In the process of processing steel wire, tin plating is required using a tin plating device.

[0003] The existing equipment requires cleaning the tin plating tank after tin plating. This cleaning requires repeated cleaning with a hand brush, which is cumbersome. If the tin plating tank is deep, the cleaning difficulty is further increased. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-station tin plating device for copper-clad steel wire, which solves the problem that existing devices require cleaning the tin plating tank after tin plating. The cleaning process requires repeated cleaning with a hand brush, which is cumbersome. If the tin plating tank is deep, the cleaning difficulty is further increased.

[0005] The purpose and effectiveness of this utility model's multi-station tin plating device for copper-clad steel wire are achieved through the following specific technical means:

[0006] A multi-station tin plating device for copper-clad steel wire includes a tin plating box; the tin plating box is filled with tin plating liquid, and two conveying rollers rotate on the top of the tin plating box. Each conveying roller has a linear array of annular limiting grooves, which are limiting components for the steel wire. The steel wire is electrically connected to the cathode. A base block is fixed in the middle of the tin plating box by a screw. Two guide rods slide on the base block, and the lower end of each guide rod is welded to a roller seat. A roller rotates on the roller seat. A first hydraulic cylinder is fixed to the bottom end of the base block, and the extended end of the first hydraulic cylinder is fixed to the roller seat.

[0007] Furthermore, two impellers are fixed on the rotating shaft of the roller, and the two impellers together form a mixing structure for the tin plating liquid in the tin plating box.

[0008] Furthermore, the base block, guide rod, roller seat, roller, first hydraulic cylinder, and impeller together form the adjustment assembly.

[0009] Furthermore, a cleaning assembly is installed inside the tin plating box. The cleaning assembly consists of a base, a second hydraulic cylinder, a first sealing block, a connecting rod, a second sealing block, and an auxiliary block. A concave base is welded to the left end face of the tin plating box. A second hydraulic cylinder is fixed to the right end face of the inner wall of the base. A first sealing block is fixed to the extended end of the second hydraulic cylinder. The bottom end face of the first sealing block is flush with the bottom end face of the inner wall of the tin plating box. The first sealing block is inserted into the rectangular cleaning hole on the left end face of the tin plating box.

[0010] Furthermore, a rectangular cleaning hole is also provided on the right end face of the tin plating box corresponding to the left end face; two connecting rods are fixed on the right end face of the first sealing block, and one right end of the two connecting rods is fixed on the second sealing block, which is engaged in the cleaning hole on the right end face of the tin plating box.

[0011] Furthermore, the second sealing block has a stepped structure, with the outer wall of the left side of the second sealing block contacting the inner wall of the cleaning hole on the right end face of the tin plating box, and the left end face of the right side of the second sealing block contacting the right end face of the tin plating box.

[0012] Furthermore, an auxiliary block with a U-shaped structure is welded to the left end face of the tin-plating box, and the left end face of the auxiliary block and the first sealing block are in contact with the right end face of the auxiliary block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, the limiting grooves of the two conveyor rollers at the top of the tin plating box enable simultaneous tin plating at multiple stations, significantly improving tin plating efficiency and meeting the needs of mass production.

[0015] Secondly, the first hydraulic cylinder in the adjustment component can drive the roller to press down, ensuring that the steel wire is fully immersed in the tin plating liquid. The impeller on the roller's rotating shaft can mix the tin plating liquid, making the composition of the tin plating liquid uniform, thereby improving the tin plating effect and quality of the steel wire and ensuring the uniformity and stability of the tin plating layer.

[0016] Thirdly, the design of the cleaning components facilitates the cleaning and maintenance of the tin plating box. The base, second hydraulic cylinder, first sealing block, connecting rod, second sealing block, and auxiliary block work together. The second hydraulic cylinder drives the first and second sealing blocks to move, opening the cleaning holes at both ends of the tin plating box to facilitate the discharge of deposited impurities and residual liquid. At the same time, the stepped structure of the second sealing block, in conjunction with the auxiliary block, effectively improves the sealing performance at the cleaning holes, preventing tin plating liquid leakage, ensuring the normal operation of the tin plating process, extending the service life of the tin plating box, reducing maintenance costs, and minimizing safety hazards and resource waste caused by leakage.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a multi-station tin plating device for copper-clad steel wire, including a tin plating box 1. The tin plating box 1 is filled with tin plating liquid. Two conveying rollers 2 rotate on the top of the tin plating box 1. Each conveying roller 2 has a linear array of annular limiting grooves 201, which serve as limiting components for the steel wire. The steel wire is electrically connected to the cathode. During use, the linear array of limiting grooves 201 enables simultaneous tin plating at multiple stations, improving tin plating efficiency. A base block 301 is fixed in the middle of the tin plating box 1 by a screw. Two guide rods 302 slide on the base block 301. The lower end of each guide rod 302 is welded to the roller seat 303. A roller 304 rotates on the roller seat 303. A first hydraulic cylinder 305 is fixed to the bottom surface of the base block 301. The extended end of the first hydraulic cylinder 305 is fixed to the roller seat 303. During tin plating, the first hydraulic cylinder 305 is driven to extend. The first hydraulic cylinder 305 drives the roller seat 303 and the roller 304 to move downward. The roller 304 can press the steel wire into the tin plating box 1 to achieve tin plating.

[0028] Two impellers 306 are fixed on the rotating shaft of the roller 304. The two impellers 306 together form the mixing structure of the tin plating liquid in the tin plating box 1. When the roller 304 rotates, the tin plating liquid can be mixed through the two impellers 306. The mixing of the tin plating liquid can improve the tin plating effect of the steel wire.

[0029] The base block 301, guide rod 302, roller seat 303, roller 304, first hydraulic cylinder 305 and impeller 306 together form the adjustment assembly 3.

[0030] The tin plating box 1 is equipped with a cleaning component 4, which consists of a base 401, a second hydraulic cylinder 402, a first sealing block 403, a connecting rod 404, a second sealing block 405, and an auxiliary block 406. A concave base 401 is welded to the left end face of the tin plating box 1. A second hydraulic cylinder 402 is fixed to the right end face of the inner wall of the base 401. A first sealing block 403 is fixed to the extended end of the second hydraulic cylinder 402. The bottom end face of the first sealing block 403 is flush with the bottom end face of the inner wall of the tin plating box 1. The first sealing block 403 is inserted into the rectangular cleaning hole on the left end face of the tin plating box 1.

[0031] Among them, a rectangular cleaning hole is also opened on the right end face of the tin plating box 1 at the corresponding position of the left end face; two connecting rods 404 are fixed on the right end face of the first sealing block 403, and one right end of the two connecting rods 404 is fixed on the second sealing block 405, which is snapped into the cleaning hole on the right end face of the tin plating box 1.

[0032] The second sealing block 405 has a stepped structure. The outer wall of the left side of the second sealing block 405 contacts the inner wall of the cleaning hole on the right end face of the tin plating box 1, and the left end face of the right side of the second sealing block 405 contacts the right end face of the tin plating box 1. During use, the stepped structure of the second sealing block 405 can improve the sealing effect on the cleaning hole on the right end face of the tin plating box 1.

[0033] Example 2: Based on Example 1, an auxiliary block 406 with a U-shaped structure is welded to the left end face of the tin-plating box 1. The left end face of the auxiliary block 406 and the right end face of the first sealing block 403 are in contact with each other. During use, the sealing effect at the first sealing block 403 can be improved by the contact between the left end face of the first sealing block 403 and the right end face of the auxiliary block 406.

[0034] Working principle: When tinning the steel wire, the steel wire is conveyed to the right by the conveying roller 2, which drives the first hydraulic cylinder 305 to extend. The first hydraulic cylinder 305 drives the roller seat 303 and the roller 304 to move downward. The roller 304 can press the steel wire into the tinning box 1 to achieve tinning. During the steel wire conveying process, the roller 304 will rotate. When the roller 304 rotates, the tinning liquid can be mixed by the two impellers 306. When cleaning the residue, the second hydraulic cylinder 402 is driven to extend. The second hydraulic cylinder 402 drives the first sealing block 403, the connecting rod 404 and the second sealing block 405 to move to the right. At this time, the residue on the bottom surface of the inner wall of the tinning box 1 can be scraped off by the first sealing block 403.
