Feeding device for small metal mold 3D printer

Abstract

The invention discloses a feeding device for a small metal mold 3D printer. The feeding device comprises a material receiving pipe, one end of the material receiving pipe is in communication with a printing material processing box, the printing material processing box is internally provided with a stirring component and an extrusion component, the stirring component includes a stirring shaft, oneend of the stirring shaft penetrates through the top of the printing material processing box and extends to the outside of the printing material processing box, the end, located at the outside of theprinting material processing box, of the stirring shaft is fixedly provided with a motor, four sets of stirring blades are arrayed on the surface of the stirring shaft at equal intervals, a lantern ring is fixedly installed between every two adjacent sets of stirring blades, a pressing plate is slidingly installed in the printing material processing box, four sets of guide rods are annularly arrayed on the upper surface of the pressing plate at equal intervals, and one set of guide rod penetrates through the top of the printing material processing box and extends to the outside of the printingmaterial processing box. The viscosity of liquid plastic substances before being led to a spray pipe nozzle is effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to a feeding device for a small metal mold 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. There are various forms of stacking thin l...
