Vacuum Coating Machine

الوصف

Purpose: ZZL***0/**0 high vacuum web coater is specially designed metallizer for coating zinc and aluminum by means of thermal evaporation on the surface of rolling material for capacitors. It is also extensively used for the production of metallic packing materials for food industry, decorative or packing material, electrochemical aluminum material, various labels, sticks and trade marks as well as all kind of reflective material, heat preservation or heat insulation materials and electric material. Features and advantages: With a set of reliable fast-sucking pump group equipped, winding and unwinding system controlled automatically by PLC, it can realize high vacuum condition and automatic operation with easy manipulation. The driving system of main guide roll adopts DC control system equipped with high resolution encoder, can insure high stability of rolling speed in the course of winding and unwinding and eliminate the influence of voltage fluctuation and of load changes. The winding and unwinding system with direct torsion control by DC motors to realize substrate rolling operation, adapts itself to the thin, narrow and highly stretched substrate films. At the lateral of rewinding roll set up with auxiliary tension guide roll driven by independent motor, insures the precision of tension control. The winding and unwinding system also equipped with electrical-arc leveling roll to realize directly corner control from outside chamber. The leveling roll can realize on-line adjustment and modification as per actual needs during the course of operation.
