[0002] Transfer film is a printing process that is widely used in the printing industry, especially in the furniture manufacturing industry. Transfer film is used for surface decoration. It can transfer the wood grain decorative pattern printed on it to the board coated with glue, and it can be easily maintained and not easy to fall off, so it is widely used; metal transfer film needs to use a winding device in the production process. It is difficult to fix films of different widths. As a result, CPP films of different widths are prone to deviation during winding, which has certain limitations in use. Therefore, the metal transfer film needs to be positioned during the winding process.

[0003] The patent with application number 202322096772.7 discloses a film winding device, which relates to the field of film processing, including a mounting plate, a vertical plate and a motor.
