Yarn guiding device of double-twisting machine

Abstract

The invention provides a yarn guiding device of a double-twisting machine. The yarn guiding device solves the problems that the tension of existing yarn guiding devices cannot be adjusted, textile threads are easily split into strands and broken at the ends, and the working quality is seriously affected. The position of a yarn guiding assembly is adjusted in the X-axis direction and the Z-axis direction through driving of vertical adjusting assemblies and a horizontal adjusting assembly easily and conveniently to make textile threads in a tension state and prevent the textile threads from being split into strands; driving rods are pushed by air cylinders to move in the X-axis direction, driving discs follow the driving rods to move in the X-axis direction, transmission blocks A and drivinggrooves cooperate with each other, transmission rods move in the Z-axis direction, and the adjustment of the position of the yarn guiding assembly in the Z-axis direction is completed; a main shaft is driven by a motor to rotate, a belt pulley follows the main shaft to rotate, friction is generated between a cable and the belt pulley to make the cable move, and the adjustment of the position of the yarn guiding assembly in the X-axis direction is completed; the product quality is improved through the yarn guiding assembly, a buffering function is achieved by utilizing springs, the tension fluctuation is reduced, and the end breakage phenomenon of the textile threads is reduced.

Description

Technical field [0001] The invention relates to the technical field of textile equipment, in particular to a yarn guide device of a two-for-one twister. Background technique [0002] In recent years, driven by strong market demand at home and abroad, the textile industry has developed rapidly, and its scale and economic benefits have continued to grow. The output of my country's main textile products, chemical fiber, yarn, cloth, etc., has shown a continuous growth trend, and its output has ranked first in the world. my country has become a veritable textile country, the industry's competitiveness has been continuously strengthened, and the international trade status has increased year by year. [0003] The two-for-one twister is an indispensable equipment in textile enterprises. The two-for-one twister is a kind of twisting equipment that can achieve one turn and two twists. The twisting efficiency is doubled compared with traditional twisting equipment. The yarn rotates at a high...

AI Technical Summary

Problems solved by technology

The existing two-for-one twisting machine yarn guide device is usually provided with an L-shaped yarn guide frame on the two-for-one twister, a yarn guide porcelain tooth is set on the L-shaped yarn guide frame, and a V-shaped gap is arranged on the yarn guide porcelain tooth, but this yarn guide The tension of the device cannot be adjusted, and the textile thread is prone to splitting and broken ends, which seriously affects the quality of work and causes poor textile effects.
