[0015] Figure 2 for Figure 1 Another perspective of the view. DETAILED DESCRIPTION

[0016] As shown in the figure, the rear cutting mechanism of the strip slitting machine disclosed in the utility model includes a feeding conveyor belt 2, a positioning plate 7 is arranged on one side of the feeding conveyor belt 2, and the positioning plate 7 is extended along the moving direction of the feeding conveyor belt 2. A guide assembly is arranged on the other side of the feeding conveyor belt 2. The guide assembly can guide the strips transported on the feeding conveyor belt 2 so that one side of the strip can be against the positioning plate 7. In this embodiment, the guide assembly includes a guide pressure wheel 4 arranged on the mounting frame 3, and the guide pressure wheel 4 is arranged obliquely toward the positioning plate 7. Furthermore, a locking block 5 is connected to the mounting frame 3, and a mounting rod 6 is passed through the locking block 5. By loosening the locking block 5, the mounting frame 3 can be controlled to move along the mounting rod 6, and then the spacing between the guide pressure wheel 4 and the positioning plate 7 is adjusted to adapt to the width of the mouth strip. A front traction roller group 8 is provided at the discharge end of the feeding conveyor belt 2, and a cutting knife assembly is provided at the discharge end of the front traction roller group 8. Specifically, the cutting knife assembly includes a cutting circular knife 13, and a knife wheel 15 is provided below the corresponding cutting circular knife 13. The knife wheel 15 is provided with an annular knife groove 14 that cooperates with the cutting circular knife 13. The knife wheel 15 is provided on a rotating shaft 16, and the rotating shaft 16 is connected to the output end of the driving motor.
