[0022] Furthermore, the outer surface of the holding sleeve 1 is fixedly connected to an air pipe 71, one end of the air pipe 71 is fixedly connected to a metal molding tube 72, one end of the rotating shaft 6 is fixedly connected to an annular rotating block 73, and the air inlet hole 4 serves to cooperate with the airflow movement when the fan disk 7 rotates, and the metal molding tube 72 serves to facilitate the adjustment of the angle of the airflow ejection, thereby improving the dust removal effect.

[0023] Furthermore, a slot 74 is provided on one side surface of the annular rotating block 73 , and symmetrically distributed slots 75 are provided on the inner walls of both sides of the slot 74 . An extrusion plate 76 is movably sleeved on the inner wall of the slot 75 , and the extrusion plate 76 serves to limit the movement inside the slot 75 .

[0024] Furthermore, a driving rod 77 is fixedly connected to one side surface of the extrusion plate 76 , and one end of the two driving rods 77 penetrates and extends to the outer surface of the annular rotating block 73 , and the driving rod 77 serves to facilitate driving the extrusion plate 76 for extrusion.

[0025] Furthermore, a pressure block 78 is fixedly connected to one end of the driving rod 77, an insert block 79 is movably inserted into the inner wall of the slot 74, and a grinding head 710 is fixedly connected to one side surface of the insert block 79.

It also facilitates the disassembly and replacement of the grinding head 710, thereby improving the efficiency of denture grinding.

[0029] Working principle: Step 1, when replacing the grinding head 710, first press the two pressing blocks 78 to drive the squeezing plate 76 to move through the driving rod 77, and the movement of the squeezing plate 76 squeezes the trapezoidal block 712, so that the trapezoidal block 712 drives the supporting spring 713 to contract, and when the trapezoidal block 712 moves to disengage from the card slot 75, the insert block 79 is pulled out of the slot 74 to complete the disassembly of the grinding head 710;

[0030] Step 2: When installing the grinding head 710, align the grinding head 710 with the slot 74 through the insert block 79, and the end of the slot 74 will squeeze the inclined surface of the trapezoidal block 712, so that the support spring 713 and the trapezoidal block 712 will shrink. When the insert block 79 is fully inserted into the socket, the elastic force of the support spring 713 drives the trapezoidal block 712 to insert into the slot 75 for limiting, and squeezes the extrusion plate 76, so that it drives the pressing block 78 to reset and move through the driving rod 77;

[0031] Step three, when in use, start the servo motor 5 to drive the rotating shaft 6 to rotate, the rotation of the rotating shaft 6 drives the annular rotating block 73 to rotate, thereby driving the grinding head 710 to rotate and grind, and at the same time, the rotation of the rotating shaft 6 drives the fan disk 7 to rotate, and the airflow generated when the fan disk 7 rotates is transported to the metal molding tube 72 through the air pipe 71, and the airflow is ejected through the metal molding tube 72, so as to clean the dust at the grinding place of the grinding head 710, and the blown dust is adsorbed by the adsorption device.
