Description

Technical Field

[0001] The utility model relates to the technical field of suction machines, in particular to a vacuum suction mechanism and a powder selection machine. Background Art

[0002] The Chinese patent document with the existing announcement CN217296376U discloses a vacuum suction machine, which proposes that the conveying pipe is fixed to the upper left of the separation bin. When negative pressure is formed in the bin, materials and dust will enter the bin through the conveying pipe, and the dust removal effect is not good. At the same time, the bin is fixedly connected to the left side of the cabinet. When materials are stored in the bin, the force is uneven; its solution is to indirectly drive the first stirring blade to rotate through the first motor, the first stirring blade stirs the material in the separation bin, and the fan blows the dust in the separation bin, thereby increasing the dust raising efficiency and preventing the material in the separation bin from being blocked. One end of the conveying pipe is located at the lower side of the material, which reduces the entry of dust, so that the dust and the feed are separated from each other through the material, and the use effect is better. Moreover, by fixing the roller part to the bottom plate and the support frame to the bin, the force is more uniform when the material is stored in the bin to prevent deviation. The several vents on the cabinet door increase the heat dissipation efficiency of the vacuum pump.

[0003] The above scheme and the prior art use a single-piece mesh structure to implement the powder screening structure of the vacuum suction mechanism when selecting powder. During use, the accumulation of material powder will cause unsmooth powder selection, which will reduce the production efficiency of the vacuum suction mechanism in selecting powder and increase labor costs, and cannot meet actual use requirements.
