Specific embodiments

[0033] To make the technical solution of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0034] Embodiment 1

[0035] As Figure 1-2 , this embodiment provides an automatic mixing device, including: a mixing material bin 1, a first outlet 11 of the mixing material bin 1 is connected to a first valve body 71, and the first outlet 11 of the mixing material bin 1 is used for being intermittently connected to a production device; a liquid material bin 2, a second outlet 21 of the liquid material bin 2 is intermittently connected to the mixing material bin 1, and the second outlet 21 of the liquid material bin 2 is connected to a second valve body 72; a powder material bin 3, a third outlet 31 of the powder material bin 3 is connected to a conveying assembly 4, and the conveying assembly 4 is also intermittently connected to the mixing material bin 1; a weighing sensor 5 connected to the mixing material bin 1; and a stirring assembly 6 at least partially located in the mixing material bin 1.

[0036] Specifically, during operation, first open the second valve body 72 so that the liquid material in the liquid material bin 2 enters the mixing material bin 1 through the second outlet 21. When the weighing sensor 5 shows the first preset mass (the first preset mass is the mass of the required liquid material), close the second valve body 72. Then turn on the conveying component 4, and the conveying component 4 conveys the powder in the powder bin 3 to the mixing material bin 1 through the third outlet 31. When the weighing sensor 5 shows the second preset mass (the second preset mass is the sum of the mass of the required liquid material and the mass of the required powder), turn off the conveying component 4. Then turn on the stirring component 6 to fully mix the liquid material and the powder. Finally, open the first valve body 71 so that the mixed material in the mixing material bin 1 enters the relevant production equipment through the first outlet 11. It should be noted that during operation, the conveying component 4 can also be turned on first and then the second valve body 72, that is, the powder is conveyed first and then the liquid material. The subsequent processes are similar and will not be elaborated here. In summary, the automatic mixing device of the present application realizes automatic mixing through the second valve body 72, the conveying component 4, the weighing sensor 5, the stirring component 6, etc., which facilitates reducing the labor intensity. At the same time, the weighing sensor 5 facilitates reducing the error rate.

[0037] The mixing material bin 1 is used to accommodate the mixed material and transfer the mixed material to the relevant production equipment. Since the first outlet 11 of the mixing material bin 1 is used to communicate with the production equipment at intervals, it is convenient to prevent the weighing of the weighing sensor 5 from being interfered by the relevant production equipment. The first valve body 71 is used to control the opening and closing of the first outlet 11 of the mixing material bin 1. The first valve body 71 can be a ball valve, a butterfly valve, etc., and is preferably a ball valve. The liquid material bin 2 is used to accommodate the liquid material. Since the second outlet 21 of the liquid material bin 2 communicates with the mixing material bin 1 at intervals, it is convenient to prevent the weighing of the weighing sensor 5 from being interfered by the liquid material bin 2. The second valve body 72 is used to control the opening and closing of the second outlet 21 of the liquid material bin 2. The second valve body 72 can be a ball valve, a butterfly valve, etc., and is preferably a ball valve. The powder bin 3 is used to accommodate the powder. The conveying component 4 is used to convey the powder from the third outlet 31 of the powder bin 3 to the mixing material bin 1. The conveying component 4 can be a screw conveying component, a belt conveying component, etc., and is preferably a screw conveying component. Since the conveying component 4 also communicates with the mixing material bin 1 at intervals, it is convenient to prevent the weighing of the weighing sensor 5 from being interfered by the conveying component 4. The weighing sensor 5 is used to weigh the mixing material bin 1. The weighing sensor 5 can be a capacitive weighing sensor, a plate ring weighing sensor, etc. The stirring component 6 is used to stir the mixed material in the mixing material bin 1.

[0038] Further, as Figure 1-2 , the first inlet 121 of the mixing material bin 1 communicates with the second outlet 21 of the liquid material bin 2 at intervals, and the second inlet 122 of the mixing material bin 1 communicates with the fourth outlet 411 of the conveying component 4 at intervals.

[0039] Further, as Figure 1-2, the inner diameter of the first inlet one 121 of the mixing material bin 1 is greater than the outer diameter of the second outlet 21 of the liquid material bin 2, and the inner diameter of the second inlet 122 of the mixing material bin 1 is greater than the outer diameter of the fourth outlet 411 of the conveying assembly 4. Specifically, the inner diameter of the first inlet one 121 of the mixing material bin 1 is relatively large, and the outer diameter of the second outlet 21 of the liquid material bin 2 is relatively small, which is convenient for preventing the leakage of liquid materials; the inner diameter of the second inlet 122 of the mixing material bin 1 is relatively large, and the outer diameter of the fourth outlet 411 of the conveying assembly 4 is relatively small, which is convenient for preventing the leakage of powder materials.

Specifically, the first hose 81 is convenient for further preventing the leakage of liquid materials and for minimizing the interference of the liquid material bin 2 on the weighing of the weighing sensor 5 to the greatest extent; the second hose 82 is convenient for further preventing the leakage of powder materials and for minimizing the interference of the conveying assembly 4 on the weighing of the weighing sensor 5 to the greatest extent; the materials of the first hose 81 and the second hose 82 can be silicone, PVC, etc.

[0041] Furthermore, as Figure 2 , the conveying assembly 4 includes: a conveying pipe 41, one end of the conveying pipe 41 is connected to the third outlet 31 of the powder material bin 3, and the other end of the conveying pipe 41 is connected to the mixing material bin 1; a screw conveying unit 42 at least partially located in the conveying pipe 41. Specifically, the conveying pipe 41 is used to connect the third outlet 31 of the powder material bin 3 and the mixing material bin 1; the screw conveying unit 42 is used to convey powder materials.

Specifically, the output shaft of the first driver 421 drives the screw conveying blade 422 to rotate, and the screw conveying blade 422 is used to convey powder materials, and the first driver 421 can be a servo motor, a stepping motor, etc.

[0043] Furthermore, as Figure 1 , the stirring assembly 6 includes: a second driver 61; a stirring blade 62 connected to the output shaft of the second driver 61; wherein, the stirring blade 62 is located in the mixing material bin 1. Specifically, the output shaft of the second driver 61 drives the stirring blade 62 to rotate, and the stirring blade 62 is used to stir the mixture in the mixing material bin 1.

Specifically, the liquid material in the liquid storage bin 2 should be located between the first low liquid level line 912 and the first high liquid level line 911. The first observation window one and the first observation window two facilitate the staff to observe. The materials of the first observation window one and the first observation window two are transparent glass or plastic; the powder in the powder storage bin 3 should be located between the second low liquid level line 922 and the second high liquid level line 921.
