Background
In the production enterprises of diapers, sanitary napkins and the like, multiple layers of coiled materials are generally required to be laminated together, however, if the coiled materials of different layers are offset, the laminated and compounded products have serious quality problems, and therefore, the offset correction treatment is required to be performed on the offset coiled materials. At present, the traditional deviation rectifying methods generally have two types: 1) and each compound station is provided with a deviation rectifying device for positioning and rectifying deviation of one coiled material. However, the method cannot automatically position and correct the deviation of another type of coiled material according to the position of one type of coiled material, has extremely low deviation correction precision, and even if more advanced equipment can position and correct the deviation of another type of coiled material according to the position of one type of coiled material, the problem of low deviation correction precision is overcome, but the method cannot position and correct the deviation of two types of coiled materials simultaneously, has low deviation correction speed, and cannot meet the production requirements of high-quality and high-speed production lines. 2) Two deviation rectifying devices are arranged at each compound station to respectively carry out positioning deviation rectification on the two coiled materials. The method has the defects that the two deviation correction devices cannot be associated with each other, the mutual interference or resonance phenomenon cannot be effectively avoided, and the equipment cost is high.

At this moment, the driving part outputs power to the synchronous transmission mechanism, the synchronous transmission mechanism synchronously drives the left-handed screw component and the right-handed screw component to move to generate axial pushing or pulling force, and the rotation directions of the left-handed screw component and the right-handed screw component are different, so that the first amplitude deviation bracket drives the first deviation correction roller and the second amplitude deviation bracket drives the second deviation correction roller to deviate towards the opposite direction, that is, the first deviation correction roller deviates towards the left side, and the second deviation correction roller deviates towards the right side, at this moment, the first deviation correction roller which deviates towards the left side can push the upper layer to correct the material which deviates towards the right side to the left side, and meanwhile, the second deviation correction roller which deviates towards the right side synchronously pushes the lower layer to correct the material which deviates towards the left side to the right side, namely, the upper layer and lower layer materials synchronously complete positioning and deviation correction operation in.

As shown in fig. 1 to 3 and 5, a symmetrical deviation rectifying apparatus according to an embodiment of the present application includes: a main frame 100; the synchronous driving device 200 and the first deviation rectifying mechanism 300 and the second deviation rectifying mechanism 400 which are symmetrical in structure; the main frame 100 is used as a bearing member for installing and fixing the synchronous driving device 200, the first deviation correcting mechanism 300 and the second deviation correcting mechanism 400, the synchronous driving device 200 is used for outputting deviation correcting power and driving the first deviation correcting mechanism 300 and the second deviation correcting mechanism 400 to move synchronously, and the first deviation correcting mechanism 300 and the second deviation correcting mechanism 400 obtain the power and then synchronously and reversely deflect to position and correct the deviation of different layers of materials of the product which is deflected.
Specifically, the synchronous driving device 200 includes a driving element 210 disposed on the main frame 100, and a synchronous transmission mechanism 220 drivingly connected to the driving element 210; the first deviation correcting mechanism 300 includes a left-handed screw assembly 310 disposed on the main frame 100 and drivingly connected to the synchronous transmission mechanism 220, a first deviation bracket 320 disposed on a first side of the main frame 100 and drivingly connected to the left-handed screw assembly 310, and at least two first deviation correcting drums 330 disposed on the first deviation bracket 320 at intervals; the second deviation correcting mechanism 400 comprises a right-handed screw assembly 410 arranged on the main frame 100 and in driving connection with the synchronous transmission mechanism 220, a second deviation bracket 420 arranged on the second side of the main frame 100 and in driving connection with the right-handed screw assembly 410, and at least two second deviation correcting rollers 430 arranged on the second deviation bracket 420 at intervals; the distance between at least two first deviation rectification rollers 330 and the distance between at least two second deviation rectification rollers 430 jointly form a deviation rectification channel 500 for the product to pass through;
the power output by the driving member 210 synchronously drives the left-handed screw assembly 310 and the right-handed screw assembly 410 to move through the synchronous transmission mechanism 220, and the rotation directions of the left-handed screw assembly 310 and the right-handed screw assembly 410 are different, so that the first amplitude deviation bracket 320 drives the first deviation correction roller 330 and the second amplitude deviation bracket 420 drives the second deviation correction roller 430 to deviate towards opposite directions, thereby realizing positioning deviation correction of different layers of coiled materials of products which are already deviated in the deviation correction channel 500.
When the above-mentioned symmetrical deviation rectifying apparatus is used for positioning deviation rectifying work, different layers of materials of the product longitudinally pass through the deviation rectifying channel 500 formed by the space between the two first deviation rectifying rollers 330 and the space between the two second deviation rectifying rollers 430 in a longitudinal laminating manner. When the materials on different layers are relatively staggered and offset due to factors such as size errors and installation errors, the materials on the upper layer can be understood as materials on the upper layer and the lower layer, the materials on the upper layer are offset to the right by a distance, and the materials on the lower layer are offset to the left by a distance, so that potential quality hazards appear on the finished products after the materials are attached. At this time, the driving member 210 outputs power to the synchronous transmission mechanism 220, the synchronous transmission mechanism 220 synchronously drives the left-handed screw assembly 310 and the right-handed screw assembly to move to generate axial pushing or pulling force, since the rotation directions of the left-handed screw assembly 310 and the right-handed screw assembly are different, the first amplitude-deviation bracket 320 drives the first deviation-correcting roller 330 and the second amplitude-deviation bracket 420 drives the second deviation-correcting roller 430 to deviate in opposite directions, it can be understood that the first deviation correcting roller 330 is deviated to the left side and the second deviation correcting roller 430 is deviated to the right side, and at this time, the first deviation rectifying roller 330 that is deviated to the left side pushes the material deviated to the right side of the upper layer to be rectified to the left side, meanwhile, the second deviation rectifying roller 430 which is deviated to the right side synchronously pushes the material of the lower layer which is deviated to the left side to be rectified to the right side, that is, the upper and lower layers of material synchronously complete the positioning deviation rectifying operation in the same time. Compared with the traditional deviation rectifying equipment, the deviation rectifying equipment can realize high-speed positioning and rectifying of the coiled materials of different layers, meets the requirements of high-quality and high-speed production, and can eliminate the resonance interference phenomenon and reduce the cost expenditure because only one driving part 210 is adopted to output power.
Referring to the figure, the two first deviation rectification rollers 330 and the two second deviation rectification rollers 430 are arranged in a rectangular shape, and according to the preset product conveying direction, the materials in different layers pass through the space formed by the two first deviation rectification rollers 330 and the two second deviation rectification rollers 430 at intervals in the longitudinal direction, that is, the deviation rectification channel 500. When the equipment of this application carries out the work of rectifying, can understand that four cylinders of rectifying are changed into rhombus arrangement structure by rectangle arrangement structure gradually, and two relative limits that the interval takes place to reduce or grow promptly are through the material edge butt with different layers, exert thrust and rectify material spatial position or transmission path and accomplish the location and rectify.
The first deviation-correcting roller 330 and the second deviation-correcting roller 430 are combined, that is, they are mounted on the corresponding deviation bracket through a rotating shaft, and the rotating shaft is sleeved with a fixed roller to ensure good rotation, so as to form good guidance for the product. The end part of the rotating shaft far away from the partial amplitude support is provided with a shaft end positioning sleeve, so that the roller is prevented from slipping, and dust, water and the like are prevented from entering the roller to cause damage.
The driving member 210 may be a motor, such as a stepping motor, a servo motor, etc., but in other embodiments, a person skilled in the art may also use other existing products or devices as long as the driving member can output power to synchronously drive the left-handed and right-handed screw assemblies.
With reference to fig. 1, in order to improve the assembly compactness and the motion performance of each component of the lifting apparatus, on the basis of the above embodiment, the first side and the second side of the main frame 100 are respectively provided with an installation groove 110, the left-handed screw assembly 310 and the right-handed screw assembly 410 are respectively embedded and fixed in the two installation grooves 110, the left-handed screw assembly 310 and the right-handed screw assembly 410 respectively include a screw 411, a screw nut 412 screwed on the screw 411, and a pushing block 413 sleeved and fixed on the screw nut 412, the pushing block 413 is provided with a pushing arm 414 extending out of the installation groove 110, and the pushing arm 414 is connected with the first amplitude-biasing bracket 320 and the second amplitude-biasing bracket 420. Namely, the mounting holes are formed in the two side groove walls of the mounting groove 110 in the length direction, so that the two end parts of the screw rod 411 can be stably embedded in the mounting holes, the mounting is firm, the occupied space can be reduced, and the whole structure of the equipment is more compact; in addition, the screw rod nut 412 is provided with the pushing device, and the extending pushing arm 414 is connected with the first amplitude deviation bracket 320 and the second amplitude deviation bracket 420, so that the axial thrust of the spiral playground can be applied to the two amplitude deviation brackets more optimally, and the problem that the clamping is caused due to the overlarge stress on one side and the driving effectiveness is influenced is avoided.
It should be noted that, the driving member 210 is preferably a motor, and two sets of lead screw assemblies with different rotation directions are characterized in that: when the power motor drives clockwise, the two groups of screw rod assemblies rotate clockwise synchronously; and when the power motor drives anticlockwise, the two groups of screw rod assemblies rotate anticlockwise synchronously. That is, when the lead screw 411 of the left-handed lead screw assembly 310 rotates clockwise, the lead screw nut 412 thereon will generate a left-handed axial thrust; otherwise, right-side axial tension is generated. When the lead screw 411 of the right-handed lead screw assembly 410 rotates clockwise, the lead screw nut 412 on the right-handed lead screw assembly generates right-handed axial tension; otherwise, left axial thrust is generated. Thus, when the power motor is driven clockwise, the first amplitude-shifting bracket 320 connected to the left-handed screw assembly 310 will generate a left-sided amplitude-shifting, while the second amplitude-shifting bracket 420 connected to the right-handed screw assembly 410 will generate a right-sided amplitude-shifting; when the power motor is driven counterclockwise, the first amplitude-shifting bracket 320 connected to the left-handed screw assembly 310 will generate a right-handed amplitude, and the second amplitude-shifting bracket 420 connected to the right-handed screw assembly 410 will generate a left-handed amplitude.
Further, the left-handed screw assembly 310 and the right-handed screw assembly 410 each further include an angular contact bearing 415, a mounting hole is formed in a groove wall of the mounting groove 110, and the screw rod 411 is rotatably disposed in the mounting hole through the angular contact bearing 415. By installing the angular contact bearing 415, the lead screw 411 rotates more smoothly and stably, and meanwhile, the friction and the abrasion generated by direct rotational contact with the groove wall of the mounting groove 110 can be reduced, thereby being beneficial to prolonging the service life of equipment. Of course, in other embodiments, other structures or components may be adopted to realize the stable installation of the left and right screw assemblies 410, which may be selected according to actual needs and will not be described herein again.
In order to control the deviation rectification of the equipment within a certain range to adapt to most products with different sizes, the screw rod 411 is provided with a first limiting clamping protrusion 411a close to the first end and a second limiting clamping protrusion 411b close to the second end, and when the first deviation rectification roller 330 deviates to a first limit position, the screw rod nut 412 is abutted to the first limiting clamping protrusion 411 a; when the second deviation rectifying roller 430 deviates to a second limit position, the lead screw nut 412 abuts against the second limit clamping protrusion 411 b. Therefore, the lead screw nut 412 is abutted against the first limiting clamping protrusion 411a or the second limiting clamping protrusion 411b, so that the first deviation rectifying roller 330 and the second deviation rectifying roller 430 can be stopped at two positions of the first limit and the second limit, and more accurate positioning can be realized.
With continued reference to fig. 4, in addition, in order to ensure that the output power of the motor can be synchronously and accurately transmitted to the left-handed screw assembly 310 and the right-handed screw assembly by the same amount to achieve the synchronous motion of the first deviation-correcting roller 330 and the second deviation-correcting roller 430, in an alternative embodiment, the synchronous transmission mechanism 220 includes a driving gear 221 connected to the power shaft of the driving member 210, a first driven gear 222 connected to the left-handed screw assembly 310, and a second driven gear 223 connected to the right-handed screw assembly 410, wherein the driving gear 221 includes a first annular tooth portion and a second annular tooth portion which are coaxially arranged in the longitudinal direction; the synchronous transmission mechanism 220 further includes a first toothed synchronous belt 224 and a second toothed synchronous belt 225, the first toothed synchronous belt 224 is engaged and sleeved on the first annular tooth portion and the first driven gear 222, and the second toothed synchronous belt 225 is engaged and sleeved on the second annular tooth portion and the second driven gear 223. By adopting the transmission structure of the gear and the toothed synchronous belt, the stable transmission of power can be ensured, the slipping caused by overlarge load or assembly error can be prevented, and the reliability of the synchronous motion realization of the first deviation rectifying roller 330 and the second deviation rectifying roller 430 can be ensured.
It should be noted that the transmission structure of the gear and the tooth-shaped synchronous belt may be replaced by a sprocket, a chain, a worm gear, and the like, as long as synchronous transmission of power can be achieved, and those skilled in the art can flexibly select and implement the transmission structure by using the prior art.
On the basis of any of the above embodiments, the symmetrical deviation rectifying apparatus further includes a wear reduction assembly 600, the first deviation bracket 320 and the second deviation bracket 420 both include a deviation plate 321 and a deviation seat 322 for mounting the first deviation roller 330 and the second deviation roller 430, the deviation plate 321 is provided with a limiting groove opposite to the mounting groove 110, the wear reduction assembly 600 includes a radial bearing 610 rotatably embedded in the limiting groove and a pressing plate 620 pressed on the deviation plate 321 for preventing the radial bearing 610 from loosening, and the pushing arm 414 passes through the pressing plate 620 and is connected with the radial bearing 610. Therefore, the deflection bracket (i.e. the first deflection bracket 320 and the second deflection bracket 420) can be more smoothly and reliably connected with the pushing arm 414 of the pushing block 413 in a rotating and driving manner, and can be supported and positioned at the same time, so that the rotating friction and wear are reduced.
Further, the offset plate 321 is clearance-fitted to the main frame 100. Therefore, the relative motion resistance generated when the amplitude-offset bracket rotates due to the direct contact of the amplitude-offset plate 321 and the side wall of the main frame 100 can be avoided, so that the normal deflection of the amplitude-offset bracket is influenced, and meanwhile, the friction and the abrasion are generated, and the service life of the equipment is influenced.
With reference to fig. 1 and fig. 3, on the basis of any of the above embodiments, the symmetrical deviation rectifying apparatus further includes a first positioning guide mechanism 700 and a second positioning guide mechanism 800, which are symmetrically arranged, the first positioning guide mechanism 700 is used for guiding and positioning the first deviation frame 320, and the second positioning guide mechanism 800 is used for guiding and positioning the second deviation frame 420; the first positioning guide mechanism 700 and the second positioning guide mechanism 800 each include a slide rail 810 disposed on the main frame 100, and a slider 820 slidably fitted on the slide rail 810, the slider 820 is provided with a connecting arm 821, and the connecting arm 821 is respectively connected to the first amplitude-shifting bracket and the second amplitude-shifting bracket; the slide rail 810 and the lead screw 411 form an included angle, so that the first deviation rectifying roller 330 and the second deviation rectifying roller 430 realize arc overturning and swinging under the combined motion of the slide rail 810 and the lead screw 411. Therefore, the sliding block 820 is connected with the two amplitude deflection plates 321 through the connecting arm 821 to provide oblique partial motion of the amplitude deflection bracket, the pushing block 413 is connected with the amplitude deflection plates 321 through the pushing arm 414 to provide longitudinal partial motion of the amplitude deflection bracket, the amplitude deflection bracket forms arc line overturning swing in a plane through the combination of the oblique partial motion and the longitudinal partial motion, the motion stroke is small, the space position requirement of positioning and deviation rectifying work can be greatly reduced, meanwhile, the sliding fit between the sliding block 820 and the sliding rail 810 can also form a guiding effect on the amplitude deflection bracket, and the reliable swing of the amplitude deflection bracket on a preset path is guaranteed.
In particular, since the slider 820 is connected to the amplitude-deflecting plate 321 through the connecting arm 821, the amplitude-deflecting plate 321 is also in a rotation fit relationship with the connecting arm 821 during the deviation correction process, and in order to reduce the influence of rotation friction and improve the smoothness of rotation, the connecting arm 821 can also be connected to the amplitude-deflecting plate 321 through the radial bearing 610, so as to eliminate the above adverse effect.
Further, the first side and the second side of the main frame 100 are both provided with a damping slot 120, and the sliding block 820 can slidably abut against the slot wall of the damping slot 120 to eliminate the vibration of the first deviation rectifying roller 330 and the second deviation rectifying roller 430 in the direction perpendicular to the moving direction of the sliding block 820. The extending direction of the groove wall of the vibration damping groove 120 is perpendicular to the deflection direction of the two deviation rectifying rollers, that is, in the moving process of the slider 820, the slider 820 can be limited by the interference with the groove wall of the vibration damping groove 120, so that the first deviation rectifying roller 330 and the second deviation rectifying roller are limited to vibrate in the direction perpendicular to the moving direction, and the stability of deflection is improved.
