Full-color powder 3D printing trough driving device

Abstract

The invention discloses a full-color powder 3D printing trough driving device which comprises a driving assembly, a powder spreading assembly, a beating assembly and a powder receiving assembly, wherein the driving assembly comprises a supporting seat, two groups of linear sliding rails, a forward and reverse rotating motor, two groups of sliding grooves, two groups of sliding blocks and a ball screw; the powder spreading assembly comprises a supporting rod, a rectangular shell and a powder holding box; the beating assembly comprises an electric push rod, a guide column, a stopper block, a spring, a sleeve, a plurality of flexible rubber columns and a plurality of rubber beating hammers; and the powder receiving assembly comprises a powder receiving box and a powder discharging plate. Theprinting trough is driven by the driving assembly to horizontally move and vertically move, so that the printing trough is convenient to be connected with the lower part of a material guide pipe and to be adjusted in height. The powder spreading assembly is used for introducing powder into the rectangular shell and achieving strickling in the moving process of the rectangular shell. Through the beating assembly, beating is carried out in the material injection process, so that the powder is more compact and the hollowing part is avoided. The powder is received through the powder receiving assembly.

Description

technical field [0001] The invention relates to the technical field of printing tank driving, in particular to a full-color powder 3D printing tank driving device. 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 a 3D printer is basically the same as that of an ordinary printer. It is to superimpose "printing materials" layer by layer through computer control, and finally turn the blueprint on the computer into a real object. This technology is often used in mold manufacturing, industrial design and other fields. It is used to make models or for the direct manufacture of some products. There are currently many 3D printing technologies. Commonly used technologies include 3D printing of bonding materials, 3D printing of light curing and 3D printing of molten materials. [0003] As a kind of printing, full-color 3D p...

Problems solved by technology

[0004] As an important step, the driving of the printing tank needs to be continuously lowered with the increase of the number of printing layers. At present, electric push rods or electric cylinders are generally used to realize its lifting. However, due to the lack of vibration during the descending process, This will easily lead to the formation of an empty drum between the material and the printing tank during the descending process of the printing tank, which is not conducive to the subsequent printing.
