[0096] Working principle:

[0097] The proportioning raw materials are loaded by the inclined loading machine 9. Each time the inclined loading machine 9 is used, only one kind of raw material is delivered. The corresponding second solenoid valve 113 is controlled to open by the controller 12.

[0098] The proportioning feed hopper 4 in the device is used for accurate proportioning, and an annular weighing sensor 42 is used as a weighing component. The measurement threshold of the annular weighing sensor 42 is set by the controller 12. When the weight of the raw materials in the proportioning barrel 43 measured by the annular weighing sensor 42 reaches the threshold, the annular weighing sensor 42 transmits a signal to the controller 12, and the controller 12 controls the first solenoid valve 45 to open, and the weighed raw materials in the proportioning barrel 43 are discharged into the feed hopper assembly 41, and finally discharged into the mixing tank 1. In this way, accurate proportioning is achieved without manual weighing;

[0099] The arrangement of four proportioning barrels 43 and annular weighing sensors 42 can set weighing thresholds for multiple annular weighing sensors 42 at one time, thereby reducing the number of times the weighing thresholds for the annular weighing sensors 42 need to be modified during one proportioning process, thereby simplifying the operation.

However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
