A two-for-one twist spinning frame

Abstract

The invention relates to a two-for-one twist spinning frame, belonging to the technical field of textiles. In the present invention, the twisting and winding mechanism of the ordinary ring spinning frame is changed into a two-for-one twisting and winding mechanism. The two-for-one-twisting and winding mechanism is composed of a two-for-one twisting mechanism and a winding mechanism. The yarn sliver is rotated once by the twisting disk, and the yarn obtains two times twisting effect, which improves the twisting efficiency; the winding mechanism is located in the yarn storage tank of the two-for-one twisting mechanism, and the twisting part and the winding part Separation, twisting and winding are controlled separately, completely changing the twisting and winding mechanism of the ordinary ring spinning frame where twisting and winding are carried out simultaneously and mutually restricted, not only realizes the formation of large package spun yarns, but also eliminates the The traditional spinning machine mechanism has large differences in winding balloon and tension, and the yarn quality fluctuates greatly, thereby improving the yarn quality and uniformity. The invention has reasonable structure, convenient operation and easy popularization.

Description

technical field [0001] The invention relates to a spinning frame, in particular to a two-for-one twist spinning frame, which belongs to the technical field of textiles. [0002] technical background [0003] Spinning is the process of orderly arranging the messy loose fibers in sequence, such as opening, carding, drafting, etc., and then performing linear convergence and twisting. Different twisting methods directly determine the structure and efficiency of the yarn produced by spinning. Usually, the twist spinning forms are divided into two types: holding end twisting and free end twisting. Twisting at the holding end can limit the control of fiber strands for mandatory cohesion and twisting, and has the advantages of high cohesion between fibers, high yarn strength and good wear resistance, such as ring spinning technology with large quantity and wide range twisted form. However, the speed of ring spinning is low, generally more than ten meters per minute. The main reaso...

AI Technical Summary

Problems solved by technology

The technology of this device is essentially to add a drafting mechanism and a roving hanging mechanism to the yarn storage tank on the stationary spindle of the two-for-one twisting mechanism; because the roving package is long and the drafting system is complicated, the device is difficult to operate when spinning. The large yarn balloon affects the yarn quality, resulting in poor practicability and low application and promotion value of this technical device

Therefore, there is currently no technology to solve the contradiction between high-speed spinning and twisting of spun yarn and high-quality production, and the technical problem that the spinning frame cannot be packaged.
