Road Painting Machine

Road painting machine is widely used for marking restrictive signs of different guidelines and warnings on highway, parking, square, runway and other flat road. Road marking equipment has played an important role in city planning and road construction, because of its advantages of high speed, high performance, innovative tech, proven quality.

Because the paint does not require compressed air atomization, it is called airless spray. Cold paint road marking machine uses high pressure equal flow type airless sprayer. This line marking machine is driven by Honda engine to form a high pressure for spraying. The spray gun uses rod lifting design, accurate and convenient spray width adjustment make the line evenly thick and uniform.This series of line marking machine for sale are suitable for road marking, runway routes, garage marking and so on.

Features:

  1. High efficiency:spraying efficiency is up to 200-500㎡/h, which is more 10 times than the drive roller.
  2. High quality: sprayed layer is smooth, dense, no brush marks, roll marks or particles.
  3. Long life for using: high-pressure airless spray enables the paint particles to penetrate into the voids of the road. So the paint film and road surface form a mechanical bite, enhance the paint adhesion, and prolong the service life.
  4. It is easy to paintcorners, voids and uneven brushing areas.
  5. Save paint: the coating utilization rate is high. And it is easy to obtain a thickness of 30um coating for airless spraying, which can save 20-30% of the coating.

Structure of Road Painting Machine:

Cold spray marking machine consists of frame, gasoline engine, main body of pump body, suction and gas valve, pressure regulator valve, high pressure hose, spray gun, suction mounting, and gun mounting, etc.

Vehicular Scribing Machine

Airless spray marking machine pressurizes the paint to 3000PSK 210Kg/cm by a high-pressure plunger pump, the high-pressure paint is delivered to the spray gun through high-pressure hose, and the pressure is released through the nozzle to form a spray, thereby forming a dense coating on the wall surface.

What Should We Do Before Line Marking Machine Working?

  1. The paint to be sprayed must be filtered through a 60-mesh screen;
  2. Install the high-pressure hose, spray gun, nozzle, suction tube and so on.
  3. Check the connectionof every part in the high pressure system.

Test Step Before Spraying:

Put a amount of water into the tank, and open the exhaust air valve with counterclockwise, start the motor, rotate the pressure regulator valve in clockwise. When the water is sucked into the suction pipe and flow out of the return pipe, close the exhaust air valve and rotate the pressure regulator valve in clockwise until air is drained. When the pressure gauge reaches about 1500psi, check back-flow and leakage of the return pipe and other connectors.

If these phenomenon exists, press “Pressure Relief Step” to relieve pressure first, then tighten the leaked part. If not, open the spray gun to perform the test and keep the pressure between 1000-1300psi.

Pressure Relief Procedure:

  1. Open pressure regulator valveand exhaust air valve in counterclockwise.
  2. Close the motor switch.

Note:

When opening the air exhaust valve, you should grasp the air exhaust valve hose firmly for avoiding falling off.

How to Maintain the Cold Paint Marking Machine?

  1. Sprayer should be cleaned immediately after finishing the spraying operation, which can remove any residual paint and prevent it becoming hard. It also need to change the paint into the corresponding solvent, operate the machine until all paint in the machine sprayed.
  2. It is necessary to clean the filter of the spray gun after using the road marking machine for a period of time. If the filter element is found to be damaged, the new filter element should be replaced.
  3. Spraying is not smooth during the spraying process, please check and clean the aspiration filter in time.
  4. Periodically check if the fasteners are loose, and the seals are leaking.
  5. Clean the oil inlet filterregularly, which can prevent foreign body plungers from causing abnormal wear of the plunger.
  6. Under normal conditions, it is necessary to check whether the hydraulic oil is clean and missing, after spraying for 400hours. If hydraulic oil is clean but missing, add it; or it is not clean, replace it. Replace the hydraulic oil, it is need to clean the oil chamber of the pump body with kerosene first, and then fill up the hydraulic oil.
