A roving electromagnetic controllable feeding spinning device and spinning method

Abstract

The invention provides a rove electromagnetic controllable feeding spinning device and a spinning method; the spinning device comprises a rear drawing roller pair formed by a rear roller and a rear rubber roll, a middle drawing roller pair formed by a middle roller and a middle rubber roll, and a front drawing roller pair formed by a front roller and a front rubber roll; the rear roller shaft is fixedly sleeved by a middle sleeve; the middle sleeve is sleeved by a rear roller sleeve; the inner surface of the rear roller sleeve and the outer surface of the middle sleeve are connected in a slide manner; an electromagnet is added in the middle sleeve, and controlled by an electromagnetic switch; the first rove is pressed and fed between the rear rubber roll and the rear roller sleeve; the second rove is pressed and fed between the first middle rubber roll sleeve of the middle rubber roll and the middle roller sleeve; the third rove is pressed and fed between the third middle rubber roll sleeve of the middle rubber roll and the middle roller sleeve; the electromagnetic switch is opened and closed to realize interrupted rotary control of the rear roller sleeve, thus feeding the first rove in an interrupted manner, and producing yarns of various pattern effects.

Description

Technical field [0001] The invention relates to the technical field of spinning, in particular to a roving electromagnetic controllable feeding spinning device. Background technique [0002] With the continuous advancement of the times, people's requirements for clothing fabrics continue to increase. At present, the textile and clothing industry is in an era of pursuit of 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 vision and occupy an irreplaceable position. Fancy yarn refers to the yarn with special structure and appearance effect obtained by using special raw materials, special equipment or special technology to process the fiber or yarn in the process of spinning and thread making. It is a decorative yarn product. The role of a yarn. The unique structure, flexible shape, rich color performance, diversified use of raw material...

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
