Air filtering device of 3D printer

Abstract

The invention belongs to the technical field of air processing, and provides an air filtering device of a 3D printer. The device comprises a transfer cavity and a filtering cavity, wherein filtering holes are evenly distributed in the side of the transfer cavity; a lifting device is arranged in the filtering cavity and comprises a shell, a lifting plate, a limiting rod and a pressing plate; a limiting groove and through holes corresponding to the filtering holes are formed in the shell, one side of the limiting groove is obliquely arranged, and an auxiliary rod is installed at the lower end ofthe lifting plate; the two limiting rods are symmetrically installed, the limiting rods are connected with the lifting plate through rotating shafts, the upper ends of the limiting rods are obliquelyarranged, the lower ends of the limiting rods have arc-shaped bending angles, stop rods are installed on the limiting rods, and the stop rods are sleeved with elastic pieces; and fixing blocks are arranged at the upper end of the pressing plate and matched with the arc-shaped ends of the limiting rods. Therefore, air filtering and conveying can be effectively achieved, working efficiency is improved, and filtering quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air, in particular to an air filter device for a 3D printer. Background technique [0002] Ordinary printers used in daily life can print flat objects designed by computers, and the so-called 3D printers are basically the same as ordinary printers, but the printing materials are somewhat different. The printing materials of ordinary printers are ink and paper, while 3D printers are equipped with metal Different "printing materials" such as ceramics, plastics, sand, etc. are real raw materials. After the printer is connected to the computer, the "printing materials" can be superimposed layer by layer through computer control, and finally the blueprint on the computer becomes kind. In layman's terms, a 3D printer is a device that can "print" a real 3D object, such as printing a robot, printing a toy car, printing various models, or even food. The reason why it is popularly called "printer" refers to the t...

AI Technical Summary

Problems solved by technology

During the printing process, due to the difference in raw materials, the printer will be blocked or the printing quality will be reduced, which will affect the printing effect.

[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
