A kind of roving control feeding spinning device and spinning method

Abstract

The invention provides a rough yarn control feeding spinning device and method. The device is composed of single-spindle spinning devices. The number of the single-spindle spinning devices is 200-510. Each single-spindle spinning device comprises a rear drawing roller pair composed of a rear roller and a rear rubber covered roller, a middle drawing roller pair composed of a middle roller and a middle rubber covered roller and a front drawing roller pair composed of a front roller and a front rubber covered roller, wherein the middle roller and the front roller each comprise a solid cylindrical roller shaft, the roller shafts of the single-spindle spinning devices are fixedly connected, roller sleeves are fixedly connected to the roller shafts corresponding to the single-spindle spinning devices, the rear, middle and front rubber covered rollers of each single-spindle spinning device are independent, the rear roller of each spindle adopts a loop roller sleeve or a fixed roller sleeve controlled by an electromagnet, controllable feeding of rough yarn is achieved, and then production of yarn of various fancy effects is achieved, so that varieties of yarn are added, and meanwhile the comprehensive quality of resultant yarn is improved.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a roving controllable feeding spinning device and spinning method. 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, flexible shape, rich color expr...

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
