[0003] Currently, after the production and shaping of plastic sheets, they are usually wound up by a winding method. However, the wound plastic sheets are likely to adhere to each other, which is not conducive to the subsequent release of the plastic sheets. Moreover, during the release process, the plastic sheets are prone to being pulled and deformed, or even torn and damaged. For this reason, we propose an anti-sticking device for plastic sheets. Content of the Utility Model
[0004] The purpose of the utility model is to provide an anti-sticking device for plastic sheets, which has the advantages of evenly applying anti-sticking oil to the surface of plastic sheets before winding, so as to avoid the sticking phenomenon of the wound plastic sheets, thus facilitating the subsequent release of the plastic sheets, and also avoiding the pulling deformation or tearing damage of the plastic sheets due to adhesion during the release process. It solves the problem that currently, after the production and shaping of plastic sheets, they are usually wound up by a winding method, and the wound plastic sheets are likely to adhere to each other, which is not conducive to the subsequent release of the plastic sheets, and during the release process, the plastic sheets are prone to being pulled and deformed, or even torn and damaged.

Specific embodiments
[0020] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] As Figures 1-4 shown, a non-sticking device for plastic sheets proposed by the present utility model includes a conveyor frame 4. Mounting blocks 10 are welded to both sides of the front and rear surfaces of the conveyor frame 4 near the lower surface. Mounting holes are provided on the upper surfaces of the four mounting blocks 10. After the bolts pass through the mounting holes, the conveyor frame 4 can be installed at the use position. Conveyor rollers 3 are symmetrically installed near the upper and lower surfaces inside the conveyor frame 4. The plastic sheet passes between the two conveyor rollers 3. Then, the two rotating conveyor rollers 3 drive the plastic sheet to move and be conveyed. A conveyor motor 2 is fixedly installed on one side of the outer surface of the conveyor frame 4. The end of the output shaft of the conveyor motor 2 is connected to one end of the conveyor roller 3 close to the conveyor motor 2. Both ends of the two conveyor rollers 3 away from the conveyor motor 2 are connected with transmission gears 6, and the two transmission gears 6 are meshed with each other. The conveyor motor 2 drives one of the conveyor rollers 3 to rotate, and the two conveyor rollers 3 are driven by the meshed transmission gears 6.
[0022] A gear cover 5 is installed on one side of the outer surface of the conveyor frame 4 near the transmission gear 6, and both of the two transmission gears 6 are located inside the gear cover 5. The gear cover 5 plays a role in protecting the transmission gear 6. A first frame 1 and a second frame 11 are respectively installed on the front and rear surfaces of the conveyor frame 4. The first frame 1, the conveyor frame 4, and the second frame 11 are all in a square shape in side view and are through on both sides. First electric push rods 8 are installed on the upper and lower surfaces of the first frame 1, and the output ends of the two first electric push rods 8 are both connected with first scrapers 9. The two first electric push rods 8 drive the two first scrapers 9 to lift and lower, so that the two first scrapers 9 contact the upper and lower surfaces of the plastic sheet, and scrape off the dust, impurities, and residual water on the upper and lower surfaces of the plastic sheet. On both sides of the opposite sides of the two first scrapers 9, first slide bars 7 are connected, and the first slide bars 7 penetrate through the first frame 1. The first slide bars 7 can improve the stability of the first scrapers 9.
[0023] The upper and lower surfaces of the second frame 11 are both installed with second electric push rods 16, and the output ends of the two second electric push rods 16 are both connected with second scraping plates 15. Both the first scraping plate 9 and the second scraping plate 15 are made of flexible materials with a hardness lower than that of the plastic sheet, so as to avoid scratching the surface of the plastic sheet. The two second electric push rods 16 drive the two second scraping plates 15 to lift and lower, so that the two second scraping plates 15 approach the upper and lower surfaces of the plastic sheet and scrape off the excess anti-sticking oil. At both sides of the opposite sides of the two second scraping plates 15, second sliding rods 17 are connected, and the second sliding rods 17 penetrate through the second frame 11. The second sliding rods 17 can improve the stability of the second scraping plates 15. Sponge plates 14 are installed on the front surfaces of the two second scraping plates 15. Branch pipes 12 are connected to the opposite sides of the two sponge plates 14, and the ends of the branch pipes 12 are connected with oil pipes 13. The anti-sticking oil is transported into the sponge plates 14 through the oil pipes 13 and the branch pipes 12 and infiltrates the sponge plates 14, and then the anti-sticking oil is transferred to the surface of the plastic sheet through the sponge plates 14.
[0024] When the present utility model is in use, before the plastic sheet is wound up, it first passes through the first frame 1, and then the two first scraping plates 9 scrape off the dust, impurities and residual water on the upper and lower surfaces of the plastic sheet. The two conveying rollers 3 play a role in conveying the plastic sheet. The cleaned plastic sheet passes through the second frame 11, and then the two sponge plates 14 infiltrated with anti-sticking oil apply the anti-sticking oil to the upper and lower surfaces of the plastic sheet. Then when the plastic sheet passes through the two second scraping plates 15, the two second scraping plates 15 scrape off the excess anti-sticking oil on the upper and lower surfaces of the plastic sheet. Then after the plastic sheet is wound up, due to the existence of the anti-sticking oil, the plastic sheet will not stick, which is convenient for the subsequent release of the plastic sheet, and also avoids the plastic sheet from being pulled and deformed or torn and damaged due to adhesion during the release process.
[0025] The above specific embodiments are only several preferred embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
