When the workpiece is sprayed, the multiple workpieces on one side of the cylindrical shell 2 are sprayed by the spraying mechanism 4. After the workpiece spraying is completed, the drive motor 12 is started to drive the cylindrical shell 2 to rotate, so that the workpiece sprayed on the side of the spraying mechanism 4 moves to the side of the drying mechanism 5, and the workpiece installed on the side of the drying mechanism 5 moves to the side of the spraying mechanism 4. When the spraying mechanism 4 sprays the moved workpiece, the drying mechanism 5 can dry the workpiece that has been sprayed and moved.
