When the C-shaped plate moves, it drives the pressing roller to approach the winding roller. When the pressing roller contacts the film wound on the winding roller, as the winding roller rotates, the wound film causes the pressing roller to move. When the pressing roller moves, it drives the moving shaft to slide on the fixed rod. When the moving shaft moves, it causes Spring 1 to contract. By applying a uniform pressure to the wound film through the pressing mechanism, it prevents uneven phenomena such as wrinkles and ripples from occurring during the winding process of the film.
