Two-for-one twisting type spinning frame

Abstract

The invention relates to a two-for-one twisting type spinning frame, and belongs to the technical field of textile. The two-for-one twisting type spinning frame has the advantages that a twisting andspinning mechanism of an ordinary ring spinning frame is changed into a two-for-one twisting winding mechanism, the two-for-one twisting winding mechanism comprises a two-for-one twisting mechanism and a winding mechanism, a twisting disc can rotate by a circle for silver operated in zones from jaws of a front roller to a tension device, accordingly, two-twist two-for-one twisting effects can be realized for the silver, and the twisting efficiency can be improved; the winding mechanism is positioned in a yarn storage tank of the two-for-one twisting mechanism, twisting components and winding components are substantially separated from one another, twisting and winding can be separately individually controlled, the twisting and winding mechanism, by which twisting and winding can be simultaneously carried out and are constrained by each other, of the ordinary ring spinning frame is thoroughly changed, large-package spun yarns of cheese can be formed, the shortcomings of great winding balloon and tension difference of the traditional spinning frame mechanisms and high fluctuation of the quality of existing resultant yarns can be overcome, and accordingly the quality and the uniformity of resultant yarns can be improved; the two-for-one twisting type spinning frame is reasonable in structure and convenient to operate, and popularization can be facilitated.

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. technical background [0002] 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 reason is tha...

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.
