Product Introduction:

The Comma-Blade Continuous Coating Machine XN-KD200 is a comma-blade continuous coating machine designed for surface coating of various substrates, with particular emphasis on the lithium-ion battery industry. The XN-KD200 is engineered to deliver coating precision and consistency comparable to production-line equipment while remaining convenient for laboratory researchers. As a result, the XN-KD200 is an ideal choice for R&D and small-batch pilot trials in lithium-ion batteries, supercapacitors, nickel batteries, and other secondary batteries.

Main Features:

• Substrate tension control with stable web transport and integrated edge-correction device
• Dual-side hot-air circulation drying oven with upper and lower air blowing for excellent drying performance
• Comma-blade metering combined with precision adjustment mechanism for high coating accuracy
• Analog-signal-controlled power heating — high-precision heating system with long service life
• PLC control with touchscreen operation — convenient and easy to use
• Optional solvent recovery and treatment module available

Compatible Battery Chemistries:

The XN-KD200 supports cathode and anode coating processes for: NCM (ternary), LFP (lithium iron phosphate), LCO (lithium cobalt oxide), LMO (lithium manganese oxide), graphite, silicon-carbon (Si-C), and other battery electrode chemistries.

Application Areas:

• Lithium-ion battery electrode R&D — comma-blade continuous coating for cathode and anode formulations (NCM, LFP, LCO, LMO, graphite, Si-C)
• Supercapacitor electrode coating
• Nickel battery electrode coating
• Other secondary battery R&D and small-batch pilot trials
• Process development and material screening for new battery chemistries
• Research institutions, universities, and corporate R&D centers requiring production-line-comparable coating quality at laboratory scale

Installation Environment Requirements:

• Machine head ambient temperature: 25–30 °C; remainder of equipment: 10–40 °C
• Machine head relative humidity: RH ≤ 35% (when coating cathode); RH ≤ 98% (when coating anode); remainder: ≤ 98%
• Power supply: Configurable according to local electrical standards; total startup power 6 kW
• Compressed air: > 5.0 kg/cm² (after drying, filtration, and pressure stabilization)

Recommended Operating Procedure:

1. Power on the XN-KD200 and verify that the PLC + touchscreen, comma-blade station, dual-layer hot-air drying oven, photoelectric edge correction, automatic tension control, unwind/rewind air-expanding shafts, and analog-signal-controlled heating system are all operating normally. 2. Connect the compressed air supply (> 5.0 kg/cm², dried/filtered/regulated) to the equipment air inlet. 3. Mount the substrate roll (aluminum foil 8–30 μm or copper foil 6–30 μm) onto the unwind 3-inch air-expanding shaft (max. Φ250 mm, max. 50 kg load). Thread the substrate through the comma-blade coating station, the dual-layer hot-air drying oven, the photoelectric edge correction at the oven exit, and onto the rewind 3-inch air-expanding shaft. 4. Configure the automatic tension control on the touchscreen for stable substrate transport. 5. Set the target comma-blade gap using the precision adjustment mechanism to achieve the desired wet film thickness (resulting in dry film thickness 20–200 μm with ±3 μm accuracy). 6. Set the target coating speed (within 0–0.5 m/min) on the touchscreen. 7. Set the target temperature for each independent oven section on the touchscreen (within ambient–150 °C, ±0.5 °C accuracy, ≤ ±2.5 °C single-section uniformity). Allow the heating system to stabilize before starting the run. 8. Verify the slurry viscosity (target 2000–12000 mPa·s) and solid content (target 20–85%) match the equipment specifications. 9. Load the coating slurry, then initiate the run; the substrate advances through the comma-blade station, dual-layer hot-air oven, edge correction system, and onto the rewind. 10. Monitor coating thickness, dimensional accuracy, edge correction, and tension during the run; the system displays alarm screens on the touchscreen if equipment faults occur, with corresponding correction guidance. 11. After the run, allow the heating system to cool, then remove the rewound roll. Clean all wetted surfaces with appropriate solvent (water or NMP, depending on the slurry system used) and dry thoroughly before the next run.

Maintenance:

• Frequently wipe the machine with a soft cloth dampened with alcohol to keep it clean
• Lubricate moving parts with oil to keep movement smooth
• If the machine will not be used for an extended period, wipe down the surface of moving components and apply a protective rust-prevention oil
• Periodically inspect screws, nuts, pins, and other fasteners across all parts of the machine to prevent loosening, avoiding equipment-quality issues and personal-safety incidents

Optional Solvent Recovery System:

The XN-KD200 supports an optional solvent recovery and treatment module for environmentally friendly operation. The module captures and processes evaporated solvent (such as NMP) from the drying oven exhaust, supporting compliance with local environmental regulations on VOC discharge. Contact our team for solvent recovery configuration options matched to your specific slurry chemistry and recovery throughput requirements.

Packaging & Storage:

The XN-KD200 ships fully assembled with the comma-blade coating station, hard-chrome-plated coating roller, dual-layer SUS304 hot-air drying oven, automatic constant-tension control, photoelectric edge correction, 3-inch air-expanding shafts (unwind and rewind), PLC + touchscreen control panel, and steel frame on caster wheels with leveling feet (~L1700 × W900 × H1100 mm, 570 kg net). Optional solvent recovery and treatment module ships separately if ordered. Install on a stable laboratory or pilot-scale production floor in a clean, dry environment with the specified ambient temperature and humidity. Connect the equipment to a compressed air supply (> 5.0 kg/cm²) and to a power supply matching local electrical standards. Disconnect the power supply when the equipment is not in active use. After each use, clean all wetted-surface components, dry thoroughly, and store the equipment in a clean, dry environment.

Safety:

For research and industrial laboratory use only. During operation, do not insert hands or any other body parts into moving components or hazardous working areas to prevent personal injury. Operation by two or more persons simultaneously is not allowed to avoid accidental injury. External (third-party) technical personnel and unauthorized persons must not disassemble the equipment under any circumstances. Always follow standard laboratory and pilot-line safety protocols when operating coating equipment with heated surfaces. Do not touch the heated drying oven, coated substrate, or hot-air ducts during operation — surface temperatures up to 150 °C can cause burns. Always wear appropriate PPE (safety glasses, chemical-resistant gloves, lab coat) when handling slurries, solvents, and coated electrodes. When working with NMP-based slurries or other regulated solvents, ensure adequate ventilation, install the optional solvent recovery and treatment module if available, and follow local regulations on solvent use, recovery, and emission. Disconnect the power supply and isolate the compressed air supply before any cleaning, maintenance, or component replacement. Allow the heating system to cool to room temperature before any cleaning or sample-handling operations. Refer to the included user manual for complete safety and operating instructions.

Note: Specifications listed above are typical and for reference only. Actual performance depends on the specific slurry chemistry, viscosity, coating thickness, drying temperature setpoints, drying length, substrate type, and ambient operating conditions — consult published literature and our technical team for guidance on specific comma-blade continuous coating-and-drying protocols.
