3D printing head and 3D printer

Abstract

The invention relates to the technical field of 3D printers, in particular to a 3D printing head and a 3D printer, the 3D printing head comprises a shell, a mounting box fixedly connected to the top of the shell, a first air cylinder fixedly connected to the center of the inner wall of the bottom of the shell, and a first supporting rod fixedly connected to the output end of the first air cylinder. According to the 3D printing head and the 3D printer, the first motor is turned on to drive the mounting plate to horizontally move through the threaded rod, the surface of the placement table is cleaned through a scraper and a cleaning brush in the horizontal moving process of the mounting plate, and when the mounting plate moves to the end close to an extrusion block, the extrusion block is driven to rotate; waste materials are scraped to the bottom of the shell through movement of the mounting plate, and the elastic air bag is driven through movement and extrusion of the mounting plate, so that the mounting plate blows waste residues on the inner wall of the bottom of the shell into the waste material box through the air outlet pipe, compared with existing manual cleaning, time and labor are saved, and the waste residues are prevented from being accumulated in the shell.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printing head and a 3D printer. Background technique [0002] 3D printer is a technology that builds objects by layer-by-layer printing based on digital model files, using adhesive materials such as powdered metal or plastic. 3D printing is usually achieved by digital technology material printers. It is often used to make models in the fields of mold making, industrial design, etc., and then gradually used for 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 more. [0003] 3D printer, also known as 3D printer, is a cumulative manufacturing technology that manufactures three...

AI Technical Summary

Problems solved by technology

[0004] After the existing 3D printer is printed, some plastic residues will adhere to the platform after the model is formed, and the plastic residue will affect the flatness of the printing platform, which will affect the quality of the next printing. Clean up residues, while some existing printers are cleaned manually, and some of the waste after cleaning will remain inside the printing table, making cleaning more difficult
