Zusammenfassung: | The invention discloses an edge damage preventing device for a cutter of a plastic grain cutting machine and belongs to the technical field of grain cutting machine auxiliary devices. The edge damage preventing device comprises an extruder, a cooling device and the grain cutting machine. The cooling device is located between the extruder and the grain cutting machine. The extruder, the cooling device and the grain cutting machine are connected through a material strip. When the material strip is mixed with iron scraps, a magnetic board attracts the material strip, connecting springs elongate to enable a first conductive block to be separated from a second conductive block, accordingly, an electromagnet switch is switched off, an iron block moves leftward under the effect of a reset spring and a T-shaped rod to be separated from a U-shaped seat, a power beam still moves under the control effect of the grain cutting machine, the cutter can move up and down along guide rails under the effect of sliding blocks, a |
