Selection of spraying robot spray gun
The spray gun is an important part of the spraying robot. If it is used improperly in the spraying operation, it will affect the spraying effect of the product. Therefore, the choice of the spray gun of the spraying robot is very important. When choosing a spraying robot spray gun, factors such as the size of the sprayed object, the type of paint, and the quality registration standard for spraying should be considered. Let's share with Songle Robot below.

If the objects to be painted by the spraying robot are large, a spray gun with a larger caliber should be used, so that the paint output is large and the speed is fast. When the spraying quality requirements are high, a paint spray gun with good spray nozzle atomization should be selected. On the contrary, if the objects are large and the quality requirements are not high, choosing a spray gun with good atomization will affect the efficiency.
Spraying robot spray gun
If the spraying robot uses a small amount of paint when spraying, the area of the sprayed object is small, and there are many types of colors, the use of a large spray gun will cause waste and cannot improve the quality. At this time, a gravity spray gun should be used because the spray gun has a small paint capacity. It is convenient to change the color and save the thinner when cleaning the paint pot. The larger the caliber of the spray gun, the greater the air pressure required, the more paint sprayed, and the higher the consistency of the paint.
The caliber of the spraying robot spray gun and the air hole of the air cap of the spray gun nozzle are matched with each other. The air cap is divided into porous type and less-hole type. The porous type air cap has large air consumption, good atomization performance and good coating film quality. ；
The small-hole type air cap has a small amount of air, but has a poor atomization ability, and is suitable for objects with low requirements for spraying quality. The degree of atomization of the sprayed coating has a great relationship with the size of the spray gun's caliber, the viscosity of the coating, the amount of air exhaust from the air outlet, and the angle of the arrangement.
