Yarn detector assembly

Abstract

The invention belongs to the technical field of textile equipment, and discloses a yarn detector assembly. The yarn detector assembly comprises a yarn detector, a first iron sheet, a second iron sheetand a third iron sheet. The first iron sheet comprises a sector segment and a first vertical segment. A first yarn passing hole is formed in the end of the sector segment and provided with an annularrubber ring. First strip-shaped holes are formed in the two sides of the first vertical segment. The second iron sheet comprises a second vertical segment and a transverse segment. A second yarn passing hole is formed in the end of the third iron sheet and provided with an annular rubber ring. Third strip-shaped holes are formed in the two sides of the third iron sheet. According to the yarn detector assembly, the annular rubber rings are arranged on the first yarn passing hole and the second yarn passing hole, when yarn shakes too violently to impact on the annular rubber rings, the annularrubber rings can achieve a certain buffer function, the yarn can restore to the original position faster, and therefore the stability of infrared pulses received by the yarn detector is kept, and detection precision is increased.

Description

technical field [0001] The invention belongs to the technical field of textile equipment, and in particular relates to a thread detector assembly. Background technique [0002] The doubling machine is used as the pre-processing equipment of the two-for-one twisting machine. Its main function is to combine two or more strands of yarn into one yarn, so as to facilitate the processing of the two-for-one twisting machine. In the yarn merging process, it is inevitable to encounter yarn breakage or the end of winding. In order to avoid problems such as single yarn or missing strands during production, a yarn breakage automatic stop device must be used. At present, there are mainly two kinds of mainstream yarn-breaking self-stop devices, one is mechanical type, and the other is photoelectric type self-stop device. [0003] The mechanical self-stop device mainly controls the movement of the winding part through the mechanical principle to control the winding of the yarn. The struc...

AI Technical Summary

Problems solved by technology

[0004] The photoelectric self-stop device currently used has good self-stop effect when the yarn breaks, but there are defects such as independent installation of auxiliary parts, poor integration, inconvenient installation and adjustment, and inconvenient maintenance after parts are damaged.

At the same time, because each component is installed separately, the yarn path is longer and the yarn tension is high, which may easily cause fluffing and breakage of the yarn, affecting production and yarn quality
