Segmented drafting device for yarn

Abstract

The invention discloses a segmented drafting device for yarn, and belongs to the field of textile processing mechanical equipment. A driving mechanism and a drafting mechanism are horizontally and fixedly arranged on a transfer support from top to bottom in sequence, the two sides of a translation guide rod are slidably provided with a front reciprocating guide plate and a rear reciprocating guideplate in the horizontal direction respectively, one side of the front reciprocating guide plate is horizontally and rotationally connected with a front drafting rotation roll, and one side of the rear reciprocating guide plate is horizontally and rotationally connected with a rear drafting rotation roll. A yarn inlet press roll is horizontally arranged on one side of a yarn inlet rotation roll below a drafting support, a yarn outlet press roll is horizontally arranged on one side of a yarn outlet rotation roll, the two sides in the middle of a drafting screw rod are vertically and fixedly provided with a front rotary gear and a rear rotary gear respectively, and the driving mechanism is horizontally arranged on the portion, on the upper side of the drafting support, of the transfer support, wherein the dimensions of the front and rear rotation gears are equal. The segmented drafting device is reasonable in structural design, in the transfer process of the yarn, high-efficiency and stable segmented drafting of the yarn can be achieved, the yarn processing automation degree is improved, and the processing and using requirements are met.

Description

technical field [0001] The invention belongs to the field of textile processing machinery and equipment, and in particular relates to a segmented yarn drafting mechanism, which is mainly used in the continuous segmented drafting process of the yarn during transmission. 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 text...

AI Technical Summary

Problems solved by technology

During the production and processing of yarn, it is necessary to pull and shape the bleached and dyed yarn, especially for the yarn with elastic texture. During the pulling process, it is difficult to efficiently and smoothly pull the yarn into segments, which affects the quality of the yarn pulling and shaping. Moreover, the existing driving mechanism for yarn pulling has a complicated structure and troublesome operation, and it is difficult to continuously and accurately drive the pulling process. The reciprocating translation of the stretching roller affects the efficiency and quality of the yarn drafting process, which cannot meet the needs of production and use
