Product Introduction

The first domestically developed and successfully launched machine has been widely adopted in the new energy industry. Equipped with proprietary technology, its overall performance exceeds that of imported shearing machines.

Notable Clients: Our technology is utilized by industry leaders including ATL, BYD, BAK, CATL, Yiwei, and over 200 other battery manufacturers worldwide.

Advantages: In addition to standard lithium electrode cutting, this machine offers exceptional precision for lithium iron phosphate (LiFePO4) electrodes and both ultra-thin and ultra-thick power battery electrodes.

Equipment Overview

Purpose: Designed for continuous cutting and rewinding of intermittent coating electrodes, copper foil, aluminum foil, and isolation films.
Unfolding System: Pneumatic shaft with magnetic powder brake, constant tension control, and photoelectric edge alignment.
Windup System: Custom sliding shaft ensures uniform tension and synchronization, eliminating breakage. Adjustments are managed via touch screen.
Modular Blade Holder: Mobile cart design allows for rapid mechanical positioning and fast blade changes for varying widths.
Advanced Drive: Features servo-motor traction and Mitsubishi inverter-controlled rewinding via PLC programming.
Blade Technology: Globally leading roller shear blades ensure edges are completely free of burrs.

Frequently Asked Questions (FAQ)

What materials can this machine process?

The machine is designed for continuous cutting and rewinding of lithium-ion battery electrodes (positive/negative), copper foil, aluminum foil, isolation films, and aluminum-plastic films.

How does the machine prevent material breakage during winding?

It utilizes a custom-designed sliding shaft that ensures uniform tension and synchronization across all strips. Tension is automatically tracked and adjusted via a PLC and touch screen interface.

What is the cutting precision and quality?

The machine offers high cutting width accuracy (≤ ±0.3mm) and advanced roller shear blades that produce edges completely free of burrs (Vertical direction ≤ 6um).

Can the machine handle different production widths?

Yes, it features a modular blade holder installed on a mobile cart, which supports rapid mechanical positioning and fast blade changes for different widths.

Is the equipment suitable for high-intensity industrial use?

Absolutely. It is designed for 24/7 continuous operation with a design life cycle of no less than 10 years and a very low equipment failure rate (≤ 1%).
