Coating line works on the assembly line coating line is currently more popular in the market, a product of the seven components of painting lines include: pre-treatment equipment, powder coating systems, painting equipment, ovens, heat system, electric control systems, suspension conveyor and so on. Applicable to the surface of the painting, spray, used for single or small quantities of the workpiece painting, with overhead conveyors, electric rail cars, ground conveyor transport machinery to form transport operations. 1, 2 pre-treatment equipment folding, folding dusting powder coating systems in small cyclone + filter recovery is more advanced, color changing faster powder recovery. The key part of the dusting system suggested the use of imported products, powder room, electro-mechanical lifts and other parts are all domestic. 3, spray paint spraying equipment folding, using a Youlin spray booth, spray booth curtain, widely used in surface coating bicycle, automotive leaf spring, large loaders. 4, oven folding oven is one of the important equipment coating production lines, its temperature uniformity is an important indicator to ensure the quality of the coating. Heating ovens are: radiation, hot air circulation and radiation + hot air circulation, according to the production program can be divided into single rooms, and by type, etc., equipment in the form of straight-through and bridge. Kat billion special company produces hot air circulation oven good insulation, furnace temperature uniformity, less heat loss, has been tested in the furnace temperature is less than ± 3oC, achieve performance of advanced countries of similar products. 5, the heat source system is currently the hot air circulation fold more common heating method, which uses the principle of convection conduction oven heated to dry and cure the workpiece. Heat depending on the circumstances the user's choice: electricity, steam, gas or oil and so on. Heat oven box can be under the circumstances: on the top, bottom and sides. The company produces heat circulating blower fan for special high temperature, it has a long life, low energy consumption, low noise, small size and so on. 6, the electronic control system collapsed painting, painting lines and separate electrical control centralized control. Centralized control can programmable logic controller (PLC) to control the host computer, according to the control programming for automatic control of the various processes, data collection and monitoring alarms. Separate control is the most commonly used coating production line control mode, each separate process control, electrical control box (cabinet) is set in the vicinity of the device, low cost, intuitive operation and easy maintenance. 7, hanging conveyor folding machine is a conveyor system hanging lose industrial assembly line, coating line, the company designed and manufactured product release type suspension transport machine used L = 10-14M of storage shelves and street lamps shaped steel pipe coating line. Lifting a dedicated piece hanging on (load up 500-600KG), smoothing out the turnout, turnout based on the work instruction to open and close the electrical control, automatic transmission in the entire workpiece meet Polytechnic position, strong cold room, under the inner region parallel plot-cooled and strong cold region linked to identify and set alarm stop towing devices. The plot-type suspension transport aircraft, with low cost (about 1/3 of the domestic like product), major, space-saving advantages. Engineering process layout editing a folded, spray line of this paragraph: The conveyor chain - spray - drying (10min, 180 ℃ -220 ℃) ??- Cooling - the lower part 2, paint line: the conveyor chain - electrostatic dust - Primer - leveling - finish - leveling - drying (30min, 80 ℃) - Cooling - pieces of engineering characteristics of the application under this section folding editor coating line equipment for surface paint, spray, used for single or small quantities of the workpiece painting, with overhead conveyors, electric rail cars, ground conveyor transport machinery to form transport operations.
