Design and test of a multi-edge toothed cutting device for membrane-impurity mixed material

As the existing residual film crushing device in Xinjiang cannot directly crush membrane-impurity mixed material, by analyzing compressive and cutting force characteristics of material layer cotton stalk, conditions materials were obtained, method was determined. A multi-edge toothed cutters created, a built. It preliminarily determined that number teeth 8, clearance between tooth fixed blade 3 mm, speed high-speed cutter 800 r/min, difference high- low-speed –300 r/min. Test results show ratio to total sampling mass (2.22±0.3)%, (19.19±2.02)%, (58.94±3.19)% (20.65±2.05)%, respectively, when maximum outer profile size range [0,20) [20,100) [100,500) mm [500,~) mm. The stalks with lengths [0,50) [50,100) [100,~) accounted for (32.57±1.5)%, (27.77±1.3)% (39.66±1.75)%, power consumption (85.41±15.63) kJ. test can provide basis subsequent technology, as well some guidance separation it.
