Description

Technical Field

[0001] This utility model relates to the field of copper-clad steel wire technology, specifically to a continuous electroplating device for copper-clad steel wire. Background Technology

[0002] Copper-clad steel refers to a composite wire in which copper is wrapped around steel wire, essentially a steel wire surrounded by a copper layer. It utilizes the skin effect of low-voltage, high-frequency signals, allowing them to travel along the surface in the high-frequency range. Therefore, as long as the copper layer thickness reaches a certain range, signals in a specific frequency band can be reliably transmitted. The copper acts as a conductor of weak electrical signals, while the steel wire provides support. Copper-clad steel wire requires electroplating during production.

[0003] During the electroplating process, impurities that fall off the surface of the copper-clad steel wire and metal debris generated during the electroplating process will inevitably be mixed into the plating solution. These debris tend to remain at the bottom of the electroplating tank, increasing the difficulty of subsequent cleaning. Therefore, a continuous electroplating device for copper-clad steel wire is needed. Utility Model Content

[0004] The purpose of this invention is to provide a continuous electroplating device for copper-clad steel wire, which solves the problems mentioned in the background art.

[0005] This application provides a continuous electroplating device for copper-clad steel wire, including an electroplating tank. A conical recovery port is provided at the bottom of the electroplating tank. A connecting pipe is fixedly connected to the bottom of the conical recovery port. A cylinder is threadedly connected to the bottom of the connecting pipe. A recovery pipe is threadedly connected to the bottom of the cylinder. A support ring is fixedly connected inside the cylinder. An insertion hole is opened on the support ring. A rubber sleeve is fixedly connected inside the insertion hole. A filter screen is provided at the top of the support ring. An insertion rod is fixedly connected to the bottom of the filter screen. The insertion rod is inserted into the insertion hole. The rubber sleeve is sleeved on the outside of the insertion rod.

[0006] In use, the steel wire enters the electroplating tank through the first and second guide wheels. Then, under the action of the external winding device, the steel wire is pulled out and wound up from the inside of the electroplating tank, allowing for continuous electroplating. The conical recovery port allows the plating solution to increase its flow speed under the action of gravity, quickly converging and flowing into the recovery pipe for recycling, preventing plating solution residue from forming at the bottom of the electroplating tank. At the same time, the plating solution passes through the cylinder before entering the recovery pipe. The filter screen inside the cylinder can filter impurities in the plating solution, ensuring the cleanliness and quality of the plating solution. Since the cylinder, conical recovery port, and recovery pipe are all connected by threads, the cylinder can be easily disassembled. Then, the insertion rod at the bottom of the filter screen can be pulled out from the support ring for cleaning. The rubber sleeve increases the friction between the insertion rod and the inner wall of the insertion hole, which helps to improve the firmness of the filter screen installation and prevents it from falling off.

[0007] Optionally, the inner wall of the electroplating tank is fixedly connected to a first mounting bracket and a second mounting bracket, the second mounting bracket being located below the first mounting bracket, the first mounting bracket being rotatably connected to a first guide wheel, and the second mounting bracket being rotatably connected to a second guide wheel.

[0008] By adopting the above technical solution, the first guide wheel and the second guide wheel enable the steel wire to pass through the inside of the electroplating tank for continuous electroplating.

[0009] Optionally, both the first guide wheel and the second guide wheel have an H-shaped vertical cross-section.

[0010] By adopting the above technical solution, it is possible to prevent the steel wire from slipping off the first guide wheel and the second guide wheel.

[0011] Optionally, the conical recovery port is connected to the interior of the electroplating tank, and a valve is installed at the connection point between the conical recovery port and the electroplating tank.

[0012] By adopting the above technical solution, the conical recovery port can be opened or closed via a valve, facilitating the discharge of plating solution.

[0013] Optionally, the diameter of the hole in the rubber sleeve is adapted to the diameter of the insertion rod.

[0014] By adopting the above technical solution, it is beneficial to improve the firmness of the insertion rod inside the insertion hole, thereby improving the firmness of the filter screen installation.

[0015] Optionally, the filter screen is made of stainless steel.

[0016] By adopting the above technical solutions, corrosion resistance was improved and service life was extended.

[0017] Optionally, fluororubber sealing rings are provided at the locations where the cylinder connects to the connecting pipe and the recycling pipe.

[0018] By adopting the above technical solution, it is beneficial to increase the sealing effect of the connection between the cylinder and the connecting pipe and the recovery pipeline. In addition, the fluororubber sealing ring has excellent chemical corrosion resistance, high temperature resistance and weather resistance, which extends the service life.

[0019] Optionally, the cylinder is a hollow cylinder, and the aperture of the cylinder is adapted to the diameter of the filter screen.

[0020] By adopting the above technical solution, it is beneficial to improve the filtration effect of impurities in the plating solution.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application uses a conical recovery port to increase the flow velocity of the plating solution under the action of gravity, allowing it to quickly converge and flow into the recovery pipe for recycling, thus preventing the plating solution from leaving residue at the bottom of the electroplating tank. Simultaneously, before entering the recovery pipe, the plating solution passes through a cylinder, where a filter screen filters out impurities, ensuring the cleanliness and quality of the plating solution and reducing the difficulty of cleaning. Furthermore, the support ring, insert rod, insertion hole, and rubber sleeve enable quick installation and removal of the filter screen, making it convenient and practical.
