[0022] Reference Figures 1 to 5In the embodiment of the utility model, a threaded metal-ceramic composite roller that is convenient for adjusting the wear-resistant ring includes: a roller body 1, a roller inner cavity 2 is opened on the inner side of the roller body 1, and the roller inner cavity 2 is fixedly connected to two groups of fixing seats 3, and the two groups of fixing seats 3 are symmetrically arranged on the inner wall of the roller inner cavity 2. A bidirectional threaded rod 4 is rotatably connected to the inner side of the fixing seat 3, and one end of the bidirectional threaded rod 4 is fixedly connected to the first bevel gear 5. A dual-axis motor 6 is fixedly connected to the inside of the roller body 1, and the two rotating shafts of the dual-axis motor 6 are respectively fixedly connected to an extended cross rod 7, and one end of the extended cross rod 7 is fixedly connected to the rotating shaft of the dual-axis motor 6. A second bevel gear 8 is fixedly connected to the outside of the extended cross rod 7, and one end of the bidirectional threaded rod 4 passes through the inside of the roller body 1 and is fixedly connected to the first bevel gear 5. The dual-axis motor 6, the extended cross rod 7 and the second bevel gear 8 are all located inside the roller body 1, and the first bevel gear 5 is meshed with the second bevel gear 8. Two groups of arc-shaped wear-resistant rings 9 are arranged inside the inner cavity 2 of the roller. Two groups of screw hole blocks 10 are symmetrically fixedly connected to the outside of each group of arc-shaped wear-resistant rings 9. The inner side of the screw hole block 10 is provided with a threaded hole adapted to the bidirectional threaded rod 4. The screw hole block 10 is threadedly connected to the bidirectional threaded rod 4 through the threaded hole opened on the inner side. Arc-shaped slide grooves 11 are provided above and below the arc-shaped wear-resistant ring 9. Two groups of arc-shaped extrusion plates 12 are provided above and below the arc-shaped wear-resistant ring 9. Two groups of circular sliders 13 are fixedly connected to the side of each group of arc-shaped extrusion plates 12, and the circular sliders 13 are adapted to the arc-shaped slide grooves 11. When the two groups of arc-shaped wear-resistant rings 9 are tightened inward, the circular sliders 13 drive the arc-shaped extrusion plates 12 to be tightened inward under the guidance of the arc-shaped slide grooves 11, thereby fixing the roller shaft. Extrusion gaskets 14 are fixedly connected to the inner sides of the two groups of arc-shaped wear-resistant rings 9, which are used to enhance the fit between the inner sides of the arc-shaped wear-resistant rings 9 and the roller shaft, thereby enhancing the anti-slip performance.

[0023] The working principle of the utility model is as follows: when the metal-ceramic composite roller needs to be fixed, the roller shaft is inserted into the roller inner cavity 2, and the dual-axis motor 6 is started. The two rotating shafts of the motor respectively drive the two extended cross bars 7 to rotate, and the second bevel gear 8 fixed on the outside of the extended cross bars 7 rotates accordingly and meshes with the first bevel gear 5, thereby driving the bidirectional threaded rod 4 to rotate in the fixed seat 3;

[0024] Each set of bidirectional threaded rods 4 is symmetrically connected to two screw hole blocks 10 with screw hole blocks 10, which are respectively fixedly connected to the outer sides of the two sets of arc-shaped wear-resistant rings 9. When the bidirectional threaded rods 4 rotate, due to the interaction of the threads, the two screw hole blocks 10 will move relative to or away from each other along the axial direction of the bidirectional threaded rods 4, thereby driving the arc-shaped wear-resistant rings 9 to adjust inward or outward to clamp the roller shaft. After the roller shaft is clamped, the dual-axis motor 6 is turned off, and the rotating shaft of the dual-axis motor 6 and the extended cross bar 7 are locked accordingly;

[0025] Arc-shaped extrusion plates 12 are provided above and below the arc-shaped wear-resistant ring 9. These extrusion plates cooperate with the arc-shaped slide groove 11 through the circular slider 13 fixed on the side to achieve sliding connection. When the arc-shaped wear-resistant ring 9 is tightened inward, the circular slider 13 drives the arc-shaped extrusion plate 12 to tighten inward under the guidance of the arc-shaped slide groove 11, thereby achieving secondary clamping and fixation of the roller shaft. This design not only enhances the fit between the wear-resistant ring and the roller shaft, but also improves the anti-slip performance. The extrusion gasket 14 fixedly connected to the inner side of the arc-shaped wear-resistant ring 9 further enhances the fit between the wear-resistant ring and the roller shaft, improves the anti-slip effect, and ensures that it can remain stable when running at high speed or under high pressure.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
