The Operation Process of Vibrating Feeder


     The Vibrating feeder consists of the complete flexible system of two-particle orientation forced vibration, and the whole system works at the low critical resonance state. It mainly takes use of electric magnetic exciter to make reciprocating vibration so as to drive material to move. Material is on the feeding body supported by main vibrating spring, gab bit combines with main vibrating spring of the cell body, and then loop is wrapped on the iron core. Through half-wave rectifier, unindirectional pulsating current flows in the loop, therefore electromagnet corresponding produces pulse-electromagnetic force (Figure 2(b)). In the positive half circle of AC, pulsating current flows through the loop which creates pulsating electromagnetic suction between iron core and gab bit. Under the power of the suction, cell body moves backward, and the main spring of exciter deforms so as to store potential energy; in the negative half circle of AC, there is no current in the loop, the electromagnetic force disappears, and the iron core is separated with electromagnet by the spring force which drives the silo to move forward, and then the silo does continuously reciprocating vibrating with the AC frequency.
