Slide fastener belt conveying device

Abstract

The invention discloses a slide fastener belt conveying device, comprising a resistance detection unit, an over-large resistance protection unit and a synchronization adjustment unit, wherein the resistance detection unit is used for detecting the width of a slide fastener belt so as to avoid the problem of excessive thickness and excessive size of an interface caused by bad connection of the slide fastener belt, and the unqualified slide fastener belt is to be locked in the resistance detection unit and cannot pass through. The over-large resistance protection unit cooperates with the resistance detection unit, when the slide fastener belt locked by over-large resistance, the over-large resistance protection unit starts to stop the machine so as to protect the slide fastener belt. The synchronization adjustment unit is used for keeping constant tension of the slide fastener belt in the operation process of the slide fastener belt so as to maintain the conveying of the slide fastener belt and the balance necessary for the conveying. For the problems of gradual change and sudden change of the slide fastener belt, the slide fastener belt conveying device can keep the conveying tension of the slide fastener belt constant, and can maintain the balance between the needed quantity of the slide fastener belt and the needed conveying quantity, thereby improving quality of products, immediately stopping machine to protect the unqualified slide fastener belt and completely eradicating the damage on the machine caused by the unqualified slide fastener belt.

Description

technical field [0001] The invention relates to the field of automatic zipper tooth chain manufacturing machinery, in particular to a zipper tape conveying device for controlling and adjusting the conveyance of the zipper tape when continuously feeding the zipper tape into the zipper manufacturing machine. Background technique [0002] The zipper chain continuous manufacturing machine in the prior art specifically includes: the forming implant part of the meshing element, the metal wire feeding device that intermittently feeds the metal wire rod of the meshing original to the forming implant part, and sends out the zipper string The fastener tape is intermittently supplied to the fastener tape supply device and the like of the molding implantation part. Such as patent literature Japanese Patent Publication No. 59-51813 communique. [0003] However, when the engaging elements are continuously added to the zipper tape, it is required that the zipper tape must be continuously ...

AI Technical Summary

Problems solved by technology

[0004] Since the length of the zipper tape is very long, and the zipper tape is also continuously supplied for a long time, when the quality, thickness or other physical properties of the zipper tape gradually change, it will gradually accumulate and change during the long-term conveying process, resulting in obvious changes. The feed rate changes, and if the change in the feed rate reaches a certain level, it will eventually lead to abnormal production. For example, once the feed rate gradually increases to a certain level, it will cause the zipper tape to relax and cannot be produced. The amount of feed gradually decreases, which will eventually cause the zipper tape to be too tight, which will make the pitch of the engaging elements attached to the zipper tape uneven, affecting the quality of the zipper

[0005] Furthermore, in order to keep the zipper machine able to produce for a long time, the zipper belt raw material cloth belt will be spliced ​​to obtain a sufficient length, and once there is a bad connection, such as the splice suddenly becomes larger, If it becomes thicker, it will cause damage to the accessories when it is fed into the row of teeth, which will cause serious production accidents such as downtime and affect the degree of mechanical automation.
