8. A revolving body workpiece spraying equipment according to claim 7, further comprising an adjusting mechanism for adjusting the relative distance between the first endless conveyor belt and the second endless conveyor belt, wherein the adjusting mechanism comprises an adjusting rod provided with reverse threads connected to the first endless conveyor belt and the second endless conveyor belt, respectively, and an adjusting driving device for driving the adjusting rod to rotate to adjust the relative distance between the first endless conveyor belt and the second endless conveyor belt.
9. The rotary workpiece spraying device of claim 6, further comprising an air cleaning device in communication with the enclosure.
10. The hardware container spraying method of the revolving body workpiece spraying equipment applied to any one of claims 1 to 9 is characterized by comprising the following steps:
conveying the hardware container on a conveying surface of a conveying mechanism provided with more than two workpiece attachers;
the workpiece sensing element positioned at the last detects the workpiece, and the movable material blocking part positioned at the last extends to the conveying surface to block the workpiece so that the workpiece is stopped above the workpiece attachment device at the position;
the workpiece is detected by the previous workpiece sensing element, and when the workpiece is detected by the next workpiece sensing element, the corresponding movable material blocking element extends to the conveying surface to block the workpiece at the position, so that the workpiece is stopped above the workpiece attachment device at the position;
the centering clamping mechanism of the centering device is used for centering and positioning the workpieces above the workpiece attacher;
the lifting rotating mechanism lifts the corresponding workpiece attachment device to enable the workpiece attachment device to adsorb and lift the workpiece;
the cover body driving device drives the first sub cover and the second sub cover to be relatively jointed;
the lifting rotating mechanism drives the workpiece attachment device to drive the workpiece to rotate;
a mechanical arm of the spraying mechanism drives the spraying device to move along the direction of one bus of the workpiece on the workpiece attachment device for spraying;
after the spraying is finished, the cover body driving device drives the first sub cover and the second sub cover to be relatively separated, and the lifting rotating mechanism descends to enable the workpiece on the workpiece attachment device to fall onto the conveying surface of the conveying mechanism.
