Description

A Siro Spinning Rotary Separation Pressure Rod Spacer

technical field

The utility model relates to a siro spinning rotary separation type pressure rod spacer, which belongs to the technical field of textile processing.

Background technique

The two rovings of siro spinning are drafted separately and then twisted together. Due to the combined effect, it has a more obvious effect on improving evenness and reducing thick and fine details. Due to the particularity of the yarn forming process, the Siro yarn has the characteristics of less hairiness, good evenness, smooth surface, round cross section, etc. During the stretching process of the yarn, the fibers in the ring spinning single yarn are closely entangled with each other. The degree and cohesion are lower than those of siro-spun single yarn. Because the two rovings are fed in parallel and the spacing is large, the twisting triangle area of the spun yarn is large and the twist transmission is poor, especially the variety with a small twist will cause more escaped fibers and more yarn details, and it is easy to cause the two single yarns One or two severed ends. Especially when high-count yarns are spun by siro spinning technology, the situation of single end breakage is more serious. Mechanisms are prone to overlapping strands, resulting in reduced yarn quality.

A spacer for upper pin pressure rods on spinning frames, publication number CN202543440U, published on November 21, 2012, discloses a spacer for upper pin pressure rods on spinning frames, the utility model relates to the technical field of spinning frames, and specifically discloses a A spacer for upper pin pressure rods on spinning frames, the upper pin pressure bar spacers on spinning frames include pressure rods and spacers installed on the pressure bars, and are set in the middle of the rear side of the spacers There is a groove, and the distance block is fixedly connected with the pressure bar. In the utility model, the distance block described in the upper pin pressure bar spacer block of the spinning frame is fixedly connected with the pressure bar, which has a blocking effect on the progress of the strands during drafting and affects the fibers in the strands. This affects the evenness of the yarn evenness, and there is no control mechanism for the siro spinning sliver, which cannot solve the problem that the two siro spinning slivers overlap.

A pressurized separation type pressure bar spacer, publication number CN103397413B, published on January 6, 2016, discloses a pressurized separation type pressure bar spacer, this invention belongs to the field of textile processing technology, specifically discloses A pressurized and separated pressure bar spacer, the pressurized separated pressure bar spacer includes a spacer and a pressure bar, and the pressure bar is a whole piece, which is movable in the spacer, and the pressure bar The outer surface of the straight teeth is evenly distributed, and the area of the straight teeth is as wide as the width of the front top roller. There is a positioning groove at the center of the length of the pressure rod, and the positioning pin is fixed on the distance block. The head of the positioning pin is placed in the positioning in the slot. The pressure rod has the function of reducing the blocking effect of the pressure rod on fiber movement when the strands are drawn, but because the strands are forcibly separated into small cotton bundles, it cannot be applied to the requirement of Siro spinning to isolate two strands.

Contents of the invention

In view of the above existing problems, the purpose of this utility model is to provide a siro spinning rotary separation type pressure rod spacer, in order to achieve the above purpose, its technical solution is:

A Siro-spinning rotary-separated pressure bar spacer, comprising a spacer and pressure bars symmetrically arranged at its left and right ends, the pressure bar is fixedly installed in the spacer through a bearing, and the bearing is located in the length direction of the spacer At the center position of the pressure rod, the pressure rod is in the shape of a smooth cylinder, and both ends of the pressure rod are symmetrically fixed with evenly arranged guide wheels.

The number of the guide wheels is three, the wheel width of the guide wheels is 1 mm, and the center distance between adjacent guide wheels is 1.3-2 mm.

Due to the adoption of the above technical scheme, compared with the prior art, the advantages of the siro spinning rotary separation type pressure rod spacer of the present invention are as follows:

The utility model changes the fixed connection between the pressure rod and the distance block in the past, and adds a bearing between the pressure rod and the distance block. The pressure rod is fixedly installed in the distance block through the bearing, and the bearing is located in the center of the length direction of the distance block. In terms of position, the pressure rod can be allowed to rotate freely in the distance block, and can effectively restrict the pressure rod from swinging left and right in the distance block, effectively preventing the instability caused by the left and right swing of the pressure rod from affecting the yarn quality , while strengthening the additional friction boundary in the front drafting zone longitudinally, while controlling the variable speed movement of the fibers in the strands in the front drafting zone, it is beneficial to reduce the blocking effect on the movement of fibers in the strands in the drafting zone, and improve the The yarn is even and dry.

The three guide wheels symmetrically arranged at both ends of the spacer can form two channels to control the movement of the two strands of Siro spinning respectively. The width of the guide wheel is 1mm, which can control the forced separation of the two strands of Siro spinning. It effectively solves the problem of two strands overlapping in the drafting area, and the distance between them reaches a small distance, ensuring that the two strands form a small twisting triangle area. The center distance between adjacent guide wheels is 1.3-2mm, ensuring The center distance of the guide wheel is adapted to the section width of the siro spinning sliver, especially the control of the edge fiber of the siro spinning sliver, which effectively reduces the loss of the edge fiber of the siro spinning sliver, reduces the hairiness of the yarn, and reduces the When high-count yarn is spun by technology, one of the two strands breaks.

The utility model has reasonable design, simple structure, very convenient installation and disassembly, and does not affect the operation of the car operator.
