An imitation slider type chain closure device of a nylon zipper sewing machine

Abstract

An imitation slider type chain closure device of a nylon zipper sewing machine, including a base, a lower base plate, a support core, an upper left cover and an upper right cover, the lower base plate is detachably installed on the top surface of the base, and the top surface of the lower base plate There is a limit hole on the top, and the support core is provided with a lower step correspondingly installed in the limit hole in the middle and lower part. Between the bottom surface of the cover and the top surface of the lower bottom plate, between the bottom surface of the upper right cover and the top surface of the lower bottom plate, there is respectively a gap for the cloth belt of the single side zipper white embryo to pass through, and between the upper left cover, the upper right cover and the support core. Form a Y-shaped chain-closing passage for the elements of the unilateral zipper on both sides to be chained together. The slider-like chain closure device of the present invention can completely replace the combination function of the ordinary slider through the detachable assembly of the limit, etc., and the assembly accuracy is high, and the support core does not produce deviation and the white blank of the unilateral zipper on both sides. The chain teeth produce friction to ensure the smooth operation of the chain closure.

Description

technical field [0001] The invention relates to the field of zipper manufacturing equipment, and more specifically refers to a slider-like chain closure device of a nylon zipper sewing machine. Background technique [0002] Nylon zipper sewing machine uses suture (or upper thread) and bottom thread to sew the elements of the zipper, zipper tape and other components together to form a semi-finished nylon zipper --- nylon zipper blank. However, after the traditional nylon zipper sewing machine sews the zipper car, the unilateral nylon zipper white embryo is output, and the two unilateral nylon zipper white embryos cannot be closed. [0003] In order to solve the above problems, the Chinese utility model whose authorization notification number is CN 203904654U discloses a chain closing device for a zipper sewing machine. It is sewn together with the cloth tape into two parallel zipper sides, and the zipper side is drawn and closed by a zipper device fixed on the sewing table t...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a slider-like closure device for a nylon zipper sewing machine to solve the problem that the existing closure device used for a zipper sewing machine fixes the slider on the bracket as a closure, which is easy to wear and needs to be replaced frequently. Otherwise, defects such as poor thread mesh, burst teeth or defective products are prone to occur during the production process.
