[0028] Working principle: When spraying a workpiece, first place the workpiece on the workbench 101, then start the rotating motor 104 to drive the nozzle 105 on the L-shaped plate 103 to rotate, and in the process of the nozzle 105 rotating, start the motor 5 to drive the nozzle 105 to swing up and down, so as to quickly complete the spraying operation of the workpiece by adjusting the angle of the nozzle 105;

[0029] In the process of the nozzle 105 swinging up and down, the feed pipe 106 will be bent. When the nozzle 105 swings too much, the arc block 604 on the mounting ring 603 will abut against the arc plate 602, so that under the guidance of the abutting force and the telescopic component, the arc plate 602 will be pushed to move closer to the fixed plate 601. In the process of the arc plate 602 moving closer to the fixed plate 601, the distance sensor 605 will detect that the distance of the arc plate 602 has changed. ization, thereby sending an electrical signal to the controller, and under the control of the controller, starting the air pump 902 to pressurize the feed pipe 106, thereby avoiding the flow of spray materials being blocked due to the bending of the feed pipe 106, so that the spray materials can flow out in time, and when the swing amplitude of the nozzle 105 is not large, the arc block 604 will not be against the arc plate 602. At this time, the air supply of the air pump 902 will be stopped, thereby avoiding the pipeline rupture or the spray material flow level due to excessive pressure in the feed pipe 106.
