Product Description IntroductionLithium Battery Separator Coating Equipment Features 1. High-Grade Alloy Steel Wall Panels: The equipment adopts high-grade alloy steel wall panels, providing excellent stability, corrosion resistance, and durability. 2. Passive Guide Rollers: The guide rollers, with diameters of φ70mm and φ100mm, are made of high-quality aluminum alloy. The surface is anodized to HV700 with mirror finishing. Balance precision is <5 grams, dynamic balance <2.5 grams, and levelness <0.03mm/m. Designed with low inertia for optimal performance. 3. Tension Control System: Equipped with a closed-loop tension control system from Mitsubishi Corporation, Japan, ensuring reliable performance and stable tension during operation. 4. Unwinding and Rewinding Units: The unwinding and rewinding units use a shaftless cone-top automatic opening and closing structure for quick, easy, and efficient material loading and unloading. The rewinding unit features a follower contact roller structure to maintain uniform and stable tension for the rewound material. 5. Coating Unit: The coating unit adopts a sealed doctor blade chamber design with reverse kiss coating technology to ensure coating stability and controllable coating amounts. This design minimizes solvent evaporation and prevents splashing at high speeds, ensuring operator safety and environmental protection. 6. Quick-Change Coating Rollers and Doctor Blades: Both the coating screen rollers and the sealed doctor blades feature quick-change structures, reducing downtime and increasing overall work efficiency. 7. Preheating Oven Unit: The guide rollers in the preheating oven use a semi-automatic structure with an S-path design to effectively eliminate material internal stress. The inner sidewalls of the oven are made of 304 stainless steel, and heating is achieved through multi-perforated mesh plates to ensure uniform heating, meeting food-grade hygiene standards. 8. Heating Unit: The drying oven adopts a multi-zone combination structure to accommodate different coating amounts, drying zones, and curing processes. The inner walls are made of 304 stainless steel, and the nozzles feature V-shaped openings combined with multi-perforated designs to maximize drying and curing efficiency. Heat sources can be customized, including electric heating, steam heating, thermal oil heating, natural gas heating, or integration with RTO thermal energy recovery systems. 9. Cooling and Traction Unit: A double-roller cooling traction design efficiently reduces the material's surface temperature after heating, quickly restoring it to room temperature. The double-roller structure provides dual-sided cooling to prevent stress concentration in the material and ensures a stable traction state, avoiding wrinkles or stretching caused by pressure rollers. 10. Web Guiding System: To ensure stable web alignment during coating, traction, and rewinding, the equipment is equipped with more than three edge position correction units. This guarantees that the substrate remains in a controlled center position throughout the entire operation. 11. Servo Motor Drive System: All power sources utilize a servo motor and servo controller configuration to ensure smooth acceleration and deceleration without fluctuations or speed deviations, providing precise control during operation. 12. Closed-Loop Tension Control System: The equipment employs a closed-loop tension control system that utilizes tension pendulum rollers and pressure sensors for precise and tight control. The entire system forms a closed-loop structure, ensuring stable and reliable tension management. This comprehensive design ensures high precision, reliability, and safety for lithium battery separator coating applications.Machine ParametersModelProducts Width(mm)Coating methodCoatingThickness(mm)Unwind/Winding DiaSplicing MethodMax.
