Abstract

The invention discloses a belt-type flexible stick powder spreading device, which comprises: a frame; a mounting frame arranged on the bottom side of the frame; a first roller, which is rotatably connected to the mounting frame; a second roller, which is rotatably connected On the mounting bracket, the second roller is located below the first roller, the rotation axis of the first roller is parallel to the rotation axis of the second roller; the rotation drive device, the rotation drive device The drive is connected to the first roller or the second roller; the annular scraping belt bypasses the first roller and the second roller, and is connected with the first roller and the second roller, and the outer surface of the annular scraping belt The surface is a processed surface, and the invention avoids the need to replace the entire roller device after the processed surface is scratched, improves the overall utilization efficiency, and reduces equipment manufacturing and application costs.

Description

technical field [0001] The invention relates to an additive manufacturing equipment, in particular to a belt-type flexible stick powder spreading device. Background technique [0002] Additive manufacturing, commonly known as 3D printing, is an advanced manufacturing technology developed based on the principle of layered manufacturing. Powder bed additive manufacturing is a widely researched and applied additive manufacturing process. The common powder bed additive manufacturing process There are laser selective sintering, laser selective melting, direct metal forming and electron beam selective melting. The process principle is generally as follows: the powder spreading device spreads a layer of powder on the processing chamber, and the control system makes the processing heat source selectively melt the powder according to the slicing data of each layer to obtain the shape of the layer of the formed part, and then the processing chamber descends One layer, the powder spre...
