Description

Technical Field

[0001] This utility model relates to the field of stainless steel strip production technology, specifically to a looper device for a stainless steel annealing and pickling line. Background Technology

[0002] After cold rolling, stainless steel strip needs to undergo annealing and pickling to improve its quality. Annealing and pickling lines are generally continuous automated production lines. To ensure continuous production, stainless steel annealing and pickling lines are equipped with loopers that can automatically adjust the length of the steel strip to prevent the stainless steel strip from being stretched or curled when the speeds are inconsistent. To ensure the safety margin of the annealing and pickling line, the loopers in the stainless steel annealing and pickling line have a large number of layers and a long length. There are many support rollers in the loopers, and the stainless steel strip wound in the loopers is also relatively long. To prevent the stainless steel strip wound in the loopers from shifting, many loopers are equipped with active correction devices. The active correction device uses a shift detection sensor and a correction motor to control the swaying movement of the support rollers, which can correct stainless steel strips with large shifts. However, due to the large number of support rollers in the loopers, the active correction device is not very effective in correcting the stainless steel strip in the entire looper.

[0003] Chinese patented invention CN206298651U discloses a non-powered correction roller structure for a stainless steel strip annealing and pickling line. The structure includes a support roller within the loop, with each set of support rollers containing paired sub-support rollers arranged at an angle. Each sub-support roller has a roller shaft, two support seats for the support roller shaft, and a mounting plate for mounting the support seats. An adjustment component is provided between the support seats and the mounting plate to adjust the angle between the two roller shafts. Each adjustment component includes a guide seat, an adjusting slider, and a locking block. The guide seat has a guide groove, and the two sides of the adjusting slider slide in cooperation with the guide groove. The adjusting slider is connected to an adjusting screw, and the locking block has a locking positioning screw. This invention utilizes adjustable-angle sub-support rollers for correction, resulting in a simple, stable, and reliable structure. No operator intervention is required during operation, and the support rollers do not need to be connected to an active correction device. It also features low manufacturing costs and convenient use and maintenance.

[0004] However, the device still has some problems. In actual use, when adjusting the angle of the sub-support rollers to adapt to different specifications of stainless steel strips or to correct deviation, the staff needs to manually adjust the adjustment components of each support roller one by one. Since there are usually multiple support rollers in the looper device, this manual adjustment method makes the adjustment process cumbersome, time-consuming and inefficient. Therefore, we propose a looper device for stainless steel annealing and pickling lines to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a looper device for a stainless steel annealing and pickling line, which solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A loose-fitting device for a stainless steel annealing and pickling line includes a main body. Multiple side plates are welded to the top of the main body. Multiple support seats are fixedly connected between two opposite side plates. Four support blocks are fixedly connected to the top of each support seat. A rotating shaft is rotatably connected between two opposite support blocks. A first connecting block is fixedly connected to the rotating shaft. A second connecting block is provided on one side of the first connecting block. A support roller is rotatably connected between the first connecting block and the corresponding second connecting block. Two rectangular blocks are welded to the top of the support seats. A lead screw is rotatably connected to one side of each rectangular block. A moving rod is threaded onto the lead screw. A square block is welded to the end of the moving rod. An inclined hinge arm is hinged to one side of the square block. The end of the hinge arm is hinged to the bottom of the corresponding second connecting block. A motor is fixedly connected to the other side of the rectangular block.

[0010] Furthermore, the end of the lead screw extends to the other side of the rectangular block and is fixedly connected to the output shaft of the motor.

[0011] Furthermore, two square rods are welded to one side of the rectangular block, and an L-shaped rod is slidably connected to the square rod.

[0012] Furthermore, the end of the L-shaped rod is fixedly connected to one side of the corresponding movable rod.

[0013] Furthermore, the movable rod has a threaded hole, and the movable rod is threadedly connected to the corresponding lead screw through the threaded hole.

[0014] Furthermore, a limiting groove is provided on the L-shaped rod, and the L-shaped rod is slidably connected to the corresponding square rod through the limiting groove.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a looper device for a stainless steel annealing and pickling line, which has the following advantages:

[0017] This invention, by starting the corresponding motor to rotate in the forward direction, causes the motor output shaft to rotate. Since the motor output shaft is fixedly connected to the end of the lead screw, the lead screw rotates synchronously. The lead screw drives the corresponding moving rod to move, and the moving rod drives the hinge arm to move through the block. Because the hinge arm is tilted, its swing transmits force to the second connecting block, causing the second connecting block to rotate around the rotation connection point with the first connecting block. The support roller is rotatably connected between the first and second connecting blocks. The rotation of the second connecting block causes the angle of the support roller to change, thereby automatically adjusting the angle of the support roller and adjusting the included angle between the two relative support rollers, thus improving work efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Example

[0025] like Figure 1-4As shown in the figure, an embodiment of the present invention provides a loose-fitting device for a stainless steel annealing and pickling line, comprising a device body 1, a plurality of side plates 2 welded to the top of the device body 1, a plurality of support seats 3 fixedly connected between two opposite side plates 2, four support blocks 4 fixedly connected to the top of the support seats 3, a rotating shaft 5 rotatably connected between two opposite support blocks 4, a first connecting block 6 fixedly connected to the rotating shaft 5, a second connecting block 7 provided on one side of the first connecting block 6, a support roller 8 rotatably connected between the first connecting block 6 and the corresponding second connecting block 7, two rectangular blocks 9 welded to the top of the support seats 3, a lead screw 10 rotatably connected to one side of the rectangular blocks 9, a moving rod 11 threadedly connected to the lead screw 10, a square block 12 welded to the end of the moving rod 11, an inclined hinge arm 13 hinged to one side of the square block 12, the end of the hinge arm 13 hinged to the bottom of the corresponding second connecting block 7, and a motor 14 fixedly connected to the other side of the rectangular blocks 9.

[0026] In use, when the angle of the support roller 8 needs to be adjusted according to the specifications, operating status, or deviation of the stainless steel strip, the corresponding motor 14 is started to rotate in the forward direction. The output shaft of the motor 14 begins to rotate. Since the output shaft of the motor 14 is fixedly connected to the end of the lead screw 10, the lead screw 10 rotates synchronously. The lead screw 10 drives the corresponding moving rod 11 to move. The moving rod 11 drives the hinge arm 13 to move through the corresponding block 12. The hinge arm 13 pulls the corresponding second connecting block 7. Since the hinge arm 13 is tilted, its swing will transmit force to the second connecting block 7, causing the second connecting block 7 to rotate around the rotation connection point with the first connecting block 6. The support roller 8 is rotatably connected between the first connecting block 6 and the second connecting block 7. The rotation of the second connecting block 7 will cause the angle of the support roller 8 to change, thereby automatically adjusting the angle of the support roller 8 and adjusting the included angle of the two relative support rollers 8, improving work efficiency.

[0027] In some embodiments, the end of the lead screw 10 extends to the other side of the rectangular block 9 and is fixedly connected to the output shaft of the motor 14.

[0028] In some embodiments, two square rods 15 are welded to one side of the rectangular block 9, and an L-shaped rod 16 is slidably connected to the square rod 15. The end of the L-shaped rod 16 is fixedly connected to one side of the corresponding movable rod 11. A limiting groove is provided on the L-shaped rod 16, and the L-shaped rod 16 is slidably connected to the corresponding square rod 15 through the limiting groove.

[0029] The square rod 15 serves to limit and guide the L-shaped rod 16, thereby restricting the moving rod 11 to only move in a straight line along the axis of the lead screw 10, and preventing the moving rod 11 from rotating with the lead screw 10 when the lead screw 10 rotates.

[0030] In some embodiments, the moving rod 11 has a threaded hole, and the moving rod 11 is threadedly connected to the corresponding lead screw 10 through the threaded hole.

[0031] Under the interlocking force of the threaded hole and the lead screw 10, the moving rod 11 can be locked and fixed after moving to the appropriate position, and there will be no displacement.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
