Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, specifically to a wire cleaning device after tin plating. Background Technology

[0002] After tin plating, copper-clad steel wire needs to be washed with water to remove the plating solution from the surface. Because the wire is constantly being washed, the water in the washing tank has an acidic pH value. After the wire passes through the washing tank, there will still be water on the surface. When the wire is then baked at high temperature, the water on the surface and the tin plating layer corrode and oxidize, which can easily lead to discoloration of the surface and affect the quality of the wire. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wire cleaning device after tin plating, which addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A wire cleaning device after tin plating includes a tin plating tank, with an alkaline solution tank and a water washing tank connected sequentially at the tail end of the tin plating tank. A transition tank is provided between the alkaline solution tank and the water washing tank. A liquid suction device is provided above the transition tank. The liquid suction device includes a gantry support mounted on the transition tank. An upper clamping plate and a lower clamping plate are provided inside the gantry support. Sponges are attached to the clamping surfaces of both the upper and lower clamping plates. A cylinder is installed above the gantry support, with the piston end of the cylinder connected to the upper clamping plate. A set of pulleys is symmetrically arranged on both sides inside the gantry support. Pull ropes are threaded through the pulleys, with one end of the pull rope connected to the end of the upper clamping plate and the other end of the pull rope connected to the end of the lower clamping plate.

[0006] Furthermore, the lower clamping plate is longer than the upper clamping plate.

[0007] Furthermore, guide posts are connected to both sides of the upper and lower clamping plates and pass through each other.

[0008] Furthermore, a drainage hole is provided on the lower clamping plate.

[0009] Furthermore, guide wheels are installed inside the tin plating tank, alkaline solution tank, and water washing tank, and transition wheels are installed at the openings of the tin plating tank, alkaline solution tank, transition tank, and water washing tank.

[0010] Compared with the prior art, the present invention provides a wire cleaning device after tin plating. After tin plating, the wire is washed in an alkaline bath to neutralize the acid and avoid acidic plating solution residue. The excess alkaline solution on the surface of the wire is removed by a liquid suction device, and then the wire is washed with water. This reduces the impact of alkaline solution on water washing and ensures the quality of the wire. Attached Figure Description

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0015] like Figure 1 and Figure 2 As shown, a wire cleaning device after tin plating includes a tin plating tank 1, with an alkaline solution tank 2 and a water washing tank 3 connected sequentially to the tail of the tin plating tank 1. The alkaline solution tank 2 stores alkaline solution for alkali washing of the tin-plated wire. The water washing tank 3 stores clean water for rinsing the wire. To reduce the amount of alkaline solution entering the water washing tank 3, a transition tank 4 is provided between the alkaline solution tank 2 and the water washing tank 3. A liquid suction device is provided above the transition tank 4 to absorb the alkaline solution on the surface of the wire and collect it into the transition tank 4.

[0016] The liquid suction device includes a gantry bracket 5, which is fixed to the transition groove 4 on both sides by screws. An upper clamping plate 6 and a lower clamping plate 7 are provided inside the gantry bracket 5. Sponges 8 are attached to the clamping surfaces of both the upper and lower clamping plates 6 and 7. The wire passes between the sponges, and the sponges 8 absorb the alkaline solution from the surface of the wire. A cylinder 9 is installed above the gantry bracket 5. A connector is provided on the surface of the upper clamping plate 6, and the piston end of the cylinder 9 is connected to the connector on the surface of the upper clamping plate 6. A set of pulleys 10 are symmetrically arranged on both sides inside the gantry bracket 5. Each of the upper and lower clamping plates is equipped with a pull rope 11. One end of the pull rope 11 is connected to the end of the upper clamping plate 6. Since the length of the lower clamping plate 7 is greater than that of the upper clamping plate 6, both ends of the lower clamping plate 7 protrude outward. The other end of the pull rope 11 is connected to the end of the lower clamping plate 7. In this way, during the operation of the cylinder 9, the upper clamping plate 6 and the lower clamping plate 7 are brought closer together or opened. When the upper clamping plate 6 and the lower clamping plate 7 are brought closer together, the alkaline solution absorbed in the sponge 8 can be squeezed out. The lower clamping plate 7 is provided with a drain hole 12. The squeezed alkaline solution drips down along the drain hole 12 and flows into the transition groove 4.

[0017] The upper clamping plate 6 is connected to a guide post 13, the end of which passes through the lower clamping plate 7. The lower clamping plate 7 is connected to a guide post 2 14, the end of which passes through the upper clamping plate 6. By setting the guide post 13 and the guide post 2 14, the upper clamping plate 6 and the lower clamping plate 7 are made more stable during movement.

[0018] Guide rollers 15 are installed in the tin plating tank 1, alkali tank 2, and water washing tank 3. Transition rollers 16 are installed at the openings of the tin plating tank 1, alkali tank 2, transition tank 4, and water washing tank 3. The guide rollers 15 and transition rollers 16 are used to make the wire pass through the tin plating tank 1, alkali tank 2, water washing tank 3, and liquid suction device.

[0019] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
