Product Introduction
Rvaxb-02/300 Micro Concave Wire Rod Coil Coating Machine is a precision coating machine with an effective coating width of 300mm, which integrates automatic unwinding, feeding, wire rod/micro-concave scraping, drying, correction and winding functions in one of the technical requirements, performance parameters, structure and configuration. The equipment is designed for laboratory research and development or small-batch production, suitable for the preparation of high-precision coating materials such as slurries, adhesives, optical films, etc., requiring stable operation, uniform coating, and precise control.
Overall technical requirements
Equipment Use: Used for precise and uniform wet film coating and drying on flexible substrates such as film, paper, and metal foil.
Operating mode: Continuous roll-to-roll production.
Design concept: modular design, ergonomic operation, perfect safety protection, easy maintenance and cleaning.
Control core: Integrated control with industrial PLC and high-precision servo system, equipped with color touch screen (HMI) human-machine interface.
Key indicators: high uniformity of coating thickness, good drying effect, stable tension control, neat unwinding and unwinding.
Assistive systems
Pneumatic system: Provide air source for correction, scraper lifting, belt splicing and other actions, working pressure 0.5-0.7 MPa.
Exhaust system: Exhaust duct interface (Φ150mm) is equipped at the top or tail of the oven.
E-stop: Install an E-stop button.
Performance and accuracy metrics
Coating uniformity (CV value): ≤ 3% (dependent on slurry properties and process optimization).
Drying effect: After the substrate leaves the oven, the coating should be surface dry or solid, without residual solvent (according to the process requirements).
Rewinding neatness: End face staggered ≤ ±1 mm.
Repeatable positioning accuracy: Each servo axis is accurately positioned.
Noise: The device operates normally with noise ≤ 75 dB(A).
Safety and environmental protection requirements
Electrical safety: grounding protection, short circuit protection, overload protection, insulation protection.
Exhaust gases: The oven exhaust vent can be connected to the external ventilation duct.
Material: Corrosion-resistant materials (e.g., SUS304 stainless steel) for the part in contact with the slurry.
