Roll to Roll Continuous Slitting Machine

Product Overview

This roll-to-roll continuous slitting machine is designed for precision conversion of coil materials into two or more continuous narrow strips. Its single-blade rolling-cut process uses matched upper and lower circular knives to produce controlled slit edges on thin foil and film. Adjustable blade engagement, replaceable spacer sleeves, and precision knife holders give operators a practical platform for repeatable width setup.

The equipment is suited to lithium battery foil processing, metal foil conversion, optical film preparation, and other functional-film applications. It supports materials from 100 to 300 μm thick and offers an adjustable slitting-width range of 20 to 480 mm. The system is particularly relevant where downstream winding, coating, lamination, or cell-manufacturing processes depend on clean, stable slit material.

Built around ultrafine-grain tungsten carbide cutting blades, independent knife-holder construction, servo-controlled tension, and PLC/HMI operation, this unit is configured for demanding production and research environments. Automatic winding-tension control and web-guiding control at unwinding help maintain orderly material handling, while the specified slitting accuracy and burr limit support consistent process quality.

Key Features

• Ultrafine-Grain Tungsten Carbide Blades: The circular slitting blades use ultrafine-grain alloy tungsten carbide and have a diameter of Φ100mm. This blade material is specified for high slitting quality and long service life when processing foil and film materials.

• Matched Upper and Lower Circular Knife Design: Upper and lower circular knives perform opposed cutting for controlled material separation. The rolling-cut arrangement supports continuous multi-strip processing from roll-stock material.

• Precision Slit Quality: The equipment delivers a stated slitting accuracy of ±0.09mm and burr condition of ≤15μm. These specifications help buyers assess suitability for material formats where edge quality affects subsequent handling and processing.

• Adjustable Slitting Width Setup: Slitting widths are set by changing spacer sleeves between the knife assemblies. The adjustable range is 20 to 480mm, and customized width capability is available for process-specific material layouts.

• Adjustable Blade Engagement: Knife penetration is adjustable from 0.2 to 0.4mm and displayed by a dial indicator. This gives operators a defined method for setting blade engagement according to material characteristics and processing requirements.

• Adaptable Material Entry and Exit Geometry: Infeed and outfeed angles can be adjusted to accommodate materials with different properties and thickness values. This capability supports setup flexibility across the stated foil and film application categories.

• Independent Knife-Holder Construction: A single upright-plate structure with independent knife holders provides an organized cutting arrangement. The configuration is designed around accessible width adjustment through spacer replacement.

• Servo-Controlled Web Tension: Unwinding and rewinding tension are controlled by servo motors. Automatic winding-tension control is provided, with the upper and lower winding shafts independently adjustable within 50N.

• Controlled Roll Handling: The system uses two differential winding shafts for rewinding and web-guiding control for unwinding. These functions support orderly roll transport throughout continuous slitting operations.

• PLC and HMI Operation: PLC control with an HMI interface provides a direct operating method for setup and process control. The control arrangement is intended to make routine operation convenient and straightforward.
