LC-B Series 1226 High-speed ​​water-based Printing And Die-cutting Machine

Machine Configuration and Technical Specifications

Overall Performance

1. The machine integrates the paper feeding unit, printing unit, and slotting unit. It can complete printing, creasing, slotting, cutting, and stacking for three- or five-layer corrugated paperboard in a single pass.
2. The transmission system uses a helical gear set for smooth, quiet operation and increased strength. All transmission shafts are made of 20CrMnTi alloy steel, precision-ground after carburizing and quenching. The entire structure is sealed and force-lubricated, ensuring long service life and high accuracy.
3. Each unit features an electric separation alarm system to ensure operational safety.
4. Each unit is pneumatically locked and equipped with a fixed mechanism for stable positioning.
5. All motors have automatic zero-return systems for alignment and speed stability.
6. The printing and slotting units are equipped with PLC and human-machine interface (HMI) for automatic control.
7. Bearings adopt NSK or other well-known brands to ensure durability and precision.
8. Equipped with adjustable feeding system to accommodate paper thickness variations.
9. The entire line is built with precision machining and rigorous quality testing to ensure accuracy and reliability.

Computer Control System

1. The paper feeding, printing, and slotting units all use a PLC + HMI operation interface.
2. Memory-zero function: automatically resets to zero after completion or reboot.
3. One-key registration and plate position memory allow fast and precise setup.
