Quick-change Drop Hoppers. Rolls have thick chrome plating on the face. Each hopper incorporates an adjustable slide gate.
The clean-out auger is used to remove remaining granules after the new color has started dropping onto the sheet. Color change can be made without stopping the production line.
Adjustable Slide Gates: The adjustable slide gate shafts are connected to lever arms. The lever arms in turn are linked together and connected to a linear actuator.
Blender Shifting Mechanism: Pneumatic cylinders shift the complete upper hopper during a color change.
Continuous and Auxiliary Backfall Hoppers: The continuous drop hopper is used during color change to allow the operator to clear the Back-fall hopper of the old color and fill it with the new color. A screen mounted on top of the hopper helps to filter out any large contaminants that may try to enter.
