The horizontal plate 27 and two groups of rollers 7 are rotatably connected. A power structure is arranged outside the support frame 6.

[0037] The power structure includes a fixed frame 28, which is fixedly installed above the processing frame 1. An electric push rod 29 is fixedly installed above the fixed frame 28. The output end of the electric push rod 29 passes through the fixed frame 28 and extends to the bottom of the fixed frame 28.

[0039] Working principle: The ceramic product to be polished is placed on the top of the workbench 2, the fixture 3 clamps the ceramic product, the motor 18 is connected to the external power supply, the motor 18 drives the No. 3 gear 17 to rotate, and since the No. 3 gear 17 is meshed with the two groups of No. 2 gears 15, the two groups of No. 2 gears 15 can rotate in opposite directions, one group of No. 2 gears 15 drives the workbench 2 to rotate above the processing frame 1, and the other group of No. 2 gears 15 drives the rotating shaft 8 to rotate through the connecting rod 16.

[0040] When the ceramic product is placed on the workbench 2, the outer surface of the ceramic product is in contact with the grinding belt 4, and the rotating shaft 8 drives the No. 1 gear 13 to rotate. Under the action of the toothed belt 14, the rotating shaft 8 can drive the roller 7 to rotate, thereby driving the grinding belt 4 and the workbench 2 to rotate in the opposite direction, so that after the grinding belt 4 grinds the surface of the ceramic product, the grinding belt 4 with residual particles can move, so that the grinding belt 4 with particles will not grind the surface of the ceramic product.

[0041] At the same time, the roller 7 drives the protrusion 19 to rotate synchronously when it rotates. Since the upper end surface of the protrusion 19 is inclined and the protrusion 19 is in contact with the support plate 20, the protrusion 19 can push the support plate 20 to move upward when it rotates, and the support plate 20 drives the brush 5 to move synchronously. At this time, the column 22 moves upward inside the slider 21. When the protrusion 19 is not in contact with the support plate 20, the support plate 20 moves downward under the action of gravity, thereby driving the brush 5 to move downward. The brush 5 can clean the surface of the grinding belt 4 when it moves, and remove the particles attached to the surface of the grinding belt 4.

[0042] Furthermore, under the action of the fixing frame 28, the electric push rod 29 is connected to the external power supply, and the electric push rod 29 drives the support frame 6 to move up and down through the fixing plate 30, thereby driving the grinding belt 4 to move synchronously, which is convenient for grinding the outer surface of the ceramic product.

[0043] During this process, since the outer surface of the ceramic product is a curved surface, when the grinding belt 4 moves to a position where the cross-section of the ceramic product is larger, the ceramic product squeezes the grinding belt 4, so that the two groups of rollers 7 close to the ceramic product can move away from each other, thereby driving the two groups of connecting frames 9 to rotate around the rotating shaft 8, and the other two groups of rollers 7 drive the connecting seat 11 to slide on the outer surface of the cross bar 10, and the spring 12 is deformed by the force. At this time, the part of the grinding belt 4 that contacts the ceramic product moves toward the direction of the rotating shaft 8, and the contact part of the grinding belt 4 with the ceramic product increases, which is convenient for grinding the outer surface of the ceramic product, so that the grinding belt 4 can automatically adjust its position according to the curved surface of the ceramic product, and the device has a wider range of applications.

[0044] At the same time, when the roller shaft 7 moves, it can drive the cross plate 27 to move inside the support frame 6. Under the action of the fourth gear 25, the cross plate 27 drives one set of racks 26 to move, so that the mounting plate 24 can be driven to move synchronously through the other set of racks 26. The cross plate 27 and the mounting plate 24 can approach or move away from each other. The mounting plate 24 can drive the smearing piece 23 to move, and the smearing piece 23 applies the polishing paste or polishing powder to the outer surface of the ceramic product. It should be noted that the mounting plate 24 and the cross plate 27 are symmetrically arranged through the central axis of the workbench 2, so that the smearing piece 23 can adjust its position according to the curved surface of the ceramic product.
