Three-color-section color yarn spinning device and spinning device

Abstract

The invention provides a three-color-section color yarn spinning device and a spinning device. The rear portion of a rear roller is additionally provided with a feeding roller, the feeding roller comprises a roller shaft, three roller sleeves are connected to the roller shaft, each roller sleeve is connected with the roller shaft through bearings, the bearings have two work states, namely the opening state and the closing state, the two states are controlled through electromagnetic switches, the roller shaft is driven by a first servo motor, the rear roller and a middle roller are driven by a second servo motor and a third servo motor respectively, and the three electromagnetic switches are connected with the first servo motor, the second servo motor and the third servo motor through a programmable logic controller. In the production process, rough yarn of three different colors are fed through the three roller sleeves, the rotating speed of the rear roller is the same as the rotating speed of the feeding roller, three states exist, and the first state is that three pieces of rough yarn are fed at the same time, and the three bearings are in the closed state; the second is that two pieces of rough yarns are fed at the same time, two bearings are in the closed state, and the other bearing is in the open state; the third state is that a single piece of yarn is fed, two bearings are in the open state, and the other bearing is in the closed state.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a spinning device and spinning method for three-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 operating cy...

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
