A kind of production device and production method of two-color segment colored yarn

Abstract

The invention provides a double-color-section color yarn production device and a production method. The production device comprises a front roller, a middle front roller, middle rear roller and a rear roller, wherein a front connecting gear is added to the right end of a front roller shaft, connecting teeth are uniformly distributed on one circumference of the surface of the front connecting gear, first, second and third middle connecting gears are added at the right end of a middle front roller shaft, the first middle connecting gear is in tight and meshed connection with the front connecting gear, connecting teeth are uniformly distributed on one circumference of the surface of the front middle connecting gear, connecting teeth are uniformly distributed on one half circumference of each of the second middle connecting gear and the third middle connecting gear, the other half circumference is not provided with connecting teeth, a middle rear connecting gear and a rear connecting gear are added to the right end of a middle rear roller shaft and the right end of a rear roller shaft, connecting teeth are uniformly distributed on one circumference of the surface of each of a middle rear connecting gear and a rear connecting gear, the middle rear connecting gear and the rear connecting gear are in tight and meshed connection with the second middle connecting gear and the third middle connecting gear, interrupted feeding of rough yarns is achieved, a servo system required to be added in a sectioned coloring device is omitted, and the improvement cost is reduced.

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 double-color colored 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.
