By setting the first spring 9, a downward elastic force is applied to the moving block 8. The moving block 8 is slidably installed on the inner wall of the housing 1, the sliding direction of the moving block 8 is up and down. One end of a connecting rod 10 is hinged to the surface of the moving block 8. One end of the connecting rod 10 away from the moving block 8 is hinged to a connecting rod 11. Both the connecting rod 10 and the connecting rod 11 are arranged in an inclined state. One end of the connecting rod 11 away from the connecting rod 10 is hinged to the inner wall of the housing 1. The connecting rod 10 and the connecting rod 11 form a V shape, and the lengths of the connecting rod 10 and the connecting rod 11 are equal. A tension roller 12 is rotatably connected to the middle of the connecting rod 10. A control mechanism is arranged on the front side of the pressing rod 7.

[0021] Refer to Figure 3 , Figure 5 , the pressing mechanism includes sliders 20. The sliders 20 are slidably installed on the inner wall of the housing 1, the sliding direction of the sliders 20 is up and down, the number of the sliders 20 is set to be two groups, and the mutually close sides of the two groups of sliders 20 are rotatably connected to the front and rear sides of the pressing shaft 4. The pressing mechanism further includes a vertically arranged screw rod 17, the screw rod 17 is threadedly installed on the inner wall of the housing 1, a pressing block 18 is rotatably connected to the bottom of the screw rod 17, the pressing block 18 is slidably installed on the inner wall of the housing 1, the sliding direction of the pressing block 18 is up and down.

[0022] Referring to Figure 1 、 Figure 4 The control mechanism includes a control rod 13. The control rod 13 passes through and is slidably installed on the inner wall of the pressure rod 7. The sliding direction of the control rod 13 is left - right sliding. A handle is provided on the right side of the control rod 13 to facilitate the staff to pull the control rod 13. The control mechanism further includes a second spring 14. The second spring 14 is sleeved outside the control rod 13. The control rod 13 is elastically connected to the inner wall of the pressure rod 7 through the second spring 14. By setting the second spring 14, an elastic force towards the left is applied to the control rod 13. The control mechanism further includes a fixed block 15. The fixed block 15 is fixedly installed on the front surface of the housing 1. A round hole 16 that cooperates with the control rod 13 is provided on the surface of the fixed block 15.

By inserting the control rod 13 into the round holes 16 at different positions, the height of the pressure rod 7 can be changed.

[0023] Working principle: When in use, the stepping motor 5 works to drive the winding roller 6 to rotate, evenly arranging the yarns on the multi - strand pulp shaft 2 into one strand of yarn and winding it on the surface of the winding roller 6. By rotating the screw rod 17, the screw rod 17 rotates and drives the pressure block 18 to move up and down through the action of thread conversion. The displacement of the pressure block 18 causes the length of the third spring 19 to be stretched or compressed, thereby changing the downward pressure exerted by the third spring 19 on the slider 20, and further controlling the downward pressure of the pressing shaft 4 on the yarn. As the yarn continuously moves to the right, it is squeezed by the pressing shaft 4 and the feeding roller shaft 3 in the rolling area, thus realizing the rolling process and improving the quality of multi - strand yarn integration, with better control accuracy.

[0024] By pulling the control rod 13 to the right, the control rod 13 overcomes the elastic force of the second spring 14 and moves to the right, so that the control rod 13 disengages from the inside of the round hole 16. Then the pressure rod 7 can be moved up and down. The displacement of the pressure rod 7 will squeeze the first spring 9 and cause the length of the first spring 9 to be compressed or stretched, thereby increasing or decreasing the elastic force exerted by the first spring 9 on the moving block 8, and adjusting the force of the tension roller 12 pressing down on the yarn through the transmission of the first connecting rod 10 and the second connecting rod 11, so that the yarn always remains in a tensioned state during the winding process, and the tension of the yarn is adjusted by moving the pressure rod 7 up and down. By controlling the tension of the yarn, it is ensured that the yarn maintains a stable tension state during the warping process, avoiding slackness and kinking.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
