The automatic mortar spray machine is a special coating equipment using spraying technology. The principle is to control the airflow to instantly push the air distribution reversing device to reverse, so that the piston of the air motor can make stable and continuous reciprocating motion. The automatic mortar sprayer pressurizes the sucked paint, and transports the paint to the spray gun of the sprayer through a high-pressure hose, and the spray gun instantly atomizes the paint and releases it to the surface of the object to be coated. The spraying machine is mainly composed of a feeding device, a spray gun, and an atomization source.
The main working part of the automatic mortar spray machine is a double-acting pneumatic hydraulic booster pump, and the reversing mechanism is a special form of pilot fully air-controlled air distribution reversing device. After entering the compressed air, when the piston moves to the upper or lower end of the cylinder, the upper pilot valve or the lower pilot valve is actuated, and the air flow is controlled to instantly push the air distribution reversing device to reverse, so that the piston of the air motor makes stable and continuous reciprocating motion . Because the piston is rigidly connected with the plunger in the paint plunger pump, and the area of the piston is larger than that of the plunger. This pressurizes the sucked paint. The pressurized paint is transported to the airless spray gun through the high-pressure hose, and finally the hydraulic pressure is released at the airless nozzle, and sprayed on the surface of the object after instantaneous atomization to form a coating layer.
