The eccentric axis is fixed to the frame; the eccentric part is attached with an eccentric sleeve; the eccentric sleeve is connected to the mould vibrating system through the connecting rod; the eccentric axis and the eccentric sleeve are attached with a speed reducing device and they are connected to each other through the driving axis; in addn. to the driving axises, a by-pass transmitting device is attached; either the driving axis or the by-pass transmitting device is connected to the driving source, and the eccentric axis and the eccentric sleeve are made to rotate at different speeds by the driving source through the by-pass transmitting device; and thus the vibration width of the connecting rod is changed. |
