Description

technical field [0001] The invention relates to a protective film production device, in particular to a protective film cutting device. Background technique [0002] After the processing of electronic equipment such as laptops is completed, a protective film will be attached to the casing. The protective film is usually made of polyester film, which has the characteristics of high transparency, scratch resistance, dustproof, and waterproof, and can effectively protect electronic equipment from damage. For protective film manufacturers, after the processing of the protective film is completed, the protective film needs to be wound up according to a certain length, and then transported to the notebook computer manufacturer. However, after the protective film is wound, the excess part needs to be cut The traditional way is to use manual cutting, which is not only inefficient, but also artificial cutting is irregular, which is easy to cause waste of protective film. At the same ...
