Powder Spray Coating Line With Suspension Conveyor Chains For Metal Coating Machinery

The seven integral part of the coating line mainly include:

pre-treatment equipment, powder coating systems, painting equipment, ovens, heat system, electric control system, suspension conveyor chains.

The multi-position spray before handling units commonly used surface treatment equipment, its original coating line is the use of mechanical erosion to complete the process of degreasing, phosphating, washing speed up chemical reactions.

Typical steel spray pre-treatment process: pre-degreasing, degreasing, washing, washing, surface conditioning, phosphating, washing, washing, pure water. Pre-treatment may also be used shot blasting machine, suitable for simple structure, severe corrosion steel, oil or less oil. And water pollution.

Powder coating cyclone filter recovery is more advanced and faster, change color powder recovery. A key part of the powder coating system suggested the use of imported products, powder room, electrical machinery lifts all parts localization.

Painting equipment
Such as spray painting room, curtain spray booth can be widely used in bicycle, car leaf spring, the surface coating of large loaders.

Curing Ovens
The oven is one of the important equipment in the coating production line, its temperature uniformity is an important indicator to ensure the quality of the coating. Oven heating: radiation, hot air circulation and radiation hot air circulation, according to the production program can be divided into single rooms and by type, equipment in the form of straight-through and bridge. Hot air circulation oven insulation, furnace temperature uniformity, less heat loss, has been tested and the furnace temperature difference is less than ± 3oC performance indicators can reach the advanced countries of similar products.
 

Heat source system
Hot air circulation is more common heating mode, which uses the principle of convection-conduction oven heated to the drying and curing of the workpiece. The heat source can be selected according to the user's specific situation: electricity, steam, gas or fuel. The heat source box Ovens: placed at the top, bottom and sides.

Electronic control system coating, coating line electrical control concentration and a separate control. Centralized control of the programmable logic controller (PLC) to control the host control program prepared by various processes for automatic control, data acquisition and monitoring alarm. Single row control is the most commonly used coating production line control mode, the various processes separate control, electronic control box (cabinet) is set near the equipment, low cost, intuitive operation and easy maintenance.

Suspension conveyor chains
Hanging conveyor conveyor systems, industrial assembly line, coating line product release type hanging lose applied to L = 10-14M storage shelves and shaped lights alloy steel pipe coating line. The lifting of the workpiece (Supports up to 500-600kg), smoothing out of the turnout, turnout based on the work order by the electrical control opening and closing, to meet the automatic transfer of the workpiece in the entire Polytechnic bit, dedicated hanging in the strong cold room, under parts within the region parallel product release cooling and located in the strong cold regions linked with the identification and traction alarm shutdown
