The type and color of the coating can be selected according to demand, which greatly improves the practicality of the aluminum sheet coils.

[0003] However, during the spraying operation, due to the lack of effective isolation measures, the suspended paint will spread to the surroundings, thereby polluting the working environment and seriously affecting the health of the operators. Moreover, these suspended paints will settle on the surrounding facilities and solidify into blocks, which are difficult to remove. Subsequent peeling and detachment may fall on the surface of the aluminum sheet coil being sprayed, causing a serious decline in the spraying quality and affecting the color coating operation.

[0004] Therefore, in view of the lack of effective isolation measures in the above-mentioned existing color coating spraying equipment, which causes the suspended paint to diffuse outward, pollute the working environment, and affect the health of the operators, and the suspended paint will settle and solidify on the surface of the surrounding facilities, making it inconvenient to remove, and even peel off and affect the quality of the aluminum sheet coil being sprayed, a spraying equipment for a color coating production line can be designed.
