Unit Type 4/5/6/7/8 Color Flexography CE Approved Flexible Packaging Printing Machine
Introduction This machine is a printing machine which adopts flexible photosensitive resin plates, rubber plates as the base material, anilox rollers for transferring ink, liquid ink for printing. It is controlled centrally by PLC system and generally consists of unwinding section, infeed section, printing section, drying section, outfeed section, rewinding section and control section. This machine is an ideal machine for printing paper cup, carton, paper bag, paper package, and so on.
Features
Separate single-station unwinding rollstand with hydraulic lifting device; 3convex-type inflatable shaft for loading material (or shaftless loading); Automatically constant tension controller for unwinding tension control and EPC web guide control system for material alignment; Alarm function for reminding replacing material, stopping-machine device for detecting material broken and dust collection device.
The machine is mainly controlled by inverter-fed motor with synchronization belt.
Double rubber nipper roller is used for paper feeding, whose pressure can be adjusted by pneumatic cylinder; Taper tension control system ensures the color registration accuracy.
Ceramic anilox roller for ink transferring; Single-blade reverse ink-scraping system; Pneumatic clutch pressure for anilox rollers and plate rollers; Color Registration: Y axis (automatic), X axis (manually).
Automatic Preventing Clogging Function: When the machine stops, the anilox roller will rotate to prevent the ink on its surface from drying and blocking holes (meshes) on it.
Double rubber nipper roller is used for paper feeding, whose pressure can be adjusted by pneumatic cylinder; Static picture color detection system (Kesai) is adopted in this section.
Separate single-station rewinding rollstand with hydraulic lifting device; 3convex-type inflatable shaft for loading material (or shaftless loading); Stopping-machine device for detecting material broken.
Separate drying system (electric heating); I. R. Short-wave heating and drying system (the temperature is adjustable); Hot air and natural air drying system including exhaust fan and blower; Hot air recycling system, with adjustable device for in/outfeeding air; Central Exhaust System: Waste gas will be exhausted centrally by exhaust fan.
The whole machine is centrally controlled by PLC system, which has self-diagnosis function and monitors the machine status; The runnning speed can be adjusted at multiple points.
