4 key equipment components needed for a small painting line
Paint spraying is a widely used painting method for industrial production and personal DIY. As an independent painting line, a small painting line consists of several key equipments, each of which is responsible for different tasks in the painting process.
In this article, we will introduce the key equipment of the small painting line and its role.
I. Painting interval
The painting interval is the core part of the small painting line and one of the most important equipment in the painting process. The main role of the paint interval is to provide a painting site for the object and to control the pressure, flow and nozzle angle of the paint spray. The painting interval usually includes the following components:
1. Paint spray cabinet:
paint spray cabinet is an airtight container, usually used for applying liquid paint. After the paint is sprayed in the spray cabinet, a film is formed inside the spray cabinet and the film is transferred to the surface of the object by gas flow.
2. Spray gun:
A spray gun is a tool used to paint an object. It usually consists of nozzle, paint tube and gun trigger. The gun regulates the spraying volume and spraying direction of the paint by controlling the pressure and angle of the nozzle.
3. Compressed Air System:
A compressed air system is a device used to generate high pressure air to drive the paint from the spray gun. Compressed air system usually consists of air compressor, dryer and filter, these devices can remove the moisture and impurities from the paint to avoid problems during the painting process.
II. Purification System
Purification system is another key equipment of small painting line, which is used to remove exhaust gas and waste water generated during the painting process and to ensure clean air in the painting interval. The purification system usually includes the following components:
1. Exhaust gas purifier:
The exhaust gas purifier is a device used to remove the exhaust gas generated during the painting process. It can filter out the harmful substances in the exhaust gas and make the exhaust gas emission meet the environmental protection standard.
2. Clean room:
Clean room is a closed space for filtering air and ensuring clean air in the painting interval. The clean room usually adopts high efficiency filtration technology to filter out dust and microorganisms in the air to ensure that there is no impurity pollution in the painting process.
3. Clean water system:
Clean water system is the equipment used to remove the wastewater produced during the painting process. It can remove the harmful substances in the waste water and make the waste water reach the environmental protection standard.
III. Drying system
Drying system is another important equipment of small painting line, which is used to accelerate the drying and curing of paint. The drying system usually includes the following components:
The oven is the equipment used to heat the painted object. Ovens usually use electricity or gas as the energy source, and the painted object is placed inside the oven for heating to make the paint dry and cure quickly.
2. Hot air blower:
A hot air blower is a device that generates high temperature airflow and is used to transfer hot air to the drying chamber for heating. The hot blower usually uses electricity or gas as the energy source to transfer the hot air into the oven for heating.
3. Cooling System:
The cooling system is the equipment used to cool the painted object. The cooling system usually adopts fan and air filter to transfer the cold air to the oven for cooling, so that the paint can be cured quickly.
IV. Automation control system
Automation control system is another important equipment of small painting line, which is used to control each equipment in the painting process and ensure the painting quality and production efficiency. The automation control system usually includes the following components:
1. PLC controller:
PLC controller is an intelligent control system used to control each equipment in the painting process. It detects the system status through preset programs and sensors to achieve automatic control and regulation of the painting process.
2. Touch screen:
The touch screen is a human-machine interface used to operate the PLC controller. It can intuitively display various parameters in the painting process and operate and set through the touch screen.
The sensor is a device used to detect various parameters in the painting process. It can detect parameters such as paint flow, temperature, pressure and humidity, and feed these parameters back to the PLC controller for automatic adjustment.
To sum up, small painting line consists of several key equipments, including painting system, filtration system, drying system and automatic control system.
- The painting system includes spray guns, paint sprayers, conveyor belts and paint recycling systems for painting and recycling painted objects.
- The filtration system includes air filters and clean water systems to filter out dust and microorganisms from the air and remove harmful substances from the waste water.
- The drying system includes ovens, hot fans and cooling systems for accelerating the drying and curing of the paint.
- The automation control system includes PLC controller, touch screen and sensors to control each equipment in the painting process and to ensure the quality of painting and productivity.
In addition to the key equipment and elements mentioned above, the configuration and optimization of a small painting line needs to be flexibly adjusted to the specific situation. In practical applications, we also need to consider factors such as the size, shape, material and coating requirements of the painted object in order to select the appropriate painting method and equipment. At the same time, we also need to pay attention to issues such as safe production and environmental protection, and take the necessary measures and technical means to ensure the safety of the production process and the hygiene of the environment.
In conclusion, the construction and optimization of small painting lines requires us to fully understand their key equipment and elements in order to better master their painting technology and operation methods, improve production efficiency and painting quality, and provide better services and products to our customers.
