Problems solved by technology

In the previously applied 3D printer with a gradient powder supply system (CN109047765A), a gradient powder supply system that can realize continuous gradient changes in the horizontal section of the material is introduced. The gradient powder supply system uses a rotary mixing device. The device needs to be driven by a special motor or drive element, which is complicated and takes up a large space, and the design and layout are inconvenient. We strive to find a simple mixing device that can meet the requirements of the mixing function.

Embodiment Construction

[0019] refer to figure 2 As shown, this figure shows the schematic diagram of the embodiment of the gradient powder supply and mixing device of the present invention. The gradient powder supply and mixing device is equipped with a fixed blanking trough 72, and in the blanking trough, cylindrical thin The long spacer column 73 in the blanking trough allows the powder to fall from top to bottom through the labyrinth path of the gap between the columns in each layer, so that the powder A and powder B can be mixed, and the Y in the blanking trough In the axial direction, there are multiple inner partitions in the blanking chute installed evenly and equidistantly. When the inner partitions fall through the labyrinth path of the gap between the inner columns, the mixing in the X-axis direction is realized, which prevents the material from moving in the Y-axis direction.

[0020] What has been described above are only preferred embodiments of the present invention. It should be po...

Abstract

Disclosed is a gradient powder supplying and mixing device. By means of the mixing device, multiple layers of inner partition columns are arranged in a blanking groove in a staggered manner, so that powder passes through gaps among the inner partition columns from top to bottom to form a labyrinth path, the powder is mixed under the conditions of no power input and no rotary stirring, and by mounting blanking groove inner partition plates in the blanking groove, the axial (Y-axis direction) mixing movement of the material can be prevented.

Description

technical field [0001] The invention relates to a gradient powder feeding and mixing device, which belongs to the field of additive manufacturing. Background technique [0002] Gradient materials refer to two or more materials with different properties, which are formed by changing the composition and structure of these materials to make them change gradually or suddenly without interface. Using 3D printing methods, gradient materials and many other materials can be produced. In the experimental research of material sintering processing, in the process of gradient material 3D printing test, two or more materials need to be uniformly mixed according to the ratio, and the uniformly mixed materials are evenly spread on the upper surface of the molding cylinder by the powder spreading trolley , and then sintered by laser. In the previously applied 3D printer with a gradient powder supply system (CN109047765A), a gradient powder supply system that can realize continuous gradient...
