Automatic Paint Line for Hopper
This powder coating line it is designed by COLO and exported in Europe in 2014 year!
Electrostatic Coating line usually consisting of seven main powder coating equipment include: Pre-treatment equipment, powder spray systems, spray gun, ovens for drying and curing, heat system, electric control system, suspension conveyor for loading and unloading, etc.
Process of powder coating line:
| 1. | Pre-treatment equipment |
| 2. | Powder coating booth |
| 3. | Electrostatic powder spray gun system |
| 4. | Powder coating oven |
| 5. | Heat system |
| 6. | Electronic control system |
| 7. | Hanging Chains system |
1. Pre-treatment equipment
Multi-position spray pre-treatment unit is commonly used in surface treatment equipment, the principle is the use of mechanical erosion accelerate chemical reactions to complete degreasing, phosphating, washing and other processes. Typical process steel spray pre-treatment are: Pre-degreasing, degreasing, washing, washing, table transfer, phosphating, washing, washing, pure water. Pre-treatment can be applied to shot blasting machine for simple structure, severe corrosion, oil, oil-less steel. And no water pollution.
2. Powder coating booth -- there are two types --cylone booth or filter booth
In the Powder coating, the muti- small cyclone plus the filter recovery is more advanced, color changing faster powder recovery
3. Electrostatic powder spray gun system ---colo serise Electrostatic powder coating spray gun, high stability, high extraction rate, to ensure high quality finishing.
4. Powder coating oven ----Drying oven is one of the important equipment in the coating production lines, its temperature uniformity is an important indicator of the quality assurance coating. Heating ovens are: Radiation, radiation hot air circulation and hot air circulation, etc., according to the production program can be divided by type, such as a single room and equipment in the form of straight-through and bridge. Hot air circulation oven good insulation, furnace temperature uniformity, less heat loss, has been tested, the furnace temperature is less than ± 3degree.
5. Heat system
Hot air circulation is currently the more common heating method, which uses the principle of conduction convection oven is heated to dry and cure the workpiece. Heat according to the specific circumstances of the user's choice: Electricity, steam, natural gas, coal or fuel oil. Heat oven box under the circumstances, may be: At the top, bottom and sides. Production of heat circulating blower case of a special high-temperature fan, you have a long life, low energy consumption, low noise, small size and so on.
6. Electronic control system
Painting, coating line and a separate electrical control has focus control. Centralized control can adopt programmable controller (PLC) to control the host, prepared in accordance with the control program for automatic control of various processes, data collection and monitoring alarms. Coating production line control is the single most common control, each single process control, electrical control box (cabinet) is set in the vicinity of the device, low cost, intuitive operation, easy maintenance
7. Hanging Chains system
Overhead conveyors industrial assembly line, coating line conveyor systems, lifting the workpiece on a dedicated rack (Supports up to 500-600KG), to meet the automatic transmission in the entire workpiece Polytechnic bit
