Durable Efficient Cardboard Slitting Machine for Paper Processing

Overview

Engineered with a dual-motor drive system and reinforced steel structure, this machine handles paperboard, corrugated sheets, and recycled pulp rolls up to 2500mm wide, making it ideal for paper mills, converting plants, and industrial recycling facilities. Its low-maintenance design and high-speed performance ensure consistent output in demanding 24/7 operations.

Features

Industrial-Grade Durability:

Solid cast iron frame (2000kg weight) with anti-vibration mounts, minimizing resonance during high-speed slitting (250m/min maximum speed).

Tungsten carbide-tipped blades (replaceable inserts) maintain sharpness for 20,000+ hours, supported by a hydraulic blade clamping system for zero slippage.

Efficient Material Handling:

Dual unwind stands (1500kg capacity each) enable continuous operation via roll changeover without stopping the machine.

Variable frequency drive adjusts speed based on material density, reducing energy use by 30% during low-load periods.

Versatile Processing Capability:

Handles paper thickness from 0.5mm (cardstock) to 15mm (triple-wall corrugated), with adjustable feed rollers for smooth material transition.

Optional embossing unit adds protective creases to slitted edges, enhancing rigidity for heavy-load packaging applications.

User-Centric Design:

Elevated control panel (1.5m height) for ergonomic operation, with color-coded indicators for quick status checks.

Modular blade chamber design allows 10-minute access for cleaning, reducing scheduled maintenance time by 40%.

Application

Paper Mills: Converts raw paper rolls into marketable widths for distribution to packaging manufacturers.

Recycling Converters: Processes baled recycled cardboard into uniform strips for re-pulping or secondary packaging use.

Industrial Packaging: Slits specialty materials like moisture-resistant paperboard for food packaging and chemical drums.

FAQ

Q: What is the minimum slitting width for paperboard?

A: 30mm, with precision adjustment in 0.5mm increments for narrow applications like label backing.

Q: How often do the blade inserts need replacement?

A: Depending on material hardness, inserts last 500-1000 hours; the machine alerts operators via the control panel when replacement is needed.

Q: Can it handle wet-strength paper used in refrigerated packaging?

A: Yes, the stainless steel contact parts and rust-resistant coating make it suitable for moisture-prone environments.
