Description

TECHNICAL FIELD

[0001] The present application belongs to the field of textiles, and particularly relates to a mechanism for compact spinning of siro spinning and a siro compact spinning process thereof. BACKGROUND

[0002] Siro spinning is to feed two rovings with a certain spacing on a spinning frame, and after drafting, the two single yarn slivers are output from the front roller to the output roller, and a small amount of twist is brought to the single yarn sliver due to the transfer of twist, and after splicing, it is further twisted into a yarn similar to a ply, and is wound on a bobbin. Siro spinning has the advantages of less hairiness, high strength and good wear resistance, and achieves the effect of single yarn weaving of wool yarn to realize the lightness of wool fabric. With people's increasing demand for fabric style, siro compact spinning is increasingly favored by people, but in the spinning process, the two single yarn slivers of siro spinning are spliced and combined into one body, which is difficult to reflect the unique performance of siro spinning in this case.

[0003] Therefore, in order to ensure the excellent performance of siro spinning, two splicing grooves are usually arranged on the special-shaped tube, and a certain splicing effect is generated on the single yarn sliver by the negative pressure airflow in the Z-axis direction. The airflow movement state is from the area outside the splicing groove edge to the area inside the splicing groove edge, and the airflow volume of the area outside the splicing groove is less than that of the area inside the splicing groove. At the same time, since the single yarn sliver moves with the mesh ring to the output roller during splicing, the splicing of the single yarn sliver is uneven, the splicing effect of the single yarn sliver close to the splicing groove position is good, and the splicing effect of the single yarn sliver far away from the splicing groove position is poor. Therefore, it is also impossible to obtain relatively stable and good siro spinning yarn. SUMMARY

[0004] The purpose of the present application is to overcome the above shortcomings, and to provide a mechanism for compact spinning of siro spinning and a siro compact spinning process thereof, so as to obtain relatively stable and good siro spinning yarn.

[0005] The purpose of the present application is achieved by the following technical scheme: a mechanism for compact spinning of siro spinning, comprising a front roller, an output roller, a tension roller, a mesh ring and a special-shaped tube, the mesh ring is sleeved on the output roller, the tension roller and the special-shaped tube, and the mesh ring rotates around the output roller, the tension roller and the special-shaped tube under the rolling driving of the output roller;

[0006] The surface of the special-shaped tube has a left splicing groove and a right splicing groove, the left splicing groove and the right splicing groove are oppositely or oppositely inclined to form a V-shaped structure, and a negative pressure airflow for splicing the two single yarn slivers on the mesh ring is generated in the special-shaped tube;

[0007] The two side end portions of the special-shaped tube protrude from the two side end portions of the mesh ring and have baffles, the baffles have positive pressure air flows blowing towards the single yarn sliver, a flow dividing block is located directly above the left and right collecting grooves, the flow dividing block is located directly above the mesh ring, the outer wall of the flow dividing block is sequentially arranged corresponding to the inner walls of the left and right collecting grooves, and the flow dividing block has positive pressure air flows blowing towards the single yarn sliver.

[0008] Further improvement of the present application is that the distance between the left and right collecting grooves gradually decreases from the front roller to the output roller.

[0009] Further improvement of the present application is that the distance between the left and right collecting grooves gradually decreases from the front roller to the output roller.

[0010] A Siro compact spinning process of a Siro compact spinning mechanism, two single yarn slivers are placed above the mesh ring after being drawn and move with the mesh ring from the front roller to the output roller, under the action of negative pressure air flows of the left and right collecting grooves, the two single yarn slivers generate friction force between each other and are collected on the corresponding left and right collecting grooves, to achieve the effect of preliminary collection, meanwhile, the baffles and the flow dividing block blow positive pressure air flows to the corresponding single yarn sliver, the positive pressure air flows drive the single yarn sliver in the outer side area of the left and right collecting grooves to move to the area of the left or right collecting groove, to achieve the effect of further collection, so that the two single yarn slivers after being collected are further twisted to form yarns and are wound on the bobbin, to become compact Siro yarns with ply structure.

[0011] Further improvement of the present application is that the parameter conditions of the Siro compact spinning mechanism are as follows: the spindle speed is 12000 rpm, the roller gauge is 22x40 mm, the nip gauge block is 2.5 mm, and the twist factor is 340.

[0012] Compared with the prior art, the present application has the following advantages:

[0013] The negative pressure airflow generated by the collecting groove has a certain fixing effect on the single yarn sliver, ensures that the single yarn sliver is attached to the surface of the mesh ring and moves with the mesh ring, and has a good collecting effect on the single yarn sliver, so that the single yarn sliver dispersed on both sides of the collecting groove is collected to the middle. The airflow moves from top to bottom in the collecting groove, and a certain pressure effect is generated on the single yarn sliver. With the pressure effect, friction is generated between the single yarn sliver and the mesh ring and between the single yarn slivers. The single yarn sliver subjected to the airflow will reach a relatively stable state. At the same time, the single yarn sliver moves from the outside to the inside of the collecting groove under the action of the airflow, and the collecting effect is achieved. Secondly, the positive pressure airflow blown by the baffle and the flow divider to the corresponding single yarn sliver drives the single yarn sliver in the outer side area of the left collecting groove and the right collecting groove to move to the area of the left collecting groove or the right collecting groove, so that the effect of further collecting is achieved, and relatively stable and well-collected siro spinning yarn can be obtained.
