Sectional warping machine and yarn storing, yarn feeding and leasing system thereof

Abstract

The invention discloses a yarn storing, yarn feeding and leasing system of a sectional warping machine. The system is characterized in that a yarn storing unit, a yarn feeding unit and a leasing unit which are sequentially arranged are included; the yarn storing unit comprises a long stand column, an upper yarn storing roller arranged on the long stand column, a short stand column, a lower yarn storing roller arranged on the short stand column and a linear driving device used for driving the upper yarn storing roller and the lower yarn storing roller to vertically rise and fall; the yarn feeding unit comprises a box, a yarn pressing rubber roller and a yarn guiding roller which are arranged on the box, a driving device d used for driving the yarn guiding roller to rotate and a reciprocating mechanism used for driving the yarn pressing rubber roller to abut against and be separated from the surface of the yarn guiding roller; the leasing unit comprises wallboards, linear guide rails, a leasing reed and a three-segment driving device used for driving the leasing reed to slide on the linear guide rails. Accordingly, the same length and equal tension among yarn and among strips during sectional warping are guaranteed through the yarn storing unit, the yarn feeding unit and the leasing unit, and the sheet yarn tension also can be strictly controlled when broken ends are processed.

Description

technical field [0001] The invention relates to the technical field of warping, and more specifically relates to a yarn storing, feeding, and twisting system of a section warping machine. Background technique [0002] The warping machine is a textile machine that draws the yarn from the bobbin on the creel and winds it in parallel and evenly on the warp beam or weaving beam according to the specified length for sizing or weaving. During warping, the warp yarns must have appropriate tension, while maintaining the strength and elasticity of the warp yarns as much as possible. During the warping process, the tension of the warp yarns should be as uniform as possible. Round and upright, no unevenness. [0003] The section warping machine divides the entire yarn into multiple strips and winds it on the drum evenly through multiple warping, and then performs the second warping (that is, reversing the shaft) to wrap the entire yarn on the drum at one time. A textile machine wound...

AI Technical Summary

Problems solved by technology

[0004] At present, due to the structural principle of the creel, the yarn on the bobbin is passively unwound. It is difficult for the existing section warping machine to accurately control the tension of each yarn to keep the same, and it is difficult to ensure The length is consistent. In addition, in the case of unexpected situations such as yarn breakage, the yarn loses tension control, and the error of tension and winding length is even greater.
