Description

technical field [0001] The invention relates to a protective film production line, in particular to a protective film winding device for conveniently disassembling and installing a reel. Background technique [0002] According to the application, the protective film can be divided into digital product protective film, car protective film, household protective film, food fresh-keeping protective film and so on. With the popularization of digital products such as mobile phones in China, protective film has gradually become a general term for screen protective film, and its functions in the field of screen protective film are also varied, the earliest high-definition scratch-resistant, and now Hong Kong GLAUKE, 180 degrees And the favor of OK8 functional protective film. The material has experienced more than 5 years of development from the earliest PP material to the current popular AR material, and has gradually been accepted by the majority of mobile phone groups.
