Automatic Four Color A1 Offset Printer For Books

Four Color Offset Printing Machine

Product Description

Introducction

JY41050 folio four-color offset printing machine features short water and ink roller distances to enable a more economical printing with low, or no, alcohol. Suitable for ultra-wide format and 0.8 mm thick paper, 13,000 sheets per hour for high production packaging printing.

Features

1. Vacuum suction variable speed belt type paper feeding, paper feeding synchronous adjustment mechanism;
2. Conjugate cam driven downward swinging paper transfer mechanism;
3. The pneumatic side gauge, front gauge, and paper pressing tongue are separated, and the front gauge moves up and down in a reciprocating motion, which can be adjusted as a whole in front, back, and tilt. The paper pressing tongue swings in a fixed axis;
4. One line paper roller, printing roller arranged at seven o'clock, with shoulder iron printing;
5. The adjustment of the biting force and biting time of the embossing drum is completed by the torsion spring rod and eccentric bearing;
6. Air cushion guide plate paper feeding;
7. Remote control partition ink hopper, controlled by 32 ink spoon motors, can adjust and change the ink supply amount on the central console;
8. The short ink path system with 08.16 ink rollers ensures fast ink control reaction speed, while increasing the diameter of the ink rollers to ensure a certain amount of ink storage;
9. The ink path system has an automatic separation function, which can quickly achieve ink water balance during the printing process;
10. The intermediate roller can choose different working methods based on the size of printing ink volume;
11. The paper buffer adopts a separate motor drive, frequency converter control, and stepless speed regulation method. The appropriate working speed can be selected according to the actual printing conditions;
12. Optional water roller speed change device. After the function is activated, dirt such as ink and paper fuzz are removed from the printing plate under the effect of speed difference.

Specification

Machine Spare Parts

1. Configure an ink control sample viewing platform, allowing users to adjust ink color online in real-time based on the print sample
2. A file that can store thousands of ink color settings for prints, allowing for easy reproduction of previous tones, greatly reducing the technical requirements for printing technicians
3. Support CIP3/CIP4 processes and communication protocols

 

 

Separate front gripper:

1. The lower front gauge adopts a straight up and down motion and is separated from the paper pressing action, resulting in long paper stabilization time and high paper positioning accuracy
2. The paper pressing mechanism is equipped with rollers, effectively reducing scratches on the back of the paper
3. Five fiber optic detection devices are arranged at the front gauge to quickly identify and lock paper delivery faults such as skewness, over tension, and early arrival

 

 

Three-roll alcohol dampening system:

1. Adopting a three roll short waterway design, the water supply is faster and the alcohol consumption is low
2. The water bucket roller is directly driven by a frequency conversion synchronous motor, and is strongly driven by the plate water roller to meet the changes in the amount of water fed to different prints
3. The water roller can be easily cleaned through program control, reducing the labor intensity of operators

 

 

Feeder:
Feeder with rotary air valve - The feeder mechanism pairs a cam with a linear guide for smooth running. The patented rotary air valve automatically removes impurities on the paper, which helps reduce the failure rate. The upper and lower limits of the paper pile are protected by the feeder

 

 

Transmission system:
Transmission system - a large modulus helical gear accurately maintains transmissions and reduces noise. The lay-on roller is designed for stability and durability with high-speed printing

 

 

Air vacuum paper feeding technology:
1. Throughout the printing process, the part facing the image and text is transmitted and received using an axial flow fan controlled air guide plate to generate air cushion paper support, which can be adjusted according to the texture of the printed material to minimize scratches on the paper
2. Made of high-quality stainless steel molding
3. Air ducts and hole positions simulate the movement of airflow and paper, scientifically calculate and arrange them

 

 

Touch screen
1. Adopting fieldbus control technology, touch based operation, simple and clear.
2. Humanized work interface, integrated adjustment and production management functions.
3. High resolution, fast response speed, and long service life.
