Description

Technical Field

[0001] This utility model relates to the field of textile machinery, and in particular to a stabilizer that can reduce the swaying of yarn bundles. Background Technology

[0002] This stabilizer is mainly used in the processing of filaments in the chemical fiber and textile industries, such as drawing and winding. It is widely used in the production of chemical fiber filaments and textile pretreatment. Its core function is to reduce the left and right deviation and up and down bounce during the filament conveying process and ensure the stability of the filament posture. Currently, the stabilizers on the market mainly consist of an L-shaped fixed bracket, parallel guide wheels, and a simple elastic pressure plate. They mainly reduce the filament sway and ensure smooth subsequent processing by using the guiding and limiting action of the guide wheels and the slight pressing action of the pressure plate. Existing filament stabilizers are complex to operate when adjusting the guide wheel spacing when dealing with filaments of different thicknesses. Furthermore, traditional pressing plates can easily scratch or even break the filaments. Therefore, a stabilizer that can reduce filament sway is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a stabilizer that can reduce the swaying of the filament bundle, aiming to improve the problem of the relatively complicated operation of adjusting the spacing of the guide wheels.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a stabilizer that can reduce the swaying of the filament bundle, comprising a bracket, a first rotating shaft rotatably connected inside the bracket, a first guide wheel fixedly connected to the outside of the first rotating shaft, long grooves formed on both outer walls of the bracket, a second rotating shaft movably connected to the inner wall of the long groove, a second guide wheel fixedly connected to the outside of the second rotating shaft, a fixed rotating ring rotatably connected to the outside of the second rotating shaft, a support shaft fixedly connected to the top of the fixed rotating ring, support plates fixedly connected to both outer walls of the bracket, a spring sleeved on the outside of the support shaft, and a stop plate fixedly connected to the top of the support shaft.

[0005] As a further description of the above technical solution: Two sliding grooves are provided on both outer walls of the bracket. A stabilizing plate is slidably connected to the inner wall of the sliding groove. Four fixing blocks are fixedly connected to both outer walls of the bracket. A threaded rod is rotatably connected between two adjacent fixing blocks. The stabilizing plate is threadedly connected to the outer wall of the threaded rod.

[0006] As a further description of the above technical solution: The outer walls of the first guide wheel and the second guide wheel are both provided with annular grooves. The stabilizer is rotatably connected inside the stabilizer plate. The two ends of the first rotating shaft are fixedly connected with limit plates, and the limit plates abut against the outer wall of the bracket.

[0007] As a further description of the above technical solution: An operating shaft is fixedly connected to the top of the threaded rod, and a pentagonal groove is provided on the top of the operating shaft.

[0008] As a further description of the above technical solution: The outer wall of the steady plate abuts against the inner wall of the chute.

[0009] As a further description of the above technical solution: The bracket has a threaded connection to the bottom wall inside, and the bracket is detachably and fixedly connected to the outside of the device by the fixing bolt.

[0010] As a further description of the above technical solution: The abutment plate abuts against the top of the support plate, one end of the spring is fixedly connected to the bottom wall of the support plate, and the other end of the spring is fixedly connected to the outer wall of the fixed rotating ring.

[0011] This utility model has the following beneficial effects: 1. In this utility model, the distance between the movable second guide wheel and the first guide wheel is adjusted, and with the continuous contact force provided by the spring, it can automatically adapt to filament bundles of different thicknesses; at the same time, the height of the stabilizing plate is precisely adjusted by the threaded rod, so that the stabilizing structure is always aligned with the filament bundle path, and stable constraint can be achieved without complicated operation, making the adaptation process convenient and efficient.

[0012] 2. In this utility model, the annular groove of the guide wheel restricts the left and right displacement of the filament bundle to prevent it from falling off and scratching; the steady wheel rotates synchronously with the filament bundle to provide flexible constraint, and the spring applies uniform and moderate contact pressure to the guide wheel to avoid excessive local pressure. The entire constraint process is gentle and without hard friction, which greatly reduces the risk of the filament bundle being scratched or broken. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Reference Figures 1-5 An embodiment of this utility model provides a stabilizer that can reduce the swaying of the filament bundle, comprising a bracket 1, a first rotating shaft 2 rotatably connected inside the bracket 1, a first guide wheel 3 fixedly connected to the outside of the first rotating shaft 2, long grooves 8 on both outer walls of the bracket 1, a second rotating shaft 4 movably connected to the inner wall of the long grooves 8, a second guide wheel 5 fixedly connected to the outside of the second rotating shaft 4, a fixed rotating ring 9 rotatably connected to the outside of the second rotating shaft 4, a support shaft 10 fixedly connected to the top of the fixed rotating ring 9, support plates 11 fixedly connected to both outer walls of the bracket 1, a spring 13 sleeved on the outside of the support shaft 10, and a stop plate 12 fixedly connected to the top of the support shaft 10.

[0017] The first guide wheel 3 achieves stable rotation via the first rotating shaft 2, providing basic guiding support for the filament bundle. The second rotating shaft 4 can move flexibly along the extension direction of the long groove 8, thereby driving the second guide wheel 5 to adjust the distance between itself and the first guide wheel 3 to accommodate filament bundles of different thicknesses. The spring 13 is located between the support plate 11 and the fixed rotating ring 9, and applies a continuous downward force to the fixed rotating ring 9 through its own elastic tension. This force is transmitted to the second rotating shaft 4 and the second guide wheel 5, so that the second guide wheel 5 always tends to move closer to the first guide wheel 3, ensuring that regardless of the thickness of the filament bundle, the two guide wheels can fit tightly against the surface of the filament bundle, initially limiting the swaying space of the filament bundle. The abutment plate 12 abuts against the top of the support plate 11, which can effectively limit the upward movement of the support shaft 10, prevent the spring 13 from being overstretched and failing, and ensure the stable operation of the guiding structure.

[0018] Reference Figure 1 , Figure 2 and Figure 4Two sliding grooves 14 are provided on both outer walls of the bracket 1. A stabilizing plate 15 is slidably connected to the inner wall of the sliding groove 14. Four fixing blocks 16 are fixedly connected to both outer walls of the bracket 1. A threaded rod 17 is rotatably connected between two adjacent fixing blocks 16. The stabilizing plate 15 is threadedly connected to the outer wall of the threaded rod 17.

[0019] The slide 14 provides precise sliding guidance for the steady plate 15, ensuring that the steady plate 15 can only move up and down along the vertical direction of the slide 14, avoiding deviation during movement; the fixed block 16 provides a stable support point for the threaded rod 17, enabling the threaded rod 17 to rotate smoothly without displacement; when the threaded rod 17 rotates, the rotational motion is converted into the linear motion of the steady plate 15 by utilizing the principle of thread transmission. By rotating the threaded rod 17, the height position of the steady plate 15 can be flexibly adjusted, so that the steady structure on the steady plate 15 can be precisely aligned with the conveying path of the filament bundle, further enhancing the steady constraint effect on the filament bundle.

[0020] Reference Figure 5 The outer walls of the first guide wheel 3 and the second guide wheel 5 are both provided with annular grooves 6. The inside of the stabilizing plate 15 is rotatably connected to a stabilizing wheel 18. The two ends of the first rotating shaft 2 are fixedly connected to limiting circular plates 7, which abut against the outer wall of the bracket 1.

[0021] The shape of the annular groove 6 is adapted to the shape of the filament bundle. During the conveying process, the filament bundle is embedded in the annular groove 6, which can effectively limit the offset of the filament bundle in the left and right directions and prevent the filament bundle from falling off the guide wheel. The stabilizing wheel 18 can rotate synchronously with the movement of the filament bundle. Without affecting the normal conveying of the filament bundle, it can apply flexible constraints from the side or top of the filament bundle to further suppress the up-and-down bouncing and irregular shaking of the filament bundle. The limiting circular plate 7 can limit the movement of the first rotating shaft 2 in the axial direction by abutting against the outer wall of the bracket 1, so as to prevent the first guide wheel 3 from deviating from the filament conveying path due to axial displacement and ensure the guiding accuracy and stability of the first guide wheel 3.

[0022] Reference Figure 2 The top of the threaded rod 17 is fixedly connected to the operating shaft 19, and the top of the operating shaft 19 is provided with a pentagonal groove 20.

[0023] The operating shaft 19 extends the operating end of the threaded rod 17, making it convenient for the operator to rotate and adjust the threaded rod 17 from above. The pentagonal groove 20 is compatible with the pentagonal wrench, which can increase the fit and friction between the tool and the operating shaft 19, avoid slippage during adjustment, and enable the operator to control the rotation angle of the threaded rod 17 more effortlessly and accurately, thereby precisely adjusting the position of the steady plate 15, improving the convenience of operation and adjustment accuracy.

[0024] Reference Figure 2 The outer wall of the steady plate 15 abuts against the inner wall of the groove 14.

[0025] The tight contact between the outer wall of the stabilizing plate 15 and the inner wall of the slide groove 14 eliminates the gap between them, preventing the stabilizing plate 15 from swaying or shifting laterally during sliding or operation. This close-fitting design ensures that the movement trajectory of the stabilizing plate 15 remains accurate, enabling the stabilizing wheel 18 to continuously align with the constraint position of the filament bundle, ensuring the consistency and stability of the stabilizing effect, and preventing the constraint effect on the filament bundle from being affected by the swaying of the stabilizing plate 15.

[0026] Reference Figure 1 The bottom wall of the bracket 1 is threaded with a fixing bolt 21, and the bracket 1 is detachably fixed to the outside of the device by the fixing bolt 21.

[0027] The fixing bolt 21 can firmly fix the bracket 1 to the external processing device, so that the entire stabilizer will not shift due to equipment vibration or the force of the filament bundle during operation, ensuring the relative position stability of the stabilizer and the filament bundle conveying path; at the same time, the detachable connection method allows operators to flexibly adjust the installation position of the stabilizer according to actual processing needs, or disassemble the stabilizer for maintenance and replacement of parts, improving the versatility and ease of maintenance of the equipment.

[0028] Reference Figures 1-3 The abutment plate 12 abuts against the top of the support plate 11, one end of the spring 13 is fixedly connected to the bottom wall of the support plate 11, and the other end of the spring 13 is fixedly connected to the outer wall of the fixed rotating ring 9.

[0029] The contact between the abutment plate 12 and the support plate 11 defines the maximum upward movement distance of the support shaft 10, preventing the spring 13 from being overstretched and exceeding its elastic limit, thereby protecting the elastic performance of the spring 13 and extending its service life. The two ends of the spring 13 are fixed to the support plate 11 and the fixed rotating ring 9 respectively, forming a stable elastic support structure. When the spacing of the second guide wheel 5 is adjusted to accommodate different thicknesses of filaments, the spring 13 will be compressed or stretched accordingly. Through the elastic restoring force, it always provides uniform and continuous pressure to the second guide wheel 5, ensuring that the second guide wheel 5 and the filaments maintain a suitable contact force, which not only constrains the filaments but also prevents damage to the filaments due to excessive pressure.

[0030] Working principle: The bracket 1 is detachably fixed to the outside of the device by fixing bolts 21, providing stable support for the overall structure. The first guide wheel 3 achieves stable rotation through the first rotating shaft 2. The second rotating shaft 4 can move flexibly along the long grooves 8 on both sides of the bracket 1, driving the second guide wheel 5 to adjust the distance between it and the first guide wheel 3. The spring 13 between the support plate 11 and the fixed rotating ring 9, through elastic tension, makes the second guide wheel 5 always tend to move closer to the first guide wheel 3, adapting to wire bundles of different thicknesses. The abutment plate 12 abuts against the top of the support plate 11 to limit the upward movement of the support shaft 10 and prevent the spring 13 from being overstretched and failing. The limiting circular plates 7 at both ends of the first rotating shaft 2 abut against the outer wall of the bracket 1 to prevent the first guide wheel 3 from shifting axially. The sliding grooves 14 on both sides of the frame 1 provide precise guidance for the stabilizing plate 15. The threaded rod 17 supported by the fixed block 16 drives the stabilizing plate 15 to move up and down through the threaded transmission. The operator can adjust the threaded rod 17 with ease and precision by using the operating shaft 19 with the pentagonal groove 20 on the top. The outer wall of the stabilizing plate 15 is in close contact with the inner wall of the sliding groove 14 to avoid lateral swaying. The stabilizing wheel 18 connected inside rotates synchronously with the filament bundle to apply flexible constraints. The annular grooves 6 on the outer walls of the first guide wheel 3 and the second guide wheel 5 restrict the left and right deviation of the filament bundle. All components work together to suppress the left and right deviation and up and down bouncing of the filament bundle from multiple aspects such as guidance, spacing adaptation, and flexible constraints, and finally achieve the effect of reducing filament bundle swaying and ensuring stable filament bundle delivery.

[0031] 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.
