A winding roller 6 is provided at the other end of the substrate 1. A servo motor is connected to the end of the winding roller 6. A fixing seat 4 is provided in the middle of the substrate 1. A lower pressure roller 401 and an upper pressure roller 402 for lamination are provided on the fixing seat 4.

[0034] The lower pressure roller 401 is rotatably mounted in the middle of the fixed base 4, and a cylinder 403 is fixed to the top of the fixed base 4. The shaft of the cylinder 403 is vertically downward and is fixed to a movable frame 404. The upper pressure roller 402 is rotatably mounted on the lower end of the movable frame 404. In specific implementation, the lower pressure roller 401 and the upper pressure roller 402 are horizontally parallel to each other.

[0035] like Figure 2As shown, a guide frame 3 is provided between the unwinding frame 2 and the fixed base 4. Two guide plates 301 (a total of 8) are provided on the guide frame 3 for each unwinding roller 201. The guide plate 301 has a mounting groove 303 in the middle. A guide roller 304 is rotatably installed in the mounting groove 303. The upper and lower edges of the guide roller 304 are exposed above the upper and lower end faces of the guide plate 301, respectively, and can be used to directly contact the film.
