Characteristics of each unit

A. Feeding section (lead edge feeding)

  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. φ149 mm, coated with anti-wear rubber which can avoid to press down the paperboard.

  9) Lower feeding roller outer dia. Φ149mm, 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. Vacuum dust cleaning unit

   Cleaning the dust on the surface of the paperboard to improve the printing quality.

C. Printing units

    1. Forme roller

        1) Forme roller outer dia. Ф405

        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 ф130mm.

        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. Steel anilox rollers (anilox roller 200LPI, 220LPI and 260LPI)

        1) Anilox roller dia. Ф187.57mm.

        2) Steel 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) Rubber roller ink even-distributing roller.

    4. Phases adjusting structure

        1) Plant-type gear structure.

        2) Digital display for the phases, making the operation much more convenient, intuition and correction.

        3) PLC control and 360 degree electric digital adjustment for print phases.

        4) VFD control for adjustment for the forme roller, it will be faster to return to zero or change the forme, and make it faster to change the forme.

        5) The whole machine and the feeding part will automatically return to zero, accuracy 0.5mm, then the phases will adjust automatically and roughly, and then input parameters after test running one sheet, which can greatly avoid waste.

    6. Ink circulation system

        1) Air-pressure type diaphragm pump, stable ink supply and easy operation.

        2) The pump can not supply ink before the rubber roll and the anilox roller gather up.

        3) Ink filtering device.

    7. Print phases fixing device

      Pneumatic brake structure. When units separate, the brake device limits the gear moving, which can keep the phases unchangeable.

    8. Axial adjusting structure

        1) Axial electric adjustment for print roller, range: ±10 mm.

        2) Digital display for position, making it convenient, intuition and correction to operate.

D. Slotting section

  1. Pre-pressing wheels. The paperboards will be not easy to be broken after Pre-pressing.

  2. Manual adjustment for pre-pressing wheel gaps.

  3. Manual adjustment for groove wheel gaps, the data will be displayed on the dial scale.

  4. The width of the slotting knifes is 7.0mm. Alloy steel, two-piece type edge trimming knife, sharp and high precision.

  5. Manual adjustment for the slotting knife base gap, the data will be displayed on the dial scale.

  6. Plant-type gear structure for the slotting phases adjustment.

  7. PLC control and 360 degree electric and digital adjustment for the slotting phases.

  8. Axial synchronous electric adjustment for the slotting upper and lower knife bases, pre-pressing upper and lower wheels and precise pressing upper and lower groove wheels.

  9. the structure of the upper and lower slotting knives discs is forward and backward double discs, that is to say, the forward knife and the backward knife are mounted on different bases, which makes it easy to operate, adjust and maintain.

D. Inline folder gluer

  1. Technical date

2. Features

1) Inline with the flexo printer slotter machine

2) Gluing Part: Glue tank flexibly contacts with the gluing wheel without glue leakage.

3) Folding unit

  a) Convenient to adjust folding guide bar, shorten the time for sheet changing.

  b) Good rigidity of bottom folding arm ensures fine performance on hard paperboard.

  c) Squaring function improves the precision of carton boxes.

4) Flapping & Ejecting unit

  a) Longer time for first flapping is favorable for enhancing adhesion precision.

  b) Re-flapping structure can eliminate scissor gap and fish tails.

  c) Stable ejection structure decrease failure rate.

5) The whole machine

  a) PLC program control, adjust parameter automatically by input paperboard sizes.

  b) Speed can be adjusted by the printing machine control panel connected by the comm. Cable. And failure and emergency stop are correlative.

  c) Smooth paperboard transportation at the joint point with the printer slotter.

  d) Down folding method makes it easy to adjust and change paperboard.

  e) Imported belt with high quality, stable and durable.
