Description

Technical Field

[0001] The utility model relates to a gluing device, in particular to a gluing device for a PET protective film. Background Art

[0002] PET protective film is a kind of film material widely used in various fields. It is mainly made of polyester. This material has good transparency, heat resistance, chemical stability and mechanical strength, making it an ideal protective film.

[0003] The adhesive layer on the PET protective film is the key to ensuring that the protective film plays its protective role. The correct adhesive can improve the overall performance of the product and meet the needs of different application fields. In the experimental gluing process of the existing PET protective film, glue needs to be applied on the protective film and then flattened with a scraper. The existing gluing device pours glue on the protective film and then flattens it with a scraper. However, due to the different widths of the protective film, different adjustments need to be made after the glue is poured to ensure that the glue is evenly spread and applied. For this reason, we propose a gluing device for PET protective film. Utility Model Content
