Self-balancing device for unwinding paper passing roller of aluminum-foil paper splitting machine

The invention discloses a self-balancing device for an unwinding paper passing roller of an aluminum-foil paper splitting machine, which relates to the technical field of aluminum-foil paper processing equipment and comprises a rack, a guide frame, a segmented unwinding mechanism and a self-balancing mechanism. According to the device, the slit aluminum-foil paper can be intermittently and sectionally unwound, so that air possibly remaining in narrow paper can be extruded in subsequent winding, accumulated staggered layers are avoided, and the feeding flatness of the aluminum-foil paper is guaranteed; under the condition that any position of the synchronously unwound aluminum-foil paper tape is broken in the unwinding stage, the swing arm drives the overturning roller to overturn towards one side of the winding roller under the action of the elastic force of the spring until the overturning roller is attached to a part of the wound aluminum-foil paper roll in the corresponding winding roller, and the winding
