High-precision ink pressure control device for 3D additive printer

Abstract

The invention discloses a high-precision ink pressure control device for a three-dimensional additive printer. The high-precision ink pressure control device comprises an ink tank and a box body; an inner cavity of the box body is provided with a cylinder body; a cylinder sleeve is embedded in the cylinder body and is slidably connected with a piston; the piston is hinged with a shaft neck of a crankshaft by a connecting rod; the crankshaft is fixedly connected with a first rotating shaft which is horizontal; the first rotating shaft is provided with a second belt wheel; a chamber is formed atthe bottoms of the cylinder body and the box body; the side wall of the box body is provided with a first one-way valve communicated with the chamber; the side wall of the box body is provided with apressure regulating mechanism by a bracket; the pressure regulating mechanism comprises a barrel body; an inner cavity of the barrel body is provided with a bearing; an inner ring of the bearing is provided with a disk; the center of the disk is provided with a second rotating shaft; an a radial rectangular groove is formed in the disk. The ink pressure is balanced by changing the size of a gap between a slide block and the rectangular groove, so that the ink pressure can be effectively controlled to be stable, and the jet printing effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a high-precision ink pressure control device for a three-dimensional additive printer. Background technique [0002] Three-dimensional printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually realized by 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. There are already parts printed using this technology. Components, after 3D printing, need to inkjet and color the printed product. In the process of inkjet, the ink pressure needs to maintain a certain stability, and the amount of inkjet required by different parts is different. The current 3D augme...

3D printing is usually realized by 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. There are already parts printed using this technology. Components, after 3D printing, need to inkjet and color the printed product. In the process of inkjet, the ink pressure needs to maintain a certain stability, and different parts require different amounts of inkjet. The current 3D augmentation For material printers, the amount of ink ejection is mainly adjusted by adjusting the power of the ink pump, but the ink pressure changes with the change of ink ejection amount, which is difficult to control
