Polymer Battery Lithium Battery Positive Negative Electrode Sheet Electric Slitting Machine

Product Overview

This electric roll slitting system is designed for precision cutting of polymer battery and lithium battery positive and negative electrode sheets. It uses opposed upper and lower circular cutters to separate electrode material into controlled widths from 10 to 300 mm. Adjustable material guidance, adjustable cutter engagement, and a knob-controlled low-speed drive give operators direct control over positioning and the cutting process.

The equipment is suited to electrode-sheet preparation where accurately slit strips are required before subsequent battery-cell production steps. Its working range covers battery electrode sheets with a thickness of 50-400 μm, making the unit relevant to polymer battery work and lithium battery positive and negative electrode processing. The standard knife-spacing arrangement supports repeatable strip layouts, while alternative spacing can be selected when the process requires it.

Built around synchronized upper and lower cutter transmission, the system is intended for stable, reliable slitting under controlled operating conditions. An acrylic cutter guard, open-type cutter fixing arrangement, accessible handwheel adjustment, and serviceable mechanical construction support safe operation, routine maintenance, and dependable long-term use.

Key Features

• Adjustable Infeed Positioning: An adjustable guide device locates incoming electrode material before it reaches the cutting zone. This supports consistent feeding alignment and helps the operator establish the required material position for each slitting job.

• Electric Roll Slitting Principle: The equipment uses an electrically driven roll-cutting method with upper and lower circular knives operating as a matched cutting pair. This configuration is purpose-built for controlled separation of thin battery electrode sheets rather than hard metal slitting.

• Synchronized Upper and Lower Cutters: The upper and lower blades run at the same speed through synchronized transmission. Coordinated blade movement provides a stable cutting action and is a key foundation for reliable slitting performance.

• Handwheel-Adjustable Cutter Engagement: Cutter engagement is adjustable by handwheel from 0.2-0.4 mm. This allows operators to set the knife penetration for the electrode-sheet material and working condition, supporting process control without changing the basic machine configuration.

• High-Precision Circular Knife Arrangement: The opposing circular knives have an 85 mm diameter and use ultrafine-grain alloy steel cutting material. Steel knives and rubber knives are arranged alternately in the principal upper and lower cutter assembly to support the intended electrode-sheet slitting process.

• Configurable Strip Spacing: The supplied knife-spacing configuration is 56 mm, 56 mm, 56 mm, 58 mm, and 58 mm, 58 mm. Other spacing arrangements are available as options, allowing the cutting layout to be selected around the strip-width requirements of the application.

• Open Cutter Mounting: An open-type cutter fixing method simplifies cutter removal. This practical mechanical arrangement improves access when the cutter assembly needs to be removed for cleaning, inspection, maintenance, or process-related changes.

• Controlled Slitting Speed: Slitting speed is below 2 m/min and is adjustable by knob. The low-speed adjustable drive allows the operator to regulate the working pace while monitoring feed positioning and cutter operation.

• Protected Cutting Area: An acrylic protective device is fitted at the rolling-cutter area. The guard provides a physical protective barrier around the working cutter zone and reinforces the requirement to keep hands away from the cutters during operation.

• Service-Oriented Mechanical Construction: The unit incorporates upper and lower rolling cutters, cutter supports, infeed and outfeed positioning plates, gears, a reducer, motor, and frame. Its construction allows routine cleaning, lubrication of linear guide-rail moving parts, and fastening checks to be carried out as part of disciplined upkeep.

Technical Specifications

Why Choose This Product

• Purpose-Built Electrode Processing: This system is specified directly for polymer battery and lithium battery positive and negative electrode sheets, with a 50-400 μm cuttable thickness range and 10-300 mm cutting width range. Buyers can evaluate suitability against clear electrode-material requirements rather than relying on a general-purpose cutting claim.

• Controlled Mechanical Accuracy: Adjustable infeed guidance, handwheel-controlled cutter engagement, and synchronized equal-speed cutter transmission work together to support precise, reliable slitting. These are practical controls for maintaining a consistent cutting setup across production or development tasks.

• Durable Cutting Components: The 85 mm circular cutters use ultrafine-grain alloy steel, and the cutter assembly is designed around alternating steel and rubber knives. The equipment should be maintained by keeping cutter surfaces clean, lubricating linear guide-rail moving parts, and protecting cutter surfaces with rust-preventive oil during extended non-use.

• Practical Serviceability and Safety: Open-type cutter fixing provides access for cutter removal, while the acrylic guard protects the cutter area during operation. Regular checks of screws, nuts, pins, and other fasteners help prevent loosening and support dependable equipment condition.

• Configurable for Strip Requirements: The standard knife-spacing layout combines 56 mm and 58 mm positions, with other intervals available as options. This allows the slitting arrangement to be aligned with the required electrode-strip layout while preserving the same core machine platform.
