摘　　要：针对小计量称重配料过程中人工配料效率低、精度低的问题,对小计量称重配料系统的电磁振动供电电压、落料口高度和出料口大小方面进行了研究,提出了一种自动称重配料系统。通过称重配料实验平台,得出了电磁振动供电电压、落料口高度和出料口大小3个参数的实验数据,利用田口正交实验对称重系统的这三个参数进行了望目特性分析,获得了影响称重精度的因子贡献率以及因子间的交互作用。研究结果表明,田口正交实验法在材料颗粒较均匀的条件下可以优化称重配料系统参数,提高了计量准确度,为小计量称重配料系统的设计提供了参考依据。Aiming at the problems of low efficiency and precision of small-metering weighing and batching by manual work, the power supplyvoltage of electromagnetic vibration, the blanking opening height and the discharge port size were studied, and an automatic weighing andbatching device was proposed. The experimental data of the power supply voltage of electromagnetic vibration, the blanking opening heightand the discharge port size were gained by weighing and batching platform. The targeting being best of taguchi orthogonal experiment was a-dopted for analyzing the structural parameters of the weighing system. The contribution factors that affect weighing accuracy were calculatedand the interaction factors were obtained. The resuhs indicate that tagnchi orthogonal experiment method can optimize the parameters of weig-hing batching system to improve measurement accuracy under the condition of uniform material particles and provide a design reference forsmall measurement weighing batehing system.
