A raw material recycling system applied to metal powder printing process

Abstract

The invention proposes a raw material recovery system applied to the metal powder printing process, which includes a shell, a crushing mechanism, an air supply mechanism, a powder collection mechanism and a control module; The outlet is located below the output port, the air inlet is located at the bottom of the shell, and an intercepting net is arranged at the air inlet; the crushing mechanism includes no less than one blade, a cutter head and a connecting rod, the connecting rod is vertically installed inside the casing, and the cutter head is rotatable Installed on the lower end of the connecting rod, the blade is installed on the outer periphery of the cutterhead, and the cutterhead is connected with a second driving mechanism to drive its rotation; the air supply mechanism includes a fan and an air pipe, the fan is installed at the first end of the air pipe, and the second end of the air pipe is connected The air inlet is located under the intercepting net; the powder collection mechanism includes a powder feeding pipe and a powder collection bag, the first end of the powder feeding pipe is sealed and connected to the output port of the casing, and the powder collection bag is connected to the second end of the powder feeding pipe. The invention can recycle the workpiece printed by the metal powder.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a raw material recycling system applied to a metal powder printing process. Background technique [0002] Three-dimensional printing, also known as 3D printing (Three Dimensions Printing), belongs to a kind of rapid prototyping technology. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products, especially some high-value products (such as hip joints or teeth, or aircraft parts) have used this Parts printed by this technology. [0003] For some metal workpieces that require high precision, it is a common method to use three-dimensional printing technology to print metal powder as ra...

Problems solved by technology

[0003] For some metal workpieces that require high precision, it is a common method to use three-dimensional printing technology to print metal powder as raw material, but in the printing process, due to various reasons, unqualified products are always inevitable. The acquisition cost of some precious metal powders is high, and the appearance of substandard products also increases the cost of raw materials consumed in the production process. If they are directly consumed, it will cause great waste of raw materials
