Title:
STIRRING DEVICE AND 3D PRINTER
Document Type and Number:
WIPO Patent Application WO/2023/207868
Kind Code:
A1
Abstract:
A stirring device and a 3D printer. The stirring device comprises at least one material bin (100) and a dust removal mechanism (200). The material bin (100) is used for accommodating raw materials; the dust removal mechanism (200) is arranged on the material bin (100); a dust removal hole is formed in the upper end surface of the material bin (100); the dust removal mechanism (200) comprises a dust removal assembly (210) and a backflow assembly (220); the dust removal assembly (210) is communicated with the interior of the material bin (100) by means of the dust removal hole to recover dust generated in the material bin (100); part of the backflow assembly (220) extends into the dust removal assembly (210); the backflow assembly (220) can intermittently blow dust in the dust removal assembly (210) back to the material bin (100) from the dust removal hole, so that dust recovered in the dust removal assembly (210) can be automatically cleaned, and there is no need to manually clean dust by an operator. The process for the backflow assembly (220) to blow the dust for removal is set to be intermittent, thereby facilitating energy conservation and emission reduction. According to the 3D printer, by means of the stirring device, dust recovered in the dust removal assembly (210) can be automatically cleaned, so that the frequency of manually cleaning dust by an operator is reduced, and the effects of energy conservation and emission reduction are improved.
