[0002] As the market demand for personalized and diversified printing products increases, printing companies need to flexibly respond to printing requirements of different specifications and sizes. The flexibility and adaptability of the cutting mechanism can meet the diverse needs of the market. Moreover, with the continuous development of printing technology, the cutting mechanism is also constantly improving, which has promoted technological innovation in the entire industry. Advanced cutting technologies, such as laser cutting or CNC cutting, are gradually being introduced to improve cutting accuracy and efficiency. The cutting mechanism is combined with other production links (such as printing, post-processing, etc.) to form an efficient production line. The smooth production process not only improves the overall efficiency, but also reduces the waiting time between each process.
