Description

Technical Field

[0001] This utility model relates to the field of film tearing machine technology, and in particular to a film stretching and stacking device. Background Technology

[0002] Among existing patents, Chinese patent application number 202310155985.4 discloses an automatic film-tearing device, including a frame. Along the transport path of the sheet material to be peeled, the frame is equipped with: a feeding conveyor mechanism located at the inlet of the frame for transporting the sheet material to be peeled to a film-tearing mechanism; and an output conveyor mechanism located at the outlet of the frame for discharging the sheet material after the protective film has been peeled off. The film-tearing mechanism is located between the feeding conveyor mechanism and the output conveyor mechanism, and is used to peel off the protective film covering both sides of the sheet material. The system includes: a film clamping mechanism, positioned above or below the film tearing mechanism, for removing the separated protective film; and a control system, electrically connected to and controlling the operation of the board feeding mechanism, the board discharging mechanism, the film tearing mechanism, and the film clamping mechanism. The film clamping mechanism comprises a Z-axis film clamping assembly and an X-axis film clamping assembly. The Z-axis film clamping assembly is perpendicular to the film tearing mechanism and is used to clamp the protective film vertically. The X-axis film clamping assembly is parallel to the film tearing mechanism and is used to clamp the protective film horizontally and place it into a storage frame. While the film clamping mechanism disclosed in this patent document can achieve Z-axis and X-axis film pulling of the film material (protective film) and place the film material in a storage frame, there is a certain height distance between the storage frame and the X-axis film clamping assembly. Therefore, after the X-axis film clamping assembly releases the film material, it falls freely into the storage frame. The stability and positional accuracy of the film material falling into the storage frame are poor. Furthermore, during the falling process, the film material is prone to floating or bending, making it impossible to place the film material neatly in the storage frame. Therefore, the defects are quite obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a film stacking device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A film stacking device includes a transverse drive mechanism, a transverse film clamping mechanism mounted on the moving end of the transverse drive mechanism, a longitudinal drive mechanism located on one side of the transverse drive mechanism, a longitudinal film clamping mechanism mounted on the moving end of the longitudinal drive mechanism, a lifting drive mechanism located on the other side of the transverse drive mechanism, and a stacking platform mounted on the lifting end of the lifting drive mechanism. The longitudinal film clamping mechanism is movably disposed between the transverse film clamping mechanism and the lifting drive mechanism, and the stacking platform is lifted above or below the transverse film clamping mechanism. The transverse drive mechanism is used to drive the transverse film clamping mechanism to move closer to or away from the longitudinal film clamping mechanism, and the longitudinal drive mechanism is used to drive the longitudinal film clamping mechanism to move longitudinally.

[0005] Furthermore, the transverse film clamping mechanism includes a movable seat mounted on the movable end of the transverse drive mechanism and a transverse film clamping module mounted on the movable seat. The transverse film clamping module includes a transverse film clamping driver mounted on the movable seat, two transverse film clamping plates respectively mounted on the two output ends of the transverse film clamping driver and arranged opposite to each other, and a plurality of film clamping blocks protruding from the front of the transverse film clamping plates. The plurality of film clamping blocks are spaced apart. The transverse film clamping driver is used to drive the two transverse film clamping plates to move closer or further away from each other. The film clamping end of the longitudinal film clamping mechanism is provided with a plurality of clearance openings. The plurality of clearance openings are respectively arranged in correspondence with the plurality of film clamping blocks, and the film clamping blocks can extend into the clearance openings.

[0006] Furthermore, the transverse membrane plate is provided with an air passage, the interior of the membrane block is provided with an air cavity communicating with the air passage, and the membrane surface of the membrane block is provided with an air blowing hole communicating with the air cavity.

[0007] Furthermore, the longitudinal film clamping mechanism also includes a film pushing arm that is movably disposed on the sides of the two transverse film clamping plates and a film pushing driver mounted on the movable seat for driving the film pushing arm to reciprocate.

[0008] Furthermore, there are two film-pushing arms, which are located on both sides of the transverse clamping plate.

[0009] Furthermore, a connecting rod is connected between the two film-pushing arms, and the drive end of the film-pushing driver is connected to the connecting rod.

[0010] Furthermore, the film pushing arm has a guide groove, the moving seat is equipped with a guide rod, the guide rod passes through the guide groove, and the guide rod slides in conjunction with the guide groove; the film clamping block is L-shaped, and the guide rod is located between two transverse film clamping plates.

[0011] Furthermore, there are multiple transverse lamination modules, with a spacing between them. The stacking platform has multiple clearance slots, and each transverse lamination module is correspondingly set with one of the clearance slots. The clearance slots provide clearance space for the transverse lamination modules.

[0012] Furthermore, the longitudinal film clamping mechanism includes a lifting seat mounted on the moving end of the longitudinal drive mechanism and a longitudinal film clamping module mounted on the lifting seat. The longitudinal film clamping module includes a longitudinal film clamping driver mounted on the lifting seat, a fixed plate mounted on the lifting seat, a plurality of L-shaped clamping blocks spaced apart at the bottom of the fixed plate, a movable clamping plate mounted on the driving end of the longitudinal film clamping driver and located on one side of the fixed plate, and a plurality of movable clamping blocks spaced apart at the bottom of the movable clamping plate. The plurality of movable clamping blocks are respectively arranged in one-to-one correspondence with the plurality of L-shaped clamping blocks. The movable clamping blocks are located above the horizontal part of the L-shaped clamping blocks. The longitudinal film clamping driver is used to drive the movable clamping plate to move the movable clamping blocks closer to or away from the horizontal part of the L-shaped clamping blocks. The clearance opening is located between two adjacent L-shaped clamping blocks.

[0013] Furthermore, the film stacking device also includes a front limiting guide roller group, a rear limiting guide roller group, and a moving drive mechanism. The longitudinal film clamping mechanism is located between the front limiting guide roller group and the rear limiting guide roller group. The front limiting guide roller group is located on the side of the longitudinal film clamping mechanism closer to the transverse film clamping mechanism. The rear limiting guide roller group is mounted on the moving end of the moving drive mechanism. The moving drive mechanism is used to drive the rear limiting guide roller group closer to or away from the front limiting guide roller group.

[0014] The beneficial effects of this utility model are as follows: In practical applications, initially, the longitudinal clamping mechanism is in its lowest position, and the clamping end of the longitudinal clamping mechanism is in an open state. After one end of the film material enters the clamping end of the longitudinal clamping mechanism, the clamping end of the longitudinal clamping mechanism clamps one end of the film material. Then, the longitudinal movement drive mechanism drives the longitudinal clamping mechanism, along with the clamped film material, to move upward. The film material bends upward around the bottom of the front limit guide roller group. When the longitudinal clamping mechanism moves upward to a position higher than the top surface of the rear limit guide roller group, the movement... The drive mechanism moves the rear limit guide roller group closer to the front limit guide roller group, causing the front and rear limit guide roller groups to roll into contact with both sides of the film material. This guides the film material upward, preventing it from floating or bending during its upward movement and ensuring a smooth and straight upward motion. When the longitudinal clamping mechanism clamps the film material and raises it to a preset height, the transverse drive mechanism moves the transverse clamping mechanism closer to the clamping end of the longitudinal clamping mechanism until the transverse clamping mechanism clamps the film. After the film material is clamped by the longitudinal clamping mechanism, the clamping end of the longitudinal clamping mechanism releases the film material. Then, the transverse drive mechanism drives the transverse clamping mechanism, along with the clamped film material, to move away from the longitudinal clamping mechanism until the film material is pulled onto the stacking platform. The stacking platform supports the film material, at which point the transverse clamping mechanism releases the film material, allowing the film material to be stably stacked on the stacking platform or on the film material on the stacking platform. After the film material on the longitudinal clamping mechanism is clamped away by the transverse clamping mechanism, the movement drive mechanism drives the rear limit guide roller group to move away from the front limit guide roller group and reset. The longitudinal drive mechanism drives the longitudinal clamping mechanism to move down and reset. The above film pulling action is repeated so that the film material is stacked one sheet at a time on the stacking platform. When each additional sheet of film material is added to the stacking platform, the lifting drive mechanism drives the stacking platform to descend by the displacement of one sheet of film material to ensure that the film material can be stably stacked on the stacking platform. When the number of film materials stacked on the stacking platform reaches a preset value, a stack of neatly stacked film materials can be removed from the stacking platform, thus facilitating the collection and recycling of the film material. This invention enables the stretching of membrane material and the stable and orderly stacking and collection of membrane material, facilitating the recycling of membrane material.

Detailed Implementation To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0021] like Figures 1 to 5 As shown, the present invention provides a film-stretching and stacking device for a film-tearing machine, which includes a transverse drive mechanism 1, a transverse film clamping mechanism 2 installed at the moving end of the transverse drive mechanism 1, a longitudinal drive mechanism 3 located on one side of the transverse drive mechanism 1, a longitudinal film clamping mechanism 4 installed at the moving end of the longitudinal drive mechanism 3, a lifting drive mechanism 5 located on the other side of the transverse drive mechanism 1, and a stacking platform 6 installed at the lifting end of the lifting drive mechanism 5. The longitudinal film clamping mechanism 4 is movably disposed between the transverse film clamping mechanism 2 and the lifting drive mechanism 5, and the stacking platform 6 is lifted above or below the transverse film clamping mechanism 2. The transverse drive mechanism 1 is used to drive the transverse film clamping mechanism 2 to move closer to or away from the longitudinal film clamping mechanism 4, and the longitudinal drive mechanism 3 is used to drive the longitudinal film clamping mechanism 4 to move longitudinally. Specifically, the film stacking device also includes a front limiting guide roller group 29, a rear limiting guide roller group 30, and a moving drive mechanism 31. The longitudinal film clamping mechanism 4 is located between the front limiting guide roller group 29 and the rear limiting guide roller group 30. The front limiting guide roller group 29 is located on the side of the longitudinal film clamping mechanism 4 closer to the transverse film clamping mechanism 2. The rear limiting guide roller group 30 is installed on the moving end of the moving drive mechanism 31. The moving drive mechanism 31 is used to drive the rear limiting guide roller group 30 to move closer to or away from the front limiting guide roller group 29.

[0022] In practical applications, this utility model has two working states; the first working state: initially, the stacking platform 6 is raised and lowered below the transverse clamping mechanism 2, the longitudinal clamping mechanism 4 is in the lowest position, and the clamping end of the longitudinal clamping mechanism 4 is in the open clamping state. After one end of the film material enters the clamping end of the longitudinal clamping mechanism 4, the clamping end of the longitudinal clamping mechanism 4 clamps one end of the film material. Then, the longitudinal movement drive mechanism 3 drives the longitudinal clamping mechanism 4 and the clamped film material to move upward. The film material bends around the bottom of the front limit guide roller group 29 and moves upward. When the longitudinal clamping mechanism 4 moves towards... When the material moves upward to a position higher than the top surface of the rear limit guide roller group 30, the moving drive mechanism 31 drives the rear limit guide roller group 30 to move closer to the front limit guide roller group 29, so that the front limit guide roller group 29 and the rear limit guide roller group 30 respectively roll into contact with both sides of the film material to guide the upward movement of the film material, preventing the film material from floating or bending during the upward movement, and ensuring that the film material can move upward smoothly and straight. When the longitudinal clamping mechanism 4 clamps the film material and rises to the preset height, the transverse drive mechanism 1 drives the transverse clamping mechanism 2 to move closer to the clamping end of the longitudinal clamping mechanism 4. After the transverse clamping mechanism 2 clamps the film material of the longitudinal clamping mechanism 4, the clamping end of the longitudinal clamping mechanism 4 releases the film material. Then, the transverse drive mechanism 1 drives the transverse clamping mechanism 2, along with the clamped film material, to move away from the longitudinal clamping mechanism 4 until the film material is pulled onto the stacking platform 6. The stacking platform 6 supports the film material, at which point the transverse clamping mechanism 2 releases the film material, allowing the film material to be stably stacked on the stacking platform 6 or on the film material on the stacking platform 6. After the film material on the longitudinal clamping mechanism 4 is clamped away by the transverse clamping mechanism 2, the movement drive mechanism 31 drives the rear limit guide roller. Group 30 moves away from the front limit guide roller group 29 and resets, and the longitudinal movement drive mechanism 3 drives the longitudinal clamping film mechanism 4 to move down and reset; repeat the above film pulling action so that the film material is stacked one by one on the stacking platform 6. When each additional film material is added to the stacking platform 6, the lifting drive mechanism 5 drives the stacking platform 6 to descend by the displacement of one film material to ensure that the film material can be stably stacked on the stacking platform 6; when the number of film materials stacked on the stacking platform 6 reaches the preset number value, a stack of neatly stacked film materials can be removed from the stacking platform 6, thereby facilitating the collection and recycling of the film material.

[0023] The second working state: Initially, the stacking platform 6 is located above the transverse clamping mechanism 2, and a film storage frame is provided below the transverse clamping mechanism 2. The stacking platform 6 has a clearance groove 21, which allows the transverse clamping mechanism 2 to pass through. The longitudinal clamping mechanism 4 is in the lowest position, and the clamping end of the longitudinal clamping mechanism 4 is in the open clamping state. After one end of the film material enters the clamping end of the longitudinal clamping mechanism 4, the clamping end of the longitudinal clamping mechanism 4 clamps one end of the film material. Then, the longitudinal drive mechanism 3 drives the longitudinal clamping mechanism 4 and the clamped part to move together. The film material moves upward, bending around the bottom of the front limiting guide roller group 29. When the longitudinal clamping mechanism 4 moves upward to a position higher than the top surface of the rear limiting guide roller group 30, the moving drive mechanism 31 drives the rear limiting guide roller group 30 to move closer to the front limiting guide roller group 29. This causes the front limiting guide roller group 29 and the rear limiting guide roller group 30 to roll into contact with both sides of the film material, guiding the upward movement of the film material and preventing it from floating or bending during the upward movement. This ensures that the film material can move upward smoothly and straight. When the longitudinal clamping mechanism 4 clamps the film material and rises to a preset height, the transverse drive mechanism 1 drives the transverse clamping mechanism 2 to move closer to the clamping end of the longitudinal clamping mechanism 4 until the clamping end of the transverse clamping mechanism 2 clamps the film material of the longitudinal clamping mechanism 4. Then, the clamping end of the longitudinal clamping mechanism 4 releases the film material. Next, the transverse drive mechanism 1 drives the transverse clamping mechanism 2, along with the clamped film material, to move away from the longitudinal clamping mechanism 4 until the film material is pulled to the bottom of the stacking platform 6. At the same time, the transverse clamping mechanism 2 releases the film material and simultaneously raises and lowers. The drive mechanism 5 quickly drives the stacking platform 6 to move downwards towards the membrane storage frame, so that the clearance groove 21 of the stacking platform 6 passes through the transverse membrane clamping mechanism 2 and quickly presses the membrane material into the membrane storage frame, so that the membrane materials stacked in the membrane storage frame are tightly fitted together, preventing the membrane materials from being loose, and allowing the membrane materials to be stably stacked in the membrane storage frame; after each piece of membrane material is pressed down into the membrane storage frame, the stacking platform 6 will rise and return to above the transverse membrane clamping mechanism 2, so as to press down the next piece of membrane material; when the membrane storage frame is full of membrane material, a stack of membrane material can be removed.

[0024] This invention enables the stretching of membrane material and the stable and orderly stacking and collection of membrane material, ensuring that the stacked membrane material does not become loose and facilitating its recycling.

[0025] Specifically, the moving drive mechanism 31 can be a cylinder that is tilted downwards, and the rear limit guide roller group 30 is mounted on the piston rod of the cylinder. The piston rod of the cylinder extends to drive the rear limit guide roller group 30 to tilt downwards and approach the front limit guide roller group 29.

[0026] In this embodiment, the transverse film clamping mechanism 2 includes a movable seat 7 mounted on the movable end of the transverse drive mechanism 1 and a transverse film clamping module 8 mounted on the movable seat 7. The transverse film clamping module 8 includes a transverse film clamping driver 9 mounted on the movable seat 7, two transverse film clamping plates 10 respectively mounted on the two output ends of the transverse film clamping driver 9 and arranged opposite to each other, and a plurality of film clamping blocks 11 protruding from the front surface of the transverse film clamping plates 10. The plurality of film clamping blocks 11 are spaced apart. The transverse film clamping driver 9 is used to drive the two transverse film clamping plates 10 to move closer or further away from each other. The clamping end of the longitudinal film clamping mechanism 4 is provided with a plurality of clearance openings 12. The plurality of clearance openings 12 are respectively arranged in a one-to-one correspondence with the plurality of film clamping blocks 11, and the film clamping blocks 11 can extend into the clearance openings 12. Specifically, the transverse film clamping driver 9 can be a finger cylinder.

[0027] In practical applications, the transverse drive mechanism 1 drives the moving seat 7, along with the transverse clamping module 8, to move closer to or away from the longitudinal clamping mechanism 4. Specifically, during the process of the longitudinal clamping mechanism 4 pulling the film upward to a preset height position, the transverse clamping driver 9 drives the two transverse clamping plates 10 to move away from each other, causing several clamping blocks 11 on the two transverse clamping plates 10 to open up to each other. The transverse drive mechanism 1 then drives the moving seat 7, along with the open transverse clamping module 8, to move to the clamping position, causing the clamping blocks 11 on the transverse clamping plates 10 to move into the clearance opening 12. The film clamped by the longitudinal clamping mechanism 4 is located between the clamping blocks 11 of the two transverse clamping plates 10. The transverse clamping driver 9 drives the two transverse clamping plates 10 to move closer to each other, so that the clamping blocks 11 on the two transverse clamping plates 10 close together and clamp the film. At this time, the clamping end of the longitudinal clamping mechanism 4 releases the film. Then, the transverse drive mechanism 1 drives the moving seat 7 to move away from the longitudinal clamping mechanism 4, along with the transverse clamping module 8 and the film. When the film moves to the preset position of the stacking platform 6, the stacking platform 6 supports the film. The transverse clamping driver 9 drives the two transverse clamping plates 10 to move away from each other, so that the clamping blocks 11 on the two transverse clamping plates 10 open to release the film. The film is stably stacked on the stacking platform 6 or the stacking platform 6 presses the film down into the storage frame.

[0028] In this embodiment, the transverse membrane plate 10 is provided with a ventilation channel 13, and the interior of the membrane block 11 is provided with an air cavity 14 communicating with the ventilation channel 13. The membrane surface of the membrane block 11 is provided with an air blowing hole 15 communicating with the air cavity 14. The ventilation channel 13 is connected to a blower mechanism, and the blower mechanism introduces positive pressure gas into the ventilation channel 13. After the several clamping blocks 11 on the two transverse clamping plates 10 are opened, if static electricity or negative pressure is generated between the membrane material and the clamping blocks 11, the membrane material will adhere to the clamping blocks 11 or move with the clamping blocks 11, causing the membrane material to shift. This will not only affect the neat stacking of the membrane material, but also affect the normal operation of the transverse clamping mechanism 2. In order to overcome the above problems, when the several clamping blocks 11 on the two transverse clamping plates 10 are opened, the blower mechanism introduces positive pressure gas into the ventilation channel 13. The positive pressure gas flows along the ventilation channel 13 into the air chamber 14 and forms a positive pressure airflow. The positive pressure airflow blows out from the blow hole 15. This positive pressure airflow blows the membrane material away from the clamping blocks 11, so as to achieve stable separation of the membrane material from the clamping blocks 11. This can improve the stability and neatness of the membrane material stacked on the stacking platform 6 or the stacking platform 6 pressing the membrane material into the storage frame.

[0029] In this embodiment, the longitudinal clamping mechanism 4 further includes a pusher arm 16 movably disposed on the sides of the two transverse clamping plates 10 and a pusher driver 17 mounted on the movable seat 7 for driving the pusher arm 16 to reciprocate. Specifically, the pusher driver 17 can be a cylinder. When several clamping blocks 11 on the two transverse clamping plates 10 are opened, the pusher driver 17 drives the pusher arm 16 to translate in a direction closer to the longitudinal clamping mechanism 4. The translated pusher arm 16 pushes the film material away from the clamping blocks 11 to achieve stable separation of the film material from the clamping blocks 11. Of course, depending on the user's different usage requirements, the method of positive pressure airflow blowing the film material away from the clamping blocks 11 and the method of pusher arm 16 pushing the film material away from the clamping blocks 11 can be used selectively, or they can be used simultaneously.

[0030] In this embodiment, there are two film-pushing arms 16, which are located on both sides of the transverse clamping plate 10. The two film-pushing arms 16 push the film material away from several clamping blocks 11, which improves the stability of film pushing, makes the film material uniformly stressed, and makes it less prone to bending.

[0031] In this embodiment, a connecting rod 18 connects the two film-pushing arms 16, forming a U-shaped or U-shaped structure with the connecting rod 18 and the two film-pushing arms 16. The driving end of the film-pushing driver 17 is connected to the connecting rod 18. This structural design facilitates the film-pushing driver 17 to drive the connecting rod 18 to synchronously translate the two film-pushing arms 16.

[0032] In this embodiment, the film-pushing arm 16 has a guide groove 19, and the movable seat 7 is equipped with a guide rod 20. The guide rod 20 passes through the guide groove 19 and slides in conjunction with the guide groove 19. During the reciprocating movement of the film-pushing arm 16, the sliding contact between the guide rod 20 and the guide groove 19 improves the stability of the movement of the film-pushing arm 16.

[0033] Specifically, the membrane clamping block 11 is L-shaped, and the guide rod 20 is located between the two transverse membrane clamping plates 10. This structural design makes the structure of the membrane clamping block 11, the transverse membrane clamping plates 10 and the guide rod 20 compact and requires little space.

[0034] In this embodiment, there are multiple transverse film-clamping modules 8, spaced apart. The stacking platform 6 has multiple clearance slots 21, with each transverse film-clamping module 8 corresponding to one of the clearance slots 21. The clearance slots 21 provide clearance space for the transverse film-clamping modules 8. This structural design is beneficial for stretching film materials with a relatively large width, and the transverse film-clamping modules 8 will not collide or interfere with the stacking platform 6.

[0035] In this embodiment, the longitudinal clamping mechanism 4 includes a lifting seat 22 mounted on the moving end of the longitudinal drive mechanism 3 and a longitudinal clamping module 23 mounted on the lifting seat 22. The longitudinal clamping module 23 includes a longitudinal clamping driver 24 mounted on the lifting seat 22, a fixed plate 25 mounted on the lifting seat 22, a plurality of L-shaped clamping blocks 26 spaced apart at the bottom of the fixed plate 25, a movable clamping plate 27 mounted on the driving end of the longitudinal clamping driver 24 and located on one side of the fixed plate 25, and a plurality of movable clamping blocks 28 spaced apart at the bottom of the movable clamping plate 27. The plurality of movable clamping blocks 28 are respectively arranged in a one-to-one correspondence with the plurality of L-shaped clamping blocks 26. The movable clamping blocks 28 are located above the horizontal part of the L-shaped clamping blocks 26. The longitudinal clamping driver 24 is used to drive the movable clamping plate 27 to move the movable clamping blocks 28 closer to or away from the horizontal part of the L-shaped clamping blocks 26. The clearance opening 12 is located between two adjacent L-shaped clamping blocks 26. Specifically, the longitudinal clamping driver 24 can be a vertically downward cylinder.

[0036] In practical applications, the longitudinal clamping driver 24 drives the moving clamping plate 27 and multiple moving clamping blocks 28 to move upward, so that the multiple moving clamping blocks 28 and multiple L-shaped clamping blocks 26 are in the open state. At this time, one end of the film material moves into the space between the moving clamping block 28 and the L-shaped clamping block 26. Then, the longitudinal clamping driver 24 drives the moving clamping plate 27 and multiple moving clamping blocks 28 to move downward, so that the multiple moving clamping blocks 28 and multiple L-shaped clamping blocks 26 close and clamp the film material. Then, the longitudinal movement drive mechanism 3 drives the lifting seat 22 to move the longitudinal clamping module 23 and the film material upward.

[0037] Specifically, there are multiple longitudinal clamping modules 23, and each longitudinal clamping module 23 is respectively set in correspondence with a multiple transverse clamping module 8; this structural design can clamp and stretch a wide film material.

[0038] In another embodiment, when the stacking platform 6 is located below the transverse film clamping mechanism 2, the film stacking device further includes a lifting drive module arranged parallel to the lifting drive mechanism 5 and a lower pressure platform installed at the lifting end of the lifting drive module. The lower pressure platform has a through groove that allows the transverse film clamping mechanism 2 to pass through. The lower pressure platform and the stacking platform 6 are arranged vertically opposite each other. Initially, the lower pressure platform is located above the transverse film clamping mechanism 2.

[0039] In practical applications, when the transverse clamping mechanism 2 clamps the film material and moves it above the stacking platform 6, the transverse clamping mechanism 2 releases the film material, and at the same time, the lifting drive module drives the lower pressure platform to move downward quickly, so that the lower pressure platform quickly presses the film material onto the stacking platform 6, making the stacked film materials on the stacking platform 6 close together, avoiding the loosening of the stacked film materials, and enabling the film materials to be stably stacked on the stacking platform 6; after the lower pressure platform presses the film material onto the stacking platform 6, the lifting drive module drives the lower pressure platform to rise and reset, so that the lower pressure platform is above the transverse clamping mechanism 2; for each additional piece of film material added to the stacking platform 6, the lifting drive mechanism 5 can drive the stacking platform 6 to descend by the displacement of one piece of film material, so that the stacking platform 6 can stably stack the film materials.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
