High-Performance Hanging Conveyor System for Multi-Color Spraying in Automotive Furniture and Electronic Industries

Equipment Description:

1. Equipment Overview ‌
Multi-color spraying line is an automated coating equipment, suitable for multi-color spraying needs on metal, plastic, wood products and other surfaces, supporting fast color change, high-precision spraying and efficient production. It is widely used in automotive parts, home appliances, furniture, electronic products and other industries.

‌2. Core process flow ‌
‌Feeding ‌ → ‌Pretreatment (cleaning/degreasing/phosphating) ‌ → ‌Moisture drying ‌ → ‌Primer spraying ‌ → ‌Color paint spraying (multi-color switching) ‌ → ‌Varnish spraying ‌ → ‌Curing and drying ‌ → ‌Cooling ‌ → ‌Detection/unloading ‌

3. Additional functions (optional configuration) ‌
‌Visual recognition system ‌: Automatically identify the shape/color of the workpiece and adjust the spraying path. ‌Automatic cleaning module ‌: Automatically clean the spray gun and pipes after color change. ‌3D simulation software ‌: Offline programming and spraying effect simulation.

4. Selection Recommendations‌
‌Automotive industry‌: Prioritize high-precision robots + water-based paint systems.
‌Furniture industry‌: Equipped with high-flow spray guns + UV curing equipment.
‌Small batches and multiple varieties‌: Modular design supports rapid model change.

Main structures and components:

‌‌1. Pre-treatment equipment‌
‌Function‌: Remove oil and dust from the workpiece surface and enhance coating adhesion.
‌Key components‌: Spray cleaning tank (alkaline/acid solution)
Ultrasonic cleaning machine (precision parts)
