Main Configuration

Feeding Unit

Utilizes no-crush wheels and vacuum assistance to feed the cardboard smoothly, enhancing the appearance of the feed. The airflow can be adjusted according to the curvature of the cardboard
Equipped with mechanisms for continuous or intermittent feeding and counting of cardboard sheets
Features dual rubber rollers with grooves to prevent excessive pressure and ensure smooth feeding
Equipped with a cylinder buffer system for precise feeding, especially useful when dealing with smaller feed gaps where cardboard hardness cannot be detected
Includes a dust removal brush with an attached suction fan, adjustable based on the size of the cardboard
Allows setting of production quantities, with an automatic alarm once the set quantity is reached
Printing Unit

Uses gapless rollers that are surface-polished, balanced, and chrome-plated for smooth and stable operation
Equipped with a quick-change plate system, controlled by a foot pedal switch for easy forward and reverse roller movement
Self-locking structures for adjusting gaps between the feed roller, pressure roller, glue roller, and anilox roller
Utilizes a pneumatic diaphragm pump for automatic ink circulation and water-based cleaning
Includes a cleaning memory function that returns the printing roller to its original position after cleaning
Slotting & Creasing Unit

Includes pre-press wheels to prevent the cardboard from cracking during the creasing process, ensuring a smooth finish
Featuring a single roller with dual blades for efficient slotting, the carton height can be adjusted using a PLC system with electric input, with an optional touchscreen for easier control
The slotting blades and creasing wheels are adjusted horizontally using an electric synchronization system, ensuring precise alignment and consistent results
A collision prevention mechanism is included for height adjustment, protecting the flexo printer slotter from damage
Made from alloy steel, the sawtooth-shaped slotting blades are heat-treated and ground for superior durability, sharpness, and precision
Die Cutting Unit

The die cutting unit uses a PLC and electric 360° adjustment for the die-cutting phase. The system allows input of adjustment data based on errors and can be adjusted while the corrugated cardboard machine is running or stopped. An optional PLC with a touchscreen is available for easier control
The gap adjustment between the rubber roller and die roller features a self-locking structure. It uses a cylinder for quick, wide-range adjustments, reducing rubber wear and extending the life of the rubber
Automatic Stacking Unit

Features a chain drive for lifting and lowering the stacking platform
The platform adjusts its angle according to the cardboard stack, and the lift motor includes an electric braking function to ensure precise positioning
The unit can handle cardboard stacks up to a height of 1600mm
