The other end of the main twisting transmission belt 9 is sleeved on the output shaft of the main twisting motor 10 and is driven by the main twisting motor 10.

[0026] A permanent magnetic main pulley 12 which can rotate horizontally is provided on the outer wall of the hollow main shaft 20 above the main twisting transmission belt 9 through a bearing sliding sleeve.

A permanent magnetic slave pulley 7 which can rotate horizontally is also provided on the outer wall of the hollow main shaft 20 above the main twisting disk 8 through a bearing sliding sleeve. The permanent magnetic main pulley 12 and the permanent magnetic slave pulley 7 are magnetically coupled in the air. The pulley 6 is arranged on the outside of the permanent magnetic slave pulley 7, and forms a planetary transmission with the permanent magnetic slave pulley 7 through a belt.

[0027] Specifically, a plurality of first spindles 3 and second spindles 4 are evenly arranged on the sub-twisting disk 5, and the first spindles 3 and the second spindles 4 are vertically arranged and evenly arranged with the hollow main shaft 20 as the axis. A pay-off assembly is provided at the top of the hollow main shaft 20. In this embodiment, the first spindles 3 and the second spindles 4 both adopt spindle components, which are more convenient for yarn release.

[0028] Specifically, the pay-off assembly matches the first spindle 3 and the second spindle 4, and the pay-off assembly includes a second lead ring 17, a guide wheel 18 and a cylindrical tension damper 2. The second lead ring 17 is arranged on the top of the hollow main shaft 20, and the guide wheels 18 are evenly mounted on the end of the hollow main shaft 20 and are evenly arranged in a radial shape. The cylindrical tension damper 2 is mounted above the guide wheel 18 through a bracket. In this embodiment, refer to the attached Figure 2 Only four first spindles 3 are drawn in the drawing. The staff can adjust the number of the first spindles 3 according to actual needs. Both symmetrical and asymmetrical settings are possible. The staff can decide whether to use the cylindrical tension damper 2 according to their own needs.

[0029] Specifically, the hollow main shaft 20 is a cylindrical component, and a through hole is opened on the lower end side surface of the hollow main shaft 20. A radial hole for discharging the yarn is also opened at the same position on the side wall of the main twisting disk 8. In this embodiment, the through hole and the radial hole are at the same position for releasing the yarn.

[0030] Specifically, the first spindle 3, the second spindle 4 and the sub-twisting disk 5 are all hollow components.

[0032] Working principle and use process of the utility model: During the use of the technical solution in the utility model, a wire passing ring 19 for guiding the yarn, a traction mechanism 14 for pulling the yarn, a wire arranging mechanism 15 for arranging the yarn, and a wire take-up drum 1 for winding the yarn are also provided at the end of the device; the traction mechanism 14 and the wire arranging mechanism 15 both adopt the existing technology currently on the market, so they are not described here in detail; during the operation of the device, the staff needs to first place the first spindle 3 and the second spindle 4 on the sub-twisting disk 5, and pass the yarn from the first lead ring 16 into the interior of the sub-twisting disk 5, and the yarn is discharged from the discharge hole. The yarn is then transported to the second lead ring 17 through the cylindrical tension damper 2 and the guide wheel 18, and is guided to the main twisting disk 8 through the hollow main shaft 20, and discharged from the radial hole of the main twisting disk 8, and passes through the wire passing ring 19, the traction mechanism 14, and the wire arranging mechanism 15 upward, and then the wire winding is completed by the rotation of the take-up drum 1;

[0033] The bearing seat 11 in the technical solution is fixedly connected to the frame of the twisting machine. The main twisting motor 10 drives the main twisting transmission belt 9 to rotate during the power-on operation, and then drives the hollow main shaft 20 to rotate synchronously. The main twisting disk 8 is driven to rotate during the rotation of the hollow main shaft 20. The main twisting disk 8 will throw the twisted yarn out of the radial hole at a high speed during the rotation process, and the twisting of the yarn is completed at this time;

[0034] The sub-twisting motor 13 drives the permanent magnet main pulley 12 to rotate during the power-on process. The permanent magnet main pulley 12 and the permanent magnet slave pulley 7 are magnetically coupled in the air. During the rotation of the permanent magnet slave pulley 7, the pulley 6 will be synchronously driven to rotate through the planetary structure, and then the sub-twisting disk 5 can be driven to rotate. During the rotation, the sub-twisting disk 5 throws the twisted wire out of the discharge hole to complete the yarn unwinding. During this process, the second lead ring 17, the guide wheel 18 and the cylindrical tension damper 2 rotate with the hollow main shaft 20 as the rotation axis at the same angular velocity. At this time, the first spindle 3 and the second spindle 4 will rotate synchronously with the unwinding assembly and remain relatively still. The air-magnetic coupling transmission technology is used to achieve the rotation speed non-interference between the main twisting disk 8 and the sub-twisting disk 5, thereby achieving the purpose of arbitrarily adjusting the main twist and sub-twist ratio.
