I. Characteristics of Structure and Performance:The complete machine adopts high trademark damping cast iron wallboard with trouble free damping and stability in order to ensure high-speed operation of equipment.All the guide rollers adopt aluminum alloy, surface oxidation, dynamic balance handling, small inertia so as to keep little tensile waviness.Tension adopts Japan Mitsubishi closed loop tension control system, reliable performance and conform stable tension.Winding & unwinding adopt air inflatable shaft and convenience for work.Printing adopts non-mandrel air-actuated clamp plate, pneumatic pressurizing, handiness and direct-viewing pressure.Adjustable three-dimension scraper position, twin cylinders pneumatic pressurizing with scraper shifter.Printing register adopts computer register system??fast registration and high precision.10-zone heating drier, automatic control temperature, digital display, closed cycle hot air form. The upper zone adopts pneumatic cover-opening type, high voltage forcing waste discharging and with chain traction paper passing through mechanism.To guarantee winding neatly, the pendulum roller photoelectricity deviation rectifying system is set at the drier outlet.Before winding, two cooling mechanisms of air-cooling and water-cooling are equipped with.Transmission adopts imported frequency converter, high precision, built in gearbox to ensure normal operation of machine and speed regulating system.The winding adopts moment electrical motor, constant tension & constant linear speed winding.
