Lithium Battery Electrode Roll to Roll Slitting Machine

Product Overview

This roll-to-roll slitting system is engineered for continuous conversion of coil materials into two or more accurately sized strips. Its single-blade rolling-cut process, paired upper and lower circular knives, and precision knife seat support clean, repeatable cuts for demanding thin-material operations. Adjustable knife engagement and speed-to-web-speed ratio give operators controlled cutting conditions rather than relying on fixed mechanical settings.

The equipment is suited to lithium battery electrode-sheet processing, metal foil conversion, optical film slitting, and other functional-film applications. It is particularly relevant where strip width, edge condition, winding stability, and material handling must be managed together in a compact production process. The adjustable 20-280 mm slitting-width range supports varied strip formats, with customization available for specific requirements.

Built around a single upright-plate structure with independent knife holders, dust-removal provision, PLC control, and HMI operation, this unit is designed for disciplined, repeatable daily use. Independent upper and lower winding-shaft tension adjustment within 50 N helps maintain controlled rewinding conditions while operators process materials from 100 to 300 micrometers thick.

Key Features

• Ultra-Fine-Grain Tungsten Steel Blades: The system uses ultra-fine-grain alloy tungsten steel slitting blades with a 100 mm diameter. This blade material is selected for high cut quality and extended working life in precision foil and film slitting duties.

• Paired Circular-Knife Cutting Geometry: Upper and lower circular knives cut against each other in a single-blade rolling-cut arrangement. The configuration provides a defined cutting interface for continuous roll material, helping support clean strip separation.

• Precision Slitting Performance: The equipment provides slitting accuracy of ±0.09 mm and a specified burr condition of ≤25 μm. These values address critical quality checks for narrow material strips where edge condition and dimensional consistency affect subsequent processing.

• Adjustable Strip Width Setup: Strip width is adjusted by changing spacer sleeves, allowing a 20-280 mm adjustment range. Multiple sets of knife sleeves are recommended for different formats, making blade-change and width-change work more convenient across recurring product sizes.

• Controlled Knife Engagement: Knife penetration is adjustable from 0.2 to 0.4 mm and displayed with a dial indicator. This gives operators a measurable mechanical reference when establishing a suitable cut for the specific material and thickness being processed.

• Adaptable Material Path: Adjustable feed and discharge angles allow the equipment to accommodate materials with different compositions and thickness values. This is useful for operations handling varied electrode sheets, metal foils, optical films, or functional-film constructions.

• Independent Winding Tension Adjustment: Automatic winding-tension control is combined with independently adjustable upper and lower shafts, each adjustable within 50 N. The arrangement supports separate tension management during rewinding instead of using one common setting for both shafts.

• Speed Ratio Adjustment: Both knife speed and the ratio between knife speed and material line speed can be adjusted. This provides practical control over the cutting relationship as material characteristics and operating conditions change.

• Independent Knife Seat and Dust Removal: A single upright-plate structure incorporates independent knife holders and a dust-removal device. The mechanical layout organizes the cutting area while addressing dust generated during the slitting process.

• PLC and HMI Operation: PLC control with an HMI interface provides a direct operating platform for the system. Operators can use the interface to manage the process with an accessible, production-oriented control arrangement.
