A yarn detection device and detection method

Abstract

The present invention proposes a yarn detection device and a detection method, wherein the yarn detection device includes a support base, the support base has a lower support rod and an upper support rod, and the upper support rod is provided with a plurality of longitudinal chute; A plurality of lower fixing clips are fixedly installed on the lower support rod; a plurality of longitudinal sliders, each of which is movably limited in one of the longitudinal chute; a plurality of upper fixing clips, each The upper fixing brackets are respectively fixedly installed on a longitudinal slider; the movable cutting knife assembly is arranged on the side of the support base away from the lower fixing clip; a plurality of telescopic rods are fixedly installed on the support base and are movable. The ends are respectively fixedly connected with a longitudinal slider; multiple pressure sensors; and a control system. The fast and convenient installation of the yarn can be realized by winding the yarn, and then the yarn on the other side is cut off, so as to complete the installation process of multiple yarn segments to be tested, and then the tensile test is carried out by applying a thrust. Quick and easy.

Description

technical field [0001] The invention relates to the technical field of yarn detection, in particular to a yarn detection device and a detection method. Background technique [0002] The tensile strength of yarn is an important index to evaluate the performance of yarn. [0003] In the prior art, the tensile strength test process of the yarn is mainly as follows: fix the two ends of the yarn to be tested on the two ends of the stretching device respectively, and then gradually apply the tensile force until the yarn is broken, and collect Stretch information. [0004] But the inventor finds that in the experimental process in the prior art, there are at least the following problems: [0005] In actual production, a type of yarn generally requires at least a dozen tensile tests, but the current tensile test equipment can only install one yarn to be tested at a time. After installing and testing the yarn, It is necessary to remove the broken thread after detection, and then i...

Problems solved by technology

[0005] In actual production, a type of yarn generally requires at least a dozen tensile tests, but the current tensile test equipment can only install one yarn to be tested at a time. After installing and testing the yarn, It is necessary to remove the broken yarn after detection first, and then install a new yarn to be detected for the next detection, resulting in low detection efficiency
