Description

Technical Field

[0001] This utility model relates to the field of looper technology, specifically an adaptive adjustment looper device. Background Technology

[0002] In steel rolling production, there are often differences in rolling speed between rolling mills, which can easily lead to unstable raw material transportation and even cause shutdowns or equipment damage. To solve this problem, looper devices have emerged. By storing a certain amount of strip steel, they release or store steel when the speed fluctuates, playing a buffering and regulating role and ensuring the continuous and stable rolling process. They are key auxiliary devices for coordinating the rhythm of various equipment in the steel rolling production line.

[0003] Traditional looper devices have two major limitations in steel rolling: first, tension adjustment relies on a single power source (such as a cylinder), resulting in a delayed response to instantaneous fluctuations, which can easily lead to material deviation or breakage (e.g., CN215626789U); second, the impurity cleaning component is fixed, the collection frame is cumbersome to disassemble, and impurities are prone to secondary contamination (e.g., CN208731654U). This invention achieves real-time tension response through a two-stage adjustment component of 'spring fine adjustment + electric push rod coarse adjustment'; and solves the problem of inconvenient impurity collection through a cleaning component with 'locking groove - locking block' cooperation, thereby improving production stability and maintenance efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adaptive adjustment loop device, which realizes real-time tension response through a two-stage adjustment component of 'spring fine adjustment + electric push rod coarse adjustment'; and solves the problem of inconvenient impurity collection through a cleaning component of 'locking groove - locking block' cooperation, thereby improving production stability and maintenance efficiency.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: An adaptive adjusting looper device includes: a worktable, with two guide columns and two take-up columns mounted on the top of the worktable; a controller mounted on one side of the worktable; a take-up roller disposed between the two take-up columns; a guide roller disposed between the two guide columns; a small steel coil disposed between the take-up roller and the guide roller; a motor mounted on the top of the worktable, one side of which is driven by the take-up roller via a drive shaft; an adjusting component disposed inside the two guide columns for adaptively adjusting the height of the guide roller according to the material conveying conditions; the adjusting component includes: a lifting groove, a lifting block, a square slider, a square rod, and a spring; and a cleaning component disposed on the top of the worktable for cleaning small iron pieces from the surface of the small steel coil; the cleaning component includes: a cleaning brush, a clamping groove, and a collecting frame.

[0006] Preferably, an electric push rod is installed at the bottom of the workbench, and a U-shaped frame is connected to the top of the electric push rod. Each of the two guide columns has a lifting groove inside, and a limit rod is connected inside the lifting groove. A lifting block is installed inside each of the two lifting grooves, and one end of the limit rod passes through the lifting block. Both ends of the U-shaped frame are connected to the bottom of the two lifting blocks. An adaptation groove is opened inside the lifting block, and a square slider is installed inside the adaptation groove. A square rod is connected inside the adaptation groove, and one end of the square rod passes through the square slider. The inside of the square slider is slidably connected to the outside of the square rod. Springs are installed at the top and bottom of the square slider, and the square rod is located inside the springs. A connecting plate is connected to one side of each of the two square sliders, and a bearing is rotatably connected to one side of each connecting plate. Both ends of the guide roller are rotatably connected to one side of each of the two bearings.

[0007] Preferably, a fixed plate is connected to the top of the workbench, a cleaning brush is installed on the top of the fixed plate, a support block is connected to one side of the fixed plate, a locking groove is opened inside the support block, a locking block is provided on the top of the locking groove, a locking block that engages with the locking groove is provided on one side of the locking block, a collection frame is connected to the top of the locking block, a threaded rod is provided on one side of the locking block, one end of the threaded rod passes through the locking block and the support block and extends into the locking groove.

[0008] The beneficial effects of this utility model are: The advantage of this invention is that by using the lifting groove and spring in the adjustment component, the height of the guide roller can be automatically and in real time adjusted according to the tension changes of the small steel coil during the conveying process. This effectively buffers material fluctuations, maintains stable tension during the conveying process, and prevents the material from becoming too loose, too tight, or deviating, thereby improving production continuity and product quality.

[0009] Secondly, the cleaning brush, locking groove, and collection frame in the cleaning component can efficiently remove small iron pieces adhering to the surface of small steel coils, keeping the material surface clean and preventing small hard particles from being rolled in, which would cause the steel coil surface to become uneven and affect subsequent processing. At the same time, the design of the locking groove and locking block, combined with the threaded rod locking, makes the collection frame easy to install and disassemble, facilitating timely cleaning of collected impurities and improving equipment maintenance efficiency.

[0016] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0017] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-5 As shown, an adaptive adjusting looper device includes a worktable 1. Two guide columns 101 and two take-up columns 103 are mounted on the top of the worktable 1. A controller 102 is mounted on one side of the worktable 1. A take-up roller 104 is positioned between the two take-up columns 103, and a guide roller 105 is positioned between the two guide columns 101. A small steel coil 106 is positioned between the take-up roller 104 and the guide roller 105. A motor 604 is mounted on the top of the worktable 1. One side of the motor 604 is connected to the take-up roller 104 via a drive shaft. An adjusting component located inside the two guide columns 101 is used to adaptively adjust the height of the guide roller 105 according to the material conveying conditions. The adjusting component includes a lifting groove 201, a lifting block 3, a square slider 304, a square rod 302, and a spring 303. A cleaning component located on the top of the worktable 1 is used to clean small iron pieces from the surface of the small steel coil 106. The cleaning component includes a cleaning brush 501, a locking groove 6, and a collection frame 602.

[0019] The adjusting assembly, with its lifting groove 201, limiting rod 202, and spring 303, automatically and in real-time adjusts the height of the guide roller 105 according to the tension changes of the small steel coil 106 during conveying. This effectively buffers material fluctuations, maintains stable tension during conveying, and prevents material from becoming too loose, too tight, or misaligned, thereby improving production continuity and product quality. Secondly, the cleaning assembly, with its cleaning brush 501, locking groove 6, and collection frame 602, efficiently removes small iron pieces adhering to the surface of the small steel coil 106, keeping the material surface clean and preventing small hard particles from being rolled in, which could cause unevenness on the steel coil surface and affect subsequent processing. Simultaneously, the design of the locking groove 6 and the support block 502, combined with the threaded rod 601 for locking, makes the collection frame 602 easy to install and disassemble, facilitating timely cleaning of collected impurities and improving equipment maintenance efficiency.

[0020] The workbench 1 is equipped with an electric push rod 2 at its bottom. The top of the electric push rod 2 is connected to a U-shaped frame 203. The two guide columns 101 are each provided with a lifting groove 201. The lifting groove 201 is connected to a limit rod 202. The two lifting grooves 201 are each provided with a lifting block 3. One end of the limit rod 202 passes through the lifting block 3. The two ends of the U-shaped frame 203 are connected to the bottom of the two lifting blocks 3. The lifting block 3 is provided with an adaptation groove 301. The adaptation groove 301 is provided with a square slider 304. The adaptation groove 301 is connected to a square rod 302. One end of the square rod 302 passes through the square slider 304. The inside of the square slider 304 is slidably connected to the outside of the square rod 302. The top and bottom of the square slider 304 are provided with springs 303. The square rod 302 is located inside the springs 303. The two square sliders 304 are each connected to a connecting plate 4 on one side. The connecting plate 4 is rotatably connected to a bearing 401 on one side. The two ends of the guide roller 105 are rotatably connected to one side of the two bearings 401.

[0021] When the conveying tension of the small steel coil 106 changes instantaneously, the guide roller 105 drives the connecting plate 4 to move via the bearings 401 at both ends, pushing the square slider 304 to slide along the square rod 302 within the adaptation groove 301, compressing or releasing the spring 303 at the top or bottom of the square slider 304. The elastic deformation of the spring 303 within the spatial range of the adaptation groove 301 instantly absorbs tension fluctuations, achieving local adaptive buffering. When the tension continues to increase or decrease, causing the deformation of the spring 303 to exceed the buffering range of the adaptation groove 301, the controller 102 activates the electric push rod. 2 drives the U-shaped frame 203 to rise and fall, forcing the lifting block 3 to rise and fall along the lifting groove 201 as a whole, thereby adjusting the height position of the guide roller 105 over a wide range. When the tension is too high, the guide roller 105 is raised to relax the material, and when the tension is too low, the guide roller 105 is lowered to tighten the material. After the lifting and falling is completed, the spring 303 returns to the effective buffer zone to continue to cope with subsequent instantaneous fluctuations. Thus, the spring 303 provides rapid response and fine-tuning adaptation within a limited displacement, while the U-shaped frame 203 driven by the electric push rod 2 performs position adjustment. The two work together to achieve stable tension control under all working conditions.

[0022] The workbench 1 is connected to a fixed plate 5 at the top, and a cleaning brush 501 is installed on the top of the fixed plate 5. A support block 502 is connected to one side of the fixed plate 5. A locking groove 6 is opened inside the support block 502. A locking block 603 is set at the top of the locking groove 6. A locking block that engages with the locking groove 6 is set on one side of the locking block 603. A collection frame 602 is connected to the top of the locking block 603. A threaded rod 601 is set on one side of the locking block 603. One end of the threaded rod 601 passes through the locking block 603 and the support block 502 and extends into the locking groove 6.

[0023] When the small steel coil 106 passes the cleaning brush 501 on the top of the fixing plate 5, the bristles of the cleaning brush 501 make close contact with the surface of the steel coil, scraping off the attached small iron pieces and impurities. The removed impurities fall into the collection frame 602 below under the action of gravity. The collection frame 602 is inserted into the locking groove 6 of the support block 502 through the locking block 603 at the top. The locking block 603 on the side and the inclined structure of the inner wall of the locking groove 6 form the initial positioning. Then, the threaded rod 601 is tightened so that its end presses against the inner wall of the locking groove 6, generating a locking force to fix the locking block 603 and the collection frame 602. When it is necessary to clean the impurities, the threaded rod 601 is loosened to release the tightening force, and the collection frame 602 together with the locking block 603 can be vertically pulled out from the locking groove 6 to achieve quick disassembly and maintenance.

[0024] Working principle: When the conveying tension of the small steel coil 106 changes instantaneously, the guide roller 105 drives the connecting plate 4 to move via the bearings 401 at both ends, pushing the square slider 304 to slide along the square rod 302 within the adaptation groove 301, compressing or releasing the spring 303 at the top or bottom of the square slider 304. The elastic deformation of the spring 303 within the spatial range of the adaptation groove 301 instantly absorbs tension fluctuations, achieving local adaptive buffering. When the tension continues to increase or decrease, causing the deformation of the spring 303 to exceed the buffering range of the adaptation groove 301, the controller 102 activates the electric push rod. 2 drives the U-shaped frame 203 to rise and fall, forcing the lifting block 3 to rise and fall along the lifting groove 201 as a whole, thereby adjusting the height position of the guide roller 105 over a wide range. When the tension is too high, the guide roller 105 is raised to relax the material, and when the tension is too low, the guide roller 105 is lowered to tighten the material. After the lifting and falling is completed, the spring 303 returns to the effective buffer zone to continue to cope with subsequent instantaneous fluctuations. Thus, the spring 303 provides rapid response and fine-tuning adaptation within a limited displacement, while the U-shaped frame 203 driven by the electric push rod 2 performs position adjustment. The two work together to achieve stable tension control under all working conditions.

[0025] When the small steel coil 106 passes the cleaning brush 501 on the top of the fixing plate 5, the bristles of the cleaning brush 501 make close contact with the surface of the steel coil, scraping off the attached small iron pieces and impurities. The removed impurities fall into the collection frame 602 below under the action of gravity. The collection frame 602 is inserted into the locking groove 6 of the support block 502 through the locking block 603 at the top. The locking block 603 on the side and the inclined structure of the inner wall of the locking groove 6 form the initial positioning. Then, the threaded rod 601 is tightened so that its end presses against the inner wall of the locking groove 6, generating a locking force to fix the locking block 603 and the collection frame 602. When it is necessary to clean the impurities, the threaded rod 601 is loosened to release the tightening force, and the collection frame 602 together with the locking block 603 can be vertically pulled out from the locking groove 6 to achieve quick disassembly and maintenance.

[0026] In addition, all electrical components mentioned in the article are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail in the article.
