[0019] The technical solution of the present application, through the support frame, powder mixing barrel, servo motor, cam rod, fixed bar, temporary storage box and rubber block, can make the agglomerated particles in the alloy powder contact and collide with the temporary storage box, thereby ensuring the uniformity of alloy powder mixing, and can also make the alloy powder accumulate in the temporary storage box below the powder mixing barrel due to gravity. When the temporary storage box below rotates to the top of the powder mixing barrel, the alloy powder in the temporary storage box will fall due to its own weight, thereby forming a dust effect in the powder mixing barrel, thereby improving the uniformity of alloy powder mixing. In the process of rotation of the transmission rod, the fixed bar can be reciprocated up and down, so that the rubber block on the fixed bar can knock the top of the powder mixing barrel, and then knock the powder remaining in the temporary storage box to mix it again, thereby improving the mixing efficiency of the alloy powder.

The cam bars 22 are evenly spaced, and the cam bars 22 are arranged above the fixed strip 3, so that the fixed strip 3 can be pushed downward by the arrangement of the cam bars 22. A plurality of rubber blocks 5 are bonded to the lower end of the fixed strip 3, and the rubber blocks 5 are evenly spaced, so that the upper end of the powder mixing barrel 11 can be knocked by the arrangement of the rubber blocks 5. Both ends of the powder mixing barrel 11 are rotatably connected to the support frame 1 through bearings, and a warehouse door is arranged at the lower end of the powder mixing barrel 11, so as to ensure the stability of the powder mixing barrel 11 and facilitate the rotation of the powder mixing barrel 11.

[0025] A second pulley 23 is fixedly mounted on one side of the transmission rod 21 , and the first pulley 12 and the second pulley 23 are connected by a transmission belt 24 , so that the first pulley 12 and the second pulley 23 cooperate with each other, thereby driving the powder mixing barrel 11 to rotate.

[0026] A spring 4 is sleeved on the outer side of the straight rod 31 , and the other end of the spring 4 is fixedly connected to the lower end of the fixing bar 3 , so that the fixing bar 3 can be reset by the resilience of the spring 4 .

[0027] When mixing alloy powders, first open the door of the powder mixing barrel 11, pour the alloy powders to be mixed into the powder mixing barrel 11, and then turn on the servo motor 2, which drives the transmission rod 21 to rotate. The second pulley 23 on the transmission rod 21 cooperates with the transmission belt 24 to drive the first pulley 12 to rotate, thereby driving the powder mixing barrel 11 to rotate, so that the alloy powders in the powder mixing barrel 11 are rotated and mixed, and due to the presence of multiple temporary storage boxes 32, the agglomerated particles in the alloy powder can contact and collide with the temporary storage boxes 32, thereby ensuring the uniformity of the alloy powder mixing.
