Description

Technical Field

[0001] The present invention relates to a spraying device and method for separating copper and tin from tinned copper wires, and particularly relates to the technical field of copper-tin separation of copper wires. Background Art

[0002] In the fields of electronics, electrical engineering, and waste metal recycling, tinned copper wires are a commonly used conductive material, and the copper-tin separation technology involved in their recycling process is crucial; traditional methods such as chemical leaching, smelting, etc. are not only complex in process and high in cost, but may also have an adverse impact on the environment; with the enhancement of environmental awareness and the development of technology, the industry has an urgent need for more efficient, economical, and environmentally friendly copper-tin separation technologies.

[0003] Although traditional chemical methods can effectively remove the tin layer, they require the use of a large amount of chemicals, and these chemicals will produce wastewater after treatment, increasing the treatment cost and environmental burden; heat treatment or smelting, this method is suitable for large-scale production, but it is not flexible enough for the treatment of small batches or multi-variety tinned copper wires, and has high energy consumption; some traditional equipment can only process tinned copper wires of specific specifications, and for copper wires of different diameters, shapes, or special materials, additional adjustments or customized designs are often required, restricting their versatility and flexibility.

[0004] Manually stripping the outer skin of copper wires is inefficient and labor-intensive, and is not suitable for modern large-scale industrial applications; in addition, when separating copper and tin from broken or intact and non-compliant copper wires, different types of equipment need to be selected to complete the separation, so the switching of separation methods cannot be completed on one device; secondly, the position of the spraying component cannot be adjusted according to needs, resulting in incomplete cleaning. Summary of the Invention

[0005] Object of the Invention: One object is to propose a spraying device for separating copper and tin from tinned copper wires to solve the above problems existing in the prior art; a further object is to propose a method for implementing the above spraying device.

[0006] Technical Solution: A spraying device for separating copper and tin from tinned copper wires, comprising:

[0007] A cabin, a filter cartridge installed in the cabin, a spraying component installed in the filter cartridge and connected to the cabin, and a wire splitting component installed on one side of the cabin.

[0008] The spray component includes a first hollow shaft and a second hollow shaft that support the filter cartridge and penetrate the cabin body. A third hollow shaft is further provided inside the first hollow shaft. A first gear, a rotary joint, and a box body are sequentially sleeved on the first hollow shaft. Two racks that are slidably installed inside the box body are provided inside the box body. A pipeline is provided on the racks, and a plurality of nozzles are provided on the pipeline. A second gear and a third gear are sequentially sleeved on the third hollow shaft. A spring and a collar are sequentially sleeved on the second gear.

[0009] The profiling component includes an upper component and a lower component that are symmetrically installed on one side of the cabin body. The upper component includes a bracket installed on one side of the cabin body, a worm gear and a worm installed on the bracket, a moving plate installed on the transmission shaft of the worm gear, and a sprocket and a cutter installed on the moving plate.

[0010] In a further embodiment, one end of the filter cartridge is movably connected to the first hollow shaft, and the other end of the filter cartridge is fixedly connected to the second hollow shaft that extends out of the cabin body. A fourth gear is provided at the position where the second hollow shaft extends out of the cabin body. Driving motors are installed on the cabin body at both the fourth gear and the first gear. The position where the second hollow shaft extends out of the cabin body is the outlet. The cabin body is further provided with a feed inlet and a discharge outlet. A cover plate hinged to the filter cartridge is provided at the feed inlet of the filter cartridge.

[0011] In a further embodiment, both the first hollow shaft and the second hollow shaft are movably connected to the cabin body. The third hollow shaft is movably connected to the first hollow shaft. The first gear and the rotary joint are both in interference fit with the first hollow shaft. The rotary joint is arranged between the cabin body and the filter cartridge. The rotary joint is further provided with a pipeline, and the pipeline passes through the first hollow shaft and is communicated with the pipeline inside the box body.

[0012] In a further embodiment, the pipeline is arranged parallel to the first hollow shaft. The two racks are arranged parallel to each other and meshed with the third gear.

[0013] In a further embodiment, both the second gear and the third gear are in interference fit with the third hollow shaft. The third hollow shaft extends out of the first hollow shaft by a certain distance and the extension is the inlet. The second gear is installed at the extension of the third hollow shaft and is located on one side of the first gear. A gap is left between the second gear and the first gear. The second gear and the first gear have the same number of teeth. The third gear is located inside the box body. Both ends of the spring are connected to the third hollow shaft and the collar respectively. The collar is slidably fitted with both the second gear and the first gear.

[0014] In a further embodiment, the bracket is threadedly connected to the cabin body, the worm gear meshes with the worm, both the worm gear and the worm are movably connected to the bracket, and one end of the worm is provided with a servo motor mounted on the bracket; the moving plate meshes with the transmission shaft and is slidably connected to the bracket.

[0015] A spraying method for separating copper and tin from tinned copper wire, used to implement the spraying device, includes:

[0016] First, according to the specifications of the copper wire to be processed, adjust the position of the worm gear and worm drive to adapt to copper wires of different sizes; before the copper wire enters the filter cartridge, it is first precisely cut by the wire splitting assembly to expose the tin layer. The servo motor drives the worm to rotate, and through the worm gear drive, the grooved wheel and cutter on the moving plate perform precise cutting actions; the cutter accurately cuts into the surface of the copper wire without damaging the copper core, preparing for subsequent spraying.

[0017] When separating broken or fractured tinned copper wire, open the cover plate at the feed inlet, send the broken or fractured tinned copper wire through the feed inlet, and then perform preliminary screening to remove larger fragments and other impurities; after screening, spray the copper wire for the first spraying treatment to remove some loose tin layers.

[0018] When separating the complete tinned copper wire, introduce the completely cut tinned copper wire into the filter cartridge through the inlet. The inlet allows the copper wire to pass through smoothly and enter the interior of the filter cartridge without prior crushing; when the third hollow shaft needs to separately adjust the position of the pipeline in the box body, move the collar to separate it from the first hollow shaft, and then rotate the third hollow shaft to drive the third gear to drive the rack to move, causing the pipeline to move. After adjustment, under the action of the spring, the collar moves and the third hollow shaft rotates synchronously with the first hollow shaft.

[0019] The drive motor is started, driving the fourth gear and the first gear to rotate, and then the second hollow shaft and the first hollow shaft rotate at the set speeds respectively; the second hollow shaft drives the box body to rotate around the copper wire, enabling the spray head to contact the copper wire in all directions.

[0020] The spraying liquid is introduced into the first hollow shaft through the rotary joint, and then transmitted through the pipeline to the pipeline in the box body; the multiple spray heads on the pipeline move along a specific path with the cooperation of the rack and the third gear, ensuring that the spraying liquid evenly covers the copper wire; during the spraying process, the tin layer is gradually removed and separated from the copper wire, and the separated tin is discharged from the discharge port through the collection system. The discharge port is also responsible for discharging the processed copper wire, ensuring that the clean copper wire can be smoothly removed.

[0021] Beneficial effects: The present invention provides a spraying device and method for separating copper and tin from tinned copper wires. The cabin provides a closed working environment, ensuring that the liquid does not leak during the spraying process and protecting the safety of operators. The filter cartridge is used to load the crushed tinned copper wires, ensuring that the spraying liquid can evenly cover the copper wires. The first, second, and third hollow shafts guide the complete copper wires, enabling them to be smoothly introduced from the outside into the interior of the filter cartridge, achieving uniform spraying without the need for crushing. The engagement of the rack and the third gear enables the nozzle to move along a specific path, enhancing the spraying effect. The rotary joint allows the first hollow shaft to rotate relative to the cabin while maintaining the connectivity of the internal pipeline. The worm gear and worm provide precise angle adjustment capabilities, enabling the cutter to accurately cut into the copper wire without damaging the copper core. The drive motor controls the rotation of the first hollow shaft and the second hollow shaft, thereby independently driving the rotation of the filter cartridge and the box body.

[0022] By adjusting the worm gear and worm to adapt to copper wires of different diameters, there is no need to customize equipment separately for each type of copper wire. The first hollow shaft can flexibly adjust the distance between the nozzle and the copper wire, ensuring that the spraying liquid can fully cover the surfaces of copper wires of various diameters or shapes, enhancing the versatility and flexibility of the equipment. The second hollow shaft drives the entire box body to rotate, causing the nozzle to move in a circular motion around the copper wire, ensuring that the spraying liquid is evenly distributed on the entire surface of the copper wire, improving the consistency and efficiency of the treatment. The third hollow shaft drives the crushed copper wires in the filter cartridge to rotate synchronously, increasing the relative movement between the copper wires and the spraying liquid, helping to more thoroughly remove the tin layer and improving the separation efficiency.

The rotary joint 311 is also provided with a pipeline, and the pipeline passes through the first hollow shaft 31 and is communicated with a pipeline 323 inside the box body 312; the pipeline 323 is arranged parallel to the first hollow shaft 31.

The third hollow shaft 32 extends out of the first hollow shaft 31 by a certain distance and the extension is an inlet 3. The second gear 325 is installed at the extension of the third hollow shaft 32 and is located on one side of the first gear 313. A gap is left between the second gear 325 and the first gear 313. The second gear 325 and the first gear 313 have the same number of teeth. The third gear 321 is located inside the box body 312. Both ends of the spring 34 are connected to the third hollow shaft 32 and the collar 33 respectively. The collar 33 is slidably fitted with both the second gear 325 and the first gear 313.

[0038] The profiling component includes an upper component and a lower component symmetrically installed on one side of the cabin 1. The upper component includes a bracket 2 installed on one side of the cabin 1, a worm gear 22 and a worm 21 installed on the bracket 2, a moving plate 23 installed on the transmission shaft of the worm gear 22, and a sprocket 24 and a cutting tool 25 installed on the moving plate 23; the bracket 2 is threadedly connected to the cabin 1.

[0039] A spray method for separating copper and tin from tinned copper wire, used to implement the spray device, includes:

[0040] First, according to the specifications of the copper wire to be processed, adjust the position of the worm 21 and worm gear 22 transmission to adapt to copper wires of different sizes. Before the copper wire enters the filter cylinder 51, it is first precisely cut by the wire splitting assembly to expose the tin layer. The servo motor drives the worm 21 to rotate, and through the transmission of the worm gear 22, the grooved pulley 24 and the cutter 25 on the moving plate 23 perform precise cutting actions. The cutter 25 accurately cuts into the surface of the copper wire without damaging the copper core, preparing for subsequent spraying.

[0041] When it is necessary to separate the broken or fractured tinned copper wire, open the cover plate 52 at the feed inlet 11, send the broken or fractured tinned copper wire through the feed inlet 11, and then conduct a preliminary screening to remove larger fragments and other impurities. After screening, spray the copper wire for the first spraying treatment to remove some loose tin layers.

[0042] When it is necessary to separate the complete tinned copper wire, introduce the completely cut tinned copper wire into the filter cylinder 51 through the inlet 3. The inlet 3 allows the copper wire to pass through smoothly and enter the interior of the filter cylinder 51 without prior crushing. When the third hollow shaft 32 needs to separately adjust the position of the pipeline 323 in the box body 312, move the collar 33 to separate it from the first hollow shaft 31, and then rotate the third hollow shaft 32 to drive the third gear 321 to drive the rack 322 to move, causing the pipeline 323 to move. After the adjustment is completed, under the action of the spring 34, the collar 33 moves and the third hollow shaft 32 rotates synchronously with the first hollow shaft 31.

[0043] The drive motor starts, driving the fourth gear 42 and the first gear 313 to rotate, and then causing the second hollow shaft 41 and the first hollow shaft 31 to rotate at the set speeds respectively. The second hollow shaft 41 drives the box body 312 to rotate around the copper wire, enabling the nozzle 324 to contact the copper wire in all directions.

[0044] The spraying liquid is introduced into the first hollow shaft 31 through the rotary joint 311, and then transmitted through the pipeline to the pipeline 323 in the box body 312. The multiple nozzles 324 on the pipeline 323 move along a specific path with the coordinated movement of the rack 322 and the third gear 321, ensuring that the spraying liquid evenly covers the copper wire. During the spraying process, the tin layer is gradually removed and separated from the copper wire, and the separated tin is discharged from the discharge port 12 through the collection system. The discharge port 12 is also responsible for discharging the processed copper wire, ensuring that the clean copper wire can be smoothly removed.
