3D printer with spray nozzle clearing and purifying functions

Abstract

The invention relates to a 3D printer with spray nozzle clearing and purifying functions. The 3D printer comprises a main body, a material box and a pedestal, wherein a printing mechanism, a clearingmechanism and a purifying mechanism are arranged in the main body; the purifying mechanism comprises a purifying room, a swing assembly and a reciprocating assembly; the swing assembly comprises a connecting rod and two swing units; each swing unit comprises a supporting shaft, a swing rod, a suction nozzle and a sleeve; the clearing mechanism comprises a movable assembly, a supporting plate, a rotary assembly and a clearing assembly; and the rotary assembly comprises a first motor and a rotary disc. According to the 3D printer with the spray nozzle clearing and purifying functions disclosed by the invention, the clearing mechanism can realize the function of automatically clearing a printing head, and reduces working burden of people; and the purifying mechanism can purify toxic substances released by the printer, and the toxic substances are prevented from being absorbed by a human body to affect body health, so that safety of the 3D printer is improved.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a 3D printer with nozzle cleaning and purification functions. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive materials to make three-dimensional objects. At this stage, 3D printers are used to manufacture products, and the technology of constructing objects by printing layer by layer. The principle of 3D printers is to put data and raw materials into 3D printers. The machine will make the product layer by layer according to the program. [0003] After the existing 3D printers are printed, some residual raw materials will adhere to the surface of the print head, which requires artificial cleaning of the pr...

AI Technical Summary

Problems solved by technology

[0003] After the existing 3D printers are printed, some residual raw materials will adhere to the surface of the print head, which requires artificial cleaning of the print head, which reduces the efficiency of cleaning. Not only that, but the existing 3D printers do not have protective equipment, and some toxic substances released Substances are directly discharged into the air and are easily absorbed by the human body, posing a threat to human life and reducing the safety of 3D printers
