Technical Field
[0001] This utility model relates to the field of cold-rolled strip steel production technology, and in particular to a leveling device for cold-rolled strip steel production. Background Technology
[0002] In the current strip steel rolling process, the strip steel coil is placed on the uncoiling machine for uncoiling. The guide plate on the rolling mill first extends and then rises to uncoil the strip steel coil on the uncoiling machine. The strip steel coil gradually unfolds under the guidance of the guide plate and is initially leveled by a leveling device to ensure that the surface of the strip steel is flat and wrinkle-free. Subsequently, the strip steel enters subsequent processing stages such as rolling to further improve product quality.
[0003] However, in actual production, during the process of leveling the strip steel, workers need to use auxiliary tools such as long poles to manually tap the bulges of the conveyed strip steel to help flatten it and make it easier for the strip steel to pass through the leveling rollers for leveling. This reduces the safety of workers and is time-consuming and labor-intensive. Summary of the Invention
[0004] In view of this, the purpose of this utility model is to propose a leveling device for cold-rolled strip steel production, so as to solve the problem of time-consuming and labor-intensive operations such as frequent tapping by workers in the strip steel leveling process.
[0005] To achieve the above objectives, this utility model provides a leveling device for cold-rolled strip steel production, comprising a machine body, on which a clamping member is provided, the clamping member including two clamping rollers arranged vertically, a leveling group located on the machine body on one side of the clamping member, the leveling group including two leveling rollers arranged vertically, a through-hole for strip steel to pass through between the two leveling rollers, a conveyor platform located on the machine body between the clamping member and the leveling group, a conveyor belt for strip steel being provided on the conveyor platform, and an inclined guide plate being provided between the conveyor platform and the leveling rollers, the height of the inclined guide plate near the conveyor platform not exceeding the height of the upper surface of the conveyor belt, and the height of the inclined guide plate near the conveyor platform being lower than the height of the other end of the inclined guide plate.
[0006] Optionally, the height of the other end of the inclined guide plate is not lower than the height of the upper end face of the flattening roller arranged below, and the height of the other end of the inclined guide plate is lower than the height of the lower end face of the flattening roller arranged above.
[0007] Optionally, the leveling group is provided in multiple groups, and the multiple groups of leveling groups are arranged at equal intervals. The spacing between the through-holes of two leveling rollers arranged vertically in the leveling group gradually decreases with the transport direction of the strip steel.
[0008] Optionally, a bracket is provided on one side of the transport platform and mounted on the machine body. A swing plate located above the conveyor belt is rotatably connected to the bracket. One end of the swing plate is rotatably connected to the bracket via a rotating shaft. A swinging component for controlling the swinging of the swing plate is provided on the bracket.
[0009] Optionally, the swinging component includes a drive cylinder rotatably mounted on the bracket, with the telescopic end of the drive cylinder hinged to the middle of the swing plate.
[0010] Optionally, a pressure plate is hinged to the other end of the swing plate, and a traction rod for pulling the pressure plate is fixedly connected to the middle of the swing plate, with the lower end of the traction rod connected to the upper end of the pressure plate.
[0011] Optionally, a plurality of pressure rollers are rotatably connected to the lower end face of the pressure plate.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a leveling device for cold-rolled strip steel production. After the uncoiled strip steel arrives at one side of the clamping rollers on the clamping member, the two clamping rollers on the clamping member clamp and transport the strip steel towards the leveling group. The strip steel first arrives at the transport table, where the conveyor belt also transports the strip steel, preventing the strip steel end from remaining on the machine body. Under the oblique guidance of the inclined guide plate, the strip steel end arrives between the upper and lower leveling rollers. The inclined guide plate prevents the strip steel from remaining at the entrance of the leveling group for an extended period. The leveling rollers on the leveling group facilitate the improvement of the strip steel's shape, adjust its surface finish and mechanical properties, making the strip steel easier for subsequent processing. The conveyor belt and its configuration ensure smooth transport of the strip steel end to the leveling group. During the transport of the strip steel end before leveling, the frequency of workers striking the strip steel is reduced, or even eliminated altogether, improving worker safety, reducing product-related injuries, increasing production safety, avoiding accidents caused by human error, and improving production efficiency.

[0019] like Figures 1 to 2 As shown, a leveling device for cold-rolled strip steel production includes a machine body 1. A clamping component is provided on the machine body 1. The clamping component includes two clamping rollers 2 arranged vertically. The ends of the clamping rollers 2 are connected to the machine body 1 through a first support frame 3. A leveling group is provided on one side of the clamping component and located on the machine body 1. The leveling group includes two leveling rollers 8 arranged vertically. A through-hole for strip steel to pass through is provided between the two leveling rollers 8. The ends of the leveling rollers 8 are connected to the machine body 1 through a second support frame 7. A transport platform 4 is provided on the machine body 1 between the clamping component and the leveling group. A conveyor belt 5 for strip steel is provided on the transport platform 4. An inclined guide plate 6 is provided between the transport platform 4 and the leveling rollers 8. The height of the inclined guide plate 6 near the transport platform 4 is not higher than the height of the upper surface of the conveyor belt 5, and the height of the inclined guide plate 6 near the transport platform 4 is lower than the height of the other end of the inclined guide plate 6.
[0020] After the uncoiled strip arrives at one side of the clamping roller 2 on the clamping device, the two clamping rollers 2, set at the top and bottom on the clamping device, clamp and transport the strip towards the leveling group. The strip first arrives at the transport table 4, where the conveyor belt 5 also transports the strip to prevent the end of the strip from getting stuck on the machine body 1. Under the oblique guidance of the inclined guide plate 6, the end of the strip arrives between the upper and lower leveling rollers 8. The inclined guide plate 6 is set to prevent the strip from getting stuck at the entrance of the leveling group for a long time. The leveling rollers 8 on the leveling group help to improve the strip shape, adjust the surface finish and mechanical properties of the strip, making the strip easier to process in subsequent steps. The conveyor belt 5 and its arrangement can smoothly transport the end of the strip to the leveling group. During the transport of the strip before leveling, the frequency of workers hitting the strip is reduced, or even eliminated, improving worker safety, reducing product-related injuries, improving production safety, avoiding accidents caused by human error, and improving production efficiency.
[0021] The height of the other end of the inclined guide plate 6 is not lower than the height of the upper end face of the lower leveling roller 8, and the height of the other end of the inclined guide plate 6 is lower than the height of the lower end face of the upper leveling roller 8. This facilitates the transport of strip steel to the leveling group for leveling treatment and improves processing efficiency.
[0022] The leveling group is provided in multiple groups, which are arranged at equal intervals. The spacing between the through holes of the two leveling rollers 8 arranged vertically in the leveling group gradually decreases with the transport direction of the strip steel. That is, the spacing of the through holes closer to the transport table 4 is greater than the spacing of the through holes farther away from the transport table 4. The leveling group facilitates the slight rolling of the strip steel, adjusts the surface finish and mechanical properties of the strip steel, and makes the strip steel easier to process in subsequent processes.
[0023] A bracket 9 is provided on one side of the transport platform 4 and mounted on the machine body 1. A swing plate 11 located above the conveyor belt 5 is rotatably connected to the bracket 9. One end of the swing plate 11 is rotatably connected to the bracket 9 via a rotating shaft. A swinging component is provided on the bracket 9 to control the swinging of the swing plate 11. The swinging component controls the swinging of the swing plate 11 to flatten the strip steel on the transport platform 4, making the strip steel easier to process in subsequent steps.
[0024] The swinging component includes a drive cylinder 10 rotatably mounted on the bracket 9. The telescopic end of the drive cylinder 10 is hinged to the middle of the swing plate 11. When the drive cylinder 10 starts to extend, it drives the swing plate 11 to swing downward, so that the lower end of the swing plate 11 can flatten the strip steel transported on the conveyor belt 5, reduce the curl of the strip steel, and improve the efficiency of subsequent strip steel flattening.
[0025] The aforementioned oscillating component can be replaced. The oscillating component can be a drive motor installed on the bracket 9. The output end of the drive motor is connected to the rotating shaft. When the drive motor is started, the oscillating plate 11 is driven to swing downward through the rotation of the rotating shaft. This facilitates the lower end of the oscillating plate 11 to flatten the strip steel transported on the conveyor belt 5, reduce the curl of the strip steel, and improve the efficiency of subsequent strip steel flattening processing.
[0026] The other end of the swing plate 11 is hinged to a pressure plate 12. A traction rod 14 for pulling the pressure plate 12 is fixedly connected to the middle of the swing plate 11. The lower end of the traction rod 14 is connected to the upper end of the pressure plate 12. The traction rod 14 is located below the drive cylinder 10. Multiple pressure rollers 13 are rotatably connected to the lower end face of the pressure plate 12. The pressure plate 12 flattens the strip steel transported on the conveyor belt 5 at the lower end of the swing plate 11, and flattens local areas of the strip steel to increase the flattening range of the strip steel. The pressure rollers 13 roll and flatten the strip steel to reduce the coiling degree of the strip steel, which facilitates the subsequent flattening treatment of the strip steel.
