The feed inlet 12 is arranged at the bottom of the coating box 1, and the air pump interface 11 is arranged at the top of the coating box 1, so that the coating is conveniently discharged.
When spraying, the variable air pump 4 rotates to enable air to enter the paint direction 1 through the air pump interface 11, then the paint in the paint box 1 enters the pressure box 3, and the paint is sequentially sprayed out through the discharge hole 34 and the spray gun 2 under the driving of air flow, meanwhile, the real-time pressure in the pressure box 3 is detected through the pressure sensor 5, and the controller controls the start and stop and the rotating speed of the variable air pump 4 according to the real-time pressure, so that the spraying flow of the spraying equipment is regulated in real time on line, the response speed is higher, meanwhile, the working pressure is ensured to be stable due to the real-time detection of the pressure, and the spraying is more uniform.
Further, the discharge port 33 is communicated with the spray gun 2 through a pilot sequence valve 6, and an overflow port of the pilot sequence valve 6 is communicated with the coating tank 1. When the pressure of the gas-liquid mixture in the pressure tank 3 reaches a preset value during normal spraying, the pilot sequence valve 6 can be opened to communicate the discharge port 34 with the spray gun 2, so that the paint enters the spray gun 2 from the discharge port 34 through the pilot sequence valve 6 to be sprayed, namely, the normal spraying can be performed only when the pressure meets the requirement, and the spraying quality is ensured. When the pressure of the gas-liquid mixture is too high, the overflow port of the pilot sequence valve 6 is opened, and part of the paint flows back to the paint box 1 through the overflow port, so that the pressure safety of the equipment is ensured.
In the spraying device provided by the embodiment of the invention, the pressure tank 3 is further provided with the first air tank connector 32 and the second air tank connector 33, the first air tank connector 32 and the second air tank connector 33 are communicated with the air tank 7 through the control valve, and the controller can control the communication state of the pressure tank 3 and the air tank 7 through the control valve.

The specific working mode is that when the paint spraying device is started, the controller controls the two-position three-way electromagnetic directional valve 8 to be in a first working position, gas in the gas storage tank 7 enters the pressure tank 3 through the first gas tank interface 32, and meanwhile, the variable air pump 4 accelerates to rotate, so that paint in the paint tank 1 enters the pressure tank 3 and is sprayed out through the spray gun 2. Meanwhile, the pressure sensor 5 monitors the pressure in the pressure box 3 in real time, and when the pressure reaches a preset value, the controller can send out instructions to control the variable air pump 4 to rotate at a constant speed.
When the spraying flow is required to be reduced in normal operation, the rotating speed of the variable air pump 4 is reduced, the two-position three-way electromagnetic directional valve 8 is controlled to be in the second working position, and the air in the air storage tank 7 enters the pressure tank 3 through the throttling part of the second one-way throttle valve 10, so that the air inflow is reduced, and the spraying flow is further reduced. When the spraying flow is required to be increased, the rotating speed of the variable air pump 4 is increased, the two-position three-way electromagnetic directional valve 8 is controlled to be in the first working position, and the air in the air storage tank 7 normally enters the pressure tank 3 through the one-way part of the first one-way throttle valve 9, so that the air inflow is increased, and the spraying flow is further increased. The preset pressure value is adjusted while the rotating speed is changed, and when the preset pressure is reached, the variable air pump 4 is kept at a constant speed, so that the spraying uniformity is ensured.
On the basis of the spraying equipment provided by the above embodiments, the discharge port 34 is arranged at the bottom of the pressure tank 3, the feed port 31 is arranged in the middle of the pressure tank 3, the first air tank interface 32 and the second air tank interface 33 are arranged at the top of the pressure tank 3, a certain amount of paint can still be reserved in the pressure tank 3 after the paint stops entering the pressure tank 3, and the paint is sprayed out through the gas drive in the air storage tank 7, so that the service time is correspondingly prolonged, and the continuous operation is convenient.
