[0014] After cleaning is completed, the piston rod of the opening and closing cylinder is retracted upward to the initial state, and the piston rod of the opening and closing cylinder drives the two L-shaped ear plates and the valve cover to rotate counterclockwise upward through the hinge rod. When the valve cover is opened, all the dot coating spray holes are opened, and the next dot coating and marking work cycle can be entered, realizing the timed automatic cleaning function.
