Automatic-Feed Carton Slotter
The Automatic-Feed Carton Slotter is engineered for high-efficiency slotting, creasing, and corner-cutting of corrugated cardboard sheets. Designed for corrugated box plants and packaging converters, this machine processes single, double, and triple-wall boards (Flutes A, B, C, E, AB, BC) into precision carton blanks.
Description
The Automatic-Feed Carton Slotter is engineered for high-efficiency slotting, creasing, and corner-cutting of corrugated cardboard sheets. Designed for corrugated box plants and packaging converters, this machine processes single, double, and triple-wall boards (Flutes A, B, C, E, AB, BC) into precision carton blanks.
Built on a rigid, stress-relieved cast iron and heavy steel plate framework, it delivers stable mechanical registration at speeds up to 120 sheets/min. Integrated vacuum suction feeding and pneumatic side-register guides ensure accurate board transfer without surface crushing.

Key Features
Vacuum Suction Feeding System: Employs high-pressure centrifugal blowers with frequency-inverter air volume control to feed warped or heavy-weight corrugated boards smoothly.
Synchronized Phase Adjustment: Planetary gear-driven slotting phase units allow 360-degree electrical adjustment while running or stopped, reducing setup time between job orders.
Tungsten Alloy Slotting Knives: Heat-treated alloy steel blades maintain sharp cutting edges through extended runs of high-grammage kraft linerboards, producing clean cuts without flute crushing.
Pneumatic Order Storage & Shift: Optional PLC-based touch screen control stores up to 99 routine box dimensions, automatically repositioning slotting heads and creasing wheels via precision ball screws.
Auto-Lubrication Circuit: A closed-loop oil pump continuously lubricates primary drive gears, minimizing thermal expansion and mechanical wear during multi-shift operations.
Applications
Regular Slotted Containers (RSC): High-volume production of standard shipping cartons for logistics, electronics, and appliance industries.
Heavy-Duty Industrial Packaging: Processing heavy double and triple-wall boards for automotive parts and machinery export crates.
Die-Cut & Special Layout Blanks: Slotting and creasing complex folding box layouts requiring multi-knife registration.
Configuration & Customization
Feeding Unit:
Choose between Lead-Edge Feeder (ideal for warped or heavy boards) or Roll-Feed Suction.
Tooling Configuration:
Standard setup includes 4 slotting knife assemblies and 1 corner-cutting knife assembly; additional slotting heads can be added for multi-panel boxes.
Electrical Standards:
Configured for local plant voltage requirements (380V/50Hz/3Ph, 415V/50Hz/3Ph, or 480V/60Hz/3Ph) utilizing Schneider or Siemens low-voltage switchgear.
Control Interface:
Standard button console with digital phase counters, or upgraded PLC touch-screen HMI with job recipe memory.
Quality Control & Manufacturing
Plate Cutting & Annealing: Main frame structural plates are laser-cut from Q345B carbon steel and undergo high-temperature annealing to eliminate residual internal stress, preventing bed distortion under continuous dynamic load.
CNC Boring & Milling: Frame side panels and gear housings are machined in a single clamping setup on large CNC floor borers to guarantee shaft parallelism within 0.02 mm.
Gear Hobbing & Grinding: Drive gears are forged from 20CrMnTi alloy steel, carburized, quenched to HRC 58-62, and precision ground (Grade 6 accuracy) for low noise and backlash-free transmission.
Factory Run-Off Testing: Every machine undergoes a strict 8-hour continuous no-load and loaded test run using standard test board stock to verify registration tolerance, thermal stability, and electrical safety before crating.
