Conveyor Chains for Spraying Equipment are core transmission components in coating production lines (such as painting and powder spraying lines in industries like automotive, furniture, and hardware products). They are mainly responsible for conveying workpieces to be sprayed to different processes such as the spraying area, drying area, and curing area according to a predetermined trajectory and speed, ensuring the continuous and efficient progress of the spraying process. Their performance directly affects the spraying quality (such as coating uniformity), production efficiency, and equipment stability.
Material Selection:
- Core components (chain links, pins) commonly use high-strength alloy steel or stainless steel. Through heat treatment (such as quenching), their wear resistance and tensile strength are improved to adapt to the high-load operation of the spraying line.
- Brackets or fixtures in contact with workpieces may adopt surface-treated steel (such as galvanized or chrome-plated steel) or non-metallic materials (such as high-temperature resistant plastics) to avoid scratching the workpieces or interfering with coating adhesion.
Special Designs:
- Some chains need to have corrosion resistance (as spraying areas often have paint, solvents, or high-temperature gases). Therefore, stainless steel materials or surface-sprayed anti-corrosion coatings are used.
- Overhead Conveyor Chains are designed in a closed-loop track type. The chains run along preset tracks (such as I-beam guide rails) to realize the conveying of workpieces along complex trajectories such as uphill, downhill, and turning.
Typical Applications:
-
Automotive industry: Electrophoretic coating lines and topcoat spraying lines for vehicle bodies and components (overhead conveyor chains are mostly used to achieve 360° dead-angle-free spraying).
-
Furniture industry: Painting/powder spraying lines for wooden boards and metal furniture (plate-type conveyor chains are commonly used, combined with pallets to carry flat workpieces).
-
Hardware products: Mass spraying of small hardware parts (such as bolts and lamp accessories) (mesh belt-type chains may be adopted to realize the conveying of dense workpieces).
-
Building materials industry: Continuous spraying production lines for aluminum profiles and color steel plates (long-distance conveyor chains are required to adapt to the linear coating of large workpieces).
