Product Introduction

Product Details

This medium lithium battery coating machine is designed for mid-sized lithium battery production operations. Integrating various coating techniques, it enables the high-precision, uniform application of cathode and anode slurries. Furthermore, it features advantages such as stable tension control, high drying efficiency, and intelligent data monitoring, thereby helping to enhance both the quality of lithium battery electrode sheets and overall production efficiency.

Product Features

1. Simple Unwinding Operation: The material roll is supported by an air-expanding shaft, facilitating quick and convenient roll changes while ensuring uniform tension and precise centering. The built-in ultrasonic sensor within the web guiding controller enables automatic web alignment, effectively preventing product quality defects caused by uneven material alignment.

2. Automatic Tension Control: Utilizes a magnetic powder brake system integrated with a tension controller to minimize manual labor requirements.

3. Multiple Coating Methods: This medium lithium battery coating machine Features a combination of doctor blade metering transfer coating and a reverse-roll transfer coating mechanism, achieving a blend of high-precision coating and superior product aesthetics. The pneumatic quick-lift roller mechanism, paired with a servo-driven roller gap adjustment system, offers versatile options for both precise continuous coating and intermittent coating applications.

4. Synchronous Speed Control: Employs vector variable-frequency drive technology to precisely regulate tension across each section of the machine while ensuring the synchronized operation of all mechanical components.

5. Multiple Heating Options: Depending on the specific solvent types used by the customer, various heating methods-such as electric heating tubes, far-infrared radiation, or microwave heating-are available to effectively enhance heating efficiency. The drying oven length can be configured in various ways to match the customer's production capacity, thereby maximizing the return on investment.

6. Lamination Mechanism: Equipped with an automatic Web Guiding System (EPC) positioned prior to the lamination stage-including a dedicated system for the second unwinding station-to ensure the utmost accuracy and precision throughout the lamination process. The professional design of the lamination mechanism guarantees a flat, smooth, and defect-free laminated product.
