The non-curing spraying machine is a special coating equipment that uses spraying technology. The principle of the non-curing spraying machine is to control the air flow to instantly push the gas distribution reversing device, so that the piston of the pneumatic motor makes stable and continuous reciprocating motion.
The inhaled paint is pressurized and delivered to the painter's spray gun through a high-pressure hose, which instantly atomizes the paint and then releases it onto the surface of the object being painted. The non-curing spray machine mainly consists of a feeding device, a spray gun and an atomization source. It is suitable for leather handbags, gift packaging, furniture, footwear, automobile manufacturing and other industries.
What is the structure of a non-curing sprayer? Let’s take a brief look at it together.
The non-curing spray machine mainly consists of a feeding device, a spray gun and an atomization source. The atomization source varies depending on the type of sprayer: the atomization source of the air sprayer consists of an air compressor, air pipe, air oil-water separator and air storage tank; the atomization source of the airless injector consists of a power source and a high-pressure pump; electrostatic The atomization source of the sprayer consists of a high-frequency and high-voltage electrostatic generator.
Non-curing sprayers include spraying and drying. The working mechanism includes a spray chamber equipped with nozzles, a leather conveyor belt, a drying system and a cleaning mechanism. After 2012, rotary multi-nozzle closed spray chambers are mostly used, and the nozzles are opened and closed controlled by ultrasonic waves or computers to achieve skinless spraying, save finishing agents, reduce pollution, and achieve high finishing efficiency. The sprayed leather is sent to the drying area by a conveyor belt and collected from the other end after drying.
Non-curing spraying machine is a special spraying equipment using 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 to form high-pressure paint. It forms an atomized airflow through the nozzle and mouth, which acts on the surface of the object (wall or wood surface). It is similar to gas spraying. The paint surface is even and grain-free. Because it is isolated from the air, the paint surface dries and is clean. Airless spraying can be used for the construction of high-viscosity coatings with clear edges, and can even be used for some spraying projects with boundary requirements. According to the type of machinery, it can also be divided into pneumatic airless sprayers, electric airless sprayers and internal combustion airless sprayers.
What is the maintenance method for non-curing sprayers? Let’s take a brief look at it together.
1. Maintenance of spray booth in spray line. If the air supply system of the spray cabinet is blocked or there is too much dust, the air filter cotton should be replaced, and the oil filter system behind the spray cabinet should be opened for cleaning in about three days. At the same time, it is also necessary to clean the oil on the conveyor chain from time to time and add butter.
2. Maintenance of oil supply system. When the sprayer needs to be stopped after use, open the paint return valve to allow all the paint to flow back into the ink tank, take out the ink tank, pour the cleaning solvent into the mixing barrel, and start the oil pump. In addition, open the return valve and spray gun to circulate the cleaning solvent in the oil pipe and clean the spray gun and oil pump. Due to the high precision of the pump and spray gun, do not disassemble them at will during cleaning to avoid damage.
3. After one week or 50 hours of operation, check the sealing condition of the pump body and cylinder of the mortar combination machine, the tightness of the transmission belt, the firmness and tightness of the pipe joints, clean the appearance of the pump, and apply thin oil to prevent Dirt sticks.
4. Major components such as clutches, return unloading valves, reducers, and air compressors should be inspected regularly according to their usage requirements. If there is any wear and damage, it should be adjusted and replaced in time.
5. Before refueling the mortar mixer and mortar binding machine, the dirt on the oil filling port and oil hole should be wiped clean.
