The components of the painting assembly line mainly include pre-treatment equipment, powder spraying system, spray painting equipment, oven, heat source system, electrical control system, suspension conveyor chain, etc.

The spray type multi station pre-treatment unit is a commonly used equipment for surface treatment, which uses mechanical flushing to accelerate chemical reactions to complete processes such as oil removal, phosphating, and water washing. The typical process of spray pre-treatment for steel parts is: pre degreasing, degreasing, water washing, water washing, surface conditioning, phosphating, water washing, water washing, and pure water washing. Pre treatment can also use shot blasting cleaning machines, which are suitable for steel parts with simple structures, severe corrosion, and no or little oil. And there is no water pollution.

Oven is one of the important equipment in coating production line, and its temperature uniformity is an important indicator to ensure coating quality. The heating methods of ovens include radiation, hot air circulation, and radiation hot air circulation. According to the production schedule, they can be divided into single chamber and through type. The equipment forms include straight through and bridge type. The hot air circulation oven has good insulation, uniform temperature inside the furnace, and low heat loss. After testing, the temperature difference inside the furnace is less than 30 degrees, which meets the performance indicators of advanced similar products.

Achieve drying and solidification of the workpiece. The heat source can be selected according to the specific situation of the user, such as electricity, steam, gas, or fuel. The heat source box can be determined according to the situation of the oven: placed at the top, bottom, and sides. If the circulating fan for producing heat sources is a specially designed high-temperature resistant fan, it has the advantages of long service life, low energy consumption, low noise, and small size.
