    Main Configuration
    • Feeding Unit
      Feeding Unit
      Feeding Unit
      Adopts a sun-wheel feeder with vacuum-assisted board feeding to ensure smooth and orderly feeding; the air volume can be adjusted according to the curvature of the corrugated board.
      A main motor safety interlock prevents the motor from starting unless all machine sections are securely locked.
      Both continuous feeding and skip feeding are available, in addition to an integrated counting device.
      The dual rubber feed rollers feature grooved surfaces to prevent excessive pressure on the corrugated board.
      The rubber feed roller incorporates a pneumatic cushioning device for accurate feeding; this design maintains stable feeding when the roller gap is small and board hardness varies.
      The side guides are adjusted electrically and include a digital position display; an automatic pneumatic alignment device is available as an option.
      The rear guide is electrically adjusted, while the front guide gap is adjusted manually and synchronously.
      A brush-type dust-removal system with a suction blower removes paper dust before printing; air volume can be adjusted according to the board size.
      Each feeding unit can be moved electrically to the left or right; an audible warning sounds during movement to ensure safe operation.
      The electronic counter allows preset production quantities. An alarm is triggered automatically when the target is reached. With the optional touchscreen system, production data can be displayed on screen.
    • Printing Unit
      Printing Unit
      The gapless printing cylinder is precision ground, dynamically balanced, and hard-chrome-plated to ensure smooth and stable operation.
      A quick-change printing plate system makes plate installation and removal easy. A foot switch controls forward and reverse rotation of the printing cylinder.
      The gap adjustment for the feed roller, impression roller, rubber roller, and anilox roller uses self-locking mechanisms to keep settings stable.
      The printing cylinder phase is electrically adjusted via the PLC over a full 360°. Correction values can be entered directly, and adjustments can be made while the machine is running or stopped.
      Axial movement of the printing cylinder is electrically controlled via the PLC. Correction values can be set according to printing deviation, with an adjustment range of ±10 mm.
      A pneumatic braking device locks the phase position when a printing unit is opened or cleaned, preventing movement and keeping the original gear position unchanged.
      Pneumatic lifting of the anilox roller is synchronized with the board feeding system. The anilox rollers lower one by one when feeding starts and automatically lift when feeding stops.
      A pneumatic diaphragm pump ensures automatic ink circulation and supports water-assisted cleaning.
      The printing plate cleaning memory function automatically returns the printing cylinder to its original printing position after cleaning.
    • Slotting & Creasing Unit
      Slotting & Creasing Unit
      Pre-creasing wheels help prevent the corrugated board from cracking during creasing.
      The single-shaft, double-knife slotting structure allows the carton height to be adjusted electrically by entering data through the PLC, with touchscreen adjustment available as an option.
      Slotting phase can be adjusted electrically through the PLC over a full 360°, and correction data can be entered while the machine is running or stopped. A touchscreen control option is available.
      The slotting knives and creasing wheels are moved horizontally through synchronized electric adjustment.
      Gap adjustment for the creasing rollers and slotting knife rollers adopts self-locking mechanisms.
      The carton-height adjustment system includes an anti-collision device that protects the slotting knives and machine components.
      Equipped with an additional anti-collision device that protects the slotting knife holders during electrically controlled horizontal movement.
      The sawtooth slotting knives are made of alloy steel and are heat-treated and precision-ground for wear resistance, sharp cutting edges, and accurate slotting; the two-piece cutting knife design further improves cutting precision.
      Dies for ventilation holes and hand holes are available as optional equipment.
    • Die Cutting Unit
      Die Cutting Unit
      The rubber cushion roller is mechanically driven to oscillate laterally over a 40 mm range, helping to distribute wear evenly across the cushion surface.
      Die-cutting phase can be electrically adjusted via the PLC over a full 360° and correction data can be input while the machine is running or stopped. A touchscreen control system is available as an option.
      Axial movement of the die-cutting cylinder is electrically controlled via the PLC; correction data can be entered based on die-cutting deviation, with an adjustment range of 10 mm. Touchscreen control is available as an option.
      The gap between the rubber cushion roller and the die-cutting cylinder is adjusted using a self-locking mechanism. A pneumatic quick-adjustment device enables fast, wide-range setting changes, reducing cushion wear and extending service life.
      Feed roller gap adjustment also adopts a self-locking structure.
      A speed compensation system synchronizes the rubber cushion roller with the die-cutting cylinder. By regulating the surface speed of the cushion in line with the die cylinder, the system helps ensure the finished carton profile accurately matches the die design.
      A rubber cushion repair device is supplied with the machine, allowing the cushion to be refurbished and reused.
    • Automatic Stacking Unit
