However, this fixed shaft and integrated guide wheel design has significant problems in practical application, as follows:
[0004] Inconsistent tension: due to the inconsistent thickness of the superconducting tape between each lane or the precision error of the processing diameter of each slot, the tension between each lane of superconducting tape is different. This inconsistency in tension can cause the superconducting tape to deform or break during winding, thereby damaging the original superconducting film and causing superconducting performance failure.
[0005] Product damage: due to the large end-dragging force, the superconducting tape is easily pulled apart, causing serious product damage, which not only increases production costs, but also affects product reliability and consistency.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0027] Reference Figure 1 and 2As shown, the utility model discloses a high temperature superconducting tape copper plating spiral winding structure, include: bottom plate 1, roller 2, guide pulley 3 and end cover 4, one end of roller 2 is rotationally arranged on bottom plate 1, guide pulley 3 includes a plurality, and is independently operated in the outside of roller 2, and the other end of roller 2 is provided with end cover 4, and is used for limiting guide pulley 3 installed on roller 2.
[0028] Based on the above structure, the guide pulley 3 can independently rotate freely on the roller 2, and the roller 2 itself also rotates, reducing the friction and resistance between the tape and the guide pulley 3, allowing the tape to move more freely during winding, ensuring that the tension of the tape remains consistent during winding, avoiding deformation or breakage of the superconducting tape due to excessive tension, reducing the risk of product damage, improving the manufacturing quality and reliability of the superconducting tape
[0029] Among them, the guide pulley 3 includes a first guide pulley 31 and a second guide pulley 32, the first guide pulley 31 is nested on the outside of the second guide pulley 32, and the axial and radial contact is formed between the two; The axial contact allows the first guide pulley 31 and the second guide pulley 32 to rotate freely in the axial direction to adapt to the change of the thickness of the superconducting tape or the error of the contact outer diameter of the guide pulley; The radial contact forms a contact surface of 1-2mm between the first guide pulley 31 and the second guide pulley 32. When the superconducting tape runs on the guide pulley 3, since the first guide pulley 31 and the second guide pulley 32 can independently operate, even if the thickness of the superconducting tape is different or the contact outer diameter of the guide pulley 3 has an error, each superconducting tape can adjust the speed itself, so that the tension between each superconducting tape will not differ greatly, and the effect of correcting the slip or tightness of the running tape is corrected, which maximizes the reduction of the problem of unstable slip or too large tension of the superconducting tape in the contact and spiral winding running, so as to ensure that the tension of the superconducting tape is always stable, and the best effect is achieved.
[0030] Specifically, the edges of the first guide pulley 31 and the second guide pulley 32 are each provided with a convex edge 33, which is convexly arranged along the circumferential direction of the first guide pulley 31 and the second guide pulley 32. The convex edge 33 at the edge is designed to protrude along the circumferential direction of the guide pulley 3, which provides a limiting effect for the superconducting tape to prevent the superconducting tape from shifting during operation.
[0031] As Figure 3 As shown, the second guide pulley 32 includes at least two guide pulleys of different diameters, which are arranged in a stepped structure along the axial direction. This design helps to combine the first guide pulley 31 with the second guide pulley 32 to adapt to superconducting tapes of different thicknesses, improving the adaptability and flexibility of the guide pulley 3 to the tape.
[0032] The first guide pulley 31 is sleeved on the outside of the smaller diameter guide pulley of the second guide pulley 32.
[0033] The running diameter and width of the first guide wheel 31 and the second guide wheel 32 are the same, which ensures the smooth transition and continuity of the tape between different guide wheels 3, and reduces the tape tension changes caused by the size difference of the guide wheels 3.
[0034] The first bearing 5 is arranged between the second guide wheel 32 and the roller 2, and the spacer ring 6 is arranged between adjacent first bearings 5. The first bearing 5 provides stable support and accurate positioning for the second guide wheel 32, ensures the accurate position of the guide wheel 3 during high-speed operation or under heavy load, reduces vibration and wear caused by inaccurate positioning; the first bearing 5 can significantly reduce the direct contact friction between the guide wheel and the roller 2, thereby reducing energy consumption and prolonging the service life of the guide wheel 3 and the roller 2; the second guide wheel 32 can rotate freely along the roller 2, which is crucial to maintaining the consistency of the tension of the superconducting tape during winding, because the guide wheel 3 needs to be able to adapt to the changes in the thickness of the tape and any outer diameter error.
[0035] In the embodiment, the second bearing 8 is arranged in the bottom plate 1, the lower side of the bottom plate 1 is provided with a bearing seat 7 for fixing the second bearing 8 on the bottom plate 1, and the other end of the roller 2 is connected with the second bearing 8.
[0036] In addition, the two ends of the roller 2 are provided with threads, one end of the roller 2 is threadedly connected with the end cover 4, and the other end of the roller 2 is threadedly connected with the locking piece 9 after penetrating out of the second bearing 8. This design provides a reliable fixing and adjusting method, facilitates the installation and maintenance of the roller 2, and at the same time enhances the fixing stability of the roller 2, reduces the deviation of the roller caused by vibration or impact.
[0037] The limiting stop ring 21 is arranged on the roller 2 near the position close to the bottom plate 1, which is used to avoid the axial movement or falling off of the first bearing 5. The design of the limiting stop ring 21 improves the positioning accuracy and stability of the first bearing 5, reduces the risk of failure caused by the displacement of the first bearing 5, and ensures the stable operation of the whole system.
[0038] Obviously, the above embodiments are only examples for the purpose of clear illustration, and are not a limitation on the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
