Description

Carving mills quick-witted dust keeper

Technical Field

The utility model relates to a carving mills dustproof technical field of machine, concretely relates to carving mills quick-witted dust keeper.

Background

The denture engraving and milling machine mainly processes the zirconia as a denture material, and because the rotating speed of a main shaft in the high-speed processing process reaches 20000-30000 rpm, a large amount of dust is generated in the processing process, and the main shaft can blow air in the processing process, so that the dust can scatter everywhere. Because the artificial tooth engraving and milling machine is equipment integrating mechanical, electronic, pneumatic and other components, once the raised dust is adsorbed into the screw rod, the guide rail and the electrical component, the service life of the components and the stability of the whole equipment are greatly influenced, so that the dust prevention of the artificial tooth engraving and milling machine is particularly important, and the quality of a product is directly influenced by the dust prevention effect.

Most carving mills machine in the market at present adopts the protection casing of flexible organ formula protection casing, armour formula dust cover, roll up curtain formula protection casing, the telescopic protection casing of steel isotructure mode, and these protection casings all have certain gap in the installation use, and sealed effect is not fine, and the raise dust that produces in the artificial tooth carving mills machine processes drops to lead screw, guide rail and electric elements in through these gaps. Therefore, the common dustproof mode cannot meet the requirement of processing the zirconia material by the denture engraving and milling machine. Moreover, the existing dust cover cannot meet the requirement that the drill bit of the engraving and milling machine rotates in any direction, so that the drill bit cannot operate at any position.
