[0031] Furthermore, the side wall of the nip roller 7 is provided with a circle of positioning grooves 71 aligned with the annular cutting groove 41. By adopting the positioning grooves 71, the staff can be assisted to quickly identify and confirm the cutting position of the device, so as to improve the cutting efficiency of the device.

[0032] The working principle of this embodiment:

[0033] When it is necessary to cut the thread ends of the woven bag, first open the rotating assembly 8, drive the pressing roller 7, the feeding roller 4 and the cutting roller 5 to rotate, then place the woven bag flat on the feeding plate 6, and align the cut thread ends of the woven bag with the positioning groove 71 on the side wall of the pressing roller 7, and then manually insert one end of the woven bag into the gap between the pressing roller 7 and the feeding plate 6, so that the pressing roller 7 feeds the woven bag into the hook of the J-shaped frame 3. At this time, the feeding roller 4 and the pressing roller 7 in the hook of the J-shaped frame 3 rotate in opposite directions and at the same speed, and the feeding roller 4 is coaxial with the arc surface of the hook of the J-shaped frame 3, so it is fed into the hook of the J-shaped frame 3 by the pressing roller 7 and the feeding plate 6. The woven bag will pass along the gap between the outer contour of the feeding roller 4 and the arc surface of the hook of the J-shaped frame 3. At the same time, because the annular cutter 51 on the cutting roller 5 passes through the arc hole 31 and extends into the annular groove 41 on the feeding roller 4, and the positioning groove 71 of the pressing roller 7 is aligned with the annular groove 41, the thread ends of the woven bag will be cut by the annular cutter 51 and the annular groove 41 rotating in opposite directions when passing through the above-mentioned gap, and slide into the square groove body 9 of the J-shaped frame 3. Finally, the woven bag with the thread ends cut off will slide out along the plane of the J-shaped frame 3 under the feeding plate 6, thereby realizing automatic and rapid cutting of the thread ends of the woven bag.
