The utility model relates to the field of
paperboard processing, and discloses a slitting device for
paperboard processing, which comprises a
workbench, slitting equipment is arranged on the upper surface of the
workbench, a rotating shaft is rotatably mounted between the front end and the rear end of the inner wall of the slitting equipment, and a driving motor is mounted at one end of the rotating shaft extending out of the slitting equipment;
cutting blades are installed on the two side portions of the outer surface of the rotating shaft, supporting discs are welded to the positions, close to the two side portions of the
cutting blades, of the outer surface of the rotating shaft, a containing groove is formed in one side of the outer surface of each supporting disc, an elastic sleeve
gasket is arranged on the portion, located in the containing groove, of the outer surface of each supporting disc in a sleeving mode, and a supporting mechanism is further arranged in each supporting disc. According to the
paperboard slitting device, the slitting position of a paperboard is pressed through the elastic sleeve
gasket, so that the effect of conveniently limiting and supporting the paperboard in the
cutting process is achieved, the regularity of the slitting position of the paperboard is improved, the problem of edge
curling caused by the hollow interior of the paperboard in the slitting process is solved, and the attractiveness of the slit paperboard is improved.
