[0038] Working principle: When the surface quality of the galvanized steel strip needs to be improved, the motor 13 starts working when the controller 20 is started. The two motors 13 work at the same time to make the rotating rod 5 do circular motion through the rotating shaft 4. The sliding block 6 also makes a circular motion to drive the semicircular limit block 9 to move back and forth, thereby allowing the storage plate 8 to move back and forth in the guide rail 7 to fully cool and clean the steel strip. When the motor 2 10 works, it will pull the transmission rod 12 through the connecting rod 11. The sliding block 14 connected to the other end of the transmission rod 12 is also pulled at the same time, allowing the two fixing clamps 15 to move relative to each other, so that the steel strip can be fixed. The fixing device can accurately position and hold the steel strip, reduce position deviation during processing, and improve the size and shape accuracy of the product. The stable fixing device reduces the risk of steel strip movement, thereby reducing the safety hazards of workers' operation. The back and forth moving device can ensure that the galvanized steel strip is cooled and cleaned evenly and thoroughly.

[0039] When the surface quality of the galvanized strip needs to be improved, the pressurized water pump 203 starts working, and the cooling water drawn from the cooling water tank 202 flows into the pressurized nozzle 205 through the connecting pipe 204. The pressurized nozzle 205 sprays the cooling water onto the galvanized strip to accelerate the cooling of the strip. The pressurized water will also remove the attached impurities on the galvanized strip. The air pump 206 draws air into the air nozzle 208 through the air guide pipe 207. The air nozzle 208 sprays gas to form an airflow, which then cleans the dust on the galvanized strip. The cooling water accelerates the cooling speed and temperature of the strip to avoid surface defects caused by uneven cooling. By using high-pressure air, impurities on the surface of the galvanized strip are effectively cleaned to ensure the surface quality of the final product.
