Advantages

  • Human machine interface touch screen (HMI) & CNC printing station positioning system
    1. CNC program system control to give orders in wide span TFT colorful HMI touch screen. Simple & easy.
    2. The other country languages by English letters can be put into HMI touch screen.
    3. Exclusive 2nd pass control program system. Computer will micro-adjust the scanning range tolerance automatically to get best 2nd pass registration. Many control items can be set in HMI "2nd pass setting page".
    4. Full-automatic inspect machine status such as electric current overload, servo breakdown...etc and alarm in the HMI "Error Inspection Page". So the maintenance is very easy & secure.
    5. Web tension can be set (micro adjustment) in HMI touch screen for different specifications web materials needs. The setting tension ratio can be changed automatically while speed variation.
  • Printing station construction & Electrical parts

    * SPM-280LR printing station digital control panel

    1. Get rid of traditional printing station positioning operate by manual, CNC printing station positioning computer digital controlled can do micro-adjust to achieve 0.01 mm (10 micron, u) accuracy just give order to computer (10 u tolerance is impossible to be made by manual) .
      *SPM-340LR by central control in HMI touch screen, SPM-280LR by digital panel control of each printing station
    2. Computer will auto-adjust the printing registration due to speed variation or restart the machine printing. Operator no need to re-adjust many items again & again manually as other machines. Less trouble and save lots of material wastage.
    3. Thanks to Independent servo drive inking speed system in each printing stations, ink volume adjustment by CNC computer digital control to do precise micro-adjustment while printing. Computer will change ink leaking volume automatically according to the printing speed variation. Easy, efficient, no wastage.
    4. Oscillating swing ink rollers in each printing station can make ink more average spreading to get best printing quality. Vacuum electroplate alloy rollers no rust, less consumption. Printing overlap shadow erasing rollers operator can compose to fit different printing jobs demand.
    5. Simplified printing pressure micro-adjustable switches can adjust the opposite edges of printing pressure in the same time, operator no need to adjust both sides pressure many times also to put his hands inside the printing station, less trouble & save time (if required one side manual adjustment is available also) . Impression rollers easy changed for maintenance.
    6. UV flexo Varnish Coating station (V)design for quick changeable Anilox roller benefit for Varnishing or Flexo ink coating thickness variable application. Choose Full-rotary mode the coating will be more efficient.
    7. When printing station not using, operator can stop the station operating no rollers consumption.
    8. Size variation just input the order size in HMI touch screen, no need to change cylinders & gears, save time & cost. Printing cylinders can choose Take out or Askew adjust or Magnetic 3 styles to have its advantage :
      Take out style : to prepare next jobs printing plates mounting on the spare cylinders is convenient;
    9. Central management electronic control instead of by many wires connection benefit for signal transmit speed, maintenance and longer life.
      Durable Electrical parts such as Current Filter to skip wrong electrical messages; Current Breaker auto-stop current once power problem arise to protect machine etc.
  • Machine body & UV control system

    * Specialize feeding drum

    1. Machine body made by professional CNC hole drilling and One body integrated molding. Machine parts made by CNC lathe to achieve strict QC request.
    2. Professional Specialize liner sliding tracks make printing registration precisely. Oil sealed complicate bearings on many parts of machine no wear & tear, easy for maintenance, durable.
    3. Specialize feeding drums no pressing traces remain on web while feeding. (as above photo).
    4. Up to 3 sections UV strength can be choose.
    5. When printing station not using can stop the UV station operating no UV glasses consumption.
    6. Cool UV glasses can handle some special materials such as PVC,PE,PET etc to against shrinkage is available for standard unit.
    7. Smaller machine body but has more applications & functions, easy for moving and save the space of factory.
  • Tension control, On-line working & Ink washing

    * Machines on-line reciprocal system & loop box unit (RS)

    1. Machines on-line reciprocal system & loop box unit (RS) for Die-cut, Hot-stamping machines on-line with Rotary printing machine by unique computer systems & devices to prevent speed uncoordinated caused bad registration, web jammed even web twist broken situation. Dancing roller in loop box is benefit for web smooth feeding. ( The unit as above photo ).
    2. Automatic computer controlled Ink washing unit can wash printing station easily & convenient in very short time.
    3. Printing station lubricate piping unit benefit for maintenance & longer life.
    4. Extra large printing area 430 x 270 mm, super high speed 200 RPM (12,000 imp/hr). Speed variation gradually for machine protection.

      On-line with SPM-320F : CNC High speed Single station Die-cut (Hot-stamping) machine (Flat-bed Die)or SPM-320FT : CNC High speed Twin station Hot-stamping & Die-cut machine (Flat-bed Die) can achieve 200 rpm (imp/min); 12,000 imp/hr super high speed.
      Check SPM-320FT
    5. Check SPM-320F ** this term for SPM-280LR only
