Products Description
The fully automatic powder coating production line is a coating production line that integrates automation and intelligence, specifically designed for efficient and uniform powder coating treatment of workpieces. Here is a detailed introduction:
1、 Definition and Function
definition:
Fully automatic powder coating assembly line, also known as automatic spray coating assembly line, is a production line that completes the entire process of powder coating on the surface of workpieces through automated equipment. It integrates pre-processing, powder coating, curing, cooling, and unloading processes to achieve unmanned or less manned operations, significantly improving production efficiency and coating quality.
Core functions:
Automatic loading and conveying: The automatic loading, positioning, and circulation of workpieces are achieved through equipment such as hanging chains, ground rails, or robots.
Precise powder spraying: Using a high-voltage electrostatic generator to make the powder coating charged and evenly adsorbed on the surface of the workpiece, forming a dense coating.
Efficient curing: The powder is melted, leveled, and cured through a high-temperature oven (160-210) to ensure coating adhesion and corrosion resistance.
Powder recycling and circulation: equipped with a multi-stage recycling system (such as cyclone separation and filter element filtration), reducing powder waste and lowering production costs.
Intelligent control: using PLC or industrial computer control system to achieve precise control of spraying parameters (such as spraying volume, speed, temperature).
2、 Application Fields
The fully automatic powder coating assembly line is widely used in industries with high requirements for coating quality, efficiency, and environmental protection, including:
Automotive industry: Spray paint body, bumper, wheel hub and other components to provide corrosion-resistant and scratch resistant coatings.
Home appliance manufacturing: Processing refrigerators, washing machines, and air conditioning casings to enhance appearance and durability.
Furniture industry: Spray metal furniture and wooden products (such as tables, chairs, and cabinets) to achieve rust and scratch resistant effects.
Building materials field: Processing doors and windows, aluminum profiles, and wrought iron products to meet high-precision and uniformity requirements.
Hardware and metal processing: spraying tools, equipment casings, suitable for surface treatment needs of complex shaped workpieces.
3、 Working principle
The core working principle of the fully automatic powder spraying assembly line is based on electrostatic adsorption and hot melt solidification:
Electrostatic adsorption:
The spray gun is connected to the high-voltage negative electrode, and the workpiece is grounded to form a positive electrode, creating an electrostatic field.
The powder coating is sent from the powder supply bucket to the spray gun through the powder conveying pipe, and after being charged, it is uniformly adsorbed on the surface of the workpiece.
Hot melt curing:
The workpiece enters the high-temperature oven, and the powder melts and flattens at 160-210, forming a dense coating.
The curing furnace adopts an intelligent temperature control system to ensure temperature uniformity and avoid coating defects.
4、 Technical advantages
Efficient production:
Automated processes shorten production cycles and increase production capacity (3-5 times more efficient than traditional manual spraying).
Precise control:
The intelligent system realizes quantitative and fixed-point control of spraying volume and trajectory, with uniform coating thickness (error ≤± 5 μ m).
Cost optimization:
The powder recovery rate is over 98%, reducing raw material waste.
Quality improvement:
The electrostatic adsorption process enhances the adhesion of the coating and improves its corrosion resistance compared to traditional spray painting.
Environmental protection and energy conservation:
No solvent volatilization, VOCs emissions are close to zero; Intelligent temperature control reduces energy consumption (saving 20% -30% energy compared to traditional ovens).
Strong adaptability:
Capable of handling complex shaped workpieces (such as surfaces and grooves) to meet diverse production needs.
5、 Typical case
Automotive industry: After adopting a fully automatic powder coating assembly line, a certain car company has increased the qualification rate of body painting from 85% to 98%, and the annual production capacity of a single line has reached 200000 vehicles.
In the field of household appliances, a refrigerator factory has extended the salt spray resistance test time of the shell coating to 1000 hours through assembly line optimization, far exceeding industry standards.
summarize
The fully automatic powder spraying assembly line achieves efficient, precise, and environmentally friendly coating production through integrated automation and intelligent technology. It is widely used in industries such as automobiles, home appliances, and furniture, which not only improves production efficiency and product quality, but also reduces costs and environmental impact. It is an important development direction in the field of modern industrial coating.
