Description

A pressurized separation type pressure rod distance block

technical field

The invention relates to a pressure-separated pressure bar spacer, specifically, a device for bundled strands is installed on existing spinning equipment, and belongs to the technical field of textile processing.

technical background

Spinning residual torque has always been a serious problem in knitting production. Single yarn torque is generated by twisting. Reducing the twist of single yarn can reduce the residual torque of yarn. However, in traditional ring spinning, reducing the twist of single yarn will lead to a decrease in yarn strength and affect spinning efficiency. In the spun yarn production process, the imperfection of the additional friction force circle will also affect the evenness of the yarn.

A production method and device for low-torque yarn, publication number CN101967706A, published on February 9, 2011, discloses a production method and device for low-torque yarn, which are used for the production of low-torque yarn. It mainly adopts a newly invented yarn false twisting device, which is installed above the spinning spindle. The yarn false-twisting device twists the sliver of the produced yarn after being drafted by the front roller and the front top roller according to the set number of twists and the twist in the opposite twist direction to the spinning spindle. Two types of twists are generated between the thread false twist device and the spinning spindle traveler: one is that the number of twists formed by the yarn false twist device is equal to the number of twists set above, and the twist direction is the same as that produced by the spinning spindle The twist; the other is the twist produced by the spinning spindle traveler. The three kinds of twists are superimposed, and the twist formed by the spinning spindle traveler is finally formed inside the yarn, and wound on the bobbin of the spinning spindle to complete the whole process of low-torque yarn production. In the spinning process, the fibers in the strands in the twisting triangle area will be split, which will affect the fiber distribution in the spinning triangle area, thereby changing the shape and arrangement of the fibers in the single yarn, resulting in residual fibers in the yarn. The torques are balanced against each other, but the spinning device is very complicated in this spinning process.

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 spacer and the pressure bar are fixedly connected together in a spacer of the upper pin pressure bar of the spinning frame, and the beard strips are adjusted during drafting.

The advancement of the yarn has a blocking effect, which affects the running of the fibers in the sliver, thereby affecting the evenness of the yarn.

Contents of the invention

In view of the above existing problems, the object of the present invention is to provide a pressurized separation type pressure rod spacer, in order to achieve the above purpose, its technical solution is: a pressurized separation type pressure rod distance block, the pressure The pressure-separated pressure bar spacer is composed of a spacer and a pressure bar movable in the spacer. The two ends of the pressure bar are symmetrically located on both sides of the spacer. The outer surface of the pressure bar is evenly distributed straight teeth. The range of the straight-toothed area is as wide as the width of the front top roller. A positioning groove is arranged at the center of the length of the pressure rod. The positioning pin is fixed on the distance block, and the head end of the positioning pin is placed in the positioning groove.

Due to the adoption of the above technical scheme, compared with the prior art, a pressurized separation type pressure bar spacer of the present invention has the advantages of:

1. The pressure rod is installed on the distance block, which strengthens the additional friction force in the front drafting area longitudinally, controls the variable speed movement of the fibers in the front drafting area, and is beneficial to reduce the impact on the whiskers in the drafting area. It can effectively prevent the fibers from being cut by the straight teeth when they are separated by the straight teeth.

2. The outer surface of the pressure rod is in the shape of evenly distributed straight teeth, which overcomes the common situation that the parallel separation of fibers is not high when the pressure rod is a smooth cylindrical shape. The evenly distributed straight teeth forcefully separate the whiskers into fine cotton The separation parallelism between the bundles and fibers is greatly improved, thereby changing the shape and arrangement of the fibers in the single yarn, and balancing the residual torque of the fibers in the yarn.

3. The range of the straight-toothed area is as wide as the width of the front top roller, which can effectively effect the whiskers on the entire width of the top roller.

4 The positioning pin is fixed on the distance block, and the head of the positioning pin is placed in the positioning groove, which allows the pressure rod to rotate freely in the distance block, but can effectively limit the left and right swing of the pressure rod in the distance block, effectively preventing The influence on the yarn quality caused by the unstable phenomenon caused by the left and right swing of the pressure bar.

The invention has reasonable design, very convenient installation and disassembly, and does not affect the operation of the car operator.

detailed description

Below in conjunction with accompanying drawing, the present invention is described in further detail, see accompanying drawing.

A pressurized and separated pressure bar spacer, the pressurized and separated pressure bar spacer is composed of a spacer 1 and a pressure bar 2, the spacer 1 has a through hole, and the pressure bar 2 is an integral root, movable set in the through hole of the distance block 1, the two ends of the pressure rod 2 are symmetrically located on both sides of the distance block 1, and are arranged symmetrically, the outer surface of the pressure rod 2 is in the shape of straight teeth evenly distributed. The fibers are longitudinally pressed by the pressure rod 2 and are separated and guided at the same time. The strands are subjected to longitudinal pressure in the front drafting area, and are subjected to the enhanced additional friction force during drafting, so that the fiber speed of the strands is drawn. Moving forward improves the evenness of the strands. The fibers in the sliver are separated and guided by the straight grain part, and the fibers are forcibly separated into fine cotton bundles. The separation parallelism between the fibers is improved, which affects the distribution of the fibers in the twisting triangle area, thereby changing the fiber distribution in the single yarn. The shape and arrangement distribution make the residual torque of the fibers in the yarn balance each other, and improve the yarn hairiness and yarn strength. The pressure rod 2 movable set in the through hole of the distance block 1 is beneficial to reduce the obstruction to the running of the fibers in the strands in the drafting area, and can effectively prevent the fibers from being cut by the straight teeth when they are separated by the straight teeth. The straight-toothed area is as wide as the width of the front top roller, which can effectively act on the whiskers of the entire top roller width. The center of the length of the pressure rod 2 is provided with a positioning groove 3, and the positioning pin 4 is fixed on the spacer 1. The positioning pin 4 The head end is placed in the positioning groove 3, which allows the pressure rod to rotate freely in the distance block, but can effectively limit the left and right swing of the pressure rod in the distance block, effectively preventing the influence of the left and right swing of the pressure rod on the yarn quality .
