Method for processing nylon zipper and zipper stopper and zipper stopper welder

Abstract

The present invention discloses a nylon zipper. It includes the following several portions: two zipper strips, two tooth chains which are respectively fixed on the opposite edges of the described two zipper strips, lower stop fastener fixed in the lower end portion of the described two tooth chains and upper stop fastener fixed in the upper end portion of the described two tooth chains. The described upper stop fastener and lower stop fastener are made up by using plastic sheet respectively, the described plastic sheets are respectively welded on the projected surfaces of said two tooth chains. Besides, said invention also provides a zipper stop fastener welding machine and a processing method of said zipper stop fastener.

Description

technical field [0001] The invention relates to the technical field of zippers, in particular to a nylon zipper; the invention also relates to a processing method for a zipper stopper and a molding device for a zipper stopper. Background technique [0002] Most of the known zipper stoppers are metal buckles. Because the metal buckle is bent from a metal strip, its two ends are not closed, so the two ends are easy to scratch the clothing close to it. If the zipper is installed on The two ends of the pillow, which do not close the metal buckle, are also prone to trapping human hair. Not only that, when the slider hits the upper stop or the lower stop repeatedly, because the two ends of the metal buckle are not closed, the metal buckle is easily opened, causing the slider to slip off from the tooth chain. [0003] There is also a buckle made of nylon material, which is injection-molded between the upper and lower surfaces of two zipper tapes and connects the ends of the two zi...

AI Technical Summary

Problems solved by technology

[0002] Most of the known zipper stoppers are metal buckles. Because the metal buckle is bent from a metal strip, its two ends are not closed, so the two ends are easy to scratch the clothing close to it. If the zipper is installed on Pillows, the two ends of the metal buckle not closed, also prone to trapping human hair

Not only that, when the slider repeatedly hits the upper stop or the lower stop, because the two ends of the metal buckle are not closed, it is easy to make the metal buckle open, causing the slider to slip off from the tooth chain

[0003] There is also a buckle made of nylon material, which is injection-molded between the upper and lower surfaces of two zipper tapes and connects the ends of the two zipper tapes together. Its cross section is "I"-shaped. Although it solves the problem that the metal buckle is easy to scratch the clothing, because the nylon material is hard after heat curing, and the buckle is fixed between the upper and lower surfaces of the zipper tape, the zipper will not be damaged when the zipper is sewn on the clothing. It is easy to lay flat, and the buckle is also easily broken by the head of the sewing machine

[0004] At the same time, most of the zipper buckles are injection molded, that is, the molten plastic is directly injected into the upper or lower end of the zipper tape to form a closed or "I"-shaped buckle, which has low efficiency and unstable quality.
