Abstract
A mixing apparatus for pulverulent materials includes guide rods carrying a pair of opposed pressure plates having centers aligned along a common axis of rotation. A tubular frame encloses a three-dimensional volume disposed about said guide rods and pressure plates to shield the guide rods and pressure plates from inadvertent contact, and to mount an electric motor. The pressure plates are locked in position by a transmission shaft which is geared to a lead screw which engages the pressure plates.
Claims16
Mixing apparatus for pulverulent materials having a forward end for loading items to be mixed and a rearward end, comprising:
- guide rod means extending in a first plane;
- first rotating means for rotating the guide rod means in the first plane;
- a pair of opposed pressure plates having centers;
- slidable mounting means carried by said guide rod means for cantilever mounting of the pressure plates so as to align said pressure plates along a common axis generally parallel to said first plane and passing generally through the centers of the pressure plates, and so as to mount said pressure plates for sliding movement toward each other to engage and retain a container filled with the pulverulent materials during a mixing operation and said pressure plates movable away from each other to release the container;
- second rotating means for rotating said pressure plates and container about the common axis while said pressure plates, guide rod means and container are rotated in the first plane;
- electric motor means for driving at least one of said first and said second rotating means;
- operator means including screw shaft means threadingly engageable with said pressure plates for moving said pressure plates toward and away from each other as said screw shaft means is rotated in opposite directions, and a transmission shaft for rotational drive of said screw shaft means;
- and
- pressure plate locking means engageable with said transmission shaft to prevent rotation of said screw shaft means to lock said pressure plates in a desired position, said pressure plate locking means including a locking plate keyed to said transmission shaft for movement along a central axis of said transmission shaft between a locked position preventing rotation of said transmission shaft and an unlocked position where said transmission shaft is free to rotate.
