INTRODUCTION OF THE JC MASTER PERFECTING RANGE

Full servo drive with vacuum transfer with both top and bottom printing in one pass (perfecting).

From servo driven lead edge feeder, through automatic board cleaning and dust control, exceptional print quality on each side of the sheet with integral drying. After this duplex printing, the option to add a twin slotting unit and dual diecut unit is also available.

 

FEEDING UNIT

  • Lead edge feeder with synchronized servo motor and electronic cam control, zero gap linkage between front feeding rollers and shafts ensures the long term accuracy of the feeder.
  • Independant drive allows maximum control of the feed.
  • Direct drives ensures minimum dependence on feed rolls and, as such, retains the intergrity of the corrugated sheet by reducing crushing.
  • The feeding rubber roller and position adjustment of feeding front guage are controlled by servo driving system; data correction is made on the HMI screen or by push button; back stop is also fully motorized.
  • The high voltage electrostatic, contact dust and negative pressure dust section mechanism removes cardboard impurities and dust to improve the quality of sheet for printing.
  • Equipped with independant dust collection unit.

PRINTING UNIT

  • The virtual axis multi servo sychronization independantly controls the print cylinder, ink roller and anilox roller.
  • With fast order-changing mechanism, phase correction function and intelligent registration for exceptional print tolerances.
  • High quality alloy steel roll shafts are ground and hard chrome plated, and dynamically balanced to enable stable and reliable operation.
  • Full vacuum transfer with ceramic coated rollers on steel shafts.
  • Automatic lifting of anilox to transfer ink to ensure printing quality and prevent damage.
  • Each print unit is equipped with 5.7 inch colour touch screen, using servo drive to adjust the gaps between rubber rolls, anilox rollers and printing rollers. The adjusting the precision is 0.02mm.
  • The ARO double diaphragm ink pump with automatic reversing device ensures consistent supply of ink for high quality of printing.
  • Each unit is independently driven which eradicates the problem of accumulated printing error position. The automatic intelligent zero set system of the print roller can improve the print repeatability accuracy.
  • The ceramic anilox roller is equipped with the closed cavity double blades to enable the printing of 100-150 dpi.
  • Equipped low ink alarm device, to prevent defective printing products and reduce the consumption of printing ink to save water and time.
  • Self cleaning function to achieve fast cleaning of residual ink.

DRYING UNIT

  • Vacuum transfer with independant servo drive. 
  • The machine is equipped with automatic thermostatic control.
  • Infrared lamps.
  • Single-tube duplex heat transfer to accelerate drying speed and improve operation efficiency.
  • Motorised adjustment for transition table.
  • Optional UV curing mechanism for varnish.

SLOTTING UNIT

  • With touch screen and button operation adjustment system; full safety emergency stop buttons.
  • Using PLC to directly control the servo motor.
  • Servo driven pre-crease and creaser are synchronised and servo driven gap adjustment.
  • The slot shaft is servo driven with full compensation correction on the run; the distance between rollers can be adjusted.
  • The radial operation of slot heads are independantly driven by servo, which controls the position of leading and trailing knife.

DIECUTTING UNIT

  • With HMI touch screen and full safety emergency system.
  • The transmission of the transfer rollers is seperately driven to correct the position of sheet at any time; the gap between two rollers is adjusted by the servo.
  • The die cylinder and anvil are driven seperately so as to achieve compensation of line speed between the rollers; the pressure between rollers is controlled by servo also.
  • Servo controls the axial operation of die cylinder and anvil for improved accuracy.
  • Set up with anvil sychronization mechanism to provide consistent line speed.
