Double closed zipper automatic head threading machine

Abstract

The invention discloses an automatic zipper head penetrating machine for a two-way end closing zipper. The automatic zipper head penetrating machine comprises a machine frame, a zipper belt conveying device arranged on the machine frame, a cutter support device, a zipper head conveying device, a zipper head clamping device and a zipper closing device for closing the zipper belt which is separated after the zipper penetrates through the zipper belt, wherein the zipper closing device comprises a zipper closing anvil die which is fixedly arranged on the machine frame, a zipper closing lower die which is arranged on the machine frame in a movable mode and is driven by a third power device; the zipper closing groove is formed on the zipper closing lower die; the zipper closing lower die is a zipper head which is split; and when the zipper belt passes through the zipper closing groove, the zipper head penetrates through the zipper belt in the forward direction, so that the zipper belt is closed. By the automatic zipper head penetrating machine, automatic zipper penetrating and end and zipper closing are realized on one machine, so that the two-way end closing zipper can be produced continuously and automatically, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a device for manufacturing zippers, in particular to an automatic head-threading machine for double-closed zippers. Background technique [0002] The zipper includes (two) zipper tapes, a slider, and an upper stop and a lower stop fixed at the ends of the zipper tapes, and chain teeth are arranged on the zipper tapes. In order to facilitate automatic production, the zipper tape is made into dozens of meters or even hundreds of meters. According to the length required by the user, a part of the chain teeth is removed at intervals to form a knife edge. During production, it is convenient for the knife to extend into the knife edge to open the opening. [0003] There are many types of zippers, such as double bottom stop zippers and top stop bottom stop zippers. The zipper slider was originally done manually, but the zipper needs to be cut first, and the zipper is cut, and the unskilled new workers can’t get it in, so the manual s...

AI Technical Summary

Problems solved by technology

The zipper slider was originally done manually, but the zipper needs to be cut first, and the zipper is cut, and the unskilled new workers can’t get it in, so the manual slider is inefficient. High labor intensity and high cost

[0004] In recent years, there have been some zipper threading machines on the market for automatic threading of top-stop and bottom-stop zippers. Due to the limitation of the slider structure, the known automatic threading equipment for zippers can only be reverse threading (zipper reverse Head-through means that the zipper tape enters from the closing end of the slider and exits from the split end of the slider), so after the slider is inserted, the zipper tape that the slider passes through will be opened, and no double ends can be produced. closed zipper

For the double bottom stop zipper, which is widely used in the market, it needs to close the chain after the automatic head threading, but the automation equipment has not been able to solve this problem, which has become a bottleneck in the development of zipper automation.
