Abstract

The invention discloses a powder laying device for a 3D printer. The powder laying device comprises a discharging cylinder with an opening in the lower end, wherein a conveying mechanism is mounted atthe upper end of the cylinder wall on one side of the discharging cylinder, and a storage mechanism is jointly mounted at the upper ends of the conveying mechanism and the discharging cylinder. During using, firstly, a drive motor is started to drive a rotating rod to rotate, meanwhile, powder in a storage box enters a conveying sleeve through a connecting pipe, at the moment, the rotating rod drives conveying blades to convey the powder in the conveying sleeve into the discharging cylinder, meanwhile, the rotating rod drives a fixed rod to rotate under cooperation of a first bevel gear and asecond bevel gear, the fixed rod drives a receiving plate to rotate, so that powder falls into a receiving groove in the receiving plate relatively uniformly, then the powder uniformly drops to a processing supporting plate through discharging holes, meanwhile, the fixed rod drives a flattening rod to flatten the powder, and the powder is laid relatively uniformly.

Description

Technical field [0001] The invention relates to a powder spreading device for a 3D printer, and belongs to the technical field of 3D printers. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology that uses powdered materials (powder for short) based on digital model files to construct objects by printing layer by layer. [0003] When the existing printer powder spreading device is in use, it only spreads the powder by the powder spray nozzle reciprocating back and forth at a uniform speed, and the powder spreading is easy to form accumulation on the reciprocating track, which makes the powder spreading machine not Even, it is necessary to design a powder spreading device for a 3D printer. Summary of the invention [0004] The purpose of the present invention is to provide a powder spreading device for a 3D printer in order to solve the above-mentioned problems, which solves the problem that when the existing powder spreading device...
