摘要
基于压电驱动的原理,本文对高频低幅的振动给料技术进行了探索,研制出一种具有长环形输送振子的行波型超声物料输送装置的模型样机。对超声物料输送装置的模型样机进行了输送能力的实验研究,测试结果表明超声物料输送装置的输送速率可达120 mm/s,并可在一定范围内通过变频或变压调整。该输送装置具有结构简单、控制精度高和无噪声等优点,能实现微小块体物料的短距离输送或给料。
Based on the principle of piezoelectric drive, we make an explorative study of a novel feeding device with vibration of high frequency and low amplitude. Its prototype machine we develop has a ring-shaped feeding vibrator and uses ultrasound of traveling waves. Its feeding capability was studied experimentally. The experimental results show that its feeding velocity reaches 120 mm/s and can be adjusted by regulating the frequency or voltage of the feeding device. The ultrasonic feeding device can carry or feed millimeter-size solid objects because it has a simple structure, high precision for control and no noise.
