[0003] In the prior art, a packing bag production sewing device is disclosed in a patent with the authorization publication number CN 220099353 U. When the packing bag needs to be sewn, the electric push rod starts to operate by controlling the switch group, and the extension end of the electric push rod drives the sliding block and the packing bag clamping plate to move, so as to adjust the distance between the two packing bag clamping plates and the distance between the two belts. According to the thickness of the packing bag that needs to be sewn, the distance between the two belts is adjusted, the sewing machine and the motor start to operate by controlling the switch group, the output shaft of the motor drives the belt pulley and the belt to start to operate, and the packing bag that needs to be sewn is placed between the two belts. Under the driving action of the two rotating belts, the packing bag can be transported. It is found in the use process that when the packing bag is placed, the position of the packing bag sewing may be placed too high or too low, resulting in uneven quality of the packing bag production. In addition, when the packing bag is placed, there is no supporting structure near the port, which may cause the bag opening to deviate to one side, resulting in the occurrence of adverse conditions in the sewing operation.
