[0028] The principle of realizing four-fold twisting

[0029] The twisted yarn is led out from point A in the yarn storage and supply component, first enters point B of the spindle wing of the tension adjustment component, then enters the interior of the tension adjustment component. After being tension-controlled inside the tension adjustment component, it enters point D of the yarn guide opening of the upper twisting component downward from point C of the yarn outlet of the tension adjustment component, and enters the upper twisting component from point D and reaches point E at the junction of the upper twisting component and the lower twisting component.

[0030] It enters the lower twisting component at point E, exits from the yarn guiding point F of the lower twisting component after passing through the lower twisting component, and then enters the upper yarn guiding point G upward. The twisted yarn passes through the upper yarn guiding point and is wound and formed to form a twisted cheese, completing the entire twisting process.

[0031] The endless belt drives the spindle pulley, transmits the spindle shaft, and rotates the lower twisting component. Due to the rotation of the lower twisting component, point D is a twisting point, causing a twist in the CD section of the yarn and a twist in the DE section in the same direction as the CD section.

[0032] The lower transmission gear and then drives the upper transmission gear and the upper spindle rod through the transmission gear. Therefore, the transmission directions of the spindle shaft and the upper spindle rod are opposite.

[0033] It enters the lower twisting component at point E, exits from the yarn guiding point F of the lower twisting component after passing through the lower twisting component, and then enters the upper yarn guiding point G upward. The upper yarn guiding point G is fixed, and the yarn guiding point F is a twisting point of the spindle shaft. Since the transmission directions of the spindle shaft and the upper spindle rod are opposite, a twist in the same direction as the DE section is generated in the EF section, and a twist in the same direction as the EF section is generated in the FG section that turns back from the yarn guiding point F, for a total of four twists.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
