Powder printer and powder material molding method

Abstract

The invention discloses a powder printer and a powder material molding method. The powder printer comprises a frame, a material bin, a printing platform, a first driving component, a sliding component, a second driving component, a powder spreading roller, a third driving component, a printer and a fourth driving component, wherein an operating platform is arranged on the frame; a blanking platform and a hollow part are arranged on the operating platform; the material bin is fixed on the frame and positioned above the blanking platform; a blanking opening is formed in the lower part of the material bin; the printing platform is embedded into the hollow part; the first driving component is used for driving the printing platform to move in the height direction of the frame; the second driving component is used for driving the sliding component; the powder spreading roller is pivotally connected onto the sliding component; the third driving component is used for driving the powder spreading roller to rotate; the printer is mounted on the sliding component and positioned on the front side of the powder spreading roller; the fourth driving component is used for driving the printer to slide in the width direction of the frame. According to the invention, the stereoscopic formation of workpieces can be implemented, the precision of workpieces can be controlled accurately, the simulation degree of workpieces is improved, besides, the structure of the printer is simplified, and the printing efficiency of workpieces is improved.

Description

technical field [0001] The invention relates to the technical field of powder printing, in particular to a powder printer and a powder material forming method. Background technique [0002] Powder printing is a new type of workpiece forming process. Specifically, powder printing consumables are fixed together in a bonded form using the principle of printing and forming. Compared with traditional mold forming technology, powder printing equipment has low equipment cost. , The high degree of simulation of printed and formed workpieces, etc. Therefore, in the processing of some handicrafts, powder printing technology has been widely used. [0003] At present, when the powder printer is working, the 3D model of the workpiece is first divided into several layers according to a predetermined direction, and each layer forms a pattern with an outer contour, and then the powder in the silo is laid on the printing area layer by layer. After the powder layer is finished, use the print...

Problems solved by technology

[0003] At present, when the powder printer is working, the 3D model of the workpiece is first divided into several layers according to a predetermined direction, and each layer forms a pattern with an outer contour, and then the powder in the silo is laid on the printing area layer by layer. After the powder layer is finished, use the printer to print glue on the powder layer according to the pattern corresponding to the layer, repeat such steps, and finally complete the molding of the workpiece; the current powder printers often require printing glue when completing the above actions The printer can move up and down to achieve powder coating and printing of different corresponding layers, which makes the structure of the powder printer more complicated, the accuracy of the workpiece is difficult to control, and the printing speed is low
