3D printing material spraying device

Abstract

The invention relates to the field of 3D printing, in particular to a 3D printing material spraying device. The device comprises a transmission mounting cylinder arranged vertically, wherein the upperend of the transmission mounting cylinder is vertically provided with a support mounting cylinder, the outside of the support mounting cylinder is symmetrically provided with support mounting plates,fixed mounting holes run through the support mounting plates, the upper end of the support mounting cylinder is installed with a rotating cover plate through a rotating shaft set in the upper left corner, the lower end of the transmission mounting cylinder is vertically provided with a main material guide mounting cylinder at the central position, and two sets of sub guide mounting cylinders aresymmetrically arranged on the outer side of the upper half of the main material guide mounting cylinder. Through the driving of a synchronous bevel gear, the device has a high torque and stable transmission power. Through the transmission of a synchronous belt, first-stage spiral pressurized material guide and second-stage spiral pressurized material guide are combined for the material to make thedevice have a good material guiding effect, so as to guarantee the continuity of printing and spraying. At the same time, the angle of spraying is changed, so that the device can adapt to different spraying needs.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printing material spraying device. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using powdered metal, plastic, biomaterials, etc., to construct objects by layer-by-layer printing. 3D printing usually uses digital Technical material printer to achieve. [0003] In the existing 3D continuous printing process, the trajectory of the 3D printing nozzle is a straight line. When printing, the 3D printing nozzle always prints in one direction. In the process of printing with the above method, since the trajectory of the 3D printing nozzle is a straight line, the printing at the corner of the product will cause unnatural and unsmooth connection at the corner, which will affect the appearance of the product. Seriously, Even affect the quality and use of the product. [0004] Chinese patent (notificat...
