Abstract

This utility model discloses a rotating device for changing the unwinding direction of a film, relating to the field of film production technology. It includes a rotating assembly that supports the film roll and can adjust its horizontal position to change the unwinding direction towards the feed end. The rotating assembly includes a support base rotatably disposed beside the feed end, with the axis of rotation of the support base arranged vertically. A roll support platform for supporting the film roll is provided on the support base. This utility model conveniently changes the unwinding direction of the film roll through the rotating assembly, avoiding the dangers and complexities of conventional overhead lifting and adjustment methods.
