Meal mixer capable of rotating meal barrel in three-dimensional way

Abstract

The invention discloses a meal mixer capable of rotating a meal barrel in a three-dimensional way. According to the key point of the technical scheme, the meal mixer comprises a base and a rolling frame which can obliquely fix a sealed meal barrel so as to rotate the meal barrel in a three-dimensional way; the base is respectively provided with a driving motor, a gear box connected with the driving motor and a first rotating shaft connected with the gear box; a second rotating shaft is arranged at the other end of the base, and the rolling frame is rotatably arranged on the first rotating shaft and the second rotating shaft. By virtue of the three-dimensional rotating meal barrel of the meal mixer, new and old powder in a stainless steel meal barrel can be fully mixed without dead angles, so as to prevent the phenomena that the strength of formed parts is poor and the surface is rough, and avoid powder flying.

Description

【Technical field】 [0001] The invention belongs to the technical field of rapid prototyping 3D printing, in particular to a powder mixer capable of three-dimensionally rotating a powder bucket. 【Background technique】 [0002] 3D printers can be realized through a variety of technologies, and the most widely used in industrialization is the laser powder sintering technology SLS. The SLS method uses an infrared laser as the energy source, and most of the modeling materials used are powder materials. During processing, the powder is first preheated to a temperature slightly lower than its melting point, and then the powder is paved under the action of the powder scraping mechanism; the laser beam is selectively sintered according to the information of the layered section under computer control, and one layer is completed. Then proceed to the next layer of sintering, remove the excess powder after all sintering, and then you can get a sintered part. [0003] The old powder left...

AI Technical Summary

Problems solved by technology

[0004] First, when stirring and mixing, the powder container cannot be completely sealed, which will easily cause dust to fly, and the powder is usually expensive and toxic, which will cause waste and be harmful to human health;

[0005] Second, the old and new powders cannot be fully mixed during the process of stirring and mixing powders, especially in the dead corner of the container, which will make the strength of the molded parts deteriorate and the surface will be very rough;
