Abstract
Description
Technical Field
[0001] This utility model belongs to the field of copper-clad aluminum technology, specifically relating to an integrated device for continuous copper strip feeding and surface treatment. Background Technology
[0002] Copper-clad aluminum wire refers to an electrical wire with an aluminum core and an outer layer of copper. It can be used as a conductor in coaxial cables and electrical equipment cables. Aluminum wire has a low specific gravity, but its welding performance is poor. Therefore, a copper layer is clad around the aluminum wire. This type of copper-clad aluminum wire utilizes the advantage of aluminum's low specific gravity and also improves its welding performance.
[0003] Currently, in the production of copper-clad aluminum wire, the copper strip and aluminum core wire are unwound and fed simultaneously to gradually drive the copper strip to cover the surface of the aluminum core wire during the transmission process. The copper strip is mainly unwound and transported using horizontal unwinding rollers. That is, the copper strip is rolled onto the unwinding rollers and unwound as the unwinding rollers rotate. At the same time, in order to avoid the formation of an oxide layer on the surface of the copper strip, which would affect the conductivity of the copper-clad aluminum wire, the oxide layer on the surface of the copper strip needs to be ground off with a brush after unwinding.
[0004] However, in actual production processes, existing technologies are prone to the following drawbacks:
[0005] 1. Copper strips are easily squeezed together under gravity and generate friction during traction unwinding, which may cause the copper strips to be stretched or even break, affecting the coating quality. In addition, it increases unwinding power consumption and costs.
[0006] 2. During transmission, the copper strip is subjected to the squeezing effect of the guide roller, which easily causes surface deformation and makes it impossible to maintain flatness. Therefore, when the copper strip passes through the grinding area formed by the brush cylinder, some areas are easily over-grinded and some areas have incomplete oxide layer removal, resulting in a low product yield. Summary of the Invention
[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved integrated device for continuous copper strip feeding and surface treatment.
[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0009] An integrated device for continuous feeding and surface treatment of copper strip includes an unwinding unit and a grinding unit. The unwinding unit includes an unwinding frame, an unwinding power unit, and a material guiding assembly. The copper strip roll is vertically positioned on the unwinding frame with its center line maintained. The unwinding power unit drives the copper strip roll to rotate around the vertical center line to drive the copper strip to unwind and be transported forward. The material guiding assembly is set on the transport path of the copper strip and drives the width direction of the copper strip to change from the vertical direction to the horizontal direction. The integrated device also includes a shaping unit set between the unwinding unit and the grinding unit. The shaping unit forms a shaping channel that extends horizontally. The copper strip passes through the shaping channel horizontally, and the upper and lower walls of the shaping channel are simultaneously pressed and driven to keep the upper and lower surfaces of the copper strip flat.
[0010] Preferably, the shaping unit includes an upper shaping mold and a lower shaping mold, and an adjusting component for driving the upper and lower shaping molds to press or release against each other, wherein a shaping channel is formed between the upper and lower shaping molds. This design is simple and easy to adjust.
[0011] Preferably, cushioning pads are laid flat on the lower surface of the upper forming mold and the upper surface of the lower forming mold. This is to prevent damage to the surface of the copper strip.
[0012] Specifically, the lower forming mold has multiple guide pillars, and the upper forming mold is slidably connected to these guide pillars. The adjusting components include a fixed base fixed to the guide pillars and located above the upper forming mold, and a bolt adjusting component that passes through the fixed base from top to bottom and forms a threaded engagement, wherein the lower end of the bolt adjusting component abuts against the upper forming mold. This facilitates precise adjustment of the forming pressure applied to the surface of the copper strip.
[0013] Preferably, the grinding unit includes multiple grinding wheels arranged sequentially along the copper strip conveying direction, multiple limiting seats correspondingly disposed below the grinding wheels, and waste discharge grooves disposed below the limiting seats. Each limiting seat has a limiting groove that extends through the front and rear and can limit the copper strip in the left and right directions. The copper strip is conveyed horizontally and passes through each limiting groove sequentially, and the multiple grinding wheels grind the upper surface of the copper strip in stages. Here, multi-stage grinding is performed on the surface of the copper strip to improve the removal rate of the surface oxide layer; at the same time, based on the layout of the limiting grooves, the copper strip is prevented from shifting under force.
[0014] Preferably, the integrated device further includes a wiping component disposed between the unwinding unit and the forming unit for wiping the surface of the copper strip. Here, the wiping component removes large-diameter particulate impurities from the surface of the copper strip beforehand to avoid damage to the copper strip during forming.
[0015] Preferably, the unwinding frame includes a frame base and a material placement platform horizontally arranged on the frame base, wherein the material placement platform has a vertically extending central shaft, and the copper strip coil is sleeved onto the central shaft from the hollow area and supported on the material placement platform. This facilitates rapid positioning.
[0016] Preferably, the material guiding assembly includes a first guide roller group, a second guide roller group, and a tension roller group arranged sequentially from front to back, wherein the copper strip passes diagonally forward and upward from the edge of the copper strip roll through the first guide roller group and the second guide roller group. Here, based on the layout of the first and second guide roller groups, the width direction of the copper strip is changed during the bottom-up transmission, which not only has a simple structure and is easy to implement, but also avoids the problem of the copper strip falling to the ground due to slack when the machine stops.
[0017] Specifically, the first guide roller group includes a first roller frame disposed above the front of the material placement platform, and a first guide roller whose two ends are respectively connected to the frame and the first roller frame and extend vertically at an incline; the second guide roller group includes a second guide roller disposed in front of the first roller frame and extending horizontally.
[0018] Preferably, there are two first guide rollers arranged symmetrically from left to right, with a V-shaped guiding zone formed between the two first guide rollers; the first roller frame also has left-right extending adjustment grooves, and the upper ends of the two first guide rollers are movably connected in the adjustment grooves and can be adjusted left and right. Here, by adjusting the first roller frame left and right, the unwinding position of the copper strip on the copper strip coil can be flexibly matched to the changes caused by the consumption of the copper strip, and the design of unwinding the copper strip from the left or right edge of the copper strip coil can be flexibly applied.
[0019] Preferably, the second guide roller assembly further includes a second roller frame that is slidably connected to the first roller frame, and the second guide roller is rotatably connected to the second roller frame about a vertical centerline. Here, by rotating and adjusting the second guide roller, it is possible to precisely match the change in angle of the copper strip after it passes through the first guide roller, ensuring that the copper strip passes over the surface of the second guide roller in a relatively close manner, reducing the occurrence of wrinkles.
[0020] In addition, the tension roller assembly includes a third roller frame that is rotatably connected to the front end of the frame and can be adjusted by flipping up and down, and a tension roller that is rotatably connected to the third roller frame about the vertical centerline and is used to adjust the surface tension of the copper strip.
[0021] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:
[0022] Existing copper strips are prone to mutual compression under gravity and friction during traction unwinding, which can lead to tension or even breakage of the copper strip, affecting the coating quality. In addition, it increases unwinding power consumption and costs. At the same time, the copper strip is affected by the compression of the guide rollers during transmission, and the surface is prone to deformation, making it impossible to maintain flatness. Therefore, when the copper strip passes through the grinding area formed by the brush cylinder, some areas are prone to over-grinding and some areas have incomplete oxide layer removal, resulting in low product yield. This application presents an integrated design for a continuous copper strip feeding and surface treatment device, cleverly addressing the shortcomings and defects of existing technologies. With this integrated device, the copper strip coil is vertically positioned on the unwinding frame, and a rewinding power unit drives the coil to rotate around the vertical centerline. The copper strip then unwinds from the coil and passes forward through the guide assembly, which drives the width direction of the copper strip to gradually change from vertical to horizontal. Next, the copper strip passes horizontally through the forming channel, where the upper and lower walls simultaneously press and drive the upper and lower surfaces of the copper strip to remain flat. Finally, the surface-formed copper strip is transferred to the grinding unit to remove the surface oxide layer, supplying subsequent aluminum wire coating. Therefore, compared with the prior art, this utility model, on the one hand, reduces the difficulty of copper strip unwinding and feeding by keeping the center line of the copper strip coil vertical, reduces the risk of copper strip deformation and breakage under stress, and effectively improves the feeding quality of copper strip; on the other hand, by setting a shaping channel to keep the surface of the copper strip flat, it ensures that the surface of the copper strip is ground comprehensively and evenly, improves the oxide layer removal rate, and improves the product yield; in addition, the structure is simple, easy to implement, and has low power consumption, which helps to save costs.

[0038] like Figures 1 to 5 As shown in the figure, this embodiment of a copper strip continuous feeding and surface treatment integrated device includes an unwinding unit A, a shaping unit B, and a grinding unit C.
[0039] Specifically, the unwinding unit A includes an unwinding frame 1, an unwinding power unit 2, and a material guiding assembly 3. The copper strip is positioned vertically on the unwinding frame 1 with its center line maintained. The unwinding power unit 2 drives the copper strip to rotate around the vertical center line to drive the copper strip T to unwind and be transported forward. The material guiding assembly 3 is set on the transport path of the copper strip T and drives the width direction of the copper strip T to change from the vertical direction to the horizontal direction.
[0040] The unwinding frame 1 includes a frame base 10 and a material placement platform 11 horizontally arranged on the frame base 10. The material placement platform 11 is provided with a vertically extending central shaft s. The copper strip coil is sleeved on the central shaft s from the hollow area and supported on the material placement platform 11. This facilitates rapid positioning.
[0041] The unwinding power unit 2 is a conventional motor and is mounted on the frame 10. It drives the material feeding platform 11 and causes the copper strip to rotate around the center line of the central shaft s.
[0042] In this example, the material guiding component 3 includes a multi-stage guide roller group arranged in sequence. The copper strip passes through the multi-stage guide roller group in sequence from the copper strip roll, and the width direction of the copper strip gradually changes from the vertical direction to the horizontal direction, so as to realize the unwinding based on the vertical center line of the copper strip roll and supported on the material placement platform, while adjusting the width direction of the copper strip to match the subsequent wrapping direction.
[0043] In some specific embodiments, when the copper strip is wound on a copper strip roll, the copper strip forms a covering surface from the inside, and when the width direction of the copper strip changes to the left-right direction, the copper strip is transported with the covering surface facing upwards.
[0044] The multi-stage guide roller assembly includes a first guide roller assembly 31 and a second guide roller assembly 32. The copper strip passes diagonally forward and upward from the edge of the copper strip coil through the first guide roller assembly 31 and the second guide roller assembly 32 in sequence. Here, based on the layout of the first and second guide roller assemblies, the width direction of the copper strip is changed during the upward transmission. This not only simplifies the structure and makes implementation convenient, but also avoids the problem of the copper strip loosening and falling to the ground when the machine stops.
[0045] In some specific embodiments, the first guide roller group 31 includes a first roller frame 311 disposed above the front of the material placement platform 11, and a first guide roller 312 whose two ends are respectively connected to the frame 10 and the first roller frame 311 and extend vertically at an incline; the second guide roller group 32 includes a second guide roller 321 disposed in front of the first roller frame 311 and extending horizontally, and a second roller frame 322.
[0046] For ease of implementation, there are two first guide rollers 312 arranged symmetrically on the left and right, with a V-shaped material guiding zone formed between the two first guide rollers 312. This allows for flexible design of the copper strip unwinding from either the left or right edge of the copper strip coil.
[0047] Meanwhile, the first roller frame 311 has left-right extending adjustment grooves c. The upper end of each first guide roller 312 is movably connected in the adjustment groove c and can be adjusted left and right, while the lower end is rotatably connected to the frame 10 via a pivot (not shown in the figure, but it is not difficult to imagine). Here, by adjusting the first roller frame left and right, the unwinding position of the copper strip on the copper strip coil can be flexibly matched to the changes caused by the consumption of the copper strip.
[0048] To further facilitate implementation, the second roller frame 322 is slidably connected to the first roller frame 311, and the second guide roller 321 is rotatably connected to the second roller frame 322 around the vertical centerline. Here, the second guide roller is adjusted by rotation to precisely match the change in angle after the copper strip passes through the first guide roller, ensuring that the copper strip passes over the surface of the second guide roller in a relatively close manner, reducing the occurrence of wrinkles.
[0049] Furthermore, the material guiding assembly 3 in this embodiment also includes a tension roller group 33 connected to the second guide roller group 32, wherein the tension roller group 33 is used to adjust the surface tension of the copper strip. This ensures the stability of the transmission after the copper strip width direction changes.
[0050] In some specific embodiments, the tension roller group 33 includes a third roller frame 331 and a tension roller 332 rotatably connected to the third roller frame 331 about a vertical centerline. The third roller frame 331 is rotatably connected to the front end of the frame and can be tilted up and down for adjustment. The tension roller 332 is located below the second guide roller 321.
[0051] In this example, the shaping unit B is located between the unwinding unit A and the grinding unit C. The shaping unit B forms a shaping channel t that extends forward and backward. The copper strip passes through the shaping channel t horizontally, and the upper and lower walls of the shaping channel t are pressed together synchronously to keep the upper and lower surfaces of the copper strip flat.
[0052] In some specific embodiments, the shaping unit B includes an upper shaping mold 4 and a lower shaping mold 5, and an adjusting component 6 for driving the upper shaping mold 4 and the lower shaping mold 5 to press or loosen against each other. A shaping channel t is formed between the upper shaping mold 4 and the lower shaping mold 5. Buffer pads d are respectively laid flat on the lower surface of the upper shaping mold 4 and the upper surface of the lower shaping mold 5, and an oil film layer is provided between the buffer pads d to reduce the resistance of the copper strip transmission. This prevents damage to the surface of the copper strip.
[0053] Meanwhile, the lower forming mold 5 is provided with multiple guide pillars z, and the upper forming mold 4 is slidably connected to the multiple guide pillars z. The adjusting component 6 includes a fixed seat 60 fixed on the multiple guide pillars z and located above the upper forming mold 4, and a bolt adjusting component 61 that passes through the fixed seat 60 from top to bottom and forms a threaded engagement, wherein the lower end of the bolt adjusting component 61 abuts against the upper forming mold 4. This facilitates precise adjustment of the forming pressure applied to the surface of the copper strip.
[0054] To further facilitate implementation, the integrated device in this embodiment also includes a wiping component D disposed between the unwinding unit A and the shaping unit B for wiping the surface of the copper strip. The wiping component D can be a flexible wiping cloth covering the surface of the copper strip. Here, large-diameter particulate impurities on the surface of the copper strip are removed by the wiping component before grinding to avoid damage to the copper strip during shaping.
[0055] Furthermore, the grinding unit C includes multiple grinding wheels 7 arranged sequentially along the copper strip conveying direction, multiple limiting seats 8 correspondingly arranged below the multiple grinding wheels 7, and waste discharge grooves 9 arranged below the multiple limiting seats 8. Each limiting seat 8 has a limiting groove 80 that runs through the front and back and can limit the copper strip in the left and right directions. The copper strip is conveyed horizontally and passes through each of the limiting grooves 80 in sequence, and the multiple grinding wheels 7 grind the upper surface of the copper strip in stages. The waste discharge groove 9 is an arc shape that arches downwards, and the waste generated by grinding accumulates at the bottom of the waste discharge groove 9 along the inner wall of the arc. Here, multi-stage grinding is performed on the surface of the copper strip to improve the removal rate of the surface oxide layer; at the same time, based on the layout of the limiting grooves, the copper strip is prevented from being deflected by force.
[0056] In summary, by adopting this integrated device, the copper strip coil is positioned vertically on the unwinding frame with its center line kept upright. The unwinding power unit drives the copper strip coil to rotate around the vertical center line, and the copper strip is unwound from the copper strip coil and passes forward through the guide assembly. The guide assembly drives the width direction of the copper strip to gradually change from the vertical direction to the horizontal direction. Then, the copper strip passes horizontally through the shaping channel, where the upper and lower walls of the shaping channel simultaneously press and drive the upper and lower surfaces of the copper strip to keep them flat. Finally, the copper strip with the surface shaped is transferred to the grinding unit to remove the surface oxide layer in order to supply the subsequent aluminum wire coating. Therefore, compared with existing technologies, this utility model, on the one hand, reduces the difficulty of copper strip unwinding and feeding by keeping the center line of the copper strip coil vertical, thereby reducing the risk of copper strip deformation and breakage under stress and effectively improving the feeding quality of copper strip; on the other hand, by setting a shaping channel to keep the copper strip surface flat, it ensures that the copper strip surface is ground comprehensively and evenly, improving the oxide layer removal rate and increasing the product yield; in addition, the structure is simple, easy to implement, and has low power consumption, which helps to save costs; thirdly, based on the layout of the first and second guide roller groups, the width direction of the copper strip is changed during the bottom-up transmission, which not only improves the structure It is simple and easy to implement, and can avoid the problem of copper strip falling to the ground due to slack when the machine stops; thirdly, by adjusting the first roller frame left and right, it can flexibly match the changes in the unwinding position of the copper strip on the copper strip coil due to consumption, and based on the V-shaped guide zone, it can flexibly adapt to the design of copper strip unwinding from the left or right edge of the copper strip coil; fourthly, by rotating and adjusting the second guide roller, it can accurately match the change in angle of the copper strip after passing through the first guide roller, ensuring that the copper strip passes over the surface of the second guide roller relatively close to the surface, reducing the occurrence of wrinkles; fifthly, a tension roller group is used to ensure the stability of transmission after the copper strip width direction changes.
[0057] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
