Abstract：Abstract：The basic requirement of powder metering in the application of engineering machinery and equipment is accurate measurement. It is necessary to ensure the stability of the measurement scale during the measurement process, in order to prevent deviations, which will directly affect the quality of the mixture. The central control system is designed by PLC. It can drive two motors at the same time. When one motor is driven, the material is dispersed to make it fall evenly, and the other is to transport the powder, which can effectively reduce the error. The batching process is refined into three parts: quick batching, slow batching, and fine batching. The weight signal is continuously transmitted to the central control system by the weighing sensor under the measuring case. At the end of the mission, the measuring case is turned 180° and the powder is poured out. Which can effectively improve the measurement accuracy. The measurement accuracy of this system is 99.92%.
