[0031] It should be understood that the original reason of the automatic spraying machine and the paint mist recovery device is composed of the spray gun 52, the pneumatic system, the motion system and the control system. Among them, the pneumatic system is mainly responsible for sending the high-pressure spraying liquid into the spray gun 52.

[0032] The specific operation process is as follows:

[0033] I. The paint in the pressure tank is pressed out by compressed air.

[0034] II. The liquid pressure is raised to the high pressure required by the spraying machine through the pressure regulating valve.

[0035] III. After the liquid passes through the flow regulator and the filter, it enters the spraying machine, and the spraying process is completed through the nozzle and the atomizer.

[0036] IV. The air pressure is sent into the spraying machine by the pneumatic compressor, the liquid is thrown out of the nozzle, and the atomization state is formed to uniformly spray on the workpiece surface.

[0037] In an embodiment of the utility model, as shown in Figures 1-4 The dust suction assembly 6 includes a dust suction pipe 61 and a negative pressure generator 62, wherein the negative pressure generator 62 is installed at the top of the dust suction pipe 61, a connecting hose is arranged between the negative pressure generator 62 and the spray protection cover 4, and the negative pressure generator 62 and the spray protection cover 4 are connected through the connecting hose.

[0041] The automatic spraying machine and the paint mist recovery device are mainly used in industrial automation production, and the main functions are as follows: first, the sensor receives a high-level signal to the single-chip microcomputer, which analyzes and calculates using chip control technology, and gives a 3s control signal to the paint spraying electromagnetic valve. The electromagnetic valve is opened, and the paint spraying gun starts to work. At the same time, the negative pressure generator is also opened, which is equivalent to spraying paint and extracting paint mist at the same time.
