[0002] With the continuous progress of modern industrial manufacturing technology, die cutting technology is increasingly widely used in the processing of various products. As a key device for realizing precise cutting, indentation and other processes, the die cutting machine plays an important role in multiple industries such as packaging, printing, and electronic products. However, when facing diverse and personalized processing requirements, traditional die cutting machines often seem powerless, especially in terms of the adjustment of indentation angles, the flexibility of die cutting directions, and processing efficiency, there are obvious limitations.

[0003] In traditional die cutting processes, the adjustment of indentation angles usually requires replacing the entire set of dies or performing complex mechanical adjustments, which not only takes time and effort but also increases production costs. At the same time, traditional die cutting machines can often only achieve a single die cutting direction and cannot meet the requirements for multi-angle and multi-direction die cutting in modern product processing. These limitations have restricted the application scope and production efficiency of die cutting technology to a certain extent.

[0004] Therefore, those skilled in the art have provided a die cutting and indentation mechanism for a die cutting machine, which needs to be able to quickly and accurately adjust the indentation angle, support multi-angle die cutting operations at the same time, and can perform horizontal and vertical die cutting and indentation without replacing die cutting tools to solve the problems raised in the above background art.
