Can find out from feeder constructional drawing of the present invention (Fig. 1), when base 7 during with the electromagnetic exciter vibration in phase, armature 16 and electromagnet each instantaneous will vibration in phase.At this moment, the air gap between armature 16 and the electromagnet core 14 will be less than the air gap of two plastid feeder armature and iron core among Fig. 3, because the minimum value of air gap and aviation value are very approaching.Can find out by Fig. 4; There is a balance position L5 in the armature displacement; There is a balance position L4 in the displacement of electromagnet core 14, and there is a balance position L3 in the hopper displacement, and the instantaneous length of air gap equals displacement, electromagnet displacement and the air gap mean distance sum of armature.When base 7 with the vibration excitor homophase and when amplitude is much at one arranged, then the instantaneous distance of air gap will be basicly stable, minimal air gap distance no better than, there is very much progress in more traditional two plastid system.From Fig. 3, can see; There is a balance position L2 in the armature displacement, and there is a balance position L1 in the displacement of electromagnet core, though the minimal air gap of two plastids is littler than the minimal air gap of three plastids; But average air gap is much larger than the average air gap of three plastids; Have proportional relation because drive the feeder power demand with average gas length, so compare with traditional two plastid system, this three plastids system can reduce the machine run power demand significantly.
Can find out from equation (8); Armature 16 can change through the rigidity
of adjustment hopper assembly quality
and the laminated spring I 5 that links to each other with hopper 1 with the vibration phase angle of electromagnet; Spring stiffness can realize that the hopper assembly quality then can be realized through the quality that changes counterweight 2 through the quantity that changes laminated spring I 5.
