Description

[0002] The function of packaging boxes is to ensure the safety of products during transportation and enhance the quality of products. During the production and processing of packaging boxes, cardboard needs to be cut. With the development of society and the improvement of people's living standards, higher requirements are placed on the aesthetics of packaging boxes, especially satin packaging boxes used as high-end packaging boxes. There is an urgent need for a seamless processing technology to make the processed satin packaging boxes more beautiful.

[0003] For example, the prior art CN207874324U discloses a reciprocating circular saw cardboard cutting machine, in which the cardboard is repeatedly cut by a cutting blade. During the cutting process, the cutting size of the cardboard cannot be controlled, and after the cutting is completed, the cut cardboard needs to be picked up manually.

[0114] During the process of cutting the cardboard, the cutting unit cooperates with the offset unit, and the offset unit drives the cutting 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] Wherein, G is the thickness of the cutting blade, 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 blade; f2 is the sharpness index of the cutting blade; f3 is the thickness coefficient of the cutting blade; and f4 is the cutting angle coefficient of the cutting blade.

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