A uniform speed air supply circulation device for metal 3D printers

Abstract

The invention discloses an average-speed air supply circulation device for a metal 3D printer, comprising a circulation box, the circulation box is equipped with a filter, the filter is connected to a first circulation pump, and the first circulation pump is connected to a first buffer box , the first buffer tank is connected to a micro air pump, a pressure gauge is installed on the first buffer tank, the first buffer tank is connected to a booster tank, the booster tank is connected to a second circulation pump, and the second circulation pump Connect the second buffer box, the second buffer box is connected to the exhaust pipe, and the air velocity meter is installed in the exhaust pipe; the present invention has a disassembly plate on the side of the filter to realize the replacement of the air filter element; there are two groups The buffer box realizes air buffering, and is equipped with a flow meter to detect the air flow rate; it is equipped with a micro air pump to realize auxiliary air supply when the air volume is low, and an air booster box is provided to pressurize the air.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a metal 3D printer uniform speed air supply circulation device. 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 For real objects, air needs to be transported inside the 3D printer during 3D printing, and in order to prevent 3D printing from being affected to a certain extent, it is necessary to transp...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a uniform-speed air supply circulation device for metal 3D printers to solve the problem that the air filter element in the prior art is not easy to disassemble and replace in the above-mentioned background technology, and the air is likely to cause intermittent impact during transportation, and it is impossible to realize uniform-speed transportation. , and when the air is lost, it cannot maintain a certain pressure and other problems
