[0112] Where, [(A*B)*cosθ] is the deviation adjustment coefficient of the cutting knife’s oblique cutting;

[0113] The deviation value DE between the cutting path and the cutting path can be analyzed based on the image data collected by the recognition probe, such as further determining the deviation value based on the relationship between the position where the current cutting knife cuts the paperboard and the pixels of the cutting path. This is a technical means well known to those skilled in the art, and those skilled in the art can refer to relevant technical manuals to learn about the technology, so it will not be described in detail in this embodiment.

[0114] In the process of cutting the paperboard, the cutting unit cooperates with the offset unit, and the cutting unit is driven by the offset unit to cut at a cutting speed V, wherein the cutting speed V is calculated according to the following formula:

[0115] V=k·G 2 ·C

[0116] In the formula, G is the thickness of the cutting knife, k is the cutting adjustment index, C is the inherent cutting base, and its value satisfies C=f1+f2+f3+f4, wherein f1 is the blade thickness index of the cutting knife; f2 is the sharpness index of the cutting knife; f3 is the thickness coefficient of the cutting knife; f4 is the cutting angle coefficient of the cutting knife;

[0117] By controlling the cutting speed and the cutting deviation value, the cutting of the cardboard can be accurately controlled, thereby improving the accuracy of packaging box production.
