Abstract
Description
Technical Field
[0001] This utility model relates to the field of alignment device technology, and more particularly to a steel strip alignment device. Background Technology
[0002] Steel strip, as an important industrial raw material, is widely used in many fields such as machinery manufacturing, automobiles, and electronics. Its processing accuracy has a decisive impact on the quality of subsequent products, and steel strip centering devices emerged in this context. Early steel strip processing was small-scale and the processes were relatively simple, with centering largely relying on manual labor. Workers manually adjusted the position of the steel strip using visual observation and simple measuring tools to ensure its centered position within the processing equipment. This primitive centering method was not only extremely inefficient but also highly dependent on worker experience and subjective judgment, making it difficult to guarantee centering accuracy. Problems such as steel strip misalignment and twisting frequently occurred, resulting in inconsistent product quality and severely hindering the improvement of production efficiency and product quality.
[0003] However, traditional steel strip alignment devices are simple in structure and limited in function, often relying on manual adjustment. Operators must adjust the alignment position using mechanical bolts and other components based on experience, which is not only cumbersome and inefficient but also makes it difficult to guarantee alignment accuracy. This can easily lead to problems such as strip deviation and twisting during transmission, affecting the normal operation of subsequent processing steps. Furthermore, the tension adjustment system and alignment system of traditional devices are independent, lacking an effective linkage mechanism. When the steel strip tension changes, the alignment position changes accordingly, and adjustments to the alignment position can cause tension fluctuations, leading to mutual interference and making stable coordinated operation difficult. In addition, traditional devices are difficult to adapt to steel strips of different specifications and materials. When production tasks change, the equipment requires extensive and complex parameter adjustments and mechanical modifications, which are not only time-consuming and labor-intensive but also increase production costs. This fails to meet the demands of modern industrial production for efficient, precise, and flexible processing, and therefore requires improvement. Utility Model Content
[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.
[0005] This utility model adopts the following technical solution: a steel strip centering device, including a support frame one, a support frame two fixedly installed at the top of the support frame one, a fixed frame one placed at the top of the support frame two, a steel strip coil sleeved inside the fixed frame one, a groove formed on the surface of the support frame one, a moving rod one sleeved inside the groove, a rack one fixedly installed on the surface of the moving rod one, a fixed frame two fixedly installed at the top of the support frame one, a worm gear one sleeved inside the fixed frame two, a handwheel fixedly installed at one end of the worm gear one, a rotating rod sleeved inside the fixed frame two, a worm wheel one fixedly installed at one end of the rotating rod, a gear one fixedly installed at the other end of the rotating rod, and a fixed frame fixedly installed at the top of the moving rod one. A worm gear two is fitted inside the fixed frame, with a rotating block fixedly installed at one end of the worm gear two. A worm wheel two is fitted inside the fixed frame, with a gear two fixedly installed at the rear end of the worm wheel two. A gear ring is fitted inside the fixed frame. A gear three is fitted inside the fixed frame, with a rotating plate fixedly installed on the surface of the gear three. A fixed column is fixedly installed on the surface of the rotating plate. A movable frame is fitted inside the fixed frame, with a movable column fixedly installed at the bottom end of the movable frame. A fitted frame is fixedly installed at the bottom end of the movable column. A pressure cylinder is fitted inside the fitted frame. A spring one is fitted inside the fixed frame. A movable rod two is fitted inside the fixed frame, with a spring two fitted on the outer surface of the movable rod two. A clamping plate is fixedly installed at one end of the movable rod two.
[0006] Preferably, there are two sets of springs and moving rods, symmetrically distributed at the rear end of the clamping plate and inside the fixed frame. One end of each spring is connected and fixed to the rear surface of the clamping plate, and the other end is connected and fixed to the surface of the fixed frame. Here, the two sets of springs and moving rods symmetrically distributed at the rear end of the clamping plate and inside the fixed frame provide uniform elastic support force for the clamping plate.
[0007] Preferably, there are two sets of clamping plates symmetrically distributed inside the fixed frame. The surfaces of the clamping plates are in contact with both sides of the steel strip, the surface of the pressure cylinder is in contact with the upper and lower ends of the steel strip, and the surface of the first worm gear meshes with the surface of the first worm. Here, the two sets of symmetrically distributed clamping plates are in contact with both sides of the steel strip, and together with the pressure cylinders in contact with the upper and lower ends of the steel strip, the steel strip is positioned and fixed in all directions from the horizontal and vertical directions, ensuring that the steel strip is always in the center position during operation and effectively preventing the steel strip from deviating.
[0008] Preferably, there are two sets of the first movable rod, the fixed frame, and the first rack, with the surfaces of both sets of the first rack meshing with the surface of the first gear. The surface of the second worm gear meshes with the surface of the second worm, and the surface of the second gear meshes with the surface of the gear ring. Here, the two sets of the first movable rod, the fixed frame, and the first rack, in conjunction with the first gear, achieve stable power transmission and symmetrical adjustment, allowing the fixed frame to move smoothly and ensuring the accuracy and consistency of the steel belt's lateral alignment.
[0009] Preferably, there are two sets of gears three, symmetrically distributed inside the fixed frame. The surface of each gear three meshes with the surface of the gear ring. There are also two sets of springs two, symmetrically distributed on the surfaces of the fixed frame and the moving frame. One end of each spring two is connected and fixed to the inner surface of the fixed frame, and the other end is connected and fixed to the surface of the moving frame. The fixing post is fitted inside the moving frame. Here, the two sets of symmetrically distributed gears three mesh with the gear ring, ensuring uniform force distribution when the rotating plate rotates, driving the moving frame to move smoothly up and down, making the pressure of the pressure cylinder on the upper and lower ends of the steel strip consistent, and improving the longitudinal alignment effect.
[0010] Preferably, a fixing plate is fixedly mounted on the surface of the fixing frame one. A sliding rod is sleeved inside the fixing plate, and a spring three is sleeved on the outer surface of the sliding rod. A protective frame is fixedly mounted on the top of the sliding rod. Sliding rods are sleeved inside both sides of the protective frame, and spring four is sleeved on the outer surface of the sliding rods. A stop plate is fixedly mounted on one end of the sliding rod, and a roller is sleeved inside the stop plate. Here, the structure composed of the fixing plate, sliding rod, and spring three allows the protective frame to move elastically up and down. The spring three in its initial contracted state provides upward support force for the protective frame.
[0011] Preferably, the rollers are arranged in multiple sets in an array inside the stop plate, with the surface of each roller in contact with the side surface of the steel strip coil. The springs and slide rods are arranged in four sets, symmetrically distributed at the rear end of the stop plate and inside the protective frame. The protective frame is N-shaped, with its bottom surface in contact with the surface of the steel strip coil. Here, the multiple arrayed rollers are in full contact with the side of the steel strip coil, effectively dispersing contact pressure, reducing wear, and lowering the resistance during the rotation of the steel strip coil.
[0012] Preferably, one end of spring four is fixedly connected to the surface of the protective frame, and the other end of spring four is fixedly connected to the rear end surface of the abutment plate. One end of spring three is fixedly connected to the bottom end surface of the fixed plate, and the other end of spring three is fixedly connected to the surface of the sliding rod. The initial state of spring three is a contracted state. Here, spring four connects the protective frame and the abutment plate, providing elastic cushioning for the abutment plate, so that the abutment plate can both tightly abut against the steel strip coil and protect the surface of the steel strip coil when subjected to impact.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a support frame one, a support frame two, and a fixed frame one structure, during alignment operation, rotating the rotating block enables precise longitudinal adjustment of the steel strip by the pressure cylinder through the precision transmission of the worm gear and gear ring. The adaptive structure composed of two sets of springs two and the clamping plate can closely fit steel strips of different sizes, eliminating the need for repeated manual calibration. Regarding tension adjustment, rotating the handwheel drives gear one and rack one in linkage, causing the two fixed frames on both sides to move synchronously, achieving precise tension control. While adjusting the tension, it automatically maintains the alignment of the steel strip, avoiding mutual interference. By setting up multiple structures to coordinate movement, it can quickly adapt to steel strips of different specifications and materials, allowing for switching production tasks without complex modifications, greatly improving production efficiency and equipment applicability.
[0014] 2. In this utility model, by setting up a structure consisting of a fixed plate, a sliding rod, a third spring, a protective frame, a sliding rod, a fourth spring, a stop plate, and rollers, the structure composed of the fixed plate, sliding rod, and third spring allows the protective frame to move elastically up and down during equipment use. The third spring, in its initial contracted state, provides upward support for the protective frame. When the steel strip roll is installed or running, the protective frame can adaptively adjust its height. The structure on both sides of the protective frame, composed of sliding rods, fourth springs, a stop plate, and rollers, elastically abuts against the side ends of the steel strip roll. Multiple arrayed rollers fit snugly against the side ends of the steel strip roll, reducing friction. While protecting the edges of the steel strip roll, this structure also helps maintain the steel strip roll in a stable position, preventing lateral displacement during rotation and providing good initial conditions for steel strip alignment.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0019] Example 1 Please see Figures 1-5 , Figures 7-8This utility model provides a technical solution: a steel strip centering device, including a support frame 1, a support frame 2 fixedly installed at the top of the support frame 1, a fixing frame 3 placed at the top of the support frame 2, a steel strip coil 4 sleeved inside the fixing frame 3, a groove 5 formed on the surface of the support frame 1, a moving rod 6 sleeved inside the groove 5, a rack 7 fixedly installed on the surface of the moving rod 6, a fixing frame 8 fixedly installed at the top of the support frame 1, a worm gear 9 sleeved inside the fixing frame 8, a handwheel 10 fixedly installed at one end of the worm gear 9, and a rotating rod 11 sleeved inside the fixing frame 8. A worm gear 12 is fixedly installed at one end of a rotating rod 11, and a gear 13 is fixedly installed at the other end of a moving rod 16. A fixed frame 14 is fixedly installed at the top of the moving rod 16. A worm gear 15 is fitted inside the fixed frame 14. A rotating block 16 is fixedly installed at one end of the worm gear 15. A worm gear 17 is fitted inside the fixed frame 14. A gear 18 is fixedly installed at the rear end of the worm gear 17. A gear ring 19 is fitted inside the fixed frame 14. A gear 20 is fitted inside the fixed frame 14. A rotating plate 21 is fixedly installed on the surface of the gear 20. A fixed post 22 is fixedly installed on the surface of the rotating plate 21. A fixed post 22 is fitted inside the fixed frame 14. A movable frame 23 is provided, with a movable column 24 fixedly installed at the bottom of the movable frame 23. A sleeve frame 25 is fixedly installed at the bottom of the movable column 24. A pressure cylinder 26 is sleeved inside the sleeve frame 25. A spring 27 is sleeved inside the fixed frame 14. A movable rod 28 is sleeved inside the fixed frame 14. A spring 29 is sleeved on the outer surface of the movable rod 28. A clamping plate 30 is fixedly installed at one end of the movable rod 28. When centering is required, one end of the steel strip coil 4 is first inserted through the fixed frame 14. Then, the rotating block 16 is rotated, which drives the worm gear 15 to rotate. The worm gear 15 meshes with the worm wheel 17, causing the worm to rotate. Gear 18 at the rear end of wheel 2 17 rotates, meshing with gear ring 19. Gear ring 19 then drives gear 3 20 to rotate, and the rotating plate 21 on the surface of gear 3 20 rotates accordingly. The fixed column 22 on the rotating plate 21 drives the moving frame 23 to move downward. The moving frame 23 drives the sleeve frame 25 and pressure cylinder 26 to move downward through the moving column 24, thus longitudinally pressing and adjusting the position of the steel strip, and simultaneously performing centering treatment. In addition, during the adjustment process, spring 1 27 provides buffering to ensure the smoothness of the adjustment. At the same time, through two sets of spring 2 29 and clamping plate 30, it can adapt to steel strips of different sizes for centering treatment.
[0020] Please see Figures 1-8There are two sets of springs 29 and moving rods 28, which are symmetrically distributed at the rear end of the clamping plate 30 and inside the fixed frame 14. One end of spring 29 is connected and fixed to the rear end surface of the clamping plate 30, and the other end of spring 29 is connected and fixed to the surface of the fixed frame 14. There are two sets of clamping plates 30, which are symmetrically distributed inside the fixed frame 14. The surface of the clamping plate 30 is in contact with both sides of the steel strip. The surface of the pressure cylinder 26 is in contact with the upper and lower end surfaces of the steel strip. The surface of the worm gear 12 meshes with the surface of the worm 9. Moving rod 6 and fixed frame 14 There are two sets of racks 7, and the surfaces of both sets of racks 7 mesh with the surfaces of gears 13. The surface of worm gear 17 meshes with the surface of worm 15. The surface of gear 18 meshes with the surface of gear ring 19. There are two sets of gears 20, which are symmetrically distributed inside the fixed frame 14. The surface of gear 20 meshes with the surface of gear ring 19. There are two sets of springs 29, which are symmetrically distributed on the surfaces of the fixed frame 14 and the moving frame 23. One end of spring 29 is connected and fixed to the inner surface of the fixed frame 14, and the other end of spring 29 is fixed to the inner surface of the fixed frame 14. The fixed post 22 is sleeved inside the movable frame 23 and connected to the surface of the movable frame 23. Multiple sets of rollers 38 are arranged in an array inside the backing plate 37. The surface of the rollers 38 is in contact with the side surface of the steel strip roll 4. Four sets of springs 36 and slide rods 35 are symmetrically distributed at the rear end of the backing plate 37 and inside the protective frame 34. The protective frame 34 is N-shaped, with its bottom surface in contact with the surface of the steel strip roll 4. One end of each spring 36 is fixed to the surface of the protective frame 34, and the other end of each spring 36 is fixed to the backing plate. The rear end surface of 37 is connected and fixed. One end of spring 33 is connected and fixed to the bottom end surface of fixed plate 31, and the other end of spring 33 is connected and fixed to the surface of sliding rod 32. The initial state of spring 33 is in a contracted state. Spring 33 connects fixed plate 31 and sliding rod 32 to provide stable support for protective frame 34. Its initial contracted state gives protective frame 34 a certain pre-tightening force, which can quickly respond to changes in the position of steel strip roll 4, adjust the protective and auxiliary positioning posture in time, ensure the stability of the position of steel strip roll 4 throughout the operation, and improve the reliability and adaptability of the centering device.
[0021] Example 2 Please see Figure 3 , Figure 6A fixed plate 31 is fixedly installed on the surface of the fixed frame 14. A sliding rod 32 is fitted inside the fixed plate 31. A spring 33 is fitted on the outer surface of the sliding rod 32. A protective frame 34 is fixedly installed at the top of the sliding rod 32. Sliding rods 35 are fitted inside both sides of the protective frame 34. A spring 46 is fitted on the outer surface of the sliding rod 35. A stop plate 37 is fixedly installed at one end of the sliding rod 35. A roller 38 is fitted inside the stop plate 37. When the steel belt alignment device is activated, two sets of gears 20 symmetrically distributed in the fixed frame 14 begin to rotate under the drive of the gear ring 19. The rotation of the gears 20 drives the rotating plate 21 to rotate, and the fixed column 22 moves accordingly, pushing the movable frame 23 fitted outside it. When the movable frame 23 moves within the fixed frame 14, the two sets of symmetrically distributed springs 29 connecting the fixed frame 14 and the movable frame 23 deform, providing buffering and restoring elastic force for the movable frame 23, ensuring smooth movement of the movable frame 23. This, in turn, drives the movable column 24, the sleeve frame 25, and the pressure cylinder 26 to precisely adjust their positions, performing a stable pressing operation on the steel strip. At the same time, the fixed plate 31 installed on the surface of the fixed frame 3 plays its role. The spring 33, initially contracted, is sleeved on the outside of the sliding rod 32, providing upward support for the protective frame 34 at the top of the sliding rod 32. When the steel strip roll 4 is installed or running, the protective frame 34 can move up and down elastically along the sliding rod 32, adaptively adjusting its height. On both sides of the protective frame 34, the sliding rod 35, the spring 36, the abutment plate 37, and the rollers 38 work together. The spring 36 keeps the abutment plate 37 in elastic contact with the side end of the steel strip roll 4, and the multiple sets of rollers 38 are tightly fitted to the side end of the steel strip roll 4, reducing friction when the steel strip roll 4 rotates. When the diameter of the steel strip coil 4 changes or a slight offset occurs, springs 4 36 and 3 33, through sliding rod 35 and sliding rod 32 respectively, drive the stop plate 37 and the protective frame 34 to flexibly adjust their positions, always maintaining stable protection and auxiliary positioning of the steel strip coil 4, and providing good starting conditions for the steel strip to be aligned.
[0022] Working Principle: When the steel strip alignment device is activated, the two sets of gears 20, symmetrically distributed within the fixed frame 14, begin to rotate under the drive of the gear ring 19. The rotation of the gears 20 drives the rotating plate 21 to rotate, causing the fixed column 22 to move and push the movable frame 23, which is sleeved on its outside. As the movable frame 23 moves within the fixed frame 14, the two sets of symmetrically distributed springs 29 connecting the fixed frame 14 and the movable frame 23 deform, providing buffering and restoring elasticity to the movable frame 23, ensuring smooth movement. This, in turn, drives the movable column 24, the sleeve frame 25, and the pressure cylinder 26 to precisely adjust their positions, performing a stable pressing operation on the steel strip. Simultaneously, the fixed plate 31 mounted on the surface of the fixed frame 3 functions. The initially contracted spring 33 sleeves the sliding rod 32, providing upward support to the protective frame 34 at the top of the sliding rod 32. When the steel strip roll 4 is installed or running, the protective frame 34 can move elastically up and down along the sliding rod 32, adaptively adjusting its height. On both sides of the protective frame 34, the sliding rod 35, spring 36, abutment plate 37 and roller 38 work together. Spring 36 keeps the abutment plate 37 in elastic contact with the side end of the steel strip roll 4, and multiple sets of rollers 38 are in close contact with the side end of the steel strip roll 4 to reduce friction when the steel strip roll 4 rotates. When the diameter of the steel strip coil 4 changes or a slight offset occurs, springs 4 (36) and 3 (33) respectively drive the abutment plate 37 and the protective frame 34 to flexibly adjust their positions through sliding rods 35 and 32, maintaining stable protection and auxiliary positioning of the steel strip coil 4, providing good starting conditions for steel strip alignment. When alignment is required, first insert one end of the steel strip coil 4 through the fixed frame 14, then rotate the rotating block 16. The rotating block 16 drives the worm gear 2 (15) to rotate, and the worm gear 2 (15) meshes with the worm wheel 2 (17), causing the gear 2 (18) at the rear end of the worm wheel 2 (17) to rotate. The gear 2 (18) meshes with the gear ring 19, and the gear ring 19 then drives the gear 3 (20) to rotate. The rotating plate on the surface of the gear 3 (20) rotates. As the rotating plate 21 rotates, the fixed column 22 on the rotating plate 21 drives the moving frame 23 to move downwards. The moving frame 23, through the moving column 24, drives the sleeve frame 25 and the pressure cylinder 26 to move downwards, longitudinally pressing and adjusting the position of the steel strip, and simultaneously performing centering. In addition, during the adjustment process, the spring 27 provides buffering to ensure the smoothness of the adjustment. At the same time, through the two sets of springs 29 and the clamping plate 30, it can adapt to steel strips of different sizes for centering. If it is necessary to adjust the tension of the steel strip, turn the handwheel 10. The handwheel 10 drives the worm gear 9 to rotate. The worm gear 9 meshes with the worm wheel 12, causing the rotating rod 11 to rotate. The gear 13 at the other end of the rotating rod 11 rotates accordingly. Since the gear 13 meshes with the two sets of racks 7, when the gear 13 rotates, it drives the moving rods 6 on both sides to slide in the groove 5 through the racks 7. When the moving rod 6 moves, it drives the fixed frame 14 at the top to move, thereby changing the relative position relationship between the two sets of fixed frames 14, thus realizing tension adjustment.
