[0018] Please see Figure 1-5 This utility model provides a technical solution: a yarn guiding device for a polyester yarn texturing machine, including a base 1, an installation bracket 2 fixedly connected to the upper end of the base 1, and an adjustment component. The adjustment component is set on the installation bracket 2 and includes a first connecting shaft 3, which is fixedly connected inside the installation bracket 2. A fixed plate 4 is fixedly connected to the front end of the first connecting shaft 3. A groove 15 is opened on the surface of the fixed plate 4. A threaded rod 16 is rotatably connected inside the groove 15. A slider 17 is threadedly sleeved on the surface of the threaded rod 16. The slider 17 is slidably connected to the groove 15. A third rotating shaft 19 is rotatably connected to the front end of the slider 17. A second yarn guiding wheel 20 is fixedly connected to the surface of the third rotating shaft 19. A second gear 18 is fixedly connected to the surface of the threaded rod 16. A toothed ring 13 is rotatably connected to the front side of the installation bracket 2. The teeth of the toothed ring 13 are set on its front end face. A second drive motor 14 is fixedly connected to the side surface of the fixed plate 4.

[0019] The number of slide groove 15, threaded rod 16, slider 17, second gear 18, third rotating shaft 19 and second guide wheel 20 are all symmetrically arranged on the fixed disk 4 in four sets, and the four second gears 18 are all engaged with the gear ring 13.

[0020] The output end of the second drive motor 14 is fixedly connected to the corresponding threaded rod 16.

[0021] The mounting bracket 2 is internally rotatably connected to a first rotating shaft 6. A connecting frame 8 is fixedly connected to the surface of the first rotating shaft 6. An arc-shaped groove 9 is provided on the surface of the mounting bracket 2. An arc-shaped block 10 is slidably connected inside the arc-shaped groove 9. A second rotating shaft 11 is fixedly connected inside the connecting frame 8. The second rotating shaft 11 is rotatably connected to the arc-shaped block 10. A first guide wheel 12 is rotatably connected to the front side of the second rotating shaft 11.

[0022] The first rotating shaft 6, the first gear 7, the connecting frame 8, the arc groove 9, the arc block 10, the second rotating shaft 11, and the first guide wheel 12 are each arranged in two sets symmetrically on the mounting bracket 2.

[0023] The rear end of the mounting bracket 2 is fixedly connected to a first drive motor 5. The output end of the first drive motor 5 is fixedly connected to the corresponding first rotating shaft 6. The surfaces of the two first rotating shafts 6 are fixedly connected to a first gear 7, and the two first gears 7 mesh with each other.

[0024] When using the device, the first drive motor 5 is fixed to the rear end of the mounting bracket 2, and its output shaft is connected to the first rotating shaft 6; the surfaces of the two first rotating shafts 6 are respectively fixed with first gears 7, and the two gears mesh with each other to achieve synchronous rotation in opposite directions.

[0025] When the first rotating shaft 6 rotates, it drives the connecting frame 8 to rotate around the axis of the first rotating shaft 6; the connecting frame 8 is rotatably connected to the arc block 10 through the second rotating shaft 11, and the arc block 10 slides along the arc groove 9 on the surface of the mounting bracket 2, thereby changing the horizontal distance of the first guide wheel 12.

[0026] By adjusting the horizontal distance between the two sets of first guide rollers 12, different widths of polyester filament bundles can be accommodated, avoiding yarn compression or loosening caused by a fixed distance.

[0027] The second drive motor 14 is fixed to the side surface of the fixed disk 4, and its output shaft is connected to the threaded rod 16; the second gear 18 is sleeved on the surface of the threaded rod 16 and meshes with the gear ring 13 on the front side of the mounting bracket 2.

[0028] The second drive motor 14 drives the threaded rod 16 to rotate. At the same time, through the meshing of the second gear 18 and the gear ring 13, the four sets of threaded rods 16 rotate synchronously. The gear ring 13 is a common gear, and all four second gears 18 mesh with it. When the threaded rod 16 rotates, it drives the slider 17 to slide radially in the slide groove 15 through the threaded transmission, and then adjusts the radial position of the second guide wheel 20 through the third rotating shaft 19.

[0029] Four sets of second guide rollers 20 are symmetrically distributed on the fixed plate 4. By moving synchronously radially, the spacing of the corresponding second guide rollers 20 can be precisely adjusted to adapt to polyester yarns of different thicknesses and reduce frictional damage between the yarn and the guide rollers.

[0030] The first guide wheel 12 and the second guide wheel 20 are both at the default spacing. The polyester yarn passes between the two sets of guide wheels and is pulled by the texturing machine traction wheel.

[0031] If the spacing between the guide wheels needs to be adjusted, the first drive motor 5 is started first. Through the meshing transmission of the first gear 7, the horizontal spacing between the two sets of first guide wheels 12 is adjusted synchronously to form a preliminary channel that adapts to the width of the filament bundle.

[0032] Then, the second drive motor 14 is started, and through the linkage between the gear ring 13 and the second gear 18, the four sets of second guide wheels 20 are driven to move radially in sync, reducing or expanding the guide hole diameter, closely fitting the outer diameter of the yarn, and achieving precise guidance.

[0033] If deviation occurs during the movement of the polyester filament, the guide roller corrects it through the following mechanism: The first guide wheel 12 can swing slightly by rotating the connecting frame 8 and sliding the arc block 10 to counteract the lateral deviation of the wire bundle; the second guide wheel 20 can finely adjust its radial position by sliding the slider 17 in the groove 15 to reduce wire wear caused by tension fluctuations. By combining horizontal spacing and radial adjustment, it breaks through the limitations of traditional single-dimensional yarn guide devices and is compatible with the production of polyester yarns of various diameters.

[0034] The meshing of the first gear 7 ensures that the two sets of first guide wheels 12 move synchronously in opposite directions, avoiding uneven loading; the meshing of the gear ring 13 with the four sets of second gears 18 enables the second guide wheels 20 to move synchronously at equal distances, ensuring the symmetry of the second guide wheels 20 and preventing uneven force on the yarn.

[0035] By precisely adjusting the distance between the first guide roller 12 and the second guide roller 20, the yarn passes through in a state of no compression and low friction, which significantly reduces the breakage rate and fabric defect rate, and improves the production efficiency and product quality of the texturing machine.

[0036] Furthermore, through the meshing transmission of the first drive motor 5 and the first gear 7, the horizontal distance between the two sets of first guide wheels 12 can be adjusted synchronously to form a preliminary channel suitable for polyester filament bundles of different widths. At the same time, the second drive motor 14 drives the gear ring 13 to work in conjunction with the four sets of second gears 18, so that the four sets of second guide wheels 20 move radially synchronously and precisely adjust the guide hole diameter. This dual adjustment mechanism of horizontal distance and radial hole diameter can be compatible with the production of polyester filaments of various diameters, avoid yarn compression or loosening caused by fixed distance, and reduce frictional damage between yarn and guide wheels.

[0037] Structural Description: Base 1: Serves as the basic support structure of the device, fixing the entire wire guide device and ensuring its installation stability on the texturing machine; Mounting bracket 2: connects the base and the adjustment component, provides a mounting carrier for the first guide wire wheel group, the second guide wire wheel group and the drive motor, and guides the movement trajectory of the adjustment component through the internal structure (such as the arc groove 9); First drive motor 5: As a power source, it drives the first rotating shaft 6 to rotate and realizes the horizontal distance adjustment of the two sets of first guide wheels 12 through gear transmission; First rotating shaft 6: transmits power from the first drive motor 5, drives the connecting frame 8 to rotate around its axis, and thereby adjusts the position of the first guide wheel 12; First gear 7: Two first gears 7 mesh with each other to ensure that the two sets of first guide wheels 12 rotate synchronously in opposite directions, avoid uneven load during adjustment, and ensure the symmetry of the lateral constraint of the wire bundle; Connecting frame 8: One end is fixedly connected to the first rotating shaft 6, and the other end is connected to the arc block 10 through the second rotating shaft 11, which converts the rotational motion of the first rotating shaft 6 into the horizontal swing of the first guide wheel 12; Arc groove 9 and arc block 10: Arc block 10 slides along arc groove 9, restricting the movement trajectory of connecting frame 8, so that the first guide wheel 12 can only adjust the spacing in the horizontal direction, while allowing it to swing slightly when the wire bundle deviates for dynamic correction. The second rotating shaft 11 and the first guide wheel 12: The second rotating shaft 11 supports the first guide wheel 12 and allows it to rotate. The first guide wheel 12 directly contacts the yarn bundle and adapts to different widths of polyester yarn bundles by adjusting the horizontal spacing to prevent compression or loosening. The second drive motor 14 serves as a power source, driving the threaded rod 16 to rotate and achieving synchronous adjustment of the radial positions of the four sets of second guide wheels 20 through gear transmission. First connecting shaft 3 and fixed plate 4: First connecting shaft 3 is fixed inside the mounting bracket 2 and supports fixed plate 4; fixed plate 4 serves as the mounting base for the second guide wheel assembly, and its surface groove 15 provides a sliding track for slider 17; Threaded rod 16 and slider 17: When the threaded rod 16 rotates, it drives the slider 17 to slide radially in the groove 15 through threaded transmission, thereby adjusting the radial position of the second guide wheel 20; the cooperation between the slider 17 and the groove 15 ensures the smoothness of the movement and the guiding accuracy. Second gear 18 and gear ring 13: All four second gears 18 mesh with the gear ring 13 to form a common gear transmission system, ensuring that the four sets of threaded rods 16 rotate synchronously, so that the second guide wheel 20 moves synchronously at equal distances, ensuring the symmetry of the guide hole diameter; The third rotating shaft 19 and the second guide wheel 20: The third rotating shaft 19 supports the second guide wheel 20 and allows it to rotate. The second guide wheel 20 adjusts the guide hole diameter by moving radially, closely fitting yarns of different thicknesses and reducing friction damage.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
