[0002] Protective films can be divided into digital product protective films, car protective films, household protective films, food preservation protective films, etc. according to their uses. During the production process of protective films, they need to be rewound by a rewinder. A rewinder is a special equipment for paper, mica tape, and film. Its purpose is to rewind paper, film, etc. in sequence, and make them into finished products after rewinding.

[0003] When in use, the traditional rewinding machine directly puts the film roller on the winding roller and only limits the winding roller. There is no corresponding limiting mechanism after the film rollers of different lengths are placed on the winding roller, so the film roller is not sufficiently constrained and limited, which makes it easy for it to slip and cause rewinding failure. In addition, the traditional rewinding machine requires manual cutting with a knife at the end of film winding, which is not only easy to cut crookedly, but also easy to cause injuries due to operational errors.

[0004] Therefore, a protective film rewinding machine is proposed to solve the above problems. Utility Model Content
