When the electromagnetic vibration feeding device starts to operate, when the pulse current is in a positive half period, the vibration material tray 4 moves downwards and is driven by the link mechanism 6 to rotate clockwise, the downward acceleration of the vibration material tray 4 is larger than the gravity acceleration of the material, the material leaves the spiral track 41, and the material moves anticlockwise relative to the vibration material tray 4; when the pulse current is in a negative half period, the vibration material tray 4 moves upwards and rotates anticlockwise along with the connecting rod mechanism 6, acceleration generated by the vibration material tray 4 can enable materials to be tightly attached to the spiral track 41, and the spiral track 41 drives the materials to move anticlockwise under the action of friction force. So that with the vibration frequency cyclically starting movement the material will move counter-clockwise with the spiral track 41 and be transported to the discharge opening 42 at the top of the vibrating tray 4.
