Ecoo JY 744 Four Color Offset Printing Machine

JY 744

 

The machine incorporates a CC-LINK technology bus module from Mitsubishi. Its double-diameter impression cylinder and transfer drum effectively reduce sheet transfer between print units. Moreover, the plate cylinder allows adjustments in circumferential, lateral, and diagonal directions.

 

1. The semi-APC (Automatic Plate Changer) reduces make-ready time.
2. Presets paper thickness for various types of paper and automatically adjusts printing pressure in each unit quickly and synchronously.
3. Non-stop feeder allows pile changes at production speed, saving time for thick paper and long-run jobs offline.
4. Equipped with a CC-LINK technological bus module from Mitsubishi.
5. Double-diameter impression cylinder and transfer drum minimize sheet take-over between print units.
6. Plate cylinder adjustable in circumferential, lateral, and diagonal directions.
7. Five rollers on the plate cylinder, with an intermediate roller in the alcoholic damping system to eliminate "ghost" images, achieve quick ink-water balance and reduce paper consumption.
8. Features 23 zones in the split (staggered) ductor.

- Utilizes a conjugated cam and a forwarding mechanism controlled by a linear guide rail for increased machine speed and stability.
- Features a rotary valve with patented technology for automatic paper dust cleaning, minimizing faults.

 

- The frame and base are cast integrally for robust construction.
- High-frequency quenching of gears ensures precise transmission.
- Helical gears with a high overlap coefficient minimize noise during operation.

 

- Stainless steel thermal spraying on the surfaces of impression and plate cylinders enhances press lifespan.
- Dynamic balance design minimizes vibration during printing operations.

 

- The press memory or job memory card (disk) stores the current job's settings, allowing for easy transfer to the press. During printing, preset values for the next job can be entered into the press memory or saved to disk.
- Supports CIP3/CIP4 standards for streamlined job data exchange and integration.

Pneumatic Clamp Bar, Tool-Free Plate Change:
- The clamp bar tension is adjusted using imported hoses and disc springs, enhancing operational flexibility.
- Cylinder corners are monitored by high-precision encoders. Plates are automatically installed and removed by the program, accommodating both long and short-print job requirements.
- The separated tail of the clamp bar ensures smoother paper handling.

 

-Every ink key in every unit can be set by the console.

-Ink amount can be displayed in digital and can be

 

- High-strength steel pads, quenched for durability, offer extended lifespan and convenient replacement.
- Wear-resistant soft pads ensure stable paper handling and precise paper transmission.
- Precision needle roller bearings and opening bearings enhance the stability of the gripper system.

- Gear-driven mechanism allows for automatic feedback of cylinder distance adjustments to the screen via a potentiometer.
- Driven by a permanent magnetic generator, ensuring stable printing pressure with robust torsion and self-locking capabilities.
- Conveniently input paper thickness directly on the screen for ease of use and accuracy.

- Utilizes an imported air pump with a large volume capacity.
- Automatically adjusts to accommodate all paper types and sizes, facilitating quick and easy paper format changes.
- Includes an ultrasonic double-sheet detector for enhanced cylinder protection.
