Abstract

The invention discloses a powder spreading device for a 3D printer which is convenient for replacing rollers. There is a protective shell, the front and rear sides of the protective shell are provided with powder spreading roller shafts, the drive motor is connected with the powder spreading roller shaft through a transmission mechanism, one side of the protective shell is provided with a fixed end cover, and The other side of the protective shell is provided with a movable end cover, and the inner shaft body is penetratingly connected with the transmission mechanism through the fixed end cover. In the present invention, when replacing the powder spreading roller shaft, it is only necessary to disassemble the movable end cover, remove the original powder spreading roller shaft, and fit a new powder spreading roller shaft to the outside of the inner shaft body. The replacement steps Simple and easy to operate, without professional training, the feeding channel is a gradually shrinking structure, the material is uniform, and it is easy to control the powder output.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a powder spreading device for 3D printers which is convenient for replacing rollers. Background technique [0002] 3D printing is usually achieved using digital technology material printers. It is often used to manufacture models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. [0003] At present, the powder spreading rollers in 3D printers are prone to wear and tear during repeated use, which affects the quality of powder spreading, and the existing powder spreading rollers are not easy to replace. Therefore, we propose a 3D printer powder spreading device that is easy to replace the rollers to solve the above problems Existing problems. Contents of the invention [0004] The purpose of the present invention is to provide a 3D printer powder spreading device that is easy to replace the rollers, ...
