Abstract

The invention discloses a feeding device and method of a ceramic 3D printing machine and the 3D printing machine. The feeding device comprises a linear movement mechanism (1) for driving a cyclic supply cylinder, the cyclic supply cylinder (2) for continuously conveying ceramic printing materials to a scraper mechanism (3), and the scraper mechanism (3) with a continuous discharge function and a simultaneous scraping function. When a movable piston cylinder body (5) moves leftwards relative to a piston (6), the ceramic printing materials in a material box (4) enter a piston cavity (7) througha first feeding hose (10) via a first one-way valve (9) and enter a first discharge hose (32) through a second one-way valve (31) to reach a junction station (11), and when the movable piston cylinderbody (5) moves rightwards relative to the piston (6), the ceramic printing materials enter the piston cavity (7) through a second feeding hose (35) via a third one-way valve (12) and enter a second discharge hose (14) through a fourth one-way valve (13) to reach the junction station (11).

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a ceramic 3D printer feeding device, a feeding method and a ceramic 3D printer. Background technique [0002] The traditional top-illuminated surface exposure 3D ceramic printer can be divided into a projection device, a scraper, a feeding device, and a Z-direction feeding (forming or printing) platform. The ceramic printing material is printed layer by layer in the Z direction (vertical direction) according to the pre-designed three-dimensional model to generate a section layer, and at the same time, it is irradiated with light waves of a specific frequency to make it quickly solidified, and each section layer is stacked and bonded. Together, the final 3D model is formed. At present, in traditional ceramic 3D printers, the ceramic printing materials are piled up on the working platform driven by the feeding device, then flattened under the action of the scraper, and finally...
