Description

Technical Field

[0001] This utility model relates to the technical field of copper strip winding machines, specifically a copper strip winding machine in which separator paper can be laid between copper strips. Background Technology

[0002] In the field of copper strip processing and manufacturing, copper strip winding machines are key equipment, undertaking the important task of neatly and orderly winding the processed copper strips into coils. Their performance and winding quality directly affect the storage, transportation and use of subsequent copper strip products.

[0003] During the winding process, copper strips are typically wound continuously onto the winding rollers, inevitably leading to direct contact and friction between adjacent strips. While the copper strip surface requires a certain degree of smoothness, this friction generates significant force during continuous winding. This friction easily causes scratches on the copper strip surface. As a metal material with high surface quality requirements, scratches not only severely affect the aesthetics of copper strip and reduce its market competitiveness, but more importantly, the scratched areas may become stress concentration points. During subsequent processing and use, this can easily lead to breakage and deformation of the copper strip, thereby reducing its performance and reliability, and shortening the product's lifespan.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following is combined Figures 1 to 3 This invention describes a copper strip winding machine that can lay separator paper between copper strips according to an embodiment of the present invention.

[0023] A copper strip winding machine that can lay separator paper between copper strips includes a frame 1, wherein the frame 1 is provided with a copper strip winding device 2, a separator paper feeding device 3 and a copper strip roll clamping device 4. The separator paper feeding device 3 is located at the front end of the frame 1. A copper strip conveying device is located directly below the separator paper feeding device 3. The separator paper feeding device 3 is used to convey separator paper, and the copper strip conveying device is used to convey copper strip. The input end of the copper strip winding device 2 is located at the rear end of the separator paper feeding device 3 and the copper strip conveying device. The copper strip winding device 2 is used to wind up the copper strip and separator paper. The copper strip roll clamping device 4 is located directly above the copper strip winding device 2. The copper strip roll clamping device 4 is used to clamp the wound copper strip roll.

[0024] A copper strip conveyor is installed at the front end of the frame 1. Preferably, this is a conventional conveyor with multiple rollers arranged side-by-side. The copper strip conveyor transports the copper strip to the input end of the copper strip winding device 2. A separator paper feeding device 3 is positioned above the copper strip conveyor, allowing the separator paper to be laid on top of the copper strip. When the copper strip winding device 2 begins winding the copper strip, the copper strip pulls the separator paper along with it, ensuring that each layer of copper strip is separated by the separator paper during winding. This prevents the copper strips from sticking together or scratching during winding, effectively guaranteeing the product quality of the copper strip roll.

[0025] The copper strip coil clamping device 4 is located directly above the copper strip winding device 2. During the winding process, the copper strip coil clamping device 4 can clamp the copper strip coil at all times, so that the two sides of the copper strip coil are subjected to uniform and stable force, preventing the copper strip coil from shaking during the winding process, which would result in uneven edges of the copper strip coil after winding.

[0026] The copper strip winding device 2 includes a bending mechanism 21 and a support roller group 22. The input end of the bending mechanism 21 is located at the front end of the frame 1 and is horizontally arranged. The output end of the bending mechanism 21 is located at the rear end of the frame 1 and is bent. The bending mechanism 21 is used to convey the copper strip and the separator paper backward and to clamp and bend the copper strip and the separator paper. The support roller group 22 is located directly above the bending mechanism 21. The support roller group 22 includes multiple support rollers. Both ends of the support rollers are rotatably mounted on the two side walls of the frame 1. The length direction of the support rollers is left-right. The support rollers are used to support the wound copper strip.

[0027] When the copper strip and separator paper enter the bending mechanism 21, the horizontally positioned input end can initially clamp and provide power to convey the copper strip and separator paper to the rear end. During the process of the copper strip and separator paper passing through the bending mechanism 21, the bending mechanism 21 conveys the copper strip and separator paper to the rear end while using its bending output end to guide the copper strip and separator paper to deform according to a predetermined bending trajectory, thereby achieving the initial bending effect.

[0028] As the copper strip and separator paper are continuously bent, the bent copper strip is smoothly pushed to the upper area of ​​the frame 1 by the bending mechanism 21. Multiple support rollers are set at the top of the frame 1. When the bent copper strip is pushed above the support rollers, the surfaces of the multiple support rollers are in contact with the copper strip. The support rollers can evenly distribute the weight of the copper strip, effectively preventing the copper strip from sagging or deforming due to its own weight.

[0029] In addition, the support rollers also guide the copper strip. As the bent copper strip is continuously pushed forward by the bending mechanism 21, the copper strip at the beginning can move towards the rear end under the rotation of the support rollers. When the beginning end of the copper strip comes into contact with the middle end, the copper strip as a whole is in a dynamic winding initiation stage. Under the combined influence of the bending force continuously applied by the bending mechanism 21 and the guidance and constraint brought about by the rotation of the support rollers, the beginning end of the copper strip is subjected to an inward radial force, and then gradually winds inward, thus beginning the winding process.

[0030] The bending mechanism 21 includes an active roller group 23, a drive assembly 24, a driven roller group 25, and a lifting assembly 26; The active roller group 23 is disposed between the driven roller group 25 and the support roller group 22. The active roller group 23 includes multiple active rollers, and the driven roller group 25 includes multiple driven rollers. The movable end of the drive component 24 is connected to the multiple active rollers respectively. The drive component 24 is used to drive the roller shaft in the active roller group 23 to rotate. The movable end of the lifting assembly 26 is connected to a plurality of driven rollers respectively. The lifting assembly 26 is used to drive the driven rollers to move vertically. The gap between the driven roller group 25 and the driving roller group 23 is the bending space of the copper strip. The plurality of driving rollers correspond one-to-one with the plurality of driven rollers and together clamp the copper strip.

[0031] Because existing winding machines typically use a motor and a rotating shaft, starting the motor drives the rotating shaft to rotate, thus completing the winding action. After winding is complete, the rotating shaft and the copper strip wound on it are unloaded together.

[0032] When the copper strip to be wound is thick and hard, a harder rotating shaft and a more powerful motor are required to complete the winding. During the winding process, there is a possibility that the rotating shaft may have insufficient traction force, making it difficult to bend and wind.

[0033] Therefore, in this application, an alternative winding action is achieved through the active bending mechanism 21. The driven roller group 25 is positioned below the active roller group 23. When the lifting assembly 26 is driven, it can drive multiple driven roller groups 25 to move vertically, thereby adjusting the gap between the driven roller groups 25 and the active roller group 23, allowing the active and driven rollers to clamp the copper strip. Next, the driving assembly 24 can drive multiple active rollers to rotate, causing the active and driven rollers to work together to ensure that the copper strip is smoothly and steadily conveyed to the rear end of the bending mechanism 21.

[0034] Because the output end of the bending mechanism 21 is bent, the clamping force of the driving roller and the driven roller ensures that the copper strip moves along a predetermined trajectory during the bending process, avoiding deviation or twisting. In addition, the lifting assembly 26 can adjust the position of the driven roller according to the thickness and degree of bending of the copper strip to prevent the copper strip from deforming due to excessive clamping force.

[0035] With the bending mechanism 21, the winding machine of this invention can complete the winding process without the need for a high-power motor and a rigid rotating shaft, effectively reducing the difficulty of winding copper strip. Furthermore, the bending mechanism 21 also includes a lifting assembly 26, which can adjust the height of the driven roller group 25, allowing the winding machine of this invention to flexibly adjust the spacing between the rollers according to the thickness of the copper strip and paper, thus broadening its application.

[0036] In addition, when the copper strip coil is unloaded, it can be transferred to the next station by a crane, which effectively avoids the problem of low production efficiency caused by the need to reinstall the rotating shaft after unloading the traditional winding machine.

[0037] Each of the multiple lifting components 26 corresponds to one of the multiple driven rollers; each lifting component 26 includes a lifting sliding seat 261 and a lifting power component 262. Vertical lifting sliding holes 260 are provided on both the left and right side walls of the frame 1. The left and right ends of the lifting sliding seat 261 are slidably connected to the corresponding lifting sliding holes 260. The mounting end of the lifting power component 262 is located at the bottom of the frame 1. The movable end of the lifting power component 262 is fixedly connected to the lifting sliding seat 261. The lifting power component 262 is used to drive the lifting sliding seat 261 to move vertically. The left and right ends of the driven roller are respectively rotatably connected to the lifting sliding seat 261.

[0038] The lifting slide hole 260 provides a guide for the lifting slide seat 261, effectively preventing the lifting slide seat 261 from shaking or shifting during the lifting process, ensuring the stability and accuracy of the driven roller group 25 lifting, and thus precisely controlling the bending degree of the copper strip.

[0039] The left and right ends of the driven roller are rotatably connected to the lifting slide seat 261. When the lifting slide seat 261 moves in the vertical direction, the driven roller can rise and fall smoothly and remain stable during rotation, reducing copper strip damage or winding quality problems caused by unstable operation of the driven roller.

[0040] In this embodiment, the lifting power component 262 is preferably a cylinder. Multiple lifting components 26 correspond one-to-one with multiple driven rollers, ensuring that operators can adjust specific driven rollers, greatly improving operational flexibility.

[0041] The drive assembly 24 is provided between every two driven rollers. The drive assembly 24 includes a drive power component 241, a drive gear 242, and a driven gear 243. The drive power component is mounted on the frame 1, and the output end of the drive power component 241 is fixedly sleeved with the drive gear 242; The left and right ends of the drive roller are rotatably connected to the two side walls of the frame 1, respectively. A driven gear 243 is fixedly sleeved on the end of the drive roller near the drive power component 241. The drive gear 242 meshes with two adjacent driven gears 243.

[0042] Since a drive assembly 24 is set between every two driven rollers, when the drive power component 241 is started, the drive power component 241 drives the drive gear 242 to rotate, the drive gear 242 drives the two adjacent driven gears 243 to rotate, and the driven gears 243 drive the corresponding drive roller to rotate, thereby achieving the effect of the drive roller rotating and conveying the copper strip backward.

[0043] Furthermore, the drive unit 241 is preferably an electrode. Operators can adjust the rotational speed of the drive unit 241 according to the tension of the copper strip to ensure that the adjusted rotational speed of the drive roller meets the tension requirements.

[0044] The curved space includes a flat section, a transition section, and a curved section from front to back; the inclination angle of the curved section is greater than that of the transition section, and the inclination angle of the transition section is greater than that of the flat section.

[0045] Dividing the bending space into a smooth section, a transition section, and a bending section, with the inclination angle increasing sequentially, this design conforms to the physical characteristics of copper strip gradually bending from a straight state. The smooth section provides a smooth initial transition for the copper strip entering the bending area, avoiding stress concentration caused by sudden large-angle bending and reducing the risk of defects such as wrinkles and breakage. The transition section further guides the copper strip to adapt to the change in bending angle, allowing it to smoothly transition from a smooth state to a bent state. The larger inclination angle of the bending section ensures that the copper strip reaches the required degree of bending, meeting winding requirements. The entire process is gradual, improving the quality and stability of copper strip bending.

[0046] The active roller group 23 includes a first active roller 231, a second active roller 232, a third active roller 233, and a fourth active roller 234; the driven roller group 25 includes a first driven roller 251, a second driven roller 252, a third driven roller 253, and a fourth driven roller 254. The first driving roller 231, the second driving roller 232, the first driven roller 251 and the second driven roller 252 form a gentle section; the second driving roller 232, the third driving roller 233, the second driving roller 232 and the third driven roller 253 form an inclined section; the third driving roller 233, the fourth driving roller 234, the third driven roller 253 and the fourth driven roller 254 form a curved section.

[0047] The smooth section is formed by the first driving roller 231, the second driving roller 232, the first driven roller 251, and the second driven roller 252. This combination allows the copper strip to transition smoothly before entering the bending area, reducing stress concentration caused by sudden force and preventing defects such as wrinkles and scratches. The inclined section is formed by the second driving roller 232, the third driving roller 233, the second driven roller 252, and the third driven roller 253, providing a reasonable transition for the copper strip from the smooth state to the bending state. This allows the copper strip to gradually adapt to changes in the bending angle, further reducing uneven stress and the risk of damage during the bending process. The bending section is formed by the third driving roller 233, the fourth driving roller 234, the third driven roller 253, and the fourth driven roller 254, ensuring that the copper strip reaches the required degree of bending and is wound tightly and neatly.

[0048] The copper strip coil clamping device 4 is provided on both the left and right sides of the frame 1. The copper strip coil clamping device 4 includes a clamping plate 41, a clamping power component 42, and a clamping guide rod 43. The clamping power component 42 is installed on the top of the frame 1. The movable end of the clamping power component 42 is fixedly connected to the clamping plate 41. The mounting end of the clamping guide rod 43 is fixedly connected to the clamping plate 41. The movable end of the clamping guide rod 43 is slidably connected to the side wall of the frame 1. The length direction of the clamping guide rod 43 and the movement direction of the clamping power component 42 are both horizontal.

[0049] It is worth noting that the clamping power component 42 is preferably a cylinder. When the clamping power components 42 located on both sides of the frame 1 are activated, the clamping power components 42 push the clamping plates 41 into the interior of the frame 1, so that the two clamping plates 41 come closer to each other, thereby achieving the effect of clamping the copper strip coil and preventing the copper strip coil from shaking or shifting when rotating at high speed or subjected to external force.

[0050] The clamping guide rod 43 provides precise guidance for the movement of the clamping plate 41, enabling the clamping plate 41 to move smoothly and accurately in the horizontal direction during the clamping process. This avoids problems such as offset or tilting of the clamping plate 41 during the movement, ensuring the reliability and stability of the clamping action and improving the accuracy of equipment operation.

[0051] The clamping plate 41 has a receiving hole and a clamping roller 44. The two ends of the clamping roller 44 are rotatably connected to the two opposite holes of the receiving hole.

[0052] A rotatable clamping roller 44 is provided on the clamping plate 41. When the clamping plate 41 clamps the copper strip coil, the clamping roller 44 contacts the surface of the copper strip coil and rolls as the copper strip coil rotates. Compared with the clamping plate 41 directly contacting the surface of the copper strip coil, the rolling contact method of the clamping roller 44 greatly reduces the friction between the two, avoiding problems such as scratches and wear on the surface of the copper strip coil caused by friction, and ensuring the appearance quality and performance of the copper strip coil.

[0053] The clamping roller 44 is inclined from top to bottom toward the center of the clamping plate 41.

[0054] When winding copper strip coils of different diameters, the inclined clamping rollers 44 can better adapt to changes in the shape of the copper strip coils. For copper strip coils of different diameters, the inclination angle of the clamping rollers 44 can abut against the surface of the copper strip coil, providing sufficient clamping force. This allows the copper strip winding machine of this application to meet the winding requirements of copper strip coils of various specifications, improving the versatility of the equipment.

[0055] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
