[0002] Polycarbonate sheets (PC sheets) are high-performance sheet materials made primarily from polycarbonate resin through processes such as extrusion and injection molding. They possess a range of excellent properties including lightweight, light transmission, impact resistance, and weather resistance, making them widely used in construction, transportation, electronics, advertising, and many other fields. However, with increasing demands for the surface quality of PC sheets, lamination protection has become an indispensable part of the production process. Manual lamination is prone to problems such as air bubbles, film misalignment, and uneven pressing leading to localized poor adhesion. Therefore, an automated polycarbonate sheet lamination device is needed.

[0003] The automatic polycarbonate sheet laminating device applies protective films such as PE and PET to the surface of PC sheets, preventing damage during transportation and processing, and delaying yellowing caused by ultraviolet rays. However, in previous technologies, traditional manual cutting required cutting with a utility knife after lamination, which was not only inefficient but also posed a risk of hand cuts. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 3 and Figure 4An embodiment of this utility model provides an automatic polycarbonate sheet coating device, including a workbench 1 and a limiting plate 15. A motor 6 is fixedly connected inside the limiting plate 15. A rotating column 7 is fixedly installed at the output end of the motor 6. A sliding groove 8 is opened inside the rotating column 7. A sliding shaft 9 is installed inside the rotating column 7. The outer wall of the sliding shaft 9 is slidably connected to the inner wall of the sliding groove 8. A sliding block 10 is rotatably connected to the outer wall of the sliding shaft 9. A support column 11 is slidably connected inside the sliding block 10. Both ends of the support column 11 are fixedly connected to the outer wall of the limiting plate 15. A spring 12 is sleeved on the outer wall of the support column 11.

A support assembly is provided on the upper surface of the workbench 1.

[0026] Specifically, the limiting plate 15 serves to fix the position of the motor 6. The starting motor 6 drives the rotating column 7 to rotate. The rotation of the rotating column 7 causes the sliding shaft 9 to slide through the sliding groove 8 inside it. The sliding of the sliding shaft 9 causes the sliding block 10 to slide on the outer wall of the support column 11. At the same time, the limiting plate 15 fixes the position of the support column 11. The movement of the sliding block 10 causes the connecting column 13 to slide synchronously under the support of the limiting plate 15. The movement of the connecting column 13 can drive the cutting blade 17 to move synchronously through the connecting frame 14. The connecting frame 14 fixes the position of the cutting blade 17, thereby driving the cutting blade 17 to move back and forth to achieve the effect of automatic film cutting. At the same time, the spring 12 sleeved on the outer wall of the support column 11 acts as a buffer.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The support assembly includes a support platform 5, the lower surface of which is fixedly connected to the upper surface of the workbench 1, the lower surface of the limiting plate 15 is fixedly connected to the upper surface of the support platform 5, a conveyor 2 is provided on the upper surface of the workbench 1, a support frame 3 is fixedly connected to the upper surface of the workbench 1, a support rod 33 is rotatably connected inside the support frame 3, a membrane 4 is provided on the outer wall of the support rod 33, and a limiting rod 16 is fixedly connected inside the support frame 3.

[0028] Specifically, the workbench 1 serves to fix the position of the support platform 5, the support platform 5 serves to fix the position of the limiting plate 15, and the workbench 1 serves to stably place the conveyor 2. The conveyor 2 is existing technology and serves to automatically move items. The polycarbonate sheet can be moved by placing it on the conveyor belt of the conveyor 2.

The workbench 1 serves to fix the position of the support frame 3, the support frame 3 serves to fix the positions of the support rod 33 and the limiting rod 16, the support rod 33 serves to support the membrane 4, and the limiting rod 16 serves to stably stretch the membrane.

[0029] Reference Figure 1 , Figure 5 and Figure 6 The upper surface of the workbench 1 is fixedly connected to a support platform 2 18, the upper surface of the support platform 2 18 is fixedly connected to a support plate 19, and the outer wall of the support plate 19 is fixedly connected to a limit platform 30; the upper surface of the support plate 19 is fixedly connected to a fixing plate 1 20, and the inside of the fixing plate 1 20 is rotatably connected to a support block 21; the outer wall of the support block 21 is fixedly connected to a hydraulic cylinder 22, the output end of the hydraulic cylinder 22 is fixedly connected to a connecting shaft 1 23, and the outer wall of the connecting shaft 1 23 is rotatably connected to a rotating plate 24;

[0030] Specifically, the workbench 1 serves to fix the position of the second support platform 18, the second support platform 18 serves to fix the position of the support plate 19, the support plate 19 serves to fix the position of the limiting platform 30, and the support plate 19 serves to fix the position of the first fixed plate 20. Thus, the first fixed plate 20 can rotate the stabilizing support block 21, and the support block 21 serves to stabilize the position of the hydraulic cylinder 22. By starting the hydraulic cylinder 22 to move back and forth, the rotating plate 24 is driven by the connecting shaft 23 to rotate under the support of the rotating shaft 25.

[0031] Reference Figure 5 and Figure 6 The rotating plate 24 is rotatably connected to a rotating shaft 25, and a fixing plate 26 is fixedly connected to the outer wall of the rotating shaft 25. The outer wall of the fixing plate 26 is fixedly connected to the outer wall of the limiting platform 30. The rotating plate 24 is fixedly connected to a traction shaft 27, and a traction plate 28 is slidably connected to the outer wall of the traction shaft 27. A connecting plate 31 is fixedly connected to the outer wall of the traction plate 28. A sliding shaft 32 is fixedly connected to the lower surface of the connecting plate 31. The outer wall of the sliding shaft 32 is slidably connected to the inside of the fixing plate 20. A pressing plate 29 is fixedly connected to the lower surface of the sliding shaft 32.

[0032] Specifically, the fixed plate 26 serves to fix the position of the rotating shaft 25, and the limiting platform 30 serves to fix the position of the fixed plate 26. Then, the rotation of the rotating plate 24 drives the traction shaft 27 to slide inside the traction plate 28, thereby driving the traction plate 28 to reciprocate. Then, the traction plate 28 can drive the sliding shaft 32 to reciprocate under the support of the limiting platform 30 through the connecting plate 31. Thus, the movement of the sliding shaft 32 can drive the pressing plate 29 to reciprocate. The pressing plate 29 can press the coated polycarbonate plate smoothly, thereby ensuring the consistency of the overall coating position.

[0033] Working principle: In use, the polycarbonate sheet to be coated is first placed on the conveyor 2. After the coating operation is completed by the film body 4 and the limiting rod 16, the motor 6 is started to drive the rotating column 7 to rotate. The rotation of the rotating column 7 can drive the sliding shaft 9 to slide through the sliding groove 8 inside. Thus, the sliding shaft 9 can drive the sliding block 10 to reciprocate under the support of the support column 11. Then, the movement of the sliding block 10 can drive the connecting column 13 to move synchronously under the support of the limiting plate 15. Thus, the movement of the connecting column 13 can drive the cutting blade 17 to reciprocate on the surface of the coated polycarbonate sheet through the connecting frame 14. The reciprocating motion of the cutting blade 17 achieves precise and fast cutting of the protective film.

[0034] After cutting, the hydraulic cylinder 22 can be activated according to the thickness of the polycarbonate sheet or film. The reciprocating movement of the hydraulic cylinder 22 can drive the rotating plate 24 to rotate under the support of the limiting plate 15 via the connecting shaft 23. The rotation of the rotating plate 24 can drive the traction shaft 27 to slide within the groove of the traction plate 28. The limiting movement of the traction shaft 27 can drive the traction plate 28 to move horizontally. The movement of the support platform 18 can drive the sliding shaft 32 to reciprocate under the support of the limiting platform 30 via the connecting plate 31. This causes the sliding shaft 32 to drive the pressing plate 29 to reciprocate, thereby applying pressure to polycarbonate sheets of different thicknesses to ensure complete adhesion to the film.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
