What equipment does the complete painting assembly line include?

The entire painting assembly line includes pre-treatment equipment, powder spraying system, painting equipment, oven, heat source system, electrical control system, suspension conveyor chain, etc.

1. Pre processing equipment

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.

2. Powder spraying system

The small cyclone and filter recovery device in powder spraying is an advanced and fast color changing powder recovery device. It is recommended to use imported products for the key parts of the powder spraying system, and to localize all components such as the powder spraying room and electric mechanical lift.

3. Spray painting equipment

Such as oil spray paint booth and water curtain paint booth, widely used for surface coating of bicycles, automotive steel plate springs, and large loaders.

4. Oven drying

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 ± 3 ° C, which meets the performance indicators of similar products in advanced countries.
