The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As described in the background art, the existing device for mixing different powders has a problem of uneven mixing, so that the quality of the manufactured finished product is poor, and the main reason is that the powder falls into the bottom of the mixing chamber at the initial stage of mixing different powders, and cannot contact with the mixing mechanism, and the mixing mechanism cannot stir and mix the powders, so that the powders at the bottom of the mixing chamber cannot be mixed uniformly.

As shown in fig. 1, an embodiment of the present invention relates to a powder metallurgy mixing apparatus for mixing different powders, which includes a mixing box 100, a mixing mechanism 200, and a powder lifting mechanism 300.

The mixing box 100 is provided with a mixing chamber 101; the mixing mechanism 200 comprises a driving source 210 arranged on the mixing box 100 and a mixing component 220 in driving connection with the driving source 210, wherein the mixing component 220 is arranged in the mixing cavity 101, and the mixing component 220 is spaced from the bottom wall of the mixing cavity 101; the powder lifting mechanism 300 includes a fan 310 and an air outlet channel 340 connected to the fan 310, the air outlet channel 340 is located in the mixing chamber 101, and the air outlet channel 340 has an air outlet 341, and the air outlet 341 is configured to be opposite to the powder located at the bottom of the mixing chamber 101.

In use of the powder metallurgy mixing apparatus, the driving source 210 is used to drive the mixing assembly 220 to mix different powders placed in the mixing chamber 101. Due to gravity, some of the powder drops to the bottom of the mixing chamber 101 during the mixing of the different powders by the mixing assembly 220. In the powder metallurgy device described above, the blower 310 may be turned on to blow the powder located at the bottom of the mixing chamber 101 through the air outlet passage 341 by the blower 310, so that the powder is blown up to be again contacted with the mixing component 220, and thus, the mixing component 220 may mix the powder again, thereby improving the uniformity of mixing different powders.
