Description

Technical Field

[0001] This utility model relates to the field of tin plating machine technology, specifically an annealing tin plating machine. Background Technology

[0002] The annealing tin plating machine is an industrial piece of equipment used for continuous annealing, softening, and tin plating of single copper wires, primarily for processing copper wires with diameters ranging from 0.10 to 0.80 mm. This equipment is manufactured by several companies, such as Zhangjiagang Leqiang Machinery Manufacturing Co., Ltd., Wuxi Leiying Electromechanical Co., Ltd., and Jiangsu Jiacheng Technology Co., Ltd. Different models vary in technical parameters, including the wire diameter they can handle. The annealing tin plating machine employs continuous electric heating softening combined with steam or water seal protection, and uses a dual-furnace hot-dip tin plating method.

[0003] An existing annealing tin plating machine with application number 202420971005.8 includes an operating table and support frames symmetrically arranged on the operating table. The tin plating chamber is equipped with a metal wire guide ring and an exhaust pipe. Through the cooperation between the processing component and the filter component, the toxic gases generated during tin plating are treated. The treated gas can enter the annealing chamber through the ventilation pipe for secondary use. At the same time, the surface of the tin-plated metal wire is fully treated by air cooling during the annealing cooling process. The treated gas can also cool the tin-plated metal wire after entering the annealing chamber before being discharged into the air. However, the cooling method of the tin-plated wire is singular, resulting in poor cooling efficiency. Utility Model Content

The wires passing through the second inlet pass through multiple third guide wheels, pass through the bottom of the water-cooling tank, and are discharged from the second water-cooling outlet. This allows the wires that have been dried by hot air during tin plating to be transferred back to the water-cooling tank for further water cooling, thereby improving the cooling efficiency of the tin-plated wires.

[0013] 2. This utility model has an air supply pipe provided through the first exhaust port at the top of the heating box, the first purification box, and the exhaust fan. One end of the air supply pipe is connected to the drying air inlet on the side wall of the tin plating bath, which enables the wires that have completed the high-temperature drying of tin plating hot air to be air-cooled.

The first exhaust port 6 at the top of the heating box 1 is provided with an air conveying pipe 9 through a first purification box 7 and an exhaust fan 8. One end of the air conveying pipe 9 is connected to the drying air inlet 10 on the side wall of the tin plating pool 3, so that the hot air in the heating box 1 can be delivered to the discharge end of the tin plating pool 3 for drying the tin-plated wires, which is beneficial to improving the quality of zinc plating. At the same time, no additional drying equipment is required, which improves resource utilization and facilitates energy saving.

[0022] like Figure 1 and Figure 2 As shown, in order to improve the cooling efficiency of the wires after hot air high-temperature drying following tin plating, the wires led out from the tin plating outlet 16 are introduced into the second feed inlet 17 of the water cooling tank 4 via the second guide wheel 18. The wires passing through the second feed inlet 17 pass through the bottom of the water cooling tank 4 via multiple third guide wheels 21 and are discharged from the water-cooled second outlet 15.

[0025] The working principle and usage process of this utility model are as follows: In use, the wire to be galvanized is entered into the heating box 1 through the wire inlet for electric heating treatment. Then, the wire at the discharge end of the heating box 1 passes through multiple first guide wheels 12, passes through the bottom of the water-cooled pool 4, and is discharged upward through the water-cooled first discharge port 5. It then enters the tin plating tank of the tin plating pool 3 through the tin plating inlet 19 and the guide wheel for tin plating treatment. Moreover, the first exhaust port 6 at the top of the heating box 1 is equipped with an air conveying pipe 9 through the first purification box 7 and the exhaust fan 8.
