Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-5 As shown, this utility model provides a technical solution for a release paper peeling device for a laminating machine, including a conveying device 1, a laminating machine 26, and a film structure. A support frame 4 is fixedly installed on one side of the top of the conveying device 1. A partition plate 24 and a reversing shaft 25 are fixedly installed inside the support frame 4. Two winding assemblies are installed on the top of the support frame 4. A dual-axis pneumatic cylinder 11 is arranged between the two winding assemblies. A support frame 3 12 is fixedly installed on the top of the support frame 4. A cutter 15 is arranged on the top of each of the two winding assemblies. A drive assembly is arranged between the two cutters 15 and the support frame 3 12.

[0023] Specifically, the membrane structure consists of a film 2 and a release paper 3 bonded together. The release paper 3 is placed on top of the film 2. After separating one end of the membrane structure, the film 2 and the release paper 3 pass through the top and bottom of the separator plate 24 respectively, so that one end of the film 2 enters the interior of the laminating machine 26 and is wound up and used by the laminating machine 26. One end of the release paper 3 passes through the bottom of the reversing shaft 25 and moves upward through the support frame 4 to the top of the support frame 4.

[0024] Each of the two winding assemblies at the top of support frame 1 4 has a support frame 2 5. Support frame 2 5 is slidably installed on the top of support frame 1 4. A drive motor 7 is fixedly inserted on one side of support frame 2 5, and a transmission gear 8 is fixedly sleeved at the output end of the drive motor 7. The driven gear 9 meshing with the transmission gear 8 has a rotating shaft 6 fixedly connected inside. The rotating shaft 6 rotates through support frame 2 5 and can rotate on its own.

[0025] Multiple guide rods 22 are fixedly connected to the outside of the rotating shaft 6. Multiple guide grooves 23 are opened inside the collecting cylinder 21. After the collecting cylinder 21 is aligned with the rotating shaft 6, the guide grooves 23 are aligned with the guide rods 22. When the collecting cylinder 21 is pushed, the collecting cylinder 21 moves to the outside of the rotating shaft 6. The rotating shaft 6 and the collecting cylinder 21 are in an interference fit state. A certain force needs to be applied to the collecting cylinder 21 before the collecting cylinder 21 will leave the outside of the rotating shaft 6. Therefore, when the rotating shaft 6 rotates, the rotating shaft 6 drives the collecting cylinder 21 to rotate through the guide rods 22.

[0026] After pressing one end of the release paper 3 to the outside of the collection cylinder 21 containing adhesive, the drive motor 7, located at one end of the rotating shaft 6 inside the collection cylinder 21, works synchronously with the laminating machine 26. The drive motor 7 drives the collection cylinder 21 to rotate through the transmission gear 8, the driven gear 9, and the rotating shaft 6. The collection cylinder 21 rolls up the release paper 3, and the laminating machine 26 pulls one end of the film 2. Under the action of the separator 24, the film 2 and the release paper 3 are separated, completing the peeling of the release paper 3 from the outside of the film 2. The peeled release paper 3 is then rolled up for subsequent use.

[0027] After the drive motor 7 operates for a period of time, the thickness of the paper roll formed by the release paper 3 wound by the collection cylinder 21 driven by the drive motor 7 increases to a preset value. Then, a new collection cylinder 21 is installed on the outside of another rotating shaft 6. After a period of time, the dual-axis pneumatic cylinder 11 fixedly installed on the top of the control support frame 4 retracts. Since the two support frames 5 are fixedly connected to the transmission bending plate 10 on the side away from the drive motor 7, the dual-axis pneumatic cylinder 11 is fixedly installed between the two transmission bending plates 10. The retraction of the dual-axis pneumatic cylinder 11 drives the two support frames 5 to move closer to each other through the two transmission bending plates 10. The new collection cylinder 21 contacts and sticks the release paper 3 to one side. Then, the dual-axis pneumatic cylinder 11 extends to reset the two support frames 5. During this process, the drive motor 7 that operates first stops working. At this time, the paper roll can rotate freely. Therefore, during the synchronous movement of the new collection cylinder 21 that sticks the release paper 3 with the support frame 5, the new collection cylinder 21 and the release paper 3 will not separate.

[0028] After the dual-axis pneumatic cylinder 11 finishes its work, the hydraulic cylinder 13 is controlled to extend. Since the bottom of the hydraulic cylinder 13 is fixedly connected to the two cutters 15, the hydraulic cylinder 13 drives the two cutters 15 to move down a certain distance through the connecting plate 14. Since the diameter of the new collecting cylinder 21 is smaller than the outer diameter of the paper roll, after the new collecting cylinder 21 sticks to the release paper 3 and resets, some of the release paper 3 will be tilted and suspended between the two collecting cylinders 21. The release paper 3 near the new collecting cylinder 21 is lower, and the release paper 3 near the paper roll is higher. One side of one of the cutters 15 is aligned with the suspended part of the release paper 3.

[0029] Subsequently, the forward and reverse motor 20 in the control drive assembly rotates forward. Since the output end of the forward and reverse motor 20, which is fixedly installed on the support frame 3 12, passes through the support frame 3 12 and is rotatably connected to the support frame 3 12, and the output end of the forward and reverse motor 20 is fixedly connected to the gear 19, the working forward and reverse motor 20 drives the gear 19 to rotate. Also, since two limit plates 16 are fixedly connected to both sides of the hydraulic cylinder 13, two of which are located at the top of the support frame 3 12 and the other two are located at the bottom of the support frame 3 12, and the hydraulic cylinder 13 passes through the guide groove 17 opened at the top of the support frame 3 12, under the action of the four limit plates 16, the hydraulic cylinder 13 can only move along the trajectory limited by the guide groove 17.

[0030] One of the limiting plates 16 is fixedly connected to a rack 18 that meshes with a gear 19. So the rotating gear 19 drives the hydraulic cylinder 13 to move through the rack 18. The hydraulic cylinder 13 drives the cutter 15 to move. The moving cutter 15 cuts the paper roll off the release paper 3. After a period of time, the staff can pull the paper roll and the collection cylinder 21 inside the paper roll out from the outside of the rotating shaft 6. The release paper 3 can be recycled quickly, reducing the physical labor of the staff.

[0031] Then, by controlling the drive motor 7 corresponding to the new collection cylinder 21 to continue winding the release paper 3, subsequent work can be carried out.

[0032] Finally, the hydraulic cylinder 13 retracts, the connecting plate 14 and the cutter 15 move down, the forward and reverse motor 20 reverses, and the hydraulic cylinder 13 resets.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
