Description

Technical Field

[0001] This application relates to the technical field of steel production, and in particular to a strip steel looper. Background Technology

[0002] As an indispensable core piece of equipment in the automated production of high-frequency straight seam welded pipes, the looper's functional value permeates the entire production process. By precisely controlling material storage, it establishes a dynamic balance between raw material supply and the main rolling mill's processing rhythm. When there are brief fluctuations in the material supply, the looper can release reserve raw materials in real time to maintain the continuous operation of the main rolling mill; conversely, when the material supply is sufficient, it can efficiently store excess material to prevent material buildup and blockage. This dual function of material storage buffering and supply regulation not only eliminates downtime losses caused by intermittent material supply but also achieves continuous and stable operation of the rolling mill through automated logic control, becoming a key hub for ensuring the efficiency and quality of welded pipe production.

[0003] In existing technologies, the tension control of some strip loopers is not precise enough. When the speed of the unit in the production line changes slightly, the tension of the strip inside the looper is prone to large fluctuations, which can lead to quality problems such as strip deviation and wrinkles, seriously affecting the quality of the finished strip. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a strip looper that overcomes the deficiencies of the prior art. It aims to solve the problem that the tension control of some strip loopers is not precise enough. When the speed of the unit in the production line changes slightly, the tension of the strip inside the looper is prone to large fluctuations, which leads to quality problems such as strip deviation and wrinkles, seriously affecting the quality of the finished strip.

[0005] To achieve the above objectives, this application provides the following technical solution: a strip sleeve, comprising a base plate, two upright plates connected to the top surface of the base plate, an mounting plate slidably disposed between the two upright plates, an mounting box connected to the top surface of the mounting plate, a sliding groove through-cutting on one side of the mounting box, a rack slidably disposed inside the sliding groove, a limit plate connected to one end of the rack, a first motor disposed inside the mounting box, a gear connected to the output end of the first motor, and the gear meshing with the rack.

[0006] By adopting the above technical solution, after the first motor starts, the output shaft drives the gear to rotate. The gear meshes with the rack, converting the circular motion of the gear into the linear sliding of the rack in the groove. The rack drives the limit plate to move laterally, thereby adjusting the position of the limit plate in the running path of the strip. By driving the gear and rack mechanism with the motor, the position adjustment of the limit plate can be realized, and the lateral movement range of the strip can be controlled in real time to prevent deviation.

[0007] As a preferred technical solution of this application, the top surface of the base plate is connected to a lower crossbeam, and the lower crossbeam is rotatably equipped with a plurality of lower rollers, which are spaced apart.

[0008] By adopting the above technical solution, the strip steel is laid above the lower roller, which can rotate around its axis. When the strip steel moves, the lower roller rolls with it, converting sliding friction into rolling friction. Multiple lower rollers are distributed at intervals to evenly bear the weight of the strip steel and avoid localized stress deformation.

[0009] As a preferred technical solution of this application, the bottom surface of the mounting plate is connected to an upper crossbeam, and the upper crossbeam is rotatably equipped with a plurality of upper rollers, which are spaced apart.

[0010] By adopting the above technical solution, the upper and lower rollers cooperate to form an upper and lower clamping structure for the strip steel. When the mounting plate moves up and down, the upper roller rises and falls accordingly, changing the distance between the upper and lower rollers, thereby adjusting the strip steel tension. By adjusting the position of the upper roller, the strip steel tension can be flexibly adjusted, avoiding breakage caused by insufficient tension leading to slack or excessive tension.

[0011] As a preferred technical solution of this application, a second motor is connected to the top surface of the base plate, and a lead screw is connected to the output end of the second motor. The outer wall of the lead screw is threadedly connected to the mounting plate.

[0012] By adopting the above technical solution, the second motor is started, and its output end drives the lead screw to rotate. The mounting plate drives the upper cross frame and upper roller to rise and fall synchronously, and the distance between the upper and lower rollers is adjusted. The electric lead screw transmission can control the lifting distance of the mounting plate to adapt to different thicknesses of strip steel or different tension requirements.

[0013] As a preferred technical solution of this application, a guide rod is provided on the top surface of the base plate, and the mounting plate is slidably disposed with respect to the outer wall of the guide rod.

[0014] By adopting the above technical solution, the guide rod restricts the movement trajectory of the mounting plate, allowing it to slide up and down along the axial direction of the rod, thus avoiding lateral deviation. The guide rod cooperates with the lead screw to ensure the balance of the mounting plate during lifting and lowering, preventing the mounting plate from tilting or shaking during the lifting and lowering process, and ensuring the accuracy of the upper roller position adjustment.

[0015] As a preferred technical solution of this application, the limiting plate is disposed between the lower roller and the upper roller, and the shape of the limiting plate is a rectangular block.

[0016] By adopting the above technical solution, when the rectangular limit plates move towards each other, their sides block the edge of the strip steel, restricting the lateral displacement of the strip steel. The gear and rack mechanism adjusts the lateral position of the limit plates to adapt to strip steel of different widths. The rectangular structure provides a stable blocking surface, effectively preventing the strip steel from deviating from the track during operation. By adjusting the position of the limit plates, it can adapt to strip steel of different specifications, thus improving the applicability of the equipment.

[0017] As a preferred technical solution of this application, a fixing plate is connected to the top surface of the upright plate.

[0018] By adopting the above technical solution, the fixing plate is fixed to the top of the upright plate, providing an additional support point for the top of the equipment. The fixing plate enhances the rigidity of the top of the upright plate, reduces vibration during equipment operation, and improves the overall structural stability.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: 1. The first motor inside the mounting box drives the gear to rotate, and the rack meshing with the gear can slide in the slide groove, thereby driving the limit plate to move in opposite directions. This design can avoid problems such as strip deviation and stacking during the operation of the strip, ensuring that the strip maintains a stable tension during processing, and improving the processing quality and production efficiency of the strip.

[0020] 2. When the second motor is working, the screw rotates and drives the mounting plate to slide up and down along the guide rod, thereby causing the upper crossbeam and upper roller on the mounting plate to rise and fall synchronously. The vertical distance between the upper roller and the lower roller can be adjusted to accommodate strip steel of different thicknesses and control the position of the strip steel in the vertical direction. This function helps the strip steel to be smoothly transported in the looper and reduces processing errors caused by position deviation. Attached Figure Description

[0023] 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.

[0024] like Figure 1 - Figure 5 As shown, this embodiment provides a strip steel looper, including a base plate 1, two upright plates 2 connected to the top surface of the base plate 1, an mounting plate 3 slidably disposed between the two upright plates 2, an mounting box 4 connected to the top surface of the mounting plate 3, a sliding groove 5 extending through one side of the mounting box 4, a rack 6 slidably disposed inside the sliding groove 5, a limit plate 7 connected to one end of the rack 6, a first motor 8 disposed inside the mounting box 4, a gear 9 connected to the output end of the first motor 8, the gear 9 meshing with the rack 6, by starting the first motor 8, its output shaft drives the gear 9 to rotate, the gear 9 meshing with the rack 6, converting the circular motion of the gear 9 into the linear sliding of the rack 6 in the sliding groove 5, the rack 6 driving the limit plate 7 to move laterally, thereby adjusting the position of the limit plate 7 in the strip steel running path, by driving the gear 9 and rack 6 mechanism with the motor to realize the position adjustment of the limit plate 7, can control the lateral movement range of the strip steel in real time, and prevent deviation.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, the top surface of the base plate 1 is connected to a lower crossbeam 10. Several lower rollers 11 are rotatably arranged inside the lower crossbeam 10. The lower rollers 11 are spaced apart. The strip steel is laid on top of the lower rollers 11. The lower rollers 11 can rotate around the axis. When the strip steel moves, the lower rollers 11 roll with it, converting sliding friction into rolling friction. The multiple lower rollers 11 are spaced apart to evenly bear the weight of the strip steel and avoid local deformation due to stress.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, the bottom surface of the mounting plate 3 is connected to an upper crossbeam 12. Several upper rollers 13 are rotatably arranged inside the upper crossbeam 12. The upper rollers 13 are spaced apart and cooperate with the lower rollers 11 to form an upper and lower clamping structure for the strip steel. When the mounting plate 3 moves up and down, the upper rollers 13 rise and fall accordingly, changing the distance between the upper rollers 13 and the lower rollers 11, thereby adjusting the strip steel tension. By adjusting the position of the upper rollers 13, the strip steel tension can be flexibly adjusted to avoid breakage caused by insufficient tension leading to slack or excessive tension.

[0027] In this embodiment, as Figure 1 and Figure 4As shown, a second motor 14 is connected to the top surface of the base plate 1. The output end of the second motor 14 is connected to a lead screw 15. The outer wall of the lead screw 15 is threadedly connected to the mounting plate 3. When the second motor 14 is started, its output end drives the lead screw 15 to rotate. The mounting plate 3 drives the upper crossbeam 12 and the upper roller 13 to rise and fall synchronously. The distance between the upper roller 13 and the lower roller 11 can be adjusted. The electric lead screw 15 can control the lifting distance of the mounting plate 3 to adapt to different thicknesses of strip steel or different tension requirements.

[0028] In this embodiment, as Figure 5 As shown, a guide rod 16 is provided on the top surface of the base plate 1. The mounting plate 3 is slidably disposed on the outer wall of the guide rod 16. The guide rod 16 restricts the movement trajectory of the mounting plate 3, so that it can only slide up and down along the axial direction of the rod to avoid lateral deviation. The guide rod 16 cooperates with the lead screw 15 to ensure the balance of the mounting plate 3 when it is raised and lowered, prevent the mounting plate 3 from tilting or shaking during the raising and lowering process, and ensure the accuracy of the position adjustment of the upper roller 13.

[0029] In this embodiment, as Figure 1 and Figure 3 As shown, the limiting plate 7 is set between the lower roller 11 and the upper roller 13. The limiting plate 7 is rectangular. When the rectangular limiting plate 7 moves towards each other, its side will block the edge of the strip steel, restricting the lateral displacement of the strip steel. The gear 9 and rack 6 mechanism adjusts the lateral position of the limiting plate 7 to adapt to strip steel of different widths. The rectangular structure provides a stable blocking surface, effectively preventing the strip steel from deviating from the track during operation. By adjusting the position of the limiting plate 7, it can be adapted to strip steel of different specifications, thus improving the applicability of the equipment.

[0030] In this embodiment, as Figure 4 and Figure 5 As shown, a fixing plate 17 is connected to the top surface of the upright plate 2. The fixing plate 17 is fixed to the top of the upright plate 2, providing an additional support point for the top of the equipment. The fixing plate 17 enhances the rigidity of the top of the upright plate 2, reduces vibration during equipment operation, and improves the overall structural stability.

[0031] Working principle: After the worker puts the strip steel into the looper from the external equipment, it passes through the lower roller 11 on the lower crossbeam 10 and the upper roller 13 on the upper crossbeam 12 in sequence. By controlling the second motor 14, the vertical distance between the upper roller 13 and the lower roller 11 can be adjusted, thereby changing the tension of the strip steel. The first motor 8 in the mounting box 4 drives the gear 9 to rotate. The rack 6 meshing with the gear 9 slides along the slide groove 5, thereby driving the limiting plate 7 connected to one end of the rack 6 to move towards each other. The limiting plate 7 is located on both sides of the strip steel between the lower roller 11 and the upper roller 13. By adjusting its lateral position, a lateral restraint force can be applied to the strip steel to prevent the strip steel from running off-center or stacking during the conveying process.

[0032] The above are merely preferred embodiments of this application and are not intended to limit this application. Although this application 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.
