Abstract:

A novel vertical driven piezoelectric feeder was designed using the micrometric displacement and the big output force of the piezoceramic. The working principle was analyzed and the system dynamical model was built. Theoretical analysis confirmed the system vibration model, amplitude, natural frequency and the material movement. The distribution curve of natural frequency and the relation curve between amplitude and conveying speed were obtained through the prototype and experiment testing. The results indicate that the best working frequency of the prototype is 195 Hz, the amplitude of slide transport is between 17 μm and 27 μm and the speed can reach 123.5 mm/s, the amplitude of casting delivery is between 27 μm and 32 μm and the speed can reach 140.5 mm/s. In comparison with the same model cantilever piezoelectric feeder, the prototype of the novel feeder has better performance and smaller structure space and can satisfy industry requirements.
