A traction device of a zipper punching machine comprises a left support, a right support, a support seat rested on the upper sides of the left support and the right support, a first tension spring and a second tension spring. A zipper tape pulling wheel is mounted between the left support and right support. A first zipper tape pressing wheel and a second zipper tape pressing wheel are respectively embedded into the opposite lateral walls of the left support and the right support in an up-down slidable manner. The upper end of the first tension spring is connected with the first zipper tape pressing wheel, and the lower end of the first tension spring is connected with the left support. The upper end of the second tension spring is connected with the second zipper tape pressing wheel, and the lower end of the second tension spring is connected with the right support. By the first tension spring and the second tension spring, the worn first zipper tape pressing wheel and second zipper tape pressing wheel can attach to the zipper tape pulling wheel so as to allow the stress of the two zipper tapes of a zipper to be balanced, perfect positioning during the zipper punching process can be achieved, zipper punching quality can be increased, and zipper quality can be increased.
Description
technical field [0001] The invention relates to a structure on a chain flushing machine, in particular to a traction device for a chain flushing machine. Background technique [0002] At present, when the zipper is processed, the teeth are first implanted on the cloth belt to form a chain belt of tens or even hundreds of meters, and then the fixed-size chain is punched and removed through the chain flushing machine, so that there are no teeth on the chain belt at equal intervals. The chain belt knife edge is used to produce the chain belt of the required length, and the chain element segment of the finished zipper is between the two chain belt knife edges. [0003] At present, the traction force of the chain flushing machine is provided by the upper and lower pressure wheels of the traction device. Due to the flexibility of the zipper itself, metal wheels are generally used for the lower pulley set, and plastic wheels are used for the upper pressure wheel. After a period of ...
