Description

Technical Field

[0001] This utility model relates to the technical field of strip steel processing equipment, and in particular to a feed inlet limiting device for strip steel leveling equipment. Background Technology

[0002] A strip leveling machine is an industrial device used to correct surface unevenness defects in metal strips (such as cold-rolled and hot-rolled steel plates). It primarily uses multiple sets of staggered rollers to apply continuous bending and tensile forces to the strip, eliminating internal residual stress and restoring it to a flat state. During strip processing, to ensure the leveling effect, the strip must be accurately centered and maintain a stable feeding posture as it enters the leveling equipment's inlet. Therefore, an inlet limiting device is required.

[0003] A search revealed Chinese Patent Publication No. CN211839628U, which discloses a strip steel leveling machine, including a machine casing and a leveling mechanism disposed within the machine casing. The leveling mechanism includes a feeding mechanism, a fixed pressure roller mechanism, a lifting pressure roller mechanism, and a dust removal mechanism, all sequentially disposed within the machine casing. The feeding mechanism includes two feeding rollers arranged vertically, with one of the feeding rollers having a drive mechanism for rotating via a rotating shaft. The fixed pressure roller mechanism includes several upper and lower pressure rollers arranged vertically, with the upper and lower pressure rollers staggered, and the number of lower pressure rollers exceeding the number of upper pressure rollers. The lifting pressure roller mechanism includes a driving wheel and a driven wheel arranged vertically, with the driving wheel having a drive mechanism for rotating via a rotating shaft, and the driving wheel having a lifting mechanism for adjusting the distance between the driving wheel and the driven wheel via a bushing.

[0004] In the above-mentioned utility model, two feeding wheels are set in the feeding mechanism inside the machine box. The feeding is achieved by the two feeding wheels adhering to the strip steel. However, in actual use, the limiting rollers are usually fixed with bolts at the feed inlet of the previous leveling equipment, which is not convenient for adjustment. As a result, when the strip steel enters the leveling equipment, the direction of the strip steel may not be directly facing the feed inlet, which will affect the leveling effect of the strip steel. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a limiting device for the inlet of a strip steel leveling equipment, which aims to improve the problem that the limiting roller is usually fixed with bolts at the inlet of the leveling equipment, making it inconvenient to adjust the position of the limiting roller, thus affecting the entry of the strip steel into the inlet of the leveling equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feed inlet limiting device for a strip leveling equipment includes a base plate. A leveling machine is fixedly connected to the upper surface of the base plate. A feed platform is fixedly connected to the upper surface of the base plate. A motor is fixedly connected to the upper surface of the feed platform. A sprocket is fixedly mounted on the output end of the motor. A chain is mounted on the outer wall of the sprocket. A sprocket is mounted on the inner wall of the chain. A bidirectional stud is fixedly connected inside the sprocket. The outer wall of the bidirectional stud is rotatably connected to the inside of the feed platform. A base is threadedly connected to the outer wall of the bidirectional stud. A limiting roller is mounted on the outer wall of the base. A guide post is slidably connected inside the base. Both ends of the guide post are fixedly connected to the inner wall of the feed platform. A limiting component is mounted on the outer wall of the base.

[0008] The above technical solution involves: the strip steel is guided through the limiting rollers around the feeding platform to limit its movement, and finally the strip steel is guided into the leveling machine for leveling. A square plate is installed on the outer wall of the feeding platform to fix the motor. The motor drives sprocket one, which, through the transmission of chain and sprocket two, causes the bidirectional stud to rotate inside the feeding platform, thereby adjusting the position of the limiting rollers on both sides of the feeding platform. This facilitates the limiting of strip steel of different widths. The U-shaped base facilitates the installation of the limiting rollers on the left and right sides of the same transverse direction.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a limiting sleeve, the inside of which is slidably connected to the outer wall of the base, and a pin is slidably connected inside the limiting sleeve, the outer wall of which is slidably connected to the inside of the base.

[0011] The above technical solution involves placing a limiting sleeve over the base and using a pin that passes through the base and the inside of the limiting sleeve to limit the installation of the pin.

[0012] As a further description of the above technical solution:

[0013] The feeding platform is equipped with a lower roller, a fixed frame, and an upper roller.

[0014] The above technical solution utilizes the lower and upper rollers of the feeding platform to fit closely with the strip steel, thereby improving the stability of the strip steel conveying process.

[0015] As a further description of the above technical solution:

[0016] A fixing block is fixedly connected to the outer wall of the fixing frame, and a hollow block is slidably connected inside the fixing block. The outer wall of the hollow block is fixedly connected to the outer wall of the feeding platform.

[0017] The above technical solution involves fixing the fixed block with a fixing frame and fixing the hollow block with a feeding platform. The connection between the fixed block and the hollow block improves the stability of the fixing frame installation.

[0018] As a further description of the above technical solution:

[0019] The hollow block is internally connected to a cross block, and the cross block is internally connected to a sliding rod.

[0020] The above technical solution limits the movement of the cross block by having its outer wall slide inside the hollow block and the inside of the cross block slide on the outer wall of the slide rod.

[0021] As a further description of the above technical solution:

[0022] Both ends of the slide rod are fixedly connected to the inner wall of the hollow block, and a spring is provided on the outer wall of the slide rod.

[0023] The above technical solution utilizes a hollow block to fix the sliding rod, while the sliding rod is positioned inside the hollow part of the spring to limit the shortening or elongation of the spring.

[0024] As a further description of the above technical solution:

[0025] One end of the spring is fixedly connected to the lower surface of the cross block, and the other end of the spring is fixedly connected to the inner bottom wall of the hollow block.

[0026] The above technical solution involves connecting one end of a spring to a fixed hollow block and the other end to a movable cross block, thereby limiting the range of movement of the cross block.

[0027] As a further description of the above technical solution:

[0028] The interior of the cross block is rotatably connected to a U-shaped frame, and the outer wall of the U-shaped frame is rotatably connected to a sliding frame. The outer wall of the sliding frame penetrates the interior of the hollow block and is slidably connected to the interior of the fixed block.

[0029] The above technical solution involves pressing the cross block, which drives the sliding frame through the U-shaped frame. The movement of the sliding frame is limited by the interior of the hollow block. The sliding frame then slides into the interior of the fixed block, which in turn limits the movement of the fixed block.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the distance between the front and rear limit rollers is adjusted by the cooperation between the motor, sprocket one, chain, sprocket two, double-acting stud, base, guide column and limit assembly, so that the strip steel enters directly facing the feed port of the leveling machine, making the effect of the leveling roller on the strip steel more uniform, improving the leveling accuracy, and also adapting to the feeding of strip steel of different widths, thus improving the applicability of the device.

[0032] 2. In this utility model, the fixed frame and the upper roller are quickly installed and disassembled through the cooperation between the hollow block, the cross block, the slide rod, the spring, the U-shaped frame, the sliding frame and the fixed block. According to the actual production needs, the appropriate upper roller can be quickly replaced, which improves the versatility and flexibility of the device. At the same time, it is convenient to inspect and repair the severely worn upper roller. Attached Figure Description

[0039] 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.

[0040] Reference Figure 1 and Figure 2 An embodiment of this utility model provides: a feed inlet limiting device for a strip leveling equipment, including a base plate 1, a leveling machine 2 fixedly connected to the upper surface of the base plate 1, a feed platform 3 fixedly connected to the upper surface of the base plate 1, a motor 4 fixedly connected to the upper surface of the feed platform 3, a sprocket 5 fixedly provided at the output end of the motor 4, a chain 6 provided on the outer wall of the sprocket 5, a sprocket 7 provided on the inner wall of the chain 6, a bidirectional stud 8 fixedly connected inside the sprocket 7, the outer wall of the bidirectional stud 8 rotatably connected to the inside of the feed platform 3, a base 9 threadedly connected to the outer wall of the bidirectional stud 8, a limiting roller 10 provided on the outer wall of the base 9, a guide post 11 slidably connected inside the base 9, both ends of the guide post 11 fixedly connected to the inner wall of the feed platform 3, and a limiting component 12 provided on the outer wall of the base 9;

[0041] Specifically, the strip steel is leveled by the leveling rollers inside the leveling machine 2. The motor 4 drives the sprocket 5, which in turn drives the sprocket 7. The sprocket 7 drives the bidirectional stud 8 to rotate. The rotation of the bidirectional stud 8 inside the feed platform 3 provides support. The bidirectional stud 8 drives the bases 9 and the limiting rollers 10 on both sides to move synchronously. The bidirectional stud 8 and the center of the feed platform 3 are in the same position, and the feed platform 3 and the leveling machine 2 are horizontally parallel. The limiting rollers 10 guide the strip steel to the feed port of the leveling machine 2 at the center of the feed platform 3. The fixed guide column 11 provides support and limits the movement of the base 9.

[0042] Reference Figure 2 The limiting component 12 includes a limiting sleeve 1201, the inside of which is slidably connected to the outer wall of the base 9, and a pin 1202 is slidably connected inside the limiting sleeve 1201, the outer wall of which is slidably connected to the inside of the base 9.

[0043] Specifically, short rods are provided on both sides of the base 9, and a limiting sleeve 1201 is set on the upper outer wall of the short rod. The pin 1202 passes through the limiting sleeve 1201 and the short rod to limit the range of objects within the range of the short rod.

[0044] Reference Figure 1 and Figure 3 The feed platform 3 is equipped with a lower roller 15, a fixed frame 13, and an upper roller 14.

[0045] Specifically, the rotation of the lower roller 15 inside the feed platform 3 achieves the supporting effect. The lower surface of the fixed frame 13 is provided with a slider that slides inside the feed platform 3, thereby positioning the fixed frame 13 and preventing wobbling. The fixed frame 13 supports the rotation of the upper roller 14.

[0046] Reference Figure 3 and Figure 4 A fixed block 16 is fixedly connected to the outer wall of the fixed frame 13. A hollow block 17 is slidably connected inside the fixed block 16. The outer wall of the hollow block 17 is fixedly connected to the outer wall of the feed platform 3. A cross block 18 is slidably connected inside the hollow block 17. A sliding rod 19 is slidably connected inside the cross block 18. Both ends of the sliding rod 19 are fixedly connected to the inner wall of the hollow block 17. A spring 20 is provided on the outer wall of the sliding rod 19. One end of the spring 20 is fixedly connected to the lower surface of the cross block 18, and the other end of the spring 20 is fixedly connected to the inner bottom wall of the hollow block 17. A U-shaped frame 21 is rotatably connected inside the cross block 18. A sliding frame 22 is rotatably connected to the outer wall of the U-shaped frame 21. The outer wall of the sliding frame 22 penetrates the interior of the hollow block 17 and is slidably connected to the interior of the fixed block 16.

[0047] Specifically, after the fixed block 16 and the hollow block 17 are fitted together, without the action of external force driving the cross block 18, the spring 20 itself holds the cross block 18 in place, thereby providing support for the sliding frame 22 to slide into the interior of the fixed block 16 through the U-shaped frame 21, thus installing the fixed block 16. The movement of the cross block 18 is offset and limited by the interior of the hollow block 17. The slide rod 19 prevents the cross block 18 from shaking when it moves. Short rods are provided on both sides of the U-shaped frame 21 to connect with the cross block 18 and the sliding frame 22, facilitating the transmission of the sliding frame 22 by the cross block 18. A slider is provided on the rear outer wall of the sliding frame 22 and is located at one end near the slide rod 19. The slider slides inside the hollow block 17, achieving the effect of supporting and limiting the movement of the sliding frame 22.

[0048] Working principle: When using this device, the strip steel passes through the upper roller 14 and the lower roller 15, and is guided to the rollers set inside the leveling machine 2. Then, the motor 4 drives the sprocket 5, which in turn drives the chain 6 to rotate the sprocket 7 and the double-sided stud 8. The double-sided stud 8 drives the bases 9 on both sides to move towards the center of the double-sided stud 8 through the outer wall of the guide column 11. This drives the limiting rollers 10 on both sides to move towards the center of the double-sided stud 8, limiting the strip steel between the upper roller 14 and the lower roller 15. This ensures that the strip steel entering the leveling machine 2 travels in a direction that is directly opposite the feed port of the leveling machine 2. The installation of the limiting sleeve 1201 by the pin 1202 limits the rotation range of the limiting roller 10.

[0049] When the upper roller 14 needs adjustment, press the cross block 18 and slide it downward on the outer wall of the slide bar 19 to compress the spring 20. The cross block 18 drives the U-shaped frame 21 to rotate downward and move to the right, thereby driving the sliding frame 22 to slide to the right inside the hollow block 17. The sliding frame 22 slides to the right and out of the fixed block 16, no longer limiting the fixed block 16, thus quickly disassembling the fixed frame 13 and the upper roller 14. Move the replaced upper roller 14 and fixed frame 13 along the inside of the feed table 3 so that the fixed block 16 and the hollow block 17 fit together. Then release the cross block 18. Under the elastic force of the spring 20, drive the sliding frame 22 to move to the left and limit the fixed block 16, thus installing the replaced upper roller 14 and fixed frame 13. During use, this device not only limits the conveyed strip steel, but also enables the quick installation and disassembly of the upper roller 14 and fixed frame 13.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
