Embodiment Construction

[0009] In traditional ring spinning, the bobbin (15) rotates through the rotation of the spindle, driving the traveler (13) to rotate along the raceway of the steel ring (14), thereby transferring the twist to the front roller (12) and the front rubber roller (11) ) at the beard of the holding part, and at the same time, the friction force between the traveler (13) and the steel ring (14) causes a speed difference, thereby winding the yarn (7) onto the bobbin (15).

[0010] Depend on figure 1 As shown, the eddy current yarn guide device is mainly composed of the eddy current yarn guide device (1) and the compressed airflow input interface (2), replacing the original yarn guide hook, and the eddy current yarn guide device is installed and fixed on the yarn guide by screws (10). on the board (9). The eddy current guide (1) has a cylindrical yarn guide channel (5) in the vertical direction, and the inner wall of the cylindrical yarn guide channel (5) is processed into a left-han...

Abstract

The invention relates to a novel method and device for processing vortex ring spun yarn. The technical transformation of a winding and twisting section which is configured at a drawing part in a spinning machine and used for finally sending yarn out of a downstream part of a roller in a paired manner can be directly applied to the technical transformation of the spinning machine. By adopting the method and the device for processing the vortex ring spun yarn to replace original guide wires, the twist fault effect of the original guide wires is weakened, vortex generated by compressed air is effectively utilized for changing twist transmission and yarn formation during the yarn formation process, the flow rate of compressed airflow can be changed in a range from 0-0.5MPa through an air pressure valve according to different yarn counts and process demands, thereby being conductive to the reduction of yarn-forming hair feather and increase of the strength of the yarn. Compared with other technologies, the device is simple and convenient to mount and high in performance-price ratio.

Description

technical field [0001] The present invention relates to the new technology field of ring spinning, in particular to a technical transformation of the winding and twisting part applied downstream of the drafting device of the ring spinning frame, which reduces yarn hairiness and increases yarn hairiness by compressing gas to generate vortex. Yarn processing method and device for yarn strength. Background technique [0002] Ring spinning technology is currently the most widely used spinning technology at home and abroad, but this technology increases the amount of hairiness due to the existence of twisting triangles. In recent years, many methods have been adopted to change the shape of the twisting triangle, such as compact spinning, cable spinning, dislocation spinning and other technologies, so as to reduce hairiness. [0003] The compact spinning technology mainly adds a fiber control area in front of the traditional drafting device, and uses the airflow to laterally cond...
