Synchronous belt modules have advantages such as fast movement speed, high reciprocating positioning accuracy, and fatigue resistance, and are widely used in automated production equipment for different commodity materials. The automatic threading and cutting zipper machine, also known as the threading and pulling machine, automatically feeds materials through a vibrating disc, and the synchronous belt module quickly pulls out the fabric zipper/nylon zipper. When it is pulled to the set length, the threading machine automatically cuts the zipper. This reciprocating operation achieves fast and automatic production of the zipper.

From the diagram, you can see the structure of the automatic zipper cutting machine. The synchronous belt module is equivalent to a robotic arm on this automated equipment. The puller is hung on the slider of the module and follows the slider to quickly move, pulling the zipper out of the output port of the vibrator. The automation requirements of the automatic zipper cutting machine are not high. As long as the speed is fast and the positioning needs to meet a certain degree of accuracy, it can ensure that the length of the zipper fabric produced is consistent. Choosing a synchronous belt module is the most appropriate. Moreover, synchronous belt modules are a relatively affordable type among similar transmission mechanisms, and choosing synchronous belt modules can reduce the cost of the entire machine. The structure of the synchronous belt module is also relatively simple, which can save maintenance trouble and costs during the later use of the equipment.
