The spraying robot head is equipped with an atomizer, which can complete the painting work evenly and stably. In the actual production process, the atomizer must be cleaned frequently, and a cleaning bucket is required during the atomizer cleaning process.

[0003] The Chinese patent with the authorization publication number CN108323161B discloses an improved cleaner for a paint spray gun used on an assembly line, including a container having an inlet, an outlet and a port for receiving an atomizer of the spray gun. An impeller is rotatably mounted in the container and is in fluid communication with the inlet. The impeller has an offset cleaning nozzle for spraying a cleaning spray toward the port and a rotating nozzle for spraying a rotating spray to achieve rotation of the impeller. The impeller also has an independently controlled central nozzle cleaning nozzle. The cleaner has an air wiper for removing excess solvent from the atomizer of the spray gun when the atomizer of the spray gun leaves the cleaner after a cleaning cycle. The cleaner includes a spiral flushing member and a solvent removal assembly for cleaning the inner wall of the container. Air and solvent separation accessories provide improved solvent discharge efficiency.

[0027] Working principle: When using the gas-liquid mixing structure of the cleaning bucket, firstly, gas and liquid are introduced through the gas one-way valve 7 and the liquid one-way valve 8 respectively, and compressed air is introduced into the rotary drive valve 4 at the same time. The compressed air enters the connecting pile 11 through the air inlet pipe 5. When the air pressure of the air source is added to the pneumatic components of the pneumatic rotary joint, the pneumatic components will generate thrust and transmit the thrust to the internal spiral mechanism. The spiral mechanism converts the thrust into a rotational torque through the design of the spiral line, thereby realizing the rotation function. The bearing can support the rotating parts, reduce the friction resistance, make the rotation more stable, and at the same time withstand a large load, ensuring the reliability of the rotary drive valve 4, so as to drive The rotating disc 2 and the spray assembly 3 are rotated to carry out the cleaning work.

This is the working principle of the gas-liquid mixing structure of the cleaning barrel.
