Problems solved by technology

[0002] In metal 3D printing equipment, after each layer of powder is sintered by the laser, it is necessary to use the powder scraping gas to recover the excess powder. After the printing task is completed, the excess powder also needs to be recovered. At the same time, the front pipe and the rear wall pipe in the metal 3D printing equipment are collected. However, in the metal 3D printing equipment, the powder collected inside the equipment can only be taken out by opening the door. Therefore, the metal 3D printing equipment needs to be stopped before opening the door. This leads to a reduction in the work efficiency of metal 3D printing equipment

Abstract

The invention relates to the technical field of 3D printing equipment, in particular to a powder recycling pipe device of metal 3D printing equipment. The powder recycling pipe device comprises a 3D printing equipment shell and a working table located inside the shell. Multiple support legs are mounted at the bottom of the shell. An opening is formed in the upper surface of the working table, and steel wire mesh is arranged inside the opening. A second housing body is arranged at the bottom of the working table and corresponds to the opening in position. An electric fan is arranged inside the second housing body. A first housing body is arranged at the bottom of the second housing body, wherein the first housing body is mounted in a manner that the first housing body is matched with the second housing body. A pipe is arranged at the bottom of the first housing body in a penetrating manner, and the bottom end of the pipe penetrates the bottom of the shell and extends to the position below the shell. A powder barrel is arranged below the shell, wherein the powder barrel corresponds to the pipe in position. The powder recycling pipe device is simple in structure and convenient to use; and powder can be collected conveniently, and in addition, the powder barrel can be demounted and mounted and taken out by a worker conveniently.
