[0023] Please see Figures 1-4This utility model provides an embodiment of a replaceable and freely adjustable yarn guide angle device for double-sided jacquard knitting, including a bracket 1. Two sets of fixed ear plates 2 are fixedly connected to the side wall of the bracket 1. A screw 3 is rotatably connected between the two sets of fixed ear plates 2. A first fixed plate 4 is threadedly connected to the surface of the screw 3. A fixed guide wheel 12 is rotatably connected to the side wall of the first fixed plate 4. A cross-shaped fixed plate 9 is fixedly connected to the side wall of the first fixed plate 4. A transverse guide wheel 10 and a longitudinal guide wheel 11 are rotatably connected to the side wall of the cross-shaped fixed plate 9. A second fixed plate 13 is fixedly connected to the lower surface of the first fixed plate 4. A telescopic cylinder 14 is fixedly connected to the surface of the second fixed plate 13. A third fixed plate is fixedly connected to the movable end of the telescopic cylinder 14. A fixed plate 15 is fixedly connected to a sleeve rod 16. A groove 17 is formed on the inner sidewall of the sleeve rod 16. A second slider 18 is slidably connected to the inner sidewall of the groove 17. An insertion rod 19 is fixedly connected to the sidewall of the second slider 18. An adjusting guide wheel 20 is fixedly connected to the top of the insertion rod 19. The transverse guide wheel 10, longitudinal guide wheel 11, fixed guide wheel 12, and adjusting guide wheel 20 are located on the same horizontal line. When guiding the yarn, the yarn passes through the transverse guide wheel 10, longitudinal guide wheel 11, fixed guide wheel 12, and adjusting guide wheel 20 in sequence. A slide rail 5 is fixedly connected to the sidewall of the bracket 1. A first slider 6 is slidably connected to the surface of the slide rail 5, and the sidewall of the first slider 6 is fixedly connected to the sidewall of the first fixed plate 4. A reducer 7 and a drive motor 8 are fixedly connected to the side wall. The power output end of the drive motor 8 is fixedly connected to the input end of the reducer 7, and the output end of the reducer 7 is fixedly connected to the shaft end of the lead screw 3. The drive motor 8 drives the lead screw 3 to rotate through the reducer 7, causing the threaded first fixed plate 4 to move along the slide rail 5. The first slider 6 assists in stabilizing the sliding trajectory. During this process, the fixed guide wheel 12, adjusting guide wheel 20, transverse guide wheel 10, and longitudinal guide wheel 11 fixed to the first fixed plate 4 are synchronously displaced, changing the guide reference of the yarn in the horizontal direction. The telescopic cylinder 14 drives the third fixed plate 15 to move up and down, driving the sleeve rod 16 and adjusting guide wheel 20 to rise and fall synchronously. The yarn passes through the transverse guide wheel 5 in sequence. The system includes guide roller 10, longitudinal guide roller 11, fixed guide roller 12, and adjusting guide roller 20. The height change of the adjusting guide roller 20 directly alters the angle between the yarn and the horizontal plane, enabling free adjustment of the yarn guiding angle. The combination of lateral displacement driven by the lead screw 3 and longitudinal lifting driven by the cylinder achieves multi-dimensional adjustment of the yarn guiding angle, adapting to the guiding needs of different patterns and yarns in double-sided jacquard knitting processes, thus improving the equipment's versatility. The cooperation between the slide rail 5 and the slider ensures smooth lateral movement. The coordinated guidance of the cross plate 9 and multiple sets of guide rollers reduces yarn friction loss and extends the equipment's service life. The guide roller assembly adopts a modular structure, facilitating quick replacement after wear, reducing maintenance costs, and ensuring production continuity.
[0024] In this embodiment, a limiting block 21 is slidably connected to the inner wall of the slide groove 17. A movable rod 22 is fixedly connected to the side wall of the limiting block 21. A tension spring 23 is fixedly connected to the top of the movable rod 22. The top of the tension spring 23 is fixedly connected to the bottom of the insertion rod 19. A threaded rod 24 is threadedly connected to the inner wall of the movable rod 22. A first bevel gear 25 is fixedly connected to the bottom of the threaded rod. A second bevel gear 26 is rotatably connected to the inner wall of the sleeve rod 16. The second bevel gear 26 meshes with the first bevel gear 25. A scale ring 27 is provided on the outer wall of the sleeve rod 16. A knob 28 is rotatably connected to the surface of the scale ring 27. One end of the knob 28... The tension spring 23 inside the sleeve rod 16 is fixedly connected to the shaft end of the second bevel gear 26. The tension spring 23 inside the sleeve rod 16 is connected to the insertion rod 19 through the movable rod 22 and the limiting block 21. The adjustment guide wheel 20 at the top of the insertion rod 19 can buffer the yarn tension fluctuation. When the knob 28 is turned, the second bevel gear 26 drives the first bevel gear 25 to rotate, so that the threaded rod 24 rotates in the movable rod 22. The rotation of the threaded rod 24 changes the rotational motion to linear motion, causing the movable rod 22 to rise and fall. The rise and fall of the movable rod 22 compresses the tension spring 23. By changing the deformation of the tension spring 23, different adaptive tension adjustment can be achieved. That is, by changing the preload of the tension spring 23, the yarn tension can be precisely controlled. The cooperation between the knob 28 and the scale ring 27 realizes the visual adjustment of tension. The automatic drive of the motor and cylinder reduces manual intervention, adapts to the needs of mass production, and improves work efficiency. The combination of the adaptive buffering of the tension spring 23 and the preload adjustment of the threaded rod 24 can stabilize the yarn tension, reduce knitting defects (such as broken yarn and missed needles) caused by tension fluctuations, and improve the quality of the fabric.
[0025] The drive motor 8 drives the lead screw 3 to rotate via the reducer 7, causing the threaded first fixed plate 4 to move along the slide rail 5. The first slider 6 assists in stabilizing the sliding trajectory. During this process, the fixed guide wheel 12, adjusting guide wheel 20, transverse guide wheel 10, and longitudinal guide wheel 11 fixed to the first fixed plate 4 move synchronously, changing the guide reference of the yarn in the horizontal direction. The telescopic cylinder 14 drives the third fixed plate 15 to move up and down, causing the sleeve rod 16 and adjusting guide wheel 20 to rise and fall synchronously. The yarn passes through the transverse guide wheel 10, longitudinal guide wheel 11, fixed guide wheel 12, and adjusting guide wheel 20 in sequence. The height change of the adjusting guide wheel 20 directly changes the yarn. The angle between the guide rod and the horizontal plane allows for free adjustment of the yarn guide angle. The tension spring 23 inside the sleeve rod 16 is connected to the insertion rod 19 via the movable rod 22 and the limiting block 21. The adjusting guide wheel 20 at the top of the insertion rod 19 can buffer yarn tension fluctuations. When the knob 28 is turned, the second bevel gear 26 drives the first bevel gear 25 to rotate, causing the threaded rod 24 to rotate within the movable rod 22. The rotation of the threaded rod 24 changes the rotational motion to linear motion, causing the movable rod 22 to rise and fall. The rise and fall of the movable rod 22 compresses the tension spring 23. By changing the deformation of the tension spring 23, different adaptive tension adjustments can be achieved, that is, the yarn tension can be precisely controlled by changing the preload of the tension spring 23.
[0026] The combination of lateral displacement driven by lead screw 3 and longitudinal lifting driven by cylinder enables multi-dimensional adjustment of the yarn guide angle, adapting to the guiding needs of different patterns and yarns in double-sided jacquard knitting, thus improving the equipment's versatility. The cooperation between slide rail 5 and slider ensures smooth lateral movement. The coordinated guidance of cross plate 9 and multiple sets of guide wheels reduces yarn friction loss and extends the equipment's service life. The guide wheel assembly adopts a modular structure, facilitating quick replacement after wear, reducing maintenance costs, and ensuring production continuity. The cooperation between knob 28 and scale ring 27 enables visual tension adjustment. The automated drive of motor and cylinder reduces manual intervention, adapting to batch production needs and improving work efficiency. Combined with the adaptive buffer of tension spring 23 and the preload adjustment of threaded rod 24, yarn tension can be stabilized, reducing knitting defects (such as yarn breakage and missed needles) caused by tension fluctuations, and improving fabric quality.
