[0035] Four stirring rods 23 are provided, fixedly mounted on the rotating plate 22 and distributed in a circular array. The stirring rods 23 can rotate with the rotating plate 22 to stir the powder in the mixing barrel 2 for mixing.

[0036] Please combine Figure 1 、 Figure 2 and Figure 3 For reference, the power assembly 3 is fixedly mounted at the bottom of the bracket 1, and is used to provide power for stirring and mixing and power for cleaning. The gear 1 24 is fixedly mounted on one end of the central shaft 21 extending out of the mixing barrel 2 and is connected to the power assembly 3. The power assembly 3 outputs power to the gear 1 24, and the gear 1 24 drives the central shaft 21 and the stirring rod 23 to rotate.

[0037] like Figure 2 As shown, the cleaning component 4 is arranged inside the mixing barrel 2 and is used to clean the powder residue in the mixing barrel 2.

[0038] Specifically, during stirring, the power component 3 cooperates with the gear 1 24, the power component 3 drives the gear 1 24 to rotate, and the gear 1 24 further drives the central shaft 21 to rotate, thereby driving the rotating plate 22 and the stirring rod 23 fixed on the rotating plate 22 to stir the powder in the mixing barrel 2.

[0039] like Figure 2 and Figure 3 As shown, the cleaning component 5 is fixedly installed at the bottom of the bracket 1 and is connected to the cleaning component 4.

[0040] Specifically, the cleaning component 5 is connected to the cleaning component 4 , and the cleaning component 4 sprays water to clean the interior of the mixing barrel 2 .

[0041] Please continue to combine Figure 2 and Figure 3 For reference, in an exemplary embodiment, the power assembly 3 may include an electric push rod 34, a motor bracket 31, a drive motor 32, and a drive gear 33.

[0042] Specifically, when the powder mixing device needs to work, the output end of the driving motor 32 rotates the driving gear 33, and the driving gear 33 drives the gear 1 24 meshing with it to rotate. The motor bracket 31 is used to fix the position of the driving motor 32.

[0043] Please continue to combine Figure 4 、 Figure 5 and Figure 6 For reference, in an exemplary embodiment, the cleaning assembly 4 may include a reciprocating screw sleeve 41, a guide block 42, a guide rod 411, a cleaning disc 43, bristles 431, and a second gear 44. The reciprocating screw sleeve 41 is rotatably mounted on the central shaft 21, with one end extending out of the mixing barrel 2. The guide block 42 is mounted on the reciprocating screw sleeve 41 and is provided with an internal thread that matches the reciprocating screw sleeve 41. The guide rod 411 is fixedly installed in the mixing barrel 2 and passes through the guide block 42. The cleaning disc 43 is mounted on the guide block 42. The bristles 431 are fixedly mounted on the outer wall of the cleaning disc 43. The second gear 44 is fixedly mounted on the end of the reciprocating screw sleeve 41 that extends out of the mixing barrel 2.

[0044] Specifically, when cleaning is required, the electric push rod 34 pushes the motor bracket 31 to move upward, so that the driving gear 33 and gear 2 44 engage with each other. When the driving gear 33 rotates, it drives gear 2 44 to rotate, and gear 2 44 then drives the reciprocating screw sleeve 41 to rotate. Under the action of the guide rod 411, the guide block 42 drives the cleaning disc 43 to reciprocate up and down, and cleans the barrel wall of the mixing barrel 2 through the brush bristles 431.

[0045] Please combine Figure 3 、 Figure 7 and Figure 9For reference, in an exemplary embodiment, the cleaning assembly 5 may include a water tank 51, a water outlet pipe 52, a water pump 521, a water return pipe 53, a water pipe valve 531, a handle 532, a drying assembly 54, and a cleaning hole 432. The water tank 51 is fixedly mounted at the bottom of the bracket 1, the water outlet pipe 52 is disposed between the cleaning tray 43 and the water tank 51 and passes through the mixing barrel 2, the water pump 521 is disposed on the water outlet pipe 52, the water return pipe 53 is disposed between the mixing barrel 2 and the water tank 51, the water pipe valve 531 is disposed at the top of the water return pipe 53, the handle 532 is disposed on the water pipe valve 531, the drying assembly 54 is disposed on the water tank 51, the cleaning hole 432 is formed on the upper end surface of the cleaning tray 43, a passage is formed in the cleaning tray 43, and the water outlet pipe 52 is connected to the passage in the cleaning tray 43.

[0046] Specifically, the water pump 521 pumps the water in the water tank 51 into the water outlet pipe 52, and the water outlet pipe 52 passes through the bottom of the mixing barrel 2 and is connected to the cleaning disk 43, and is sprayed out from the cleaning hole 432 on the cleaning disk 43 to clean the inner wall of the mixing barrel 2. The cleaned water flows through the bottom of the mixing barrel 2 and flows back to the water tank 51 from the return pipe 53, so that the water can be recycled and water resources are saved. When the cleaning task is not in progress, the water pipe valve 531 can be closed by the handle 532 to prevent powder from falling into the return pipe 53. After cleaning is completed, the water stains left in the mixing barrel 2 after cleaning can be quickly dried by the drying component 54.

[0047] Furthermore, the drying assembly 54 may include an air pipe 541 and air holes 433. The air pipe 541 is fixedly mounted on the top of the water tank 51 and passes through the mixing barrel 2 to connect to the cleaning plate 43. The air holes 433 are provided on the side and lower end surface of the cleaning plate 43. An air path is provided in the cleaning plate 43, and the air pipe 541 is connected to the air path.

[0048] Specifically, after the water in the water tank 51 is heated to boiling, the generated water vapor will flow upward along the air pipe 541, which is connected to the cleaning plate 43, and will be ejected from the air holes 433 on the cleaning plate 43 to dry the mixing barrel 2.

[0049] In one embodiment, a plurality of upwardly inclined guide plates 542 are disposed in the air pipe 541 .

[0050] It is understandable that when the water vapor contacts the guide plate 542 during its upward movement, the water vapor will condense and flow back to the water tank 51 along the guide plate 542 , and the guide plate 542 can pressurize the water vapor.

[0051] In one embodiment, a heating ring 55 is provided at the bottom of the water tank 51 .

[0052] It can be understood that the water in the water tank 51 is heated to boiling by the heating ring 55 .

[0053] Please combine Figure 2 and Figure 8 As shown in FIG. 4 , the cleaning hole 432 and the air hole 433 are both W-shaped. A one-way valve 533 is provided at the position where the water tank 51 is connected to the return pipe 53. A filter device (not shown) is provided at one end of the outlet pipe 52 connected to the water tank 51. A hose is provided between the outlet pipe 52 and the air pipe 541.

[0054] Specifically, the W-shaped air holes 433 and cleaning holes 432 can direct the water flow and air flow toward the inner wall of the mixing barrel 2 and the stirring rod 23, so as to better clean the mixing barrel 2. The one-way valve 533 can prevent the gas from entering the mixing barrel 2 through the return pipe 53, and the air pipe 541 and the outlet pipe 52 can reciprocate up and down with the cleaning disc 43.

[0055] The powder mixing device with automatic cleaning function proposed in the embodiment of the present application outputs power to the central shaft 21 through the power component 3, driving the stirring rod 23 to mix the powder in the mixing barrel 2, and then drives the cleaning disc 43 to reciprocate up and down to clean the inner wall of the mixing barrel 2 through the reciprocating screw sleeve 41 and the guide rod 411, and then is connected to the cleaning disc 43 through the cleaning component 5, and water is sprayed through the cleaning disc 43 to clean the inside of the mixing barrel 2, and finally is connected to the cleaning disc 43 through the drying component 54 to dry the barrel. Through the above mechanism, not only can the mixing barrel 2 be cleaned conveniently after mixing, but also the time of the drying machine can be reduced, the equipment utilization rate can be guaranteed, and the mixing efficiency can be improved.

[0056] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application.
