Feeding Unit

• The leading-edge feeding system adopts a light-pressure feeding mechanism, reducing friction between the board and feeding table by approximately 60%. This protects the original strength of the corrugated board while preventing flute collapse and over-compression, and ensures smooth feeding after creasing. The system operates stably, with accurate and fast sheet feeding, and is suitable for all types of corrugated board.
• Vacuum-assisted feeding is applied, with adjustable air volume and air pressure according to board size.
• Features a double transport roller structure, with one set of feeding rollers that adopts pneumatic elastic rubber rollers, preventing damage to the corrugated board strength. Combined with an upper suction dust removal device, which effectively removes impurities from the printing surface and improves printing quality.
• The left side gauge and rear backstop positions are electrically adjustable and equipped with a pneumatic sheet alignment device for more accurate lateral positioning.
• A 10.4-inch color touch screen controls the feeding unit, printing unit, slotting unit, and die-cutting unit for one-touch reset function for storage, memory, fixed-speed operation at 60/80/100, infrared photoelectric counting, and preset order quantity control.

Printing Unit

• Printing rollers and transmission shafts are manufactured from high-quality steel, precision-ground and hard chrome-plated, with computer-controlled dynamic balancing to eliminate centrifugal force.
• The printing roller adopts a plate-mounting device with a ratchet-type fixed plate shaft and a full-slot hanging plate structure. The foot-operated electric control enables forward and reverse rotation for fast and convenient plate installation and removal.
• The rubber roller ink distribution system uses a steel core wrapped with wear-resistant rubber and precision-ground for effective ink transfer. (Optional: doctor blade ink system.)
• Anilox roller is ground and embossed on the steel surface, hard chrome-plated. (Optional: ceramic anilox roller, line count selectable from 160–500.)
• Printing phase and axial adjustment adopt a planetary gear structure, controlled by a PLC touch screen with 360° digital adjustment, which can be adjusted during operation or stoppage. The inverter motor drive allows accurate circumferential speed adjustment of the printing roller within 0.1mm.

Die-Cutter Unit

• Rubber pad roller: Manufactured from centrifugally cast steel and is dynamically balanced, precision ground, and hard chrome plated. It is equipped with a mechanical transverse oscillation device (±20mm) to extend the service life of the rubber pad. An automatic differential speed compensation system is incorporated to correct die-cutting deviation caused by rubber pad wear.
• Die-cutting roller: Also manufactured from centrifugally cast steel and undergoes dynamic balancing, precision grinding, and hard chrome plating to ensure durability and cutting accuracy.

Slotter Unit

• All carton dimensions, including carton height and phase, are completed by computer through a human-machine interface, improving efficiency and enabling storage of up to 500 regular orders.
• The double-shaft structure with large-diameter creasing wheels ensures excellent carton forming performance.
• The slotting knife holder, creasing wheel, and trimming knife adopt a precision ball screw lateral movement structure, providing high positioning accuracy and extending tool service life.
• The elastic corner cutting knife structure allows cutting of 3 ply and 5 ply corrugated board without adjustment.
• Slotting knives are made of high-quality alloy steel, heat-treated and precision-ground, offering excellent hardness and toughness for long service life.
• Hole punching and hand-hole punching devices are available as options according to requirements.
