[0002] ‌Circular knife die cutting‌ is a process of cutting materials with a circular knife, mainly used in packaging, printing, electronics, medical and other fields. The circular knife die cutting machine achieves the effect of continuous rolling die cutting through gear transmission, usually including a driving wheel with gears, driving a steel roller with gears, and then driving the circular knife. The material is die-cut into the required shape between the circular knife and the steel roller‌.

[0003] The inventor discovered the following defects during the operation of the specific embodiment: Most of the equipment for cutting coils is circular die cutting. Since the coils are slightly bent, it is easy to cause problems such as uneven cutting length and insufficient verticality of the cutting edge.

[0004] Moreover, the cost of circular die-cutting equipment is relatively high, and large-scale production is required to reduce the equipment investment cost.
