When the coating device is used, silicone oil is added into the trough, the plastic film is sent into a position between the first coating roller and the second coating roller from one side provided with the scraper, the mechanism capable of moving up and down lifts the first coating roller to compress the plastic film, the power mechanism rotates the second coating roller, meanwhile, the silicone oil in the trough is sent into the spraying pipe by the hydraulic pump to spray the second coating roller, the silicone oil on the second coating roller is more uniformly distributed through the scraper in the rotating process of the second coating roller, then the silicone oil is transferred to the upper side of the plastic film, and the silicone oil in the trough is transferred to the lower side of the plastic film by the first coating roller.
Preferably, the mechanism capable of moving up and down comprises an air cylinder and a sliding block, a rectangular through hole is formed in the supporting plate, the sliding block capable of sliding up and down is arranged in the rectangular through hole, the air cylinder is vertically arranged on the supporting plate, the extending end of the air cylinder is fixedly connected with the sliding block, the first coating roll is rotatably connected with the sliding block, and the sliding block is driven to move up and down through the up-and-down movement of the air cylinder, so that the first coating roll is driven to move up and down.
Further, the length of the scraper is larger than that of the second coating roller, and when the silicone oil sprayed onto the second coating roller by the spray pipe is excessive, the excessive silicone oil is scraped by the scraper and flows into the trough from two sides of the scraper.
The utility model has the beneficial effects that: the lower side of the plastic film can be coated by the first coating roller, and the upper side of the plastic film can be coated by the second coating roller, so that lubricating oil can be uniformly coated on both sides of the plastic film.
