Description

Technical Field

[0001] This utility model relates to the field of steel strip testing technology, specifically to a steel strip side flatness testing device. Background Technology

[0002] Steel strip, as a widely used basic material in industrial production, directly affects the performance and safety of subsequent products. The flatness of the steel strip's sides, as a key quality indicator, profoundly impacts product processing accuracy, assembly compatibility, and overall service life. The primary purpose of developing a steel strip and side flatness detection device is to accurately control product quality. Through high-precision sensors and intelligent algorithms, real-time and comprehensive detection of the steel strip's surface and sides can promptly detect flatness defects such as wavy lines and edge warping, ensuring that unqualified products do not enter the next stage and effectively improving the product yield. However, improving the adaptability of the detection device for steel strips of different widths and thicknesses is a pressing issue that needs to be addressed.

[0003] CN221549593U discloses a high-performance steel strip flatness testing device, comprising a base, rollers movably connected to both ends of the base via bearings, a conveyor belt movably connected to the rollers, a steel strip driven by the conveyor belt, a U-shaped bracket fixedly connected to the upper end of the base, a hydraulic cylinder fixedly connected to the center of the U-shaped bracket, and a mechanical frame fixedly connected to the front end of the piston rod of the hydraulic cylinder. This application, by setting up a flatness testing mechanism, eliminates the need for manual installation and fixing of the steel strip, allowing for direct online real-time detection of the steel strip during its transport process. This reduces operator workload, improves efficiency, minimizes human error, and enhances testing accuracy.

[0004] The problem with the above-mentioned high-performance steel strip flatness testing device is that:

[0005] I. Insufficient adaptability:

[0006] The comparison document uses fixed rollers and mechanical frame limits, which cannot dynamically adjust the limit range according to different steel strip widths, causing the steel strip to easily deviate during testing or not be compatible with multiple product specifications.

[0007] II. Limited testing methods:

[0008] Flatness detection using a mechanical clamping device driven by a single hydraulic cylinder can only determine defects by changes in pressure at fixed points. It has low sensitivity and cannot cover the entire side area of ​​the steel strip, making it easy to miss local warping or wavy lines. Utility Model Content

[0009] This invention proposes a steel strip side flatness detection device, which solves the problems of insufficient adaptability and single detection method of the existing technology for steel strip flatness testing.

[0010] The technical solution of this utility model is as follows: A steel strip side flatness detection device includes a conveying mechanism. A limiting guide component is provided on the top of the conveying mechanism. The limiting guide component includes two sets of bidirectional screws that rotate synchronously in the same direction. The two sets of bidirectional screws are respectively placed on the front and rear sides of the conveying mechanism. Each bidirectional screw has a sliding seat independently threaded at the opposite threads on both sides. A rotating shaft for centering and limiting the conveyed steel strip is rotatably connected to the middle of the sliding seat. An elastic clamping component is also provided on the top of the conveying mechanism between the two sets of bidirectional screws.

[0011] Preferably, the limiting and guiding assembly further includes two sets of brackets, which are fixedly connected to the conveying mechanism and correspond to the positions of each bidirectional screw, and each bidirectional screw is rotatably connected in each bracket.

[0012] Preferably, the limiting guide assembly further includes a forward and reverse motor, which is fixedly installed on the outside of the conveying mechanism, and the output end of the forward and reverse motor is fixedly connected to a bidirectional screw on one side.

[0013] Preferably, the limiting guide assembly further includes a first synchronous pulley and a second synchronous pulley. The first synchronous pulley is fixedly connected to a bidirectional screw on one side, and the second synchronous pulley is fixedly connected to a bidirectional screw on the other side. The limiting guide assembly also includes a synchronous belt, which is sleeved on the outside of the first synchronous pulley and the second synchronous pulley, and the synchronous belt is meshed with the first synchronous pulley and the second synchronous pulley for transmission.

[0014] Preferably, the elastic clamping assembly includes a support base, and sleeves are fixedly connected at equal intervals at the bottom of the support base.

[0015] Preferably, a sliding column is slidably connected inside the sleeve, a limiting block is fixedly connected to the side of the sliding column, the sliding column and the limiting block are integral and match the size of the inner groove of the sleeve, and a ball bearing is rotatably connected to the bottom of the sliding column.

[0016] Preferably, the elastic clamping assembly further includes a top rod, which is fixedly connected to the top of the sliding column. The elastic clamping assembly also includes a trigger button, which is fixedly installed inside the sleeve. The elastic clamping assembly further includes an audible and visual alarm unit, which is fixedly installed on the top of the sleeve. The audible and visual alarm unit is electrically connected to the trigger button.

[0017] Preferably, the elastic clamping assembly further includes a spring ring, which is disposed inside the sleeve. The lower end of the spring ring is fixedly connected to the sliding column, and the upper end of the spring ring is fixedly connected to the inner wall of the sleeve.

[0018] The beneficial effects of this utility model are as follows:

[0019] I. Bidirectional screw synchronous adjustment limit guide assembly

[0020] Innovation advantages:

[0021] By using two sets of bidirectional screws in conjunction with a synchronous belt drive, the slide can move synchronously in both directions, quickly adapting to steel belts of different widths, ensuring centering and limiting, and avoiding conveying deviation.

[0022] Improvement of the shortcomings of comparison:

[0023] This solves the compatibility problem caused by the fixed limit of the comparison document, and improves the versatility and stability of the detection device.

[0024] II. Multi-point elastic compression trigger alarm system

[0025] Innovation advantages:

[0026] The elastic clamping assembly has multiple inclined sleeves distributed in it, and multi-point real-time contact detection is achieved through sliding columns, spring rings and trigger buttons; when the steel strip is uneven, local lifting triggers an audible and visual alarm, which is highly sensitive and has a wide coverage.

[0027] Improvement of the shortcomings of comparison:

[0028] It overcomes the limitations of single-point detection in comparison documents, and can accurately capture local deformations on the sides, avoiding missed detections. Attached Figure Description

[0036] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0037] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 This utility model provides a technical solution: a steel strip side flatness detection device, including a conveying mechanism 1, a limiting guide component 2 is provided on the top of the conveying mechanism 1, the limiting guide component 2 includes two sets of bidirectional screws 23 that rotate synchronously in the same direction, the two sets of bidirectional screws 23 are respectively placed on the front and rear sides of the conveying mechanism 1, and each bidirectional screw 23 has a sliding seat 24 independently threaded at the opposite threads on both sides, and a rotating shaft 241 that can center and limit the conveying steel strip is rotatably connected in the middle of the sliding seat 24. An elastic pressing component 3 is also provided on the top of the conveying mechanism 1 between the two sets of bidirectional screws 23.

[0038] This design solves the problems of insufficient adaptability of existing technologies for testing the flatness of steel strips and the limited range of testing methods.

[0039] Please see Figure 1 and Figure 2 and Figure 3 The limiting guide assembly 2 also includes two sets of brackets 21. The brackets 21 are fixedly connected to the conveying mechanism 1 and correspond to the positions of each bidirectional screw 23. Each bidirectional screw 23 is rotatably connected in each bracket 21.

[0040] The limiting guide assembly 2 also includes a forward and reverse motor 22, which is fixedly installed on the outside of the conveying mechanism 1, and the output end of the forward and reverse motor 22 is fixedly connected to a bidirectional screw 23 on one side.

[0041] The limiting guide assembly 2 also includes a first synchronous pulley 251 and a second synchronous pulley 252. The first synchronous pulley 251 is fixedly connected to a bidirectional screw 23 on one side, and the second synchronous pulley 252 is fixedly connected to a bidirectional screw 23 on the other side. The limiting guide assembly 2 also includes a synchronous belt 25. The synchronous belt 25 is sleeved on the outside of the first synchronous pulley 251 and the second synchronous pulley 252, and the synchronous belt 25 is meshed with the first synchronous pulley 251 and the second synchronous pulley 252.

[0042] When the forward and reverse motor 22 is started to drive the bidirectional screw 23 at its output end to rotate, the first synchronous pulley 251 located on the side of the bidirectional screw 23 will rotate synchronously, and under the meshing transmission cooperation of the synchronous belt 25 and the second synchronous pulley 252, the bidirectional screw 23 located on the side of the second synchronous pulley 252 will also rotate synchronously.

[0043] When the two sets of bidirectional screws 23 rotate synchronously in the same direction, the slides 24 connected to the opposite threads on both sides of each bidirectional screw 23 will move synchronously towards each other until the rotating shaft 241 contacts the steel belt to be transported at the conveying mechanism 1. This design can limit the position of steel belts of various sizes within a range to avoid the steel belt from shifting position.

[0044] Please see Figure 4 and Figure 5 The elastic clamping assembly 3 includes a support base 31, and sleeves 32 are fixedly connected at equal intervals at the bottom of the support base 31.

[0045] A sliding column 33 is slidably connected inside the sleeve 32. A limiting block 332 is fixedly connected to the side of the sliding column 33. The sliding column 33 and the limiting block 332 are integral and match the size of the inner groove of the sleeve 32. A ball bearing 331 is rotatably connected to the bottom of the sliding column 33.

[0046] The elastic clamping assembly 3 also includes a push rod 34, which is fixedly connected to the top of the slide column 33. The elastic clamping assembly 3 also includes a trigger button 36, which is fixedly installed inside the sleeve 32. The elastic clamping assembly 3 also includes an audible and visual alarm unit 37, which is fixedly installed on the top of the sleeve 32. The audible and visual alarm unit 37 and the trigger button 36 are electrically connected.

[0047] The elastic clamping assembly 3 also includes a spring ring 35, which is located inside the sleeve 32. The lower end of the spring ring 35 is fixedly connected to the sliding column 33, and the upper end of the spring ring 35 is fixedly connected to the inner wall of the sleeve 32.

[0048] The sliding column 33 is elastically supported by the spring ring 35, which keeps the ball 331 at the bottom of the sliding column 33 in constant rolling contact with the surface of the steel strip. When there is an uneven section of the steel strip, the steel strip will drive the sliding column 33 to push upward in the sleeve 32. During the upward process, the push rod 34 will contact the trigger button 36, thereby triggering the audible and visual alarm unit 37. This design can be adapted to steel strips of various thicknesses and can detect flatness and quickly alarm.

[0049] The working principle and usage process of this utility model are as follows:

[0050] First, place the steel strip roll at the conveyor mechanism 1 and ensure that both sides of the steel strip correspond to the positions of the two sets of slide blocks 24 respectively;

[0051] Then, the forward and reverse motor 22 is started to drive the bidirectional screw 23 at its output end to rotate. The first synchronous pulley 251 located on the side of the bidirectional screw 23 will rotate synchronously. Under the meshing transmission cooperation of the synchronous belt 25 and the second synchronous pulley 252, the bidirectional screw 23 located on the side of the second synchronous pulley 252 will also rotate synchronously.

[0052] When the two sets of bidirectional screws 23 rotate synchronously in the same direction, the slides 24 threaded to the opposite threads on both sides of each bidirectional screw 23 will move synchronously towards each other until the rotating shaft 241 contacts the steel belt to be conveyed at the conveying mechanism 1. This design can limit the position of steel belts of various sizes within a range to avoid the steel belt from shifting position.

[0053] Specifically, the slide column 33 is elastically supported by the spring ring 35, which keeps the ball 331 at the bottom of the slide column 33 in constant rolling contact with the surface of the steel strip. When there is an uneven section in the steel strip, the steel strip will drive the slide column 33 to push upward in the sleeve 32. During the upward process, the push rod 34 will contact the trigger button 36, thereby triggering the audible and visual alarm unit 37. This design can be adapted to steel strips of various thicknesses and can detect flatness and quickly alarm.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
