[0035] Reference Figure 2-Figure 3Hydraulic cylinders 2 are installed on both sides of the front and rear inner walls of the bottom end of the operating table 1. During the winding process, the hydraulic cylinder 2 is started, and the driving end of the hydraulic cylinder 2 is fixedly connected to a limit plate 3. The inner wall of the limit plate 3 is slidably connected to a connecting plate 4. Driven by the hydraulic cylinder 2, the connecting plate 4 will slide on the inner wall of the limit plate 3. A support frame 5 is fixedly connected to the top of the limit plate 3. A connecting column 6 is fixedly connected to the middle of the support frame 5. The bottom of the connecting column 6 is rotatably connected to a limit block 7. A guide groove 8 is provided on one side of the outside of the connecting plate 4. As the connecting plate 4 moves, the limit block 7 will be driven to slide inside the guide groove 8.

[0036] Two moving bins 9 are fixedly connected inside the connecting plate 4, and a telescopic component is arranged inside the moving bin 9, and the telescopic component includes a connecting column 10, a spring 11 and a stopper 12. The limit block 7 will squeeze the stopper 12 during the sliding process, and a connecting column 10 is fixedly connected to one side of the inside of the moving bin 9, and the stopper 12 slides toward the inside of the moving bin 9 under force, and a spring 11 is sleeved on the outside of the connecting column 10, and one end of the spring 11 is fixedly connected to one side of the inside of the moving bin 9, and the other end of the spring 11 is fixedly connected to the side of the stopper 12 close to the spring 11.

[0037] Reference Figure 1 and Figure 4 A cooling roller 14 is provided inside the cooling box 13, and the cooling roller 14 can cool the protective film. Fans 23 are fixedly connected to the left and right sides of the top of the cooling box 13. Starting the fans 23 at the same time can assist the cooling of the cooling roller 14. One end of the cooling roller 14 is placed inside one side of the cooling box 13. A plurality of card slots 15 are provided at the front and rear ends of the cooling roller 14. A plurality of fixing components are provided on the front and rear sides of the cooling box 13. The fixing components include a cavity 16, a second spring 17, a rubber column 18 and a third spring 19. At this time, the outside of the cooling roller 14 will squeeze the rubber column 18, and the rubber column 18 is forced to move toward the inside of the cavity 16.

[0038] The cavity 16 is opened inside the cooling box 13, and a spring 17 is arranged inside the cavity 16 so that the spring 17 is compressed inside the cavity 16. One end of the spring 17 is fixedly connected to a rubber column 18, and the outside of the rubber column 18 is engaged with the inner wall of the slot 15. As the cooling roller 14 moves, when the slot 15 contacts the rubber column 18, the spring 17 will generate a reaction force on the rubber column 18, so that the rubber column 18 is tightly engaged with the slot 15. Then, the other end of the cooling roller 14 is inserted into the other side of the cooling box 13 to fix the cooling roller 14, which is convenient for disassembly and maintenance of the cooling roller 14.

[0039] Reference Figure 1 and Figure 5 A cleaning assembly is provided on both sides of the cooling box 13, and the cleaning assembly includes a plurality of springs 3 19, a limit plate 20, a connecting rod 21 and a brush 22. When the protective film passes through the brush 22, the brush 22 will clean the outside of the protective film. At this time, the brush 22 will be forced to slide toward the inside of the cooling box 13, the outside of the limit plate 20 is slidably connected to the inner wall of the cooling box 13, and the outside of the connecting rod 21 is slidably connected to the inner wall of the cooling box 13. At the same time, the connecting rod 21 and the limit plate 20 are forced to slide toward the inside of the cooling box 13.

[0040] One end of spring three 19 is fixedly connected to one side of the interior of the cooling box 13. At this time, the spring three 19 is compressed inside the cooling box 13. The other end of the spring three 19 is fixedly connected to the limit plate two 20. The spring three 19 will generate a reaction force on the limit plate two 20 when it is compressed. The other side of the limit plate two 20 is fixedly connected to a connecting rod 21. The other side of the connecting rod 21 is fixedly connected to a brush 22, so that the brush 22 is in close contact with the protective film, which has a better cleaning effect, can clean the protective film, and reduce impurities on the outside of the protective film.

[0041] Working principle: first, place the operating table 1 to a suitable position, and put one end of the cooling drum 14 into one side of the cooling box 13. At this time, the outside of the cooling drum 14 will squeeze the rubber column 18, and the rubber column 18 will be forced to move toward the inside of the cavity 16, so that the spring 2 17 will be compressed inside the cavity 16. As the cooling drum 14 moves, when the slot 15 contacts the rubber column 18, the spring 2 17 will generate a reaction force on the rubber column 18, so that the rubber column 18 and the slot 15 are tightly engaged. Then, the other end of the cooling drum 14 is inserted into the other side of the cooling box 13 to fix the cooling drum 14. Then, the protective film on the material rack is placed into the cooling box 13, and then passed through the bottom of the cooling drum 14 and then around the top of the connecting column 6. The cooling drum 14 can cool the protective film.

[0042] At the same time, the fan 23 is started to assist the cooling roller 14 in cooling. The film is then passed through the cooling box 13 and placed on the winding shaft 25. The motor 26 is then started. Driven by the motor 26, the winding shaft 25 winds up the protective film. When the protective film passes through the brush 22, the brush 22 will clean the outside of the protective film. At this time, the brush 22 will be forced to slide toward the inside of the cooling box 13. At the same time, the connecting rod 21 and the limit plate 20 will be forced to slide toward the inside of the cooling box 13. At this time, the spring three 19 is compressed inside the cooling box 13. When compressed, the spring three 19 will generate a reaction force on the limit plate 20, so that the brush 22 is in close contact with the protective film, and the cleaning effect is better.

[0043] During the winding process, the hydraulic cylinder 2 is started. Driven by the hydraulic cylinder 2, the connecting plate 4 will slide on the inner wall of the limit plate 3. As the connecting plate 4 moves, the limit block 7 will slide inside the guide groove 8. The limit block 7 will squeeze the stopper 12 during the sliding process. The stopper 12 slides toward the inside of the mobile bin 9 under the force. At this time, the connecting column 10 and the spring 11 will be compressed under the force, which can make the limit block 7 move more smoothly along the guide groove 8. As the limit block 7 moves, the height of the connecting column 6 can be adjusted, and then the tension of the protective film can be adjusted.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
