Description

Technical Field

[0001] The present invention relates to the technical field of thin film processing, and particularly to a device for processing an easy-to-tear line of an easy-to-tear packaging composite film. Background Art

[0002] As a common plate, acrylic plates are widely used in many fields such as construction, advertising, medicine, and transportation. During its packaging process, in order to protect the surface of the plate from scratches, contamination and other damages, a film laminating treatment is usually carried out. Film lamination can not only protect the plate, but also maintain its smoothness and beauty during transportation and storage.

[0003] The design of the easy-to-tear line is mainly to facilitate users to easily and accurately tear the packaging film without using scissors or other tools. During the film lamination production process, one or more intermittent lines are pre-cut on the film lamination through a die or a cutter. After the film lamination is attached to the plate, these lines form the easy-to-tear line. This design can improve the user experience and reduce packaging damage and product loss caused by improper tearing.

[0004] After searching the prior art for "a device for facilitating the processing of easy-to-tear lines", the publication number is "CN216635618U". This device drives the pressure plate to rotate synchronously through the friction of the bag body, thereby driving the cutting tool disc to rotate synchronously, realizing the continuous operation of the cutting edges arranged at intervals, and processing the easy-to-tear line on the film. Due to the cooperation between the cutting edges of the cutting tool disc and the annular groove of the conveying roller, it is ensured that the cutting edges can penetrate the film, thus ensuring the forming quality of the easy-to-tear line. However, during the conveying process of the film, due to its own certain ductility, the film is prone to shift during the stretching conveying process, resulting in the inclination of the easy-to-tear line processing and affecting the forming of the easy-to-tear line. Summary of the Invention

[0005] Based on this, it is necessary to provide a device for processing an easy-to-tear line of an easy-to-tear packaging composite film for the problem that the film is prone to shift during the stretching conveying process, resulting in the inclination of the easy-to-tear line processing and affecting the forming of the easy-to-tear line.

[0006] An easy-to-tear packaging composite film easy-to-tear line processing device includes: a processing frame, two conveying rollers are rotatably connected to the inner side of the processing frame, and a composite packaging film is arranged on the surface of the conveying rollers; a processing mechanism, the processing mechanism is arranged inside the processing frame, and the upper end of the processing mechanism penetrates above the composite packaging film; wherein, the processing mechanism includes a film positioning component arranged between the two conveying rollers, the film positioning component is fixedly connected to the inner wall of the processing frame, the upper end of the film positioning component penetrates above the composite packaging film, a cutting position component is arranged below the film positioning component, an adjusting component is arranged inside the cutting position component, and a servo motor is installed on one side of the film positioning component.

[0007] In one embodiment, the film positioning assembly includes a processing guide frame fixedly connected to the inner wall of the processing frame. The inner bottom wall of the processing guide frame is in contact with the surface of the composite packaging film. A plurality of ventilation holes are formed in the inner bottom wall of the processing guide frame, and the plurality of ventilation holes are distributed in an array. Two smoothing cross shafts are rotatably connected to the inner wall of the processing guide frame, and the ends of the smoothing cross shafts penetrate to the outside of the processing guide frame. One end of one of the smoothing cross shafts is fixedly connected to the output shaft of the servo motor. Two soft rubber spiral rolls are fixedly connected to the surface of the smoothing cross shaft. When the composite packaging film passes through the two conveying rollers, the movement range of the composite packaging film is maintained under the action of the processing guide frame, and the situation of the composite packaging film shifting during movement is reduced. Moreover, during the rotation of the two soft rubber spiral rolls, due to the setting of the soft rubber spiral rolls, the upper surface of the composite packaging film is smoothed. At the same time, a rectangular groove is formed in the inner bottom wall of the processing guide frame below the soft rubber spiral roll, so that the contact position is allowed to sink into the rectangular groove during the smoothing process of the soft rubber spiral roll, improving the smoothing effect of the soft rubber spiral roll. And by providing the ventilation holes, the situation of the composite packaging film adhering to and adsorbing to the inner bottom wall of the processing guide frame during movement is reduced, maintaining the smooth movement effect of the composite packaging film and improving the stability of the easy tear line processing.

[0008] In one embodiment, the cutting position assembly includes a bottom rotating shaft rotatably connected to the lower end of the processing guide frame. An inner rotating shaft is rotatably connected to the inner side of the processing guide frame. Gears are fixedly connected to the ends of the inner rotating shaft and the bottom rotating shaft, and the two gears are meshed. A tubular sleeve is sleeved on the surface of the bottom rotating shaft, an inner clamping groove is formed in the inner wall of the tubular sleeve, and a cutting seat is fixedly connected to the surface of the tubular sleeve. By setting the bottom rotating shaft and the inner rotating shaft, the tubular sleeve can rotate synchronously with the surface of the bottom rotating shaft at the clamping position and drive the cutting seat to rotate synchronously. The widest diameter of the bottom rotating shaft is the same as the diameter of the inner rotating shaft. At the same time, under the action of the two meshed gears, the stable rotation speeds of the inner rotating shaft and the bottom rotating shaft are the same and the rotation directions are opposite.

[0009] In one embodiment, the adjustment component includes a positioning and mounting frame fixedly connected to the lower end of the processing guide frame. The positioning and mounting frame is sleeved outside the cutting seat. A sliding horizontal groove is formed on one side of the positioning and mounting frame close to the servo motor. Two positioning sliding frames are slidably connected to the inner wall of the sliding horizontal groove. The surface of the positioning and mounting frame away from the inner wall of the sliding horizontal groove contacts the surface of the cutting seat. The end of the positioning sliding frame away from the sliding horizontal groove is fixedly connected with a positioning collar. The inner wall of the positioning collar is rotatably connected to the surface of the bottom rotating shaft. By sliding the two positioning sliding frames on the inner wall of the sliding horizontal groove, the positioning collar can form a positioning effect on both ends of the tubular sleeve shaft, reducing the deviation during the processing of the tear line. Moreover, two counterbores are formed on the surface of the tubular sleeve shaft, and a positioning hexagon socket head bolt is arranged inside. The bolt penetrates into the bottom rotating shaft and is threadedly connected thereto for positioning purposes.

[0010] In one embodiment, two first belt pulleys are arranged on one side of the processing guide frame away from the servo motor. The first belt pulleys are fixedly connected to the surface of the adjacent smoothing horizontal shaft. A transmission belt is sleeved on the surfaces of the two first belt pulleys. Two second belt pulleys are arranged between the two first belt pulleys. The second belt pulleys are fixedly connected to the surface of the cutting position component. The second belt pulleys are in contact with the surface of the adjacent transmission belt. The surface of the transmission belt is in an S shape along the inner sides of the two second belt pulleys, so that the two second belt pulleys rotate in opposite directions. By driving the servo motor to drive one of the smoothing horizontal shafts to rotate, at this time, due to the cooperation of the transmission belt and the first belt pulley, the two smoothing horizontal shafts rotate in the same direction and at the same speed. At the same time, the two second belt pulleys drive the inner rotating shaft and the bottom rotating shaft to rotate at the same speed respectively.

[0011] In one embodiment, a hinge frame is hinged to the inner wall of the cutting seat. One side of the hinge frame is fixedly connected with an elastic sheet. The elastic sheet is fixedly connected to the inner wall of the cutting seat. The side of the hinge frame away from the elastic sheet is fixedly connected with a cutting head. The surface of the cutting seat contacts the surface of the positioning and mounting frame away from the inner wall of the sliding horizontal groove. When the bottom rotating shaft drives the cutting seat to rotate through the tubular sleeve shaft, the cutting head contacts the inner wall away from the sliding horizontal groove and remains in the cutting seat. When the cutting end of the cutting head moves to no longer contact the inner wall of the positioning and mounting frame, it passes through the adjacent ventilation hole and cuts the composite packaging film to form a tear line. An inclined angle is arranged on the inner wall of the cutting seat close to the arc surface of the cutting seat. When the cutting head flips, the hinge frame will abut against the inclined angle to control the flipping angle of the cutting head and maintain good cutting stability.

[0012] In one embodiment, the soft rubber spiral coils are spirally distributed along the surface of the flattening horizontal axis. The spiral directions of the two soft rubber spiral coils are opposite. A plurality of soft rubber sheets are fixedly connected to the outer edge of the soft rubber spiral coils. The surface of the soft rubber sheets away from the soft rubber spiral coils is in contact with the surface of the composite packaging film. The end of the soft rubber spiral coil near the flattening horizontal axis forms a funnel-like shape, and the plurality of soft rubber sheets are evenly distributed in a ring shape. When the composite packaging film moves from the flattening horizontal axis far from the servo motor towards the flattening horizontal axis close to the servo motor, the spiral arrangement of the soft rubber spiral coils at this time forms a flattening effect on the surface of the composite packaging film. Moreover, the end of the soft rubber spiral coil near the flattening horizontal axis is arranged in a funnel-like shape. When the soft rubber sheets contact the composite packaging film, the soft rubber sheets bend towards the surface of the flattening horizontal axis, forming a thrust force on the surface of the composite packaging film towards the inner wall of the adjacent processing guide frame. When wrinkles are generated due to the offset of the surface of the composite packaging film, the side where the wrinkles accumulate will not be in sufficient contact with the soft rubber spiral coils and the soft rubber sheets, while the side without accumulated wrinkles is in full contact with the soft rubber spiral coils and the soft rubber sheets. At this time, the offset composite packaging film will be automatically adjusted towards the center line of the processing guide frame, maintaining the stable movement effect of the composite packaging film and improving the stability of the easy tear line processing.

[0013] In one embodiment, the adjustment component further includes an embedded welding strip fixedly connected to the surface of the bottom rotating shaft. The embedded welding strip is clamped with the inner wall of the inner card slot. A positioning notch is formed on the surface of the embedded welding strip, and the inner wall of the positioning collar is in contact with the inner wall of the positioning notch. When the bottom rotating shaft rotates, the tubular sleeve shaft is driven to rotate synchronously through the cooperation of the embedded welding strip and the inner card slot. The setting of the positioning notch enables the positioning collar to achieve the positioning effect on the tubular sleeve shaft when the bottom rotating shaft rotates.

[0014] In one embodiment, a support frame is arranged below the processing frame. A cleaning component for cleaning the cutting head that rotates to the lower side position of the positioning mounting frame and pops out is connected to the support frame through a control component. When the cutting head rotates to the lower side position of the positioning mounting frame and cuts the composite packaging film to form an easy tear line, the cutting head rotates out of the positioning mounting frame. At this time, the cutting head is cleaned by the cleaning component, reducing the possibility that the dirt and debris adhered to the cutting head affect the next cutting. After the cleaning is completed, the control component controls the cleaning component to reverse, so as to clean the dirt adhered to the cleaning component and facilitate the next use.

[0015] In one embodiment, the cleaning component includes a long shaft, on which two oppositely arranged connecting rings with a three-quarter annular cross-section and rotatably connected to the long shaft are nested. One end of each connecting ring extends upward and bends, and a connecting plate is fixed to the upwardly bent part of the connecting ring. A cleaning plate for wiping and cleaning the cutting head is fixed to the end of the connecting plate. The two cleaning plates are arranged oppositely, and a cleaning cotton cloth adapted to the cleaning plate is nested on the cleaning plate.

[0016] In the above-mentioned easy-tear packaging composite film easy-tear line processing device, the film positioning component is provided to smooth the composite packaging film, reducing the occurrence of wrinkles in the process of moving the composite packaging film. And in the case of the composite packaging film being offset, it can also assist the composite packaging film to reset to the middle line of the processing guide frame, maintaining a more stable processing state of the composite packaging film during processing, reducing the occurrence of offset wrinkles of the composite packaging film, and ensuring the processing effect of the formation of the easy-tear line.

[0017] During the processing of the easy-tear line, when the cutting end of the cutting head pierces the composite packaging film, the device can be positioned through the sponge extrusion bladder, avoiding the offset of the composite packaging film in the surrounding area during the cutting process and forming a relatively firm positioning effect on the cutting head. When the cutting end of the cutting head processes the composite packaging film, it will pass through the composite packaging film and enter the notch of the extrusion bladder, forming a stable processing effect on the composite packaging film.

[0018] Among them, the adjustment component can assist in playing a relatively firm auxiliary positioning role for the cutting head when the cutting position component works, ensuring the processing effect of the cutting position component on the formation of the easy-tear line, and can also cooperate with the tubular sleeve shaft to adjust the processing position of the easy-tear line, meeting the processing requirements for easy-tear lines at different positions.

The term "and / or" used in the description of the present invention includes any and all combinations of one or more of the related listed items.

[0041] The following will be combined with Figures 1 - 14 Describe the processing device for the easy-tear line of the easy-tear packaging composite film of the present invention, including: a processing frame 100, two conveying rollers 110 are rotatably connected to the inner side of the processing frame 100, and a composite packaging film 200 is arranged on the surface of the conveying rollers 110; a processing mechanism 300, the processing mechanism 300 is arranged inside the processing frame 100, and the upper end of the processing mechanism 300 penetrates above the composite packaging film 200; wherein, the processing mechanism 300 includes a film positioning component 310 arranged between the two conveying rollers 110, the film positioning component 310 is fixedly connected to the inner wall of the processing frame 100, the upper end of the film positioning component 310 penetrates above the composite packaging film 200, a cutting position component 320 is arranged below the film positioning component 310, an adjusting component 330 is arranged inside the cutting position component 320, and a servo motor 340 is installed on one side of the film positioning component 310;

[0042] As Figures 1 - 14As shown in the figure, the film positioning assembly 310 includes a processing guide frame 311 fixedly connected to the inner wall of the processing frame 100. The inner bottom wall of the processing guide frame 311 contacts the surface of the composite packaging film 200. A plurality of ventilation holes 312 are formed in the inner bottom wall of the processing guide frame 311, and the plurality of ventilation holes 312 are arranged in an array. Two smoothing cross shafts 313 are rotatably connected to the inner wall of the processing guide frame 311, and the ends of the smoothing cross shafts 313 penetrate to the outside of the processing guide frame 311. One end of one of the smoothing cross shafts 313 is fixedly connected to the output shaft of the servo motor 340. Two soft rubber spiral rolls 314 are fixedly connected to the surface of the smoothing cross shaft 313. Two first belt pulleys 316 are arranged on the side of the processing guide frame 311 away from the servo motor 340. The first belt pulleys 316 are fixedly connected to the surface of the adjacent smoothing cross shaft 313. A transmission belt 317 is sleeved on the surface of the two first belt pulleys 316. Two second belt pulleys 318 are arranged between the two first belt pulleys 316. The second belt pulleys 318 are fixedly connected to the surface of the cutting position assembly 320. The second belt pulleys 318 are in contact with the surface of the adjacent transmission belt 317. The soft rubber spiral rolls 314 are spirally distributed along the surface of the smoothing cross shaft 313. The spiral directions of the two soft rubber spiral rolls 314 are opposite. A plurality of soft rubber sheets 315 are fixedly connected to the outer edge of the soft rubber spiral rolls 314. The surface of the soft rubber sheet 315 away from the soft rubber spiral roll 314 contacts the surface of the composite packaging film 200;

[0043] When the composite packaging film 200 passes through the two conveyor rollers 110, the processing guide frame 311 keeps the moving range of the composite packaging film 200, reduces the occurrence of the situation that the composite packaging film 200 deviates during the moving process. And during the rotation of the two soft rubber spiral rolls 314, through the setting of the soft rubber spiral rolls 314, the upper surface of the composite packaging film 200 is smoothed. At the same time, a rectangular groove is formed in the inner bottom wall of the processing guide frame 311 below the soft rubber spiral rolls 314, so that when the soft rubber spiral rolls 314 smooth the composite packaging film 200, the contact position is allowed to sink into the rectangular groove, improving the smoothing effect of the soft rubber spiral rolls 314. And by arranging the ventilation holes 312, the situation that the composite packaging film 200 adheres and adsorbs to the inner bottom wall of the processing guide frame 311 during the moving process is reduced, maintaining the smooth moving effect of the composite packaging film 200 and improving the stability of the easy tear line processing. The surface of the transmission belt 317 is in an S shape along the inner sides of the two second belt pulleys 318, so that the rotation directions of the two second belt pulleys 318 are opposite. By driving the servo motor 340 to drive one of the smoothing cross shafts 313 to rotate, at this time, due to the cooperation of the transmission belt 317 and the first belt pulley 316, the two smoothing cross shafts 313 rotate in the same direction and at the same speed. At the same time, the two second belt pulleys 318 drive the inner shaft 329 and the bottom shaft 321 inside to rotate at the same speed respectively;

[0044] The soft rubber spiral roll 314 forms a funnel-like shape near the end of the flattening horizontal shaft 313, and multiple soft rubber sheets 315 are evenly distributed in a ring. When the composite packaging film 200 moves from the flattening horizontal shaft 313 in the direction away from the servo motor 340 towards the flattening horizontal shaft 313 in the direction close to the servo motor 340, at this time, the soft rubber spiral roll 314 is spirally arranged to form a flattening effect on the surface of the composite packaging film 200. And the soft rubber spiral roll 314 is arranged in a funnel-like shape near the end of the flattening horizontal shaft 313. When the soft rubber sheet 315 contacts the composite packaging film 200, the soft rubber sheet 315 bends towards the surface of the flattening horizontal shaft 313, forming a thrust on the surface of the composite packaging film 200 towards the inner wall of the adjacent processing guide frame 311. Among them, when the surface of the composite packaging film 200 is offset to generate wrinkles, the side where the wrinkles accumulate will not be in sufficient contact with the soft rubber spiral roll 314 and the soft rubber sheet 315, while the side without accumulated wrinkles is in full contact with the soft rubber spiral roll 314 and the soft rubber sheet 315. At this time, the offset composite packaging film 200 will be automatically adjusted towards the center line of the processing guide frame 311, maintaining the stable movement effect of the composite packaging film 200 and improving the stability of the easy-tear line processing;

[0045] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11As shown in the figure, the cutting position component 320 includes a bottom rotating shaft 321 rotatably connected to the lower end of the processing guide frame 311. An internal rotating shaft 329 is rotatably connected to the inner side of the processing guide frame 311. Gears 328 are fixedly connected to the ends of both the internal rotating shaft 329 and the bottom rotating shaft 321. The two gears 328 are meshed and connected. A tubular sleeve shaft 322 is sleeved on the surface of the bottom rotating shaft 321. An inner card slot 327 is provided on the inner wall of the tubular sleeve shaft 322. A cutting seat 323 is fixedly connected to the surface of the tubular sleeve shaft 322. A hinge frame 325 is hinged to the inner wall of the cutting seat 323. A spring piece 324 is fixedly connected to one side of the hinge frame 325. The spring piece 324 is fixedly connected to the inner wall of the cutting seat 323. A cutting head 326 is fixedly connected to the side of the hinge frame 325 away from the spring piece 324. A sponge extrusion bladder 3210 is fixedly connected to the surface of the internal rotating shaft 329. The sponge extrusion bladder 3210 is in contact with the surface of the composite packaging film 200. An extrusion bladder notch 3211 is provided on the surface of the sponge extrusion bladder 3210. Among them, by setting the bottom rotating shaft 321 and the internal rotating shaft 329, it can be formed that the tubular sleeve shaft 322 can rotate synchronously with the surface of the bottom rotating shaft 321 at the clamping position and drive the cutting seat 323 to rotate synchronously. The widest diameter of the bottom rotating shaft 321 is the same as the diameter of the internal rotating shaft 329. At the same time, under the action of the two meshed gears 328, the internal rotating shaft 329 and the bottom rotating shaft 321 are kept rotating stably at the same speed and in opposite directions;

[0046] The surface of the cutting seat 323 is in contact with the inner wall of the positioning and mounting frame 331 away from the sliding transverse groove 332. When the bottom rotating shaft 321 drives the cutting seat 323 to rotate through the tubular sleeve shaft 322, the cutting head 326 is in contact with the inner wall away from the sliding transverse groove 332 and remains inside the cutting seat 323. When the cutting end of the cutting head 326 moves to no longer contact the inner wall of the positioning and mounting frame 331, it passes through the adjacent ventilation holes 312 and cuts the composite packaging film 200 to form a tear line. An inclined angle is provided on the inner wall of the cutting seat 323 near the arc surface of the cutting seat 323. When the cutting head 326 flips, the hinge frame 325 will abut against the inclined angle to control the flipping angle of the cutting head 326 and maintain good cutting stability. The diameter of the cutting seat 323 is the same as the diameter of the sponge extrusion bladder 3210. And because the cutting seat 323 and the sponge extrusion bladder 3210 rotate in opposite directions and at the same speed, when the cutting head 326 cuts the composite packaging film 200, the cutting end of the cutting head 326 passes through the composite packaging film 200 and enters the inside of the extrusion bladder notch 3211. The sponge extrusion bladder 3210 forms a positioning effect around the tear line of the composite packaging film 200 to maintain the processing effect of the tear line of the composite packaging film 200;

[0047] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 9 、Figure 12 As shown, the adjustment component 330 includes a positioning and mounting frame 331 fixedly connected to the lower end of the processing guide frame 311. The positioning and mounting frame 331 is sleeved outside the cutting seat 323. A sliding transverse groove 332 is formed on one side of the positioning and mounting frame 331 close to the servo motor 340. Two positioning sliding frames 333 are slidably connected to the inner wall of the sliding transverse groove 332. The surface of the positioning and mounting frame 331 away from the inner wall of the sliding transverse groove 332 contacts the surface of the cutting seat 323. A positioning collar 334 is fixedly connected to the end of the positioning sliding frame 333 away from the sliding transverse groove 332. The inner wall of the positioning collar 334 is rotatably connected to the surface of the bottom rotating shaft 321. The adjustment component 330 further includes an embedded welding strip 335 fixedly connected to the surface of the bottom rotating shaft 321. The embedded welding strip 335 is clamped with the inner wall of the inner card slot 327. A positioning notch 338 is formed on the surface of the embedded welding strip 335. The inner wall of the positioning collar 334 contacts the inner wall of the positioning notch 338. A threaded hole 336 is formed on one side of the positioning and mounting frame 331 close to the sliding transverse groove 332. A positioning bolt 337 is arranged on the inner wall of the threaded hole 336;

[0048] By sliding the two positioning sliding frames 333 on the inner wall of the sliding transverse groove 332, the positioning collar 334 can form a positioning effect on both ends of the tubular sleeve shaft 322, reducing the occurrence of deviation during the processing of the tear line. Two counterbores are formed on the surface of the tubular sleeve shaft 322, and a positioning hexagon socket head bolt is arranged inside. The bolt penetrates into the bottom rotating shaft 321 and is threadedly connected thereto for positioning purposes. When the bottom rotating shaft 321 rotates, the tubular sleeve shaft 322 is driven to rotate synchronously through the cooperation of the embedded welding strip 335 and the inner card slot 327. The setting of the positioning notch 338 enables the positioning collar 334 to satisfy the positioning effect of the elastic piece 324 on the tubular sleeve shaft 322 when the bottom rotating shaft 321 rotates. The positioning sliding frame 333 achieves the positioning effect through the positioning bolt 337 arranged to pass through the threaded hole 336 formed on the surface of the positioning and mounting frame 331.

[0049] As Figure 13 and Figure 14 shown in, a support frame 400 is arranged below the processing frame 100. A cleaning component 500 for cleaning the cutting head 326 that rotates to the lower side position of the positioning and mounting frame 331 and pops out is connected to the support frame 400 through a control component 600. When the cutting head 326 rotates to the lower side position of the positioning and mounting frame 331, after the cutting head 326 forms a tear line by cutting the composite packaging film 200, the cutting head 326 spins out of the positioning and mounting frame 331. At this time, the cutting head 326 is cleaned by the cleaning component 500, reducing the possibility that the dirt and debris adhered to the cutting head 326 affect the next cutting. After the cleaning is completed, the cleaning component 500 is controlled by the control component 600 to reverse, so as to clean the dirt adhered to the cleaning component 500 and facilitate the next use.

[0050] As Figure 13 and Figure 14 shown, the cleaning component 500 includes a long shaft 510, on which two oppositely arranged connecting rings 511 with a three-quarter annular cross-section are nested and rotatably connected to the long shaft 510. One end of each connecting ring 511 extends upward and bends. A connecting plate 512 is fixed to the upwardly bent portion of the connecting ring 511. A cleaning plate 513 for wiping and cleaning the cutting head 326 is fixed to the end of the connecting plate 512. The two oppositely arranged connecting rings 511 are supported by the long shaft 510. Each connecting ring 511, the adjacent connecting plate 512 and the cleaning plate 513 are of an integrated structure. A cleaning cotton cloth adapted to the cleaning plate 513 is nested on the cleaning plate 513.

[0051] As Figure 13 and Figure 14 shown, the control component 600 includes a support 610 arranged below the processing frame 100. A slideway 611 is integrated on the support 610. A slider 612 is slidably connected to the slideway 611. One end of the slider 612 extends out of the slideway 611. A connecting rod 613 is hingedly connected to the end of the slider 612 extending out of the slideway 611. A swing rod 614 with a V-shaped cross-section is hingedly connected to the end of the connecting rod 613 away from the slider 612. The end of the swing rod 614 away from the connecting rod 613 is fixed to the long shaft 510. A cylinder 615 for driving the slider 612 to slide in the slideway 611 is fixed on the support 610.

[0052] As Figure 13 and Figure 14 shown, two first ear seats are further arranged below the processing frame 100 beside the support 610. A first driven shaft 700 rotatably connected to the first ear seats penetrates between the two first ear seats. The swing rod 614 is nested outside the first driven shaft 700 and coaxially fixed to the first driven shaft 700. A control plate 710 nested outside the first driven shaft 700 and rotatably connected to the first driven shaft 700 is fixed on the support 610. A chute 711 is formed on the control plate 710. A moving block 712 is slidably connected to the chute 711. The moving block 712 extends out of the chute 711. A connecting block 713 is fixed to the portion of the moving block 712 extending out of the chute 711. A strip-shaped groove 714 is formed on the swing rod 614. One side of the connecting block 713 extends into the strip-shaped groove 714 and is slidably connected to the strip-shaped groove 714. The other side is nested with two oppositely arranged and alternately arranged arc-shaped plates 715. An ear plate 716 is hingedly connected to the end of the arc-shaped plate 715 away from the connecting block 713. Each ear plate 716 is fixedly connected to the adjacent connecting plate 512.

[0053] As Figure 13 and Figure 14, in order to facilitate the cleaning of the cleaning cotton cloth, two second ear seats are further arranged below the processing frame 100 beside the first support 610. A second driven shaft 800 rotatably connected to the second ear seats penetrates between the two second ear seats. A cleaning roller 810 coaxially fixed to the second driven shaft 800 is nested on the second driven shaft 800. A number of uniformly arranged beating rods 811 are clamped and connected to the circumferential outer wall of the cleaning roller 810.

[0054] As Figure 13 and Figure 14 , both ends of the first driven shaft 700 penetrate through the first ear seat. A driving gear 900 coaxially fixed to the first driven shaft 700 is nested on the part of the first driven shaft 700 that penetrates through the first ear seat.

[0055] As Figure 13 and Figure 14 , both ends of the second driven shaft 800 penetrate through the second ear seat. A driven gear 910 rotatably connected to the second driven shaft 800 is nested on one end of the second driven shaft 800 that penetrates through the second ear seat. A rack 912 is further arranged below the processing frame 100 below the driving gear 900 and the driven gear 910. The rack 912 meshes with the driving gear 900 and the driven gear 910.

[0056] Working principle: The composite packaging film 200 passes through two conveyor rollers 110 from the flattening horizontal shaft 313 far away from the servo motor 340 to the flattening horizontal shaft 313 close to the servo motor 340. The processing guide frame 311 reduces the deviation of the composite packaging film 200 during movement. The ventilation holes 312 reduce the adhesion and adsorption of the composite packaging film 200 to the inner bottom wall of the processing guide frame 311 during movement. The driving servo motor 340 drives one of the flattening horizontal shafts 313 to rotate. The transmission belt 317 cooperates with the first pulley 316. The diameters of the two first pulleys 316 are different. The two flattening horizontal shafts 313 drive the soft film 315 to rotate following the rotation of the soft rubber spiral coil 314 through the soft rubber spiral coil 314. The soft rubber spiral coil 314 flattens the upper surface of the composite packaging film 200. The soft film 315 rotates following the soft rubber spiral coil 314, enabling the offset composite packaging film 200 to automatically adjust towards the center line of the processing guide frame 311. The two second pulleys 318 drive the internal rotating shaft 329 and the bottom rotating shaft 321 to rotate at the same speed respectively. Among them, the positioning sliding frame 333 strengthens the positioning effect through the positioning bolt 337 passing through the threaded hole 336 opened on the surface of the positioning mounting frame 331. The embedded welding strip 335 cooperates with the inner card slot 327 to drive the tubular sleeve shaft 322 to rotate synchronously. When the positioning collar 334 rotates with the bottom rotating shaft 321, the positioning notch 338 can cooperate with the elastic piece 324 to position the tubular sleeve shaft 322. The bottom rotating shaft 321 drives the cutting seat 323 to rotate synchronously through the tubular sleeve shaft 322. The two meshing connecting gears 328 keep the rotating speeds of the internal rotating shaft 329 and the bottom rotating shaft 321 the same and in opposite directions. When the bottom rotating shaft 321 drives the cutting seat 323 to rotate through the tubular sleeve shaft 322, the cutting head 326 contacts the inner wall far away from the sliding transverse groove 332 and remains inside the cutting seat 323. When the cutting end of the cutting head 326 moves to no longer contact the inner wall of the positioning mounting frame 331, it passes through the adjacent ventilation hole 312 and cuts the composite packaging film 200 to form a tear line. The cutting end of the cutting head 326 passes through the composite packaging film 200 and enters the inside of the extrusion capsule notch 3211. The sponge extrusion capsule 3210 positions around the tear line of the composite packaging film 200 to maintain the processing effect of the tear line of the composite packaging film 200;

[0057] In the initial state, the cleaning plate 513 is unfolded and located beside the cleaning roller 810. When the cutting head 326 finishes cutting and is about to rotate to the lower side of the positioning mounting bracket 331, the air cylinder 615 is opened. Powered by the air cylinder 615, the slider 612 fixed to the extended end of the air cylinder 615 moves in the slideway 611. The movement of the slider 612 drives the connecting rod 613 hinged to the slider 612 to move. The movement of the connecting rod 613 drives the swing rod 614 hinged to the connecting rod 613 to rotate. The rotation of the swing rod 614 drives the long shaft 510 fixed to the swing rod 614 to rotate, and further drives the connecting ring 511 rotatably connected to the long shaft 510 to rotate. The rotation of the connecting ring 511 drives the connecting plate 512, the ear plate 716 and the cleaning plate 513 of the integrated structure with the connecting ring 511 to rotate;

[0058] The rotation of the swing rod 614 also drives the connecting block 713 slidably connected to the swing rod 614 through the strip-shaped groove 714 to move. Through the cooperation of the moving block 712 and the sliding groove 711, the sliding path of the connecting block 713 is limited. When the connecting block 713 slides to the top position of the sliding groove 711, at this time, since the distance between the top position of the sliding groove 711 and the first driven shaft 700 is greater than the distance between the bottom position of the sliding groove 711 and the first driven shaft 700, the connecting block 713 drives the two arc-shaped plates 715 to rotate, thereby driving the two cleaning plates 513 to rotate and tighten. During the tightening process, the cutting head 326 located on the lower side of the positioning mounting bracket 331 is wiped and cleaned. The cleaning plate 513 is elastic;

[0059] After the wiping is completed, the cleaning plate 513 is disconnected from the cutting head 326, and then the air cylinder 615 is opened, so that the air cylinder 615 drives the slider 612 to move in the reverse direction in the slideway 611, thereby driving the swing rod 614 to rotate in the reverse direction. During the reverse rotation of the swing rod 614, the movement of the connecting block 713 drives the two arc-shaped plates 715 to rotate. When the moving block 712 moves to the bottom position of the sliding groove 711, the two cleaning plates 513 are driven to unfold;

[0060] Meanwhile, the rotation of the swing rod 614 will drive the rotation of the first driven shaft 700 fixedly connected coaxially with the swing rod 614. The rotation of the first driven shaft 700 will drive the rotation of the driving gear 900 fixedly connected coaxially with the first driven shaft 700. The rotation of the driving gear 900 will drive the movement of the rack 912 engaged with the driving gear 900. A frame is provided outside the device, and the rack 912 is slidably connected to the frame. The movement of the rack 912 will drive the rotation of the driven gear 910 engaged with the rack 912. The rotation of the driven gear 910 will drive the rotation of the second driven shaft 800 fixedly connected coaxially with the driven gear 910, and further drive the rotation of the cleaning roller 810 fixedly connected coaxially with the second driven shaft 800. The rotation of the cleaning roller 810 will drive the rotation of a plurality of beating rods 811 to clean the unfolded cleaning plate 513. A dust collector for sucking the dirt and debris beaten off is also provided on the frame. The dust collector is of an existing structure, so it will not be described in detail here.
