Problems solved by technology

However, in order to spread the powder to be formed in the forming area, a general powder supply vehicle will spread more powder to be formed in order to cover the forming area, but spreading too much powder will cause waste of the powder to be formed , reducing the utilization rate of the powder to be formed

Embodiment Construction

[0014] see figure 1 , A preferred embodiment of the powder supply device of the present invention includes a support portion 10 , a support member 200 and a powder supply vehicle 20 . In this embodiment, the supporting part 10 can be a wall of a building chamber in a 3D printer, and a forming area 800 is provided in the forming chamber of the 3D printer.

[0015] A guide part 100 is disposed on the support part 10, and the guide part 100 includes a preset track. In this embodiment, the preset track is a track parallel to the forming area 800 . The powder supply cart 20 is connected to the first end of the support member 200, and the second end of the support member 200 is slidably disposed in the guide portion 100, so that the powder supply cart 20 can move along the preset track, such as Control the powder supply vehicle 20 to move along the straight line where the track is located. In other embodiments, the track of the powder supply vehicle 20 can also be other tracks, s...

Abstract

A powder supply device, comprising a powder supply cart, the powder supply cart includes a storage space and a powder spreader arranged in the storage space, the powder spreader includes a powder supply chamber composed of several side walls and a rotating A powder feeder arranged in the powder supply chamber, the powder feeder is in contact with the side wall of the powder supply chamber to form a loading chamber for loading the powder to be molded, the powder feeder includes a contact surface in contact with the powder to be molded, Several powder spreading ports are arranged on the contact surface; when the powder feeder rotates from a first position to a second position, the powder to be molded in the powder spreading ports on the contact surface falls into a forming area. The above-mentioned powder supply device is provided with several powder spreading ports on the contact surface, so that when the first position of the powder feeder is rotated to the second position, the powder to be molded in the powder spreading port will fall into the forming area more evenly, In this way, it can avoid the waste of the powder to be molded caused by spreading too much powder, and improve the utilization rate of the powder to be molded.

Description

technical field [0001] The present invention relates to a powder supply device, in particular to a powder supply device for a 3D (three-dimensional, three-dimensional) printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of rapid prototyping technology, based on digital model files, using metal or non-metallic materials to form powder, melting / melting the laid flat powder to be formed layer by layer, and then Solidification build-up molding to construct three-dimensional solid printing equipment. A general 3D printer includes a forming cylinder. During 3D printing, after sintering a layer of powder to be formed in the forming area, a powder supply vehicle will spread the powder in the forming area to make a new layer to be formed. Sintering action of the powder. However, in order to spread the powder to be formed in the forming area, a general powder supply vehicle will spread more powder to be formed in order to cover the f...
