Automatic Corrugated Carton Die-Cutting Machine

The MHK-FC model is a specialized die-cutting machine for corrugated board with thicknesses ranging from 1 to 9 mm, capable of handling warped corrugated sheets smoothly.
This model features fully automatic lead-stripping and waste-ejection functions. Once the finished products exit the machine, they can move directly to the gluing stage without requiring manual stripping or waste removal by workers.
Note: This machine model is only suitable for large-scale carton manufacturing operations with high-volume production orders. (It is not recommended for high-volume factories that process small-quantity individual orders.)
* Feeding Section
- High-speed, high-precision lead-edge feeder delivers superior feeding accuracy and powerful suction without slipping, ensuring smooth transport of various corrugated board grades.
- Custom polyethylene feed rollers combined with a fence-type support structure and air-cushioning guarantee smooth feeding and accurate registration for thick or warped corrugated boards.
- Variable-frequency suction volume micro-adjustment adapts seamlessly to different corrugated board thicknesses from F-flute up to 5-ply.
- Pneumatic side push-baffles (left and right).
- Left and right baffles adjust independently or synchronously. The front sloping baffle micro-adjusts front-to-back and up-and-down to reduce weight pressure on lower sheets, enabling smoother feeding.
- Left and right side-lay gauges ensure precise lateral positioning of the corrugated sheets.
- Top and bottom pallet-height adjustment modifies settings based on board quality and thickness for enhanced stability during feeding.
- Front baffle position micro-adjusts forward and backward to align perfectly with the gripper margin size.
- Feeding step distance adjusts on the fly without stopping the machine.
* Die-Cutting Section
- Main machine frame, upper platen, and lower moving platen are constructed from high-strength ductile iron.
- Imported 40Cr crankshaft, worm gear, and worm shaft.
- Die-cutting bottom plate and chase turnover device.
- Imported torque-limiting overload protector.
- Complete set of imported anodized aluminum alloy gripper bars with positioning system; each bar features an adjustable structure.
- Imported main drive chain.
- Imported intermittent indexing unit.
- Main drive utilizes an imported pneumatic clutch and brake unit.
- Japanese SMC air-pressure detection device with low air-pressure alarm system.
- Die-cutting chase and bottom plate lock pneumatically via Japanese SMC air regulators, preventing misplacement or failure to lock the upper chase and eliminating human error losses.
- Centralized automatic lubrication system ensures adequate oil supply across all transmission components.
- Equipped with an air storage tank to maintain stable air pressure for the entire machine.
- Motorized pressure-adjustment system enables precise pressure control via the PLC touchscreen.
- Die-cutting plate attaches to the chase using a nut-and-bolt system with a centerline positioning structure, enabling fast and precise plate changes.
* Stripping Section (Three-Frame, Four-Side Stripping)
- Utilizes a three-frame stripping mechanism.
- Middle stripping plate installs via a quick centerline positioning system, allowing operators to quickly set up plates and improve job changeover efficiency.
- Lead-edge (gripper margin) waste removal device.
* Delivery Section
- Conveyor frame for paper collection and elevation protects the corrugated surface from scratches and friction during delivery (specially designed for stacking delivery, optional).
- Non-stop roller shutter auxiliary delivery device and automatic conveyor elevation frame operate alternately, counting sheet stacks and conveying them out via belts (specially designed for stacking delivery, optional).
- Electronic batch counter.
- Spring chain-tensioning adjustment device buffers the driven wheel after adjusting tension, significantly reducing inertia impact on gripper bar travel and maintaining balanced chain tension.
- Non-stop roller shutter delivery mechanism.
- High-pile delivery table features an elevating system and delivery structure that allows entire paper stacks to be wheeled out from the machine.
* Electrical Section
- Features a German Siemens 10.4-inch touchscreen interface.
- Employs German Eaton Moeller relays and pushbuttons to ensure electrical stability and reliability.
- Utilizes Japanese Omron photoelectric switches, fiber-optic sensors, encoders, and proximity sensors for precise detection and motion stability across all electrical components.
