A cleaning component 2 is installed on the inner wall of the housing 1 for cleaning the plastic film, and a water removal component 3 is installed on the inner wall of the housing 1 for absorbing water stains on the surface of the plastic film. The device also includes:

[0021] The cleaning component 2 includes a threaded post 201, which is rotatably mounted on both sides of the inner wall of the housing 1. A first connecting block 202 is threadedly connected to the side wall of the threaded post 201. A sleeve plate 203 is fixedly connected to the side wall of the first connecting block 202. A cleaning block 204 is slidably connected to the inner wall of the sleeve plate 203. A spring 205 is fixedly connected between the cleaning block 204 and the sleeve plate 203.

[0022] Both the sleeve plate 203 and the cleaning block 204 have curved sides, and the sleeve plate 203 and the cleaning block 204 on both sides of the box 1 are set in opposite directions;

[0023] It should be noted that: the plastic film passes through the bottom of the rotating roller 102, and the rotating threaded column 201, through the threaded connection between the threaded column 201 and the first connecting block 202, causes the first connecting block 202 to drive the sleeve 203 to slide on the side wall of the threaded column 201, thereby causing the cleaning blocks 204 on both sides of the box 1 to stick to the upper and lower surfaces of the film respectively. When the film is transported, the cleaning blocks 204 can use clean water to clean the upper and lower surfaces of the film. The spring 205 can keep the cleaning blocks 204 in contact with the film and adapt to the jumping of the film during the transport process.

[0024] Reference Figures 1-4 The dewatering component 3 includes a connecting box 301, which is fixedly installed on the top of the side wall of the housing 1. A bidirectional threaded rod 302 is rotatably connected to the side wall of the connecting box 301.

[0025] The two-way threaded rod 302 has a second connecting block threadedly connected to both side walls, and a connecting bracket 303 is fixedly connected to the side wall of the second connecting block.

[0026] A water-absorbing roller 304 is rotatably connected to the inner wall of the connecting frame 303, and a scraper 305 is fixedly connected to the inner wall of the connecting frame 303. The scraper 305 and the side wall of the water-absorbing roller 304 are in contact, and a water outlet is opened at the bottom of the connecting frame 303.

[0027] It should be noted that: the film is passed through the middle of the connecting frame 303, the bidirectional threaded rod 302 is rotated, and the threaded connection between the bidirectional threaded rod 302 and the second connecting block is used to make the second connecting block drive the connecting frame 303 to slide towards the middle, and then the absorbent roller 304 is used to clamp the film in the middle. When the film is transported, the absorbent roller 304 will rotate to absorb the moisture on the surface of the film, and then the scraper 305 is used to remove the water stains on the surface of the absorbent roller 304. The removed water stains can flow out of the connecting frame 303 through the outlet.

[0028] Reference Figures 1-4 A mounting plate 4 is fixedly connected to the top of the housing 1, a servo motor 401 is fixedly connected to the side wall of the mounting plate 4, and a rotating shaft 402 is fixedly connected to the output end of the servo motor 401.

[0029] A limit ring is fixedly connected to the side wall of the rotating shaft 402, a take-up roller 403 is slidably connected to the side wall of the rotating shaft 402, and a fixing ring 404 is threadedly connected to the side wall of the rotating shaft 402.

[0030] Both the bidirectional threaded rod 302 and the threaded column 201 have nuts 405 threadedly connected to their side walls. The nuts 405 are used to fix the bidirectional threaded rod 302 and the threaded column 201.

[0031] It should be noted that: the film passes through the bottom of the rotating roller 102, the cleaning component 2 is placed on both sides of the film surface, the film passes through the middle of the connecting frame 303, and then the film is wound around the side wall of the take-up roller 403. The take-up roller 403 is fixed to the side wall of the rotating shaft 402 by the limiting ring and the fixing ring 404. The rotating shaft 402 is driven to rotate by the servo motor 401, and the rotating shaft 402 drives the take-up roller 403 to rotate to wind up the film, so that the film is transferred on the cleaning component 2 and the dewatering component 3, which facilitates cleaning and dewatering.

[0032] Operating procedure: Pass the film through the bottom of the rotating roller 102, place the cleaning component 2 on both sides of the film surface, then pass the film through the middle of the connecting frame 303, and then wrap the film around the side wall of the take-up roller 403. The take-up roller 403 is fixed to the side wall of the rotating shaft 402 by the limiting ring and the fixing ring 404. Rotate the threaded column 201, and use the threaded connection between the threaded column 201 and the first connecting block 202 to make the first connecting block 202 drive the sleeve 203 to slide on the side wall of the threaded column 201, thereby making the cleaning blocks 204 on both sides of the box 1 fit against the upper and lower surfaces of the film respectively. Rotate the bidirectional threaded rod 302, and use the threaded connection between the bidirectional threaded rod 302 and the second connecting block to make the second connecting block drive the connecting frame 303 to slide towards the middle, thereby using the absorbent roller 304 to clamp the film in the middle.

[0033] The servo motor 401 drives the rotating shaft 402 to rotate, which in turn drives the take-up roller 403 to rotate and take up the film. At this time, the film is transported on the cleaning component 2 and the dewatering component 3. The cleaning block 204 can clean the upper and lower surfaces of the film with clean water. The spring 205 can keep the cleaning block 204 in contact with the film and adapt to the jumping of the film during transport. At the same time, the water absorption roller 304 rotates to absorb the moisture on the surface of the film, and the scraper 305 removes the water stains on the surface of the water absorption roller 304. The removed water stains can flow out of the connecting frame 303 through the water outlet. In summary, the film can be cleaned and then dewatered, and finally it can be directly wound up, which is convenient for operation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
