Twisting machine used for compound double twisting

Abstract

The invention relates to a twisting machine, in particular to a twisting machine used for compound double twisting. The twisting machine comprises a frame, wherein the frame is provided with a driving transmission mechanism, at least one twisting device and a yarn winding device corresponding to the twisting device; the twisting device contains at least two double twisting spindles and one compound twisting spindle, the double twisting spindles are parallel to each other and fixed on the mounting plate of the compound twisting spindle; a first-twist bolster is fixed on the mounting plate, a compound twisting spindle whorl is driven by the driving transmission mechanism, the compound twisting transmission wheel is connected with a a first-twist spindle whorl which rotates in the reverse direction of the compound twisting transmission wheel, through a transmission belt; and parallel grooves are arranged on the external circumference of at least one of the compound twisting transmission wheel and the first-twist spindle whorl. The invention mainly provides the twisting machine used for compound double twisting which has simple structure and can perform four processes to multiple strands of raw material yarn on the same platform simultaneously, namely first-twist and double twisting, combination, compound twisting and double twisting in reverse direction, and winding; the production process flow is greatly shortened, the working time is reduced, the production cost is saved, the yarn quality is remarkably increased; and the technical problems of the prior art that the twisting machine can only perform one process, the structure of the integrated twisting machine is huge and complicated and the degree of twist is inconvenient to adjust, can be solved.

Description

technical field [0001] The invention relates to a twisting machine, in particular to a compound two-for-one twisting twisting machine. Background technique [0002] In the textile industry, yarn generally needs to be turned into a usable finished thread through primary twisting and double twisting. The two-for-one-twisting spindle that emerged at the end of the 20th century is a major improvement. Compared with the single-twisting spindle that was commonly used in the textile industry in the past, it greatly improves the productivity of spinning yarn and reduces the initial investment of the textile factory. At present, the existing two-for-one twisting spindles can only complete single-yarn primary-twisting two-for-one-twisting or double-twisting the multi-strand yarns combined by the doubling machine, and it is impossible to complete single-yarn primary-twisting and two-for-one twisting at one time on the same machine. , Multi-strand merging and double-twisting in the opp...

Problems solved by technology

[0003] The present invention mainly provides a simple structure, which can complete the primary twisting, double-twisting, merging, reverse-direction double-twisting and tube forming of multiple raw material yarns on the same machine, which greatly shortens the production process and reduces the Operating man-hours saves production costs and significantly improves yarn quality. The twisting machine with four kinds of processes can be completed at one time; The structure of the thread machine is huge and complicated, and the technical problem of inconvenient adjustment of the twist ratio
