Raw material recycling device for 3D metal printer

Abstract

The invention discloses a raw material recycling device for a 3D metal printer. The raw material recycling device comprises a bottom plate and a printing platform, wherein the printing platform is arranged on the upper surface of the bottom plate; a material shoveling assembly is arranged on the upper surface of the bottom plate and is positioned on one side of the printing platform; the materialshoveling assembly comprises a vertical plate; a screw rod is rotationally arranged in the vertical plate; a push plate is rotationally arranged on one side of the screw rod; an electric heating wireis arranged in the push plate; a first motor is fixedly arranged on one side of the vertical plate; the first motor is in transmission connection with the screw rod; a collecting cylinder is slidablyarranged on the bottom surface of the bottom plate; a guide shaft is rotationally arranged in the collecting cylinder; a spiral sheet is arranged on the surface of the guide shaft; the outer ring of the spiral sheet is in clearance fit with the inner wall of the collecting cylinder; a material discharge opening is formed in one side of the bottom of the collecting cylinder; a sieve plate is fixedly arranged at the bottom of the material discharge opening; and one end of the guide shaft is positioned at one end of the outside of the collecting cylinder, and is fixedly connected with a third motor. Raw materials are recycled.

Description

Technical field [0001] The invention belongs to the technical field of 3D printers, and specifically relates to a raw material recovery processing device for 3D metal printers. Background technique [0002] Rapid prototyping is a leap in manufacturing technology. It proposes a brand-new mode of thinking from the principle of molding and creates a new opportunity for the development of manufacturing technology. Since the emergence of the idea of ​​material accumulation in the early 1980s, researchers have developed many rapid prototyping technologies, collectively referred to as 3D printing. Among them, laser curing molding technology is one of the important ones. [0003] The so-called laser curing molding technology is to spray a layer of powdered raw materials first, and then use the high energy of laser irradiation to solidify the powdered raw materials according to the design of the drawing, and repeat this process repeatedly, so that the powdered raw materials are solidified ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a raw material recovery and processing device for 3D metal printers to solve the problem that in the prior art in the molding process mentioned above in the background art, a part of the powdery raw materials of each layer will not be solidified, and these uncured The solidified raw materials can be recycled and reused; in addition, some debris will be produced during the post-polishing process of the 3D three-dimensional model, and at this stage, these recycling tasks are generally done manually, which is time-consuming and labor-intensive.
