Problems solved by technology

The metal powder screening device for metal 3D printers passes through material boxes, slow motors, screw shafts, gears, chains, connecting pipes, coarse mesh plates, fine hole mesh plates, micro motors, cams, springs, and impurities The mutual cooperation between the tubes, although this method is convenient to sieve the metal powder, but the sieving effect of the powder sieving machine is not good, the metal powder is easy to gather in the powder sieving machine to reduce the screening efficiency, and it is inconvenient to prevent agglomeration The metal powder is crushed, and the powder sieving machine in the prior art is inconvenient to take out the unqualified metal powder

Abstract

The invention discloses a post-printing powder collecting treatment device for a basic shaft type metal 3D printer. The post-printing powder collecting treatment device comprises a powder suction device and a powder screening machine. A powder storage cylinder of the powder suction device is communicated with a sleeve of the powder screening machine through a powder feeding pipe; and a vacuum conveyor is arranged on the powder feeding pipe. The post-printing powder collecting treatment device for the basic shaft type metal 3D printer is simple in structure and convenient to use, metal powder can be recycled or metal powder at a certain position can be sucked into the powder screening machine to be screened, and temporary storage, conveying, screening, storage and the like can be further carried out.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a post-printing powder collection processing device for a shaft-type metal 3D printer. Background technique [0002] Metal 3D printing technology has the advantages of personalized design, fast forming, and short manufacturing cycle. It is very suitable for the manufacture of small batches, personalized metal parts with complex surfaces and internal structures. In the process of 3D printing metal powder, high energy density The laser directly acts on the metal powder, and the laser scans quickly to make the metal powder melt and condense quickly. [0003] Due to the high price of metal powder, it is inconvenient to remove the metal powder remaining on the surface of the product after printing and processing the product, and to recycle and reuse the recovered powder, resulting in waste and increased costs, and the powder suction device in the prior art is inconvenien...
