Wrapped bunchy yarn production apparatus

Abstract

The invention discloses a wrapped bunchy yarn production apparatus, which comprises a front roller, a middle roller and a rear roller; a middle roller shaft and a rear roller shaft are connected by a gear and then driven by a servo motor; a front roller shaft is driven by a main motor; a staple fiber rove is fed in from the rear roller and is stretched to obtain a staple fiber strip that is output from a front roller jaw; a staple fiber spun yarn is fed in from the front roller and merged with the staple fiber strip that is obtained at the front roller jaw after being stretched. A base yarn is produced in a way that the main motor drives the front roller rotate at a rotating speed v1; the servo motor drives the middle roller rotate at the rotating speed v2; and the rear roller rotating speed v3=kv2, wherein, k is determined by the gear teeth number; a ring is produced in a way that the main motor drives the front roller rotate at the rotating speed v1; the servo motor drives the middle roller rotate at the rotating speed v4; and the rear roller rotating speed v5=kv4, wherein, v4 is larger than v2. A twist transmitted from bottom to the top makes the staple fiber strip rotate around its own shaft to obtain a bunchy yarn, at the same time, the staple fiber spun yarn is wrapped on the surface of the bunchy yarn continuously, thereby obtaining the wrapped bunchy yarn.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a wrapping slub yarn production 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, diversified use of ...

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 given, but the 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
