Multi-type-powder quantitative feeding mechanism suitable for rapid prototyping equipment

Abstract

The invention relates to a multi-type-powder quantitative feeding mechanism suitable for rapid prototyping equipment, which comprises a power control part, a mounting base component and a powder discharging roller, wherein the powder discharging roller is arranged in a groove in a mounting base; the mounting base component adopts a split structure, and comprises the mounting base, the powder discharging roller, two adjusting blocks and a powder discharging hopper; the two adjusting blocks are symmetrically arranged at the lower part of the mounting base, respectively fit with the two sides of the powder discharging roller, and are symmetrically arranged along the axis of the powder discharging roller; a through passage is arranged in the powder discharging roller and along a radial cross section of the powder discharging roller; a steel ball is arranged in the passage; concave troughs are mounted at two ends of the passage; and the ball constantly hits the concave troughs, so that powder on the concave troughs can fall down smoothly. The multi-type-powder quantitative feeding mechanism suitable for rapid prototyping equipment has the advantages that the problem of uneven powder discharging of the rapid prototyping equipment can be solved; the structure is simplified, so as to facilitate processing and assembling; the phenomenon of powder bridging or powder accumulation caused by the small inlet of the hopper is avoided.

Description

technical field [0001] The invention relates to the field of powder feeding for rapid prototyping equipment, in particular to a quantitative powder feeding mechanism for various powders suitable for rapid prototyping equipment. Background technique [0002] Rapid prototyping technology is a multidisciplinary system engineering technology. In the rapid prototyping technology using powder as the forming raw material, the forming process must include the storage, supply, distribution and recycling of powder raw materials. The existing rapid prototyping equipment often has the problem of uneven powder falling, and when the hopper inlet is too small, it is easy to form powder bridging or powder accumulation. [0003] Existing rapid prototyping equipment usually uses the uniform and regular arrangement of conical blind holes on the cylindrical surface of powder dropping rollers to carry powder to carry powder, but the processing of blind conical holes on the cylindrical surface of...
