Description

Technical Field

[0001] This utility model relates to the field of steel coil packaging technology, specifically to an automatic bundling device for high-strength steel coils. Background Technology

[0002] In the iron and steel metallurgy and metal processing industry, steel coils, as an important finished product of steel, are widely used in many fields such as automobile manufacturing, home appliance production, and building materials. After the steel coils are produced, they need to be bundled before they can be stored and transported long distances. The strong bundling not only protects the surface of the steel coils from scratches, rust and other damage, but also prevents the steel coils from becoming loose or deformed during handling and transportation, ensuring the safety and efficiency of the entire logistics process.

[0003] Common steel coil bundling devices mostly rely solely on conveyor rollers for simple support when bundling steel coils, lacking a temporary fixing structure specifically for the ends of the coils. In actual bundling, when the bundling strap applies tension to one end of the coil to tighten it, the coil is prone to rolling in the radial direction due to unbalanced forces because the other end is not effectively restrained. This rolling can not only cause the coil to collide with nearby operators, posing a personal safety hazard, but also collide with surrounding equipment, leading to equipment damage and seriously affecting the safety and stability of production operations.

[0004] Patent CN218907732U discloses a high-efficiency steel coil bundling device. Two crossbeams connect the support frames, and a movable frame is mounted on the two crossbeams. A first steel strip channel and a second steel strip channel are respectively provided on opposite sides of the movable frame. A first electric push rod is mounted on the top of the movable frame via a fixed block. A top plate is located at the lower end of the first electric push rod. Channel steel is provided on the lower side of the top plate via two connecting plates. A steel strip drum is mounted on the fixed block, and steel strip is wound around the drum. A winding mechanism can tighten the annular steel strip, a fixing mechanism can fix the overlapping steel strips within the channel steel together, and a shearing mechanism cuts the steel strip to bundle the steel coil.

[0005] However, this patent has the following drawbacks: during the binding process, the steel coil is in a loose state. The steel coil is prone to accidental rolling or tipping during binding, which may cause it to hit the operator or damage the surrounding equipment. The steel coil may rotate slightly as the binding strap tightens, resulting in insufficient actual tension of the binding strap, which may lead to loosening during transportation. Utility Model Content

[0006] To address the shortcomings of existing technologies, such as the lack of temporary fixation at the ends of steel coils during bundling, the inability to secure the other end during actual bundling, and the resulting radial roll due to unbalanced forces, which can lead to collisions with nearby operators and equipment damage, thus severely impacting the safety and stability of production operations, this invention provides an automatic bundling device for high-strength steel coils.

[0007] The objective of this utility model can be achieved through the following technical solutions: An automatic bundling device for high-strength steel coils includes a first support frame and a second support frame. A first fixing ring is fixedly connected to the upper surface of the second support frame. A first limiting groove is formed in the middle of the outer side of the first fixing ring. An annular spring is provided in the first limiting groove. A second fixing ring is fixedly connected to the outer wall of the first limiting groove. A first slot is formed inside the second fixing ring. Multiple evenly distributed second and third limiting grooves are formed inside the first fixing ring. A second limiting block is provided in the second limiting groove. A first limiting block is provided in the third limiting groove. A through second slot is formed on the side of the first limiting block near the second fixing ring. The annular spring is installed in the second slot.

[0008] Furthermore, the second limiting groove is located on the side close to the second fixed ring, and the third limiting groove is disposed through the second fixed ring on the side away from the second fixed ring, and the second fixed ring passes through the first fixed ring; the width of the second limiting groove is greater than the width of the third limiting groove.

[0009] Furthermore, a third slot is provided on the side of the second limiting block away from the second fixing ring, and multiple evenly arranged second rotating shafts are rotatably arranged in the third slot, with the second rotating shafts arranged parallel to the first fixing ring.

[0010] Furthermore, the first limiting groove is annular in shape, the width of the first groove opening is greater than the width of the first limiting groove, and the diameter of the first fixing ring is smaller than the diameter of the second fixing ring.

[0011] Furthermore, a first rotating shaft is provided between the first support frames, a conveyor belt is provided in the middle of the first rotating shaft, synchronous toothed belts are provided on both sides of the conveyor belt, synchronous pulleys are provided on both sides of the synchronous toothed belt, and the conveyor belt is provided with a pattern; the pattern is in the shape of a diamond-shaped protrusion.

[0012] Furthermore, one side of the annular spring is fixedly connected to one end of the second limiting block, and the annular spring near one end of the second limiting block is fixedly connected to the side wall of the second slot.

[0013] The beneficial effects of this utility model are: This invention utilizes the cooperation between the second and third limiting blocks and the annular spring to temporarily fix one end of the steel coil during bundling. When the other end of the steel coil is bundled, the tension is balanced by the clamping force of the fixed end, preventing radial rolling of the steel coil during bundling and avoiding impact on operators or damage to surrounding equipment. On the other hand, it can reduce the occurrence of "loose" bundling straps, ensuring accurate bundling position and uniform tension of the strapping, which can meet the stress requirements during subsequent warehousing and transportation.

[0016] 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.

[0017] Please see Figure 1-2As shown, an automatic strapping device for high-strength steel coils includes a first support frame 11 and a second support frame 3. The first support frames 11 are symmetrically arranged, and a first rotating shaft 14 is provided between the symmetrically arranged first support frames 11. A conveyor belt 1 is provided in the middle of the first rotating shaft 14, and synchronous toothed belts 13 are provided on both sides of the conveyor belt 1. Synchronous pulleys are provided on both sides of the synchronous toothed belts 13. A motor 12 is provided at one end of the first rotating shaft 14, and the motor 12 is used to drive the first rotating shaft 14 to rotate. In order to increase the friction on the conveyor belt 1, a pattern 15 is provided on the conveyor belt 1. The pattern 15 is in the shape of a diamond-shaped protrusion. The conveyor belt 1 is symmetrically distributed. A strapping machine (not shown in this embodiment) is provided on one side of the conveyor belt 1. The strapping machine in this embodiment adopts the KZ-32 series of Shanghai Xinnai steel strapping machine.

[0018] In this embodiment, the diamond-shaped raised pattern 15 with a spacing of 50mm and a height of 8mm can significantly increase the static friction between the steel coil and the conveyor belt 1. This not only prevents the steel coil from rolling off due to inertia during start-up, stop, or uniform speed conveying, but also reduces the direct contact area between the surface of the steel coil and the conveyor belt 1, thereby reducing the risk of scratches on the outer surface of the steel coil.

[0019] A second support frame 3 is provided between the conveyor belts 1. A first fixing ring 2 is fixedly connected to the upper surface of the second support frame 3. A first limiting groove 22 is provided in the middle of the outer side of the first fixing ring 2. The first limiting groove 22 is annular in shape. An annular spring 2201 is provided in the first limiting groove 22.

[0020] Please see Figure 3-4 As shown, a second fixing ring 21 is fixedly provided on the outer wall of the first limiting groove 22. A first slot 2101 is opened inside the second fixing ring 21. The width of the first slot 2101 is greater than the width of the first limiting groove 22. The diameter of the first fixing ring 2 is smaller than the diameter of the second fixing ring 21, so that the second limiting block 26 can slide in the first slot 2101.

[0021] The first fixing ring 2 has a plurality of evenly distributed second limiting grooves 23 and third limiting grooves 24. The second limiting grooves 23 are located on the side closer to the second fixing ring 21 and the third limiting grooves 24 are arranged through the second fixing ring 21. The third limiting grooves 24 are located on the side away from the second fixing ring 21 and the second fixing ring 21 passes through the first fixing ring 2. The width of the second limiting grooves 23 is greater than the width of the third limiting grooves 24.

[0022] The second limiting groove 23 is provided with a second limiting block 26, and the third limiting groove 24 is provided with a first limiting block 25. The second limiting groove 23 and the second limiting block 26 are configured to cooperate with each other, and the third limiting groove 24 and the first limiting block 25 are configured to cooperate with each other. The first limiting block 25 and the second limiting block 26 are integrally formed. The first limiting block 25 has a through second slot 2501 on the side near the second fixing ring 21, and the annular spring 2201 is installed in the second slot 2501. The second limiting block 26 has a third slot 2601 on the side away from the second fixing ring 21. Multiple evenly arranged second rotating shafts 2602 are rotatably arranged in the third slot 2601. The second rotating shafts 2602 are arranged parallel to the first fixing ring 2. The arrangement of the second rotating shafts 2602 can reduce the friction between the second limiting block 26 and the steel coil during the temporary fixing process.

[0023] One side of the annular spring 2201 is fixedly connected to one end of the second limiting block 26, and the annular spring 2201 near one end of the second limiting block 26 is fixedly connected to the side wall of the second slot 2501.

[0024] When the first limiting block 25 and the second limiting block 26 slide towards the second fixed ring 21 within the third limiting groove 24 and the second limiting groove 23, the annular spring 2201 is in an extended state.

[0025] First, the small steel coils to be bundled are placed on conveyor belt 1. Because conveyor belt 1 has raised patterns 15, the friction between the steel coils and conveyor belt 1 is increased, making it easier for the small steel coils to be conveyed on conveyor belt 1. When the small steel coils are conveyed to the first fixing ring 2, the second limiting block 26 drives the first limiting block 25 to slide towards the second fixing ring 21. Under the action of the ring spring 2201, the second limiting block 26 clamps the small steel coils. At this time, the second limiting block 26 temporarily fixes the small steel coils. The steel coils continue to be conveyed to the other side of conveyor belt 1, where a bundling machine performs bundling work on the small steel coils. Because one end of the steel coil is continuously fixed by the second limiting block 26, the tension on the other end during bundling is balanced by the clamping force of the fixed end, preventing radial rolling of the steel coils during bundling. This ensures accurate bundling position and uniform tension of the packing strap, meeting the force requirements of subsequent warehousing and transportation.

[0026] The second limiting block 26 temporarily fixes the steel coil during the bundling process. On the one hand, it can prevent the steel coil from accidentally rolling or tipping over and hitting the operator or damaging the surrounding equipment. On the other hand, it can reduce the problem of "ineffective tightness" of the bundling strap: if the steel coil is not fixed, it may rotate slightly as the bundling strap tightens, resulting in insufficient actual tension of the bundling strap (it looks tight, but it is not actually attached to the steel coil), and it may loosen due to vibration during subsequent transportation.

[0027] Working principle: First, the small steel coils to be bundled are placed on conveyor belt 1. When the small steel coils are conveyed by conveyor belt 1 to the inside of the first fixing ring 2, the second limiting block 26 installed on the first fixing ring 2 will drive the first limiting block 25 to slide synchronously towards the second fixing ring 21. Under the pressure of the annular spring 2201, the second limiting block 26 has a temporary fixing effect on the steel coil. The second rotating shaft 2602 on the second limiting block 26 reduces the friction between it and the steel coil, facilitating the conveying action of the steel coil on conveyor belt 1. After the steel coil is temporarily fixed, the conveyor belt 1 continues to drive the steel coil to move to the other side of the conveyor belt 1. When one end of the steel coil is still temporarily fixed by the first fixing ring 2, the other end enters the bundling work area. During this process, since one end of the steel coil is continuously fixed by the second limiting block 26, the tension on the other end during bundling will be balanced by the clamping force of the fixed end, which completely avoids axial movement or radial rolling of the steel coil during bundling, ensuring accurate bundling position and uniform tension of the packing strap. The resulting bundling structure is firm and reliable, and can meet the stress requirements of subsequent warehousing and transportation.
