Problems solved by technology
[0003] Among them, the electrostatic adsorption powder spreader is used for small particles of pure metal powder, and can only spread powder with a thickness of less than 0.3mm. When the thickness is too high, its electrostatic adsorption effect will become poor, and the upper layer of powder will fall off easily.
The single-stage powder spreader, although it can spread thick powder, is only suitable for dusting coarse-grained powder below 150 mesh, and its accuracy is poor.

The powder spreading machine is suitable for spreading powder.
Description
technical field [0001] The invention relates to a device for spreading fine metal powder on metal or other flat plates, in particular to a powder spreader. Background technique [0002] The powder spreader is a device that spreads fine metal powder on a metal plate to prepare for the next step (such as sintering or other processing). At present, the powder spreader is generally divided into two types: electrostatic adsorption powder spreader and single-stage powder spreader. kind. [0003] Among them, the electrostatic adsorption powder spreader is used for small particles of pure metal powder, and can only spread powder with a thickness of less than 0.3mm. When the thickness is too high, its electrostatic adsorption effect will become poor, and the upper layer of powder will easily fall off. And the single-stage powder spreader, although it can carry out the spread powder of thick powder, it is only suitable for the powder spread of the coarse particle powder below 150 ord...
