The grinder consists of a control base, a fixed rod, a mounting block, a fastening screw, a rotating block, a sliding block, a motor, a grinding rod, a lighting lamp, a magnetic base, and a magnetic clamp. When grinding dentures, the denture holder is fixed by twisting the screw on the magnetic clamp, cooperating with the clamping block and the fixing column, adjusting the position of the mounting block on the fixed rod and fixing it by fastening the screw. Then turn on the start button on the control base, the motor drives the grinding rod to rotate, and the lighting lamp illuminates the denture. The lighting lamp can be adjusted in position, and the worker can rotate the rotating block and slide the sliding block to adjust the position of the grinding rod. At the same time, the worker holds the magnetic clamp with his other hand and moves it on the magnetic base to adjust the position of the denture. When the magnetic clamp and the magnetic base are close to each other, they attract each other, so that the grinding rod contacts the denture for grinding.

By setting the protective component 2, when the denture is ground, the sliding block 10 moves, so that the grinding rod contacts the denture, and at the same time, the transparent bellows 22 at the lower end of the mounting cylinder 21 covers the grinding rod and the denture, so that the dust generated by the grinding is blocked, and the suction mechanism 23 collects the dust, thereby preventing the scattered dust from being inhaled into the respiratory tract of the staff as much as possible. The arc surface of the mounting cylinder 21 is detachably connected to the mounting plate 24, and a reset spring 25 is fixedly connected between the mounting plate 24 and the transparent bellows 22. By setting the mounting plate 24 and the reset spring The positioning spring 25 squeezes the transparent bellows 22 so that it fits tightly with the denture bracket. The lower end of the transparent bellows 22 is fixedly connected to a sealing pad 26, which assists the transparent bellows 22 to fit tightly with the denture bracket. The suction mechanism 23 includes a collecting box 231 detachably connected to the right end of the rotating block 9. A lid 233 is installed at the upper end of the collecting box 231. A collecting pipe 234 is fixedly connected between the lid 233 and the mounting cylinder 21.

When it is necessary to replace a grinding rod with a different mesh number, the grinding ring 33 is screwed to separate it from the connecting shaft 31, and then the grinding ring 33 with the required mesh number is replaced, thereby completing the replacement of grinding rods with different mesh numbers. The arc surface of the connecting shaft 31 is fixedly connected to a limiting ring 32, and the thread direction between the grinding ring 33 and the connecting shaft 31 is consistent with the rotation direction of the connecting shaft 31. The grinding ring 33 is limited by setting the limiting ring 32.

[0029] Working principle:

[0030] When grinding the denture, the denture holder is fixed by twisting the screw on the magnetic clamp 8, cooperating with the clamping block and the fixing column, adjusting the position of the mounting block 6 on the fixing rod 5, and fixing it by tightening the screw 7, then turning on the start button on the control base 1, the motor 11 drives the grinding rod to rotate, and the lighting lamp 12 illuminates the denture, and the lighting lamp 12 can be adjusted in position. The worker can rotate the rotating block 9 and the sliding block 10 to adjust the position of the grinding rod. At the same time, the worker holds the magnetic clamp 8 with his other hand and moves on the magnetic base 4 to adjust the position of the denture. When the magnetic clamp 8 and the magnetic base 4 are close to each other, they attract each other, so that the grinding rod and the denture are in contact for grinding. When grinding the denture, when the sliding block 10 moves, the grinding rod is in contact with the denture, and at the same time, the transparent bellows 22 at the lower end of the mounting cylinder 21 covers the grinding rod and the denture, so that the dust generated by grinding is blocked, and at the same time, the high-pressure fan 235 is started to make the collection box Negative pressure is generated in 231, so that negative pressure is generated in the collection box 231, so that the collection tube 234 on the cover 233 collects the dust into the collection box 231, and the dust falling into the collection box 231 is collected by the collection net 232, which collects the dust and thus avoids the scattered dust from being inhaled into the respiratory tract of the staff as much as possible. By setting the mounting plate 24 and the return spring 25, the transparent bellows 22 is squeezed to fit tightly with the denture bracket, and the sealing cushion 26 assists the transparent bellows 22 to fit tightly with the denture bracket. When it is necessary to replace the grinding rod of different mesh size, the grinding ring 33 is twisted to separate it from the connecting shaft 31, and then the grinding ring 33 of the required mesh size is replaced, thereby completing the replacement of the grinding rod of different mesh size. The thread direction between the grinding ring 33 and the connecting shaft 31 is consistent with the rotation direction of the connecting shaft 31, and the grinding ring 33 is limited by setting the limit ring 32.
