When the drive motor 2 is working, the output shaft 21 rotates and at the same time drives the mixing barrel 4 to rotate through the first transmission assembly 3, which can drive the powder in the mixing barrel 4 to rotate.

[0038] like Figure 3 As shown, the stirring assembly 6 is arranged inside the mixing barrel 4 and is used to stir and mix the powder in the mixing barrel 4 .

[0039] like Figure 5 As shown, the transmission member 22 is fixedly mounted on one end of the output shaft 21 and is used to independently transmit the output of the driving motor 2 .

[0040] Please combine Figure 2 and Figure 3 For reference, the second transmission assembly 5 is arranged between the stirring assembly 6 and the transmission member 22; it is used to transmit the output of the drive motor 2 to the stirring assembly 6. When the output shaft 21 rotates, it drives the second transmission assembly 5 to rotate, and then drives the stirring assembly 6 to rotate, which can stir and mix the powder in the mixing barrel 4.

[0041] like Figure 3 As shown, the filter screen 41 is fixedly mounted on the mixing barrel 4; the door panel 43 is movably arranged on the mixing barrel 4 and adapted to the filter screen 41; the filter screen 41 can filter the mixed powder during discharge and is used to screen the mixed powder mixture. The door panel 43 is adapted to the filter screen 41 to prevent the powder from leaking out when the mixing barrel 4 rotates.

[0042] like Figure 5 As shown, the air pump assembly 8 is arranged on the bracket 1 and is connected to the mixing barrel 4 for pumping gas into the mixing barrel 4, and can blow the powder to mix through the air flow.

[0043] Specifically, the mixing barrel 4 is connected to the output shaft 21 through the first transmission component 3, and then the stirring component 6 and the output shaft 21 are connected through the second transmission component 5 to realize the relative rotation of the stirring component 6 and the mixing barrel 4, thereby improving the stirring and mixing effect. The powder on the edge is brought to the center in sequence through the rotation of the mixing barrel 4, and then the gas is pumped into the mixing barrel 4 and discharged through the air pump component 8, blowing the powders apart from each other to improve the mixing efficiency. Finally, by using the filter screen 41 and the door panel 43 as the discharge port, the filtering effect is achieved while discharging, which can improve the mixing efficiency while increasing the overall mixing rate and reducing the mixing cost.

[0044] Please continue to combine Figure 2 and Figure 5 For reference, in an exemplary embodiment, the first transmission assembly 3 may include a driving bevel gear 31, a fixed plate 111, a transmission bevel gear 32, and a driven bevel gear 33. The driving bevel gear 31 is fixedly sleeved on the output shaft 21, the fixed plate 111 is fixedly mounted on the bracket 1 and is perpendicular to the driving bevel gear 31, the transmission bevel gear 32 is rotatably mounted on the fixed plate 111 and meshes with the driving bevel gear 31, and the driven bevel gear 33 is fixedly mounted at one end of the mixing barrel 4 and meshes with the transmission bevel gear 32.

[0045] Specifically, when the output shaft 21 rotates, it drives the active bevel gear 31 fixedly connected to it to rotate. When the active bevel gear 31 rotates, it drives the transmission bevel gear 32 meshing with it to rotate. When the transmission bevel gear 32 rotates, it drives the driven bevel gear 33 meshing with it to rotate. The driven bevel gear 33 then drives the mixing barrel 4 fixedly connected to it to rotate, which can drive the powder in the mixing barrel 4 to rotate. Through the transmission of the bevel gear set, the rotation direction of the mixing barrel 4 can be opposite to the rotation direction of the output shaft 21.

[0046] Please continue to combine Figure 3 and Figure 4 For reference, in an exemplary embodiment, the second transmission assembly 5 may include a sun gear 51, a ring gear 52, planetary gears 53, and a connecting shaft 511. The sun gear 51 is rotatably mounted on the inner wall of the mixing barrel 4, the ring gear 52 is fixedly mounted on the inner wall of the mixing barrel 4, the planetary gears 53 are movably mounted between the ring gear 52 and the sun gear 51, and mesh with the ring gear 52 and the sun gear 51. The connecting shaft 511 is fixedly mounted on the sun gear 51, one end of which extends to the outside of the mixing barrel 4 and is fixedly connected to the transmission member 22, and the other end of which extends to the inside of the mixing barrel 4.

[0047] Specifically, when the output shaft 21 rotates, it drives the transmission member 22 to rotate, and further drives the connecting shaft 511 and the sun gear 51 fixedly connected thereto to rotate. The ring gear 52 is fixed on the mixing barrel 4. When the sun gear 51 rotates, the planetary gear 53 will rotate while rotating around the sun gear 51, and the direction of rotation is consistent with the direction of rotation of the output shaft 21, thereby rotating relative to the mixing barrel 4 to enhance the stirring effect.

[0048] Please continue to combine Figure 3 and Figure 4 For reference, in an exemplary embodiment, the stirring assembly 6 may include a stirring rod 61 and branch stirring rods 62. The stirring rod 61 is fixedly mounted on one end of the planetary gear 53, and four branch stirring rods 62 are provided in an L-shaped manner, fixedly mounted on the stirring rod 61 and distributed in a ring array.

[0049] Specifically, the planetary gear 53 rotates while rotating around the sun gear 51, and drives the stirring rod 61 to rotate while rotating, and then drives the branch stirring rod 62 to rotate around it, which can improve the stirring effect and better mix the powder.

[0050] Please continue to combine Figure 3 、 Figure 4 and Figure 10 For reference, in an exemplary embodiment, the air pump assembly 8 may include a support plate 13, an air pump barrel 81, an air inlet 811, an air outlet 812, a connecting rod 82, a mounting rod 83, a piston 831, a rotary joint 1 84, an air outlet pipe 841, a rotary joint 2 85, a rotary joint 3 86, an air guide pipe 851 and a one-way valve assembly 9. Among them, the support plate 13 is fixedly mounted on the bracket 1, the air pump barrel 81 is fixedly mounted on the upper end surface of the support plate 13, the air inlet 811 is arranged on the outer wall of the air pump barrel 81, and the air outlet 812 is arranged on the outer wall of the air pump barrel 81, the connecting rod 82 is rotatably sleeved on the transmission member 22, the mounting rod 83 is hinged at one end of the connecting rod 82, the piston 831 is fixedly mounted at one end of the mounting rod 83 and extends into the air pump barrel 81, the rotary joint 84 is arranged at the end of the connecting shaft 511 located on the outside of the mixing barrel 4, the air outlet pipe 841 is arranged between the rotary joint 84 and the air outlet 812, the rotary joint 2 85 is arranged at the end of the connecting shaft 511 located on the inside of the mixing barrel 4, the rotary joint 3 86 is arranged on the stirring rod 61, the air guide pipe 851 is arranged between the rotary joint 2 85 and the rotary joint 3 86, and two one-way valve assemblies 9 are provided, and the two one-way valve assemblies 9 are respectively fixedly mounted on the air inlet 811 and the air outlet 812.

[0051] Specifically, the transmission member 22 transmits the rotation of the output shaft 21 to the mounting rod 83 through the connecting rod 82, and the mounting rod 83 performs up and down reciprocating motion, so that the piston 831 reciprocates up and down in the air pump barrel 81. When the piston 831 moves upward, the air outlet 812 is closed under the action of the one-way valve assembly 9, and the air inlet 811 is opened, and gas enters the air pump barrel 81 from the outside. When the piston 831 moves downward, the air inlet 811 is closed, and the air outlet 812 is opened, and the gas is pumped out from the air pump barrel 81, flows to the rotary joint 1 84 through the air outlet pipe 841, enters the interior of the mixing barrel 4, and then enters the stirring assembly 6 through the rotary joint 2 85, the air guide pipe 851 and the rotary joint 3 86. While assisting the stirring, the air flow can make the powder dispersion and mixing more uniform.

[0052] Furthermore, the transmission member 22 is a U-shaped connecting rod, the connecting shaft 511 is hollow, an air path 621 is opened in the stirring rod 61 and the branch stirring rod 62, and a plurality of air guide holes 622 are opened on the branch stirring rod 62, and the air guide angles of the air guide holes 622 are distributed in a W shape.

[0053] Specifically, the U-shaped transmission part 22 acts as a crank and forms a reciprocating motion mechanism with the connecting rod 82 and the mounting rod 83. The hollow connecting shaft 511 allows gas to flow from the connecting shaft 511 to the stirring assembly 6. The air guide holes 622 opened on the branch stirring rod 62 are distributed in a W shape, which allows the air flows to impact each other and blow the powder evenly in all directions.

[0054] In one embodiment, the one-way valve assembly 9 may include a fixed sleeve 91, a rotating shaft 92, and a valve plate 93. The fixed sleeve 91 is fixedly mounted on the vent, the rotating shaft 92 is rotatably mounted in the fixed sleeve 91, and the valve plate 93 is fixedly connected to the rotating shaft 92 and adapted to the vent.

[0055] Specifically, when the gas pushes the valve plate 93 on one side, the valve plate 93 rotates around the fixed sleeve 91 through the rotating shaft 92, so that the gas can pass through smoothly. When the gas pushes the valve plate 93 from the other side, the valve plate 93 is limited and thus plays a role in preventing the gas from passing through.

[0056] Please combine Figure 7-Figure 9 For reference, in an exemplary embodiment, a door panel groove 42 is provided on the mixing barrel 4 at a position corresponding to the filter screen 41, a door panel 43 is slidably provided in the door panel groove 42, an adjustment component 7 is provided on the door panel 43, and a sliding groove 44 adapted to the adjustment component 7 is provided at one end of the mixing barrel 4.

[0057] Specifically, the door panel 43 can slide in the door panel groove 42. When it slides to one side, the powder can be poured out of the mixing barrel 4 through the filter screen 41. When the door panel 43 slides to the position corresponding to the filter screen 41, the powder can be prevented from leaking, so that the mixing barrel 4 can rotate normally to mix the powder. The adjustment component 7 is used to control the movement of the door panel 43. One end of the adjustment component is connected to the door panel 43, and the other end extends out of the mixing barrel 4 through the sliding groove 44, which is convenient for controlling the movement of the door panel 43.

[0058] Furthermore, the adjustment assembly 7 may include a fixing rod 71, an external thread 711, a handle 72, and an internal thread 721. The fixing rod 71 is fixedly mounted on one end of the door panel 43, the external thread 711 is provided on the end of the fixing rod 71 away from the door panel 43, the handle 72 is provided on the fixing rod 71, and the internal thread 721 is provided on the inner wall of the handle 72 and is adapted to the external thread 711.

[0059] Specifically, rotating the handle 72 can adjust the distance between the handle 72 and the outer wall of the mixing barrel 4. When the handle 72 is away from the mixing barrel 4, the position of the door panel 43 can be driven by moving the handle 72. When the handle 72 is rotated in the opposite direction to squeeze it against the mixing barrel 4, the position of the door panel 43 can be fixed, thereby achieving the function of controlling the switch state of the door panel 43.

[0060] See also Figure 3 A plurality of inclined blocks 45 distributed in a circular array are fixedly mounted on the inner wall of the mixing barrel 4 .

[0061] The inclined block 45 is matched with the rotation direction of the mixing barrel 4. The mixing barrel 4 rotates counterclockwise. The right-angled side on one side of the inclined block 45 is connected to the mixing barrel 4, and the right-angled side on the other side is relatively located on the clockwise side. Through this arrangement, the powder on the right side of the mixing barrel 4 can naturally slide down along the inclined surface of the inclined block 45 under the action of gravity, and the powder on the left side of the mixing barrel 4 moves to the right under the action of the inclined surface of the inclined block 45, thereby improving the friction effect of the mixing barrel 4 on the powder and improving the effect of the rotation of the mixing barrel 4 on the powder mixing.

[0062] See also Figure 2 The driving motor 2 is provided with a dustproof box 11 , the output end of the driving motor 2 extends out of the dustproof box 11 , the stirring rod 61 is provided with a dustproof plate 46 , and the dustproof plate 46 is rotatably connected to the mixing barrel 4 .

[0063] The device works in a dusty environment, and the dustproof box 11 can prevent dust from entering the drive motor 2 and reducing its service life. A dustproof plate 46 is also provided to protect the working life of the gear set.

[0064] The powder mixing device with filtering function proposed in the embodiment of the present application can realize the rotation of the stirring component 6 and the mixing barrel 4 in opposite directions through the first transmission component 3 and the second transmission component 5. The powder on the edge is brought to the center in sequence through the rotation of the mixing barrel 4, and then the gas is pumped into the mixing barrel 4 through the pump air component 8 and discharged, thereby assisting the separation of powders from each other and improving the mixing efficiency. By using the filter screen 41 and the door panel 43 to discharge the material, the filtering effect is achieved while discharging the material, which can improve the mixing efficiency while increasing the overall mixing rate and reducing the mixing cost.
