Abstract

The invention discloses a weft drawing device of an air jet loom. The weft drawing device comprises a controller, a shears mechanism, an air flow guiding tube, a driven pressing wheel mechanism, a driving rotating wheel mechanism, a yarn detecting sensor, a waste yarn suction port, an air source and a guiding nozzle. The shears mechanism comprises a shears air cylinder, shears and a guiding frame, wherein the shears air cylinder is connected with the guiding frame, and the guiding frame is provided with a shears sliding groove. The driven pressing wheel mechanism comprises a driven pressing wheel air cylinder and a driven pressing wheel. The driving rotating wheel mechanism comprises a driving rotating wheel motor and a driving rotating wheel. A waste yarn gap is formed between the driving rotating wheel and the driven pressing wheel. The position of an outlet of the guiding nozzle is matched with the position of an inlet of the air flow guiding tube, a main nozzle is arranged between the guiding nozzle and the air flow guiding tube, waste yarn penetrates through out of a spout of the main nozzle, and the yarn detection sensor is arranged at an outlet of the air flow guiding tube. The guiding nozzle, the driven pressing wheel air cylinder, the waste yarn suction port and the shears air cylinder are connected with the air source respectively. The weft drawing device is capable of automatically drawing the waste yarn out and high in reliability, saves time and labor and improves efficiency of the loom.

Description

technical field [0001] The invention relates to the technical field of textile machinery and equipment, in particular to a weft pulling device of an air-jet loom. Background technique [0002] With the development of the textile industry and the increase of labor costs, it is becoming more and more important for textile enterprises to improve the efficiency of looms and reduce labor costs. When the loom is running normally, weft stop is one of the important factors that limit the efficiency of the loom and reduce labor costs. When the weft of the loom stops, it is necessary to manually extract the weft yarn, which is time-consuming and laborious. The weft drawing device of the air-jet loom in the prior art adopts a winding weft drawing method, the waste yarn is easy to form coils, the removal channel is easy to block, the waste yarn removal is difficult and dirty, the degree of automation is low, and the efficiency is low. Contents of the invention [0003] The objec...
