Automatic conveying device for 3D printer powder material

Abstract

The invention discloses an automatic conveying device and method for a 3D printer powder material. The automatic conveying device comprises a powder material distributor, an adjusting device, a flow guiding channel and a printing carrier; a material cavity of the powder material distributor is a distributing groove of a circular truncated cone structure; the diameter of the upper bottom face of the distributing groove and the diameter of the lower bottom face of the distributing groove tend to be progressively decreased; the adjusting device is arranged at the position of an inlet of the top end of the distributing groove; an adjustable sealing piece is arranged at the position of a hole opening of the bottom end of the distributing groove and connected with a stopping bolt; the upper portion of the stopping bolt is connected with an adjusting rod; a vibrator is installed on the side wall of the bottom end of the distributing groove; the hole opening of the distributing groove communicates with the flow guiding channel; the position of an outlet of the flow guiding channel right faces the printing carrier; and a weighing device is installed at the bottom of the printing carrier and connected with a controller. The automatic conveying device is reasonable in structure, the powder material weight is calculated in advance according to the exterior and a micro structure of a model, quantitative automatic powder laying of the powder raw material is achieved, the work efficiency is high, the powder laying is uniform, the requirement for the powder scraping process of a scraper is not high, and the cost investment is low.

Description

technical field [0001] The present invention relates to the technical field of scraper devices for 3D printer powder spreading, in particular to a 3D printer powder material automatic transmission device and method Background technique [0002] 3D printing has brought about a worldwide manufacturing revolution, which makes companies no longer consider the production process when producing parts. Any complex shape design can be realized by 3D printers. 3D printing can be directly processed from Objects of any shape are generated from computer graphics data, which greatly shortens the production cycle of products and improves productivity. 3D printing technology is bound to become one of the many breakthrough technologies in the future manufacturing industry. [0003] 3D printer is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bonda...

Problems solved by technology

However, in the actual operation process, there are mainly the following disadvantages: 1. The powder material is not quantitative, and more powder is generated; 2. The powder material is not evenly laid during the powder spreading process, and the thickness that needs to be laid is relatively large; 3. The scraper is scraped Powder process requires high
