Technical Field
[0001] This utility model belongs to the field of electrical steel strip processing, specifically a tensioning device used in an electrical steel strip processing production line. Background Technology
[0002] Electrical steel, also known as silicon steel, is a special type of steel with good electromagnetic properties, and is widely used in the manufacture of electrical equipment such as power transformers, generators, and motors.
[0003] Electrical steel strips need to be transported on the production line during processing and production. However, existing production lines lack tensioning mechanisms, resulting in insufficient tension in the steel strips during transport. This can easily lead to deformations such as wavy, curled, or warped shapes, affecting the quality and surface flatness of the steel strips. Furthermore, existing production lines lack mechanisms to limit the movement of the steel strips, causing them to easily deviate during transport. This, in turn, affects the stability of the steel strip transport and the subsequent processing quality. Utility Model Content

[0005] The technical solution of this utility model is as follows: a tensioning device used in an electrical steel strip processing production line includes a workbench, a steel strip production furnace installed on one side of the top of the workbench, a limit frame fixedly connected to the side of the top of the workbench away from the steel strip production furnace, sliding sleeves slidably connected to the top two sides of the limit frame via sliding rods, a disc slidably connected inside the sliding sleeve, a sliding plate fixedly connected to the top of the disc extending to the top of the sliding sleeve, a spring provided outside the sliding plate and between the disc and the inner wall of the sliding sleeve, a tensioning roller rotatably connected between the two sliding plates, a first limit plate sleeved on both sides of the outer side of the tensioning roller, and a transmission component and an adjustment component respectively provided on the top of the limit frame.
[0006] In a preferred embodiment, the transmission assembly includes a motor, which is fixedly connected to the top of the limiting frame via a mounting plate. A first synchronous pulley is fixedly connected to the output end of the motor. Threaded rings are rotatably connected to both sides of the inner side of the limiting frame. A second synchronous pulley is fixedly connected to the top of each of the two threaded rings. The first synchronous pulley and the two second synchronous pulleys are respectively connected by two synchronous belts. A ball screw is fixedly connected to the bottom of the sliding sleeve, and the two ball screws are respectively threaded into the interior of the corresponding threaded rings.
[0007] In a preferred embodiment, the adjusting assembly includes a bidirectional lead screw, which is rotatably connected between two slide plates and located above the tensioning roller. Two first limiting plates are respectively threaded to the outer sides of the bidirectional lead screw. A self-locking knob is rotatably connected to the outer side of the slide plate. One end of the bidirectional lead screw extends to the outer side of the slide plate and is fixedly connected to the self-locking knob.
[0008] In a preferred embodiment, a fixing plate is fixedly connected to the outer side of the steel strip production furnace. A second limiting plate is slidably connected to both sides of the top of the fixing plate. Bolts are threadedly connected to the top of the two second limiting plates.

[0011] The beneficial effects of this utility model are as follows:
[0012] This device uses the spring force to drive the tension roller downwards, applying a certain tension to the steel strip and keeping it taut. This prevents wrinkles, creases, or other defects from forming on the steel strip surface due to slack, thus improving the surface quality of the finished steel strip. The tension force can be adjusted at any time. Adjusting the tension force effectively prevents the steel strip from becoming slack due to insufficient tension, which could lead to uneven thickness. Conversely, it avoids excessive local deformation of the steel strip due to excessive tension, which could affect thickness consistency. Appropriate tension adjustment helps ensure uniform steel strip thickness, meeting product quality requirements. Furthermore, the device uses an adjustable-gap first limiting plate to adapt to and limit steel strips of different widths, preventing deviation during transport and improving the stability of the steel strip transmission.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figure 1-5 A tensioning device for an electrical steel strip processing production line includes a workbench 1. A steel strip production furnace 2 is installed on one side of the top of the workbench 1. A limit frame 3 is fixedly connected to the side of the top of the workbench 1 away from the steel strip production furnace 2. Sliding sleeves 4 are slidably connected to both sides of the top of the limit frame 3 via sliding rods 17. A disc 5 is slidably connected inside the sliding sleeve 4. A sliding plate 6 is fixedly connected to the top of the disc 5 extending to the top of the sliding sleeve 4. A spring 7 is provided on the outside of the sliding plate 6 and between the disc 5 and the inner wall of the sliding sleeve 4. A tensioning roller 8 is rotatably connected between the two sliding plates 6. A first limit plate 9 is sleeved on both sides of the outside of the tensioning roller 8. A transmission component and an adjustment component are respectively provided on the top of the limit frame 3.
[0022] Specifically, the transmission assembly includes a motor 11, which is fixedly connected to the top of the limiting frame 3 via a mounting plate. The output end of the motor 11 is fixedly connected to a first synchronous pulley 12. Threaded rings 13 are rotatably connected to both sides of the inside of the limiting frame 3. Second synchronous pulleys 14 are fixedly connected to the top of each of the two threaded rings 13. The first synchronous pulley 12 and the two second synchronous pulleys 14 are respectively connected by two synchronous belts 15. A ball screw 16 is fixedly connected to the bottom of the sliding sleeve 4. The two ball screws 16 are respectively threaded into the inside of the corresponding threaded rings 13. The adjustment assembly includes a bidirectional screw 18, which is rotatably connected between two slide plates 6 and located above the tension roller 8. Two first limiting plates 9 are respectively threaded to the outer sides of the bidirectional screw 18. A self-locking knob 19 is rotatably connected to the outer side of the slide plate 6. One end of the bidirectional screw 18 extends to the outer side of the slide plate 6 and is fixedly connected to the self-locking knob 19.
[0023] Through the above technical solution, the steel strip produced by the steel strip production furnace 2 is first limited by two second limiting plates 21, then the steel strip passes under the tension roller 8, and is then wound by the winding roller 10 and the winding device of the external production line. The springs 7 inside the two sliding sleeves 4 can drive the disc 5 and the slide plate 6 to slide downwards through the elastic force, thereby driving the tension roller 8 downwards through the slide plate 6 to apply a certain tension to the steel strip, keeping it in a taut state. This can prevent wrinkles, creases or other defects from forming on the surface of the steel strip due to slack, thereby improving the surface quality of the finished steel strip. When it is necessary to adjust the tension of the steel strip, the motor 11 is started by the external controller. The output end of the motor 11 drives the first When the first synchronous pulley 12 rotates, it drives the corresponding second synchronous pulley 14 and threaded ring 13 to rotate via two synchronous belts 15. This causes the threaded ring 13 to drive the corresponding ball screw 16 and sliding sleeve 4 to slide under the limit of the slide rod 17 through the threaded connection. When the sliding sleeve 4 slides downward, it can compress the spring 7, thereby increasing the tension of the steel strip. When the sliding sleeve 4 slides upward, it can relieve the compression of the spring 7, thereby reducing the tension of the steel strip. By adjusting the tension, it can effectively avoid the problem that the steel strip may become loose due to insufficient tension, resulting in uneven thickness. At the same time, it can also avoid the problem that excessive tension may cause excessive local deformation of the steel strip, affecting the uniformity of thickness. Regarding the issue of tension, proper adjustment of the tension force helps ensure uniform steel strip thickness, meeting product quality requirements. Furthermore, the first limiting plate 9 outside the tension roller 8 can limit the passing steel strip, preventing deviation during transmission and improving transmission stability. Rotating the self-locking knob 19 drives the bidirectional lead screw 18, which, through a threaded connection, adjusts the spacing of the first limiting plates 9 on both sides under the constraint of the tension roller 8. This allows for adaptation to steel strips of different widths, enhancing the flexibility of the device. The device can also use the spring force 7 to apply downward tension to the steel strip via the tension roller 8, maintaining its tension. This device can prevent wrinkles, creases, or other defects on the steel strip surface caused by slack, thereby improving the surface quality of the finished steel strip. Furthermore, the tension can be adjusted at any time. Adjusting the tension effectively prevents the steel strip from becoming slack due to insufficient tension, which could lead to uneven thickness. Conversely, it avoids excessive local deformation of the steel strip due to excessive tension, which could affect thickness consistency. Appropriate tension adjustment helps ensure uniform steel strip thickness, meeting product quality requirements. Moreover, the device uses an adjustable-gap first limiting plate 9 to adapt to and limit steel strips of different widths, preventing deviation during transmission and improving the stability of the steel strip transmission.
[0024] Specifically, a fixed plate 20 is fixedly connected to one side of the steel strip production furnace 2. A second limiting plate 21 is slidably connected to both sides of the top of the fixed plate 20. Bolts 22 are threadedly connected to the top of the two second limiting plates 21. Threaded holes 23 are equidistantly opened on the top of the fixed plate 20. One end of the bolt 22 extends to the bottom of the second limiting plate 21 and is threadedly connected to the threaded hole 23. The self-locking knob 19 is provided with anti-slip knurling on the outside. A winding roller 10 is rotatably connected to the top of the worktable 1 away from the steel strip production furnace 2 through a fixed frame. The motor 11 is electrically connected to an external controller.
[0025] By using the above technical solution, by loosening the bolt 22 and then adjusting the distance between the two second limit plates 21, steel strips of different widths can be adapted to avoid deviation when the steel strip is transported out of the steel strip production furnace 2. The motor 11 can be quickly controlled by the staff through the external controller.
[0026] In use, the steel strip produced by the steel strip production furnace 2 is first limited by two second limiting plates 21. Then, the steel strip passes under the tension roller 8 and is wound by the winding roller 10 and the winding device of the external production line. The springs 7 inside the two sliding sleeves 4 can drive the disc 5 and the slide plate 6 to slide downwards through the elastic force. This causes the tension roller 8 to apply a certain tension to the steel strip, keeping it taut. This prevents wrinkles, creases, or other defects from forming on the surface of the steel strip due to slack, thereby improving the surface quality of the finished steel strip. The tension of the steel strip needs to be adjusted. During adjustment, the motor 11 is started via an external controller. The output of the motor 11 drives the first synchronous pulley 12 to rotate. The first synchronous pulley 12 then drives the corresponding second synchronous pulley 14 and threaded ring 13 to rotate via two synchronous belts 15. This causes the threaded ring 13 to drive the corresponding ball screw 16 and sliding sleeve 4 to slide under the limit of the slide rod 17 through the threaded connection. When the sliding sleeve 4 slides downward, it can compress the spring 7, thereby increasing the tension on the steel belt. When the sliding sleeve 4 slides upward, it can relieve the compression on the spring 7, thereby reducing the tension on the steel belt. By adjusting the tension, [the following can be achieved]. This effectively prevents the steel strip from becoming loose due to insufficient tension, leading to uneven thickness. Simultaneously, it avoids the problem of excessive local deformation of the steel strip due to excessive tension, affecting thickness consistency. Appropriate tension adjustment helps ensure uniform steel strip thickness, meeting product quality requirements. Furthermore, the first limiting plate 9 outside the tension roller 8 can limit the passing steel strip, preventing deviation during transmission and improving transmission stability. Rotating the self-locking knob 19 drives the bidirectional lead screw 18 to rotate. The bidirectional lead screw 18 can be connected via screw... The connection between the threads causes the first limiting plates 9 on both sides to adjust the spacing under the limit of the tensioning roller 8, thereby adapting to steel strips of different widths and improving the flexibility of the device. The device can use the elastic force of the spring 7 to drive the tensioning roller 8 to apply a certain tension to the steel strip downwards, keeping it in a taut state. This can prevent wrinkles, creases or other defects from appearing on the surface of the steel strip due to slack, thereby improving the surface quality of the finished steel strip. Furthermore, the tension force can be adjusted at any time. By adjusting the tension force, it can effectively prevent the steel strip from becoming slack due to insufficient tension, which could lead to uneven thickness.This also avoids the problem of excessive local deformation of the steel strip due to excessive tension, which could affect the consistency of thickness. Appropriate tension adjustment helps ensure uniform steel strip thickness, meeting product quality requirements. Furthermore, this device, through the adjustable-gap first limiting plate 9, can adapt to and limit steel strips of different widths, preventing deviation during transmission and improving transmission stability. By loosening bolt 22 and adjusting the distance between the two second limiting plates 21, it can adapt to steel strips of different widths, preventing deviation when the steel strip exits the steel strip production furnace 2. An external controller allows for convenient and quick control of the motor 11 by the operator.
