Pressurizing device of big-tapered spindle of yarn twisting and rewinding machine

Abstract

The invention discloses a pressurizing device of a big-tapered spindle of a yarn twisting and rewinding machine. The pressurizing device is composed of a spindle body, a cylindrical spindle base, a spindle arm holding frame, first balance weight iron and a pressurizing assembly, wherein the spindle body makes close contact with a groove drum 1. The pressurizing assembly is composed of L-shaped flat iron and second balance weight iron. The short end of the L-shaped flat iron is connected with the first balance weight iron, the second balance weight iron 7 is fixedly arranged on the upper surface of the long end of the L-shaped flat iron, and the gravity center of the second balance weight iron 7 is located over the gravity center of the spindle body 2. By means of the technical scheme, the pressurizing device is simple in structure, low in cost, economical and practical and effectively solves the problems that the small end of the bobbin yarn is soft and protrudes and gauze at the two ends is formed bad when the spindle with the taper more than 9 degrees carries out yarn twisting and rewinding, the spindle is prevented from shaking during winding, the forming effect is good, the product quality is guaranteed, the subsequent procedure production is facilitated, and the needs of clients are met.

Description

technical field [0001] The invention relates to a structural design of a textile machinery spindle, in particular to a pressurizing device for a large-tapered spindle of a hank rewinding machine. Background technique [0002] The post-processing process of cotton textile enterprises has advanced by leaps and bounds since the 20th century. With the SSM loose winder and hank rewinder put into production, some technological changes in this field have entered the fast lane, especially the winding forming technology. In the field, its innovation has epoch-making significance, that is, the single-spindle transmission mode controlled by stepping motors quickly occupied the middle and high-end market of mercerized cotton hank yarn. In the past, the skein rewinding machine was produced on the 1332PD type machine modified from the 1332MD type winding machine. The yarn was passively wound into a uniform and strong bobbin for the subsequent process, that is, the anti-folding groove drum...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a pressurizing device for the large-tapered spindle of the skein rewinding machine. The pressurizing device is simple in structure, low in cost, economical and applicable, and effectively solves the problem of rewinding the large-tapered spindle above 9°. The small end of the bobbin yarn is soft, raised, and the ends of the yarn are poorly formed, which avoids the shaking of the bobbin during winding, and the forming effect is good, ensuring product quality.
