Abstract

The invention discloses a feeding system of 3D printing equipment. The feeding system comprises a material tank, wherein a rotating shaft is arranged in the material tank; stirring paddles are arranged on the rotating shaft; a discharging opening is formed in the bottom of the material tank, and is connected with a nozzle; an unloading channel is arranged in the nozzle; the rotating shaft is a hollow pipe; a center shaft is arranged in the rotating shaft in a penetrating manner; the length of the center shaft is greater than that of the rotating shaft; spiral blades are arranged at the bottomof the center shaft; the part, with the spiral blades, of the center shaft, penetrates through the unloading channel of the nozzle; a driving device I and a driving device II are arranged at the top end of the material tank; the driving device I is in transmission connection with the rotating shaft; and the driving device II is in transmission connection with the center shaft. The feeding system disclosed by the invention is simple in structure, and the blocking of the nozzle can be effectively avoided.

Description

Technical field [0001] The patent of the invention relates to the field of 3D printing, in particular to a feeding system of a 3D printing device. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a kind of accumulative manufacturing technology, that is, a kind of machine of rapid prototyping technology. It is based on a digital model file and can be bonded with special wax materials, powdered metals or plastics. Materials, by printing layers of adhesive materials to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The technique 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 procedure. The nozzle for 3D printer is one of the parts of 3D printer. At present, nozzles used in 3D printers have the problem of easy clogging. Summary of th...
