As shown in Figure 1, the operation panel of the control cabinet 4 is designed as two buttons, three indicator lights, and the two buttons are respectively a start-stop button and an emergency stop button. , press the emergency stop button to cut off the power to prevent accidents. The three indicator lights are red, green, and yellow. The red light indicates normal power-on status, the green light indicates normal operation of the device, and the yellow light indicates that the device has failed.

The turbine type proximity switch 1 83 and the turbine type proximity switch 2 84 are fixedly installed on the two side walls of the spray booth 8 through the connecting flange, and they are placed outside the starting position of spraying. When the proximity switch 1 83 senses the steel door processing 6, the detected signal is transmitted to the PLC in the control cabinet 4, after a certain delay processing, the operation of the whole equipment is started, the front spray gun 16 is sprayed from top to bottom, and the spray gun 95 of the back spray equipment is sprayed from bottom to bottom. And the upper spraying, and at the same time the front side spraying equipment 1 and the back side spraying equipment 9 follow the steel door synchronous transmission. When the proximity switch 2 84 senses the steel door processing part 6, it receives the delayed pause response signal of the proximity switch, which is passed to the PLC in the control cabinet 4, the spray gun stops spraying, the equipment starts to reset automatically, returns to the initial position, and waits. The arrival of the next workpiece, such reciprocating processing operations, where the proximity switch one and the proximity switch two are turbo-type, are existing mature products, and its structure and principle are all prior art. Proximity switch one, two and The electrical connection relationship between the control cabinets is also a prior art, and will not be repeated here.
