3d printing equipment

Abstract

The invention provides a 3D printing device, comprising a material storage device, a conveying device and an extrusion device connected in sequence; the material storage device includes a material storage barrel, a lifting mechanism, an extrusion structure and an adjustment mechanism; an inlet is formed on the top of the material storage barrel , an outlet is formed at the bottom, and the outlet is connected to the conveying device; the lifting mechanism has a lifting end that can enter and exit the storage barrel from the inlet; the extrusion structure is set at the lifting end, and the edge of the extrusion structure is slidingly attached to the inner wall of the storage barrel, so as to An extrusion space is formed between the extrusion structure and the material storage barrel, the extrusion space is located below the extrusion structure, and the extrusion structure is provided with a first air hole communicating with the extrusion space; the adjustment mechanism is arranged in the extrusion structure, and the adjustment mechanism It has a first state in which the first air hole is sealed, and a second state in which the first air hole is opened. The 3D printing equipment provided by the present invention can ensure the continuous supply of materials during the printing process, avoid printing interruption, and will not cause the backflow of raw materials.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing device. Background technique [0002] With the development of 3D printing technology, the range of materials that can be used for 3D printing is getting wider and wider, and clay material is one of them. The feeding process of the existing 3D printing device for clay is very cumbersome, and the feeding process takes a long time, so that the raw materials of the clay cannot be replenished quickly, which will eventually lead to a shortage of raw materials and continuous printing. During the feeding process, the action of the piston in the barrel can easily cause the backflow of the clay raw material in the subsequent equipment, which has a further negative impact on the continuity and reliability of printing. SUMMARY OF THE INVENTION [0003] The embodiment of the present invention provides a 3D printing device, which aims to simplify the feeding pr...
