Description

Technical Field

[0001] This utility model relates to the technical field of CPP film production equipment, specifically to a static elimination device for CPP film. Background Technology

[0002] In the production process of CPP (cast polypropylene) film, static electricity is easily generated by friction between the film and the surfaces of equipment such as guide rollers, as well as friction between films themselves. Static electricity accumulation may cause the film to attract dust and other impurities, affecting the appearance quality of the film; it may also cause the films to adhere to each other, creating wrinkles during the winding process, affecting the flatness of the product; and electrostatic discharge may cause safety hazards such as fire or explosion, especially in environments with flammable and explosive gases or dust.

[0003] The existing static eliminators for CPP film still have the following problems when in use: their static eliminator coverage is limited, and the effective range of their static eliminator mechanism is relatively narrow. They can usually only eliminate static electricity in the nearby film area. For wider CPP film production lines, they may not be able to completely cover the entire width of the film, resulting in incomplete static electricity elimination at the film edges.
