[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0027] Reference Figures 1-4 A film roll device for producing PVC vacuum film includes an operating table 1, a U-shaped frame 2 is fixed at one end of the top of the operating table 1, a guide wheel 13 is fixed at one end inside the U-shaped frame 2, and the PVC vacuum film is guided by the guide wheel 13. A cleaning mechanism is provided inside the U-shaped frame 2, and the cleaning mechanism includes a nozzle 12. Support frames 11 are fixed at the top and bottom ends of the U-shaped frame 2, and the nozzle 12 is fixed at one end of the two support frames 11 close to each other. A water tank 3 and a water pump 4 are fixed at the top of each U-shaped frame 2, the input end of the water pump 4 is fixed to the water tank 3 through a conduit, and the output end of the water pump 4 is fixed to the nozzle 12 through a conduit;

[0028] The PVC vacuum film is guided and transported to the inside of the U-shaped frame 2 by the guide wheel 13, so that the PVC vacuum film can be rolled up. At this time, the output end of the water pump 4 uses the clean water in the water tank 3 to clean the PVC vacuum film, preventing dust and pollutants from damaging the PVC vacuum film and making it difficult to clean.

[0029] The cleaning mechanism includes a water collecting component, and the other end of the U-shaped frame 2 is provided with a water collecting component; the water sprayed for cleaning is absorbed by the water collecting component;

[0030] The water collecting assembly includes a B adsorption roller 10. The other end of the U-shaped frame 2 is connected to the B adsorption roller 10. The other ends of both sides of the U-shaped frame 2 are provided with sliding grooves. The interior of the sliding grooves is slidably connected to the A adsorption roller 9. Slide blocks 5 are fixed on both sides of the A adsorption roller 9. The bottom end of the slider 5 is fixed to a first spring 14. The bottom end of the first spring 14 is fixed to a fixing plate 7. The ends of the two fixing plates 7 that are close to each other are fixed to the U-shaped frame 2.

[0031] The position of the B suction roller 10 is fixed, and it slides through the A suction roller 9 and the sliding groove. The elasticity of the first spring 14 drives the A suction roller 9 to squeeze the direction of the B suction roller 10, so that the distance between the A suction roller 9 and the B suction roller 10 can be adjusted automatically according to the thickness of the different PVC vacuum films, which is convenient for improving the adhesion of the A suction roller 9 and the B suction roller 10 to the PVC vacuum film and improving the moisture adsorption of the PVC vacuum film.

[0032] A winding mechanism is provided at the other end of the top of the operating table 1. The winding mechanism includes two adjustment plates 16. The adjustment plates 16 are fixed on both sides of the other end of the top of the operating table 1. The ends of the two adjustment plates 16 that are close to each other are connected to clamping blocks 15. The ends of the two clamping blocks 15 that are close to each other are fixed with anti-slip particles. A servo motor is fixed to one side of one of the adjustment plates 16, and the output end of the servo motor is fixed to one of the clamping blocks 15.

[0033] The servo motor drives the clamping block 15 and the winding roller to rotate, thereby winding the PVC vacuum film, and the anti-slip particles are used to increase the friction between the clamping block 15 and the winding roller to prevent the clamping block 15 and the winding roller from idling;

[0034] The winding mechanism includes an adjustment component, and the bottom end of the adjustment plate 16 is provided with an adjustment component, and the adjustment component includes a forward and reverse threaded rod 19. The other end inside the operating table 1 is connected to the forward and reverse threaded rod 19. Both sides of the outer side of the forward and reverse threaded rod 19 are threadedly connected to the adjustment plate 16. A hand wheel 17 is fixed to one side of the forward and reverse threaded rod 19.

[0035] Turning the hand wheel 17 drives the forward and reverse threaded rods 19 to rotate synchronously, so that the two adjustment plates 16 slide towards or away from each other, and then can be adjusted according to different winding rollers and the width of the PVC vacuum film;

[0036] An L-shaped frame 8 is fixed to the other end of one side of the operating table 1. One end of the interior of the L-shaped frame 8 is slidably connected to a clamping rod 6. A second spring 18 is sleeved on the outer side of the clamping rod 6. One end of the second spring 18 is fixed to the L-shaped frame 8, and the other end of the second spring 18 is fixed to the clamping rod 6. One end of the clamping rod 6 is slidably connected to a hand wheel 17.

[0037] When the width of the winding roller is adjusted to be appropriate, the elasticity of the second spring 18 drives the clamping rod 6 and the hand wheel 17 to limit the position, preventing the forward and reverse threaded rods 19 from reversing, and avoiding the clamping block 15 from fitting loosely with the winding roller, resulting in the servo motor being unable to drive the winding roller to rotate and rewind.

[0038] The utility model provides a method of using a film rolling device for producing PVC vacuum film as follows: when in use, the PVC vacuum film is placed from the surface of the guide wheel 13 so that the PVC vacuum film passes between the B suction roller 10 and the A suction roller 9 for winding. At this time, the clamping rod 6 is pulled to drive the second spring 18 to elastically extend, and the clamping rod 6 is disengaged from the hand-turned wheel 17. The hand-turned wheel 17 is turned to drive the forward and reverse threaded rods 19 to rotate synchronously, so that the two adjustment plates 16 slide toward one end closer to or farther away from each other, and then the width of the film can be adjusted according to different winding rollers and PVC vacuum film. When the width suitable for the winding roller is adjusted, the clamping rod 6 and the hand-turned wheel 17 are limited by the elasticity of the second spring 18, so as to prevent the forward and reverse threaded rods 19 from reversing, thereby preventing the clamping block 15 from being loosely attached to the winding roller, resulting in the servo motor being unable to drive the winding roller to rotate and wind;

[0039] The PVC vacuum film is transported along the guide of the guide wheel 13. At this time, the output end of the water pump 4 sprays the clean water inside the water tank 3 along the conduit from the nozzle 12 to the PVC vacuum film, thereby simply cleaning the upper and lower surfaces of the PVC vacuum film. Finally, the PVC vacuum film is adsorbed with moisture by the A adsorption roller 9 and the B adsorption roller 10, thereby cleaning the dust on the surface of the PVC vacuum film and improving the protective effect of the PVC vacuum film.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification.
