Description

Technical Field

[0001] This utility model relates to the field of take-up and take-down devices, and in particular to a take-up and take-down device for superconducting tape. Background Technology

[0002] In the field of superconducting tape production, kilometer-scale tape winding is a crucial step. Current winding technology has significant shortcomings, with uneven tape tension frequently occurring during the winding process. When tension is uneven, the tape edge misalignment often exceeds 1mm. This edge misalignment problem has many adverse consequences. In subsequent welding processes, it is necessary to additionally trim the misaligned portion of the tape, resulting in a 5% - 10% material waste. Moreover, edge misalignment also affects the consistency of interlayer insulation in the tape, thereby adversely impacting the overall performance and quality of the superconducting tape.

[0003] To address the aforementioned problems, this utility model document proposes a device for taking in and releasing superconducting tapes. Utility Model Content

[0004] This invention provides a device for winding and unwinding superconducting tape, which solves the shortcomings of the prior art, such as uneven tension during winding leading to tape edge misalignment, material waste, and inconsistent interlayer insulation.

[0005] This utility model provides the following technical solution:

[0006] A device for storing and taking in superconducting tapes, comprising:

[0007] A vertical plate, on one side of which a unwinding roller, two staggered guide rollers and a take-up roller are rotatably mounted from left to right via bearings. A cylindrical tension sensor is provided below the two guide rollers, and one end of the cylindrical tension sensor is mounted on the side wall of the vertical plate.

[0008] A horizontal plate is provided directly above the take-up roller. One end of the horizontal plate is fixedly connected to the side wall of the vertical plate. A mounting box with vertically adjustable position is provided below the horizontal plate. The same bidirectional threaded screw is rotatably mounted on both ends of the inner wall of the mounting box through bearings.

[0009] In one possible design, a servo motor is fixedly mounted on the other side of the vertical plate, and the output shaft of the servo motor passes through the outer wall of the vertical plate and is fixedly connected to one end of the take-up roller via a coupling.

[0010] In one possible design, a fixed base is fixedly installed on the top of the vertical plate, and a servo driver for adjusting the PID is snapped into the cavity at the top of the fixed base. The input end of the servo driver is connected to the cylindrical tension sensor via a signal line for communication transmission, and the output end of the servo driver is connected to the servo motor via a signal line for communication transmission.

[0011] In one possible design, a threaded rod is threaded into the threaded hole in the center of the horizontal plate. The bottom end of the threaded rod extends through the hole and is rotatably connected to the center of the top of the mounting box via a bearing. The top end of the threaded rod extends through the hole and is fixedly fitted with a handle. Two vertical rods are symmetrically fixedly fitted on the top of the mounting box to prevent it from rotating. The top ends of the vertical rods slide through corresponding sliding holes in the horizontal plate. A fastening nut I is threaded onto the threaded rod, and the bottom of the fastening nut I abuts against the top of the horizontal plate.

[0012] In one possible design, the bidirectional threaded lead screw is symmetrically threaded with two matching lead screw seats. The bottom end of the lead screw seat passes through the opening at the bottom of the mounting box and is fixedly provided with a limiting vertical piece. A sliding piece for improving its movement stability is fixedly provided on one side of the lead screw seat. The mounting box is provided with a strip-shaped sliding hole for sliding connection of the corresponding sliding piece. One end of the bidirectional threaded lead screw passes through the outside of the mounting box and is fixedly connected with a hand-tightening bolt. A fastening nut II is threadedly connected to the hand-tightening bolt, and one side of the fastening nut II abuts against the outer wall of the mounting box.

[0013] In one possible design, two base plates are symmetrically fixed at the bottom of the vertical plate, and two casters are symmetrically installed at the bottom of the base plates.

[0014] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0015] The working principle and usage process of this technical solution are as follows:

[0016] Place the superconducting tape that needs to be rewound on the unwinding roller, and then pass it sequentially around one of the guide rollers, the cylindrical tension sensor, and the other guide roller before finally winding it onto the winding roller. Then, based on the tape width and other factors during the actual winding process, adjust the winding position of the tape to a limiting position. Rotating the handle drives the threaded rod to rotate. Because the threaded rod is threaded into the threaded hole in the center of the horizontal plate, and a vertical rod at the top of the mounting box restricts its rotation, rotating the threaded rod will cause the mounting box to move vertically. After adjusting to the appropriate position, tighten the fastening nut I. First, fix the position of the mounting box, then rotate the hand-tightening bolt to drive the double-threaded screw to rotate. The two screw seats on the double-threaded screw will move relative to each other or towards each other along the double-threaded screw. The limiting vertical piece at the bottom of the screw seat will move accordingly, thereby adjusting the distance between the two limiting vertical pieces to accommodate strips of different widths and limit the winding of the strip. At the same time, the sliding piece on one side of the screw seat slides in the strip-shaped sliding hole of the mounting box to ensure the stability of the movement of the screw seat. After adjusting to the appropriate position, tighten the fastening nut II to fix the position of the double-threaded screw.

[0017] After the servo motor is started, its output shaft drives the winding roller to rotate through the coupling, realizing the winding of the strip. The cylindrical tension sensor monitors the tension of the strip in real time and transmits the tension signal to the servo driver through the signal line. The servo driver analyzes the tension data based on the signal from the cylindrical tension sensor and the PID algorithm: if the tension in the detected area is greater than the set value, the servo motor speed is reduced to reduce the stretching of the strip in that area; if the tension is less than the set value, the speed is increased to compensate for slack. The control signal output to the servo motor is adjusted in real time to regulate the speed of the servo motor, thereby ensuring that the tension of the strip is uniform during the winding process and avoiding misalignment of the strip edges due to uneven tension.

[0018] This utility model has the following beneficial effects:

[0019] This invention uses a cylindrical tension sensor to detect the strip tension in real time, and a servo driver uses a PID control algorithm to control the speed of the servo motor. This solves the problem of strip edge misalignment caused by uneven tension during the winding process, avoids the need for additional strip cutting in subsequent welding processes due to edge misalignment, reduces material waste, and helps ensure the consistency of insulation between strip layers, thereby improving the overall performance and quality of the superconducting strip.

[0020] This utility model, through the combined use of threaded rods, bidirectional threaded screws, and other structures, can easily adjust the vertical position of the mounting box and the distance between the two limiting vertical plates, thereby adapting to the winding and limiting requirements of strips of different widths and improving the versatility and flexibility of the device.

[0021] The bottom plate and casters at the bottom of the vertical plate in this invention allow the entire retraction device to be moved easily, making it convenient to be used in different production sites or processes. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] In one embodiment:

[0031] Please refer to Figure 1-4 A retraction device, comprising:

[0032] A superconducting tape winding and unwinding device includes a vertical plate 1. On one side of the vertical plate 1, an unwinding roller 2, two misaligned guide rollers 3, and a winding roller 4 are rotatably mounted from left to right via bearings. The unwinding roller 2 is used to hold the superconducting tape to be rewound, and the winding roller 4 is used to wind the wound tape. Both the unwinding roller 2 and the winding roller 4 are expansion rollers. The expansion rollers usually have an expandable structure inside, which can be expanded by filling with gas (such as air) or injecting liquid (such as hydraulic oil). By carefully fitting the superconducting tape core onto the appropriately sized unwinding roller 2 and winding roller 4, and then fine-tuning the expansion rollers through an air-filling or liquid-filling device, the pressure inside the expansion rollers is appropriately increased, causing them to expand further. This allows the outer surface of the expansion rollers to tightly adhere to the inner wall of the core, generating sufficient friction.

[0033] The same cylindrical tension sensor 6 is installed below the two guide rollers 3. One end of the cylindrical tension sensor 6 is fixedly installed on the side wall of the vertical plate 1. The cylindrical tension sensor 6 monitors the tension change of the strip in real time during the unwinding and winding process, and converts the tension signal into an electrical signal (such as a voltage or current signal). Based on the strain effect, it senses the elastic deformation caused by the tension of the strip through a metal foil or semiconductor strain gauge. The change in resistance value is converted into a differential voltage signal through a Wheatstone bridge, and outputs an electrical signal that is linearly related to the tension.

[0034] A fixed base 7 is fixedly installed at the top of the vertical plate 1. A servo driver 8 for adjusting the PID is snapped into the cavity at the top of the fixed base 7. The input end of the servo driver 8 is connected to the cylindrical tension sensor 6 via a signal line for communication transmission, and the output end is connected to the servo motor 5 via a signal line for communication transmission transmission. During the winding process, the servo driver 8 receives the signal from the tension sensor 6 and the instructions from the upper controller. It adjusts the output of the servo motor 5 through a closed-loop control algorithm to achieve constant tension. It filters and amplifies the signal from the tension sensor 6 to eliminate noise interference, and uses PID (proportional-integral-derivative) control to calculate the error between the actual tension value and the target value, generates adjustment instructions, and finally controls the IGBT module through PWM (pulse width modulation) to output three-phase AC power to drive the servo motor 5, adjusting the torque and speed. If the tension in a certain area is detected to be greater than the set value (e.g., ±0.5N), the speed of the servo motor 5 is reduced to reduce the stretching of the strip in that area; if the tension is less than the set value, the speed is increased to compensate for slack. The control signal output to the servo motor 5 is adjusted in real time to adjust the speed of the servo motor 5, thereby ensuring uniform tension of the strip during the winding process.

[0035] A servo motor 5 is fixedly installed on the other side of the vertical plate 1. The output shaft of the servo motor 5 passes through the outer wall of the vertical plate 1 and is fixedly connected to one end of the winding roller 4 through a coupling. The servo motor 5 acts as an actuator, adjusting the speed and torque according to the instructions of the servo driver 8 to drive the winding roller 4 to rotate and realize the winding action of the strip. When running, the internal stator winding is energized with alternating current to generate a rotating magnetic field, which interacts with the rotor permanent magnet to generate torque. The built-in encoder detects the rotor position and speed in real time and feeds back to the servo driver 8 to form a closed-loop control.

[0036] A horizontal plate 9 is installed directly above the winding roller 4. One end of the horizontal plate 9 is fixedly connected to the side wall of the vertical plate 1. A vertically adjustable mounting box 10 is installed below the horizontal plate 9. The same bidirectional threaded rod 15 is rotatably mounted on both ends of the inner wall of the mounting box 10 via bearings. A threaded rod 11 is threaded into the threaded hole in the center of the horizontal plate 9. The bottom end of the threaded rod 11 extends through the hole and is rotatably connected to the top center of the mounting box 10 via a bearing. The top end of the threaded rod 11 extends through the hole and is fixedly mounted with a handle 12. Two vertical rods 14 are symmetrically fixedly mounted on the top of the mounting box 10. The top ends of the vertical rods 14 slide through the hole. The corresponding sliding hole on the horizontal plate 9 is connected to the threaded rod 11 with a fastening nut I13. The bottom of the fastening nut I13 is tightly against the top of the horizontal plate 9. When adjusting the winding position of the strip according to the width of the strip during the actual winding process, the handle 12 is rotated to drive the threaded rod 11 to rotate. Since the threaded rod 11 is threadedly connected to the threaded hole in the center of the horizontal plate 9, and the top of the mounting box 10 has a vertical rod 14 to restrict its rotation, the rotation of the threaded rod 11 will cause the mounting box 10 to move vertically. After adjusting to the appropriate position, tighten the fastening nut I13 to fix the position of the mounting box 10.

[0037] Two screw seats 16 are symmetrically threaded onto the bidirectional threaded screw 15. The bottom end of the screw seat 16 passes through the opening at the bottom of the mounting box 10 and is fixedly fitted with a limiting vertical piece 19. A sliding piece 17 is fixedly fitted on one side of the screw seat 16 to improve its movement stability. The mounting box 10 is provided with a strip-shaped sliding hole 18 for sliding connection with the corresponding sliding piece 17. One end of the bidirectional threaded screw 15 passes through the outside of the mounting box 10 and is fixedly connected to a hand-tightening bolt 20. A fastening nut II 21 is threaded onto the hand-tightening bolt 20. One side of the fastening nut II 21 is tightly pressed against the outer wall of the mounting box 10. When the mounting box 10 is adjusted to a suitable vertical position... Afterwards, rotating the hand-tightening bolt 20 drives the bidirectional threaded screw 15 to rotate. The two screw seats 16 on the bidirectional threaded screw 15 will move relative to or towards each other along the bidirectional threaded screw 15. The limiting vertical piece 19 at the bottom of the screw seat 16 moves accordingly, thereby adjusting the distance between the two limiting vertical pieces 19 to accommodate strips of different widths and limit the winding of the strip. At the same time, the sliding piece 17 on one side of the screw seat 16 slides in the strip-shaped sliding hole 18 of the mounting box 10 to ensure the stability of the movement of the screw seat 16. After adjusting to the appropriate position, tighten the fastening nut II 21 to fix the position of the bidirectional threaded screw 15.

[0038] In practical use, the superconducting strip that needs to be rewound is placed on the unwinding roller 2 and sequentially passed around one of the guide rollers 3, the cylindrical tension sensor 6, and the other guide roller 3, and finally wound onto the winding roller 4. The vertical position of the mounting box 10 and the distance between the two limiting vertical plates 19 are adjusted according to the above method to adapt to the strip width and limit it. After the servo motor 5 is started, its output shaft drives the winding roller 4 to rotate through the coupling to realize the winding of the strip. The cylindrical tension sensor 6 monitors the strip tension in real time and transmits the signal to the servo driver 8. The servo driver 8 adjusts the speed of the servo motor 5 according to the signal to ensure that the strip tension is uniform. After winding is completed, the threaded rod 11 is rotated in the opposite direction to drive the two limiting vertical plates 19 to move upward, and then the coiled strip is taken off the winding roller 4.

[0039] This application can be used for winding superconducting tapes, or in other fields applicable to this application.
