[0002] Paper packaging boxes are a commonly used packaging material. When automotive parts leave the factory, they are placed in corresponding packaging boxes for packaging.

[0003] In the current existing technology, paper packaging boxes are generally printed with corresponding patterns. In order to ensure the quality of printing, certain excess corners are reserved on the cardboard during printing. These excess corners need to be cut off later. Workers generally need to use a cardboard cutting machine to cut the corners of the cardboard. The cardboard cutting machine is generally composed of a workbench, a motor and a paper cutter. The motor is installed on the workbench and relies on the motor to drive the paper cutter to rotate at high speed. The worker moves the cardboard on the workbench to complete the cutting of the cardboard.

[0004] During work, in order to improve work efficiency, the staff will stack multiple cardboards together and then cut them together. However, when multiple cardboards are stacked together, the positions of the multiple layers of cardboards will be offset to a certain extent, and under the action of the friction force of the fit, it is difficult to align them, which will affect the accuracy of subsequent cutting. Therefore, a paper packaging box cutting device is proposed to address the above problems. Utility Model Content
