suction mechanism 30 and the second suction mechanism 40 along the vertical direction, so that the overall structural layout of the paper film laminating apparatus 100 is more compact and space-saving. Of course, in other embodiments, the position where the retraction and release mechanism 60 is disposed is not limited, and it is only necessary to be able to drive the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move relatively to adjust the distance therebetween.
Further, the retraction mechanism 60 may only drive the second adsorption mechanism 40 to move relative to the first adsorption mechanism 30, so as to adjust the distance between the second adsorption mechanism 40 and the first adsorption mechanism 30; of course, the retraction and release mechanism 60 may only drive the first adsorption mechanism 30 to move relative to the second adsorption mechanism 40, and the distance between the second adsorption mechanism 40 and the first adsorption mechanism 30 can be adjusted as well. Still alternatively, the retracting mechanism 60 can drive the second suction mechanism 40 and the first suction mechanism 30 to move at the same time, so as to adjust the distance between the second suction mechanism 40 and the first suction mechanism 30.
In one embodiment, the retraction mechanism 60 only moves the second suction mechanism 40 or the first suction mechanism 30, so as to adjust the distance between the second suction mechanism 40 and the first suction mechanism 30, thereby controlling the length of the film 102 for laminating.
In this embodiment, the moving speed V1 of the first adsorption plate 32 or the second adsorption plate 42, the rotating speed n of the film taken up by the first rotating member 52, and the relationship between the rotating speed n and V1 is:
where k is a correction factor and r is the diameter of the first rotating member 52.
In another embodiment, the retraction mechanism 60 can move the first suction plate 32 and the second suction plateThe attachment plate 42 moves simultaneously. The moving speed V1 of the first absorbing plate 32 or the second absorbing plate 42, the rotating speed at which the first rotating member 52 winds up the film, is n, and the relationship between the rotating speed n and V1 is:
where k is a correction factor and r is the diameter of the first rotating member 52.
In one embodiment, the pick and place mechanism 60 may be configured as an automatic pick and place mechanism or a manual pick and place mechanism. The automatic retraction and release mechanism can automatically adjust the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40. The manual retraction and release mechanism requires manual work to adjust the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40. It is understood that the specific choice of the pick and place mechanism 60 can be made according to actual production or operational requirements and is not limited thereto. In this embodiment, the pick-and-place mechanism 60 is configured as an automatic pick-and-place mechanism to provide a basis for an automatic laminating line between the sheets 101 and the film 102.
In one embodiment, as shown in fig. 1 and 3, the retraction mechanism 60 includes at least a telescoping unit 61 and a first driving member 64; the telescopic unit 61 is arranged between the first adsorption mechanism 30 and the second adsorption mechanism 40 and is respectively connected with the first adsorption mechanism 30 and the second adsorption mechanism 40; the first driving member 64 is connected to the telescopic unit 61 and configured to drive the telescopic unit 61 to perform telescopic motion, so as to drive the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move, so as to adjust a distance between the first adsorption mechanism 30 and the second adsorption mechanism 40, so that the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is equal to a preset length of a required film, and when the film is to be coated, the telescopic unit 61 is driven to move to drive the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move in an opposite direction, so that the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is equal to the length of the paper board 101 to be coated.
Further, the telescopic unit 61 may be provided in a telescopic rod unit, a link unit, or the like. For example, as shown in fig. 3, in the present embodiment, the telescopic unit 61 is provided as a link unit. The link units are respectively connected to the first adsorption mechanism 30 and the second adsorption mechanism 40, and the link units make the link units perform extension or retraction movement under the action of tension or compression of the first driving member 64, so as to drive the second adsorption mechanism 40 to move relative to the first adsorption mechanism 30. Here, the link unit includes a plurality of links hingedly connected to each other. The mutual rotation between the connecting rods can realize the extension or retraction movement. Specifically, a plurality of mutually hinged connecting rods are connected to form a parallelogram, and the first adsorption mechanism 30 and the second adsorption mechanism 40 are connected with two opposite hinged points of the parallelogram, so that the stability of movement is improved.
As shown in fig. 1 or fig. 3, the retraction mechanism 60 further includes a first mounting plate 62 and a second mounting plate 63, and the first mounting plate 62 and the second mounting plate 63 are disposed at intervals; the first adsorption mechanism 30 is mounted on the base 10 through the first mounting plate 62, and the second adsorption mechanism 40 is mounted on the second mounting plate 63; the telescopic unit 61 is disposed between the first mounting plate 62 and the second mounting plate 63, and is connected to the first mounting plate 62 and the second mounting plate 63, respectively. So set up, the area of contact of first adsorption device 30 with first mounting panel 62 has been increased, the area of contact of second adsorption device 40 with second mounting panel 63 has been increased, and the area of contact of flexible unit 61 with first mounting panel 62 and second mounting panel 63 has still been increased, thereby when flexible unit 61 applys thrust to corresponding first adsorption device 30 and second adsorption device 40 respectively through first mounting panel 62 and second mounting panel 63, through first mounting panel 62 and second mounting panel 63 dispersed thrust, make first adsorption device 30 and second adsorption device 40 atress even, the motion is stable.
As shown in fig. 1, the paper film laminating apparatus 100 further includes a paper board conveying mechanism 70, and the paper board conveying mechanism 70 is disposed at one side of the base 10 to convey the paper board 101 to a predetermined station to perform lamination with the film 102 at the predetermined station.
In one embodiment, the paper board conveying mechanism 70 is provided with a conveyor belt structure, and the paper boards 101 are placed on the conveyor belt 71 and conveyed forward by the conveyor belt 71. Of course, the cardboard conveying mechanism 70 is not limited to the structure of the conveying belt, and it may be configured to realize other structures for conveying the cardboard (material).
Further, before the paper board 101 is conveyed to a predetermined station, the paper board 101 needs to be subjected to glue coating treatment, so that when the paper board 101 is conveyed to the predetermined station, the first adsorption mechanism 30 and the second adsorption mechanism 40 respectively drive the two ends of the film 102 to be bonded on the paper board 101, that is, the combination between the paper board 101 and the film 102 is realized.
Here, the principle of the cylinder transfer printing is used for the cardboard gluing, glue is transferred to the cardboard 101 through the glue strip on the gluing cylinder (not shown), only the glue strip (including length and/or width) suitable for the size of the cardboard 101 needs to be attached to the gluing cylinder, the glue strip is glued through the glue groove during the rotation of the gluing cylinder, so that partial coating of the glue can be realized, the cardboard 101 is provided with glue for realizing partial combination of the film 102 and the cardboard 101, and the part of the cardboard 101 without glue is separated from the film 102. The lamination of the paper board 101 and the film 102 means that after the paper board 101 is glued, the paper board is continuously conveyed by the paper board conveying mechanism 70, when the paper board 101 is conveyed to a preset station, the first adsorption mechanism 30 and the second adsorption mechanism 40 respectively drive the two ends of the film 102 to be bonded to the gluing area of the paper board 101, and at this time, the film rolling mechanism 50 also finishes the release of the rolled film (the part is not bonded with the glue), namely, the structure shown in fig. 6 and 7 is presented.
As shown in fig. 1 or fig. 2, the paper film laminating apparatus 100 may further include a dividing mechanism 80, wherein after the retracting mechanism 60 drives the first suction mechanism 30 and/or the second suction mechanism 40 to move so that the distance therebetween is equal to the predetermined required length of the film 102, the dividing mechanism 80 is used to cut the film 102, so that the first suction mechanism 30 and the second suction mechanism 40 can drive and move the cut film 102 to be laminated with the paper board 101, and further, the film 102 is laminated on the paper board 101. It will be appreciated that by providing the slitting mechanism 80, it is possible to slit the film 102 according to the desired length of the film 102, so that the lamination of different proportions of the cardboard 101 and the film 102 can be precisely met in real time according to actual needs.
In one embodiment, the slitting mechanism 80 is disposed between the sheet transport mechanism 70 and the base 10; the slitting mechanism 80 is located between the film feeding mechanism 20 and the second suction mechanism 40 in a direction perpendicular to the base 10.
Specifically, the slitting mechanism 80 includes a slitting blade 81 and a corresponding driving member (not shown), which is connected to the slitting blade 81 and can drive the slitting blade 81 to move relative to the second suction mechanism 40 to cut the film 102 at a suitable position.
The process of laminating the paper sheet 101 and the film 102 according to the present invention will be described with reference to the drawings.
As shown in fig. 1 and 5, the lamination process between the paper board 101 and the film 102 is as follows: the paper board cutting, paper board gluing, paper conveying and feeding, the film feeding mechanism 20 for film feeding, the first adsorption mechanism 30 for film adsorption, the film laminating length adjustment, the second adsorption mechanism 40 for film adsorption, the film cutting, and the film folding and unfolding mechanism 60 for film folding and unfolding, wherein the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is equal to the length between two gluing areas on the paper board 101, and the film rolling mechanism for film rolling and paper film folding. The paperboard slitting refers to slitting the paper or paperboard 101 into sheets of required sizes. The gluing of the paperboard refers to the gluing treatment in the gluing area of the paperboard 101. The sheet feeding plate is a sheet feeding plate 101 fed by the sheet feeding mechanism 70. The film feeding mechanism 20 feeds the film 102 by the film feeding mechanism 20. The first adsorption mechanism adsorbs the thin film means that the first adsorption mechanism 30 adsorbs the starting end 103 of the thin film 102 (the end of the thin film 102 close to the susceptor 10).
The step of adjusting the length of the film comprises the following steps: the film feeding mechanism 20 feeds the film 102, and the retraction and release mechanism 60 adjusts the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 to be equal to the preset required length of the film 102, namely, the adjustment of the length of the film 102 is realized. The retracting mechanism 60 adjusts the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 to be equal to the length between two glue coating areas on the paper board 101, so that the first adsorption mechanism 30 and the second adsorption mechanism 40 correspond to the two glue coating areas of the paper board 101, and thus the two ends of the slit film 102 can be covered at the glue coating areas. The film winding mechanism 50 is configured to wind the film 102 by the film winding mechanism 50, and the film winding mechanism 50 simultaneously winds the film when the first suction mechanism 30 and the second suction mechanism 40 move toward each other to adjust the distance therebetween to the length of the paper sheet 101. When the first adsorption mechanism 30 and the second adsorption mechanism 40 respectively drive the two ends of the film 102 to move towards the paper board 101, the film rolling mechanism 50 releases the film 102 rolled by the film rolling mechanism. The second suction means sucks the film 102 at the end of the film 102 close to the film feeding means 20 by the second suction means 40. Slitting the film is performed by slitting the film 102 using slitting mechanism 80. Paper lamination refers to laminating the paper sheet 101 and a film member.
Specifically, the paper sheets 101 are slit and the slit paper sheets 101 are glued, and then the glued paper sheets 101 are placed at intervals on the paper sheet conveying mechanism 70 and conveyed to a predetermined position. Meanwhile, the film feeding mechanism 20 feeds the film 102, the starting end 103 of the film 102 is adsorbed by the first adsorption mechanism 30, at this time, the film feeding mechanism 20 continues to feed the film, and the retraction and release mechanism 60 drives the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move so as to enlarge the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 until the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is equal to the preset required length of the film 102, and then the second adsorption mechanism 40 adsorbs the film 102, so that the length adjustment of the film 102 is completed. After the second suction mechanism 40 sucks the film 102, the slitting mechanism 80 is controlled to cut the film 102. After that, the retracting mechanism 60 drives the first adsorption mechanism 30 and/or the second adsorption mechanism 40 again so that the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is equal to the distance between two glue spreading areas on the paper sheet 101, and at the same time, the film winding mechanism 50 grabs or acquires the film between the first adsorption mechanism 30 and the second adsorption mechanism 40 and winds the film. After the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is equal to the distance between two glue coating areas on the paper board 101, the first adsorption mechanism 30 drives the starting end 103 of the film, the second adsorption mechanism 40 drives one end of the film 102 close to the film feeding mechanism 20 to move towards the direction of the paper board conveying mechanism 70, the film winding mechanism 50 simultaneously releases the film 102, the two ends of the film 102 are bonded with the glue coating area on the paper board 101 at a preset position, and after bonding, the first adsorption mechanism 30 and the second adsorption mechanism 40 release the end of the adsorbed film 102, so that the coating between the film 102 and the paper board 101 is completed, and the paper film coated product shown in fig. 6 and 7 is obtained. As shown in fig. 7, the two ends of the slit film 102 are bonded and combined with the glue coating areas (usually, the two ends along the length direction of the paper board 101) on the paper board 101, wherein the ratio of the length of the film 102 to the length of the paper board 101 is greater than 1, and the length of the film 102 can be arbitrarily increased by the present application, so as to be suitable for the packaging of products with different specifications.
As shown in fig. 8-10, both ends of the film 102 are laminated with the paperboard 101 to form a carrier that can be used to package a product. As shown in fig. 8, the product 200 to be packaged is placed in the space enclosed by the film 102 and the corresponding paper or paperboard 101, and the larger the length of the film 102 (i.e., the dimension of the film in the second direction in fig. 7) is, the higher the height of the product 200 (i.e., the dimension in the first direction) can be adapted to. It is clear that in the second direction in fig. 8, the length of the film 102 after it has been laid flat is greater than the length of the sheet 101. After the product to be packaged is placed in the space formed by the film 102 and the paper board 101 in an enclosing mode, the paper board 101 is turned over, the film is attached to the product 200, the product 200 is limited by the film, and the product is placed to move or move out of the packaging space.
As shown in fig. 7 to 10, the position where the film 102 is bonded to the paper board 101 is a folded portion of the paper board 101, and the paper board 101 is used for carrying the product 200.
As shown in fig. 11, in an embodiment, the present application further provides a paper film laminating method for film packaging, which is applied to the paper film laminating apparatus 100 described above, i.e., implemented based on the paper film laminating apparatus 100. The specific structure of the paper film laminating apparatus 100 can be referred to in the preamble, and will not be repeated here. Specifically, the paper film laminating method for the film package comprises the following steps:
s10: providing a paperboard 101;
s20: controlling the film feeding mechanism 20 to feed the film 102;
s30: controlling the retraction and release mechanism 60 to drive the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move based on the preset length of the film 102 required by film covering, so that the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is equal to the preset length of the film 102;
s40: controlling the first adsorption mechanism 30 to adsorb the film 102; preferably, the first adsorption mechanism 30 adsorbs the starting end 103 of the film roll;
s50: controlling the second adsorption mechanism 40 to adsorb one end of the film 102 close to the film feeding mechanism 20;
s60: controlling the retraction mechanism 60 to drive the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move based on the size of the paper sheet 101, so that the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 matches the size of the paper sheet 101;
s70: controlling the film rolling mechanism 50 to rotate so as to roll up the film 102 positioned between the first adsorption mechanism 30 and the second adsorption mechanism 40;
s80: controlling the first adsorption mechanism 30 and the second adsorption mechanism 40 to respectively drive the adsorbed film 102 to move towards the paper board 101, and enabling the adsorbed film 102 to be covered on the paper board 101; wherein, when the first adsorption mechanism 30 and the second adsorption mechanism 40 drive the film 102 to move, the film winding mechanism 50 rotates therewith and releases the wound film 102. Preferably, the first adsorption mechanism 30 drives the corresponding start end 103 to move, and the second adsorption mechanism 40 drives one end of the film close to the film feeding mechanism 20 to move, so that two ends of the film 102 are correspondingly covered on the paper board 101, and the middle part of the film 102 is prevented from being covered with the paper board 101. Of course, the first adsorption mechanism 30 may adsorb other positions of the film 102 in other embodiments.
It can be understood that the retraction mechanism 60 drives the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move, so as to change the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40, and further adjust the length of the film 102 located between the first adsorption mechanism 30 and the second adsorption mechanism 40, so as to achieve the selection of the preset length of the film 102, and the retraction mechanism 60 can also adjust the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 to adapt to the length of the paper board 101, so that the paper film laminating device 100 is suitable for paper boards 101 of different specifications, and thus, the laminating requirements of different proportions of the length of the film 102 and the length of the paper board 101 are achieved.
There is no precedence between step S10 and step S20. Step S10 may be performed first, or step S20 may be performed first; or step S10 and step S20 are performed simultaneously. In the present embodiment, step S10 and step S20 are performed simultaneously. Step S30 may be performed first, or step S40 may be performed first, without any order between step S30 and step S40.
In one embodiment, step S70 includes the following steps:
s71: controlling the film rolling mechanism 50 to adsorb the thin film 102 positioned between the first adsorption mechanism 30 and the second adsorption mechanism 40;
s72: the film winding mechanism 50 is controlled to rotate and wind up the released film 102. In this way, the film winding mechanism 50 winds the loosened film 102, so that the two ends of the film 102 are tensioned, and the film 102 is prevented from being stacked or wound to affect film covering when the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 is shortened.
In the present embodiment, as shown in fig. 2, the film winding mechanism 50 rotates about a horizontal axis to wind up the unwound film 102. The film winding mechanism 50 rotates around a horizontal axis to realize smooth film winding and prevent the film 102 from twisting.
Preferably, the film winding mechanism 50 starts to wind the film from a midpoint position between the first adsorption mechanism 30 and the second adsorption mechanism 40, so that the tension of the two ends of the film 102 is uniform, a certain tension is maintained at the two ends of the film 102, and the film 102 is prevented from being accumulated due to a long length of the film 102 at one end.
In one embodiment, step S60 and step S70 are performed simultaneously, and the retracting mechanism 60 adjusts the distance between the first suction mechanism 30 and the second suction mechanism 40 to be shorter to fit the size of the paper sheet 101, so that the film is wound up simultaneously, and the film 102 is prevented from being stacked up in order.
When the retraction mechanism 60 drives the first adsorption mechanism 30 and/or the second adsorption mechanism 40 to move, the length of the released film 102 is S1, and S1 indicates the difference between the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 at the beginning and the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40 after the first adsorption mechanism 30 and the second adsorption mechanism 40 move to adapt to the paper board 101; the length of the film 102 wound by the film winding mechanism 50 is S2; wherein S1= S2.
In one embodiment, step S40 includes:
s41: detecting the position of the film;
s42: whether the film 102 is conveyed to the first adsorption mechanism 30 is judged, and if so, the first adsorption mechanism 30 is controlled to operate and adsorb. Preferably, the start end 103 of the film roll is used as the start of the film segment to be coated, so that the first adsorption mechanism 30 adsorbs the start end 103 of the film 102, and therefore, the position of the film start end 103 is detected at the time of the golden process, and whether the film start end 103 is conveyed to the first adsorption mechanism 30 is judged, and if so, the first adsorption mechanism is controlled to adsorb the start end 103.
In one embodiment, before step S60, the paper film laminating method further includes the steps of: s90: the control of the slitting mechanism 80 cuts the end of the film 102 close to the feeding mechanism 20, so that step S80 can be executed.
In one embodiment, step S10 includes:
