This not only greatly reduces the workload of the staff, but also effectively eliminates the potential risk of raw material contamination as much as possible.

[0018] Furthermore, such as Figure 5 As shown, the support frame 2 includes a support frame base 5, an installation base 6 disposed on the support frame base 5, and a reinforcing connecting rod 7 installed between the support frame base 5 and the installation base 6. The support frame base 5 facilitates the fixed support of the installation base 6 and part of the jet cleaning structure 1 in the mixing chamber. The installation base 6 facilitates the fixed support of the powder mixing structure 3. The reinforcing connecting rod 7 facilitates the increase of the connection strength between the support frame base 5 and the installation base 6.

[0019] Furthermore, such as Figure 2 and Figure 3 As shown, the jet cleaning structure 1 of the mixing chamber includes a disc nozzle 8, air pumps 9 symmetrically arranged on the upper surface of the support plate 5, and a connecting pipe 10 connecting the air pumps 9 and the disc nozzle 8. The air pumps 9 are bolted to the support plate 5. The air pumps 9 provide compressed gas for the jet of the disc nozzle 8. The connecting pipe 10 allows the compressed gas generated by the air pumps 9 to enter the disc nozzle 8. The disc nozzle 8 allows the gas delivered by the two air pumps 9 to be sprayed out evenly. Here, the two air pumps 9 are existing device modules, so their working principle is the existing device, and therefore will not be described in detail here.

[0020] Furthermore, such as Figure 3 and Figure 4As shown, the powder mixing and stirring structure 3 includes a working chamber 11, a feed inlet 12 located near the upper side of the working chamber 11, a feed cover 13 embedded in the feed inlet 12, a discharge outlet 14 located on the lower end face of the working chamber 11, a discharge cover 15 embedded in the discharge outlet 14, a rotating shaft 16 rotatably disposed in the working chamber 11, stirring blades 17 evenly and equidistantly disposed outside the rotating shaft 16, and a drive assembly 29 mounted on the top of the working chamber 11. The working chamber 11 facilitates the mixing of powder. The inlet 12 facilitates the injection of several powder materials to be mixed into the working tank cavity 11. The inlet cover 13 facilitates the sealing of the inlet 12. The outlet 14 facilitates the discharge of the powder material after mixing into the working tank cavity 11. The outlet cover 15 facilitates the sealing of the outlet 14. The rotating shaft 16 facilitates the rotational support of the stirring blade 17. The edge of the stirring blade 17 uniformly stirs several powder materials to be mixed in the working tank cavity 11. The drive assembly 29 facilitates the provision of driving force for the rotation of the rotating shaft 16.

[0021] Furthermore, such as Figure 3 , Figure 4 as well as Figure 5 As shown, the outer surfaces of the upper and lower ends of the working tank cavity 11 are provided with several snap-fit ​​protrusions 21. The upper and lower ends of the working tank cavity 11 are both mounted on the mounting base 6 by snap-fit ​​mounting buckles 18. The snap-fit ​​mounting buckle 18 includes a first snap-fit ​​seat 19, a second snap-fit ​​seat 20 mounted on the first snap-fit ​​seat 19, and snap-fit ​​grooves 22 formed on the first snap-fit ​​seat 19 and the second snap-fit ​​seat 20 that are adapted to the snap-fit ​​protrusions 21.

[0022] Furthermore, such as Figure 4 As shown, the top end of the rotating shaft 16 passes through the working tank cavity 11. The drive assembly includes a drive motor 23, a first bevel gear 24 installed at the output end of the drive motor 23, and a second bevel gear 25 disposed at the top end of the rotating shaft 16. The first bevel gear 24 and the second bevel gear 25 mesh with each other. The drive motor 23 provides driving force for the rotation of the first bevel gear 24. The meshing of the first bevel gear 24 and the second bevel gear 25 facilitates the drive motor 23 to drive the rotating shaft 16 to rotate.

[0023] Furthermore, such as Figure 3 As shown, the disc nozzle 8 is installed at the top of the working tank cavity 11. The disc nozzle 8 is rotatably mounted on the rotating shaft 16, and the connecting pipe 10 passes through the working tank cavity 11 and connects to the disc nozzle 8.

[0024] Furthermore, such as Figure 3 and Figure 4 As shown, the feed cover 13 is installed on the feed inlet 12 by the first butterfly bolt 26, and the discharge cover 15 is installed on the discharge outlet 14 by two rotating buckles 27. The feed cover 13 is provided with a first handle 28 on its outer side, and the discharge cover 15 is provided with a second handle 4 on its lower end face. The first butterfly bolt 26 facilitates fixing the feed cover 13 on the feed inlet 12, and the rotating buckles 27 facilitate fixing the discharge cover 15 on the discharge outlet 14 by turning and flipping. The first handle 28 is used to pick up the feed cover 13, and the second handle 4 is used to pick up the discharge cover 15.

[0025] like Figures 1-5 As shown, the principle of the powder mixing and stirring device for manufacturing metal materials provided in this embodiment is as follows: When using this device, it should first be connected to the control terminal computer, and then the device should be controlled by the control terminal computer to perform the powder mixing operation and the subsequent air jet cleaning operation. When the device starts working, the operator first manually rotates and removes the first wing bolt 26, then holds the first handle 28 to remove the feed cover 13, and then injects a certain amount of powder raw materials to be mixed into the working tank cavity 11 through the feed port 12. After that, the feed cover 13 is fixedly installed on the feed port 12 by the first wing bolt 26. Then, the drive motor 23 is controlled by the control terminal computer to start the operation. The drive motor 23 will drive the first bevel gear 24 to start rotating. Since the first bevel gear 24 and the second bevel gear 25 mesh and match, the rotating shaft 16 will start to rotate. The rotating shaft 16 will drive the stirring blade 17 to rotate. The rotating stirring blade 17 will stir and mix the powder raw materials to be mixed in the working tank 11. After the powdered raw materials in the working tank 11 are mixed, the drive motor 23 can be stopped by the control terminal computer. Then, the operator can turn the flip buckle 27 and then hold the second handle 4 to remove the discharge cover 15. The mixed powdered raw materials are then discharged from the working tank 11 through the discharge port 14. At this time, the drive motor 23 can be restarted by the control terminal computer, so that the mixed powdered raw materials can be discharged from the working tank 11 more quickly. After the mixed powder materials in the working tank 11 are discharged as much as possible, the drive motor 23 can be stopped by the control terminal computer. Then, the two air pumps 9 are started by the control terminal computer. The air pumps 9 will generate a large amount of compressed gas. This large amount of compressed gas will enter the disc nozzle 8 through the connecting pipe 10. Then, this large amount of compressed gas will be sprayed evenly and quickly out of the working tank 11 through the disc nozzle 8. At this time, the compressed gas sprayed evenly and quickly out of the disc nozzle 8 will perform air jet cleaning on the working tank 11, the rotating shaft 16 and the stirring blades 17. At this time, the discharge port 14 is always open so that the powder material cleaned by air jet can be discharged from the working tank 11 to the outside. After the air jet cleaning of the working chamber 11 is completed, the two air pumps 9 can be stopped by controlling the control terminal computer. Then, the operator can turn the flip-rotate buckle 27 to fix the discharge cover 15 on the discharge port 14. The device can then wait for the next mixing operation. When using this device, the following should be noted: when air jet cleaning, the discharge port must be fully opened to avoid excessive air pressure in the chamber, which may damage the components. The stirring blades should be checked for wear regularly to prevent the blades from breaking and mixing in powder. The air pumps should use dry compressed gas (moisture content ≤0.1%) to avoid moisture causing metal powder to clump.
