Powder recovery post-processor

Abstract

The present invention relates to a powder recovery post-processor, which comprises a shell, a powder collecting device, a dust collecting system and a dust removal system. The dust collecting system consists of a dust collecting joint, a cyclone dust collecting device, a first air draught device and a plurality of transmission tubes. The plurality of transmission pipes are sequentially connected to the dust collecting joint, the cyclone dust collecting device, the first air draught device and the powder collecting device. The dust collecting joint is arranged in an external dust collecting tube, so as to collect dust into the dust collecting system and then introduce the dust to feeding powder collecting device. The dust removal system comprises a second air draught device and a plurality of guide tubes, wherein the plurality of guide tubes are communicated with a first space, and sequentially connected to the second air draught device and the powder collecting device, so that the remaining powder suspended in the first space enters the dust removal system, and then the powder is sent to the powder collecting device.

Description

【Technical field】 [0001] The invention relates to a powder recovery post-processing machine, especially a powder recovery post-processing machine suitable for a three-dimensional forming device. 【Background technique】 [0002] Rapid Prototyping (RP technology for short) is a technology derived from the concept of building a pyramid layer by layer, which can quickly and cost-effectively shape the designer's idea in a short time and present it to the public. Its main feature is the quickness of forming, which can automatically and quickly convert any complex shape design into a 3D solid model without any tools, molds and jigs, which greatly shortens the development cycle of new products And reduce the cost of research and development, and can ensure the time to market of new products and the success rate of new product development. It promotes a more complete relationship among technical personnel, as well as between technical personnel and non-technical personnel such as ente...

Problems solved by technology

However, spraying the surface of the three-dimensional molding with a strong airflow will mix the glued powder and the recyclable powder together, resulting in the collection of the remaining powder that cannot be recycled and reused

Furthermore, the conventional post-processing machine is only used to clean the surface of three-dimensional molded objects without other corresponding expansion functions, such as cleaning and vacuuming the operating machine of the rapid prototyping device, or performing subsequent powder filtration Recycling, etc., so the use of this post-processing machine is really limited, so the cost of a single machine is relatively increased
