Description

Technical Field

[0001] This utility model relates to the field of copper wire tin plating furnace technology, specifically to an online tin plating device for corrosion-resistant filter screen copper wire. Background Technology

[0002] Copper wire mesh is a filter screen made by weaving and welding copper wire. In order to extend the service life of copper wire mesh and improve its corrosion resistance, a layer of tin is usually plated on the surface of the copper wire during processing. This tin protects the copper wire in the event of corrosion and prevents it from corroding.

[0003] Tin plating of copper wire generally requires a tin plating furnace. The furnace uses a high-temperature electrically heated tin plating furnace to heat molten tin, which then coats the surface of the copper wire, completing the online tin plating process. In existing technologies, during the tin plating process, tin dross forms on the surface of the molten tin after a period of use. This dross easily adheres to the surface of the copper wire exiting the tin plating pot. At this point, the tin is not firmly attached to the copper wire surface and cannot be directly removed by pulling it off with a die. This dross adheres to the copper wire, affecting its quality, and necessitates periodic dross removal, thus impacting the tin plating process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an online tin-plating device for corrosion-resistant filter copper wire, which solves the problem that tin dross generated by molten tin during the tin plating process of filter copper wire in a tin plating furnace easily adheres to the surface of the copper wire, affecting its quality.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A corrosion-resistant filter screen copper wire online tin plating device includes a tin plating furnace body, a tin plating pot is provided inside the tin plating furnace body, and inclined plates are provided on both sides of the top of the tin plating pot. The tin plating pot and the inclined plates are sealed without gaps with the inner wall of the tin plating furnace body. Guide wheels for guiding copper wires are provided on both sides of the tin plating furnace body, and pressure rollers are provided inside the tin plating pot. Limit seats are installed at equal intervals along the direction parallel to the guide wheels on the inclined plate on the downstream side of the copper wire conveying. The copper wire passes through the upper part of the guide wheel, the lower part of the pressure roller, passes through the limit seat and passes through the upper part of the guide wheel on the downstream side in sequence from upstream to downstream.

[0007] An impeller perpendicular to the direction of the copper wire is installed above the main body of the tin plating furnace. One end of the impeller is connected to a drive motor installed on the main body of the tin plating furnace. The bottom of the impeller blade is in contact with or immersed in the molten tin in the tin plating pot. A slag baffle plate corresponding to the height of the molten tin is installed in the tin plating pot. The slag baffle plate is located on the side of the impeller near the upstream of the copper wire conveyor.

[0008] Preferably, a fixed frame is fixedly connected to the top of the tin plating furnace body, and the pressure roller is mounted on the bottom of a vertically installed support frame on the fixed frame.

[0009] Preferably, there are two sets of impellers and drive motors, with the two sets of impellers symmetrically arranged on both sides of the fixed frame.

[0010] Preferably, a cover plate fixedly connected to a fixed frame is provided above the pressure roller.

[0011] Preferably, the drive motor is a servo motor.

[0012] Preferably, the slag baffle is inclined, and the height of the slag baffle on the side closer to the impeller is less than the height on the side away from the impeller.

[0013] Preferably, the depth to which the bottom of the impeller blade is immersed in the molten tin does not exceed the width of the blade.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention utilizes an impeller positioned above the molten tin in a tin-plating pot. Copper wires are conveyed from right to left, and the impeller rotates counterclockwise, causing the upper layer of molten tin in the pot to flow to the right. This causes the floating tin dross on the surface of the molten tin to flow to the right side of a baffle plate and be intercepted. Meanwhile, the molten tin in the lower part of the pot, away from the impeller, can flow from right to left, forming a circulation. This process collects and intercepts the floating tin dross on the surface of the molten tin, preventing it from contacting the surface of the copper wires output from the left. This avoids tin dross adhering to the surface of the copper wires, improves the quality of the copper wires, and solves the problem in existing technologies where tin dross generated by the molten tin during the tin-plating process easily adheres to the surface of the copper wires, affecting their quality.

[0020] 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.

[0021] like Figure 1-3 As shown, this utility model provides a technical solution: an online tin plating device for corrosion-resistant filter copper wire, including a tin plating furnace body 1, a tin plating pot 2 is provided inside the tin plating furnace body 1, and inclined ramps 3 are provided on both sides of the top of the tin plating pot 2. The tin plating pot 2 and the inclined ramps 3 are sealed without gaps with the inner wall of the tin plating furnace body 1, and guide wheels 5 for guiding copper wires 4 are provided on both sides of the tin plating furnace body 1.

[0022] The tin plating pot 2 is equipped with a pressure roller 6 inside. The top of the tin plating furnace body 1 is fixedly connected to a fixed frame 11. The pressure roller 6 is installed on the bottom of the vertically installed support frame 12 on the fixed frame 11. The limit seat 7 is installed at equal intervals on the slope plate 3 on the downstream side corresponding to the copper wire 4, along the direction parallel to the guide wheel 5. The copper wire 4 passes through the upper part of the guide wheel 5, the lower part of the pressure roller 6, the limit seat 7, and the upper part of the guide wheel 5 on the downstream side in sequence from upstream to downstream.

[0023] An impeller 8 perpendicular to the direction of the copper wire 4 is installed above the tin plating furnace body 1. One end of the impeller 8 is connected to the drive motor 9 installed on the tin plating furnace body 1. The drive motor 9 is a servo motor. There are two sets of impellers 8 and drive motor 9. The two sets of impellers 8 are symmetrically arranged on both sides of the fixed frame 11. A cover plate 13 fixedly connected to the fixed frame 11 is provided above the pressure roller 6.

[0024] The bottom of the blade of the impeller 8 is in contact with or immersed in the molten tin in the tin plating pot 2. The depth of the bottom of the blade of the impeller 8 immersed in the molten tin does not exceed the width of the blade. A slag baffle 10 corresponding to the height of the molten tin is installed in the tin plating pot 2. The slag baffle 10 is located on the side of the impeller 8 near the upstream of the copper wire 4. The slag baffle 10 is inclined, and the height of the side of the slag baffle 10 near the impeller 8 is less than the height of the side away from the impeller 8.

[0025] Working principle:

[0026] By setting an impeller 8 above the molten tin in the tin plating pot 2, the copper wire 4 is conveyed from right to left. The impeller 8 rotates counterclockwise, causing the upper layer of molten tin in the tin plating pot 2 to flow to the right. This causes the tin dross floating on the surface of the molten tin to flow to the right side of the baffle plate 10 and be intercepted. Meanwhile, the molten tin in the lower part of the tin plating pot 2 is away from the impeller 8 and can flow from right to left, forming a circulation. This collects and intercepts the tin dross floating on the surface of the molten tin and places it on the right side of the baffle plate 10, preventing it from contacting the surface of the copper wire 4 output from the left and avoiding the adhesion of tin dross to the surface of the copper wire 4.
