Description

Technical Field

[0001] The present application belongs to the field of PET film processing technology, and in particular relates to a PET film cleaning device. Background Art

[0002] PET release film, also known as thermal transfer film, peeling film, isolation film, slip film, thinner paper, silicone oil film, anti-stick film, silicone oil release paper, silicone oil paper, masking film, PET release film is also called PET transfer film, which is mainly used as a carrier for vacuum aluminum plating. That is, the PET film is placed in a vacuum aluminum plating machine for aluminum plating, and then coated with glue and compounded with paper. Then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the cardboard through the adhesive action to form the so-called aluminum-plated cardboard. When the PET release film is produced, the surface is easily contaminated with some dirt, dust, paper hair, paper scraps, etc., which can easily cause impurities in the coating. Therefore, the surface of the material needs to be dusted during the production process.

[0003] For example, the existing document: Chinese patent application number 202322251343.2 discloses a PET release film surface cleaning device, comprising a base, a working box fixedly connected to the top of the base, a first support block fixedly connected to the side of the working box, a first water tank fixedly connected to the top of the working box, two L-shaped support blocks fixedly connected to the bottom of the interior of the working box, grooves slidably connected to the tops of the two L-shaped support blocks, handles fixedly connected to the sides of the grooves, a conveying mechanism fixedly connected to the tops of the first support blocks, a support plate fixedly connected to the inner wall of the working box, and a cleaning mechanism fixedly connected to the interior of the working box. Although the above scheme utilizes the mutual cooperation of the conveying mechanism and the cleaning mechanism to clean dust from both sides of the PET release film, it is easy to cause scratches on the film surface when using a cleaning brush to clean the film surface, which directly affects the processing quality of the film and reduces the quality of the film.
