Specifically, the movement of a string of cut pieces connected by the fishing line 22 along the feeding platform 121 can be achieved by the cooperation of the feeding platform 121 and the feeding assembly 122; detecting whether the fishing line 22 of the cloth piece 21 is located within the detection interval in the vertical direction by the cooperation of the first detecting element 1331 and the second detecting element 1332 of the thread cutting device 130; when the first detecting element 1331 detects the cloth 21 and the second detecting element 1332 does not detect the cloth 21, it means that the fishing line 22 is located within the detecting interval in the vertical direction, and the fishing line 22 on the cloth 21 is cut by the line cutter 134; when neither the first detecting element 1331 nor the second detecting element 1332 detects the cloth piece 21, the thread cutting platform 132 is driven to move towards the feeding platform 121 by the thread cutting driving part 135 until the first detecting element 1331 detects the cloth piece 21 and the second detecting element 1332 does not detect the cloth piece 21; when the first detecting element 1331 and the second detecting element 1332 detect the cloth pieces 21, the thread cutting platform 132 is driven by the thread cutting driving component 135 to move away from the feeding platform 121 until the first detecting element 1331 detects the cloth pieces 21 and the second detecting element 1332 does not detect the cloth pieces 21, the thread cutting mechanism 100 can automatically identify whether the positions of the fishing threads 22 between the cloth pieces 21 are at the thread cutting positions of the thread cutters 134, and when the fishing threads 22 are not at the thread cutting positions, the positions of the thread cutters 134 can be automatically adjusted, so that the degree of automation is high, the time and the force are saved, and the thread cutting efficiency is high. The cut-off piece strings 20 with the cut-off lines enter a folding interval between a first folding roller 220 and a second folding roller 230 of the folding device, two surfaces of the cut-off piece strings 20 are simultaneously matched with the first folding roller 220 and the second folding roller 230 in a contact mode, the first folding roller 220 and/or the second folding roller 230 are driven to rotate through a folding driving part, the first folding roller 220 and the second folding roller 230 are rotated in opposite directions to output the cut-off piece strings 20, the folding support 210 is driven to swing back and forth in the horizontal plane through a swinging driving part, the output cut-off piece strings 20 are folded in an S shape, and are folded neatly without manual repeated arrangement and collection.
