Guide roller structure for warp knitting machine carbon fiber yarns

Abstract

The invention discloses a guide roller structure for warp knitting machine carbon fiber yarns. The guide roller structure comprises a plurality of guide rollers. When the guide roller structure works, the carbon fiber yarns are unwound from a yarn storing mechanism, guided by the guide rollers and conveyed to a knitting mechanism for carrying out knitting, the guide rollers are divided into convex guide rollers with convex arc-shaped faces and a concave guide roller with a concave arc-shaped face, the convex guide rollers and the concave guide roller are arranged on guide roller supports respectively, the guide roller supports are arranged on a rack of a warp knitting machine, the convex guide rollers and the concave guide roller are arranged at intervals, and the carbon fiber yarns are conveyed to the knitting mechanism for conducting knitting after being guided by the convex arc-shaped faces of the convex guide rollers and the concave arc-shaped face of the concave guide roller. The guide rollers are preferably three in number and are composed of two convex guide rollers and one concave guide roller, and one convex guide roller is adjacent to the concave guide roller. The guide roller structure for the warp knitting machine carbon fiber yarns can effectively avoid the fact that the phenomena of swing from side to side and instability occur when the carbon fiber yarns pass through the guide rollers, and effectively prevents accidents of carbon fiber yarn twisting, fold and the like from occurring.

Description

technical field [0001] The invention relates to a carbon fiber yarn delivery mechanism of a warp knitting machine, in particular to a guide roller structure in the carbon fiber yarn delivery mechanism of a warp knitting machine. Background technique [0002] As an advanced composite material, carbon fiber has been widely used in various fields such as aerospace, nuclear energy equipment, transportation and stealth weapons. Carbon fiber not only has a series of excellent properties such as high specific strength and specific modulus, low thermal expansion coefficient, high temperature resistance, corrosion resistance, creep resistance and self-lubrication, but also has the characteristics of flexibility and weaving of fibers. [0003] Carbon fiber yarn is often used as a weaving material on a warp knitting machine to be guided by guide rollers. The existing guide roller structure for warp knitting machine carbon fiber yarn includes several guide rollers. The guide rollers are...

AI Technical Summary

Problems solved by technology

This kind of guide roller structure, because the guide roller is cylindrical and the carbon fiber yarn is flat, the carbon fiber yarn often swings left and right and is unstable when passing the guide roller, so accidents such as torsion and folding of the carbon fiber yarn often occur, which greatly affects weaving quality
