A driving mechanism for driving the turntable 10 to rotate is provided on the inner wall of one side of the frame 1. When in use, the valve body 8 is sleeved on the outer side of the circumference of the plug column 11 and is assisted by the rubber sleeve 12 to fix it. The conveyor belt 5 is started, and the fixed disk 7 will pass through the paint spraying mechanism 2 and the drying mechanism 3 in turn, so as to spray paint the valve body 8 on the conveyor belt 5. After the painting operation is completed, a drying operation is performed to solidify the paint on the outer surface of the valve, so that the painting operation can be carried out uninterruptedly. At the same time, there is no need to wait for the paint to dry, thereby improving the processing efficiency of the equipment.

[0021] Among them, the limiting mechanism includes at least one sliding hole 13, which is opened at the bottom of the turntable 10, and a slider 15 is slidably connected in the sliding hole 13. A spring 14 is fixed to the top of the slider 15 by a bolt, and the other end of the spring 14 is fixed to the sliding hole 13.

[0023] The drying mechanism 3 includes a second fixing frame 301, which is fixed to the top of the frame body 1 by bolts. The inner walls on both sides of the second fixing frame 301 are rotatably connected to two hot air blowers 306.
