and a microwave drying step, wherein a microwave generating device generates microwaves, and the microwaves are emitted to the surface of the workpiece from points and lines to carry out microwave drying.
When the workpiece paint spraying process is carried out, the workpiece can pass through the dust remover, the paint sprayer, the hot air dehumidification tunnel and the microwave dryer in sequence through the conveying line, and the dust removing step, the paint spraying step, the hot air dehumidification step and the microwave drying step are sequentially carried out.
In the dust removal step, the dust collector of dust shaker can remove dust and get rid of static to the work piece surface, the dust collector of dust shaker can choose for use for the cleaning roller and the static roller that the pin joint is in the dust shaker body, the cleaning roller cleans the work piece surface at the rotation in-process, and static can be got rid of to the static roller at the rotation in-process, the dust removal height of concrete dust shaker can be driven by a actuating mechanism and carry out automatic adjustment, namely first actuating mechanism can drive the cleaning roller, the up-and-down motion of static roller, according to the quick automatic adjustment of the thickness of work piece, and the dust collection efficiency is improved.
The paint is sprayed in the paint spraying step after dust removal, and the surface of the workpiece to be sprayed is clean, so that the condition that the paint surface is uneven due to dust can be avoided when the workpiece to be sprayed is sprayed with paint. When spraying paint, the height of the paint spraying gun and the surface of the workpiece is adjusted through the second driving mechanism, and the height is also adjusted according to the thickness of the workpiece, so that the operation is flexible.
After the step of spraying paint, can be through hot-blast dehumidification step, can blow at the blast apparatus in hot-blast tunnel, wind can evenly blow through the air outlet of even densely covered in the hot-blast tunnel, and no dead angle is to work piece progress air-blast drying, and is dry even and efficient. After the hot air dehumidification step, the surface moisture of the paint surface of the workpiece can be volatilized, and the primary air drying is carried out. In the microwave drying step, the microwave generated by the microwave generating device is emitted by points and lines, so that the water can be quickly, effectively and uniformly oscillated from inside to outside, and the drying process is accelerated.
Therefore, through the series of steps, the paint thinner on the surface of the workpiece is made into water, can be quickly and uniformly dried from the outside to the inside, volatilizes from the deep layer and dries, the paint drying efficiency is uniform, and the drying quality is good.
It should be noted that, the first driving mechanism and the second driving mechanism can be implemented by linear motors in the prior art, which is convenient for electric control.
