[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-4 The electroplating apparatus for galvanized steel wire processing shown includes an electroplating tank 1 and a first electrode plate 2 installed inside the electroplating tank 1.

[0028] The electroplating tank 1 is equipped with multiple fixing rods 8 inside;

[0029] Multiple fixing rods 8 have support rods 13 fixedly connected to the bottommost side of the outer walls at both ends of the front and rear ends to support the steel wire;

[0030] Multiple support rods 13 are fixedly connected to limit rods 12 on their upper outer walls. First, an appropriate amount of zinc salt, conductive salt, buffer, and additives are dissolved in water and stirred evenly to ensure that the composition and concentration of the electroplating solution meet the process standards. Then, the prepared electroplating solution is slowly poured into the electroplating tank 1 to reach the specified liquid level. Subsequently, the pre-treated steel wire is coiled up and placed on the support rod 13 and positioned by the limit rod 12. Then, the first electrode plate 2 is connected to the positive terminal of the power supply, and the steel wire to be galvanized is connected to the negative terminal of the power supply through a conductive device to form a complete circuit. When the power is turned on, the electroplating reaction begins. The zinc on the first electrode plate 2 begins to dissolve, releasing zinc ions into the electroplating solution. Under the action of the electric field, the zinc ions move towards the steel wire, gain electrons on the surface of the steel wire and deposit there, gradually forming a zinc plating layer. When the set electroplating time is reached, the power is turned off, and the zinc-plated steel wire is carefully removed from the support rod 13. Then, the electroplating process of the next batch of steel wire is carried out.

[0031] The electroplating tank 1 is equipped with multiple second electrode plates 16. During the electroplating process, due to the effect of the second electrode plates 16, the electric field distribution on the surface of the steel wire is optimized, the current density is more uniform, and the zinc ions are uniformly deposited on the surface of the steel wire.

[0032] like Figure 3 and Figure 4As shown, the inner walls of the front and rear ends of the first electrode plate 2 are fixedly connected with fixed tubes 14. One end of the opposite side of each fixed tube 14 is fixedly connected with a connecting rod 18. The outer walls of the upper and lower ends of each connecting rod 18 are fixedly connected with shunt tubes 15. One side of each of the multiple second electrode plates 16 is fitted with a fixed sleeve 17. The multiple shunt tubes 15 and the fixed sleeves 17 are fixedly connected to restrict the position of the second electrode plates 16. The interiors of the multiple fixed tubes 14, shunt tubes 15 and connecting rods 18 are hollow to allow the circuit to pass through.

[0033] The connecting rod 18 connected to one end of the fixed tube 14 further extends the connecting structure. The diversion tubes 15 connected to the outer walls of its upper and lower ends form a stable frame structure. These components are interconnected, providing a basic framework for the positioning of the second electrode plate 16. During the operation of the electroplating device, it is necessary to provide power connection to the first electrode plate 2 and the second electrode plate 16. The hollow structure allows wires to pass through it, connecting the electrode plates to the power system, ensuring that the current can be smoothly transmitted to each electrode plate so that they can work normally.

[0034] like Figure 1 As shown, brackets 4 are fixedly connected to the upper outer wall of the electroplating tank 1 and near the left and right sides respectively. A driver 3 is provided on one side of each of the two brackets 4. A drive rod 5 is provided inside the upper outer wall of each of the two brackets 4. A top plate 7 is provided between the upper outer walls of the two drive rods 5 to limit the position of the fixed rod 8. A guide rod 6 is provided inside the two brackets 4 near the rear side to limit the movement direction of the top plate 7.

[0035] The driver 3 drives the drive rod 5 located inside the upper outer wall of the bracket 4 to move. The top plate 7, which is set between the upper outer walls of the drive rod 5, is connected to the drive rod 5. When the drive rod 5 moves, the top plate 7 moves accordingly, fixing the fixing rod 8 in a specific position. This ensures that the fixing rod 8 will not move arbitrarily during the electroplating process, thereby ensuring the stability of the position of the steel wire supported on the fixing rod 8. This is beneficial to the uniformity and stability of electroplating. The up and down movement of the top plate 7 drives the steel wire to enter and exit the liquid. When the driver 3 drives the drive rod 5 to move the top plate 7, the guide rod 6 guides the top plate 7 to move only in a specific direction, preventing the top plate 7 from shifting or shaking during the movement.

[0036] like Figure 1 As shown, a control device 10 is provided on the front outer wall of the electroplating tank 1. A display screen 9 is embedded inside the front outer wall of the control device 10. An alarm port 11 is provided at the lower right corner of the front outer wall of the control device 10 to issue an alarm after an abnormality is detected.

[0037] By using the operation buttons of the control device 10, the normal range of various electroplating parameters is preset according to the electroplating process requirements. The display screen 9 is started and initialized. The display interface is initialized and ready to receive and display real-time data from the control device 10. When an abnormal situation is detected, the microprocessor triggers the alarm system and sends an alarm signal to the alarm port 11. The sound-emitting device in the alarm port 11 emits a loud alarm sound to attract the attention of the operator.

[0038] The implementation principle of this embodiment is as follows: First, an appropriate amount of zinc salt, conductive salt, buffer, and additives are dissolved in water and stirred evenly to ensure that the composition and concentration of the electroplating solution meet the process standards. Then, the prepared electroplating solution is slowly poured into the electroplating tank 1 until the specified liquid level is reached. Subsequently, the pre-treated steel wire is coiled up and placed on the support rod 13 and positioned by the limiting rod 12. Then, the first electrode plate 2 is connected to the positive terminal of the power supply, and the steel wire to be galvanized is connected to the negative terminal of the power supply through a conductive device to form a complete circuit. The power is then turned on, and electroplating begins. The reaction begins, and the zinc on the first electrode plate 2 begins to dissolve, releasing zinc ions into the electroplating solution. Under the action of the electric field, the zinc ions move towards the steel wire, gain electrons on the surface of the steel wire and deposit there, gradually forming a zinc plating layer. When the set electroplating time is reached, the power is turned off, and the zinc-plated steel wire is carefully removed from the support rod 13. Then, the electroplating process for the next batch of steel wires is carried out. During the electroplating process, due to the action of the second electrode plate 16, the electric field distribution on the surface of the steel wire is optimized, the current density is more uniform, and the uniform deposition of zinc ions on the surface of the steel wire is promoted.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
