Description

Technical Field

[0001] This invention relates to the field of superconducting tape slitting technology, and in particular to a superconducting tape slitting guide device. Background Technology

[0002] Second-generation high-temperature superconducting REBCO (REBa2Cu3O) 7-x Rare earth elements (RE, referring to elements like Y and Gd) are widely used in high-temperature superconducting magnets, particle accelerators, and other fields. Because second-generation high-temperature superconducting tapes use wider basebands during production, their width is also relatively wide, typically 12mm or 10mm. Therefore, in practical applications, these wider tapes need to be slit to appropriate widths, such as 4mm or 8mm. Currently, the commonly used mechanical slitting method primarily utilizes slitting cutters to cut the tape. To achieve more precise cutting, a slitting guide device needs to be added before the rotary shear cutter to ensure the tape doesn't wobble during slitting. Conventional guide devices have low precision in adjusting the tape's width direction, leading to errors in the width of the slit tape and failing to meet accuracy requirements. Therefore, there is an urgent need for a superconducting tape slitting guide device with higher precision in controlling the tape's width direction. Summary of the Invention

[0003] The purpose of this invention is to provide a superconducting tape slitting and guiding device to solve the problems existing in the prior art and to achieve higher precision in controlling the position of the tape in the width direction.

[0004] To achieve the above objectives, the present invention provides the following solution:

[0005] This invention provides a superconducting tape slitting and guiding device, comprising: a sliding device and a guiding structure. The sliding device includes an upper sliding platform, a lower sliding platform, an adjusting screw, and two fixed blocks. The upper sliding platform is slidably connected to the upper side of the lower sliding platform along a first direction. The guiding structure is fixedly connected to the upper side of the upper sliding platform. The two fixed blocks are respectively fixedly connected to the lower sliding platform and the upper sliding platform. One of the fixed blocks is provided with a threaded hole communicating with both sides of the fixed block in the first direction. The adjusting screw passes through the threaded hole and is threadedly connected to the threaded hole. One end of the adjusting screw is fixedly connected to the other fixed block in the axial direction of the adjusting screw and forms a rotatable connection in the circumferential direction of the adjusting screw. Rotating the adjusting screw allows the upper sliding platform to slide relative to the lower sliding platform in the first direction. The guiding structure has a guiding channel for threading superconducting tape. One end of the guiding channel is used to set a cutter. The superconducting tape can move along the guiding channel and be slid by the cutter.

[0006] In some embodiments, a base is also included, with the sliding platform fixedly connected to the upper side of the base.

[0007] In some embodiments, the guide structure includes a fixed base, a first clamp, and a second clamp. The fixed base is fixedly connected to the upper side of the upper slide table, and the first clamp and the second clamp are slidably connected to the upper side of the fixed base. The first clamp and the second clamp are arranged opposite to each other in the first direction and are both capable of sliding in the first direction. The first clamp and the second clamp are used to form the guide channel.

[0008] In some embodiments, both the first clamp and the second clamp include a base plate and a side plate. The two base plates are slidably connected to the upper side of the fixed base along the first direction, and the two side plates are respectively fixedly connected to the two base plates. The two side plates are arranged opposite to each other in the first direction, and the guide channel is formed between the two side plates.

[0009] In some embodiments, the guide structure further includes a sliding bolt and a nut. The base plate has a through hole, the fixing seat has a strip hole, and the lower side of the fixing seat has a groove. The strip hole and the groove both extend along a straight line parallel to the first direction. The through hole, the strip hole, and the groove are sequentially connected and correspond in position. The sliding bolt passes through the through hole and the strip hole and extends into the groove at the bottom of the fixing seat. The nut is screwed onto the end of the sliding bolt that extends into the groove and is located within the groove.

[0010] In some embodiments, the guide structure further includes a slide rod and a pressure roller. The side plates of the first clamp and the second clamp are respectively provided with a first slide groove and a second slide groove. The number of first slide grooves and second slide grooves is the same. Each first slide groove corresponds to the position of a second slide groove. The two ends of the slide rod are slidably connected in a first slide groove and a second slide groove corresponding to the position, respectively. The pressure roller is rotatably connected to the slide rod around the axis of the slide rod.

[0011] In some embodiments, the guide structure further includes a limiting strip, which is fixedly connected to the fixed base between the first clamp and the second clamp. The upper surface of the limiting strip protrudes from the upper surface of the fixed base, and both ends of the limiting strip extend out from the upper side of the fixed base. Both ends of the limiting strip are provided with chamfers.

[0012] In some embodiments, both the first clamp and the second clamp include limiting portions. The two limiting portions are respectively fixedly connected to the ends of the two side plates that are close to the cutter. The two limiting portions are located on both sides of the end of the limiting strip that extends out of the fixed base. The upper side of the limiting portion protrudes from the upper side of the limiting strip. The distance between the two limiting portions is equal to the distance between the side plates.

[0013] In some embodiments, the system further includes support rods and guide wheels. Two support rods are provided, with one end of each support rod fixedly connected to opposite sides of the fixed base, and the other end of each support rod being a first end. Both ends of the guide wheels are rotatably connected to the two first ends around a straight line parallel to the first direction, with the end of the guide wheel closer to the guide channel and farther from the cutter.

[0014] In some embodiments, the pressure roller is made of silicone.

[0015] The present invention achieves the following technical effects compared to the prior art:

[0016] The superconducting tape slitting and guiding device provided by this invention is used to be positioned between two pay-off reels, on which superconducting tape is wound. The superconducting tape can pass through a guide channel and be wound onto another pay-off reel. The rotation of the two pay-off reels allows the superconducting tape to move along the guide channel. A cutter is set at one end of the guide channel, which can then slit the superconducting tape. Before slitting, an adjusting screw is turned. As the depth of the adjusting screw changes within the threaded hole, the adjusting screw can push or pull back the second fixing block, causing the upper slide to slide relative to the lower slide in a first direction. This ensures that the position of the tape to be slit is directly opposite the cutter. By converting the rotation of the adjusting screw along the thread into the linear motion of the upper slide, the adjustment accuracy is improved. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The purpose of this invention is to provide a superconducting tape slitting and guiding device to solve the problems existing in the prior art and to achieve higher precision in controlling the position of the tape in the width direction.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This invention provides a superconducting tape slitting and guiding device, such as... Figure 1-2 As shown, the device includes a sliding device 1 and a guide structure 3. The sliding device 1 includes an upper sliding table 12, a lower sliding table 11, an adjusting screw 15, and two fixed blocks. The upper sliding table 12 is slidably connected to the upper side of the lower sliding table 11 in a first direction. The guide structure 3 is fixedly connected to the upper side of the upper sliding table 12. The two fixed blocks are respectively fixedly connected to the lower sliding table 11 and the upper sliding table 12. One of the fixed blocks is provided with a threaded hole in the first direction that connects the two sides of the fixed block. The adjusting screw 15 passes through the threaded hole and is threadedly connected to the threaded hole. One end of the adjusting screw 15 is fixedly connected to the other fixed block in the axial direction of the adjusting screw 15 and forms a rotatable connection in the circumferential direction of the adjusting screw 15. Rotating the adjusting screw 15 can make the upper sliding table 12 slide relative to the lower sliding table 11 in the first direction. The guide structure 3 has a guide channel 36. The guide channel 36 is used to pass through the superconducting tape. One end of the guide channel 36 is used to set a cutter. The superconducting tape can move along the guide channel 36 and be cut by the cutter.

[0025] The superconducting tape slitting and guiding device provided by this invention is used to be positioned between two pay-off reels, on which superconducting tape is wound. The superconducting tape can pass through a guide channel 36 and be wound onto another pay-off reel. The rotation of the two pay-off reels allows the superconducting tape to move along the guide channel 36. A cutter is provided at one end of the guide channel 36, which can then be used to slit the superconducting tape. Before slitting, the adjusting screw 15 is turned. As the depth of the adjusting screw 15 changes within the threaded hole, the adjusting screw 15 can push or pull back the second fixing block 14 and cause the upper slide 12 to slide relative to the lower slide 11 in a first direction, so that the position where the tape needs to be slit is directly opposite the cutter. By converting the rotation of the adjusting screw 15 along the thread into the linear motion of the upper slide 12, the adjustment accuracy is improved. The side of the lower slide 11 facing away from the first side is the third side, and the side of the upper slide 12 facing away from the second side is the fourth side. A limiting plate 16 is fixedly connected to the third side, and a limiting groove extending along the first direction is provided on the limiting plate 16. The position of the limiting groove corresponds to the fourth side. A handle 17 passes through the limiting groove and is fixedly connected to the fourth side. By pushing and pulling the handle 17, the operator can move the slide within the range of the limiting groove. The two fixing blocks are the first fixing block 13 and the second fixing block 14. The first fixing block 13 is fixedly connected to the lower slide 11, and the second fixing block 14 is fixedly connected to the upper slide 12. An adjusting screw 15 passes through the first fixing block 13 and is threadedly connected to the first fixing block 13. One end of the adjusting screw 15 is rotatably connected to the second fixing block 14. The sliding device 1 can be a Xinfengheng displacement worktable (model LX80-L). This model of displacement worktable can realize fine adjustment of the upper slide 12 relative to the lower slide 11 with an accuracy of 0.01mm.

[0026] It should be noted that one end of the adjusting screw 15 can be connected to the second fixed block 14 in the following way: for example, a hole can be made in the second fixed block 14, and a bearing can be installed in the hole. The outer ring of the bearing is fixedly connected to the inner wall of the hole, and one end of the adjusting screw 15 is fixedly connected to the inner ring of the bearing.

[0027] In this first embodiment, the superconducting tape slitting and guiding device provided by the present invention further includes a base 2, and a sliding platform 11 is fixedly connected to the upper side of the base 2. The base 2 can provide support for the sliding device 1 and improve the stability of the sliding device 1.

[0028] In this embodiment, the guide structure 3 includes a fixed base 31, a first clamp 32, and a second clamp 33. The fixed base 31 is fixedly connected to the upper side of the upper slide table 12. The first clamp 32 and the second clamp 33 are both slidably connected to the upper side of the fixed base 31. The first clamp 32 and the second clamp 33 are arranged opposite to each other in a first direction and can both slide in the first direction, forming a guide channel 36 between the first clamp 32 and the second clamp 33. In order to adapt the width of the guide channel 36 to strips of different widths, the position of the first clamp 32 and the second clamp 33 in the first direction can be adjusted to adjust the width of the guide channel 36.

[0029] In this first embodiment, both the first clamp 32 and the second clamp 33 include a base plate 34 and a side plate 35. The two base plates 34 are slidably connected to the upper side of the fixed base 31 along a first direction. The two side plates 35 are respectively fixedly connected to the two base plates 34 and are arranged opposite to each other in the first direction, forming a guide channel 36 between them. When threading the strip, the strip is placed between the two side plates 35, with each side of the strip contacting one side of each of the two side plates 35. The side plates 35 effectively limit the movement of the strip.

[0030] In this embodiment, the guide structure 3 further includes a sliding bolt and a nut. The base plate 34 is provided with a through hole 341, the fixing seat 31 is provided with a strip hole 311, and the lower side of the fixing seat 31 is provided with a groove 312. The strip hole 311 and the groove 312 both extend along a straight line parallel to the first direction. The through hole 341, the strip hole 311 and the groove 312 are connected in sequence and their positions correspond. The sliding bolt passes through the through hole 341 and the strip hole 311 and extends into the groove 312 at the bottom of the fixing seat 31. The nut is screwed onto the end of the sliding bolt that extends into the groove 312 and is located in the groove 312 and is used to limit the sliding bolt in the vertical direction. The groove 312 at the bottom of the fixed base 31 provides a space for the nut to be received; when it is necessary to adjust the position of the first clamp 32 or the second clamp 33, the base plate 34 can be pushed manually and the sliding bolt can be slid along the strip hole 311 and the nut can be slid along the groove 312, thereby realizing the adjustment of the position of the first clamp 32 or the second clamp 33.

[0031] In this embodiment, the guide structure 3 further includes a slide rod 37 and a pressure roller 371. The side plates 35 of the first clamp 32 and the second clamp 33 are respectively provided with a first groove and a second groove. The number of first grooves and second grooves is the same, and each first groove corresponds to a second groove. The two ends of the slide rod 37 are slidably connected to a corresponding first groove and a corresponding second groove. The pressure roller 371 is rotatably connected to the slide rod 37 around its axis. Before the strip is threaded into the guide channel 36, the pressure roller 371 can be moved upwards, and the strip can be threaded below it. Then, the pressure roller 371 is moved downwards to press the strip firmly. This prevents the strip from moving vertically and further improves the accuracy of cutting.

[0032] In this first embodiment, the guide structure 3 further includes a limiting strip 38, which is fixedly connected to a fixing base 31 between the first clamp 32 and the second clamp 33. The upper surface of the limiting strip 38 protrudes from the upper surface of the fixing base 31, and both ends of the limiting strip 38 extend beyond the upper side of the fixing base 31. At least the upper part of both ends of the limiting strip 38 is chamfered. When threading the strip, the two feed rollers used for winding the strip can be placed below the two ends of the limiting strip 38, so that the strip is tightened and fits against the upper side of the limiting strip 38. The chamfers at both ends of the limiting strip 38 can prevent the strip from being damaged by sharp edges.

[0033] In this embodiment, both the first clamp 32 and the second clamp 33 include a limiting part 39. The two limiting parts 39 are respectively fixedly connected to the ends of the two side plates 35 that are close to the cutter. The two limiting parts 39 are located on both sides of the end of the limiting strip 38 extending from the fixed base 31. The upper side of the limiting part 39 protrudes from the upper side of the limiting strip 38, and the distance between the two limiting parts 39 is equal to the distance between the side plates 35. The limiting parts 39 can limit the strip material on the end of the limiting strip 38 extending from the fixed base 31, thereby preventing strip material displacement and further improving the accuracy of slitting.

[0034] In this first embodiment, the superconducting tape slitting and guiding device provided by the present invention further includes support rods 4 and guide wheels 5. Two support rods 4 are provided, with one end of each rod fixedly connected to opposite sides of the fixed base 31, and the other end of each rod serving as a first end. Both ends of the guide wheels 5 are rotatably connected to the two first ends around a straight line parallel to a first direction. The end of the guide wheel 5 is closer to the guide channel 36 and further away from the cutter. When threading the tape, the tape first contacts the guide wheel 5 and then passes through the guide channel 36. As the tape moves, it drives the guide wheel 5 to rotate. By providing the guide wheel 5, support is provided for the tape before it enters the guide channel 36, making the tape move more smoothly. The guide wheel 5 can be made of materials such as stainless steel, silicone, or rubber.

[0035] In this first embodiment, the pressure roller 371 is made of silicone. The silicone pressure roller 371 is relatively soft and can prevent the strip from being crushed.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
