Description

Technical Field

[0001] This utility model relates to metal strip processing equipment technology, and in particular to a large-scale nanocrystalline strip slitting equipment. Background Technology

[0002] Nanocrystalline ribbon, as a high-performance soft magnetic alloy material, is widely used in high-frequency transformers, instrument transformers, sensors, and inductive components due to its excellent magnetic properties. In industrial production, nanocrystalline ribbon is usually prepared in the form of large-size master rolls, which then need to be precisely cut and wound into sub-rolls that meet specific width and length requirements using slitting equipment for downstream applications.

[0003] The quality of the slitting process directly affects the final performance of the nanocrystalline ribbon, with winding tightness and tension uniformity being key control indicators. In traditional slitting equipment, a cylindrical inner ring (coil) is typically placed on the slitting shaft, and the ribbon is then wound around the outer surface of the inner ring. However, for the slitting of large nanocrystalline ribbons, the overall weight and diameter of the roll are very large, generating enormous rotational inertia during high-speed start-up, operation, and braking of the equipment. This inertia easily overcomes the static friction between the slitting shaft and the inner ring, causing relative slippage or slippage between them. Once slippage occurs, the winding tension of the ribbon will instantly become uncontrollable, resulting in problems such as loose inner layers, excessively tight outer layers, or interlayer misalignment. This not only severely damages the sensitive magnetic properties of the nanocrystalline material but may also lead to the scrapping of the entire roll, significantly reducing the production yield.

[0004] Furthermore, to ensure slitting quality, precise control of strip tension, winding speed, and final roll diameter or thickness is required. Many existing equipment's process monitoring systems are relatively independent, lacking real-time online monitoring and closed-loop control of key parameters. Adjustments often rely on operator experience, making it difficult to guarantee consistent product quality in mass production. Simultaneously, during high-speed slitting, if an unexpected strip break occurs and the machine cannot be stopped promptly, it can lead to significant material waste and potential equipment safety risks.

[0005] Therefore, this utility model proposes a large-scale nanocrystalline ribbon slitting device to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a large-scale nanocrystalline ribbon slitting device, which aims to improve the problems of slippage between the slitting shaft and the inner ring, resulting in unstable winding quality, and the lack of integrated real-time online monitoring and automatic control of key parameters in the slitting process, leading to low production efficiency and yield.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A large-scale nanocrystalline ribbon slitting device includes: a base, a first housing, a second housing, a slitting shaft to be slitted, and a slitting shaft assembly.

[0008] The splitting shaft assembly includes a central main shaft arranged along its axial direction, a drive shaft sleeved outside the main shaft and slidable along its axial direction, an upper slider fixed on the outer surface of the drive shaft, slats evenly distributed around the outer side of the drive shaft, and a lower slider fixed on the inner surface of the slats.

[0009] Furthermore, the upper slider and the lower slider are combined through a sloping sliding fit to convert the axial sliding of the drive shaft into the radial expansion or contraction of the slats.

[0010] Preferably, the end of the strip is provided with an integrally formed protrusion, and the end face of the first housing is provided with a limiting groove that slides with the protrusion.

[0011] Preferably, the reel assembly further includes a pneumatic push rod disposed inside the main shaft, the output end of which is connected to the drive shaft.

[0012] Preferably, the large nanocrystalline ribbon slitting equipment further includes a fixed base, a shaft, a mounting plate, a thickness measuring cylinder, and a thickness measuring contact. The thickness measuring cylinder is fixed on the fixed base via the shaft and the mounting plate, and the thickness measuring contact is located at the telescopic end of the thickness measuring cylinder.

[0013] Preferably, the large nanocrystalline ribbon slitting equipment further includes a bracket fixed on the base, and an electromagnetic tension control mechanism and a ribbon breaking grating are fixed on the bracket.

[0014] Preferably, the large nanocrystalline ribbon slitting device further includes a speed control grating disposed on the side of the base.

[0015] Preferably, the large nanocrystalline ribbon slitting equipment further includes a cantilever and a touch screen mounted on the cantilever, the touch screen having a handle.

[0016] Preferably, the large nanocrystalline ribbon slitting equipment further includes a controller, which is electrically connected to the slitting shaft assembly, speed control grating, electromagnetic tension control mechanism, ribbon breakage grating, and thickness measuring cylinder.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting a drive shaft that can slide axially outside the main shaft, and setting an upper slider and a lower slider that slide together by inclined plane between the drive shaft and the strip, the drive shaft is driven to slide by a pneumatic push rod, so that the strip expands radially. This solves the problem of uneven winding tension and unstable finished product quality caused by slippage between the slitting shaft and the inner ring in the prior art. It achieves the technical effect of firmly locking the inner ring to the surface of the slitting shaft assembly and ensuring the stability of the slitting process.

[0018] 2. In this utility model, by setting up a thickness measuring cylinder, a thickness measuring contact, a speed control grating, and a strip breakage grating, and electrically connecting them to the controller, the problem of traditional slitting equipment relying on manual monitoring of thickness and speed, and not responding in time to sudden situations such as strip breakage is solved. The technical effect of real-time online monitoring and automated control of slitting thickness, running speed, and strip integrity is achieved, thereby improving the accuracy and safety of the production process.

[0019] 3. In this utility model, by integrating the radially expandable slitting shaft assembly with the electromagnetic tension control mechanism, the online thickness measurement mechanism, and the adjustable touch screen mounted on the cantilever, the problems of scattered functional modules, poor coordination, and inconvenient operation of existing equipment are solved. This achieves the technical effects of compact overall structure, high degree of automation, and user-friendly human-machine interaction, thereby improving the overall efficiency and reliability of large nanocrystalline ribbon slitting operations.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 This utility model provides a large-scale nanocrystalline ribbon slitting device, which aims to solve the technical problem of unstable finished product quality caused by the ribbon slipping on the surface of the roll during the slitting process in the prior art.

[0024] like Figures 1-3 As shown, the large nanocrystalline ribbon slitting device includes a base 1, a first housing 2 and a second housing 3 respectively fixedly connected to opposite sides of the top surface of the base 1, a slitting shaft 4 rotatably connected to the second housing 3, and a slitting shaft assembly 5 rotatably connected inside the first housing 2.

[0025] Specifically, the reel assembly 5 includes a central spindle 507 arranged along its axial direction. A drive shaft 501 is slidably connected to the outer surface of the spindle 507. The drive shaft 501 can reciprocate along the axial direction of the spindle 507. The inner surface of the upper slider 504 is fixedly connected to the outer surface of the drive shaft 501. Multiple strips 502 are evenly distributed circumferentially on the outer side of the drive shaft 501. The inner surface of each strip 502 is fixedly connected to a lower slider 503. The upper slider 504 and the lower slider 503 are slidably engaged through an inclined surface. When the drive shaft 501 slides along the axial direction of the spindle 507, the upper slider 504 fixed on the drive shaft 501 pushes the lower slider 503. Through the inclined surface engagement structure between the two, the lower slider 503, together with the strips 502 fixedly connected to it, is pushed outward or retracted inward along the radial direction of the reel assembly 5.

[0026] As a preferred embodiment of this utility model, please refer to Figure 1 and Figure 3In order to stably guide the radial movement of the slats 502, a protrusion 506 is integrally formed at the end of each slat 502. A limiting groove 505 is correspondingly provided on the end face of the first housing 2 for the protrusion 506 to slide into. The protrusion 506 slides in cooperation with the groove wall of the limiting groove 505. This structure limits the movement trajectory of the slats 502 and ensures that it remains stable during expansion and contraction.

[0027] As a specific driving method, please refer to [the relevant documentation] again. Figure 3 A pneumatic push rod 508 is provided inside the hollow interior of the main shaft 507. The piston rod output end of the pneumatic push rod 508 is fixedly connected to the end of the drive shaft 501, which is used to provide a power source for the drive shaft 501 to slide along the axial direction of the main shaft 507.

[0028] Please refer to Figure 2 and Figure 5 This embodiment also includes an online thickness measuring mechanism, which includes a fixed base 14, which is fixedly connected to the top surface of the base 1. The thickness measuring cylinder 16 is fixedly connected to the fixed base 14 via a shaft 15 and a mounting plate 17. The thickness measuring contact 18 is installed at the telescopic end of the thickness measuring cylinder 16 and is used to contact the surface of the strip wound on the reel assembly 5 in real time.

[0029] Please refer to Figure 5 A bracket 13 is also fixedly connected to the base 1. The electromagnetic tension control mechanism 7 and the strip breakage grating 8 are both fixedly installed on the top of the bracket 13 and located between the roll to be separated 4 and the roll separation assembly 5, for applying tension to the nanocrystalline ribbon and monitoring whether it breaks.

[0030] To monitor the splitting speed, a speed control grating 6 is installed on one side of the base 1.

[0031] To facilitate human-computer interaction, the device also includes a cantilever 9, with a touch screen 12 mounted at the end of the cantilever 9. A handle 10 is also provided at the edge of the touch screen 12 for easy dragging and rotation of the touch screen 12.

[0032] This embodiment also includes a controller 11, which is electrically connected to the pneumatic push rod 508, the thickness measuring cylinder 16, the electromagnetic tension control mechanism 7, the tape breaking grating 8, and the speed control grating 6, and is used to receive signals from each sensor and centrally control each actuator.

[0033] Working principle: During operation, first connect the power supply and compressed air source, and lock the nanocrystalline ribbon to be slit onto the slit shaft 4 on one side of the second housing 3. The operator passes the end of the ribbon through the electromagnetic tension control mechanism 7 and the tape breaking grating 8 fixed on the top of the bracket 13 in sequence. Then, the inner ring for collecting the slit ribbon is fitted onto the outside of the slit shaft assembly 5 on one side of the first housing 2. At this time, the pneumatic push rod 508 set inside the main shaft 507 is activated. The pneumatic push rod 508 drives the drive shaft 501 connected to it to retract inward along the axial direction of the main shaft 507. During the retraction of the drive shaft 501, the upper slider 504 fixed on its outer surface will move synchronously and push the lower slider 503 fixed to the inner side of the strip 502 radially upward. Since the protrusion 506 at the end of the strip 502 slides inside the limiting groove 505 on the end face of the first housing 2, the strip 502 will stably move outward. The expansion increases the overall radius of the slitting shaft assembly 5, tightening and fixing the inner ring from the inside to prevent slippage during subsequent high-speed rotation. Then, the operator can pull the touch screen 12 mounted on the cantilever 9 to a suitable position via the handle 10, check and set the technical parameters, and then start the equipment. The slitting shaft assembly 5 begins to rotate, and the electromagnetic tension control mechanism 7 applies a preset tension to the strip. At the same time, the thickness measuring cylinder 16 drives the thickness measuring contact 18 to contact the surface of the slitting strip. As the number of winding layers increases, the contraction distance of the thickness measuring cylinder 16 changes. This change is transmitted to the touch screen 12 in real time through the controller 11. During the entire slitting process, the speed control gratings 6 on both sides of the base 1 detect the slitting speed in real time, and the strip breakage grating 8 monitors the integrity of the strip in real time. When the winding thickness or number of turns reaches the set value, the controller 11 controls the equipment to stop automatically, completing the slitting operation.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
