How do electromagnetic vibratory feeder works
Monday March-21 2022 15:59:35
The electromagnetic vibrating feeder is a relatively complete elastic system with two-particle directional forced vibration. The whole system works in a low critical resonance state. It mainly uses the electromagnetic vibrator to drive the tank body to vibrate back and forth at a certain inclination angle, so that the material moves along the tank.
By adjusting the parameters of the electromagnetic vibrator (power frequency, magnetic force, amplitude, etc.), the feeding amount can be adjusted freely, which can be used to automate the production process in the automatic control process.
Academic principle description:
The electromagnetic vibrating feeder is a relatively complete elastic system with two-particle directional forced vibration. The whole system works in a low critical resonance state. It mainly uses the electromagnetic vibrator to drive the tank body to vibrate back and forth at a certain inclination angle, so that the material moves along the tank. . Since the half-wave rectified unidirectional pulsating current flows through the coil, the electromagnet generates a corresponding pulsed electromagnetic force. In the positive half cycle of the alternating current, the pulsating current flows through the coil, and a pulsating electromagnetic attraction force is generated between the iron core and the armature, which makes the tank body move backward, and the main spring of the exciter is deformed to store potential energy; in the negative half cycle, There is no current in the coil, the electromagnetic force disappears, the armature is separated from the electromagnet under the action of the spring force, and the trough moves forward, so that the trough vibrates continuously at the frequency of the AC power supply.
