Segment-colored slub yarn production device and production method with controllable slub length

Abstract

Provided is a production device and production method of segment color slubby yarn of which a length of a bamboo joint is controllable. The production device comprises a front roller, a middle roller and a rear roller, the right end of a shaft of the front roller is additionally provided with a full tooth front collecting gear, the right end of a shaft of the middle roller is additionally provided with a first middle connecting gear and a second middle connecting gear, the first middle connecting gear is connected to the front collecting wheel in a closely fitted mode, the first middle connecting gear is full teeth, the second middle connecting gear is divided into 2N equal parts with a uniform angle clockwise, wherein completely identical connecting teeth are evenly distributed at the external circumferences of N equal parts, the external circumferences of the other N equal parts do not have connecting teeth and are in a smooth state, each equal part of external circumference with the connecting teeth and each equal part of external circumference without the connecting teeth are alternately arranged, the right end of a shaft of the rear roller is additionally provided with a full tooth rear collecting gear, the rear collecting gear is connected to the second middle connecting gear in a closely fitted mode, accordingly intermittent thick yarn feeding is achieved, and meanwhile lengths of a base yarn section and bamboo joint colorful yarn section are decided by N and thus are adjustable.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a production device and method for segment-colored slub yarn with controllable slub length. 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 t...

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.
