Spinning machine compact spinning drafting system

Abstract

This invention relates to a close spinning drafting device of the spun yarn machine for the cotton spinning and wool spinning, which is composed of the drafting reel cage, the decollation wind-engaging device, the up spin, the middle and up roller, the middle and down roller, the up spin, the up rubber ring, the front and down roller, the front and up roller, the roller backing board and so on, the vertical clamp right roller and the vertical clamp left roller are fixedly mounted on the front of the horizontal clamp which is composed of a pair of the up roller and the down roller, wherein the vertical clamp is composed of the vertical clamp right roller and the vertical clamp left roller, the driving gear is mounted on the vertical clamp right roller, and the driving chain is composed of the driving gear and the driving device of the spun yarn machine, which is vertical mutually through the vertical clamp and the horizontal clamp to make the sliver receive mechanical extrusion from the up, the down, the left and the right direction, the mightiness of the twist yarn is high, the filoplume is fewer. This device can improve the quality of the yarn effectively.

Description

1. Technical field [0001] The invention relates to a spinning machine part, which is a drafting device for cotton and wool spinning machines suitable for spinning spun yarns. 2. Background technology [0002] Existing ring spinning frames at home and abroad all have horizontal jaws, and the roving strands are drawn through three or four passes. The whiskers of the horizontal jaws continue to widen, so that the whiskers output from the front jaws are too wide. When the twist is transferred to the twisting triangle, the edge fibers are likely to cause flying flowers and hairiness. The design of the front drafting zone has poor ability to control the fibers, and the floating zone is too long, so that the fiber speed change points in the drafting cannot be concentrated at the front. The middle and upper iron rollers are driven by the friction of the upper and lower aprons, and the upper aprons produce serious slippage, which reduces the evenness of spinning. 3.

AI Technical Summary

Problems solved by technology

The whiskers of the horizontal jaws are continuously widened, so that the whiskers output from the front jaws are too wide, and when the twist is transferred to the twisting triangle, the edge fibers are likely to cause fly and hairiness

The design of the front drafting area has poor ability to control the fibers, and the floating area is too long, so that the fiber speed change points in the drafting cannot be concentrated in the front

The middle and upper iron rollers are driven by the friction of the upper and lower rubber rings, and the upper rubber rings will cause serious slippage, which will reduce the evenness of spinning
