Distance block structure of upper pin of spinning frame

Abstract

The invention relates to a distance block structure of an upper pin of a spinning frame, which is characterized by comprising a pressure rod and a distance block, wherein the pressure rod and the distance block are integrally formed; the middle part of the pressure rod is tightly connected with the front lateral part of the distance block; balance blocks are respectively arranged on two sides of the distance block under the pressure rod; and the lateral side and the top end of each balance block are respectively and tightly jointed with the distance block and the pressure rod. Each balance block adopts a triangular cone. The pressure rod adopts a metal rod; the balance blocks and the distance block are made of plastics; and the balance blocks, the distance block and the middle part of the pressure rod are integrally formed in an injection molding manner. A clamping groove is formed at the middle part on the rear side of the distance block. The distance block structure is simple and reasonable; the front part of the upper pin of the spinning frame is lengthened through respectively arranging the balance blocks on the left and the right of the distance block under the pressure rod, so that fibers in a pelagic region are effectively controlled, and the spinning quality is improved. Moreover, the operation stability is improved; and the distance block can not swing during the operation and has good stability, thereby improving the spinning quality.

Description

technical field [0001] The invention relates to a textile machinery accessory, in particular to a spacer structure for upper pins of a spinning frame that can lengthen the front portion of the upper pins of a spinning frame, and belongs to the technical field of textile machinery. Background technique [0002] With the improvement of the quality of life, people are more and more particular about clothing. When buying clothes, a little flaw may cause consumers to cancel their desire to buy. Therefore, the requirements for product quality are getting higher and higher. The upper pin is one of the key components in the drafting system of the spinning frame, and its shape and structure will directly affect the yarn quality of the spinning frame. The front end of the upper pin of the spinning frame is clamped with an upper pin spacer, but at present, the front part of the upper pin of the spinning frame is too short, so that the front control point of the upper pin is too far awa...

AI Technical Summary

Problems solved by technology

The front end of the upper pin of the spinning frame is clamped with an upper pin spacer, but at present, the front part of the upper pin of the spinning frame is too short, so that the front control point of the upper pin is too far away from the jaw during use, so that the floating area The short fibers are not well controlled. These short fibers are squeezed and rubbed by the surrounding fast and slow fibers, making them shift in advance or lag behind, which affects the quality of the spun yarn

In addition, during operation, the distance block will shake and the stability is not good, which will further affect the quality of spun yarn
