Description

Technical Field

[0001] This utility model relates to the technical field of strip winding equipment, and in particular to a disc diameter fixing device for slitting nanocrystalline strips. Background Technology

[0002] Nanocrystalline ribbon, as an advanced soft magnetic material, has wide applications in electronics, power, and other fields. Slitting and winding are crucial steps in its production process to ensure product quality. During slitting, a coiling device is typically used to rewind the slit narrow ribbon into rolls.

[0003] Existing coiling equipment typically uses a core with a fixed diameter. When producing strip coils with different inner diameter specifications, the entire core must be replaced. This is not only cumbersome and labor-intensive, but also requires multiple cores for different specifications of products, leading to increased production costs, low efficiency, and difficulty in adapting to the flexible production needs of multiple varieties and small batches.

[0004] To address this issue, some adjustable-diameter winding devices have emerged. However, most of these devices form the winding support structure by expanding multiple independent rods, resulting in a winding surface that is not a continuous cylindrical surface but rather cage-like or fence-like. This structure is usable when winding conventional metal or fabric strips, but nanocrystalline ribbons have the physical characteristics of being thin, hard, and brittle, making them extremely sensitive to stress. If wound on such a discontinuous surface, the ribbon can only contact the dispersed rods under tension, leading to severe stress concentration in the suspended portions between the rods. This can easily cause the ribbon to break, fracture, or develop permanent creases in the initial stages of winding, resulting in significant material waste and reduced product quality. Furthermore, existing devices are not convenient or precise enough for adjusting the limits of ribbons of different widths. Therefore, this invention proposes a disc diameter fixing device for slitting nanocrystalline ribbons to overcome the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a disk diameter fixing device for slitting nanocrystalline ribbon, which aims to improve the problems of fixed winding disk diameter, inability to adapt to different specifications of production requirements, and stress concentration damage to brittle ribbon caused by the discontinuous winding surface of the device with adjustable disk diameter in the existing nanocrystalline ribbon slitting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A device for fixing the diameter of a nanocrystalline ribbon for slitting includes: a drive motor, a ribbon body, a fixing frame disposed between the ribbon bodies, a ribbon diameter adjustment component for driving the radial dimension change of the fixing frame, and a limiting component for axial positioning of the ribbon.

[0007] The fixing frame is composed of multiple tile-shaped arc plates, the outer surfaces of which together form a continuous cylindrical winding surface.

[0008] Furthermore, the disc diameter adjustment assembly includes a strut connected to the inner side of multiple tile-shaped arc plates, the strut being used to drive the multiple tile-shaped arc plates to expand or contract radially.

[0009] Preferably, the disc diameter adjustment assembly further includes an electric push rod and a hinge seat hinged to the output end of the electric push rod, with one end of the support rod connected to the hinge seat and the other end connected to the fixed frame.

[0010] Preferably, a guide rod is provided between the discs, and a connecting hole is provided on the fixing frame to slide with the guide rod.

[0011] Preferably, the limiting component includes a limiting plate and a sliding seat for locking the limiting plate.

[0012] Preferably, the sliding seat is provided with a stabilizing block, and a screw is internally threaded onto the stabilizing block. One end of the screw is connected to a knob, and the other end is used to abut against the fixing frame.

[0013] Preferably, the sliding seat is provided with a T-slot, and the stabilizing block is provided with a T-block that slides in conjunction with the T-slot.

[0014] Preferably, the output shaft of the drive motor is connected to the disc body.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by setting a fixed frame composed of multiple tile-shaped arc plates and using an electric push rod to drive the support rod to radially open or close the arc plate, the problem of fixed disc diameter in the existing coiling device and inability to adapt to different specifications of production needs is solved. It also avoids the problem of damage or breakage caused by stress concentration on brittle materials such as nanocrystalline ribbons due to discontinuous winding. The technical effect of electric precise adjustment of disc diameter and continuous smooth winding surface for the ribbon is achieved.

[0016] 2. In this utility model, by setting a limiting disc that can move along the axis and be locked by a screw, the problem of inconvenient adjustment of the limiting device and inability to adapt to coils of different width strips in the prior art is solved. The technical effect of being able to quickly and reliably limit the axial movement of strips of different widths is achieved, ensuring the neatness of the coils.

[0017] 3. In this utility model, by setting a sliding fit structure of T-block and T-slot between the sliding seat and the stabilizing block of the limiting component, the problem of positional interference or ineffective clamping between the locking mechanism and the fixed frame of the limiting component when the disc diameter changes is solved. This achieves the technical effect that the limiting component can adapt to different disc diameters and always maintain reliable locking, thereby improving the overall coordination and applicability of the device.

[0020] 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.

[0021] Reference Figures 1-5 This utility model provides a device for fixing the diameter of a nanocrystalline strip during winding, which aims to solve the problem that the winding core of the existing winding device is a discontinuous surface, which easily causes stress concentration and leads to strip breakage or damage when winding brittle strips such as nanocrystalline strips.

[0022] As shown in the figure, the nanocrystalline ribbon slitting and winding disc diameter fixing device includes a drive motor 1, a disc body 2, a fixing frame 3, a disc diameter adjustment component 4, and a limiting component 5. The output shaft of the drive motor 1 is fixedly connected to the disc body 2 to drive its rotation. The fixing frame 3 is arranged between the disc bodies 2 for winding the ribbon. The disc diameter adjustment component 4 is connected to the fixing frame 3 to drive the radial dimension of the fixing frame 3 to change. The limiting component 5 is also arranged between the disc bodies 2 for axial positioning of the wound ribbon.

[0023] The nanocrystalline ribbon-ribbon slitting device also includes a disc diameter adjustment component 4 for driving the radial dimension change of the fixing frame 3, and a limiting component 5 for axial positioning of the ribbon. The fixing frame 3 is composed of multiple tile-shaped arc plates, the outer surfaces of which together form a continuous cylindrical winding surface for winding the ribbon.

[0024] Specifically, the disc diameter adjustment assembly 4 includes an electric push rod 401. The output end of the electric push rod 401 is rotatably connected to the hinge seat 402. Multiple support rods 403 are rotatably connected to the hinge seat 402. The other end of each support rod 403 is rotatably connected to the inner side of a tile-shaped arc plate. The telescopic movement of the electric push rod 401 is converted into the radial expansion or contraction movement of the fixed frame 3 through the hinge seat 402 and the support rods 403. To ensure the stability of the fixed frame 3 during the adjustment process, a guide rod 405 is fixedly connected between the disc bodies 2 at both ends. A connection hole 404 is provided on the fixed frame 3. The fixed frame 3 is slidably sleeved on the guide rod 405 through the connection hole 404.

[0025] The limiting assembly 5 includes a limiting disk 501 that can move along the axial direction of the equipment. The limiting disk 501 is fixedly connected to the sliding seat 503. A T-slot 502 is provided on the sliding seat 503. A T-block 504 is slidably fitted in the T-slot 502. The T-block 504 is fixedly connected to the stabilizing block 505. A screw 506 is threadedly connected to the stabilizing block 505. One end of the screw 506 passes through the stabilizing block 505 and is fixedly connected to a knob 507. The other end of the screw 506 can pass through the sliding seat 503 to abut against the fixing frame 3, thereby axially locking the limiting disk 501.

[0026] In a preferred embodiment, the disc diameter adjustment assembly 4 includes an electric push rod 401. The output end of the electric push rod 401 is rotatably connected to the hinge seat 402. Multiple support rods 403 are rotatably connected to the hinge seat 402. The other end of the support rods 403 is rotatably connected to the inner side of the fixed frame 3. This structure enables precise electric adjustment of the disc diameter.

[0027] In another preferred embodiment, to ensure the stability of the fixed frame 3 during radial movement, a guide rod 405 is fixedly connected between the two discs 2. A connecting hole 404 is provided on the fixed frame 3. The fixed frame 3 is slidably sleeved on the guide rod 405 through the connecting hole 404. This structure is used to guide the fixed frame 3 to move radially smoothly.

[0028] In one specific embodiment, the limiting component 5 includes a limiting disk 501 and a sliding seat 503 fixedly connected to the limiting disk 501. The sliding seat 503 is used to support the limiting disk 501 and realize its axial movement and locking.

[0029] To reliably lock the limiting component 5, a stabilizing block 505 is provided on the sliding seat 503. A screw 506 is internally threaded onto the stabilizing block 505. One end of the screw 506 is fixedly connected to a knob 507 for manual rotation, and the other end of the screw 506 is used to abut against the fixing frame 3.

[0030] To enable the limiting component 5 to adapt to the radial position change of the fixing frame 3 caused by the change of the disc diameter, a T-slot 502 is provided on the sliding seat 503, and a T-block 504 is fixedly connected to the stabilizing block 505. The T-block 504 slides in conjunction with the T-slot 502. This structure allows the stabilizing block 505 to adaptively adjust its height relative to the sliding seat 503.

[0031] In this embodiment, the output shaft of the drive motor 1 is fixedly connected to one of the disc bodies 2, and is used to drive the entire winding device to rotate.

[0032] The control circuits for the drive motor 1 and the electric push rod 401 can be implemented by those skilled in the art using existing mature control systems, which are well-known technologies in the field and will not be described in detail here.

[0033] Working principle: During operation, the electric push rod 401 inside the disc diameter adjustment assembly 4 is activated first according to production requirements. If the electric push rod 401 retracts, it pulls the hinge seat 402. The hinge seat 402, through multiple support rods 403, expands the multiple tile-shaped arc plates forming the fixed frame 3 outward to increase the winding disc diameter. Conversely, if the electric push rod 401 extends, it pushes the hinge seat 402 and pulls the multiple tile-shaped arc plates inward through the support rods 403 to decrease the winding disc diameter. Throughout the adjustment process, the fixed frame 3 slides smoothly on the guide rod 405 through the connecting hole 404. After adjustment, the outer surfaces of the multiple tile-shaped arc plates together form a continuous cylindrical winding surface of the required diameter. Subsequently, according to the strip width, the limiting plate of the limiting assembly 5 is manually moved. 501 is moved to the appropriate position, and then the knob 507 is rotated. The knob 507 drives the screw 506 to rotate in the stabilizing block 505 until the end of the screw 506 passes through the sliding seat 503 and is tightly pressed against the outer wall of the fixed frame 3, thereby completing the axial locking of the limiting disc 501. During this process, the T-block 504 can slide automatically in the T-slot 502 to adapt to the radial position of the fixed frame 3 under different disc diameters. After the above adjustment is completed, the strip is fixed on the fixed frame 3, and the drive motor 1 is started. The drive motor 1 drives the disc body 2 and the fixed frame 3, disc diameter adjustment component 4 and limiting component 5 to rotate as a whole, so that the nanocrystalline strip is evenly wound on the continuous cylindrical winding surface of the fixed frame 3. The limiting discs 501 on both sides constrain the edge of the strip to ensure the neatness of the winding.

[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.
