The mortar spraying machine is much faster than the original manual brushing and roller coating. The choice is because the paint directly passes through the spray gun to the surface of the object to be painted, and does not need to be continuously brushed to the painter. It is more uniform. Moreover, the film thickness can be achieved at one time, which reduces the number of construction passes.
Because different models of high-pressure airless spraying machine have different pressure ratios and flow locations, plus the selection of various specifications of nozzles, they can be adapted to various types of coatings with different viscosities, so high-pressure airless spraying machine have a wide application , ships, machinery and equipment, boilers, automobiles, bridges, road signs and furniture are all automatically sprayed with an assembly line.
The so-called automatic coating line is the automatic blasting of steel plates or sections. After removing the oxide scale and rust layer on the steel surface, in order to prevent the steel plate from rusting again, pre-coat a layer of steel plate pretreatment workshop. The old formation and exclusion.
There are three types of mortar spraying machine lines: horizontal, vertical, and inclined spraying. Usually, the most horizontal spraying type is used. This type is composed of a high-pressure airless spraying machine, an automatic spray gun, a double chain of a moving gun motor, an air pipe moving by the spray gun, and a steel plate transmission line. The movement of the automatic spray gun is driven by a chain or a cylinder. When the steel plate is transported on the raceway, it is sprayed once by walking a certain distance (one spray width) by counting method. The time for spraying paint mist is controlled by the proximity switch, that is, when the nozzle leaves the steel plate, the stroke switch sends a signal to make the spray gun cut off the air source and immediately stop spraying.
The reciprocating motion of the spray gun is driven by a chain. Pin in movable chute. Fenzhou Ripple is fixed. The gun moves to the right when the pin is on the top and to the left when it is on the side.
The spray strokes of different steel plate widths are different, which means that the automatic spray gun sprays back and forth, and has a repainting width of 1/2. The smaller width steel plate is protected by the limit switch. When the automatic spray gun reaches the edge of the steel plate, the travel switch signal cuts off the air supply to the spray gun and immediately stops the spray. The automatic spray gun still moves forward. When approaching the steel plate back, the spray gun was opened and bite-coated. This is the case with two automatic spray guns.
