DETAILED DESCRIPTION

[0073] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0074] like Figure 1-2 As shown, this embodiment proposes a plastic film cleaning device, comprising a first machine plate 1, a feeding roller 3, a winding roller 17, a second machine plate 2 and a film conveying assembly, wherein the feeding roller 3 is mounted on the first machine plate 1, the winding roller 17 is mounted on the second machine plate 2, and the film conveying assembly is mounted on the first machine plate 1 and the second machine plate 2;

[0075] It also includes a first cleaning mechanism 7 and a second cleaning mechanism 9, wherein the first cleaning mechanism 7 is mounted on the first machine tool plate 1, and the second cleaning mechanism 9 is mounted on the second machine tool plate 2, and is used to clean the two surfaces of the plastic film respectively, and the film conveying assembly conveys the plastic film so that the two surfaces of the plastic film pass through the first cleaning mechanism 7 and the second cleaning mechanism 9 respectively;

[0076] The first cleaning mechanism 7 and the second cleaning mechanism 9 have the same structure. The first cleaning mechanism 7 includes a plurality of rotatable cleaning pads. When cleaning the plastic film, the cleaning pads can be replaced by rotating.

[0077] The film conveying assembly comprises:

[0078] A second mounting frame 4, wherein the second mounting frame 4 is mounted on the first machine tool plate 1;

[0079] A first transmission roller group 5, wherein two rollers of the first transmission roller group 5 are arranged in a horizontal direction, and the first transmission roller group 5 is mounted on the second mounting frame 4;

[0080] A second transmission roller group 6, wherein two rollers of the second transmission roller group 6 are arranged in a vertical direction, the second transmission roller group 6 is mounted on the second mounting frame 4, the second transmission roller group 6 is located above the first transmission roller group 5, and the first cleaning mechanism 7 is located between the unwinding roller 3 and the first transmission roller group 5;

[0081] A third transmission roller group 8, wherein the third transmission roller group 8 is installed on the second machine tool plate 2;

[0082] The fourth transmission roller group 10 is installed on the second machine tool plate 2 , and the second cleaning mechanism 9 is located between the third transmission roller group 8 and the fourth transmission roller group 10 .

[0083] In this embodiment, when the plastic film cleaning device is used, the finished plastic film roll is first mounted on the unwinding roller 3, then unwinds from the unwinding roller 3, passes through the two rollers of the first transmission roller group 5 from bottom to top, then passes between the two rollers of the second transmission roller group 6 from the side away from the first cleaning mechanism 7, then passes through the third transmission roller group 8 and the fourth transmission roller group 10 in sequence, and finally is collected on the winding roller 17 to complete the cleaning;

[0084] The plastic film passes through the first cleaning mechanism 7 at the position between the discharge roller 3 and the first transmission roller group 5. The first cleaning mechanism 7 cleans the first side of the plastic film, then bypasses the second transmission roller group 6, and when passing the position between the third transmission roller group 8 and the fourth transmission roller group 10, the second cleaning mechanism 9 also cleans the other side of the plastic film, thereby realizing double-sided cleaning of the plastic film and achieving an excellent cleaning effect. During the cleaning process, only one of the several rotating cleaning pads contacts the plastic film at a time to clean and absorb dust and impurities on the surface of the plastic film. After a period of use, the next cleaning pad is rotated and adjusted to contact the plastic film, thereby avoiding long-term contact cleaning between a single cleaning pad and the plastic film and avoiding a decrease in the cleaning effect. At the same time, the cleaning pad that has been used last can be cleaned to facilitate the next use, thereby realizing automatic replacement and cyclic cleaning of the cleaning pad, ensuring an excellent cleaning effect on the plastic film.

[0088] A rotating central axis 20, wherein the rotating central axis 20 is rotatably mounted on the fifth mounting frame 19;

[0089] The cleaning pad is a sponge pad 22 , and a plurality of sponge pads 22 are provided. The plurality of sponge pads 22 are distributed in an annular shape and are equidistantly installed on the outer ring surface of the rotating central shaft 20 .

[0091] In this embodiment, when the plastic film passes through the sponge pad 22, the top sponge pad 22 is in a flat state and fully contacts the surface of the plastic film. Then the plastic film and the sponge pad 22 move by friction, and the impurities on the plastic film are cleaned and adsorbed by the sponge pad 22 to achieve cleaning. After a period of use, the rotating shaft 20 rotates, and the next sponge pad 22 is driven to move upward through the branch plate 21 to contact the surface of the plastic film. The last used sponge pad 22 moves downward to the cleaning chamber 18. The cleaning liquid or cleaning water in the cleaning chamber 18 will clean the used sponge pad 22. This cycle can ensure that the sponge pad 22 used in the cleaning process is in a relatively clean state, so that it can ensure the best cleaning effect and avoid the impurities on the sponge pad 22 from adhering to the plastic film for the second time.

[0100] In this embodiment, after the two sides of the plastic film are cleaned by the first cleaning mechanism 7 and the second cleaning mechanism 9, the plastic film will pass through the two wiping plates 13. At this time, the two sets of first lifting driving members 12 respectively drive the two wiping plates 13 to approach each other, so that the two wiping plates 13 are respectively close to the two surfaces of the plastic film, wiping and absorbing the small amount of water remaining on the surface, thereby reducing the residual water.

[0128] In this embodiment, when a sponge pad 22 that has finished cleaning moves into the cleaning chamber 18, the branch plate 21 is facing vertically downward, and the sponge pad 22 is in a horizontal state and immersed in the cleaning chamber 18, and then the two self-cleaning components move close to each other, and then the electric slide 26 drives the moving frame 27 to move on the moving slide rail 25 close to the sponge pad 22 and move to the working position, and then the four telescopic driving members 29 on the two self-cleaning components extend to drive the four electromagnetic ball seats 30 to move to the position of the four control balls 24, and the electromagnetic ball seats 30 are energized to attract and fix the control balls 24, and then the four telescopic driving members 29 contract, and then the four pull ropes 23 are pulled to tighten them, and the four corners of the sponge pad 22 are gathered to the middle branch plate 21, and finally the sponge pad 22 is folded from the midline position, and the two sides of the sponge pad 22 are folded upward to the two sides of the branch plate 21, that is, at this time, both sides of the sponge pad 22 are folded upward and tightened;

[0129] The second lifting drive member 31 then extends downward, and the two second lifting drive members 31 drive the cleaning brushes 33 to move downward through the connecting plates 32, and the cleaning brushes 33 will contact one side of the upwardly folded sponge pad 22, and scrub from top to bottom. After the cleaning brush 33 moves a certain distance, the cleaning brush 33 will pull the second shaft rod 36 downward through the first shaft rod 34 and the first linkage rod 35, and the two second shaft rods 36 drive the scraper 38 to start moving downward, and the other ends of the two second shaft rods 36 move downward in the inclined slide rails 37 through the sliders, that is, the scraper 38 will move downward in contact with the surface of the sponge pad 22, and at the same time, due to the inclined state of the inclined slide rails 37, the scraper 38 will gradually approach the sponge pad 22 and gradually press it, and then scrape downward, the cleaning brush 33 will brush out the impurities in the holes of the sponge pad 22, and then the scraper 38 will scrape off the brushed impurities together, completing the impurity separation, and at the same time, the scraper 38 forms a strong compression and scraping on the sponge pad 22, achieving an excellent scraping effect;
