The utility model discloses a double-working-station lengthwise cutting structure with an upper cutter and a lower cutter combined. The double-working-station lengthwise cutting structure comprises a machine frame, an upper cutter component and a lower cutter component are arranged on the machine frame, the upper cutter component and the lower cutter component share one variable frequency motor which is installed on a variable frequency motor fixing seat, an output shaft of the variable frequency motor is connected with a small motor belt pulley, the small motor belt pulley is connected with big transmission belt pulleys through a transmission synchronous belt, the big transmission belt pulleys are connected with a reversing spline shaft, the reversing spline shaft is connected with a transmission spline shaft through a reversing double-face synchronous belt, spline sleeve belt pulleys are arranged on the reversing spline shaft and the transmission spline shaft, the spline sleeve belt pulleys are connected with cutter disk belt pulleys through cutter disk transmission synchronous belts, and dividing and cutting blades are arranged on the cutter disk belt pulleys. The double-working-station lengthwise cutting structure with the upper cutter and the lower cutter combined lowers cost, reduces the equipment size, realizes non-speed-reduction of order changing in a high-speed production line, improves average speed and improves productivity.
