The detection piece 32 is suitable for detecting the length of the rubber needle belt 6 output from the second discharge port 21, and the cutter 31 is suitable for cutting the rubber needle belt 6.

[0031] In this example, the cutting mechanism 3 comprises a cutter 31 and a detection piece 32, and the detection piece 32 can detect the length of the rubber needle belt 6 output from the second discharge port 21. When the length of the output rubber needle belt 6 reaches a preset value, the cutter 31 can automatically cut the rubber needle belt 6, thereby realizing automatic cutting and improving the degree of automation of the stretching machine, thereby facilitating the production efficiency of the rubber needle belt 6.

[0032] It should be noted that, as Figures 1 to 3 shown, the rubber needle belt 6 is formed by a plurality of rubber needle pins connected in sequence. The production raw material can include polypropylene (PP), nylon (PA) or polyester (PET) and the like. The rubber needle belt 6 is used in cooperation with a rubber nail machine to connect a hang tag or the like to a product.
