[0002] In today's rapidly developing digital printing industry, with the continuous acceleration of printing speed and the steady increase in production efficiency, paper cutting devices, as a key component, are facing increasingly stringent requirements in terms of precision, speed, stability, and adaptability to different types of paper.

[0003] Firstly, existing digital printing press paper cutting devices tend to produce uneven paper cuts, significantly impacting the aesthetics and integrity of the printed materials. For example, simple mechanical cutters suffer from severe blade wear over time, resulting in inconsistent cutting quality. Furthermore, replacing these cutters is cumbersome and inconvenient. Secondly, existing digital printing press paper cutting devices have a low level of automation, requiring frequent manual intervention and adjustments during operation. This undoubtedly increases labor costs significantly and reduces overall production efficiency, failing to meet current demands. Utility Model Content

[0025] The mounting device 7 consists of a U-shaped plate 701, a fixed cylinder 702, a pull rod 703, a circular block 704, a spring 705, a first limiting post 706, a strip plate 707, and a second limiting post 708. The U-shaped plate 701 is fixedly installed at the bottom of the hydraulic rod 6. The fixed cylinder 702 is fixedly installed on the side of the U-shaped plate 701. The pull rod 703 is slidably installed inside the fixed cylinder 702. The circular block 704 is fixedly installed on the side of the pull rod 703.
