[0026] Working principle: When the device is sintering the denture, the zirconium dioxide denture can be placed in the left discharge box 10, and then the electric push rod 21 is started to run. The block 19 can be pushed upward by the electric push rod 21, and then the block 19 can pass through the through hole 20 and be stuck in the card slot 13. At this time, the sealing plate 11 can be pushed upward by the electric push rod 21, and the discharge box 10 can be pushed into the sintering box 9 to sinter the denture. When the discharge box 10 is pushed into the sintering box 9, the sealing ring 17 can be stuck in the funnel-shaped groove. As the sealing plate 11 is continuously moved upward, the sealing ring 17 can push the spring 15 to compress. When the sealing plate 11 is stuck in the bottom of the sintering box 9, the elastic force of the spring 15 can be used to push the sealing ring 17 to fit tightly with the funnel-shaped groove, thereby improving the sealing performance of the sintering box 9 after closing to prevent heat loss. At this time, the heating tube 8 can be started to sinter the zirconium dioxide denture;

[0027] After sintering is completed, the electric push rod 21 is started again to drive the block 19 to reset. At this time, the weight of the sealing plate 11 can be used to follow the block 19 to reset, and then the motor 4 is started to run, and the gear A3 can be driven by the motor 4, and then the gear A3 drives the rotating rod 2, and the rotating rod 2 can drive the turntable 7 to rotate, so that the turntable 7 can rotate 180 degrees to swap the positions of the two groups of sealing plates 11. At this time, the fan 6 is started to run, and the fan 6 can be used to blow air to dissipate heat for the dentures in the discharge box 10, quickly reduce its temperature, and facilitate the operator to take the material. At the same time, the operator can put the dentures that need to be sintered in another group of discharge boxes 10 to ensure work efficiency.
