Measurement order and procedure for determining the properties of a material to be extruded during the execution of a snail extrusion process

摘要

When measuring the properties of a material to be extruded during the extrusion process in an extruder (7), at least one extruder hook (4) is rotary and can be rotated in a housing (7) in a tube-shaped guide (5)AB connected. Material to be extruded (1) is fed to the tube-shaped guide (5) on one side of the forehead and is discharged as finished extruded material on one of these opposite sides (6). Along the longitudinal axis of the extruder hook (4) are several first sound converters (3)for the detection of sound waves, generated during the extrusion process as process noise by the extrusion process and/or by a second sound converter (5) positioned on the front of the tube-shaped conductor (2) into which a material to be extruded towards the longitudinal axis is conveyed by a kneecap space present in the tube-shaped conductor the extruder hook (4) are emitted, trained, positioned at predefined intervals at the wall of the tube-shaped guide (5) at measuring positions.
