Conghe Mechanical Reversing Spray Machine

Conghe Mechanical Reversing Spray Machineworking principle

The main working part of the spraying machine is a double acting pneumatic hydraulic booster pump, and the reversing mechanism is a special form of pilot controlled fully pneumatic air distribution reversing device. After entering the compressed air, when the piston moves to the upper or lower end of the cylinder, the upper or lower pilot valve is activated to control the airflow and instantly push the valve reversing device to change direction, thereby enabling the piston of the pneumatic motor to perform stable and continuous reciprocating motion. Due to the rigid connection between the piston and the plunger in the paint plunger pump, and the larger area of the piston compared to the plunger. Therefore, the inhaled paint is pressurized. The pressurized coating is transported to the airless spray gun through a high-pressure hose, and then the hydraulic pressure is released at the airless nozzle. After instantaneous atomization, it is sprayed onto the surface of the coated material to form a coating layer

structural composition

The spraying machine is mainly composed of a feeding device, a spray gun, and an atomization source. The source of atomization varies depending on different types and spraying machines: the atomization source of an air spraying machine consists of an air compressor, a gas pipeline, an air oil-water separator, and a gas storage tank; The atomization source of the airless sprayer is composed of a power source and a high-pressure pump; The atomization source of the electrostatic spraying machine is composed of a high-frequency and high-voltage electrostatic generator.

It consists of two parts: spraying and drying. The working mechanism includes a spray chamber equipped with nozzles, a leather conveyor belt, a drying system, and a cleaning mechanism. Since 2012, rotary multi nozzle closed spray chambers have been widely used, with nozzles controlled by ultrasound or computer for opening and closing, achieving leather spraying and no spraying without leather; Save coating agents, reduce pollution, and achieve high coating efficiency. The sprayed leather is transported by a conveyor belt to the drying area and collected from the other end after drying.

Spray coating machine is a spraying equipment that uses high-pressure airless spraying technology.

High pressure airless spraying, also known as airless spraying, uses a high-pressure plunger pump to directly pressurize the paint, forming high-pressure paint that is sprayed onto the surface of the object (wall or wooden surface) to form an atomized airflow. Compared to air spraying, the paint surface is uniform and has no graininess. Due to its isolation from air, the paint is dry and clean. Airless spraying can be used for the construction of high viscosity paints, with clear edges, and can even be used for some spraying projects with boundary requirements. Depending on the type of machinery, it can also be divided into various types such as pneumatic airless spraying machines, electric airless spraying machines, internal combustion airless spraying machines, etc.
