Feeder for powder or granule dispensor, comprises motor and eccentric driven transverse oscillating plates, a loading funnel with sheath for feed screw and a rim which rests on dispensor frame

摘要

The dispensor uses an elastomeric moulded feeder (12) which has oblong horizontal sections diminishing to a sheath (20) at the bottom for a dosing monoscrew. The feeder (12) is supported by a rim (18) which rests on the dispensor frame and is in contact with horizontal plates (24,26,28). The plates are made to oscillate by a motor (52) which drives them through a belt (46), a pulley (44) shafts (36,42) and eccentric cams
