Automatic paint spraying machine will gradually replace the rapid development of high-tech spray booth and spray booth. Everything is gradually entering full mechanized production. CNC engraving machine is fully automated for wood door engraving, automatic painting machine for wooden door painting, etc. More and more manual The job is about to be replaced by this new CNC machine. In particular, the advent of automatic paint sprayers will replace the original manual spray paint faster. Because paint is more and more aware of the poisoning of the human body, it is inevitable that the high-impact painting work is mechanized.
Why is the automatic paint spray machine replacing the original manual spray process? First of all, we must first understand the characteristics of the manual spraying process. Manual spraying is mainly divided into direct spraying and spray booth spraying.
The spray booth, as its name implies, paints the paint spray object in a room and is now called the paint booth. The traditional painting is to spray paint on the open-air nozzles (cars, furniture, etc.), but this way the paint quality will be reduced for large appliances. For example, the dust in the air will be mixed in the paint during the painting process, thus reducing Paint quality; waste of paint with uncertainty, and the paint area will be very dirty; for the staff, it will be dirty on the one hand, and a large amount of paint mist will be harmful to the body on the other hand. Later, people wanted to set the spray paint within a certain range, and the earliest spray booth spray booth was produced. The spray booth in China was first produced in the Chengdu area in the 1990s.
First, the classification:
1), divided into three categories according to the direction of airflow.
Cross-flow spray booth:
Airflow flows from one end of the room to the other. This type of machine is low in cost and easy to install. The disadvantage is that the mist moves along the side of the body, and the mist cannot be removed from the operator's face, and the working environment is not satisfactory.
Side undershoot spray booth:
The air enters the spray booth through the filter unit of the ceiling and is discharged from the side wall of the room. This is a mid-range price spray booth. Since the mist is away from the body itself and the mist can be removed from the operator's surroundings, the paint effect and working environment are ideal.
2), classified by heating:
Can be divided into diesel spray booth, electric heating spray booth, steam heating spray booth, infrared paint booth, waste engine paint booth and so on.
3), classified by paint mist treatment:
Can be divided into dry spray booth and wet spray booth (water treatment) two categories.
The three key points of the exhaust paint booth are:
1. The key to the work of ventilation and ventilation spray booths.
2. Filter and filter small particles in the air.
3. Exhaust waste air discharge and new air intake.
Wind (outdoor air) - spray paint door filter cloth - spray booth - use spray paint equipment to spray paint - exhaust fan (paint mist generated by discharge) The weakness of this spray booth still exists:
1. The filter cloth is easily scratched and the dust is easy to enter.
2. Easy to enter the outdoor unclean air.
3. Not environmentally friendly, waste paint.
4. Need to clean frequently, regularly remove the dirt on the filter cloth.
