Printing head for portable 3D printer

Abstract

The invention discloses a printing head for a portable 3D printer. The printing head comprises a moving plate vertically arranged and a horizontal installing plate, wherein the horizontal installing plate is perpendicular to the moving plate and fixedly connected to the middle lower part of the moving plate; a feeding motor and a vertical baffle are installed on the horizontal installing plate; the output shaft of the feeding motor is a first feeding shaft; a second feeding shaft is rotationally connected to the vertical baffle; the peripheral surface of the first feeding shaft contacts that of the second feeding shaft; a first annular feeding slot is formed on the first feeding shaft; a second annular feeding slot is formed on the second feeding shaft and matched with the first feeding slot to form gaps for passing through of molded raw materials; nozzles below the molded raw materials are installed on the horizontal installing plate, are perpendicular to the horizontal installing plate and pass through from the upper part of the horizontal installing plate to the lower part of the horizontal installing plate. The printing head is simple in structure and applied to the portable 3D printer without resulting in a complex system, accurate feeding and excellent 3D printing functions can be realized, and practicality is strong.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a printing head for a portable 3D printer. Background technique [0002] 3D printers belong to rapid prototyping equipment and are currently in the early stage of rapid development. People are trying to use 3D printers as widely as possible; portable 3D printers are easy to carry and can be used at any time, and have a wider range of applications; the current portable 3D printers In the research and development stage, the traditional 3D printer has a complicated print head structure, and directly using it in a portable 3D printer will cause the printer system to become complicated and weaken its portable function. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a print head for a portable 3D printer in view of the deficiencies in the prior art above, which has a simple structure, reasonable design, convenient proc...
