Technical Field
[0001] This utility model relates to the technical field of steel plate straightening machines, and in particular to a structure of a multi-roller steel plate straightening machine. Background Technology
[0002] Multi-roll steel plate straightening machine is a metal sheet processing equipment specially designed to eliminate unevenness problems such as internal stress, warping, and wave deformation generated during the rolling, cutting, transportation, or processing of steel plates. Its core principle is to straighten the steel plate through multiple sets of working rolls to ultimately achieve high flatness requirements.
[0003] A multi-roller steel plate straightening machine, disclosed on the Chinese Patent Network (publication number CN208758374U), includes a machine housing, a control box, a locking cover plate, and a lifting screw. A glass window is fixedly connected to the front of the machine housing, and the control box is welded to the front of the machine housing, positioned directly below the glass window. Two sets of first and second straightening rollers are movably connected to the inner wall of the machine housing. The two sets of first straightening rollers are arranged in a staggered, vertical arrangement, with the second straightening roller positioned between the upper first straightening rollers. The first straightening rollers include an adhesive layer and an anti-wear layer. This design solves the problem of straightening machines being unable to differentiate between steel plates of different thicknesses, thus effectively improving the quality of steel plate straightening. It also eliminates the inconvenience of frequently replacing worn straightening rollers during long-term use, effectively improving the ease of use of the straightening machine. Furthermore, it eliminates the problem of the straightening machine easily running dry, thus effectively improving its working efficiency.
[0004] The following problems also exist in this solution: Although the device can correct steel plates of different thicknesses when correcting steel plates, it does not have a limiting structure. The correcting roller will deviate when conveying and correcting the steel plate, which reduces the stability of the steel plate correction and has certain drawbacks.
[0005] Therefore, in order to solve the above problems, this utility model provides a multi-roller steel plate straightening machine structure. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1 - Figure 4 The present invention will be described in further detail below.
[0021] A multi-roller steel plate straightening machine structure, referring to Figure 1 - Figure 4The system includes an operating platform 1. Several conveying rollers 2 are installed at equal intervals between the top two side walls of the operating platform 1. Support frames 3 are installed at the four corners of the top of the operating platform 1. A top plate 4 is installed on the top of the support frames 3. An electric telescopic rod 5 is installed on the top of the top plate 4. A movable plate 6 is installed after the bottom movable end of the electric telescopic rod 5 passes through the top plate 4. Several pressure rollers 7 are installed at equal intervals between the bottom two side walls of the movable plate 6. A fixed seat 8 is installed between the bottom support legs of the operating platform 1. Slide rails 9 are symmetrically installed at both ends of the top of the fixed seat 8. A slider 10 is installed on the slide rail 9. A support rod 11 is installed on the top of the slider 10. A support plate 12 is installed at one end of the top of the support rod 11. Several limiting rollers 13 are installed at equal intervals along the length direction on the outer side of the support plate 12.
[0022] Reference Figure 1 - Figure 3 One end of the conveying roller 2 has a rotating shaft that passes through the inside of the operating table 1 and is fitted with a sprocket 14. A chain 15 is installed on the outside of the sprockets 14. A drive motor 16 is installed on the outside of the operating table 1. The output shaft of the drive motor 16 passes through the inside of the operating table 1 and is connected to one of the sprockets 14. When the drive motor 16 starts, its output shaft drives the sprocket 14 connected to it to rotate. The sprocket 14 drives the other sprockets 14 to rotate synchronously through the chain 15, so that all the conveying rollers 2 rotate synchronously and achieve stable conveying of steel plates.
[0023] Reference Figure 1 - Figure 4 A servo motor 17 is embedded in the top of the fixed base 8. A rotating rod 18 is mounted on the output shaft of the servo motor 17. Connecting rods 19 are symmetrically mounted at both ends of the rotating rod 18. The end of the connecting rod 19 away from the rotating rod 18 is connected to the outside of the slider 10. Both ends of the connecting rod 19 are rotatably connected to the rotating rod 18 and the slider 10. The bottom of the limiting roller 13 does not contact the conveying roller 2. After the servo motor 17 is started, its output shaft drives the rotating rod 18 to rotate. The rotating rod 18 drives the slider 10 to move on the slide rail 9 through the connecting rod 19. The slider 10 drives the support rod 11 and the support plate 12 to move, thereby making the limiting roller 13 move horizontally. The limiting roller 13 moves in the direction of the slide rail 9 and is used to limit the steel plate to prevent it from deviating during the conveying process. The position of the limiting roller 13 is adjusted according to the width of the steel plate to ensure that the steel plate is always in the correct conveying position. The fixing frame 20 is symmetrically installed on the top of the fixing seat 8 and on both sides of the slide rail 9. The outer ring surface of the fixing frame 20 is slidably connected to the inside of the slider 10. When the slider 10 moves on the slide rail 9, the sliding connection between the fixing frame 20 and the inside of the slider 10 ensures the smoothness and straightness of the slider 10's movement, preventing the slider 10 from shaking or deviating from the track during the movement, thereby ensuring that the limiting roller 13 can move accurately to effectively limit the steel plate.
[0024] Reference Figure 1 - Figure 2 Limiting rods 21 are installed at the four corners of the top of the movable plate 6. One end of the limiting rod 21 passes through the top plate 4 and extends above it. The outer ring surface of the limiting rod 21 is slidably connected to the inside of the top plate 4. The electric telescopic rod 5 can drive the movable plate 6 to move up and down, thereby causing the pressure roller 7 to press down. The electric telescopic rod 5 drives the movable plate 6 to move down. The pressure roller 7 applies pressure to the steel plate and works with the conveying roller 2 to make the steel plate level during the conveying process. By adjusting the extension and retraction of the electric telescopic rod 5, the pressure of the pressure roller 7 on the steel plate can be controlled to adapt to the leveling requirements of steel plates of different thicknesses. The limiting rods 21 play a role in restricting the movement direction of the movable plate 6 and preventing its rotation, ensuring that the pressure roller 7 can accurately press down on the steel plate vertically and ensure the leveling effect.
[0025] Reference Figure 1 - Figure 2 A loading platform 22 is installed at one end of the outside of the operating platform 1, and a unloading platform 23 is installed at the other end of the operating platform 1 away from the loading platform 22. The loading platform 22 is used to smoothly transport the steel plate to be leveled onto the conveying roller 2 on the operating platform 1, so that the steel plate can enter the leveling machine for leveling operation. The unloading platform 23 is used to receive the leveled steel plate conveyed from the operating platform 1, so that the steel plate can leave the leveling machine smoothly.
[0026] The implementation principle of the multi-roller steel plate straightening machine structure of this utility model embodiment is as follows: When the device is used, after the drive motor 16 starts, its output shaft drives the sprocket 14 connected to it to rotate. The sprocket 14 drives other sprockets 14 to rotate synchronously through the chain 15, thereby making all the conveying rollers 2 rotate synchronously and realizing the stable conveying of the steel plate. The electric telescopic rod 5 can drive the movable plate 6 to move up and down, thereby causing the pressure roller 7 to press down. The electric telescopic rod 5 drives the movable plate 6 to move down, and the pressure roller 7 applies pressure to the steel plate in conjunction with the conveying rollers 2 so that the steel plate is leveled during the conveying process. By adjusting the telescopic amount of the electric telescopic rod 5, the pressure of the pressure roller 7 on the steel plate can be controlled to adapt to the leveling requirements of steel plates of different thicknesses. The limiting rod 21 plays a role in limiting the movement direction of the movable plate 6 and preventing its rotation, ensuring that the pressure roller 7 can accurately press the steel plate vertically and ensure the leveling effect. After the servo motor 17 starts, its output shaft drives the rotating rod 18 to rotate. The rotating rod 18 is connected to the connecting rod 19. The slider 10 moves along the slide rail 9, which in turn moves the support rod 11 and the support plate 12, causing the limiting roller 13 to move horizontally. The limiting roller 13 is used to limit the steel plate and prevent it from shifting during transport. The position of the limiting roller 13 is adjusted according to the width of the steel plate to ensure that the steel plate is always in the correct transport position. When the slider 10 moves along the slide rail 9, the sliding connection between the fixed frame 20 and the inside of the slider 10 ensures the smoothness and straightness of the slider 10's movement, preventing the slider 10 from shaking or deviating from the track during movement. This ensures that the limiting roller 13 can move accurately and effectively limit the steel plate. The loading platform 22 is used to smoothly transport the steel plate to be leveled onto the conveying roller 2 on the operating platform 1, making it convenient for the steel plate to enter the leveling machine for leveling operations. The unloading platform 23 is used to receive the leveled steel plate transported from the operating platform 1, allowing the steel plate to leave the leveling machine smoothly. This makes the operation convenient and more practical.
