Abstract

The invention discloses circulation feeding equipment with a powder recovery function. The circulation feeding equipment comprises an air powder separation device, a powder falling device, a printingmovement device and a powder spreading device. A pulse reverse blowing part is arranged in the air powder separation device. The air powder separation device is located above the powder falling device. The powder falling device and the powder spreading device are located above the printing movement device sequentially from top to bottom, and a redundant powder collection device is arranged below the printing movement device. A storage hopper is arranged below the redundant powder collection device and is used for storing powder and for collecting redundant powder. The powder and air in the storage hopper are sucked into the air powder separation device through a first air pipe, the powder is concentrated at the container bottom of the air powder separation device after separation, and thepowder falls into a holding groove of the powder falling device through discharging.

Description

technical field [0001] The invention relates to the technical field of powder supply for 3D printing, in particular to a circular feeding device with a powder recycling function. Background technique [0002] 3DP (3D Print) is a rapid prototyping method that has been commercialized in 3D printing. Its working method is as follows: firstly spread a very thin layer of powder evenly on the workbench, and the printing nozzle is bonded according to the layered pattern of the parts under the control of the computer, so that the powder is bonded into a cross-sectional shape, and the workbench is lowered after one layer is completed. One layer thick, the powder spreading mechanism spreads another layer of powder on the upper layer, and then sprays and bonds the powder according to the corresponding pattern of this layer. This process is repeated until the entire 3D model is produced. After all the bonding is completed, the excess powder is removed, and then the required parts are ...
