The multi-hanger coating production line system

Configuration and Features of the Multi - Hanger Coating Production Line System

I. Equipment Configuration

1. Pre - treatment Equipment

   • Spray Pre - treatment Unit: Used for degreasing, phosphating, and water - washing processes. Typical processes include pre - degreasing, degreasing, water - washing, surface adjustment, phosphating, and deionized water - washing. This equipment uses mechanical flushing to accelerate chemical reactions, ensuring workpiece surfaces are clean.

   • Shot Blasting Machine: Suitable for simple - structured steel parts with severe rust, little or no oil. It effectively removes surface impurities without water pollution.

2. Powder Spraying System

   • Electrostatic Powder Spraying Equipment: Utilizes high - voltage electrostatic principles to evenly coat workpieces with powder coatings. Key components are recommended to be imported to ensure spraying quality.

   • Recovery Device: Uses a small cyclone + filter - core recovery device for fast color - changing and high recovery efficiency.

3. Paint Spraying Equipment

   • Oil - Spray Booth: Suitable for surface coating of various workpieces, effectively capturing paint mist to reduce environmental pollution.

   • Water - curtain Spray Booth: Captures paint mist through a water curtain to purify the spraying environment.

4. Curing Equipment

   • Curing Oven: Uses hot - air circulation, radiation, or a combination of radiation and hot - air circulation for even curing of coatings. The oven design follows advanced foreign concepts to ensure uniform and stable oven temperatures.

5. Conveying Equipment

   • Suspension Conveying Chain: Combines overhead suspension with ground - level skid conveyance for smooth, fast, and convenient operation. Workpieces are hung on dedicated hangers, and the transfer through switches is smooth, meeting the automatic conveying requirements of workpieces at various treatment stations.

6. Electrical Control System

   • PLC Control: Uses a programmable logic controller (PLC) to achieve automated control, programmable according to production process requirements, and implements centralized monitoring via a fieldbus.

7. Exhaust Gas Treatment Device

   • Exhaust Gas Treatment Equipment: Uses a design with a labyrinth filter or a combination of honeycomb paper + paint - arresting mesh (coir fiber) + coarse - efficiency filter + medium - efficiency filter bag to treat exhaust gases generated during the spraying process.

II. Equipment Features

1. High - efficiency Automation: The entire production line operates automatically, saving human resources and increasing production efficiency.

2. Multi - hanger Design: Multiple hangers can accommodate different types of workpieces simultaneously, enhancing the flexibility and utilization rate of the production line.

3. Stable Conveying System: Uses multi - tiered hangers and a powerful conveying system to ensure smooth transfer of workpieces between processes.

4. Energy - saving and Efficient: The curing oven uses fuel - or gas - fired hot - air circulation technology, saving energy and ensuring uniform temperature.

5. Strong Adaptability: The conveying speed and spraying parameters can be adjusted according to the size and shape of different workpieces.

6. Environmental - friendly and Safe: Uses dust - proof, isolated, and ventilated designs to reduce dust and solvent evaporation, enhancing production safety.

7. Cost - effective: By optimizing the coating process, up to 60% of the coating material can be saved.

8. Intelligent Control: With the development of industrial internet technology, automated coating production lines are gradually achieving intelligent control. Data analysis and optimization improve production efficiency and product quality.

9. Modular Design: The system uses modular design, allowing flexible configuration and large - scale customized production according to actual needs.

The multi - hanger coating production line system, with its rational configuration of pre - treatment, spraying, and curing equipment combined with efficient conveying and control systems, achieves automated and continuous coating operations. It features high efficiency, high quality, energy - saving, and environmental - friendly characteristics and is widely used for surface coating of various workpieces.
