Machine d'impression flexographique FM-A multi-couleurs

Function Units

1.Unwinding Unit

• Unwinding method of single-unit air-expanding shaft for base paper feeding rack
• Loading method of convex key type air expanding shaft
• Rewinding uses magnetic powder brake and automatic tension control to achieve constant tension control.
• Early warning of material change (automatic warning of too small unwinding diameter)
• Paper breaking shutdown device
• Equipped with a rapid inflatable gun
• Deviation correction system: can automatically correct the position of paper; Detection method: edge checking
• Paper bonding platform, easy to operate
• Hydraulic loading and unloading device

2. Web Guide System

• Paper Splicing Table : with pneumatic paper holding device.
• Ball screw electric actuator
• Adopt the photoelectric sensor for web guide transmission
• Electronic web guide traction device. If there is any excursion in paper feeding,the system will have a constant and accurate adjustment
• Adopt closed loop control system to accurately detect the deviation and correct it
• Hard Anodization to the paper guide HV 800-1000
• Inspection:the edge
• Web Guide precision:±0.02mm

3. In-feed Tension Control Unit

• Use the double side pressure rubber roller to clutch and feed paper and to ensure the tension

4.Printing Units(shaft system)

• The machine double sides frame is made of overall alloy and cast iron, which improves the stable performance and durability of the press machine
• High precision ceramic anilox roll with micro-metric adjustment
• Reversed single doctor blade
• Anilox roll and printing cylinder separation and reunion pneumatically
• self-cleaning plate feature.The anilox and plate cylinders release alternately, transfering residual ink to the paper when machine stop, leaving the printing plates clean and minimizing the need of hand to clean the plates
• When press stops, the anilox roll continuous running. Hence avoiding permanent damage, which is caused by ink drying on the anilox surface

5. Drying Units

• Every printing unit has one separate drying unit
• High efficiency drying unit including infra red lamps, air blowing/suction system. Air intake adjustable, Air circulation design on the exhaust, the blower is adjustable
• Short wave infrared heating elements
• Natural air blowing assembly with exhaust fan

6. Video Web Inspection System

• Video is high efficiency and synchronous, can be moved left and right
• With 14 inch monitor one pc
• one stroboscope lamp
• It can be enlarged 18 times of image

7.Out Feed Tension Control System

• The rear tension unit is made of alloy and cast iron
• Use the double side pressure rubber to clutch and feed and to guarantee the stale tension

8.Rewinding Unit

• rewind unit 60’’(1524mm)capacity, with 3’’ shaft
• Hydraulic roll lift
• Web break sensor, automatically shut down when paper broken.

9. Automatic Lubricating System

• The gear’s automatic dampening system can adjust the lubricating time and ration
• When the dampening system breaks down or the lubrication is not enough, the indicator will alarm automatically.

10. Plate Mounter

• It has a screen including the bilateral symmetrical split screen display
• It is used for the plate mounting to realize the purpose of multi-color overprinting
• One set image segmentation device
• 2 high definition cameras for magnifying
• Quickly changes the print plates

11.Web cleaner

• To guarantee the cleanness of substrates
• clean the dust in vacuum and then remove dust

12.Corona Treater (Optional)

• To increase ink adhesion to film side of printing materials
