Abstract

The invention relates to the technical field of laser cutting, and discloses a sweeper sheet metal part laser cutting system based on a rapid material returning structure, which comprises a material returning part, the material returning part is positioned above a material guide port, the material returning part comprises a protective frame fixedly connected with the top end of a roller conveyor belt, a movable part is arranged at the top end of the inner wall of the protective frame, and the movable part comprises an electric guide rail. A material returning pressing roller is arranged on the inner wall of the electric guide rail, the material returning pressing roller rotates while reciprocating on the inner wall of the electric guide rail, the material returning pressing roller comprises a rotating roller, and a stretching structure is arranged on the inner wall of the rotating roller. The material returning press roll is arranged, rotation and reciprocating sliding of the material returning press roll are combined, a press piece can apply pressure to an effective part from different angles and positions, the composite motion can more comprehensively act on the connecting portion of the part and a mother piece, the connecting force is effectively overcome, and especially for parts with complex shapes and irregular connecting point distribution, the material returning press roll can be used for pressing the part. The separation success rate can be obviously improved.
