[0028] For example Figure 1And Figure 2 As shown in the figure, the present application provides a powder mixing device, which comprises a box body 1, a first feeding hopper 2 and a second feeding hopper 3 are symmetrically arranged on the top of the box body 1, a blowing assembly 4 and a stirring assembly 5 are arranged in the box body 1, a driving motor 6 is arranged at the bottom of the box body 1 for driving the stirring assembly 5 to rotate, a discharge port 7 is arranged at the lower part of one side of the box body 1, the blowing assembly 4 comprises a group of blowing boxes 41 which are symmetrically arranged on two sides and are inclined, and high-pressure gas pipes 42 which are connected with the blowing boxes 41 respectively, the high-pressure gas pipes 42 extend to the outside of the box body 1 away from the blowing boxes 41, a plurality of blowing holes 411 are uniformly arranged on the inclined side of each blowing box 41, and the airflow delivered by the high-pressure gas pipes 42, when the powder enters the box body 1 from the first feeding hopper 2 and the second feeding hopper 3, the powder can be blown apart and preliminarily mixed by the blowing assembly 4, and then is stirred by the stirring assembly 5 to be fully and uniformly mixed, so as to avoid the local composition difference caused by uneven mixing of the material, thereby ensuring the product quality, at the same time, the blowing assembly 4 and the stirring assembly 5 work cooperatively, which greatly improves the mixing efficiency and shortens the mixing time, thereby improving the production efficiency.

[0029] As shown in the figure, Figure 2 A plurality of scattering plates 8 are arranged at equal intervals on the inclined side of the blowing box 41 from top to bottom, and the blowing hole 411 is located between two adjacent scattering plates 8, the arrangement of the scattering plate 8 provides mechanical assistance for the initial dispersion of the powder, when different powders enter the box body 1 from the first feeding hopper 2 and the second feeding hopper 3, the powder will slide down along the scattering plate 8 due to the action of gravity, in this process, the agglomerated state of the powder is preliminarily broken, after the powder is preliminarily broken by the scattering plate 8, it is immediately impacted by the high-pressure airflow blown out from the blowing hole 411, at this time, the powder particles are in a relatively loose state, and the airflow can penetrate deeper into the powder to further blow it apart, through the cooperative action of the scattering plate 8 and the blowing hole 411, the powder entering the stirring assembly 5 is more uniform in particle size and distribution state, and the powder can be preliminarily mixed in the process of being blown apart.

[0030] As shown in the figure, Figure 2 The stirring assembly 5 comprises a stirring shaft 51 and a plurality of stirring rods 52, the stirring shaft 51 is rotatably arranged in the box body 1, the lower end of the stirring shaft 51 extends to the outside of the box body 1 and is connected with the output shaft of the driving motor 6, the plurality of stirring rods 52 are uniformly fixed on the stirring shaft 51 and are located below the blowing box 41, the stirring shaft 51 is combined with the plurality of uniformly distributed stirring rods 52, when the stirring shaft 51 rotates under the drive of the driving motor 6, the stirring rods 52 will repeatedly turn over the powder in the area below the blowing box 41, which can fully and sufficiently stir the powder preliminarily treated by the blowing assembly 4.

[0031] As shown in the figure, Figure 2As shown, the upper end of the stirring shaft 51 is fixed to the scraping plate 9, and the scraping plate 9 is located at the lower part of the stirring shaft 51. The scraping plate 9 rotates with the rotation of the stirring shaft 51, and in the process of continuous rotation, the powder can be pushed to the discharge port 7, facilitating the smooth discharge of the powder.

[0032] As shown in Figure 1 and Figure 2 As shown, the discharge port 7 is provided with a blocking plate 10. When the powder needs to be discharged, the blocking plate 10 can be pulled out to adjust the opening size of the discharge port 7, so as to accurately control the speed of the powder flow.

By adjusting the adjusting valve 12, the airflow intensity and flow rate in the blowing box 41 can be changed.

[0034] As shown in Figure 2 The blowing box 41 is provided with a wind distribution plate 13, and the wind distribution plate 13 is uniformly provided with a plurality of through holes. The existence of the wind distribution plate 13 can make the airflow delivered by the high-pressure air pipe 42 uniformly distributed in the blowing box 41, avoid local concentration of the airflow in the blowing box 41, and make the airflow blowing to the powder more uniform and stable.

[0035] As shown in Figure 2 The top of the box body 1 is provided with an exhaust hole 14, and the exhaust hole 14 is provided with an air filter screen 15. When the blowing assembly 4 works, high-pressure gas is blown into the box body 1, which can increase the air pressure in the box body 1. The setting of the exhaust hole 14 can make the excess gas in the box body 1 exhaust, so as to maintain the balance of the air pressure in and outside the box body 1. The setting of the air filter screen 15 can effectively prevent the powder in the box body 1 from leaking to the outside environment with the exhaust gas. In this embodiment, the air filter screen 15 is arranged at the exhaust hole 14 in a clamping manner, which is convenient for disassembly and installation.
