A cashmere/yak cashmere segment colorful slub yarn production device and production method

Abstract

The invention provides a cashmere / yakwool section color necked yarn production device and method. The production device comprises a front roller, a middle roller and a rear roller. A front connecting gear is additionally arranged at the right end of a front roller shaft, connecting teeth are evenly distributed on one circumference of the surface of the front connecting gear, an upper middle connecting gear and a lower middle connecting gear are additionally arranged at the right end of a middle roller shaft, the upper middle connecting gear is connected with the front connecting gear in a tight matched mode, connecting teeth are evenly distributed on one circumference of the surface of the upper middle connecting gear, connecting teeth are evenly distributed on one half of the circumference of the lower middle connecting gear, and no connecting tooth is arranged on the other half of the circumference of the lower middle connecting gear. A rear connecting gear is additionally arranged at the right end of the rear roller shaft, connecting teeth are evenly distributed on one circumference of the rear connecting gear, the rear connecting gear is connected with the lower middle connecting gear in a tight matched mode, and therefore intermittent feeding of yakwool rough yarn is achieved. A servo system needing to be additionally arranged in a section color device is omitted, the improvement cost is reduced, and meanwhile production of cashmere / yakwool section color necked yarn with natural characteristics is achieved.

Description

technical field [0001] The invention relates to the new technology field of ring spinning, in particular to a cashmere / yak cashmere section colorful slub yarn production device and production method. Background technique [0002] Segment colored yarn is a kind of fancy yarn, which is spun with fibers of different colors or raw materials. The color of the yarn is composed of a variety of colored fibers in the same cross section of the yarn. The fibers are in an irregular and intermittently changing distribution state. Duancai yarn fabric has soft and plump color, various patterns and strong sense of hierarchy, satisfying consumers' pursuit of fashion. At present, there are mainly four types of segment-colored yarn production technologies that are mainly used at home and abroad. These four segment-colored yarn production technologies all need to install a segment-colored yarn device on the corresponding production equipment, that is, a computer program controller to control ...

AI Technical Summary

Problems solved by technology

This mechanism can spin segment colored yarn with relatively evenness, but the adjustment and control of the roving weight and the draft ratio in the rear area are not convenient enough.

At the same time, the current segment-colored yarn production devices are realized by using a separate servo drive for the rollers of the spinning frame. Therefore, if the existing old machine is modified, a servo control system needs to be added again, which will increase the cost of the modification.
