[0026] Please see Figs. 1-3 This utility model provides a technical solution: an annealing equipment for producing galvanized steel coils, including a cooling cylinder 1, a support frame 11 provided at the lower end of the inner cavity of the cooling cylinder 1, a fan 12 detachably installed at the upper end of one side of the cooling cylinder 1, a sleeve welded above the support frame 11, a galvanized steel coil body 13 sleeved on the upper end of the support frame 11, a support rod 14 fixedly installed at the lower end of the support frame 11, and a servo motor 2 fixedly installed on the other side of the cooling cylinder 1;

[0027] A transmission rod 21 is installed at the output end of the servo motor 2. A first pulley 22 is fixedly installed at the lower end of the transmission rod 21. A second pulley 24 is fixedly installed at the lower end of the support rod 14. Multiple auxiliary rods 3 are welded to the edge of the support frame 11. A fixing ring 31 is welded to the inner wall of the cooling cylinder 1. An annular groove 32 is opened on the inner side of the fixing ring 31. A ball 4 is welded to the upper end of the auxiliary rods 3. The auxiliary rods 3 are arranged in a ring and are inclined. The support frame 11 can be rotated by the arrangement of the auxiliary rods 3. The auxiliary rod 3 is equipped with multiple fan blades 5 on both sides, which are evenly distributed. The fan blades 5 can be used to agitate the airflow below the cooling cylinder 1. Support wheels 6 are fixedly installed on both sides of the lower end of the support frame 11, and the lower end of the support wheel 6 is in contact with the lower end of the inner cavity of the cooling cylinder 1. The support wheel 6 can also provide support for the support frame 11, making it easier for the support frame 11 to rotate smoothly.

[0028] The size of the ball 4 is matched with the size of the annular groove 32, and the ball 4 and the annular groove 32 are movably connected. Through the cooperation between the ball 4 and the annular groove 32, the stability of the rotation of the auxiliary rod 3 can be guaranteed.

[0029] The first pulley 22 is connected to the second pulley 24 via the transmission belt 23. The first pulley 22 and the second pulley 24 work together to drive the support rod 14 to rotate.

[0030] During annealing, after the galvanized steel coil body 13 has undergone heat treatment, it is hoisted into the cooling cylinder 1, allowing it to fit onto the support frame 11. Then, the fan 12 is turned on, expelling cold air into the cooling cylinder 1. Simultaneously, the servo motor 2 drives the transmission rod 21 to rotate. The first pulley 22 on the transmission rod 21 drives the second pulley 24 to rotate via the transmission belt 23, which in turn drives the support frame 11 to rotate. This causes the galvanized steel coil body 13 on the support frame 11 to rotate within the cooling cylinder 1, thereby improving the cooling uniformity of the galvanized steel coil body 13 and preventing overcooling from affecting the hardness and plasticity of the steel coil. Simultaneously, the rotation of the support frame 11... During operation, the auxiliary rod 3 and the fixed ring 31 work together to ensure the stability of the support frame 11's rotation within the cooling cylinder 1. Simultaneously, due to the sliding design of the auxiliary rod 3 within the fixed ring 31, the weight of the galvanized steel coil body 13 can be shared between the auxiliary rod 3 and the fixed ring 31, ensuring smooth rotation of the support frame 11 and improving the annealing cooling efficiency of the galvanized steel coil body 13. Furthermore, as the auxiliary rod 3 rotates, the fan blades 5 on it also rotate below the cooling cylinder 1, agitating the cold airflow entering the cooling cylinder 1 and altering its flow pattern, further ensuring the cooling efficiency of the galvanized steel coil body 13.
