Moreover, the grinding process can be divided into coarse grinding and fine grinding according to the different grinding materials put in. However, it is difficult for the existing grinding device to automatically switch between coarse grinding and fine grinding processes. It is very inconvenient to manually alternate between coarse grinding and fine grinding. Moreover, it is troublesome to manually put in different grinding materials, the labor intensity is high and the work efficiency is low, and the operator is prone to fatigue.

[0066] Working principle: The denture grinding device of the present application can realize batch grinding of multiple dentures, thereby improving the work efficiency. Coarse grinding material and fine grinding material can be placed in the first storage unit (more specifically, the coarse grinding material box and the fine grinding material can be placed at intervals, so that the coarse grinding material and the fine grinding material can be alternately put into the cage portion), and automatic switching between coarse grinding and fine grinding can be achieved, thereby achieving good grinding effect. The recycling of coarse grinding material, fine grinding material and dentures can be automatically carried out, and the grinding is more efficient.

[0067] The specific polishing process is as follows:

[0068] The first step is feeding: only the first electromagnet is turned on. Since the first counterweight is attracted by the first electromagnet, the feeding port of the cage is facing upwards. The cylinder translation driving unit is started to translate the cylinder until the annular cylindrical cylinder does not block the feeding port. The first opening and closing door is opened, and the denture is fed from the upper through hole. The denture is guided to the feeding port by the upper guide unit and then enters the cage.

[0069] The second step is rough grinding: at this time, the grinding material is stored in the first material storage unit (in order to facilitate the rough grinding and fine grinding of the same batch of dentures, the rough grinding material and the fine grinding material can be placed alternately). After the denture is placed, the first opening and closing door is closed, and at this time, the equipment automatically rotates the first material storage unit (one grid rotation, the angle between the two adjacent first radial partitions is one grid), so that the rough grinding material falls into the cage; the barrel translation drive unit is started to make the barrel translate until the annular cylindrical barrel completely blocks the delivery port, and the rotary motor is started to drive the cage to rotate, and the denture and the rough grinding material rotate continuously in the cage, so that the coarse grinding material performs rough grinding on the denture;

[0070] The third step is to recover the coarse abrasive material: only turn on the second electromagnet, because the first counterweight is attracted by the second electromagnet, the delivery port is facing downward, and the barrel translation drive unit is started to translate the barrel until the first through hole is aligned with the delivery port (the second material discharge port is not aligned with the delivery port), and the coarse abrasive material falls from the filter unit at the first through hole (the filter unit can allow the abrasive material to pass but cannot allow the denture to pass) to the second storage unit;

[0071] The fourth step is fine grinding: by controlling the first and second electromagnets, the feeding port of the cage is directed upward again, and the cylinder is driven so that the cylinder does not block the feeding port; the first storage unit is driven to rotate by the first driving unit so that the next compartment containing the fine grinding material is aligned with the first feeding port, the fine grinding material enters the feeding pipe through the first feeding port and then enters the cage through the feeding port, the cylinder translation driving unit is started to translate the cylinder until the annular cylindrical cylinder completely blocks the feeding port, the rotating motor is started to drive the cage to rotate, the denture and the fine grinding material rotate continuously in the cage, so that the fine grinding material performs fine grinding on the denture;

[0072] Step 5, recovering the fine abrasive material: only turn on the second electromagnet, because the first counterweight is attracted by the second electromagnet, the delivery port is facing downward, the barrel translation driving unit is started to translate the barrel until the first through hole is aligned with the delivery port, the second driving unit is started to drive the second storage unit to rotate so that the next empty compartment is aligned with the first through hole (the second discharge port is not aligned with the delivery port), and the fine abrasive material falls into the second storage unit through the filter unit at the first through hole;

[0073] The sixth step is to recycle the dentures: only turn on the second electromagnet, with the delivery port facing downward, start the barrel translation drive unit to make the barrel translate until the second through hole is aligned with the delivery port, start the second drive unit to drive the second storage unit to rotate, so that the second discharge port is aligned with the delivery port, and the dentures in the cage are guided to the lower through hole by the lower guiding unit after passing through the delivery port, the second through hole and the second discharge port, and the dentures can be recycled by opening the second opening and closing door.

[0074] After the rough and fine grinding of the previous batch, the surface of the denture will be polished to be smoother and flatter. Then the next batch of dentures can be polished. The small amount of dentures remaining in the tube can be recycled in the next batch of grinding process.

[0075] In addition, for dentures of different qualities, only the rough grinding process or only the fine grinding process can be performed, which can be selected according to needs.

[0076] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
