[0020] During operation, the photoelectric sensor 71 is used to monitor in real time the change in the distance between the two sides of the film and the photoelectric sensor 71 during the movement. When the distance changes, the controller 72 controls the lifting assembly 6 to drive the lower pressure roller 5 to descend and cooperate with the fixed roller 4 to press the film. Then the driving mechanism 3 is used to drive the mounting frame 2 to drive the film to slowly move horizontally to adjust the center line of the film.
