Description

Technical Field

[0001] This utility model relates to the technical field of metal wire processing and manufacturing, and in particular to a cooling device for tin-plated copper wire. Background Technology

[0002] The tin-plated copper wire cooling device is a key piece of equipment in the wire and cable manufacturing process. It is mainly used to rapidly and uniformly cool the copper wire after the hot-dip tin plating process is completed.

[0003] In related technologies, existing tin-plated copper wire cooling devices mostly employ simple water tank immersion or spray structures. However, in practical applications, the cooling water is unevenly distributed during the cooling process, preventing the high-temperature wire from forming a stable heat exchange with the low-temperature medium throughout the cooling path. This results in slow, inefficient, and uneven cooling of the wire. Furthermore, the unorganized water flow leads to varying cooling rates at different locations on the wire, resulting in coarse grain structure, reduced surface smoothness, and weakened adhesion stability between the tin layer and the copper wire. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a cooling device for tin-plated copper wire, which adopts a counter-current cooling and closed-loop structure. By utilizing the counter-current flow of the cooling medium and the wire, the heat exchange efficiency is improved, achieving efficient and uniform rapid cooling. This effectively improves the surface finish of the tin-plated copper wire and enhances the adhesion stability between the tin layer and the copper wire.

[0006] To achieve the above objectives, this utility model proposes a tin-plated copper wire cooling device, comprising a storage box, a circulation component, and a counter-current cooling component. The circulation component is disposed on the storage box, and the counter-current cooling component includes a cooling box and multiple sets of symmetrically arranged limiting rollers. The cooling box is disposed inside the storage box, and the multiple sets of symmetrically arranged limiting rollers are rotatably connected between the opposite inner walls of the storage box and located inside the cooling box.

[0007] In addition, the tin-plated copper wire cooling device proposed above according to this utility model may also have the following additional technical features: Specifically, the storage box has an inlet and an outlet on both sides, and the cooling box has a first through hole and a second through hole on both sides, with the first through hole and the second through hole being at the same height as the inlet and the outlet.

[0008] Specifically, the circulation assembly includes a pressure box, a first driving device, and a connecting pipe. The pressure box is disposed on the storage box and located above the cooling box. The first driving device is disposed on the pressure box and its output end is connected to the pressure box. The connecting pipe is disposed between the input end of the first driving device and the storage box.

[0009] Specifically, the bottom of the pressure box has multiple third through holes, and the multiple third through holes correspond to the positions of the cooling box.

[0010] Specifically, a rubber flap is provided inside the second through hole, and a wiping block is provided inside the discharge port.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The tin-plated copper wire cooling device of this utility model adopts a counter-current cooling and closed-loop structure. By reusing the circulation component and promoting the flow of cooling water, the water flow and the wire flow are reversed in conjunction with the cooling box, forming a stable temperature difference with the tin-plated copper wire. This achieves efficient and uniform rapid cooling, avoids micro-stress and surface defects in the tin layer caused by uneven cooling, saves water resources and energy consumption, and adopts a dual drying mechanism composed of rubber flaps and wiping blocks to remove moisture from the surface of the wire at the outlet, eliminating the generation of water stains and ensuring the smoothness and adhesion stability of the tin-plated copper wire surface.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The tin-plated copper wire cooling device of this utility model embodiment will now be described with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown, the tin-plated copper wire cooling device of this utility model embodiment may include a storage box 1, a circulation component 2, and a counter-current cooling component 3.

[0018] The circulation component 2 is located on the storage box 1.

[0019] It should be noted that the storage box 1 described in this embodiment is a rectangular cavity structure with an opening at the top, which can stably support the circulation component 2 and the counterflow cooling component 3, and form a relatively closed cooling water circulation structure.

[0020] The counter-current cooling assembly 3 includes a cooling box 31 and multiple sets of symmetrically arranged limiting rollers 32.

[0021] The cooling box 31 is located inside the storage box 1, and multiple sets of symmetrically arranged limiting rollers 32 are rotatably connected between the relative inner walls of the storage box 1 and located inside the cooling box 31.

[0022] It should be noted that the cooling box 31 proposed in the above embodiment adopts a cavity structure with an open top to receive the deionized cooling water falling from the circulation component 2. Multiple sets of symmetrically arranged limiting rollers 32 are used to support the incoming wire, maintain the incoming wire tension, and realize the guiding and conveying of the tin-plated copper wire.

[0023] Specifically, during the actual cooling process, the relevant personnel placed the device along the direction of the tin-plated copper wire. In the initial state, the storage box 1 contained deionized water, and its height was lower than the inlet 11 and the outlet 12.

[0024] When the wire is fed in, after the tin-plated copper wire comes out, it passes through the feed port 11, the first through hole 311, multiple sets of symmetrically arranged limiting rollers 32, the second through hole 312 and the discharge port 12 in sequence.

[0025] During cooling, the first drive device 22 draws deionized water from the bottom of the storage box 1 through the connecting pipe 23 and pumps it into the pressure box 21. The water is then sprayed downwards through multiple third through holes 211 at the bottom of the pressure box 21 and falls into the cooling box 31. Since the second through hole 312 is blocked by the rubber flap 3121, the water flows out of the cooling box 31 towards the first through hole 311 in the opposite direction to the wire inlet. At the same time, multiple sets of symmetrically arranged limiting rollers 32 are used to continuously guide and transport the tin-plated copper wire during cooling, effectively cooling and reducing its temperature.

[0026] When wiping the surface of the tinned copper wire, it should first contact the rubber flap 3121 to remove most of the moisture from the surface of the tinned copper wire, while avoiding water droplets remaining on the surface of the tinned copper wire. During the moisture removal process, the pulling force should be kept slow and continuous, and the surface moisture protection should prevent friction from damaging the surface of the tinned copper wire. Finally, when the tinned copper wire exits the wire outlet, it contacts the wiping block 121 for secondary moisture removal. The wiping block 121 is made of sponge material, which is low in cost and easy to replace.

[0027] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the storage box 1 has an inlet 11 and an outlet 12 on both sides, and the cooling box 31 has a first through hole 311 and a second through hole 312 on both sides, and the first through hole 311 and the second through hole 312 are set at the same height as the inlet 11 and the outlet 12.

[0028] It should be noted that the first through hole 311, the second through hole 312, the inlet 11 and the outlet 12 described in this embodiment are arranged along the length of the device so that the tin-plated copper wire can pass through effectively and achieve cooling and wiping inside the device.

[0029] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the circulation component 2 includes a pressure box 21, a first drive device 22, and a connecting pipe 23.

[0030] The pressure box 21 is disposed on the storage box 1 and located above the cooling box 31. The first driving device 22 is disposed on the pressure box 21 and the output end of the first driving device 22 is connected to the pressure box 21. The connecting pipe 23 is disposed between the input end of the first driving device 22 and the storage box 1.

[0031] The bottom of the pressure box 21 has multiple third through holes 211, which correspond to the positions of the cooling box 31.

[0032] It should be noted that the first driving device 22 proposed in the above embodiment is a water pump. The water pump draws cooling water from the inside of the storage box 1 through the connecting pipe 23 and pumps it into the pressure box 21 to increase the internal pressure of the pressure box 21. This promotes the cooling water in the third through hole 211 to fall. During the falling process, it briefly exchanges heat with the air to keep the cooling water close to the room temperature. At the same time, it is cooled and transported to the cooling box 31 to achieve the circulation of cooling water.

[0033] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a rubber flap 3121 is provided inside the second through hole 312, and a wiping block 121 is provided inside the discharge port 12.

[0034] It should be noted that the wiping block 121 described in this embodiment is made of sponge material. The moisture on the surface of the galvanized copper wire is first scraped off by the rubber flap 3121, and then pulled out while still wet. It is then wiped a second time by the wiping block 121 to remove residual water stains on the surface of the tin-plated copper wire, which effectively improves the smoothness of the tin-plated copper wire surface and enhances the adhesion stability between the tin layer and the copper wire.

[0035] In summary, the tin-plated copper wire cooling device of this utility model adopts a counter-current cooling and closed-loop structure. By utilizing the counter-current flow of the cooling medium and the wire, the heat exchange efficiency is improved, achieving efficient and uniform rapid cooling. This effectively improves the surface finish of the tin-plated copper wire and enhances the adhesion stability between the tin layer and the copper wire.
