Guide rail head penetrating machine and head penetrating method thereof

Abstract

The invention belongs to the technical field of zipper equipment, and particularly relates to a guide rail head penetrating machine and a head penetrating method thereof. The guide rail head penetrating machine comprises a guide rail head die holder, wherein a positioning groove used for containing a guide rail head is formed in the guide rail head die holder; a minute hand capable of moving up and down relative to the positioning groove is arranged on one side of the guide rail head die holder; a first power piece capable of controlling the minute hand to move is connected to the minute hand;a crochet hook used for hooking a guide rail head pull piece is arranged in the guide rail head die holder; a linkage block is formed at the lower end of the crochet hook; a linkage groove is formedin the linkage block; a second power piece for controlling the linkage block to move is arranged on one side of the guide rail head die holder; a connecting base aligned with the linkage groove is arranged on the second power piece; a linkage rod embedded into the linkage groove and inserted into the connecting base is connected between the linkage block and the second power piece; the linkage rodcan ascend and descend relative to the linkage block and the connecting base; and the acting force of the second power piece on the crochet hook can be changed by ascending and descending the linkagerod. The head penetrating machine can enable a chain belt to stably penetrate through the guide rail head.

Description

technical field [0001] The invention belongs to the technical field of zipper equipment, and relates to a guide rail head threading machine and a threading method thereof. Background technique [0002] Zipper is a common connecting piece on various clothing, bags, tents and other items. According to the different items for which the zipper is applicable, the types of sliders on the zipper are often different. Among them, the guide rail head is a slider with a relatively special structure, which can be used on both sides. It is often used in some products that can be used on both sides, such as clothing that can be worn on both sides. [0003] For example, CN201821813806.2 discloses a guide rail head, including a zipper body, an upper cover is fixed on the upper part of the zipper body, the zipper body and the upper cover form a zipper inner core, and a clearance fit is provided outside the zipper inner core Removable cap, a horse hook respectively forms a locking structure ...

AI Technical Summary

Problems solved by technology

However, when the pull tab of the rail head is hooked by a crochet hook, there will be friction between the pull tab of the rail head and the cap. The force will also be large, so that the cap is not easy to be pushed, that is, it will cause certain obstacles to the equipment to release the safety of the guide rail head, causing the chain belt to fail to pass through the guide rail head smoothly.
