[0031] In this embodiment, in order to achieve the positioning and conveying effect of the cut woven bags, a positioning and conveying component 4 is designed. Two telescopic cylinders 4-1 are arranged on the surface of the equipment frame 1. The output end of the telescopic cylinder 4-1 is connected to a telescopic adjustment rod 4-2, and the telescopic adjustment rod 4-2 can be telescopic. A fixed frame 4-3 is connected to the output end of the telescopic adjustment rod 4-2. Two second cylinders 4-4 are installed on the fixed frame 4-3.

After the position is corrected, the fourth cylinder 6-1 is started to push the correction frame 6-2 to fit one side of the woven bag. The edge of the woven bag is located above the rotating roller 4-8 and between the clamping wheel 4-7. Then the cutting is started, and the third cylinder 5-2 is started to push the sleeve frame 5-3 downward, so that the lower pressure frame 5-5 cooperates with the spring 5-4 to press the woven bag downward, so that the woven bag contacts the cutting frame 5-7 through the cutting groove, and the heating resistor 5-8 is started to keep the cutting frame 5-7 in a heated state. After cutting, the rotating roller 4-8 is started to transport the woven bag to the surface of the conveyor belt, and it is pressed tightly with the leveling roller 4-10. Then the slitting machine body 3 is started, and the conveyor belt 4-9 is started at the same time. The slitting process of the woven bag is completed during the transportation process, and the next woven bag can be cut during the slitting process.
