Rove siro spinning broken-strand detection and indication device

Abstract

The invention discloses a rove siro spinning broken-strand detection and indication device. The device comprises a set of siro spinning broken-strand detection and indication unit mounted in each spindle place of a ring spinning frame for producing siro spun yarns correspondingly. A set of infrared transmission tube and receiving tube and infrared intensity intelligent analysis unit are arranged on each set of the siro spinning broken-strand detection and indication unit, and the infrared transmission tube and receiving tube and the infrared intensity intelligent analysis unit are arranged in a specially designed casing, and the casings are fixed on the outside of a spinning cone of the ring spinning frame. Whether rove broken strands occur is determined and indicated through current or voltage change characteristics caused by the infrared receiving tubes. The basis for determination is that single-yarn passing time averages are divided into three conditions of close to 0, half of a set value and close to the set value, and the three conditions are corresponding to two rove broken strands, one rove broken strand and non rove broken strand. The device is simple in structure and applicable to detection of siro spinning broken-strand detection of various ring spinning modes of cotton spinning, wool spinning, colored spinning and the like.

Description

technical field [0001] The invention belongs to the technical field of textiles, and further relates to textile electromechanical products, devices, processes and methods, in particular to a detection and indication device for siro spinning roving sliver breaks. Background technique [0002] The siro spinning process is a new spinning process jointly researched by Australia's CSIRO laboratory and the International Wool Bureau (IWS). Its initial design purpose is to fully utilize the advantages of less hairiness, high strength and good wear resistance , to achieve the effect of single-yarn weaving without sizing, and the effect of light and thin wool fabric. In recent years, due to the improvement of hairiness, siro spinning has been widely used in the spinning of pure cotton and recycled fibers. [0003] The principle of siro spinning figure 1 shown. Two rovings kept at a certain distance are fed in parallel to the same drafting mechanism of the ring spinning frame throug...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned first method is to directly monitor whether the roving itself is broken, the number of sensors required is large, and the space is limited during installation; the second method can only detect the situation that all rovings are broken; The purpose of the three methods is to break the spun yarn when one or more of the roving slivers is broken, thereby stopping spinning
