Siro-segment color yarn production device and production method

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 a production method for Siro-segment colored yarn. Background technique [0002] Duan Cai Yarn is a kind of fancy yarn. It uses fibers of different colors or raw materials for spinning. Its color is composed of multiple colored fibers in the same cross-section of the yarn. In the longitudinal length of the yarn, different combinations of colored fibers are used. The fibers are distributed irregularly and intermittently. Duancai yarn fabrics are soft and full in color, diverse in fancy styles, and strong in layering, which can satisfy consumers' pursuit of fashion. At present, there are mainly four kinds of segment color yarn production technologies that are mainstream used at home and abroad, namely, the needle comb drawing process for segment color matching, the drawing frame segment feeding, the three-roller spinning frame, and the four-roller spin...

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
