The slitting machine requires a stable single-phase 220VAC±10%, 50Hz/60Hz power supply with 1kW rated power. The machine must be operated with the specified ultra-fine grain tungsten steel blades and maintained within the adjustable cutting depth of 0.2-0.4mm to ensure precision and safety.
- Power Supply Requirement: The machine requires a single-phase 220VAC±10%, 50Hz/60Hz power supply with 1kW rated power.
- Blade Material Constraint: Only ultra-fine grain tungsten steel blades (Φ100mm) must be used to maintain slitting quality and service life.
- Cutting Depth Adjustment: The cutting depth must be adjusted within the 0.2-0.4mm range using the micrometer display to avoid damage to the material or blade.
- Tension Control: The upper and lower shaft tension must be independently adjusted within 50N to prevent material deformation or winding issues.
This procedure outlines the safe and precise setup and operation of the slitting machine for foil materials. It covers blade installation, width adjustment, parameter setting, and initial slitting verification.
Required Equipment: Ultra-fine grain tungsten steel circular knives (Φ100mm), Spacers for width adjustment, Micrometer for cutting depth adjustment, PLC control panel with HMI
- Install Blades
Install the ultra-fine grain tungsten steel circular knives onto the upper and lower shafts, ensuring they are securely fastened. - Set Slitting Width
Adjust the slitting width by inserting the appropriate spacers between the blades to achieve the desired dimension (20-230mm standard). - Adjust Cutting Depth
Set the cutting depth between 0.2-0.4mm using the micrometer adjustment knob, verifying the setting on the display. - Configure Parameters
Enter the desired slitting speed (up to 4m/min) and tension values (within 50N) into the PLC via the HMI interface. - Load Material
Feed the foil roll through the guide rollers, ensuring it is aligned and properly tensioned between the upper and lower shafts. - Start Slitting
Initiate the slitting process and monitor the first run for burr-free, wave-free output, adjusting the feed angle if necessary. - Verify Quality
Inspect the slit edges for burrs or waves, and confirm the width accuracy using a micrometer before full production.
What is the maximum slitting speed and how does it affect throughput for lithium battery foil?
The maximum slitting speed is 4 m/min, which is suitable for precision slitting of lithium battery foil and other functional films. This speed, combined with automatic winding tension control (independently adjustable within 50N), ensures consistent tension and high-quality edges, though throughput is limited by the need for burr-free, wave-free results.
Can the slitting width be customized for different roll sizes, and what is the standard range?
Yes, the slitting width is adjustable by replacing spacers, with a standard range of 20–230 mm and a customizable option up to 20–280 mm. This flexibility allows adaptation to various roll widths, but the actual width must be within the machine's mechanical limits and set via spacer changes.
What are the infrastructure requirements for installing this slitting machine?
The machine requires a single-phase 220VAC±10% power supply at 50Hz or 60Hz, with a rated power of 1kW. No additional high-voltage or three-phase infrastructure is needed, but the power source must be stable to maintain consistent slitting performance and tension control.
The Atomfair-FilmSlit-4576 Slitting Machine delivers precision slitting for 100–300 μm foil materials via ultra-fine grain tungsten steel blades, achieving ≤25 μm burr control at speeds up to 4 m/min. Its independent upper/lower shaft tension control (adjustable within 50N) and PLC/HMI interface support reproducible processing of lithium battery, metal foil, and optical film webs.
Positive
- Ultra-fine grain tungsten steel blades: Φ100mm blades provide excellent slitting quality and extended service life, reducing blade replacement frequency in continuous production.
- Precise burr control and width adjustment: Burr control ≤25μm and slitting width adjustable from 20–230mm (customizable to 280mm) via spacers, enabling tight tolerance for battery and optical film applications.
Trade-offs
- Limited material thickness range: Cuttable thickness is restricted to 100–300μm, so thinner or thicker foils cannot be processed without risking blade or material damage.
- Moderate maximum slitting speed: Maximum speed of 4m/min may become a throughput bottleneck for high-volume production lines, requiring careful line balancing.
