A cutting docking groove 5 is opened in the middle of the upper surface of the workbench 1. The cutting docking groove 5 corresponds to the left and right positions of the infrared locator 8. When cutting operation is required, The packaging box paperboard can be manually picked up, and then according to the primary positioning of the scale line 10, the packaging box paperboard is extended to the lower end of the gantry 2. At this time, the single-chip microcomputer 9 can be regulated, and the infrared positioning instrument 8 and the detection camera 11 are operated at the same time. The infrared positioning instrument 8 sends an infrared positioning line to irradiate the upper surface of the packaging box paperboard. At this time, the infrared positioning line is the position of the cutting docking groove 5. At this time, the detection camera 11 returns the cutting picture of the irradiated packaging box paperboard to the single-chip microcomputer 9 in real time. At this time, the position of the packaging box paperboard can be manually adjusted to adjust the cutting position. When the positioning is accurate, the external air pump can be adjusted, and the cutting cylinder 35 is operated. The cutting cylinder 35 is operated, and the telescopic end of the cutting cylinder 35 is extended, and then the cutting frame 34 is moved downward to the specified position. At this time, the cutting knife 36 extends into the inside of the cutting docking groove 5 to complete the cutting of the packaging box paperboard.

During this process, the rear side pressing plate 4 first presses the paper material of the packaging box, and then the rotating frame 61 will rotate about the axis of the rotating shaft, thereby driving the flattening roller 62 to press the upper surface of the paper material of the packaging box. The downward force of the cutting frame 34 is partially overcome by the telescopic spring 67. At the same time, the flattening roller 62 presses the paper material of the packaging box tightly to flatten it. Finally, the cutting knife 36 extends into the cutting docking groove 5 to complete the cutting operation of the packaging box. Then the cutting frame 34 is reset, and the generated waste is discharged out of the cutting machine along the hopper 7.

[0029] The working principle of a paper cutter for packaging box processing provided by the utility model is as follows: when cutting operation is required, the packaging box paperboard can be picked up manually, and then the packaging box paperboard can be extended to the lower end of the gantry 2 according to the primary positioning of the scale line 10. At this time, the single-chip microcomputer 9 can be regulated, and the infrared positioning instrument 8 and the detection camera 11 can be operated at the same time. The infrared positioning instrument 8 sends out an infrared positioning line to irradiate the upper surface of the packaging box paperboard. At this time, the infrared positioning line is the position of the cutting docking groove 5. At this time, the detection camera 11 returns the cutting picture of the irradiated packaging box paperboard to the single-chip microcomputer 9 in real time. At this time, the position of the packaging box paperboard can be manually adjusted to adjust the cutting position. When the positioning is accurate, the external air pump can be adjusted, and the cutting cylinder 35 can be operated. The cutting cylinder 35 rotates, the telescopic end of the cutting cylinder 35 extends, and then moves the cutting frame 34 downward to the specified position. At this time, the cutting knife 36 extends into the cutting docking groove 5 to complete the cutting of the packaging box paperboard. In this process, the rear side pressing piece 4 first presses the packaging box paperboard, and then the rotating frame 61 rotates about the axis of the rotating shaft, thereby driving the flattening roller 62 to press the upper surface of the packaging box paperboard. The downward force of the cutting frame 34 is partially overcome by the telescopic spring 67. At the same time, the flattening roller 62 presses the packaging box paperboard tightly to flatten it. Finally, the cutting knife 36 extends into the cutting docking groove 5 to complete the cutting operation of the packaging box. Then the cutting frame 34 is reset, and the generated waste is discharged out of the cutting machine along the hopper 7.
