Wool yarn twisting apparatus

Abstract

The invention provides a wool yarn twisting apparatus and belongs to the technical field of weaving machinery. The wool yarn twisting apparatus comprises a twisting mechanism and a yarn collecting mechanism, wherein pins of the twisting mechanism are arranged on the lower end of a driving round disc along the periphery at equal intervals; the top ends of a first left twisting roller, a second right twisting roller, a second left twisting roller and a second right twisting roller are respectively provided with a swinging rod; the external end of the swinging rod is tightly close to the corresponding pin; one end of a reset spring is fixed on a bearing support plate and the other end is installed on the swinging rod; the yarn collecting mechanism is formed by a rack, a yarn guide assembly and a yarn collecting assembly; a yarn guide bearer of the yarn guide assembly can left-right slidalbly arranged on a guide rail; a yarn guide ring is installed on the yarn guide bearer; an adjustable lead screw can be rotationally arranged on the rack; the adjustable lead screw is in a threaded connection with the yarn guide bearer; and a yarn collecting roller of the yarn collecting assembly can be rotationally arranged on the rack. Wool yarns can be quickly twisted; great effect can be achieved; and the wool yarn twisting apparatus is simply structured and requires low cost.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a yarn twisting device. Background technique [0002] Wool spinning is the spinning process in which wool fibers are processed into yarn. The wool fiber is mainly wool, and also includes special animal hairs such as cashmere, rabbit hair, mohair, and yak hair. The wool spinning process can also be used for wool-type chemical fiber pure spinning, blending and blending with other natural fibers. Wool fabrics, knitted fabrics, blankets, etc. woven with pure and blended wool yarns have the characteristics of warmth retention, moisture absorption, elasticity and wear resistance. The main process of wool spinning is: firstly, raw materials such as wool fiber and chemical fiber are mixed according to the wool blending ratio set by the product, and then the wool spinning roller carding machine combs and removes impurities from the mixed and oiled wool fiber to form a wool net...

AI Technical Summary

Problems solved by technology

At present, the common twisting devices rely on the upper and lower twisting nets to twist the wool yarn. The back and forth swings of the upper and lower twisting nets are realized by their respective swing cylinders or crank linkage mechanisms. This structure is relatively complicated and costly.
