The bag pushing mechanism 2 is arranged on the upper side of the bag forming mold core 3, and an executing part of the bag pushing mechanism 2 can move along the cavity channel 301 towards the direction of the discharge hole so as to push materials into the packaging bag 7 after the packaging bag 7 is filled;

The transverse sealing and shearing mechanism 104 is arranged below the discharge port of the bag forming mold core 3, after the packaging bag 7 is filled, the packaging bag 7 filled below and the film not filled above are divided, and the top of the packaging bag 7 below and the bottom of the film above are sealed at the same time;

The film feeding mechanism 102 is used for feeding the film downwards along the center line of the bag-forming mold core 3, and feeding the length of one package 7 at a time, wherein the length of one package 7 refers to the length of the film required for manufacturing one package 7.

The film feeding mechanism 102, the vertical sealing mechanism 103, the horizontal sealing shearing mechanism 104 and the former 101 mentioned below together constitute a bag making mechanism 1.

The cavity of the inclined bagging mold core 3 is used as a material 611 channel, and has double functions of guiding and restraining the light flaky material 611; the lower outlet of the light sheet material 611 is covered by the packaging bag 7, and the light sheet material 611 can slide into the packaging bag 7 along the inclined cavity channel 301 under the action of self gravity; the cavity of the bag-forming mold core 3 can restrict the light material 611 so as to avoid the situation that the material 611 is fluffy and becomes large before entering the packaging bag 7 and is difficult to enter the bag, and the probability that the material 611 is exposed after entering the packaging bag 7 is reduced to a certain extent.

After the material 611 enters the packaging bag 7, the bag pushing mechanism 2 is started to push the material 611 in the packaging bag 7 downwards through the cavity channel 301, so that the possibility of exposing the material 611 is avoided. Finally, the top of the packaging bag 7 is sealed by a transverse sealing and shearing mechanism 104.

After the division is completed, the film feeding mechanism 102 drives the film to be transported downwards along the center line of the bag forming mold core 3, and after the length of one packaging bag 7 is transported, the transportation is stopped, and the next process of bag making and material filling is performed.

The film length of the film below the bag forming mold core 3 is greater than or equal to the length of one film when the film feeding mechanism 102 drives the film to transport one packaging bag 7, so that the transverse sealing and shearing mechanism 104 can finish edge sealing and shearing work, and the bag forming mold core 3 is prevented from interfering.

The device is suitable for packaging the light flaky materials 611 easy to be fluffy, can prevent the materials 611 falling into the packaging bag 7 from being exposed, and is convenient for sealing the packaging bag 7.

As shown in fig. 4 and 5, the specific edge sealing process of the longitudinal sealing mechanism 103 is as follows: the longitudinal sealing mechanism 103 is arranged at one side of the bag-forming mold core 3, and two first heat sealing blocks 1031 are arranged, wherein the first heat sealing blocks are 4-5mm away from the surface of the bag-forming mold core 3, and the first heat sealing blocks 1031 are heated by heating pipes 1033.

One first heat-sealing block 1031 is fixed, and the other first heat-sealing block 1031 is a movable part and is indirectly connected with the first pressing cylinder 1032 through a mounting plate to perform intermittent motion (the film feeding mechanism 102 feeds one bag length and reciprocates once). The film is formed by the forming device 101 and then is folded to form a vertical edge which is coated on the bag forming mold core 3, the folded vertical edge passes through the middle of the two first heat sealing blocks 1031, the piston rod of the first pressing cylinder 1032 extends out, the movable first heat sealing block 1031 moves to be in surface contact with the fixed first heat sealing block 1031, the folded vertical edge is pressed together to realize edge sealing, the piston rod of the first pressing cylinder 1032 is pulled back, the two first heat sealing blocks 1031 are separated and separated from the sealed film, and the edge sealing action is completed once.

As shown in fig. 6 and 7, the specific edge sealing process of the cross seal shear mechanism 104 is as follows: the transverse sealing shearing mechanism 104 is arranged below the bag forming mold core 3 and the longitudinal sealing mechanism 103, two second heat sealing blocks 1041 are arranged, a certain distance is reserved between the heat sealing surfaces of the two second heat sealing blocks 1041, a semi-closed film bag passing through the bag forming mold core 3 passes through the heat sealing surfaces of the two second heat sealing blocks 1041, and the second heat sealing blocks 1041 are heated by a heating rod 1043.

The two second heat-seal blocks 1041 are both indirectly connected to the second pressing cylinder 1042 and perform intermittent movement (the film feeding mechanism 102 feeds one bag length and reciprocates once). A groove is formed in the heat cover of the second heat sealing block 1041 at one side, a cutting blade 1044 is arranged in the groove, the cutting blade 1044 is fixed on a blade mounting rod 1045, the cutting blade 1044 is fixed relative to a movable seat 1047, and the second heat sealing block 1041 has a certain floating amount relative to the movable seat 1047 under the assistance of a compression spring 1046 and a guide rod, so that the cutting blade 1044 protrudes out of the heat cover of the second heat sealing block 1041.

The heat cover of the second heat sealing block 1041 on the other side has a groove, which is a recess for avoiding the cutting blade. During normal operation, the film feeding mechanism 102 feeds a bag length, after the material is filled, the piston rod of the second pressing cylinder 1042 extends out, the two second heat sealing blocks 1041 move, the two heat sealing surfaces are contacted, the fed square tubular film bags are pressed together, edge sealing is achieved, in the sealing process, along with the extending out of the piston rod of the second pressing cylinder 1042, the cutting blade 1044 gradually rises above the heat sealing surface of the second heat sealing block 1041, the film bags are cut off, and sealing of the discharging bags and sealing of the prefilled material bags are achieved.

As shown in fig. 8 and 9, the film feeding mechanism 102 includes a servo motor 1021, a plum coupling 1022, a driving pulley 1023 and a driven pulley 1024 in the power transmission sequence, the driving pulley 1023 and the driven pulley 1024 are connected to the frame 1025 through a shaft, the two pulleys are sleeved with synchronous belts 1026, the above structure is symmetrically provided with two groups, the frames 1025 on both sides can be driven to approach each other along the guide rod 1028 through a cylinder 1027, that is, the two synchronous belts 1026 approach each other, so that the two synchronous belts 1026 clamp the film, and the synchronous belts 1026 are driven to rotate by the servo motor 1021 to feed the film.

Further, the bag forming mold core 3 can be configured into a square cylinder shape, and the outer wall of the bag forming mold core 3 is provided with an exhaust hole, so that when the fluffy material 611 slides down in the cavity, the air in the downstream is discharged too slowly, and the material 611 is difficult to slide down.

Further, as shown in fig. 12 and 13, the bag pushing mechanism 2 comprises a pushing head 201 and a cylinder 202, wherein the pushing head 201 is fixedly connected to the end of a piston rod of the cylinder 202, and the pushing head 201 is arranged centrally relative to the inner wall of the bag forming mold core 3 so as to avoid the pushing head 201 touching the inner wall of the bag forming mold core 3; the air cylinder 202 is capable of driving the push head 201 to push the material 611 through the cavity of the bagging mold core 3.

Further, in order to better restrict the movement path of the push head 201, the bag pushing mechanism 2 further includes a guide slide bar 203 slidably fitted with a linear bearing on the base, and one end of the guide slide bar 203 is connected to the push head 201 to restrict the movement path of the push head 201.

When the push head 201 is driven to linearly move by the telescopic driving of the air cylinder 202, the guide slide bar 203 moves synchronously while the push head 201 moves, and the clearance fit between the guide slide bar 203 and the hole on the base can strengthen the control on the moving path of the push head 201, so that the push head 201 moves strictly according to a preset linear path.

Further, the vertical-inclined automatic bag making and packaging equipment also comprises a film rolling supporting mechanism 4 and a film releasing mechanism 5; the film releasing mechanism 5 is used for pulling the film roll on the film rolling supporting mechanism 4 to convey the film to the bag making mechanism 1.

Further, as shown in fig. 10, the roll film supporting mechanism 4 includes: a support shaft 401 mounted on a bearing support 402 for carrying the film roll; damping means 403 for providing damping to the support shaft 401, capable of tensioning the membrane; a material detection sensor 404 for monitoring the usage state of the film in real time.

By arranging the damping device 403 to provide proper resistance for the rotation of the supporting rotating shaft 401, the film can have effective tensioning force, so that stable film release and accurate film feeding position are ensured; the film roll is prevented from being pulled off by the film releasing mechanism 5, and the film is prevented from being loosened due to excessive rotation of the released film due to factors such as rotation inertia.

The damping device 403 can adopt a semi-automatic pneumatic damping device 403, and the material detection sensor 404 can detect the film residual quantity on the film roll, timely remind of changing the film roll, and simultaneously monitor the film feeding state, and timely alarm when loosening dislocation occurs.

Further, as shown in fig. 11, the film feeding mechanism 5 includes a pressing force adjusting device 501, a film feeding driving shaft 502, a film tensioning roller 503, and a multipoint film feeding guide roller 504, through which the film passes in order;

The pressing roller in the pressing force adjusting device 501 is abutted against the film placing driving shaft 502 to press the film between the pressing roller and the film placing driving shaft 502;

The film releasing driving shaft 502 is driven to rotate by the speed reducing motor 505 to pull the film roll on the film rolling supporting mechanism 4 to rotate and release the film; the gear motor 505 may be provided as a micro gear motor 505;

Two ends of the film tensioning roller 503 are connected to the upright rods of the frame in a sliding manner through connectors 506, and the film which bypasses under the film tensioning roller is pressed down by self weight so as to tension the film;

The multi-drop guide roller 504 is used to constrain the planned film path.

The specific working procedure of the film releasing mechanism 5 is as follows:

The film is first pressed firmly against the film release drive shaft 502 by the press roller by the pressing force adjusting means 501 so that there is a sufficient friction force between the film and the film release drive shaft 502 to overcome the resistance. And then the film releasing driving shaft 502 is driven by the speed reducing motor 505 to pull the film roll on the film rolling supporting mechanism 4 to rotate and release the film. When the film is put, the film tensioning roller 503 moves downwards along the vertical rod under the action of gravity and continuously presses on the film, so that the film is always tensioned.

When the bag making mechanism 1 takes the film released by the film releasing mechanism 5, the film tensioning roller 503 moves upwards under the drive of the tensioned film; the multi-drop film guide roller 504 is used to constrain the film path and prevent the film from touching other equipment when entering the bag making mechanism 1.

Further, in order to accurately control the film releasing length of the film releasing mechanism, a film length sensor 507 for controlling the film releasing length is installed at the lower part of the film releasing mechanism 5, and when the film releasing mechanism works normally, the film releasing speed is equal to or higher than the film delivering speed, and the film releasing mechanism does not influence the action of the film delivering mechanism. However, when the film tension roller 503 moves downwards and is detected by the film length sensor 507, the film discharging mechanism 5 stops discharging the film, so that the phenomenon that the film is pulled to the ground due to excessive film discharging is avoided. The film release length can be adjusted by adjusting the mounting position of the film length sensor 507.

In the utility model, each part of a bag making mechanism 1, a bag pushing mechanism 2, a film rolling supporting mechanism 4 and a film releasing mechanism 5 is arranged on a corresponding frame.

Further, as shown in fig. 1, in order to further improve the integration level of the device, the vertical and oblique automatic bag-making and packaging apparatus further includes a material filling mechanism 6 disposed above the bag-making mechanism 1, where the material filling mechanism 6 is used to put a material 611 into the cavity of the bag-making mold core 3.

The material 611 is fed from the feed opening 602 of the storage chute 601, slides down the storage chute 601 under the force of gravity, and finally slides out of the discharge opening 603 into the cavity of the bag-forming mold core 3.

Further, the width and height of the cavity of the storage chute 601 gradually decrease from the feed inlet 602 to the discharge outlet 603, and the side wall at the feed inlet 602 is bent outwards to form a guide slope 604, so as to enlarge the width of the feed inlet.

The guide slope 604 plays a role in guiding the material 611 into the storage chute 601, and meanwhile, the wide feed inlet 602 is also convenient for the material 611 to enter the storage chute 601. The narrow outlet 603 can narrow the outflow position of the material 611, so as to facilitate filling and packaging.

Further, the width of the cavity should be limited to between 1-2 times the width of the material 611 to avoid side-by-side pinching of the material 611, preferably the width of the outlet 603 is slightly greater than the width of the material 611 and the width of the inlet 602 is between 1.5-1.8 times the width of the material 611.

Further, the bottom of the storage chute 601 is provided with a raised resistance-reducing wire 605 along the material flow direction, and the resistance-reducing wire 605 is made of a material with smooth surface, small friction coefficient and good wear resistance, such as a metal wire.

The drag reducing wire 605 attached to the bottom of the tank can reduce the contact area between the material 611 and the bottom of the tank, and reduce the friction resistance.

Further, the upper portion of the storage chute 601 is open, and a visual cover plate 606 is covered on the opening, so that the visual cover plate 606 can not only place foreign matters to mix into the storage chute 601, but also facilitate the observation of the state of the material 611.
