As the diameter of the film roll wound by the core drum on the winding station becomes larger and larger, under the guidance of the guide block on the swing seat and the arc guide groove, the film roll gradually pushes the winding roller on the swing seat to move backward, gradually stretching the auxiliary friction roller and the winding roller that are in contact with each other, until the film is completely wound on the core drum, so that the core drum with the wound film automatically falls onto the storage tank. The above-mentioned elastic pressing mechanism can use a spring assembly or a passive cylinder.
