Since building boards are exposed to wind, sun, rain and corrosion for a long time, in order to extend the service life of building materials, their surfaces are sprayed during the processing of building boards. Generally, building boards are sprayed manually, with low spraying efficiency and poor spraying quality. Since the degree of automation is low during manual spraying of building boards, and there is a lack of pre-cleaning treatment, the surface spraying effect is poor, and the sprayed surface cannot be dried in time, resulting in low drying efficiency of the sprayed surface, which greatly reduces the surface processing efficiency of the entire building board. During the board transmission process, the position of the board cannot be adjusted, and the board may not be placed neatly.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the transmission adjustment mechanism, when conveying building boards, the transmission motor is started to drive the transmission roller to rotate, the board is placed on the transmission roller for transmission, and then the support plate is pushed to move by the electric push rod in the adjustment component, so that the push plate pushes the board to move, so that the board is attached to the inner side of the fixed guide plate, so that the board is neatly placed along the fixed guide plate, and building boards of different widths can be neatly placed and conveyed to move, which is convenient for subsequent cleaning, spraying and drying of the board surface;

[0017] 2. Through the surface cleaning mechanism, when the building board moves to the bottom of the dust box, the first cylinder is started to push the dust box downward, so that the guide pressure roller and the cleaning roller are pressed on the board surface, and then the cleaning motor and the vacuum cleaner are started, so that the cleaning roller cleans the dust on the board surface into the dust box, and the dust is sucked into the vacuum cleaner through the vacuum pipe.

[0018] 3. Through the precise spraying mechanism, when the cleaned building board moves to the bottom of the spraying rack, the second cylinder is started to push the adjustment box down so that the spraying rack is close to the surface of the board. Then, according to the width of the board, the adjustment structure inside the adjustment box is used to start the stepper motor to drive the transmission screw to rotate, so that the slider moves along the bottom of the adjustment box. Since one of the spraying racks is connected to the bottom of the slider, the distance between the two spraying racks can be adjusted so that the spraying rack just covers the surface of the board. Then, the booster pump is started to spray the paint in the paint box through the guide pipe from the spray nozzle, so that the surface of the board can be accurately sprayed to prevent incomplete spraying or waste of paint. Through the stirring component, the paint in the paint box can be stirred so that the paint is evenly mixed, which is conducive to improving the spraying effect.

[0019] 4. Through the high-efficiency drying mechanism, when the sprayed building board moves under the drying hood, the fan and heating pipe are started, so that the external air is discharged into the drying hood through the air inlet pipe, filter assembly, buffer box and spoiler in turn for heating, and the cold air introduced can be filtered, buffered and decelerated, so that the hot air discharged from the drying hood is gentle and stable, and then the surface of the sprayed board is dried by the heat of the heating pipe and the hot air discharged from the drying hood, so as to prevent the sprayed surface of the board from being rippled and blown due to the high wind speed, and effectively improve the drying effect and efficiency;

[0020] 5. The present invention can arrange building boards of different widths neatly and transport the boards by means of the transmission and adjustment mechanism. During the movement of the boards, the board surfaces can be cleaned and dusted, accurately sprayed and efficiently dried in turn, thereby improving the degree of automation of spraying on the board surfaces, and improving the spraying effect and work efficiency.
