The on - line planar reciprocating coating line is an automated device commonly used in industrial production for the surface coating of planar workpieces. It is widely applied in industries such as furniture manufacturing, electronic device housing production, and building decoration material processing, aiming to enhance the decorative, corrosion - resistant, and wear - resistant properties of the workpiece surface. The following is a detailed introduction:
Conveying System: Usually composed of motors, reducers, chains, guide rails, etc., it is used to carry and transport workpieces to run continuously on the coating line. This ensures that workpieces pass through each coating process in sequence at a set speed and direction.
Reciprocating Spraying Mechanism: This is the core component of the coating line, mainly including spray guns, spray rods, and drive devices. The spray guns are installed on the spray rods, and the drive device enables the spray rods to move reciprocally within a plane, thus achieving uniform spraying on the workpiece surface. The number, spacing, and spraying angle of the spray guns can be adjusted according to the size of the workpiece and coating requirements.
Paint Supply System: It includes paint storage tanks, pumps, filters, flow meters, etc. Its function is to extract the paint from the storage tank, filter and measure it, and then deliver it to the spray guns, providing a stable supply of paint for spraying. According to different coating processes, the paint supply system can also switch between multiple types of paint.
Drying System: Generally, hot - air circulation drying or infrared radiation drying methods are adopted. After the workpiece is sprayed, the drying system can quickly volatilize the solvent in the paint, allowing the paint to cure into a film. The drying temperature and time can be precisely controlled according to the characteristics of the paint and the material of the workpiece.
Control System: Composed of an electrical control cabinet, programmable logic controller (PLC), sensors, etc., it is responsible for monitoring and regulating the operation of the entire coating line. Operators can set parameters such as conveying speed, spraying reciprocating frequency, and drying temperature through the control system to ensure the stability and consistency of the coating process.
First, the workpiece is placed on the chain or guide rail of the conveying system through the loading device, and the conveying system drives the workpiece to move forward slowly.
When the workpiece reaches the spraying area, the reciprocating spraying mechanism starts to work. The spray rod moves reciprocally along the plane of the workpiece under the action of the drive device, and at the same time, the spray gun sprays a uniform mist of paint, covering the surface of the workpiece to form a wet paint film.
The sprayed workpiece continues to enter the drying system with the conveying system. Under suitable temperature and air - flow conditions, the solvent in the paint volatilizes rapidly, and the film - forming substances such as resin undergo cross - linking reactions, causing the paint film to cure and form a coating with certain hardness and gloss.
Finally, the workpiece that has passed through the drying and curing process is removed from the coating line through the unloading device, completing the entire coating process.On - line painting line,On - line reciprocating coating line,On - line reciprocating spraying line,Coating assembly line
High Efficiency: It can achieve continuous and automatic coating of workpieces, greatly improving production efficiency and reducing the time and labor intensity of manual operations.
Uniformity: The reciprocating spraying mechanism can accurately control the movement trajectory and spraying parameters of the spray gun, ensuring a uniform coating thickness on the workpiece surface and improving the coating quality.
Flexibility: It can flexibly adjust parameters such as conveying speed, spraying reciprocating frequency, and the number of spray guns according to the size, shape, and coating requirements of different workpieces, adapting to various production needs.
Environmental Friendliness: It is equipped with advanced paint mist collection and treatment devices, which can effectively reduce paint mist emissions, minimize environmental pollution, and improve the working environment.
The on - line planar reciprocating coating line, with its characteristics of high efficiency, precision, flexibility, and environmental friendliness, provides an ideal solution for the surface coating of planar workpieces and plays an important role in modern industrial production.
