Rough yarn pulling-type feeding-controllable spinning device

Abstract

The invention relates to a rough yarn pulling-type feeding-controllable spinning device. The rough yarn pulling-type feeding-controllable spinning device comprises a rear roller, a rear rubber roll, a middle roller, a middle rubber roll, a front roller and a front rubber roll. The rear roller comprises a rear roller shaft, and a rear roller sleeve is additionally installed on the rear roller shaft; four left insert holes are arranged in the circular face of the left end of the rear roller sleeve, and four right insert holes are arranged in the circular face of the right end of the rear roller sleeve; the left end stretching out of the rear roller sleeve along the rear roller shaft is provided with a left slideway in the length direction, and the right end stretching out of the rear roller sleeve along the rear roller shaft is provided with a right slideway in the length direction, a left pulling pin is additionally installed in the left slideway, and a right pulling pin is additionally installed in the right slideway; four left insert pins are additionally installed on the outer periphery of the left pulling pin at an equal-arc interval, and four right insert pins are additionally installed on the outer periphery of the right pulling pin at an equal-arc interval a left vertical pin is additionally installed in the center of circle of the left pulling pin, and a right vertical pin is additionally installed in the center of circle of the right pulling pin; and the left vertical pin is connected with the inner side surface of the closed left end of the rear roller shaft through a left telescopic pin, and the right vertical pin is connected with the inner side surface of the closed right end of the rear roller shaft through a right telescopic pin. During the spinning process, interrupted rotation control of the rear roller sleeve is achieved by means of extension and contraction of the left and right telescopic pins, control of interrupted feeding of rough yarns is achieved afterwards, and production of yarns having various fancy effects is achieved.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a roving pull-type controllable feeding and spinning device. 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 expression...

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
