[0013] Compared with the prior art, the advantages of the utility model are:

[0014] 1. The woven bag in production is transported by the operating conveyor belt so that the end of the woven bag fits with the side wall of the limiting plate. Then the conveyor belt stops transporting the woven bag and limits the woven bag. The hydraulic cylinder pushes the plate to move downward. During the process of the plate driving the cutting knife to move downward, the lower end of the movable plate first fits with the surface of the woven bag, and the plate drives the cutting knife to continue to move downward, so that the movable plate and the plate slide through and at the same time, the movable plate is pulled by the tension of the spring, so that the lower end of the movable plate presses and limits the woven bag, and then the woven bag is cut by the cutting knife, thereby limiting the woven bag in production and making the cutting knife cut the woven bag at a fixed point, so as to avoid the woven bag from being offset when the cutting knife cuts the woven bag, resulting in defects in the woven bag after cutting, affecting the quality of the woven bag.

[0015] 2. After the woven bag is cut, the limit plate is driven by the driving motor to rotate so that the side wall of the limit plate is separated from the end of the woven bag. Then the conveyor belt operates to transport the cut woven bags to the collection frame, so as to facilitate the centralized collection of the woven bags. Then the driving motor drives the electric limit plate to rotate so that the limit plate is placed horizontally between the two vertical plates, and then the rear woven bag is limited, so that the length of the woven bag remains consistent after cutting.
