The inside of the automatic spray gun has a pneumatic piston mechanism with a stainless steel needle above the piston and a set of high tension springs behind the piston. When the compressed air stops supplying, the spring pushes the piston and the needle forward. When the needle and the nozzle are closely matched with high precision to block the passage of the liquid, when the compressed air starts to be supplied, the pressure of the compressed air pushes the piston open, so that a gap is formed between the needle and the nozzle to allow the liquid to be ejected. The liquid after the ejection is then brought into contact with the atomizing air to produce an atomizing effect.

Spray booth seal
In order to make the air in the spray booth clean and dust-free, the doors and windows of the spray booth should be equipped with air purification and filtering devices. The 200-mesh silk cloth is usually installed on the doors and windows, so that the air entering the spray booth is filtered and dusted to achieve purification. purpose. In front of the workbench is a water curtain machine and an exhaust fan, which can make the flying paint mist generated during the spraying operation be discharged out of the room by the exhaust fan, keeping the indoor air fresh, which is beneficial to the health of the operator and prevents the flying paint. The mist splashes on the surface of the coated object after spraying, ensuring that the surface to be coated is smooth and smooth.
