Abstract
Provided is a cutter shaft structure of a transverse cutter. Two ends of a mandrel (7) are fixedly mounted on a case (1) via an expansion sleeve (8). An aligning roller bearing is fixedly mounted on the mandrel (7). A roller bearing pedestal (5, 15) is fixedly disposed on the aligning roller bearing. The roller bearing pedestal and a roller (6, 17) are fixedly mounted. Roller rotation driving structures are disposed at two ends of the roller bearing pedestal (5, 15) and the roller (6, 17). A cutter rest and a cutter (10, 12) are arranged outside the roller (6, 17). The mandrel (7) is fixed without moving. The roller rotation driving structures drive the roller (6, 17) to rotate about the mandrel. According to the above structure, the mandrel is fixed and the cutter roller rotates, so that the moment of inertia is reduced, the weight of a cutter shaft is reduced, and then energy-saving effects are achieved. Meanwhile, a space between bearings is reduced, and the cutter shaft structure, stable in cutting during transverse cutting (W>=2200) of broad-width cardboards, exhibits substantial energy-saving effects.

Further, described roller rotary drive structure comprises driven tooth wheels and input gear axle, and described input gear axle is fixedly mounted on casing by eccentric bushing, and driven wheel and the driven gear assembly of input gear axle in casing closed.
More preferably, described driven tooth wheels comprise pinion stand, gear and tune gap gear, and described pinion stand is fixedly mounted on by screw on the end face of described roller bearing seats, adjust gap gear, gear and the fixed installation of described pinion stand.
More preferably, described pinion stand is by the excircle orientation of self-aligning roller bearing.
More preferably, described tune gap gear and gear are located by adjusting pin and pinion stand.
Said structure adopts mandrel to fix, and rotor cylinder rotates, thereby alleviated, rotates the amount of whipping and cutter shaft weight, thereby reach energy-saving effect, reduced the supporting spacing of bearings at both ends simultaneously, greatly improved cutter shaft rigidity, for wide cut cardboard crosscut W >=2200 o'clock, cut good stability, energy-saving effect is remarkable.
