Abstract

The invention belongs to a ceramic strengthening method, and particularly relates to a feeding mechanism special for a ceramic 3D printer. The feeding mechanism comprises a feeding barrel, a printinghead and a feeding hose, and the printing head comprises a conveying motor assembly, a conveying screw, a conveying pipe, a discharging head and a connecting seat; the conveying screw is rotatably connected with the axis position of the connecting seat, the top of the connecting seat is detachably connected with the conveying motor assembly, the top of the conveying pipe is detachably connected with the connecting seat, the discharging head is detachably connected with the bottom of the conveying pipe, and a feeding port is formed in the side face of the conveying pipe; and the feeding barrelcomprises a mud pressing plate, a base, a barrel body and a top cover with an air cylinder, the top cover and the base are detachably connected with the barrel body, and the mud pressing plate is arranged in the barrel body and detachably connected with a push rod of the air cylinder. According to the technical scheme, the problems that in the prior art, a feeding mechanism is too closed and inconvenient to clean are solved, stable feeding conditions and a reliable printing basis are provided for the ceramic 3D printer, and the quality of ceramic green bodies can be ensured to the maximum extent.

Description

technical field [0001] The invention belongs to a ceramic strengthening method, in particular to a special feeding mechanism for a ceramic 3D printer. Background technique [0002] Ceramic is a traditional inorganic material, exquisite and practical, with excellent characteristics such as high strength, high hardness, high temperature resistance, low density, good chemical stability, corrosion resistance, etc. It is one of the three major solid materials, and its hard and brittle characteristics It is particularly difficult to process and shape ceramic materials. Traditional ceramic preparation processes can only produce products with simple three-dimensional shapes, and the cost is high and the cycle is long. The development of ceramic 3D printing technology has made it possible to prepare complex ceramic products. The advantages of 3D printing technology, such as simple operation, fast speed, and high precision, have injected new vitality into ceramics. Functional ceramic...
