The invention relates to a slitter edge automatic winding and collecting device. The slitter edge automatic winding and collecting device comprises a device frame supporting mechanism, a slitter edge longitudinal moving mechanism, an oscillating rod mechanism, a slitter edge winding mechanism and an electrical detecting control system. An upper longitudinal moving retainer wheel (209) is installed at the upper end of the slitter edge longitudinal moving mechanism. A longitudinal moving retainer wheel (210) is arranged below the upper longitudinal moving retainer wheel (209) of the slitter edge longitudinal moving mechanism. The longitudinal moving retainer wheel (210) is connected to the slitter edge longitudinal moving mechanism in an up-down moving mode. The oscillating rod mechanism is connected to the frame supporting mechanism in a left-right oscillating mode. The oscillating rod mechanism is provided with an upper oscillating retainer wheel (406) and a lower oscillating retainer wheel (407). The slitter edge winding mechanism is sleeved with a waste film winding drum used for winding slitter edges (500) of a packaging film. The slitter edge automatic winding and collecting device is of a vertical structure, and the slitter edges of the thin film is evenly wound on the waste film winding drum of the thin film under the guidance of a longitudinal moving support ring and the four retainer wheels, so that automatic collecting of the slitter edges of the thin film is achieved; job sites are cleaned, and the occupied area is small.
