A kind of production device and production method of Siro segment colored yarn

Abstract

The invention provides a siro-segment color yarn production device and production method. A cotton-feeding roller is mounted at the rear portion of a rear roller and includes a roller shaft. A roller bushing is connected onto the roller shaft through bearings. One bearing is controlled to be in the on or the off state through an electromagnetic switch. A sleeve is fixedly connected to the outside of the roller bushing. The lengths of the roller shaft, the roller bushing and the sleeve decrease in order. The distances between the roller bushing and both ends of the roller shaft are equal. The distances between the sleeve and the both ends of the roller bushing are equal. The roller shaft, the rear roller, and a middle roller are respectively driven by a first server motor, a second server motor and a third server motor. The electromagnetic switch and the three server motors are connected through a programmable logic controller. During spinning, a first rove and a second rove are fed through the roller shaft at both ends of the roller bushing, a third rove and a fourth rove are fed through the roller bushing at both ends of the sleeve, and the corresponding server motors control the roller rotating speed to realize the siro spinning type interrupted feeding of the four roves.

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 colored yarns of siro segments. 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 op...

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.

Three-roller spinning frame and four-roller spinning frame section colored yarn production device are only suitable for producing section colored yarn of two-color roving, the yarn color is relatively single, and the adjustment of color cycle is not flexible enough, and the dry quality of yarn needs to be improved
