Hot melting nozzle device for alloy type 3D printer

Abstract

The invention belongs to the technical field of 3D printer application, and particularly relates to a hot melting nozzle device for an alloy type 3D printer. The hot melting nozzle device comprises a first shell, a rod feeding pipe, a pushing assembly, a hot melting assembly, a pressing assembly and a nozzle assembly; the rod feeding pipe is fixedly mounted at the top of the first shell, and one end of the rod feeding pipe penetrates into the first shell; the pushing assembly comprises a first motor, a first rotating rod, a second rotating rod, two sets of transmission gears, two sets of driven gears and a plurality of sets of pushing teeth; and the first motor is fixedly installed on the inner wall of one end of the first shell, one end of the first rotating rod is in transmission connection with the output end of the first motor through a coupler, the second rotating rod is arranged on one side of the first rotating rod in parallel, and the two sets of transmission gears are both fixedly installed on the first rotating rod. According to the hot melting nozzle device, the 3D printing quality can be improved, the pushing smoothness of raw material rods is improved, and the heat dissipation effect is enhanced.

Description

technical field [0001] The invention belongs to the technical field of 3D printer applications, and in particular relates to a hot-melt nozzle device for an alloy-type 3D printer. Background technique [0002] A 3D printer is a machine that creates real physical objects based on specialized computer files, using additive methods, hence the name "additive manufacturing". [0003] Compared with traditional manufacturing technology, 3D printing technology has several outstanding advantages: no machining or any mold is required, which greatly reduces manufacturing time and production cost; due to its layer-by-layer processing and cumulative molding characteristics, manufacturing is almost free Structural complexity is limited; the model design is very simple and can be changed at any time according to the individual needs of users. [0004] There are many printing methods of 3D printers, among which the more mature ones include stereolithography, lamination, fusion deposition m...
