Plastic film surface coating technology

Abstract

The invention relates to a plastic film surface coating technology. The plastic film surface coating technology comprises the following steps that S1, a plastic film roller is mounted, the plastic film cut into 0.8-1.5 meters is arranged on a material placing device; S2, corona treatment is conducted, a BY-3000 corona processor is adopted to carry out continuous corona on the to be coated surfaceof the plastic film; S3, levelling pretreatment is conducted, after corona, the leveling treatment of the plastic film is conducted with a leveling device; S4, coating treatment is conducted, the surface of the plastic film is subjected to coating with a coating device; S5, drying treatment is conducted, the surface of the plastic film is dried with hot-air drying equipment; and S6, rolling is conducted, the plastic film is rolled by a rolling mechanism. The plastic film surface coating technology can solve the problems of wrinkling, plastic film position deviation, low coating uniformity anddifficult cutting blade cleaning in an existing plastic film coating process. The function of automatic plastic film coating is achieved.

Description

technical field [0001] The invention relates to the technical field of plastic film processing, in particular to a plastic film surface coating process. Background technique [0002] In recent years, the application of plastic film products in various fields has become more and more popular. In order to meet the actual needs of different fields, during the production and processing process, a layer of coating with special functions is often coated on the surface of the plastic film. The quality of the film can be improved and the application range can be expanded by implementing a functional coating on the surface of the plastic film. However, when coating the surface of the plastic film, it is difficult to fix the position of the plastic film. Therefore, during the coating process, the position of the plastic film is prone to shift, resulting in wrinkles, which increases the difficulty of normal coating. In addition, during the coating process, a scraper is often used to l...
