Problems solved by technology

[0003] The existing screw-type 3D printing head usually only has one screw during use, so when the screw fails, the printing head needs to be disassembled and repaired before continuing to print. Meet the needs of users, and due to the single structure, the inner wall of the print head cannot be cleaned regularly, which reduces the applicability of the screw-type 3D print head

Abstract

The novel screw type rapid 3D printing head comprises a nozzle, a material box is welded to the top end of the nozzle, conveying cylinders communicate with the two sides of the bottom of the material box, servo motors are connected to the bottoms of the conveying cylinders through bolts, and rotating shafts of the servo motors penetrate into inner cavities of the conveying cylinders and are fixedly connected with driving rods; conveying blades are welded to the surface of the driving rod. The 3D printer has the beneficial effects that through cooperation of the nozzle, the material box, the conveying barrels, the servo motor, a driving rod, conveying blades, a feeding pipe, an electromagnetic valve, a cleaning mechanism and a controller, the 3D printer has the advantages that discharging is efficient and uniform, and the inner wall of the printing head can be cleaned regularly; and normal material conveying of the other material conveying barrel is not influenced, so that overall work is avoided, sudden pause in the printing process is not needed, and the printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a novel screw-type fast 3D printing head. Background technique [0002] 3D printing is usually realized by using digital technology material printers. It is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacturing of some products. There are already parts printed using this technology. , the technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields. [0003] The existing screw-type 3D printing head usually only has one screw during use, so when the screw fails, the printing head needs to be disassembled and repaired before continuing to print. It meets the needs of users, and due to the sing...
