Roll To Sheet Electrode Cutting Machine

Roll to Sheet Electrode Cutting Machine – Automatic Lithium Battery Electrode Slitter

The Roll to Sheet Electrode Cutting Machine is an advanced automated system designed for precision cutting of lithium-ion battery electrodes. It converts roll-fed electrode materials into individual sheets with high accuracy and consistency, significantly improving production efficiency and reducing labor intensity.

Working Principle:

The machine utilizes a stepper motor for fixed length loading, ensuring precise and repeatable cutting lengths. A pneumatic control system manages pressure calendering and slicing operations. For coated electrodes with gaps, a color code sensor automatically identifies the gaps and performs selective cutting. The unwinding system features magnetic powder tension control and air expansion shaft for smooth material handling.

Key Features:

• High Precision Cutting: Stepper motor drive ensures accurate fixed-length cutting.
• Automatic Gap Recognition: Color sensor identifies coated/uncoated areas for selective cutting.
• Excellent Burr Control: Vertical burr ≤15μm, horizontal burr ≤30μm for high-quality edges.
• Wide Material Compatibility: Handles both cathode and anode electrodes up to 500mm width.
• Adjustable Parameters: Cutting speed 30–300mm/s, multiple cutting methods available.
• User-Friendly Operation: Simple controls reduce worker fatigue and increase efficiency.
• Versatile Cutting Methods: Supports fixed length cutting, gap 1 cutting, and gap 2 cutting.

Cutting Methods:

• Fixed length cutting
• Gap 1 cutting (single gap recognition)
• Gap 2 cutting (double gap recognition)

Applications:

• Lithium-ion battery electrode sheet production
• Polymer battery electrode cutting
• Gap coated electrode processing
• Battery manufacturing R&D and pilot production
