Abstract

The present application relates to the technical field of the 3D printing powder preparation device, in particular to a sampling device and method used in the powder preparation process, wherein the sampling device includes a rotating disk arranged in the atomization tank, and It includes a sampling groove, the sampling groove is movably arranged in the atomization tank body along the radial direction of the atomization tank body, one end of the sampling tank body is located under the rotating disk, and the side wall of the atomization tank body An installation hole is opened on the top, and the other end of the sampling tank is erected on the side wall of the atomization tank through the installation hole, and the sampling tank includes at least two powder collecting chambers arranged along the direction of its own extension. The application realizes the purpose of classifying and collecting the powder according to particle size in real time during the atomization process through the provided sampling tank. The overall process is simple and fast, which is conducive to ensuring the efficiency of the sampling process.

Description

technical field [0001] The present application relates to the technical field of 3D printing powder preparation devices, and in particular, to a sampling device and method used in the powder preparation process. Background technique [0002] The printing materials of ordinary printers are ink and paper, while 3D printers contain different "printing materials" such as metal, ceramic, plastic, sand, etc. At present, metal powders for 3D printing are mainly prepared by the rotating disc centrifugal atomization method. The rotating disc centrifugal atomization method is to flow the molten metal droplets to the center of the high-speed rotating disc through the current-limiting export device. A layer of metal solution film is formed. Under the action of inertia and centrifugal force, the metal solution film reaches the edge of the rotating disc and is thrown out, and the droplets spheroidize and solidify during the flight to obtain powder. [0003] After the metal powder for 3D ...
