[0035] Please see below. Figures 1 to 7 The powder mixing device provided in this embodiment of the utility model specifically includes:

[0036] The weighing assembly 10 includes a weighing chamber 11 and a weighing sensor 12. Multiple weighing chambers 11 are provided, and each weighing chamber 11 is connected to a weighing sensor 12 for independently measuring the weight of different powders and conveying the powders.

[0037] The mixing assembly 20 includes a mixing bin 21 and an agitator 22. The mixing inlet 211 of the mixing bin 21 is located below the weighing outlet 111 of the weighing bin 11. The agitator 22 is located inside the mixing bin 21 and is used to uniformly mix the different powders output from the weighing bin 11.

[0038] A sealed funnel 30 is located at the bottom of the mixing hopper 21 and is used to discharge the mixed powder.

[0039] In this embodiment, by setting up multiple weighing bins 11 and setting up corresponding weighing sensors 12 to weigh each weighing bin 11 independently, the independent measurement and conveying of different powders are ensured, thereby ensuring the accuracy of the powder ratio. Then, through the synergistic effect of the mixing bin 21 and the agitator 22, the powder is uniformly mixed. Finally, the mixed powder is accurately discharged through the sealed funnel 30, ensuring the continuity of the production process and the consistency of powder quality, and improving the overall work efficiency.

[0040] In specific embodiments, the number of weighing bins 11 can be flexibly adjusted according to actual needs. For example, if only three types of powder are to be mixed, only three weighing bins 11 and corresponding weighing sensors 12 need to be set. Of course, multiple weighing bins 11 can also be set, but only some of them can be used for mixing to meet different production needs. This can improve equipment utilization, reduce production costs, and enhance the flexibility and adaptability of the system. It is understood that the position and number of the mixing inlet 211 are matched with the layout and number of the weighing bins 11 (weighing outlet 111).

[0041] In one embodiment, the powder mixing device further includes a stirring drive assembly 40, which is disposed outside the mixing hopper 21 and connected to the stirrer 22 via a linkage shaft for driving the stirrer 22 to rotate.

[0042] In this embodiment, the stirring drive assembly 40 drives the stirrer 22 to rotate via the linkage shaft, thereby using the stirrer 22 to achieve full mixing of the powder in the mixing bin 21 and ensure the uniformity of mixing.

[0043] In one embodiment, the bottom of the weighing bin 11 is a funnel-shaped structure, and the weighing outlet 111 of the weighing bin 11 is located at the bottom of the funnel-shaped structure.

[0044] In this embodiment, the bottom of the weighing bin 11 adopts a funnel-shaped design to effectively prevent powder residue and ensure smooth discharge.

[0045] In one embodiment, a plugging ball 112 is provided inside the weighing chamber 11, which is used to block the weighing discharge port 111;

[0046] A wire guide wheel 113 is installed outside the weighing chamber 11. The wire guide wheel 113 is connected to the plug ball 112 by a traction rope to control the opening and closing of the discharge port.

[0047] In this embodiment, the sealing ball 112 is controlled by the guide wheel 113 and the traction rope to achieve precise opening and closing of the weighing outlet 111, ensuring that the powder is delivered as needed and further optimizing the mixing accuracy. At the same time, the sealing ball 112 is designed to effectively prevent powder leakage, improving the sealing performance and safety of the device.

[0048] In a specific embodiment, the top of the weighing chamber 11 is provided with a weighing inlet and a rope threading port. The weighing inlet is used to add powder, and the rope threading port is used for the traction rope to pass through and connect to the plug ball 112 inside the weighing chamber 11.

[0049] In one embodiment, a mounting frame 23 is provided on the mixing bin 21, and the weighing sensor 12 is mounted on the mounting frame 23;

[0050] A mounting ear 114 is provided on the outside of the weighing chamber 11, and the weighing sensor 12 is connected to the weighing chamber 11 through the mounting ear 114.

[0051] Furthermore, there are two sets of mounting brackets 23, which are symmetrically distributed on both sides of the weighing chamber 11, and each set of mounting brackets 23 supports the corresponding weighing sensor 12.

[0052] In this embodiment, the weighing chamber 11 is securely connected to the weighing sensor 12 via mounting ears 114 and mounted on the mounting bracket 23, ensuring accurate sensor measurement and improving weighing stability. Furthermore, by symmetrically arranging two sets of mounting brackets 23 on both sides of the weighing chamber 11, each supporting a corresponding weighing sensor 12, the balance and measurement accuracy of the weighing system are further enhanced, ensuring the independence and coordination of each weighing chamber 11, and effectively improving the stability and reliability of the overall mixing process.

[0053] In one embodiment, the bottom of the mixing bin 21 has a funnel-shaped structure and is provided with a stirring outlet 212;

[0054] The top of the sealed funnel 30 is provided with a movable block 31 and a material distribution drive assembly 32. The material distribution drive assembly 32 is connected to the movable block 31 and drives the movable block 31 to block or open the mixing outlet 212.

[0055] In this embodiment, the moving block 31 is controlled by the material distribution drive component 32 to achieve flexible opening and closing of the mixing outlet 212, ensuring that the powder is discharged as needed, improving discharge efficiency and sealing performance. At the same time, the funnel-shaped bottom design effectively prevents powder residue and further optimizes the mixing effect.

[0056] Specifically, the material distribution drive component 32 can be a combination of a drive motor and a slide rail. The drive motor drives the moving block 31 on the slide rail to slide through the transmission mechanism, precisely controlling the opening and closing of the mixing outlet 212 to ensure the stability and accuracy of powder conveying.

[0057] In one embodiment, the moving block 31 is provided with a blocking part 311 and a guiding part 312. The blocking part 311 is used to block the mixing outlet 212, and the guiding part 312 is used to form a guiding channel.

[0058] In this embodiment, the sealing part 311 and the guiding part 312 on the moving block 31 are designed to achieve precise sealing and guiding functions of the mixing outlet 212, ensuring efficient discharge of powder. When the powder is being mixed, the material distribution drive assembly 32 drives the sealing part 311 to the mixing outlet 212 and makes the sealing part 311 fit tightly against the mixing outlet 212 to prevent powder leakage. After the powder mixing is completed, the guiding part 312 is driven to the mixing outlet 212 to form a guiding channel, ensuring that the powder is smoothly discharged into the cavity of the sealing funnel 30 and output from the outlet of the sealing funnel 30 for dispensing, thereby improving mixing efficiency and sealing performance.

[0059] In a specific embodiment, the shapes of the sealing part 311 and the guiding part 312 are matched with the mixing outlet 212 to ensure a tight and seamless sealing and guiding process. At the same time, by providing a guiding hole on the guiding part 312, powder can be discharged through the guiding hole when the guiding part 312 is located at the mixing outlet 212.

[0060] In one embodiment, a leak-proof mounting plate 33 is also provided on the top of the sealing funnel 30. An inclined mounting surface is provided on the leak-proof mounting plate 33, which is used to support the bottom of the mixing hopper 21.

[0061] In this embodiment, the leak-proof mounting plate 33 supports the bottom of the mixing hopper 21 via an inclined mounting surface, forming a stable support. It is understood that the angle of the inclined mounting surface corresponds to the tilt angle of the bottom (funnel-shaped structure) of the mixing hopper 21, ensuring that the powder flows smoothly under gravity, avoiding accumulation and blockage.

[0062] In specific application scenarios, the number of anti-leakage mounting plates 33 can be adjusted according to the shape of the bottom of the mixing hopper 21. For example, two anti-leakage mounting plates 33 can be set, corresponding to the two sides of the bottom of the mixing hopper 21 respectively, to ensure uniform support; or, when the bottom shape of the mixing hopper 21 is a right trapezoid with a wider top and a narrower bottom, only one anti-leakage mounting plate 33 can be set, with the tilt angle matching the bottom of the trapezoid.

[0063] In one embodiment, a support foot 50 is provided below the mixing component 20, and the height of the support foot 50 is greater than the height of the sealing funnel 30.

[0064] In this embodiment, a support foot 50 is provided below the mixing component 20 to ensure that the mixing component 20 is placed stably and to prevent tilting or shaking during operation. At the same time, by reasonably setting the height of the support foot 50, sufficient space is created between the mixing component 20 and the ground, facilitating the placement of containers under the sealed funnel 30 for collection, dispensing, and transfer of powder. In a specific embodiment, the height of the support foot 50 can be adjusted according to actual needs to ensure a suitable distance between the mixing component 20 and the ground, facilitating operation while ensuring safety.
