Three-roving controlled feeding spinning device and three-roving controlled feeding spinning method

Abstract

The invention provides a three-roving controlled feeding spinning device and a three-roving controlled feeding spinning method. The three-roving controlled feeding spinning device comprises a rear roller traction pair composed of a rear roller and a rear rubber roller, a middle-rear roller traction roller composed of a middle-rear roller and a middle-rear rubber roller, a middle-front roller traction pair composed of a middle-front roller and a middle-front rubber roller, and a front roller traction pair composed of a front roller and a front rubber roller, wherein a rear rubber roller shaft and a middle-rear rubber roller shaft are respectively connected with three rubber gaskets by circular lifting pins. When spinning is implemented, tight pressing or suspended contact between the rubber gaskets and the rollers is realized by the lifting of the lifting pins, then the controlled feeding and corresponding selectivity of the corresponding traction area of three roving can be realized, subsequently, single-color, bi-color and three-color structured yarns with different effects can be achieved, the varieties of the yarns are enriched, and the additional value of the yarns is increased.

Description

technical field [0001] The invention relates to the technical field of spinning, and in particular relates to a spinning device and spinning method with three rovings controllable feeding. Background technique [0002] With the continuous advancement of the times, people's requirements for clothing materials continue to increase. At present, the textile and clothing industry is in an era of pursuing fashion, diversification and high quality. Therefore, new requirements have been put forward for the development of textile raw materials, among which fancy yarns have gradually entered people's field of vision and occupy an irreplaceable position. Fancy yarn refers to the yarn with special structure and appearance effect obtained by processing fiber or yarn with special raw materials, special equipment or special technology in the process of spinning and thread making. It is a decorative yarn in yarn products. A kind of yarn that works. Fancy yarn has unique structure, flexibl...

Problems solved by technology

The modification cost of this method is lower and the efficiency is higher, but the evenness of yarn dryness is poor

In view of this, in the Chinese patent "Segment Color Spinning Transmission Device (Patent No.: ZL200420081737.2)", a segment color yarn production device with four loops is provided, but this device still uses double roving feeding, and at the same time , the first roller and the second roller are still controlled by the same motor, so the main draft cannot be adjusted freely
