Abstract

The present invention relates to the technical field of three-dimensional printing, and particularly discloses a mixed powder feeding device for three-dimensional printing equipment. The device comprises a molding cylinder, a moving powder cylinder, a driving assembly and a powder spreading assembly, wherein the molding cylinder is provided with a fixed powder cylinder, the moving powder cylinderis arranged on the molding cylinder, can slidably reciprocate on the molding cylinder and is located above the fixed powder cylinder, the driving assembly is used for driving the moving powder cylinder to slide, and the powder spreading assembly is arranged at the bottom of the moving powder cylinder; one side of the powder spreading assembly is provided with a powder leaking device arranged at the bottom of the moving powder cylinder and used for conveying powder in the moving powder cylinder to a molding face of the molding cylinder; the fixed powder cylinder is internally provided with a powder feeding device body used for conveying the powder in the fixed powder cylinder upward. The mixed powder feeding device for the three-dimensional printing equipment can achieve a function of alternative mixed powder spreading in two ways of moving powder spreading and fixed powder spreading, and also can achieve powder spreading of two materials, thereby being conductive to improving the powder spreading efficiency.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a mixing powder feeding device of 3D printing equipment. Background technique [0002] 3D printing (additive manufacturing), also known as rapid prototyping, is a manufacturing technique that builds three-dimensional objects by continuously fusing more than one thin layer of material. Powder bed additive manufacturing is a kind of additive manufacturing technology route. The powder laying structure of the existing metal 3D printing equipment is mainly divided into two methods: mobile powder laying and fixed powder laying, both of which have low powder laying efficiency. High, unable to realize the powder spreading function of the two materials. Contents of the invention [0003] In order to solve the above-mentioned problems in the background technology, the purpose of the present invention is to provide a mixed powder feeding device for 3D printing equipment, which can re...
