Functions and features
1The whole machine computerized PLC control, convenient and reliable.
2All driving rollers are high grade steel, plate with the hard chromium, abrade outside.
3Drive gear adopt 20CrMoTi high grade alloy steel to grind the day after tomorrow but becomes and goes through 60 degree of heat treatment Rockwell hardness greater than.
4 Each unit electrically departing, pneumatic locking, pneumatic general locking, sustained bell warning during moving, ensures operation personnel safe.
5 Different start and stop warning rings.
6 Start the machine by both hands, ensures that handling person safe.
7In front, middle and the end, there are emergency stop buttons.
8There are different guiding lights for switching-on, standby, moving and abnormal (three-color guiding lights of LED).
9 There are emergency stop buttons in each unit which can stop the moving of the unit inside to ensure the operators safe.

10Adopting ceramic anilox rollers and double doctor blade chamber system
11 Adopting int'l famous brands electric fittings for the whole machine. The complete machine zeroes without exception , wipe printing plate memory and preset function, printing and die-cutting phases zero, pre-adjustment and accurate adjustment, phase adjustment, all above make the whole machine with much higher accurate.

Characteristics of each unit

A. Feeding section

  1) Main control panel consists of touch screen, VFD controller and buttons, convenient and reliable.

  2) Main motor switching-on is controlled by double buttons which ensure the safety of the operators and the main machine.

  3) Continuous and skip feeding (with counter) (choosing skip feeding if necessary).

  4) Paperboard feeding counting setting, displaying production quantity.

  5) Left and right baffles are controlled by motor-driven with gauge display.

  6) The gap of the front baffle is adjusted manually. And there are dust-removing brushes at the rear of the baffle to clean the dust and miscellany and improve the printing quality.

  7) Four shafts front edge feeding motor 11.0Kw, auxiliary suction feeding, can adjust the suction strength as per the warping degree of the paperboards to ensure smooth feeding.

  8) Upper feeding roller outer dia. 149 mm, coated with anti-wear rubber which can avoid to press down the paperboard.

  9) Lower feeding roller outer dia. 149mm, chrome coat with anilox.

  10) Cross slide block coupling transmission to decrease abrasion and make transmission much more stable.

  11) Electromotive control clutch, and with continuous alarming while moving to ensure the operators safe.

  12) Driving shaft with electromagnetic abrasion clutch to avoid faulty operation or protect motors while overload.

  13) Automatic return to zero in Feeding, printing and die cutting sections.

  14) Air pressure interlocking devices.

B. Printing units

  1. Forme roller

    1) Forme roller outer dia. 390.6mm (405mm including the forme)

    2) Printing roller with fine grinding and chrome coated.

    3) Balancing correction, stable running.

    4) Forme-hanging device, single side locking, accurate, convenient and fast.

    5) Forme-hanging groove at the whole forme, suitable for 10mm forme-hanging slices.

    6) Foot switch electromotive control the rotation making it easy to mount and disassemble the forme.

2. Print-pressing roller

  1) Outer dia. of the print-pressing roller 130mm.

  2) Fine grinding with chrome coated.

  3) Balancing correction, stable running.

  4) Self-locking device for the gap adjustment, adjusting range 0-11mm.

  5)

3. Ceramic anilox rollers(180LPI – 700LPI optional).

  1) Anilox roller dia. 187.57mm.

  2) ceramic material.

  3) Even ink applying, lengthen the life of the forme and the rubber roller.

  4) Air pressure automatic lifting gear match the feeding section (the anilox roller descends to contact with the forme while printing, and the anilox roller lifts to depart from the forme while stopping printing).

  5) Double doctor blade chamber system

    Doctor blades form a sealed chamber with the ink inside,promote the printing quality with excellent inking quality (much better than the rubber roller inking system). It can save much ink during the printing process. Automatic clear system for the anilox rollers and doctor blade.

    China famous brand.

C. Die cutting section

   Accuracy of die cutting: ±1.0mm

1. 1.      Operation

1)      The die roller and the anvil roller will separate automatically via cylinder eccentric device while not die cutting, which can decrease the idle load and lengthen life of the anvil and the die.

2)      Plant-type gear structure, the same as that in printing section.

3)       PLC control and 360 degree electric and digital adjustment for the die cutting phases.

4)      Electric digital transverse movement, range: 10mm.

5)      with the anvil correction device which can make the anvil roller to be used repeatedly.

2.      die roller (lower roller)

1)      Outer dia. 360mm, not including the die.

2)      Cast with fine grinding and hard chrome plated

3)      Balancing correction, stable running.

4)      The hole distance of the fixing screw for the die, axial direction: 100mm, radial: 20 aliquot.

5)      Knife height: 25.4mm.

Wooden die plate thickness: 16-18mm (for 3ply corrugation paperboard)

                       17-15.3mm (for 5ply corrugation paperboard)

  3. Anvil roller (upper roller)

     1) Outer dia. 384mm.

     2) Alloy steel with fine grinding and hard chrome plated.

     3) Balancing correction, stable running.

     4) Manual adjustment the gat with the die.

     5) Anvil thickness 10mm, width 250mm, normal life: 8 millions times cutting.

     6) Mechanical transverse movement 50mm.
