Multiple rotating shafts are installed inside the conveyor trough, and a conveyor belt 5 is sleeved between two rotating shafts. A servo motor for driving one of the rotating shafts is provided on one side inside the base 2. Multiple roller grooves are longitudinally opened on both sides of the top of the base 2, and rollers 6 are rotatably installed in each roller groove. The front and rear ends of the connecting plate 4 are provided with mounting ports, and electric push rods 12 are installed in each mounting port. The top of the telescopic end of the electric push rod 12 is fixedly connected to the outer wall of the baffle 3. Multiple pressure plates 13 are equidistantly arranged on the outer surface of the transmission belt 7. The pressure plates 13 are rubber strips, which facilitate the limiting of paper.

[0019] In this utility model, the cutting assembly includes a blade 9 horizontally positioned above the rear end of the base 2 and pressure shafts 10 located on the base 2 in front of and behind the blade 9. Hydraulic cylinders 8 are located on both sides of the rear end of the top of the worktable 1. One hydraulic cylinder 8 has a placement frame 15 mounted on its telescopic end, and the other hydraulic cylinder 8 has a limiting seat 16 mounted on its telescopic end. One end of the blade 9 is mounted on the limiting seat 16 via a pin, and the other end of the blade 9 is fixed in the slot of the placement frame 15 via bolts. Both ends of the two pressure shafts 10 are rotatably connected to bearing seats 14, which are fixedly mounted on the top surface of the base 2. Two mounting slots that mate with the pressure shafts 10 are provided on the top surface of the base 2.

[0020] Working principle: When using this utility model, firstly, the servo motor in the conveyor belt 5 is started to make the conveyor belt 5 start operating. Then, the micro motor is started to drive the roller shaft 11 to rotate. The roller shaft 11 drives the transmission belt 7 to drive in the same direction as the conveyor belt 5. Then, according to the width of the paper bag, the electric push rod 12 is started to drive the baffle 3 to move relative to each other on the top of the base 2, so that the transmission belt 7 can be adjusted laterally according to the width of the paper bag for edge pressing operation. Then, the paper to be cut is placed in the gap between the transmission belt 7 and the base 2. The paper is limited by the pressure plate 13 to prevent the paper from shifting. Then, the paper is conveyed to the inner pressure shaft 10 by the conveyor belt 5 and the roller 6. After the paper passes through the inner pressure shaft 10 and the auxiliary shaft on the surface of the base 2, it arrives flat directly below the blade 9. The hydraulic cylinder 8 adjusts the blade 9 to a suitable height and then cuts the paper. The cut paper is then output flatly through the outer pressure shaft 10.
