Abstract

The invention provides a powder spreading device and relates to the field of three-dimensional printing, comprising: a connecting assembly, a scraper holder, a positioning bolt and a scraper. a firstpositioning hole is formed in the connecting assembly; a second positioning hole is formed in the scraper holder; the positioning bolt passes through the first positioning hole and the second positioning hole to fix the connecting assembly on the scraper holder in a detachable manner. The scraper is fixed on the connecting assembly and faces a powder spreading surface. The powder spreading devicehas simple adjustment operation and short adjustment time.

Description

technical field [0001] The invention relates to the field of three-dimensional printing, in particular to a powder spreading device. Background technique [0002] The powder-spreading 3D printer is suitable for the manufacture of various non-standard parts due to its high processing precision and flexible processing shape. Among them, the powder-spreading device is an important part of the powder-spreading printer, which is used to push the metal powder to the powder-spreading surface It has a great influence on the printing accuracy. [0003] The existing powder spreading device includes a scraper, the parallelism between the scraper and the powder spreading surface is obtained by measuring the distance between multiple points on the scraper and the powder spreading surface, and then the powder spreading device is adjusted so that the scraper is parallel to the powder spreading surface, This kind of powder spreading device generally has disadvantages such as complicated ad...
