Packaging bag production equipment

The utility model relates to packaging bag production equipment, which belongs to the technical field of production and comprises two support frames, a transmission roller for transmission is rotatably arranged between the two support frames, and first hydraulic rods are fixedly arranged on the outer walls of the support frames. The scrap edge cutting device has the advantages that the two-way lead screw sliding table is arranged in the fixing frame, the blades arranged at the two telescopic ends of the two-way lead screw sliding table can rotate through the first motor and meanwhile cooperate with the first hydraulic rod to move downwards to cut off scrap edges, and the distance between the two blades can be adjusted through driving of the moving end of the two-way lead screw sliding table; in the adjusting process, the pointer on the outer wall of the movable end moves along with the adjusting device, the distance can be effectively judged by matching with the scale marks on the outer wall of the fixing fra
