[0027] The cutting box 2 is a shell with a transparent front side and a bottom. A cutting cylinder 4 is provided on the top of the cutting box 2. A cutting knife 6 is installed on the telescopic end of the cutting cylinder 4 through a mounting plate 7. A lower pressure plate 5 is also provided on the mounting plate 7 for pressing the flap 14 to flip. The lower pressure plate 5 is arranged on the front side of the cutting knife 6. The bottom end of the lower pressure plate 5 is lower than the bottom end of the cutting knife 6 in horizontal height. During the processing, the lower pressure plate 5 first contacts the flap 14 and drives the flap 14 to flip to avoid affecting the collection of waste. The cutting cylinder 4 is connected to the PLC control unit 16.

[0028] In order to prevent the staff from accidentally touching the flap 14, causing it to flip over and affecting the paper feeding operation, the chassis 1 is also provided with a smart lock 17 supporting the flap 14, and a proximity switch 9 for controlling the opening and closing of the smart lock 17 is also provided between the lower pressure plate 5 and the cutting box 2. The smart lock 17 and the proximity switch 9 are connected to the PLC control unit 16. When the proximity switch 9 is disconnected, the smart lock 17 drives the lock tongue to retract, thereby releasing the limit on the flap 14.

[0029] A touch screen 13 is also provided on the loading area of ​​the chassis 1. The touch screen 13 can be used to control the operation of the pre-pressing cylinder 3, the cutting cylinder 4 and the motor 22. A starting switch 11 for controlling the operation of the cutting cylinder 4 is also provided on the front side of the chassis 1. Two groups of starting switches 11 are provided. The two groups of starting switches 11 need to be started at the same time to control the operation of the cutting cylinder 4, thereby increasing the safety of the device. The touch screen 13 and the starting switch 11 are connected to the PLC control unit 16.

[0030] The cutting box 2 is also provided with a pre-pressing cylinder 3, the telescopic end of the pre-pressing cylinder 3 is located inside the cutting box 2, and the telescopic end of the pre-pressing cylinder 3 is connected with a pre-pressing plate 8 for pre-pressing the paper to be cut. Before cutting the paper, the pre-pressing plate 8 contacts the paper to be cut and presses the paper. The pre-pressing cylinder 3 is connected to the PLC control unit 16.

[0031] The cutting box 2 is also provided with a support plate 21, and the support plate 21 is provided with two groups. The two groups of support plates 21 are respectively provided with a lead screw 23 and a slide rod 25. The slide rod 25 is slidably connected with an adjustment plate 24, and the adjustment plate 24 is provided with a threaded hole engaged with the lead screw 23. The lead screw 23 is driven by a motor 22, and the position of the adjustment plate 24 in the cutting box 2 is adjusted. In order to adapt to the size of paper cutting, the motor 22 is connected to the PLC control unit 16.

[0032] Working principle of the utility model: when using, the device is first connected to electricity, and the position relationship of the adjustment plate 24 in the cutting box 2 is adjusted according to the size of the paper to be cut, and the motor 22 is controlled to rotate through the touch screen 13 and the PLC control unit 16, which drives the lead screw 23 to rotate, and the lead screw 23 is engaged with the threaded hole on the adjustment plate 24, so as to drive the adjustment plate 24 to move in the cutting box 2, thereby realizing the adjustment of the size of the cut paper;

[0033] After the adjustment is completed, the paper to be cut is placed in the cutting box 2 so that one end of it is in contact with the adjusting plate 24. The staff member's two hands press the two starting switches 11 on the chassis 1 at the same time, first controlling the pre-pressing cylinder 3 to work, driving the pre-pressing plate 8 to move downward, and pre-pressing the paper to be cut to a limit position, and then controlling the cutting cylinder 4 to work, driving the mounting plate 7 to move downward, driving the cutting knife 6 and the lower pressure plate 5 to move downward, and when the lower pressure plate 5 moves downward, the proximity switch 9 between the cutting box 2 is disconnected, and the lock tongue of the smart lock 17 is controlled to retract, releasing the support for the flap 14. At this time, the flap 14 is still in a horizontal state under the elastic force of the torsion spring, and the cutting knife 6 and the lower pressure plate 5 continue to move downward. The bottom end is lower than the bottom end of the cutting knife 6. Before the cutting knife 6 contacts the paper to be cut, the lower pressure plate 5 contacts the flap 14 first, and presses the flap 14 downward to rotate around the hinge with the chassis 1. The torsion spring accumulates force, so that a gap appears between the flap 14 and the chassis 1. The cutting knife 6 continues to move downward to cut the paper. The cut waste falls into the collection frame 15 in the chassis 1 through the gap, completing the cutting of the paper. The cutting cylinder 4 drives the mounting plate 7 to reset. The flap 14 is in a horizontal state under the elastic force of the torsion spring. When the lower pressure plate 5 is connected to the proximity switch 9 on the cutting box 2, the lock tongue of the smart lock 17 extends out to limit the flap 14. After the reset of each component is completed, the staff can take out the cut paper.
