Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 Embodiment 1 of this utility model provides an automatic feeding and pressing mechanism for powder, including a feeding hopper 1, a feeding box 2, a feeding box translation drive device 3, a powder mixing device 4, a feeding base plate 5, a pressing bracket 6, a pressing lifting drive device 7, and a pressing plate 8, etc. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0025] The feeding box 2 can be configured as a square box with openings at the top and bottom. The feeding box translation drive device 3 is fixedly installed on the feeding base plate 5 and is connected to the feeding box 2. The feeding box translation drive device 3 can drive the feeding box 2 to move back and forth on the feeding base plate 5. Preferably, the feeding box translation drive device 3 can be configured as a horizontally arranged cylinder.

[0026] like Figure 1 and Figure 2 As shown, the powder mixing device 4 is fixedly installed on the rear side of the pressing bracket 6, the feeding hopper 1 is used to store powder, and the bottom outlet of the feeding hopper 1 is connected to the top inlet of the powder mixing device 4.

[0027] like Figure 3 and Figure 4 As shown, the powder mixing device 4 may include a mixing tank 41, a mixing motor 42, and a mixing paddle 43.
