Ceramic material grinding and screening device for three-dimensional (3D) printing

Abstract

The invention discloses a ceramic material grinding and screening device for three-dimensional (3D) printing. The ceramic material grinding and screening device for 3D printing comprises a base, a grinding box, a grinding boat, a receiving groove and a grinding wheel, wherein the grinding box is fixedly arranged on the base through screws; at least two groups of slide rods are horizontally and fixedly arranged in the grinding box; the grinding boat is slidably arranged on the slide rods; third connecting rods are hinged to the lower sides of moving blocks; and the other ends of the third connecting rods are rotatably arranged on a rotary shaft of the grinding wheel. The ceramic material grinding and screening device for 3D printing provided by the invention is novel in structure; the grinding pressure can be adjusted through adjusting the space between the grinding wheel and a preliminary screening plate on the bottom part of the grinding boat, and the grinding pressure can be adjustedaccording to the required grinding granularity, so that a grinding effect is greatly improved; and through the up-and-down vibration of a sieve plate, the screening speed of ceramic material powder on the sieve plate is greatly improved, and meanwhile, the ceramic material powder is prevented from blocking on the surface of the sieve plate through the up-and-down vibration of the sieve plate compared with a static sieve plate.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a ceramic material grinding and screening device for 3D printing. Background technique [0002] 3D printing, also known as additive manufacturing, is a type of rapid prototyping technology and is known as the core technology of the "third industrial revolution". Compared with traditional manufacturing technology, 3D printing does not need to manufacture molds in advance, does not need to remove a large amount of material during the manufacturing process, and can obtain the final product without going through complicated forging processes. Therefore, structural optimization and material saving can be achieved in production. and save energy. 3D printing technology is suitable for new product development, rapid single-piece and small-batch parts manufacturing, complex-shaped parts manufacturing, mold design and manufacturing, etc., and is also suitable for the manufacture of diff...
