Abstract
A screw extruder has a feed roller which is parallel to and spaced laterally from the screw,a hopper feeds the material to be extruded to the screw and feed roller and to the space between them.A knife scrapes material from the feed roller to keep it clear.In one embodiment,the knife is pivotally supported by a knife holder disposed below the feed roller and is pulled against the feed roller by a spring-loaded link which is pivotally attached to a median portion of the blade.In another embodiment,the knife is a flexible spring blade.A protuberance on a knife-holding plate limits flexing of the blade by pressure of material in the space between the screw and the feed roller.In a further embodiment,a photo-cell scans a rear side of the feed roller and controls a servo-motor for drawing the knife against the feed roller.
FIELD OF INVENTION
The invention relates to a screw extruder in the feed hopper of which there is arranged a feed roller on the circumference of which lies the cutting edge of a knife which is pressed against the surface of the feed roller by the force of a spring.
