Controle de servos para máquina de impressão flexível multicoloridas FM-C (Enrolamento e desenrolamento sem parada da máquina - Opcional)

Function Units

1.Unwinding Unit ( nonstop unwinder & rewinder device as optional )

• Shaftless unwinding unit
• Unwind unit 60”(1524mm)capacity
• Mandrel 3” and 6” diameter
• Hydraulic paper shaft lifting and descending device: mainly used for loading and unloading of paper rollers, no need of forklift or other handling tools
• Web break sensor, automatically shut down when paper broken

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
• Infeed unit with servo motor drive, epicyclic gear box

• Servo motor conrtol press cylinder,can realized the pre register function, the anilox roll and printing cylinder are gear box drive
• Plate cylinders is desinged in petal type structure and the plates can be changed without tools and no need adjust the pressure.
• 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
• Automatic horizontal and vertical registration.
• Reversed single doctor blade
• 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

Auto Register:

• The first color printing unit is the benchmark and the following printing unit registers automatically according to the first color.
• The automatic registration controller can adjust the phrase position of the servo motor according to the detected error, realizing the quick registration, improving the operating quality and the extent of automation, so the machine greatly reduces the labor intensity and attrition rate of raw materials

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 piece

7.one stroboscope lamp

• It can be enlarged 18 times of image
• Out Feed Tension Control System
• The rear tension unit is made of alloy and cast iron
• Use the double side pressure rubber to cluth and feed and to guarantee the stale tension
• unit with servo motor drive,  epicyclic gear box

8.Rewinding Unit ( nonstop unwinder & rewinder device as optional )

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

9. Automatic Lubrication 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 printing plates

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

• To increase ink adhesion to film side
