A kind of segment color slub yarn production device and production method

Abstract

The invention discloses a production device and method for segment-color bunchy yarns. The production device comprises a front roller, a middle-front roller, a middle-rear roller and a rear roller, a full-tooth front connection gear is additionally installed at the right end of a front roller shaft, a first middle-front connection gear and a second middle-front connection gear are additionally installed at the right end of a middle-front roller shaft, the first middle-front connection gear is tightly connected with the front connection gear in an engaged mode, a first middle connection gear is in a full-tooth form, connecting teeth are uniformly distributed on the 2 / 3 circumference of the second middle-front connection gear, the 1 / 3 circumference is smooth, and a first middle-rear connection gear and a second middle-rear connection gear are additionally installed at the right end of a middle-rear roller shaft; the first middle-rear connection gear and the second middle-front connection gear are tightly connected in an engaged mode, the first middle-rear connection gear is in a full-tooth form, connecting teeth are uniformly distributed on the 2 / 3 circumference of the second middle-rear connection gear, the 1 / 3 circumference is smooth, and a full-tooth rear connection gear is additionally installed at the right end of a rear roller shaft and tightly connected with the second middle-rear connection gear in an engaged mode. In this way, rough yarns are fed in an intermitted mode, a servo system needing to be additionally installed on a segment-color device is omitted, and the cost for modification is lowered.

Description

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

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.
