The mixing box 2 is provided below the raw material box 1, and serves to temporarily store the raw materials that fall in proportion. The stirring device 3 is located below the mixing box 2, and serves to fully stir the falling mixed materials.

[0032] The storage box 11 is arranged at the top of the device, and multiple ones are arranged according to the number of raw material types, which plays the role of storing raw materials. The discharge port 12 is located below the storage box 11, which plays the role of allowing raw materials to pass through while fixing components such as the magnet 14 and the fixed frame 13. The limit groove 121 is arranged on both sides of the discharge port 12 from left to right, which plays the role of limiting the movable direction of the baffle 17. The mounting groove 122 is symmetrically arranged above and below both sides of the limit groove 121, which plays the role of installing the magnet 14. The fixed frame 13 is arranged on both sides of the mounting groove 122 on the discharge port 12, which plays the role of limiting the movable range of the electromagnet 15. The movable hole 131 is the fixed frame 1 3 and the discharge port 12 form a space for the power supply magnet 15 and the baffle 17 to move, the magnet 14 is fixedly arranged in the installation groove 122, coincides with the electromagnet 15, and the south pole of the magnet 14 faces the electromagnet 15, the electromagnet 15 is arranged in the movable hole 131, the magnet 14 and the electromagnet 15 cooperate with each other to drive the baffle 17 to move, the slide rail 16 is arranged on both sides of the baffle 17, the slide rail 16 and the limiting groove 121 cooperate with each other to limit the moving direction of the baffle 17, the baffle 17 is fixedly connected to the electromagnet 15 respectively, and moves with the interaction between the electromagnet 15 and the magnet 14, so as to block or open the discharge port 12;

[0033] The mixing box 2 is composed of a temporary storage box 21, a weighing sensor 22, and a support frame 23. The structure of the temporary storage box 21 is consistent with that of the raw material box 1. The weighing sensor 22 is arranged below the temporary storage box 21 to generate weight data in the temporary storage box 21. The support frame 23 is located below the weighing sensor 22 to support the weighing sensor 22.

[0034] The stirring device 3 is arranged below the mixing box 2, and is composed of a transmission channel 31, a stirrer 32, and a stirring barrel 33. The transmission channel 31 is wide at the top and narrow at the bottom, and is in contact with multiple mixing boxes 2 at the top. The stirrer 32 is arranged at the narrow part at the bottom. The mixed material is initially stirred by the stirrer 32 during the process of falling to the stirring barrel 33 under the action of gravity. The stirring barrel 33 is arranged below the transmission channel 31, and plays the role of fully stirring the mixed material after the initial stirring again.

[0035] Working principle of this utility model:

[0036] Before use, the trigger value of the weighing sensor 22 under the corresponding mixing box 2 is adjusted according to the required weight of each raw material. After starting the device, the weighing sensor 22 senses that the value in the temporary storage box 21 has not reached the target value, and transmits the signal to the electromagnet 15 on the raw material box 1 and the electromagnet 15 on the temporary storage box 21, controlling the electromagnet 15 on the raw material box 1 to be energized and generate a magnetic field of the south pole. Like poles repel each other, and the electromagnet 15 on the raw material box 1 drives the baffle 17 to move in the direction away from the discharge port 12, and then the raw material box The electromagnet 15 on the temporary storage box 21 contacts the fixed frame 13 on the raw material box 1, and the baffle 17 completes the opening of the discharge port 12. While controlling the electromagnet 15 on the raw material box 1 to be energized, the electromagnet 15 on the temporary storage box 21 is also energized. However, the magnetic field generated by the electromagnet 15 on the temporary storage box 21 is the North Pole. Opposites attract each other, and the electromagnet 15 on the temporary storage box 21 and the magnet 14 on the temporary storage box 21 are mutually attracted to complete the blocking of the discharge port 12 on the temporary storage box 21. When the required minimum proportion of raw materials is located under the temporary storage box 21, the electromagnet 15 on the temporary storage box 21 is energized. After the value of the weighing sensor 22 on the right side reaches the target value, the weighing sensor 22 controls the current of the electromagnet 15 on the corresponding raw material box 1 to be opposite, so that the direction of the magnetic field generated by the corresponding electromagnet 15 is opposite to that before, so that the discharge port 12 on the raw material box 1 is blocked, and the temporary storage box 21 stops feeding until the weighing sensors 22 under all the temporary storage boxes 21 reach the target value to block the discharge port 12 on the raw material box 1. The weighing sensor 22 controls the electromagnet 15 on the temporary storage box 21 to generate a magnetic force in the opposite direction, and the temporary storage box 21 stops feeding. The discharge port 12 on the box 21 is opened, and multiple raw materials are initially stirred by the agitator 32 in the transmission channel 31 at the same time. When all the raw materials in the temporary storage box 21 are emptied, the weighing sensor 22 controls the electromagnet 15 on the raw material box 1 and the electromagnet 15 on the temporary storage box 21 to simultaneously open the discharge port 12 on the raw material box 1 and close the discharge port 12 on the temporary storage box 21, and repeat the next round of proportional feeding work. At the same time, the stirring barrel 33 fully stirs the mixed material after the initial stirring after passing through the transmission channel 31.
