AI Technical Summary

Technical Problem

Existing expansion agent metering and proportioning devices have difficulty controlling the amount of raw materials with smaller required weights when the weighing instrument is about to complete the weighing, resulting in errors in the proportioning.

Method used

The design employs a combination of a support plate, a mixing drum, a sliding plate, a weighing instrument body, a baffle, and a turntable. The raw materials are guided and dispersed around the holes by the inclined drum. When the weighing instrument measures the weight, the turntable and the holes of the baffle are misaligned, and the raw materials slowly slide down to gradually reach the required weight, thus reducing errors.

Benefits of technology

This design reduces errors in the expansion agent ratio and enables more precise weighing control.
