Description

Technical Field

[0001] This utility model belongs to the field of feeding devices, specifically relating to a copper strip feeding device. 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, it is generally necessary to drive the copper strip and aluminum wire to unwind and feed synchronously so that the copper strip gradually coats the surface of the aluminum wire during the transmission process.

[0004] However, in actual production, existing copper strip feeding equipment uses horizontal unwinding rollers, which means that the copper strip is unwound while the center line of the copper strip is extended horizontally. Under gravity, the copper strip is easily squeezed against each other and friction is generated during traction unwinding. This can easily lead to the copper strip being stretched or even broken, affecting the coating quality. In addition, it increases the power consumption of unwinding and the cost is high. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a brand-new copper strip feeding device.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A copper strip feeding device includes a base, a feeding platform horizontally arranged on the base, a rotary driver, and a guiding assembly. The feeding platform is provided with a vertically extending positioning shaft. A copper strip drum is sleeved on the positioning shaft from the hollow area and supported on the feeding platform. The guiding assembly includes a multi-stage guide roller group arranged in sequence. The rotary driver drives the feeding platform and causes the copper strip drum to rotate around the center line of the positioning shaft. The copper strip then passes forward from the copper strip drum through the multi-stage guide roller group in sequence, and the width direction of the copper strip gradually changes from the vertical direction to the horizontal direction.

[0008] Preferably, the multi-stage guide roller group includes a first guide roller group and a second guide roller group. The copper strip passes through the first guide roller group and the second guide roller group sequentially from the edge of the copper strip drum diagonally forward and upward. 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. This not only simplifies the structure and makes implementation convenient, but also avoids the problem of the copper strip falling to the ground due to slack when the machine is stopped.

[0009] Preferably, the first guide roller group includes a first roller frame disposed above and in front of the material placement platform, and a first guide roller whose two ends are respectively connected to the base and the first roller frame and extend vertically at an inclination; the second guide roller group includes a second guide roller disposed in front of the first roller frame and extending horizontally.

[0010] Specifically, the first roller frame has left and right extending adjustment grooves, and the upper end of the first guide roller is movably connected to 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 drum due to consumption can be flexibly matched.

[0011] Furthermore, there are two first guide rollers arranged symmetrically on the left and right sides, with a V-shaped guide zone formed between the two first guide rollers. This allows for flexible design of the copper strip unwinding from either the left or right edge of the copper strip drum.

[0012] 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.

[0013] Preferably, the feeding assembly further includes a tension roller group connected to the second guide roller group, wherein the tension roller group is used to adjust the surface tension of the copper strip. This ensures the stability of the copper strip's transmission after the width direction changes.

[0014] Specifically, the tension roller assembly includes a third roller frame and tension rollers that are rotatably connected to the third roller frame about a vertical centerline.

[0015] Furthermore, the third roller frame is rotatably connected to the front end of the base and can be tilted up and down for adjustment.

[0016] Furthermore, when the copper strip is wound onto the copper strip spool, 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.

[0017] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] Existing methods use horizontal unwinding rollers, where the copper strip is unwound while maintaining its centerline horizontally. Under gravity, the copper strip is prone to mutual compression and friction during unwinding, which can lead to stretching or even breakage, affecting coating quality. Furthermore, this increases unwinding power consumption and costs. This application, however, features a comprehensive design for the copper strip feeding device, cleverly addressing the shortcomings and defects of existing technologies. With this device, the copper strip drum is vertically mounted on a positioning shaft and supported on a feeding platform. A rotary driver drives the feeding platform, causing the copper strip drum to rotate around the centerline of the positioning shaft. The copper strip then unwinds from the drum and passes forward through multiple guide rollers, with the width of the copper strip gradually changing from vertical to horizontal to supply subsequent aluminum wire coating. Therefore, compared with the prior art, this utility model, on the one hand, is based on the cooperation between the material feeding platform and the multi-stage guide roller group, so that the copper strip drum keeps the center line vertically downward to carry out copper strip unwinding and feeding, which greatly reduces the difficulty of copper strip unwinding, reduces the risk of copper strip deformation and breakage under stress, effectively improves the feeding quality of copper strip, and enhances the coating effect; on the other hand, it has a simple structure, is easy to implement, and has low power consumption, which is conducive to saving costs.

[0032] like Figures 1 to 3 As shown, a copper strip feeding device according to this embodiment includes a base 1, a material placement platform 2 horizontally arranged on the base 1, a rotary driver, and a material guiding assembly 3.

[0033] Specifically, the material placement platform 2 is provided with a vertically extending positioning shaft 20, and the copper strip drum T is sleeved on the positioning shaft 20 from the hollow area and supported on the material placement platform 2; the rotary drive is a conventional motor and is installed on the base 1. The rotary drive drives the material placement platform 2 and causes the copper strip drum T to rotate around the center line of the positioning shaft 20.

[0034] In this example, the material guiding assembly 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 drum, 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 drum and supported on the material placement platform, while adjusting the width direction of the copper strip to match the subsequent wrapping direction.

[0035] In some specific embodiments, when the copper strip is wound on a copper strip spool, 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.

[0036] 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 drum, sequentially through the first guide roller assembly 31 and the second guide roller assembly 32. Here, based on the layout of the first and second guide roller assemblies, the width direction of the copper strip is changed during its upward transmission. This not only simplifies the structure and makes implementation convenient, but also avoids the problem of the copper strip slackening and falling to the ground when the machine stops.

[0037] 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 2, and a first guide roller 312 whose two ends are respectively connected to the base 1 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.

[0038] 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 drum.

[0039] 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 base 1 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 drum caused by consumption can be flexibly matched.

[0040] 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.

[0041] 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.

[0042] In some specific embodiments, the tension roller assembly 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 base and can be tilted up and down for adjustment. The tension roller 332 is located below the second guide roller 321.

[0043] In summary, by adopting this copper strip feeding device, the copper strip drum is vertically mounted on the positioning shaft and supported on the feeding platform while maintaining its centerline. A rotary driver drives the feeding platform, causing the copper strip drum to rotate around the centerline of the positioning shaft. The copper strip then unwinds from the drum and passes sequentially through a multi-stage guide roller assembly. The width direction of the copper strip gradually changes from vertical to horizontal to supply the subsequent aluminum wire coating. Therefore, compared with existing technologies, this invention, firstly, based on the cooperation between the feeding platform and the multi-stage guide roller assembly, ensures that the copper strip drum maintains a vertical centerline during unwinding and feeding, greatly reducing the difficulty of unwinding the copper strip, minimizing the risk of deformation and breakage under stress, effectively improving the quality of copper strip feeding, and enhancing the coating effect; secondly, it has a simple structure, is easy to implement, and has low power consumption, which helps save costs; thirdly, based on the layout of the first and second guide roller assemblies, it achieves a change in the width direction of the copper strip during its upward transmission, which is not only simple in structure and easy to implement, but also avoids... The issues include: firstly, the problem of copper strip falling to the ground due to slack during machine stoppage; secondly, the problem of adjusting the first roller frame left and right to flexibly match the changes in the unwinding position of the copper strip on the drum due to consumption, and the design of unwinding the copper strip from the left or right edge of the drum based on the V-shaped guide zone; thirdly, the problem of adjusting the second guide roller to 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 closely, reducing wrinkles; and fourthly, the problem of using tension roller sets to ensure the stability of transmission after the copper strip width direction changes.

[0044] 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.
