[0002] Metal fasteners refer to a general term for a class of metal mechanical parts used to fasten two or more parts or components into a whole. Their core function is to provide detachable or non-detachable mechanical connections to transmit force, motion, or seal. To improve their corrosion and rust resistance, metal fasteners undergo treatments such as hot-dip galvanizing. After treatment, the fasteners come out of the high-temperature plating or cleaning solution with a large amount of liquid adhering to their surface. The cooling process is also a process of rapid drying and coating setting. Therefore, a rapid cooling device for surface treatment of metal fasteners is needed.

[0003] Traditional cooling devices for surface treatment of metal fasteners are mostly open cooling tunnels. The surface-treated metal fasteners are cooled uniformly through cold air channels. However, because they are always in an open state, the cold air resources are seriously wasted, which increases the long-term power consumption of the equipment and makes them relatively impractical. Therefore, those skilled in the art have proposed a rapid cooling device for surface treatment of metal fasteners. Utility Model Content

[0034] Working Principle: This utility model is equipped with an mounting platform 3, a support platform 4, a cooling tray 5, and a cooling cover 7. The mounting platform 3 is welded to the top surface of the mounting base plate 2, and a conveyor shaft 1 is symmetrically mounted on the mounting platform 3. A conveyor roller 6 is fixedly mounted on the conveyor shaft 1, and a thick conveyor belt 16 is sleeved between the two conveyor rollers 6. A servo motor 17 is bolted to one side of the mounting platform 3, and the output end of the servo motor 17 is keyed to one end of the conveyor shaft 1. The support platform 4 is welded to the mounting platform 3 and is located inside the thick conveyor belt 16. Several limiting placement grooves 15 are evenly opened on the surface of the thick conveyor belt 16. A placement mesh plate 27 is welded and fixed to the inner cavity of the cooling tray 5, and several air vents 2 are evenly opened on both side walls of the cooling tray 5. 8. In use, place the surface-treated metal fasteners on the placement mesh plate 27, and then insert the cooling tray 5 into the limiting placement groove 15. When the servo motor 17 is started to drive the conveyor shaft 1 to rotate, the thick conveyor belt 16 and the cooling tray 5 will move together. The mounting base plate 2 is equipped with a fixed frame 9 welded to the top surface, and an electric push rod 12 is bolted to the center of the top surface of the fixed frame 9. The output end of the electric push rod 12 is bolted to a lifting plate 8. The bottom surface of the lifting plate 8 is symmetrically welded with a cooling cover 7. The top of the inner cavity of the cooling cover 7 is fixedly installed with a gas distribution box 25, and several gas distribution nozzles 26 are evenly installed on the bottom surface of the gas distribution box 25. The fixed frame 9 is equipped with a cooling fan 10, and the output end of the cooling fan 10 is connected to a telescopic connector. One end of the flexible hose 14 and the other end of the telescopic flexible hose 14 are connected to the inner cavity of the air distribution box 25. When the cooling tray 5 moves above the support platform 4 and below the fixed frame 9, the electric push rod 12 drives the lifting plate 8 to move downward until the cooling cover 7 aligns with the cooling tray 5, and the sealing ring 29 fixedly installed on the bottom surface of the cooling cover 7 is embedded in the sealing groove 30 opened on the top of the cooling tray 5. At this time, the cooling fan 10 is started, and the generated dry cold air is delivered to the inner cavity of the air distribution box 25 through the telescopic flexible hose 14, and finally evenly sprayed onto the surface of the metal fastener through several air distribution nozzles 26, thereby achieving rapid cooling of the surface treatment of the metal fastener, ensuring the surface treatment quality of the metal fastener, and the metal fastener is in the sealed space formed by the cooling tray 5 and the cooling cover 7. This significantly reduces the loss of cold air volume due to leakage, which helps reduce the power consumption of the equipment during long-term operation. The fixed frame 9 has symmetrically fixed return air pipes 19 on both sides, with one end of the return air pipe 19 connected to a gas collection hood 18, and the other end connected to the input end of the cooling fan 10. As described above, the cold air sprayed through the uniform air nozzle 26 enters the inner cavity of the cooling tray 5. After the dry cold air rapidly cools the metal fasteners, it can be discharged through the air outlet 28. The discharged cold air is recovered through the gas collection hood 18. A drying chamber 20 is connected to the return air pipe 19, and a breathable mesh frame 21 is fixedly installed inside the drying chamber 20. A molecular sieve 22 is placed inside the breathable mesh frame 21, which can absorb and recover moisture from the cold air.By reducing the humidity of the recovered cold air, it can be recirculated into the refrigeration fan 10, further reducing cooling loss and enhancing its practicality.
