A Piezoelectric Feeder with Magnetic Spring

Abstract:

Proposed a new type of piezoelectric feeder uses the magnet principle to change the vibration performance and the system resonance principle. The working principle of the piezoelectric feeder was analyzed, the kinetic model was established, and the main factor which affects the delivery performance of the resonant feeder was obtained by calculation, and then designed the prototype. The resonant frequency of the system obtained by the impedance analyzer, and the displacement magnification of the piezoelectric vibrator were obtained by using the laser displacement meter. Design the speed experiment device of the resonant feeder, obtained the influence of the magnetic spring gap on output speed. The experimental show that when the input voltage is 150v, the frequency is 140Hz and the magnetic spring gap is 8mm, the system achieved the desired working condition, the displacement magnification of the piezoelectric vibrator is about 2.46 times, the optimum speed is 80cm/min.
