Description

Technical Field

[0001] The utility model relates to the technical field of artificial teeth processing, in particular to an artificial teeth grinding and polishing device. Background Art

[0002] As people age or suffer accidental collisions, their teeth may fall out and they need to have new dentures to meet normal chewing needs. Dentures are commonly called "false teeth". There are two types of dentures: removable and fixed. Before using dentures, in order to ensure their quality and appearance during use, they usually need to be polished.

[0003] In the prior art, the utility model with publication number CN215700469U discloses a grinding device for denture production, wherein a receiving groove is protrudingly provided at the lower end of the front end wall of the shell, and the dust collecting box is detachably embedded in the receiving groove, and the two ends of the transparent protective cover are detachably fixedly connected to the upper end wall of the front end of the shell and the front end wall of the receiving groove respectively, and the denture to be polished is grasped by hand or by tweezers, and inserted from both sides of the transparent protective cover, and the outer surface of the denture is polished by contacting the surface of the denture with the grinding head, and the transparent protective cover can effectively prevent the debris generated during the denture polishing process from flying to the operator to cause physical injury, and can conveniently recycle and process the dust particles, effectively preventing the dust particles from splashing and spreading to the surrounding environment to cause pollution; however, during the polishing process, since the protective cover is a semi-open structure, the dust generated during the polishing process cannot be well isolated and collected, and at the same time, the device still needs to be transferred to other polishing devices for polishing after the polishing is completed, and the process is relatively cumbersome, resulting in relatively low processing efficiency of the denture.

Through the joint action of the base 1 and the sub-beam 3, the grinding and polishing mechanism 4 fixed on the base 1 and the sub-beam 3 always maintains stable operation during the working process.

[0032] Specifically, the grinding and polishing mechanism 4 is installed on the base 1 and the sub-beam 3, and passes through the top surface of the working chamber 2. The grinding and polishing mechanism 4 includes a motor mounting seat 41, a driving motor 42 fixed to the motor mounting seat 41, a rotating mechanism 43 fixed on the sub-beam 3, a transmission shaft 44 sleeved on the rotating mechanism 43, a plurality of fan blades 45 arranged on the transmission shaft 44, a polishing ball 47 located at the bottom of the transmission shaft 44, and a grinding sheet 46 located between the polishing ball 47 and the fan blade 45; the driving motor 42 drives the transmission shaft 44 to rotate, so that the fan blade 45, the grinding sheet 46 and the polishing ball 47 can rotate coaxially; when the driving motor 42 drives the fan blade 45 on the transmission shaft 44 to rotate, the ventilation port 21 on the top surface of the working chamber 2 is in a negative pressure state, causing the ventilation port 21 to inhale a large amount of air, which is quickly discharged downward through the fan blade 45, and the dust generated by the grinding and polishing of the denture is directly brought into the dust removal mechanism.

[0033] Specifically, the dust removal mechanism 5 is installed at the bottom of the base 1 and is directly below the grinding and polishing mechanism 5, and at the same time passes through the bottom surface of the working chamber 2. The dust removal mechanism 5 includes a dust suction port 51 at the top, a casing 52 connected to the dust suction port 51, a detachable dust box 53 arranged inside the casing 52, a knob cover 54 located below the dust box 53, a fan 55 connected through the casing 52, and an air outlet 56 below the fan 55; the dust suction port 51 is trumpet-shaped in shape, the casing 52 is fixed to the side of the base 1 to form an integral air intake cavity, the knob cover 54 can be rotated for removal, and the bottom projection area of ​​the knob cover 54 is larger than the bottom projection area of ​​the dust box 53, so that the dust box 53 can be taken out from the knob cover 54 position to clean the dust, and the inner wall of the dust box 53 is a filter structure.

[0034] Specifically, the power supply 6 is fixed on one side of the base 1, and a power protection shell 61 outside the power supply 6 is fixed to the side wall of the base 1 by fasteners.

[0035] Specifically, the legs 7 are arranged at the bottom of the base 1 to provide support for the entire device.

[0036] The working principle of the utility model is:

[0037] S1. When the utility model is used, the switch 62 on the power supply 6 is turned on, and the driving motor 4 and the fan 55 start working after being powered on. The transmission shaft 44 drives the fan blades 45 to rotate, so that the ventilation port 21 on the top surface of the working chamber 2 is in a negative pressure state, causing the ventilation port 21 to inhale a large amount of air, which is pushed by the fan blades 45 and quickly discharged downward. At the same time, the fan 55 rotates after being powered on, so that the inside of the casing 52 is in a negative pressure state, and the dust suction port 51 will accelerate the absorption of air.

[0038] S2. The artificially clamped denture is extended into the working chamber 2 from the operation port 22, and the denture to be processed is moved to the corresponding position, and is ground and polished according to the process. At this time, the dust generated by the grinding and polishing of the denture is directly brought into the dust suction port 51 by the fast-flowing air, and combined with the semi-closed working chamber 2 design, dust is prevented from flying during denture processing, thereby protecting human health. On the other hand, through the integrated grinding and polishing drive mechanism, the scope of application of the device is increased, and the grinding accuracy and efficiency of the denture are improved.

[0039] S3. The air mixed with dust is filtered by the filter on the inner wall of the dust box 53, and the dust is collected in the dust box 53. The filtered air is discharged from the air outlet 56 through the fan 55. After the grinding is completed, the dust box 53 can be removed and cleaned by simply turning the knob cover 54. The operation is simple and convenient to clean.
