Description

Technical Field

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

[0002] Dentures are what people often call "false teeth", just like "false legs" and "false limbs" are called "artificial limbs". "Dentures" mean teeth that fulfill their "duties" for humans. In medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth. Dentures are divided into removable and fixed.

[0003] During the production process of dentures, a denture cutting machine is needed to cut off the excess parts. When installing the cutting blade of the existing denture cutting machine, two pressure plates are generally set at both ends of the cutting blade, and nuts threadedly connected to the drive shaft are set at the ends of the two pressure plates away from the cutting blade. The cutting blade is then pressed between the pressure plates by the nuts abutting against the pressure plates.

[0004] However, after the cutting disc is used for a long time, the bolts will be firmly connected to the drive shaft, and when the bolts are unscrewed, the bolts will rotate with the drive shaft, which makes it inconvenient to quickly remove the cutting disc, affecting the use of the cutting machine.
