Guangdong hongma coating equipment Co., Ltd. is a professional production of various types of coating equipment company specialized in R & D. Our company specializes in manufacturing 20 years, advanced product technology, quality warranty for 2 years, is unmatched in the industry. Because I can, I can! The structure of us painting production line from which parts: coating equipment mainly consists of pre-treatment electrophoresis line (electrophoresis paint is water-based paint, the earliest development of its main feature is the coating of high efficiency, economic security, less pollution, can realize the automation of management. The need for pretreatment before coating, electrophoresis paint) to form the sealing bottom coating line, coating line, coating line, finishing line and drying system. Coating production line workpiece conveying system adopts mechanical transmission mode of air suspension and ground skid combination, stable operation, fast and convenient, using PLC control programming, according to the actual requirements of the production process, monitoring the implementation of programming control fieldbus, automatic switching operation division.
Design of painting production line of each drying system according to the design concept and parameters of foreign countries, the oven chamber body adopts bridge structure (sealing primer, furnace except) to ensure the temperature uniformity and stability, improve the efficiency of the heat of the heating device; the introduction of foreign advanced products, imported burner and control the test system, the drying system is running well stable, smooth continuous temperature curve.
Painting production line is mainly composed of pretreatment line, bottom sealing electrophoresis coating line, coating line, coating line, finishing line and drying system.
Two, coating production line components
The seven components of coating line include pretreatment equipment, powder spraying system, spray painting equipment, oven, heat source system, electric control system, suspension conveyor chain and so on.
Pretreatment equipment
Spray type multi station pretreatment unit is a common equipment for surface treatment. The principle is to use the mechanical erosion to accelerate the chemical reaction to complete the process of degreasing, phosphating and washing. The typical process of spray pretreatment of steel parts is: pre degreasing, degreasing, washing, washing, surface conditioning, phosphating, washing, washing and pure water washing. Pre treatment can also use shot blasting machine, suitable for simple structure, serious corrosion, no oil or less oil steel parts. And no water pollution.
Dusting system
The small cyclone + filter cartridge recovery device in powder spraying is an advanced powder recovery device with fast color change. The key part of the powder injection system recommends the use of imported products, such as powder spraying room, electric mechanical elevator and so on.
Painting equipment
Such as oil spray paint room, water curtain spray chamber, widely used in surface coating of bicycle, automobile steel plate spring, large loader.
Oven
Oven is one of the important equipments in coating production line, and its temperature uniformity is an important index to guarantee the quality of coating. Oven heating methods are: radiation, hot air circulation and radiation + hot air circulation, etc., according to the production program can be divided into single room and through type, etc., the form of equipment has straight through and bridge. The hot air circulation oven has good thermal insulation, uniform temperature and little heat loss in the furnace. After testing, the temperature difference in the furnace is less than + 3oC, reaching the performance index of similar products in advanced countries.
Heat source system
Hot air circulation is a more common heating method. It uses the convection conduction principle to heat the oven,
Mobile phone coating production line
To achieve drying and curing of the workpiece. The heat source can be selected according to the specific conditions of the user: electricity, steam, gas or fuel oil, etc.. The heat source box can be determined according to the condition of the oven: at the top, bottom and side. The circulation fan which produces heat source, such as specially made high temperature fan, has the advantages of long service life, low energy consumption, low noise and small volume.
Electronic control system
There are centralized and single column control for the electrical control of painting and coating line. Centralized control can use programmable logic controller (PLC) to control the host, according to the preparation of the control procedures for automatic control of each process, data acquisition and monitoring alarm. Single row control is the most commonly used control method in coating production line. Each process is controlled by single row. The electric control box (cabinet) is set near the equipment. The cost is low, the operation is visual and the maintenance is convenient.
Suspension conveyor chain
The suspension conveyor is the conveying system of industrial assembly line and coating line, and the suspension type suspension machine is applied to the storage shelf of L=10-14M and the coating line for special-shaped street lamp and alloy steel pipe. In the special workpiece hoisting rack (bearing 500-600KG), and smooth switch, switch according to working instruction by the electrical control of opening and closing, meet the automatic conveying workpiece in each treatment station, in the cold room, under a strong regional parallel stacking cooling, and in the cold region is provided with hanging identification and traction alarm stop device.
