Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a yarn twisting machine for preventing yarn tangling during emergency stops. It includes a housing 1, with multiple sizing shafts 2 rotatably connected to the inner wall of the housing 1. These shafts are positioned at different heights within the housing 1. A feed roller 3 is rotatably connected to the inner wall of the housing 1. The feed roller 3's main function is to support and guide the yarn through the rolling area. A pressure shaft 4 is located at the top of the feed roller 3, directly above it. The yarn passes through the gap between the pressure shaft 4 and the feed roller 3. A pressing mechanism is provided on both the front and rear sides of the pressure shaft 4. A stepper motor 5 is fixedly connected to the front of the housing 1. The stepper motor 5 can precisely control the rotation angle of its output shaft, improving control accuracy. A take-up roller 6 is fixedly connected to the rear side of the stepper motor 5's output shaft. The end of the take-up roller 6 away from the stepper motor 5 is rotatably mounted on the inner wall of the housing 1. A tensioning mechanism is provided inside the housing 1.

[0033] Reference Figure 1 - Figure 3 The tensioning mechanism includes a pressure rod 7, which is slidably mounted on the inner wall of the outer casing 1. The pressure rod 7 slides up and down. A spring 9 is fixedly connected to the bottom of the pressure rod 7. The spring 9 is initially set to a compressed state. A moving block 8 is fixedly connected to the bottom of the spring 9. The spring 9 applies a downward elastic force to the moving block 8. The moving block 8 slides on the inner wall of the outer casing 1. The moving block 8 slides up and down. A connecting rod 10 is hinged to the surface of the moving block 8. A connecting rod 2 11 is hinged to the end of the connecting rod 10 away from the moving block 8. Both the connecting rod 10 and the connecting rod 2 11 are set in an inclined state. The end of the connecting rod 2 11 away from the connecting rod 10 is hinged to the inner wall of the outer casing 1. The connecting rod 10 and the connecting rod 2 11 form a V-shape. The lengths of the connecting rod 10 and the connecting rod 2 11 are equal. A tension roller 12 is rotatably connected to the middle of the connecting rod 10. A control mechanism is provided on the front side of the pressure rod 7.

[0034] Reference Figure 3 , Figure 5The pressing mechanism includes a slider 20, which is slidably mounted on the inner wall of the housing 1. The slider 20 slides up and down. There are two sets of sliders 20. The side of the two sets of sliders 20 that are close to each other is rotatably connected to the front and rear sides of the pressure shaft 4. The pressing mechanism also includes a screw 17 that is set vertically. The screw 17 is threaded onto the inner wall of the housing 1. The bottom of the screw 17 is rotatably connected to a pressure block 18, which is slidably mounted on the inner wall of the housing 1. The pressure block 18 slides up and down. The pressing mechanism also includes a spring 19, which is initially set to a compressed state. The top of the spring 19 is fixedly connected to the bottom of the pressure block 18, and the bottom of the spring 19 is fixedly connected to the top of the slider 20. By setting the spring 19, the pressure block 18 and the slider 20 tend to move away from each other.

[0035] Reference Figure 1 , Figure 4 The control mechanism includes a control rod 13, which is slidably mounted on the inner wall of the pressure rod 7. The control rod 13 slides left and right. A handle is provided on the right side of the control rod 13 for easy operation. The control mechanism also includes a second spring 14, which is sleeved on the outside of 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. The second spring 14 applies a leftward elastic force to the control rod 13. The control mechanism also includes a fixing block 15, which is fixedly mounted on the front of the outer casing 1. The surface of the fixing block 15 has multiple circular holes 16 that cooperate with the control rod 13. These holes are arranged in a straight line at equal intervals on the surface of the fixing block 15. By inserting the control rod 13 into the circular holes 16 at different positions, the height of the pressure rod 7 can be changed.

[0036] Working principle: During use, the stepper motor 5 drives the take-up roller 6 to rotate, which evenly organizes the yarn on the multi-strand sizing shaft 2 into a single yarn and winds it onto the surface of the take-up roller 6. By rotating the screw 17, the screw 17 rotates and drives the pressure block 18 to move up and down through the action of the screw thread. The displacement of the pressure block 18 causes the length of the spring 3 19 to be stretched or compressed, thereby changing the downward pressure applied by the spring 3 19 to the slider 20. This allows control of the downward pressure of the pressure shaft 4 on the yarn. As the yarn moves to the right, it is squeezed by the pressure shaft 4 and the feed roller shaft 3 in the roller pressing area, thereby achieving roller pressing, improving the quality of multi-strand yarn integration, and having good control precision.

[0037] By pulling the control lever 13 to the right, the control lever 13 overcomes the elastic force of the second spring 14 and moves to the right, thereby disengaging the control lever 13 from the inside of the round hole 16. Then, the pressure lever 7 can be moved up and down. The displacement of the pressure lever 7 will squeeze the first spring 9, and the length of the first spring 9 will be compressed or stretched, thereby increasing or decreasing the elastic force applied by the first spring 9 to the moving block 8. The force of the tension roller 12 pressing down on the yarn is adjusted through the transmission of the first link 10 and the second link 11, so that the yarn always remains taut during the winding process. The tension of the yarn is adjusted by moving the pressure lever 7 up and down. By controlling the tension of the yarn, it is ensured that the yarn maintains a stable tension state during the winding process, avoiding slack and kinking.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
