Powder laying device for full-color powder 3D printing

Abstract

The invention discloses a powder laying device for full-color powder 3D printing. The powder laying device comprises a storage assembly for storing powder materials, a moving assembly for pushing thestorage box to move left and right, a pushing assembly for preventing material blocking and compacting the laid powder materials, and a powder laying assembly for flattening. The storage assembly comprises a storage box for storing the powder materials, two sets of feeding pipes for feeding, an electric flashboard valve for cutting off or communicating for discharging, and a guiding pipe for discharging. The moving assembly comprises a supporting frame for supporting, two sets of sliding grooves and two sets of sliding blocks for guiding and limiting, a forward-backward rotating motor for driving, and a ball screw for being connected with the storage box, and the sliding grooves and the sliding blocks are used for guiding and limiting. The pushing assembly comprises an electric push rod for providing power, a pressing block for compacting the powder materials, and a plurality of stirring rods for stirring the materials. According to the device, loosening of the powder materials and extruding after injection are easily and conveniently achieved, blocking is avoided, and the density of the powder materials in a printing slot is enhanced.

Description

technical field [0001] The invention relates to the technical field of 3D printing powder spreading, in particular to a powder spreading device for full-color powder 3D printing. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. The working principle of 3D printer is basically the same as that of ordinary printer. It is to superimpose "printing materials" layer by layer through computer control. , and finally turn the blueprint on the computer into a physical object. This technology is often used in mold manufacturing, industrial design and other fields to make models or for direct manufacturing of some products. There are many 3D printing technologies. 3D printing of junction materials, 3D printing of photocuring materials and 3D printing of molten materials. [0003] As a kind of printing, full-color 3D printing generally uses gypsum pow...

Problems solved by technology

[0004] The current powder spreading generally drives the storage box to move through the driving device, so that the lower part of the storage box is docked with the upper part of the printing tank, so that the materials inside the storage box fall into the upper part of the printing tank, and then the storage box is driven by the driving device. The material box is spread from the upper part of the printing tank by using the rollers on the side of the material storage box to complete the material spreading. However, the interior of the existing material storage box generally lacks the stirring of the material, which is prone to material jams. Conducive to use, on the other hand, the lack of extrusion of the paving material to the paving material, resulting in a relatively loose paving material, which is not conducive to subsequent printing
