Description

Mounting device for back-to-back double-zipper head

Technical Field

The invention relates to the technical field of garment processing, in particular to a mounting device for back-to-back double zipper sliders.

Background

The zipper is a connecting piece for combining or separating articles by means of continuously arranged zipper teeth, and is widely used on daily articles such as clothes, bags, tents and the like.

The existing slide fastener includes various types such as a single open-end slide fastener and a double open-end slide fastener. The single-pull closed-end zipper is the most common zipper and is widely applied to places such as coverlets, pockets of clothes, trouser stops and the like; the single-open-end zipper is a zipper with an upper stop and a lower stop, a pull head is generally arranged on the single-open-end zipper, when the single-open-end zipper is pulled, the pull head moves from one end of the lower stop to one end of the upper stop, so that the two parallel cloth belts with zipper teeth can be folded, and when the single-open-end zipper is separated, the pull head is pulled reversely to separate the two parallel cloth belts.

And the other zipper, namely the zipper with two ends capable of being opened and closed through the movement of the sliders, is provided with at least two sliders (for the convenience of distinguishing, the two sliders are respectively called as a forward slider and a reverse slider in the application), when the two sliders move along the same direction, one slider is used for realizing the splicing of the two cloth belts on the zipper, and the other slider is used for realizing the separation of the two cloth belts, namely the two sliders are used for realizing the opposite directions of the splicing and the separation of the cloth belts. The double-puller closed-tail zipper is more applied to the opening of the luggage leather, can open the luggage opening at multiple positions randomly in multiple directions, and is more convenient and flexible to use. And a double slider zipper.

The zipper head penetrating machine is equipment for clamping a zipper head into zipper teeth at a head penetrating station, and a zipper can be closed or separated along with the movement of the zipper head. The existing zipper puller assembling device can only assemble one zipper puller into a zipper at each time, when the zipper puller of the double-puller closed-end zipper is used for threading, one zipper puller needs to be firstly threaded, the direction of the zipper is changed, and then the other zipper puller is threaded, so that the whole assembling process is long in time consumption and low in production efficiency.

As shown in fig. 1, in the process of assembling the double-end zipper, it is relatively easy to insert the zipper teeth into the large end of the slider, but it is very difficult to insert the zipper teeth into the tail of the slider, and manual installation cannot be completed, so that a double-zipper mounting device needs to be designed to reduce the installation difficulty and improve the production efficiency.
