The ones still in use include three types: aluminum veneers, aluminum-plastic composite panels, and aluminum honeycomb panels. Among these three materials, the most commonly used are aluminum veneers and aluminum-plastic panels. Aluminum veneers are obtained by processing aluminum plates with a certain thickness through sheet metal processing, and then a fluorocarbon coating is applied to the semi-finished product to improve the overall performance of the aluminum veneer. The traditional application of fluorocarbon coating on aluminum veneers is often achieved by manual spraying, which has high labor costs. At the same time, paint spillage is likely to occur during spraying, and the environmental protection coefficient needs to be improved.

[0038] The usage method of this embodiment is as follows: The other specific component structures of the aluminum single board coating device body, and the coating principle of the environmentally friendly and highly weather-resistant aluminum single board are prior arts. In addition, this component and technology have also been disclosed in the above prior art CN217963108U and are the same, so no further elaboration will be made here;

[0039] Before the aluminum veneer is sent into coating by the roller conveyor 100, the aluminum veneer will first enter the U-shaped support plate 1 on the leftmost side. When the recognition camera 8 recognizes the entry of the aluminum veneer, it transmits an opening signal to the controller 7. When the controller 7 receives the opening signal, it controls the exhaust fan 14 and the driving motor 5 to start automatically. When the driving motor 5 starts, it drives the roller brush 6 to rotate forward to sweep and remove dust from the top of the aluminum veneer, achieving the effect of automatically rotating and cleaning the aluminum veneer when it enters, so as to achieve the effect of automatically cleaning the aluminum veneer integrally before entering the coating, and avoiding the influence of more impurities on its top on the subsequent coating quality;

[0040] When the exhaust fan 14 starts, it provides a suction force inside the rectangular box 2. The rectangular box 2 successively sucks the swept dust and impurities through a plurality of horizontal pipes 901 and a plurality of dust suction pipes 9. The box-shaped stainless steel filter screen 10 filters the dust gas sucked into the dust suction pipe 9, achieving centralized collection of dust and impurities. By the method of integrally and automatically sucking, filtering and collecting the dust generated during sweeping during rotation, it can avoid the phenomenon that dust and impurities fall again to affect the environment and the aluminum veneer that enters later again, further improving the treatment effect and the on-site environmental protection effect;

[0041] With long-term use, when the bristles on the roller brush 6 are worn and cannot effectively contact the aluminum veneer, the operator can start the electric telescopic rod 3 forward to drive the rectangular box 2 to move downward. The rectangular box 2 drives the two vertical guide rods 16 to slide downward in the corresponding outer pipes 15 respectively. The rectangular box 2 drives the roller brush 6 to move up and down through the U-shaped rod 4. By using the method that the roller brush 6 can be adjusted downward, it is convenient to continue the stable cleaning work by lowering the outside bristles after wear, improving its service life and cleaning stability;

[0042] After use, when the collected dust and impurities and the box-shaped stainless steel filter screen 10 need to be removed and cleaned later, directly pull the U-shaped handle to the right. The U-shaped handle drives the iron box cover 12 to separate from the rectangular box 2 and the magnet block 13 to the right. The iron box cover 12 drives the box-shaped stainless steel filter screen 10 to move out to the right through the connecting rod. At this time, the impurities filtered and collected inside can be poured out and cleaned. Then the operator can clean the box-shaped stainless steel filter screen 10. After cleaning, insert the box-shaped stainless steel filter screen 10 and make the iron box cover 12 cover the right side of the rectangular box 2 again and adsorb and fix it with the magnet block 13, making it convenient to remove and clean the box-shaped stainless steel filter screen 10 quickly and conveniently after use.
