Design of a New Piezoelectric Vibrating Feeder

Abstract:

With two upper and nether piezoelectric vibrators to provide excitation in the same time, vertical double driven piezoelectric feeder (vertical double driven feeder for short in the paper) has smaller piezoelectric ceramics (PZT), and lower driving voltage to prolong the lifetime of the PZT, meanwhile, its carrying capacity gets stronger, compared with vertical single driven piezoelectric feeder (vertical single driven feeder for short in the paper). Vibration analysis was carried out on the feeder system, and the affection factors on the system natural frequency and feeder tray amplitude were received. Based on the modal analysis, the system theoretical resonant frequency was got as 135.95Hz. In the end, the prototype was tested to analyze the relationships among the feeding speed, feeder tray amplitude, driving voltage and driving frequency.
