Patent ID: 8827681

Claim:
An automatic powder recycling apparatus for use in a three-dimensional object-forming system to attract and filter powder attached on a surface of a finished product, said automatic powder recycling apparatus comprising: a housing; a plurality of isolation elements connected with said housing, wherein a sealed space is defined within said housing through said isolation elements; an air-blowing device disposed within said sealed space for removing said powder attached on said surface of said finished product; a powder filtering member disposed within said housing for dividing said sealed space into a first receptacle and a second receptacle, wherein said finished product and said air-blowing device are accommodated within said second receptacle; a recycling member accommodated within said second receptacle, and comprising a screen mesh, a connecting pipe, a transmission mechanism and a recycling tank, wherein said screen mesh is driven by said transmission mechanism to be swung; and an air-inhaling device in communication with said first receptacle for allowing said first receptacle to be in a negative pressure state, wherein when said powder on said finished product is removed by said air-blowing device and directed to said powder filtering member by said air-inhaling device, said powder is filtered and blocked by said powder filtering member, wherein when said air-inhaling device is disabled, said powder blocked by said powder filtering member naturally falls down to said screen mesh, wherein said powder passing through said screen mesh is transferred to said recycling tank through said connecting pipe.
