As the grinding sheet 7 continues to rotate, the grinding sheet 7 can grind different positions on the bottom edge of the ceramic product.

[0025] Working principle: During operation, the ceramic product to be polished passes through the annular box 10, and the bottom of the ceramic product contacts the top of the polishing disc 7. The ceramic product is fixedly mounted on the annular box 10 through the ceramic product clamping structure. The first rotating shaft 3 is driven to rotate by the driver. The first rotating shaft 3 drives the supporting plate 6 and the polishing disc 7 to rotate through the first prism 5. The polishing disc 7 polishes the bottom of the ceramic product. When the edge position of the bottom of the ceramic product needs to be polished, the polishing disc 7 and the supporting plate 6 are driven to move downward relative to the mounting table 1 by the hydraulic telescopic rod 9, and the position adjustment component is changed. By changing the inclination angle of the swing frame 13, the inclination angles of the support sleeve 12, the rotating sleeve 11, the annular box 10 and the ceramic product are changed synchronously, and the edge position of the bottom of the ceramic product contacts the grinding sheet 7. At the same time, the position adjustment component drives the rotating sleeve 11, the annular box 10 and the ceramic product to rotate synchronously, so that different positions on the bottom edge of the ceramic product can contact the grinding sheet 7. As the grinding sheet 7 continues to rotate, the grinding sheet 7 can grind different positions on the bottom edge of the ceramic product, without the need for manual grinding by the staff, thereby improving the grinding efficiency; When the supporting plate 6 and the grinding disc 7 move downward, the annular box 10 and the ceramic product move downward synchronously, and the annular box 10 and the ceramic product tilt, the swing frame 13 drives the rotating box 14 to rotate relative to the fixed box 15 and the connecting shaft 16, and the first bevel gear 22 rolls on the second bevel gear 23. When the first rotating shaft 3 rotates, the first rotating shaft 3 drives the fourth bevel gear 27 to rotate, and the fourth bevel gear 27 drives the worm 25 to rotate through the third bevel gear 26. The worm 25 can drive the connecting shaft 16 and the second bevel gear 23 to rotate at a reduced speed through the worm gear 24. The second bevel gear 23 drives the second rotating shaft 19 and the first gear 20 to rotate through the first bevel gear 22. The first gear 20 can drive the ring gear 18, the rotating sleeve 11 and the annular box 10 to rotate relative to the supporting sleeve 12 through the second gear 21, so that the tilted ceramic product rotates and the position of the ceramic product is changed; The staff drives the support ring 28 and the fixing frame 37 to move downward, the tension spring 40 is in a tensioned state, and the first compression spring 32 is in a compressed state at this time, the first compression spring 32 drives the movable plate 29 to move horizontally, so that the end of the support column 30 away from the movable plate 29 slides on the inclined surface of the support ring 28, and the movable plate 29 drives the second prism 31 and the slider 34 to move synchronously, and several sliders 34 all move toward a position away from the center of the annular box 10, so that the spacing between several sliders 34 is sufficient to place ceramic products, pass the ceramic products through the middle of the annular box 10, and the bottom of the ceramic products contacts the top of the grinding sheet 7. The staff releases the support ring 28, and the tension spring 40 drives the fixing frame 37 and the support ring 28 to move upward, and the support ring 28 Push the support column 30 to move in the opposite horizontal direction, and the support column 30 can drive the movable plate 29, the second prism 31 and the slider 34 to move synchronously, and the rubber pad 36 contacts the ceramic product. As the support column 30, the movable plate 29 and the second prism 31 continue to move, the length of the slider 34 in the groove 33 becomes longer, and the second compression spring 35 applies pressure to the slider 34, so that the plurality of rubber pads 36 elastically clamp the ceramic product, so that the ceramic product can be fixed relative to the annular box 10. When the annular box 10 rotates relative to the support sleeve 12, the annular box 10 drives the support column 30 to rotate on the inner wall of the support ring 28, and the support column 30 remains stationary relative to the annular box 10. Therefore, the rotation of the annular box 10 will not affect the ceramic product being clamped and fixed by the plurality of rubber pads 36. The fourth gear 43 is driven to rotate by the motor 42, and the fourth gear 43 can drive the first rotating shaft 3 to rotate through the third gear 41. When the grinding sheet 7 needs to be removed and replaced, the staff drives the handle 49 to move horizontally, and the handle 49 drives the plug plate 45 to disengage from the positioning plate 44, thereby releasing the limitation on the position of the positioning plate 44. The third compression spring 48 is in a compressed state, and the staff drives the grinding sheet 7 to move upward relative to the support plate 6 to make the positioning plate 44 disengage from the support plate 6. The positioning plate 44 is no longer located on one side of the plug plate 45, and the grinding sheet 7 can be removed, which is convenient for replacing the grinding sheet 7.
