Abstract

The invention discloses a 3D printing feeding and powder spreading device. The 3D printing feeding and powder spreading device comprises a printer body. A powder spreading plate is mounted at the front end of the printer body. A stepping motor is mounted at the rear end of the printer body. The stepping motor is in threaded connection with a sliding block through a lead screw. The sliding block isclamped to the side edge of a lead screw box and a sliding groove through a first clamping groove and a second clamping groove correspondingly. A powder spreading roll is welded to the sliding blockthrough a second connecting plate. An electric cylinder is mounted on the powder spreading roll. The output end of the electric cylinder is connected with a silica gel scraping plate. Two limiting plates are welded to the rear end of the printer body through a first connecting plate. The 3D printing feeding and powder spreading device can protect the powder spreading roll in motion against damagecaused by collision. Moreover, a spring and a rubber plate can achieve the buffering function, and the silica gel scraping plate can be adjusted to rise and drop through the electric cylinder. The 3Dprinting feeding and powder spreading device is suitable for spreading different thicknesses of powder. The sliding block is provided with the multiple clamping grooves and clamped to the lead screw box and the sliding groove. Accordingly, torsion force of the powder spreading roll to the stepping motor is reduced.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing material supply powder spreading device. Background technique [0002] 3D printing technology appeared in the mid-1990s and is actually the latest rapid prototyping device utilizing technologies such as light curing and paper lamination. The working principle of it is basically the same as that of ordinary printing. The printer is filled with "printing materials" such as liquid or powder. After connecting to the computer, the "printing materials" are superimposed layer by layer through computer control, and finally the blueprint on the computer is turned into a real object. The 3D printer is equipped with different "printing materials" such as metals, ceramics, plastics, sand, etc., and these printing materials also have different forms. When the powder spreading device is needed to lay the powder. [0003] However, in the prior art, the power equi...
