Wholesale Four Colour Flexo Printing Machine - High Speed Central Drum 6 Colour CI Flexo Printing Machine For paper products – Changhong

Characteristic

• The machine introduction & absorption of European technology / process manufacturing, supporting / full functional.
• After mounting the plate and registration, no longer need registration, improve yield.
• Replacing 1 set of Plate Roller (unloaded old roller, installed six new roller after tightening), only 20 Minute registration can be done by printing.
• The machine first mount plate, pre-trapping function, to be completed in advance prepress trapping in the shortest possible time.
• Maximum production machine speed up 200m/min, registration accuracy ±0.10mm.
• The overlay accuracy does not change during lifting running speed up or down.
• When machine stop, Tension can be maintained, the substrate is not deviation shift.
• The whole production line from the reel to put the finished product to achieve non-stop continuous production, maximize product yield.
• With precision structural, easy operation, easy maintenance, high degree of automation and so on, only one person can operate.

technical specifications

Drying System

It adopts electric heating, which is converted into circulating air heating through a heat exchanger. The temperature control adopts an intelligent temperature controller, a non-contact solid state relay, and a two-way control to adapt to different processes and environmental production, save energy consumption, and realize PID temperature control. Temperature control accuracy ±2℃

Electric control system

• One set of main control panel: the electric control cabinet is designed and manufactured according to IP21 safety protection level; According to setting/modification, operating parameter monitoring/recording, including online help, alarm prompt, historical data record
• The tension control system of the whole machine is controlled by the ultra-light floating roller closed-loop, and is controlled by the PLC to control the human-machine interface and the touch screen to display/set it.
• The whole machine is in jog operation, group control linkage; the main screen can simulate the working process status of the machine. Each power point has work instructions (green constant light), stop instructions (red light flashes), fault indication (red light flashes), single roll length, cumulative length, line speed, and PV value (tension value) at each tension detection point
• The temperature control part has an independent temperature control meter. There are SP and PV value display. Can monitor the working status of all fans in the oven, It has the functions of warning (non-stop) and alarm (stop), and the alarm is released after the fault is eliminated
