Detection device for dimensions of yarns, cotton threads and centre lines of zippers

Abstract

A detection device for dimensions of yarns, cotton threads and centre lines of zippers comprises pressing devices on two sides, the pressing device on one side comprises a pressing shaft, the pressing shaft and a pressing spring A are pressed in a pressing support seat, the pressing device on the other side is mounted on a fixed support seat through a drive shaft and comprises a locking shaft, the locking shaft and a pressing spring B are mounted in a locking support, and a pressing rod is fixedly connected with the locking support. The other end of the drive shaft extends out of the fixed support seat to be connected with a connecting shaft, a drawstring spring is mounted on the connecting shaft, the other end of the connecting shaft is connected with a nut, and a lubricating nipple is mounted at the upper end of the fixed support seat. A limiting support A and a limiting support B are mounted at two ends in the front of a fixed bottom plate, a measurement slide shaft and a slide limiting plate are mounted between the limiting support A and the limiting support B, and measurement devices including a slide shaft sleeve, a linear bearing, a dial indicator seat and a micrometer are mounted on the measurement slide shaft. The detection device is capable of measuring the thicknesses of various pure or blended yarns and cotton threads, simple in structure, convenient to adjust and detach and capable of guaranteeing product quality stability by comparison measurement.

Description

technical field [0001] The invention relates to the technical field of detection equipment for zippers, in particular to a detection device for the center line size of zipper yarns, cotton threads and zipper tapes. Background technique [0002] Zipper is a connecting piece that relies on continuous arrangement of chain teeth to make items merge or separate. It is widely used in clothing, bags, tents, etc. The zipper is mainly composed of cloth tape, chain teeth, handle, slider, limit code or locking parts. Among them, the flat pull strength of the zipper package and the self-locking force of the zipper affect the quality of the finished zipper, and generally need to be tested. The thickness of the center line of the cloth tape has a great influence on the flat pull strength of the code and the self-locking force of the zipper, so the detection of the thickness of the center line of the cloth tape is also particularly important. In the prior art, the detection of the center...

AI Technical Summary

Problems solved by technology

In the prior art, the detection of the center line of the cloth tape generally adopts the weighing method. The heavier the zipper of the same type, the better its corresponding strength and other performances are generally. The weighing method cannot be controlled, and the weighing method is a special method for zipper quality identification, which cannot guarantee the stability of product quality. For the detection and identification of product quality, it is necessary to cooperate with other objective and scientific tests.
