A receiving component is installed on one side of the upper end of the bottom cylinder, and a stirring component is installed inside the temporary storage tank. After the admixture is produced, it is added to the temporary storage tank. The stirring component agitates the admixture inside the temporary storage tank to ensure product quality. Opening the first electromagnetic switch valve allows the admixture to flow through the discharge pipe into the weighing component inside the bottom cylinder. After weighing the required mass, closing the first electromagnetic switch valve simultaneously allows the receiving component to receive any remaining admixture in the discharge pipe, reducing costs and improving metering accuracy.

[0005] Preferably, the weighing component includes an electronic scale, a weighing cylinder, a discharge pipe, and a second electromagnetic switch valve. The electronic scale is installed at the bottom of the bottom cylinder, and the bottom of the weighing cylinder is installed at the top of the electronic scale. The input end of the top of the weighing cylinder is located below the output end of the discharge pipe. The lower part of the right side wall of the weighing cylinder is connected to the discharge pipe, and the second electromagnetic switch valve is installed on the discharge pipe. The first electromagnetic switch valve is opened to allow the additive to be input into the weighing cylinder. The value on the electronic scale is observed. When the value displayed by the electronic scale is greater than 90% of the required weighing mass, the first electromagnetic switch valve is controlled to gradually decrease until it is closed. When the value displayed by the electronic scale is the required weighing mass, the first electromagnetic switch valve is closed to complete the weighing of the additive. Opening the second electromagnetic switch valve allows the additive in the weighing cylinder to be discharged through the discharge pipe.
