[0002] A die-cutting machine, also known as a cutting machine, a beer machine, and a numerical control stamping machine, is mainly used for die-cutting, indentation, and hot stamping operations on some non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronics, mobile phone pads, etc. It is an important device for packaging processing and forming. By using steel knives, metal molds, steel wires, or die-cutting knives to apply a certain pressure to the material, the cardboard or other materials are cut into corresponding shapes.

[0003] When the die-cutting machine is in processing, it is necessary to make the die-cutting knives on the same plane to avoid imbalance, which may cause the inability to effectively cut and separate the products during the cutting process, affecting production efficiency and product progress. Therefore, before and during the use of the die-cutting knives, it is necessary to check the flatness of the cutting knives to avoid unevenness and affect subsequent production and processing. However, when adjusting the flatness of the existing cutting knives, the whole needs to be loosened and then leveled so that the cutting knives can be on the same plane. Adjusting in this way requires the cooperation of multiple people and takes a lot of time and effort, resulting in an increase in the production cost of the enterprise.
