[0002] With the rapid development of the steel industry, the requirements for steel quality are becoming increasingly stringent. Hot-rolled steel strip, as a crucial steel product, directly affects its shape and performance in subsequent processing and applications. With continuous advancements in science and technology and the promotion of industrial upgrading, traditional hot-rolled steel strip straightening methods are no longer sufficient to meet the demands of modern industry for efficiency, precision, and environmental friendliness. Therefore, it is necessary to design a hot-rolled steel strip straightening and straightening device.

[0003] To address this, patent CN216175466U discloses a straightening device for cold-rolled stainless steel strip, comprising a base, a drive motor, and a drive roller. The drive motor is installed at the bottom of the base and is bolted to the base. A rotating gear is installed on one side wall of the drive motor and is keyed to the drive motor. The advantages are: this invention, by setting up a drive motor, rotating gear, chain, driven gear, and drive roller, allows the drive motor to rotate the rotating gear, which in turn drives the driven gear, which in turn drives the drive roller. Because the chain and the driven gears on each drive roller are simultaneously and tightly connected, the rotation speed of the driven gears tends to be consistent, thus preventing uneven stress on the steel strip caused by different drive roller speeds, thereby improving the straightening effect of the device.

[0004] Although the above-mentioned straightening and straightening device for cold-rolled stainless steel strip can reduce the friction between the steel strip and the guide wheel during transportation, it is inconvenient to limit and correct the deviation of steel strips of different widths during use. Therefore, it is necessary to design a straightening and straightening device for hot-rolled steel strip. Utility Model Content

[0016] The present invention provides a straightening and straightening device for hot-rolled steel strip, the advantages of which are:

[0017] With the adjustment structure, the adjustment blocks can be moved in opposite directions or in reverse under the rotation of the screw, which makes it easy to change the distance between the limit rollers and adjust the limit distance of the limit rollers during use. It is suitable for steel strips of different widths and realizes that the device has the function of easily adjusting the distance of the limit rollers during use, thus improving the applicability of the hot-rolled steel strip straightening and straightening device during use.

[0018] By incorporating a downward pressing structure, the guide roller can be easily lowered under the lifting action of the hydraulic rod, facilitating contact between the bottom end of the guide roller and the top end of the steel strip to press and limit the steel strip. The rotational connection between the guide roller and the connecting frame facilitates the movement of the steel strip, reducing friction between the steel strip and the guide roller. This enables the device to easily press and limit the steel strip, improving the convenience of using the hot-rolled steel strip straightening and straightening device.

[0019] By incorporating a stretching component, the conveyor rollers can rotate at the same speed under the drive of the chain, which facilitates the uniform forward conveying and stretching of the steel strip, ensuring the stretching effect. This enables the device to perform stable stretching of the steel strip, thereby improving the working efficiency of the hot-rolled steel strip straightening and straightening device during use.

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.

[0027] Please see Figures 1-5 The present invention provides a straightening and straightening device for hot-rolled steel strip, including a base 1.

[0028] Reference Figure 1 , Figure 3 and Figure 4 A pressing structure 2 is fixed to one side of the top of the base 1. The pressing structure 2 includes a support rod 21, a support plate 22, a guide rod 23, a hydraulic rod 24, a connecting frame 25, and a guide roller 26. The support rods 21 are evenly fixed to the top of the base 1. The top of each support rod 21 is fixed with a support plate 22. The corners inside the support plate 22 are slidably connected with guide rods 23. The bottom of the support plate 22 is fixed with a hydraulic rod 24. The bottom of the hydraulic rod 24 is fixed with a connecting frame 25. The inner side of the connecting frame 25 is evenly rotatably connected with a guide roller 26.

[0029] When an external power source is connected and the hydraulic rod 24 is activated, the lifting and lowering of the hydraulic rod 24 will drive the lifting and lowering of the connecting frame 25. When the connecting frame 25 is lifted and lowered, it will drive the guide roller 26 to lift and lower. When the connecting frame 25 is lifted and lowered, the guide rod 23 and the support plate 22 are slidably connected, which can improve the stability of the connecting frame 25 during lifting and lowering.

[0030] Reference Figures 1-5 An adjustment structure 4 is provided on the top side of the base 1 away from the pressing structure 2. The adjustment structure 4 includes an adjustment groove 41 opened on the top side of the base 1 away from the pressing structure 2. The adjustment structure 4 also includes a servo motor 45 fixedly installed on the outer wall of one side of the base 1. Adjustment blocks 42 are provided on both sides inside the adjustment groove 41. A lead screw 43 is threadedly connected inside the adjustment block 42. A guide shaft 44 is provided on both sides of the lead screw 43. The threads at both ends of the adjustment block 42 are opposite. One end of the lead screw 43 extends into the interior of the base 1 and is rotatably connected to the base 1. The other end of the lead screw 43 extends into the exterior of the base 1 and is fixedly connected to the output end of the servo motor 45. The guide shaft 44 is slidably connected to the adjustment block 42. Both ends of the guide shaft 44 are fixedly connected to the inner wall of the base 1.

[0031] When the external power supply is connected, the servo motor 45 is started. The start of the servo motor 45 will drive the lead screw 43 to rotate. The rotation of the lead screw 43 can drive the adjusting blocks 42 to move closer or further apart inside the adjusting groove 41. This can drive the limiting rollers 3 to move closer or further apart, thereby achieving the purpose of adjusting the distance between the limiting rollers 3, which is convenient for limiting and correcting steel strips of different widths.

[0032] Reference Figure 1 , Figure 3 and Figure 4 Each adjusting block 42 has a limit roller 3 fixed at its top. The limit rollers 3 are symmetrically distributed on both sides of the base 1. The base 1 is equipped with a tensioning assembly 5. The tensioning assembly 5 includes a reserved groove 51, a conveying roller 52, a connecting toothed disc 53, a drive motor 54, and a chain 55. The reserved groove 51 is opened inside the base 1. The conveying roller 52 is evenly arranged inside the reserved groove 51. The connecting toothed disc 53 is evenly rotated and connected to the outer wall of the base 1. The outer side of the connecting toothed disc 53 is meshed with the chain 55. The drive motor 54 is fixedly installed on the outer wall of the base 1 near the connecting toothed disc 53. Both ends of the conveying roller 52 are rotatably connected to the inner wall of the base 1. The output end of the drive motor 54 is fixedly connected to one side of the connecting toothed disc 53. One end of the conveying roller 52 extends to the outer side of the base 1 and is fixedly connected to one side of the connecting toothed disc 53.

[0033] When the drive motor 54 is started, the rotation of the drive motor 54 will drive the connecting toothed disc 53 to rotate. The rotation of the connecting toothed disc 53 will drive the chain 55 to rotate. The rotation of the chain 55 will drive the other connecting toothed discs 53 to rotate together. When the connecting toothed disc 53 rotates, it can simultaneously drive the conveyor roller 52 to rotate, ensuring that the conveyor roller 52 rotates at the same speed. This facilitates the stretching of the steel strip and avoids deformation of the steel strip during stretching due to different rotation speeds of the conveyor roller 52.

[0034] Although the present invention 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 invention should be included within the protection scope of the present invention.
