Description

Technical Field

[0001] This utility model relates to the field of cold rolling technology, and in particular to a cold rolling device for controlling the deviation of galvanized strip steel. Background Technology

[0002] With the continuous increase in demand for galvanized strip steel from industries such as automotive and construction, the cold rolling process, as the core link in galvanized strip steel production, has seen its strip deviation during conveying become a key factor restricting product quality and production efficiency. If deviation occurs during the cold rolling conveying stage, galvanized strip steel is prone to quality defects such as edge damage, coating scratches, and coiling disc shape. In severe cases, it can even lead to strip breakage and shutdown, increasing production costs and accelerating equipment wear. Therefore, developing efficient and adaptable deviation control devices is an urgent need in the field of galvanized strip steel cold rolling production.

[0003] Currently, deviation control in the cold rolling process of galvanized strip steel mainly adopts methods such as fixed correction rollers, tension adjustment mechanisms, or manual adjustment. Fixed correction rollers can only be adapted to strip steel of a single width, and frequent replacement of parts is required when producing multiple specifications. Traditional tension adjustment mechanisms have insufficient deviation control accuracy for thin strip steel and are prone to exacerbating deviation problems due to tension fluctuations. Some limit structures adopt rigid contact designs, lacking buffer protection, and are prone to scratching the coating on the surface of the strip steel. Manual adjustment methods have slow response speed and are difficult to match the rhythm of high-speed cold rolling production lines. Utility Model Content

[0004] This utility model mainly provides a cold rolling device for controlling the deviation of galvanized strip steel that can be adapted to limit the width of strip steel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cold rolling device for controlling deviation of galvanized strip steel, comprising: a ring plate, conveying rollers installed at equal intervals inside the ring plate, movable plates provided inside the ring plate near both ends, a bidirectional screw provided between the two movable plates near the center, both ends of the bidirectional screw penetrating the movable plates and threadedly connected thereto, a telescopic rod fixedly connected to one side wall of each movable plate between the conveying rollers, a spring sleeved on the surface of each telescopic rod, a U-shaped component fixedly connected to one end of each telescopic rod and spring, a limiting roller rotatably connected to the inside of each U-shaped component by bearings, and annular grooves formed on the surface of each limiting roller.

[0006] Preferably, support legs are fixedly connected to the bottom of the ring plate and near the four corners. The bottom of each support leg is trapezoidal. This arrangement increases the contact area with the ground, improves the overall stability of the device, avoids device displacement caused by equipment vibration during cold rolling, and ensures the smoothness of strip steel conveying.

[0007] Preferably, square holes are provided at both ends of the ring plate. With the above arrangement, the strip steel can be fed in through the square holes and enter through the square holes at one end of the ring plate. After the strip steel is conveyed, it can be sent out through the square holes at the other end, which reduces the risk of scratch damage to the edge of the strip steel.

[0008] Preferably, both ends of the bidirectional screw pass through the ring plate and are rotatably connected to its bearings. A drive motor is fixedly connected to one side wall of the ring plate near the center. The output end of the drive motor is fixedly connected to one end of the bidirectional screw. With the above configuration, the drive motor can directly drive the bidirectional screw, replacing the manual adjustment method, improving the efficiency and accuracy of the moving plate spacing adjustment, adapting to the rhythm of the high-speed cold rolling production line, and reducing the cost of manual intervention.

[0009] Preferably, a control panel is fixedly installed on one side wall of the ring plate near one end. The control panel is electrically connected to the drive motor. With the above configuration, the control signal can be sent to the drive motor through the control panel on the ring plate according to the strip width parameter, so as to control the start, stop, forward and reverse rotation and rotation duration of the motor, thereby accurately adjusting the spacing of the moving plates and adapting to galvanized strips of different specifications.

[0010] Preferably, two limiting rods are provided on both sides of the bidirectional screw. Both ends of the limiting rods pass through the movable plate and are slidably connected to it. Both ends of the limiting rods are fixedly connected to the inner wall of the ring plate. With the above arrangement, when the bidirectional screw rotates, the movable plate slides along the limiting rods on both sides. The limiting rods prevent the movable plate from rotating with the screw, ensuring that the movable plate always maintains horizontal movement. This allows the limiting rollers on both sides to accurately align with the edge of the strip steel and maintain the embedded positioning effect of the ring groove.

[0011] Compared with existing technologies, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the bidirectional screw is driven by a drive motor to rotate, and the spacing of the moving plate can be adjusted synchronously with the limit rod, which can flexibly adapt to galvanized steel strips of different widths without the need for frequent replacement of parts, thus improving production adaptability.

[0012] 2. In this utility model, the spring outside the telescopic rod provides elastic buffer for the limiting roller, avoiding rigid contact that could scratch the strip steel coating and edges, thus ensuring the surface quality of the product.

[0013] 3. In this utility model, the control panel is used to control the drive motor to realize automated spacing adjustment, which replaces manual operation, improves adjustment efficiency and accuracy, and is suitable for high-speed cold rolling production lines.

[0014] 4. In this utility model, the annular groove on the surface of the limiting roller can be embedded into the edge of the strip steel. Combined with the conveying action of the conveying roller, it can achieve precise lateral limiting of the strip steel, effectively reduce the probability of deviation, and reduce quality defects and equipment wear.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figures 1-4This utility model provides a technical solution: a cold rolling device for controlling deviation of galvanized strip steel, comprising: a ring plate 1, conveying rollers 4 installed at equal intervals inside the ring plate 1, movable plates 5 arranged inside the ring plate 1 near both ends, a bidirectional screw 6 arranged between the two movable plates 5 near the center, both ends of the bidirectional screw 6 passing through the movable plates 5 and threadedly connected to them, a telescopic rod 9 fixedly connected to one side wall of the movable plates 5 between the conveying rollers 4, a spring 10 sleeved on the surface of each telescopic rod 9, a U-shaped piece 11 fixedly connected to one end of each telescopic rod 9 and spring 10, and a limiting roller 12 rotatably connected to the inside of the U-shaped piece 11 by a bearing. The surface of the 12 ring plate has annular grooves 13. With the above configuration, the drive assembly can be activated to drive the bidirectional screw 6 to rotate according to the width of the strip to be conveyed, so that the two moving plates 5 move towards or away from each other along the limiting structure to adjust to the spacing that matches the width of the strip. The strip is fed into the conveying roller 4 inside the ring plate 1. The telescopic rod 9 on the side wall of the moving plate 5 and the spring 10 push the U-shaped part 11 so that the limiting roller 12 fits against the edge of the strip and the edge of the strip is embedded in the annular groove 13 of the limiting roller 12. When the strip moves with the conveying roller 4, the limiting roller 12 rotates synchronously and the spring 10 adapts to the slight fluctuations of the strip, so as to achieve a stable limiting conveying effect.

[0020] like Figure 1 As shown, support legs 2 are fixedly connected to the bottom of the ring plate 1 and near the four corners. The bottom of the support legs 2 is trapezoidal. This arrangement increases the contact area with the ground, improves the overall placement stability of the device, avoids device displacement caused by equipment vibration during cold rolling, and ensures the smoothness of strip steel conveying.

[0021] like Figure 2 As shown, square holes 3 are opened at both ends of the ring plate 1. With the above-mentioned arrangement, the strip steel can be fed in through the square holes 3 and enter through the square holes 3 at one end of the ring plate 1. After the strip steel is conveyed, it can be sent out through the square holes 3 at the other end, which reduces the risk of scraping damage to the edge of the strip steel.

[0022] like Figure 2 and Figure 3 As shown, both ends of the bidirectional screw 6 pass through the ring plate 1 and are rotatably connected to its bearings. A drive motor 7 is fixedly connected to one side wall of the ring plate 1 near the center. The output end of the drive motor 7 is fixedly connected to one end of the bidirectional screw 6. Through the above arrangement, the drive motor 7 can directly drive the bidirectional screw 6, replacing the manual adjustment method, improving the efficiency and accuracy of the spacing adjustment of the moving plate 5, adapting to the rhythm of the high-speed cold rolling production line, and reducing the cost of manual intervention.

[0023] like Figure 1As shown, a control panel 8 is fixedly installed on one side wall of the ring plate 1 near one end. The control panel 8 is electrically connected to the drive motor 7. With the above settings, the control panel 8 on the ring plate 1 can send control signals to the drive motor 7 according to the strip width parameters, control the start, stop, forward and reverse rotation and rotation duration of the motor, thereby accurately adjusting the spacing of the moving plate 5 to adapt to galvanized strips of different specifications.

[0024] like Figure 4 As shown, two limiting rods 14 are provided on both sides of the bidirectional screw 6. Both ends of the limiting rods 14 pass through the moving plate 5 and are slidably connected to it. Both ends of the limiting rods 14 are fixedly connected to the inner wall of the ring plate 1. With the above arrangement, when the bidirectional screw 6 rotates, the moving plate 5 slides along the limiting rods 14 on both sides. The limiting rods 14 prevent the moving plate 5 from rotating with the screw, ensuring that the moving plate 5 always maintains horizontal movement, so that the limiting rollers 12 on both sides can accurately align with the edge of the strip steel and maintain the embedded positioning effect of the ring groove 13.

[0025] The operating method and working principle of this device are as follows: First, based on the width of the galvanized steel strip to be conveyed, start the drive motor 7 via the control panel 8 on the ring plate 1. The output end of the drive motor 7 drives the bidirectional screw 6 to rotate. Since the bidirectional screw 6 is threadedly connected to the moving plate 5, and the moving plate 5 slides along the limit rods 14 on both sides, the two moving plates 5 will move towards or away from each other along the bidirectional screw 6, adjusting to a spacing that matches the width of the steel strip. Then, the galvanized steel strip is fed through the square hole 3 at one end of the ring plate 1, and the strip falls onto the conveyor roller 4. During conveying, the telescopic rod 9 and spring 10 on the side wall of the moving plate 5 push the U-shaped part 11, so that the limiting roller 12 inside the U-shaped part 11 fits against the edge of the strip steel, and the edge of the strip steel is embedded in the annular groove 13 on the surface of the limiting roller 12. The elastic buffering effect of the spring 10 can adapt to the slight fluctuations in the conveying process of the strip steel. At the same time, the limiting roller 12 rotates synchronously with the conveying of the strip steel, and continuously limits the strip steel laterally without affecting the conveying efficiency. Finally, the strip steel is sent out through the square hole 3 at the other end of the ring plate 1, realizing stable conveying under deviation control.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
