DETAILED DESCRIPTION

[0028] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0029] Referring to Figures 1-6 The utility model provides a kind of wear-resistant composite spinning roller for producing aluminum silicate fiber, including roller main body 1, support seat 2, fixed component 3 and wear-resistant component 4.

[0030] The roller body 1 is the basic structure of the spinning roller. During the production of aluminosilicate fibers, centrifugal force is generated by high-speed rotation, causing the aluminosilicate fiber raw material to be thrown out and shaped. The support base 2 is installed on both sides of the roller body 1 to provide support for the roller body 1. The design of the support base 2 has sufficient strength and stability to withstand the weight of the roller body 1 and various forces and vibrations generated during operation. Its connection with the roller body 1 is firm and reliable, ensuring that the roller body 1 will not shake or shift during high-speed rotation. At the same time, the support base 2 also provides the mounting base for the fixing component 3, making the entire spinning roller structure more stable. The fixing component 3 is installed on the support base 2, and its function is to further fix the roller body. 1. To prevent loosening or displacement during operation, the wear-resistant component 4 is used to improve the wear resistance of the spinning roller. The main ring 5 is detachably connected to the roller body 1. This detachable design facilitates replacement and maintenance when the main ring 5 or its internal components are worn or damaged. A sliding ring 6 is slidably arranged on the inner wall of the main ring 5, providing a track for the movement of the sliding ring 6. At least four first connecting plates 7 are fixedly arranged on the sliding ring 6. These first connecting plates 7 provide the mounting base for the subsequent rotating structure. A first rotating shaft 8 is rotatably arranged between each first connecting plate 7, allowing the first connecting plates 7 to rotate relative to each other, increasing the flexibility of the structure. A rotating shaft 8 is rotatably arranged on the first rotating shaft 8. The rotating plate 9 has a second rotating shaft 10 rotatably mounted at its bottom. Through the rotatable connection of the first rotating shaft 8 and the second rotating shaft 10, the rotating plate 9 can rotate in multiple directions to better adapt to different working requirements. Second connecting plates 11, corresponding in number to the first connecting plates 7, are rotatably mounted on both sides of the second rotating shaft 10. A push ring 12 is connected to the bottom of the second connecting plate 11, and a rubber ring 13 is fixedly mounted at the bottom of the push ring 12. The rubber ring 13 is in contact with the surface of the roller body 1. The rubber ring 13 has good wear resistance and elasticity, effectively reducing wear on the surface of the roller body 1, and also providing a certain buffering effect to protect the roller body 1 and the side of the main ring 5. A fixed plate 14 is provided, corresponding to the number of rotating plates 9. A rotating shaft 15 is rotatably mounted on the fixed plate 14. The rotating shaft 15 passes through the rotating plate 9 and rotates with the rotating plate 9. The setting of the rotating shaft 15 allows the rotating plate 9 to rotate around it, further adjusting the degree of contact and pressure between the rubber ring 13 and the surface of the roller body 1. A pull post 28 is fixedly mounted at one end of the sliding ring 6. A third nut 29 is fixedly mounted at the top of the pull post 28. The third nut 29 is in contact with the main ring 5. By adjusting the third nut 29, the position of the sliding ring 6 on the inner wall of the main ring 5 can be controlled, thereby adjusting the contact between the rubber ring 13 and the surface of the roller body 1 to adapt to different working conditions and wear levels.

[0031] First, refer to Figure 2 and Figure 3In this embodiment, the fixing component 3 includes a third connecting plate 16, which is fixed to both sides of the support base 2, providing the foundation for the entire fixing structure. A fixing ring 17 is rotatably mounted on the third connecting plate 16. This design allows the fixing ring 17 to rotate flexibly, facilitating position adjustment to fit the roller body 1. A vertical plate 18 is fixed to the top of the fixing ring 17, and a threaded hole 19 is opened between the two vertical plates 18. A screw 20 is screwed into the hole through the thread. One end of the screw 20 is engaged with a first nut 21. When the first nut 21 is tightened, it fits tightly against the vertical plate 18, thereby adjusting the tightness of the screw 20 and thus adjusting the position of the fixing ring 17. Precise locking ensures that the roller body 1 is firmly clamped. The inner wall of the fixing ring 17 is provided with a first rubber plate 22, which is in contact with the surface of the roller body 1. The first rubber plate 22 is soft and has a certain elasticity, which can not only enhance the friction and prevent the roller body 1 from sliding in the fixing ring 17, but also avoid damage to the surface of the roller body 1 caused by hard contact. A rubber patch 30 with friction points 31 is fixed on the side of the vertical plate 18 located on one side. With its own flexibility and friction, the rubber patch 30 can effectively increase the friction when in contact with other components, further improving the stability of the fixing component 3 and reducing the risk of displacement caused by vibration or external force.

[0032] Then, refer to Figure 4 In this embodiment, slits 23 are provided on the main ring 5, the sliding ring 6, and the rubber ring 13. The slits 23 on the main ring 5 make the main ring 5 more flexible during installation and disassembly. It can be easily connected or separated from the roller body 1 by moderately expanding or contracting, reducing installation difficulty and maintenance costs. The slits 23 on the sliding ring 6 also facilitate its sliding on the inner wall of the main ring 5. When it is necessary to adjust the position of the sliding ring 6 to change the fit between the rubber ring 13 and the roller body 1, the slits 23 allow the sliding ring 6 to move more smoothly and will not get stuck due to size fit issues. The slits 23 on the rubber ring 13 help it better adapt to the surface shape of the roller body 1 and the stress changes during operation. During the operation of the spinning roller, the rubber ring 13 is subjected to various forces. The slits 23 can deform the rubber ring 13 to a certain extent, evenly disperse the stress, avoid local stress concentration leading to premature wear or damage, and extend the service life of the rubber ring 13.

[0033] Finally, see Figure 6In the embodiment, the clamping plates 24 are detachably installed on both sides of the main ring 5, two sliding grooves 25 are formed in the clamping plates 24, the limiting columns 26 are installed on both sides of the main ring 5 through threads, the limiting columns 26 are in sliding cooperation with the sliding grooves 25, the second nuts 27 are screwed on one end of the limiting columns 26, the second nuts 27 are attached to the clamping plates 24, when it is necessary to fix the position of the main ring 5, the second nuts 27 are screwed to extrude the clamping plates 24, the limiting columns 26 are fixed at the current position by means of the friction force, thereby limiting the movement of the main ring 5, this design is convenient for adjusting the position of the main ring 5 during installation and debugging, and can ensure the stability of the main ring 5 during work, prevent the displacement of the main ring 5 due to vibration or other external force, guarantee the stable operation of the wear-resistant assembly 4, and improve the wear resistance and work reliability of the spinning roller.
