The Full Vacuum Transfer Flexo Printer Slotter Die Cutter is a high-specification corrugated box converting machine featuring a high level of automation. It delivers accurate and stable printing and converting performance even at high production speeds. The carton printing machine integrates feeding, flexographic printing, creasing, slotting, die cutting, waste stripping, and automatic sheet stacking into one complete production line, allowing corrugated sheets to be printed, creased, slotted, corner-cut, and die-cut in a single pass.

The carton printing machine adopts full vacuum transfer technology combined with a high-precision servo leading-edge feeding system, ensuring stable, accurate, and efficient sheet feeding. It is suitable for processing 3-ply, 5-ply, and 7-ply corrugated sheets.

The machine features a high-efficiency, energy-saving variable-frequency drive system, allowing the airflow to be adjusted according to different corrugated board materials. This ensures stable sheet feeding while reducing damage to the corrugated flutes. The all-ceramic vacuum suction feed wheels, together with the high-precision servo leading-edge feeding system, effectively accommodate different levels of sheet warp, improving feeding accuracy and stability during continuous production.

The printing section adopts an advanced ink distribution and transmission system, combined with high-precision gear transmission and imported drive motors. This design reduces operating noise, improves transmission stability, and enhances printing and registration accuracy. The system provides uniform inking and adjustable ink volume, and is equipped with a low-ink alarm system to help prevent printing defects and rubber roller damage caused by insufficient ink.

The die-cutting unit adopts independent servo drive technology, allowing the die-cutting unit to operate independently from the main drive system. This effectively reduces mechanical wear while increasing machine speed and improving both printing and die-cutting accuracy. Parameters such as pre-creasing, final creasing, and slotting knife rings can be quickly adjusted through the computerized control system, reducing job changeover time and improving production efficiency.

The machine is equipped with an intelligent sheet-passing gap adjustment system, which allows the gaps between machine units to be quickly adjusted according to the thickness of the corrugated board. The system also supports incremental fine adjustment for precise setup. Combined with the central control system, operators can centrally adjust parameters such as machine phase, lateral movement, unit gap, unit engagement/disengagement, and operating speed, making machine setup and operation simpler, faster, and more efficient.

Performance Features：

• The machine integrates feeding, flexographic printing, die cutting, and stacking functions, and can complete printing and die cutting of 3-ply and 5-ply corrugated sheets in a single pass.
• Full vacuum transfer system: The machine adopts a high-efficiency, energy-saving 7.5 kW variable-frequency motor and all-ceramic vacuum suction feed wheels, providing accurate, smooth, and fast sheet feeding.
• Advanced ink distribution and transmission system: The machine features an optimized ink distribution and drive system with imported motors, cross-joint shafts, and gear transmission. This design reduces operating noise, improves transmission stability and rigidity, increases running speed and machine stability, and enhances printing and registration accuracy.
• Uniform and controllable inking: The inking system provides uniform ink distribution and precise ink-volume control to prevent ink overflow and keep the external ink circuit clean. A low-ink alarm system is also provided to prevent damage to the rubber rollers caused by insufficient ink and effectively reduce waste production.
• Oil-level balancing system: Each machine unit is equipped with a contact-type circulating oil-level balancing system to prevent insufficient lubrication or oil overflow in individual units.
• The machine is equipped with a multi-tone warning speaker from Korea. Different sounds are generated for phase adjustment, lateral movement, gap adjustment, zero positioning, unit engagement/disengagement, and safety warnings, helping operators confirm that each operation has been completed before safely starting the machine.
• Intelligent machine gap adjustment: The gap between the machine units can be adjusted intelligently. Simply place the corrugated sheet to be processed at the board testing position and press the confirmation button. No frequent manual adjustment is required, making operation simple and efficient. The system also features incremental fine adjustment, with independent micro-adjustment of the gap available at each unit and the central control console. (Patented technology)
• Servo leading-edge feeding system: The servo leading-edge feeder provides high-precision sheet feeding with intelligently controlled feeding timing. It can handle rigid kraft linerboard as well as 3-ply, 5-ply, and 7-ply corrugated sheets. The vacuum-assisted feeding system effectively compensates for variations in sheet warp, ensuring smooth and stable feeding.
• Doctor blade chamber: A doctor blade chamber is available, with a ceramic anilox roller assembly available as an optional configuration.
• Independent servo-driven die-cutting unit: The independent servo drive significantly improves both printing and die-cutting accuracy. Pre-creasing, final creasing, and slotting knife-ring adjustments can be controlled and adjusted with one click through the computer control system, improving efficiency and reducing job changeover time.
• The machine is also equipped with a radial servo speed compensation system, which distributes wear on the rubber roller more evenly and significantly extends its service life.
