Description

Technical Field

[0001] This utility model relates to the field of wire guide technology, and in particular to a wire guide for a high-speed texturing machine. Background Technology

[0002] During the texturing process of yarn in a high-speed texturing machine, ensuring the stable and precise guidance of the yarn and preventing its slippage is crucial. In practical applications, the yarn guide of a high-speed texturing machine typically has the following key structures:

[0003] 1. Guiding structure: It adopts components such as high-precision guide wheels and guide hooks. The guide wheels, with their carefully designed precise surface curvature, fit closely with the wire and guide the wire to travel along a specific trajectory.

[0004] 2. Anti-jump structure: For example, adjustable limiting devices are installed on both sides of the guide wheel, which can adjust the limiting range of the wire according to the thickness of the wire and the running conditions to prevent the wire from jumping out from the side of the guide wheel;

[0005] 3. Cleaning and maintenance structure: Equipped with an automatic cleaning brush, which regularly cleans the surface of key components such as the guide roller to remove attached oil, fiber impurities, etc.

[0006] A texturing machine is a textile machine that can process untwisted yarns such as polyester and polypropylene into elastic yarns with medium and low elasticity through false twisting. Under the traction of the texturing machine's traction wheel, the yarn is wound in the core. During the process of the traction wheel pulling the yarn, the yarn often deviates. Therefore, a yarn guide device is usually installed on the texturing machine to correct the yarn in real time and prevent the yarn from deviating.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: Currently, the guide wire often deviates to the left or right during high-speed movement. When the deviation distance is too large, the untwisted wire will move out of the outside of the roller, resulting in wire skipping and poor stability. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a guide for a high-speed texturing machine, which solves the technical problem that current guides often deviate left and right during high-speed movement. When the deviation distance is too large, the untwisted yarn will move out of the outside of the roller, resulting in skipped threads and poor stability.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A guide for a high-speed texturing machine includes a mounting base, a lifting frame slidably mounted on the mounting base, ceramic bearings symmetrically fixedly mounted on the lifting frame, ceramic guide wheels fixedly mounted on the inner sidewalls of the ceramic bearings, and herringbone gears fixedly mounted on the output shafts of the ceramic guide wheels to prevent the ceramic guide wheels from deviating. The two herringbone gears mesh with each other, and a threaded rod for driving the lifting frame to slide up and down is rotatably mounted on the mounting base. The threaded rod is threadedly connected to the lifting frame.

[0011] Preferably, a knob is fixedly installed on the threaded rod.

[0012] Preferably, a sliding bracket is symmetrically slidably mounted on the mounting base.

[0013] Preferably, mounting blocks are symmetrically slidably mounted on the sliding frame.

[0014] Preferably, the sliding bracket has first bolts symmetrically threaded at both ends, and the first bolts and the sliding bracket can clamp the mounting base.

[0015] Preferably, a second bolt is threaded onto the side end of the mounting block, and the side end of the second bolt can abut against the sliding frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. During use, the two ceramic guide wheels are restricted by two meshing herringbone gears on their sides, causing them to rotate synchronously. This prevents the two ceramic guide wheels from rotating asynchronously due to jamming of one of them during the traction of the wire, which would result in uneven force on both ends of the wire and changes in tension. The ceramic bearings between the ceramic guide wheels and the lifting frame reduce friction during the rotation of the ceramic guide wheels and improve their rotational stability. At the same time, the two herringbone gears have equal helix angles and opposite directions of rotation. When the two herringbone gears mesh, they restrain each other, preventing axial force from the two herringbone gears and inhibiting the axial deflection of the two ceramic guide wheels. This effectively prevents the wire from jumping due to axial deviation.

[0018] 2. During installation, slide the sliding frame and mounting blocks according to the mounting hole positions to align the mounting blocks with the mounting holes. Once all four mounting blocks are aligned, tighten the first bolt to clamp the mounting base with the sliding frame, thus fixing the position of the sliding frame. Then tighten the second bolt, whose side end will abut against the side end of the sliding frame, thus fixing the mounting blocks. After the mounting base is installed, turn the knob to rotate the threaded rod. Since the threaded rod is threadedly connected to the lifting frame, it can drive the lifting frame to slide up and down, achieving the effect of easy adjustment according to installation requirements.

[0026] This application provides a guide for a high-speed texturing machine, effectively solving the technical problem of poor stability caused by frequent left-right deviation of current guides during high-speed movement. When the deviation is too large, the untwisted yarn may move outside the rollers, leading to skipped yarn. During use, the two ceramic guide wheels are restricted by two meshing herringbone gears on their sides, ensuring synchronous rotation. This prevents the two ceramic guide wheels from rotating asynchronously due to jamming of one wheel during yarn pulling, thus avoiding uneven force on both ends of the yarn and changes in tension. The ceramic bearing between the ceramic guide wheels and the lifting frame reduces friction during rotation, improving stability. Simultaneously, the two helical angles of the herringbone gears are equal but opposite in direction, ensuring stable rotation. When meshing, they will restrain each other, preventing the two herringbone gears from generating axial force and inhibiting the axial deflection of the two ceramic guide wheels. This effectively prevents the wire from skipping due to axial offset. During installation, slide the sliding frame and mounting blocks according to the mounting hole positions so that the mounting blocks are aligned with the mounting holes. After all four mounting blocks are aligned, tighten the first bolt to clamp the mounting base with the sliding frame, thus fixing the position of the sliding frame. Then tighten the second bolt, and the side end of the second bolt will abut against the side end of the sliding frame, thus fixing the mounting blocks. After the mounting base is installed, the knob can be turned to rotate the threaded rod. Since the threaded rod is threadedly connected to the lifting frame, it can drive the lifting frame to slide up and down, achieving the effect of easy adjustment according to installation requirements. Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem that the current yarn guide often deviates left and right during high-speed movement. When the deviation distance is too large, the untwisted yarn will move out of the outer side of the roller, resulting in skipped yarn and poor stability. The overall idea is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a guide for a high-speed texturing machine, including a mounting base 1, a lifting frame 2 slidably mounted on the mounting base 1, ceramic bearings 3 symmetrically fixedly mounted on the lifting frame 2, ceramic guide wheels 4 fixedly mounted on the inner side wall of the ceramic bearings 3, and a herringbone gear 5 fixedly mounted on the output shaft of the ceramic guide wheels 4 to prevent the ceramic guide wheels 4 from deviating.

[0029] Two herringbone gears 5 mesh with each other. A threaded rod 6 for driving the lifting frame 2 to slide up and down is rotatably mounted on the mounting base 1. The threaded rod 6 is threadedly connected to the lifting frame 2. A knob 7 is fixedly mounted on the threaded rod 6. A sliding frame 8 is symmetrically slidably mounted on the mounting base 1.

[0030] Mounting blocks 9 are symmetrically mounted on the sliding frame 8. First bolts 11 are symmetrically threaded at both ends of the sliding frame 8. The first bolts 11 and the sliding frame 8 can clamp the mounting base 1. Second bolts 12 are threaded on the side end of the mounting block 9. The side end of the second bolt 12 can abut against the sliding frame 8.

[0031] Mounting base 1: As the main structure of the high-speed texturing machine guide wire, it provides the mounting base for other components. During the installation process, it is clamped and fixed in position by the sliding frame 8 and the first bolt 11. At the same time, the lifting frame 2 can slide on it, and the threaded rod 6 is also rotatably mounted on it. It is the core load-bearing component of the entire guide wire.

[0032] Lifting frame 2: It is slidably mounted on the mounting base 1 and plays the role of connecting and transmitting motion. It is threadedly connected to the threaded rod 6 and can slide up and down when the threaded rod 6 rotates to meet different installation requirements. At the same time, it also provides a fixed installation position for the ceramic bearing 3, which indirectly affects the position of the ceramic guide wheel 4 and related components.

[0033] Ceramic bearing 3: Symmetrically fixedly installed on the lifting frame 2. The ceramic material has high hardness, which can reduce the deviation caused by wear during long-term use. It is located between the ceramic guide wheel 4 and the lifting frame 2. Its main function is to reduce the friction during the rotation of the ceramic guide wheel 4, improve the stability of the rotation of the ceramic guide wheel 4, and ensure that the ceramic guide wheel 4 can run smoothly during the wire guiding process, thereby stably pulling the wire.

[0034] Ceramic guide wheel 4: Fixed to the inner wall of ceramic bearing 3. The ceramic material has high hardness and a smooth surface, which can reduce the deviation caused by wear during long-term use and is easy to clean. Herringbone gear 5 is installed on its rotating shaft. The ceramic guide wheel 4 is responsible for directly pulling the wire during the wire guiding process. By cooperating with the herringbone gear 5, it rotates synchronously under the restriction of the herringbone gear 5, avoiding the two ceramic guide wheels 4 from rotating asynchronously due to jamming, preventing uneven force and tension changes at both ends of the wire, and ensuring stable operation of the wire.

[0035] Herringbone gear 5: Fixedly installed on the output shaft of ceramic guide wheel 4. The two herringbone gears 5 mesh with each other. Since their helix angles are equal and their rotation directions are opposite, they can restrain each other when meshing, avoiding the generation of axial force, thereby suppressing the axis deflection of the two ceramic guide wheels 4, effectively preventing the wire from jumping due to axial offset, and ensuring the stability of the wire position during the wire guiding process.

[0036] Threaded rod 6: Rotatably mounted on mounting base 1 and threadedly connected to lifting frame 2. By turning the knob 7, which is fixedly connected to threaded rod 6, threaded rod 6 is rotated, thereby driving lifting frame 2 to slide up and down, so that the position of the wire guide can be adjusted according to actual needs during installation.

[0037] Knob 7: Fixedly installed on the threaded rod 6 as an operating component. By turning the knob 7, the threaded rod 6 can be rotated, thereby driving the lifting frame 2 to slide up and down, making it convenient for operators to install and adjust the wire guide.

[0038] Sliding bracket 8: It is symmetrically slidably installed on the mounting base 1. During the installation process, the position of the sliding bracket 8 is adjusted by sliding the sliding bracket 8 so that the mounting block 9 is aligned with the mounting hole. Then, by tightening the first bolt 11, the sliding bracket 8 and the first bolt 11 clamp the mounting base 1 together to fix the position of the mounting base 1, and at the same time provide a sliding installation base for the mounting block 9.

[0039] Mounting block 9: It is symmetrically slidably mounted on the sliding frame 8. During installation, the mounting block 9 is aligned with the mounting hole position to provide precise calibration for the installation and positioning of the entire wire guide. After the position of the sliding frame 8 is fixed, the second bolt 12 is tightened so that the second bolt 12 abuts against the side end of the sliding frame 8, thereby fixing the position of the mounting block 9.

[0040] First bolt 11: Threaded installation at both ends of sliding frame 8. When the first bolt 11 is tightened, the first bolt 11 and sliding frame 8 cooperate to clamp the mounting base 1, thereby fixing the position of sliding frame 8 on mounting base 1 and ensuring the overall stability of the wire guide after installation.

[0041] The second bolt 12 is threaded onto the side end of the mounting block 9. After tightening the second bolt 12, its side end abuts against the side end of the sliding frame 8, thereby fixing the position of the mounting block 9 and further stabilizing the structure of the wire guide after installation, ensuring its stability during use.

[0042] Working principle:

[0043] The first step is to slide the sliding frame 8 and mounting block 9 according to the position of the mounting holes, so that the mounting block 9 can be aligned with the position of the mounting holes. After all four mounting blocks 9 are aligned, tighten the first bolt 11, so that the first bolt 11 and the sliding frame 8 clamp the mounting base 1, thus fixing the position of the sliding frame 8. Then tighten the second bolt 12, and the side end of the second bolt 12 will abut against the side end of the sliding frame 8, thus fixing the mounting block 9. After the mounting base 1 is installed, the knob 7 can be turned to rotate the threaded rod 6. Since the threaded rod 6 is threadedly connected to the lifting frame 2, it can drive the lifting frame 2 to slide up and down, thus achieving the effect of easy adjustment according to the installation requirements.

[0044] Secondly, during use, the two ceramic guide wheels 4 are restricted by two meshing herringbone gears 5 on their sides, and will rotate synchronously. This prevents the two ceramic guide wheels 4 from rotating asynchronously due to jamming of one ceramic guide wheel 4 when pulling the wire, which would cause uneven force on both ends of the wire and changes in tension. The ceramic bearing 3 between the ceramic guide wheel 4 and the lifting frame 2 can reduce the friction during the rotation of the ceramic guide wheel 4 and improve the stability of the rotation of the ceramic guide wheel 4. At the same time, the two helix angles of the herringbone gears 5 are equal and the directions of rotation are opposite. When the two herringbone gears 5 mesh with each other, they will restrain each other and prevent the two herringbone gears 5 from generating axial force, thus curbing the axial deflection of the two ceramic guide wheels 4. This effectively prevents the wire from jumping due to axial deviation.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
