Compressing and drafting mechanism used for yarns

Abstract

The invention discloses a compressing and drafting mechanism used for yarns, and belongs to the field of textile processing mechanical equipment. Yarn compressing mechanisms are respectively symmetrically arranged on fixing brackets of two sides of the drafting mechanism vertically, a shaping revolving drum is rotatably connected with a fixing bracket arranged between a front yarn guiding roller and a back yarn guiding roller, and drafting guiding grooves are symmetrically formed in fixing brackets arranged at two sides of the shaping revolving drums; the drafting guiding grooves are internally slidably provided with drafting guiding plates, two ends of a drafting roller are respectively rotatably connected with the drafting guiding plates arranged at the two sides of the fixing brackets,an upper lifting rotary shaft and a lower lifting rotary shaft are in transmission connection through a yarn compressing chain, and an auxiliary yarn guiding roller and a main yarn guiding roller arehorizontally and rotatably connected to the fixing brackets in turn from top to bottom. The compressing and drafting mechanism is reasonable in structure, yarns can be efficiently and accurately transferred intermittently, the yarns are stably subjected to drafting, shaping and processing section by section during the transferring process, the automation degree of yarn processing is improved, andrequirements of production use are met.

Description

technical field [0001] The invention belongs to the field of textile processing machinery and equipment, and in particular relates to a compression and drafting mechanism for yarn, which is mainly used in the field of yarn shaping production and processing. Background technique [0002] With the development of the production industry and the improvement of people's living standards, people have higher and higher requirements for textile materials. High-end textiles can be woven from high-quality textile materials to meet people's needs. Textile materials refer to fibers and fiber products, which are specifically manifested as fibers, yarns, fabrics and their composites. In modern textiles, the research and development of new textile materials, especially the development and use of nanofibers, has broken through the traditional textile materials. Conceptually, textile materials have become an important component of soft matter materials. Yarn is an important textile material...

AI Technical Summary

Problems solved by technology

In the process of yarn production and processing, it is necessary to draft and set the dyed yarn, especially for the yarn with elastic texture, the drafting and setting is particularly important. During the stretching process, the heating cannot be performed synchronously during the drafting and setting process of the yarn, which affects the quality of the yarn setting, and it is difficult for the existing yarn drafting mechanism to draft the yarn in segments during the drafting process of the yarn. stretching, making it difficult for the yarn to be fully and efficiently drafted and shaped, which affects the quality of yarn production and processing, and cannot meet the needs of production and use
