Servo bag holding, edging folding and bag sewing mechanism in full-automatic packing machine

The utility model relates to a servo bag holding, edging folding and bag sewing mechanism in a full-automatic packing machine. According to powder products produced in current industries such as chemical engineering and fertilizer, due to the fact that generated gas is difficult to discharge, bags fall easily, gas is discharged through long-time still standing or vibration by using rotating tables, multiple working stations and other structure, and thus the defects of being low in working efficiency and complex in structure exist. The servo bag holding, edging folding and bag sewing mechanism in the full-automatic packing machine is structurally composed of a servo motor reducer (1), an edge folding machine (12), a bag sewing machine (13) and a bag holding device, wherein the servo motor reducer (1), the edge folding machine (12), the bag sewing machine (13) and the bag holding device are arranged on a rack. The output side of the servo speed reducer (1) is connected with a synchronous belt wheel (2), a synch
