Description

technical field [0001] The invention relates to a zipper positioning device, in particular to a zipper positioning device applied to a zipper cutting machine. Background technique [0002] In the zipper production process of the prior art, due to the various types of pull tabs assembled on the zipper slider, when the existing zipper cutting machine cuts the zipper, the positioning device often cannot identify the zipper pull well. head, it is easy to cause the misoperation of the zipper cutting machine, cut off and injure the pull tab, and cause the zipper to be scrapped; especially for some pull tabs with ropes and some pull tabs with holes, it is easy to cause the positioning device to malfunction. The crochet needle produces wrong induction, and eventually the zipper cutting machine cuts off or injures the zipper when cutting the zipper, so that the zipper is scrapped, and more waste zippers are produced, which reduces the production pass rate and cannot effectively save ...

[0002] In the zipper production process of the prior art, due to the various types of pull tabs assembled on the zipper slider, when the existing zipper cutting machine cuts the zipper, the positioning device often cannot identify the zipper pull well. head, it is easy to cause the misoperation of the zipper cutting machine, cut off and injure the pull tab, and cause the zipper to be scrapped; especially for some pull tabs with ropes and some pull tabs with holes, it is easy to cause the positioning device to malfunction. The crochet hook produces wrong induction, which eventually causes the zipper cutting machine to cut off or injure the zipper when cutting the zipper, so that the zipper is scrapped, and more waste zippers are produced, which reduces the production pass rate and cannot effectively save production costs.
