Full Automatic Powder Coating Production Line
Production Description:
The design of the automatic spraying line reduces a lot of labor. It mixes the powder with air in the powder feeder and sends it to the powder spray gun.
The high voltage generated by the high-voltage electrostatic generator is connected to the inside or front end of the powder spray gun.
The inside or outlet of the powder spray gun is charged, and under the combined action of air force and electrostatic force, the powder particles are sprayed on the workpiece to be coated in a directional direction.
Safety and environmental protection, high output, high efficiency, uniform coating.

Pre-treament:
Pretreatment equipment is widely used in the household appliance spraying industry (air conditioner, refrigerator, washing machine, etc.), mainly to effectively clean the oil stain generated during the processing of the product shell, form a protective film on the product surface, and improve the adhesion of the workpiece after powder spraying in the subsequent process. Ensure that the powder coating of the product is not easy to fall off and rust.
Automatic powder spraying room:
The powder is mixed with air in the powder feeder and then sent to the powder gun. The high voltage generated by the high voltage electrostatic generator is connected to the interior or front end of the powder gun. The powder is charged in the interior or outlet of the powder gun. Under the joint action of pneumatic force and electrostatic force, the powder particles are directionally sprayed on the workpiece to be coated. It can also be adsorbed to the back of the workpiece. When the powder attached to the workpiece exceeds a certain thickness, electrostatic repulsion occurs, and the subsequent powder is not easy to be adsorbed to the workpiece surface, so that the workpiece surface reaches a uniform film thickness.
Part of the powder is adsorbed in the cyclone collector under the action of the wind force, and the other part of the powder intermittently pulses the filter element under the action of the secondary filter element pulse controller and solenoid valve to vibrate the powder adsorbed on the surface of the filter element to the powder feeder at the bottom of the chamber for easy cleaning. The equipment is equipped with an automatic recovery system to ensure the normal circulation of powder, reduce powder consumption and save powder.
Ovens are divided into air heated ovens and electric heated ovens.
Gas heated ovens.
1. it has penetration and can be heated inside and outside at the same time to quickly achieve the purpose of drying.
2. no heat medium transfer is required, and the thermal efficiency is good.
3. it can also be locally heated to save energy.
4. the design breaks through the idea of traditional paint baking room, reduces the pipeline and heating mechanical system, makes the space combination, installation and maintenance simple and easy, greatly reduces the hidden trouble, avoids the disadvantages of huge energy consumption of ordinary electric paint baking room, and saves costs.
5. the heating process is environmentally friendly, free of pollution, electromagnetic radiation, clean, noise and secondary pollution.6. easy temperature control, rapid temperature rise and high safety.
Electric heated ovens.
1. Hot air circulates in the oven (generally can be heated directly with hot air), which has high thermal efficiency and saves energy;
2. Using natural gas as energy, the energy cost can be reduced by 40-50% compared with using power heating;
3. With forced ventilation, the oven is equipped with an air duct to dry the materials evenly;
4. The oven runs smoothly. Automatic temperature control, easy installation and maintenance;
5.It has a wide range of applications and can dry various materials. It is an ideal universal drying equipment.
We have a complete set of powder coating line.
Spray booth (recovered powder) - reciprocating machine - powder spraying machine - oven.
