Miniature yarn tension measuring sensor

Abstract

The invention relates to a miniature yarn tension measuring sensor. The miniature yarn tension measuring sensor comprises a shell, a support base, a porcelain tube, an elastic element, insulating damping adhesive, sealing tape, screws, a gasket, nuts and a transmitter circuit board. In the conveying process, yarn passes through the porcelain tube of the miniature yarn tension measuring sensor in a pressing mode at a certain angle, under the action of yarn tension, the porcelain tube is pressed downwards to cause deformation of the elastic element, a strain bridge converts induced deformation into electric signals in proportion and transmits the electric signals to the transmitter circuit board, and the transmitter circuit board amplifies and outputs the electric signals to a yarn conveyor control module. According to the current yarn tension, the control module controls an executive component of a conveyor to execute operation according to preset programs, and stability of yarn conveying is ensured. The miniature yarn tension measuring sensor is simple in structure, small in size, high in accuracy, long in service life, capable of measuring the yarn tension in real time when applied to the yarn conveyor, and beneficial for enhancing control over yarn conveying and improving yarn conveying efficiency and quality.

Description

technical field [0001] The invention relates to a tension measuring sensor, in particular to a miniature sensor for automatically measuring the tension of moving yarns on-line. technical background [0002] In the yarn feeding and storage device of the textile machine, the tension of the yarn is often unstable during the conveying process, resulting in yarn breakage due to excessive yarn tension or the phenomenon that the yarn cannot be conveyed due to insufficient tension, which affects the weaving efficiency of the yarn. and weave quality. Contents of the invention [0003] The purpose of the present invention is to provide the yarn feeder with an online real-time tension signal of the yarn, so as to provide a control method for the yarn feed, prevent the yarn from being broken or the yarn is too soft to be fed, and improve the yarn weaving efficiency. [0004] In order to achieve the above object, the technical solution of the present invention is: a kind of miniature ...
