Description

Technical Field

[0001] This utility model relates to the field of packing strap winding technology, and in particular to a galvanized packing strap winding device. Background Technology

[0002] In the production and processing of galvanized strapping, winding is a crucial step. Its main function is to neatly and orderly wind up the finished galvanized strapping for subsequent storage, transportation, and use. With the continuous development of industrial production, the application range of galvanized strapping is becoming increasingly wide, and the requirements for its production efficiency and winding quality are also increasing. To meet the needs of different scenarios, galvanized strapping comes in various specifications, which places higher demands on the adaptability of winding devices. A galvanized strapping winding device that can flexibly adjust winding parameters has become an urgent need in the industry to ensure smooth production processes and improve overall production efficiency. In existing technologies, common galvanized strapping winding devices typically consist of a fixed drum, a drive motor, a transmission mechanism, and simple guide components. The technical principle is that the drive motor provides power, which is transmitted to the fixed drum via the transmission mechanism, causing the drum to rotate. Simultaneously, the galvanized strapping, guided by the guide components, gradually winds around the outer wall of the drum, completing the winding operation. This type of device has a relatively simple structure, relying mainly on the fixed rotation speed and fixed dimensions of the drum to achieve winding. It was once widely used in scenarios where winding requirements were not high and production scale was small. However, existing winding devices often use drums with a fixed diameter. This results in a significant limitation on the winding length when the galvanized strapping is wound to a certain extent and reaches the drum's maximum capacity, as the winding diameter cannot be adjusted. At this point, the operator must stop the winding operation, replace the drum, or unload the fully wound strapping before restarting the device to continue winding. Therefore, this paper proposes a galvanized strapping winding device to solve the aforementioned problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a galvanized strapping winding device, which aims to improve the problem in the prior art where the fixed diameter leads to limited winding length, requiring frequent replacement of the roll or machine shutdown for unloading, thus reducing production efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A galvanized packing strap winding device includes a support column and a bracket. The support column is provided with a bracket on its side wall, a bearing is fixedly connected to the top of the support column, a drive assembly is provided on the side wall of the support column, a hollow column is rotatably connected to the side wall of the bearing, a cylinder is fixedly connected inside the hollow column, a fixing ring is fixedly connected to the output end of the cylinder, and an unfolding assembly is provided on the outer wall of the fixing ring. The unfolding assembly includes a third connecting block, the side wall of which is fixedly connected to the outer wall of the fixing ring. A second rotating rod is rotatably connected to the side wall of the third connecting block. A fourth connecting block is rotatably connected to the inner wall of the second rotating rod. A clamping plate is fixedly connected to the side wall of the fourth connecting block. A second connecting block is fixedly connected to the inner wall of the clamping plate. A first rotating rod is rotatably connected to the side wall of the second connecting block. A first connecting block is rotatably connected to the inner wall of the first rotating rod. The side wall of the first connecting block is fixedly connected to the outer wall of the hollow column.

[0005] As a further description of the above technical solution: The drive assembly includes a first motor, the sidewall of which is rotatably connected to the sidewall of the support column, and a chain assembly fixedly connected to the output end of the first motor, the sidewall of which is rotatably connected to the sidewall of the bearing.

[0006] As a further description of the above technical solution: A rotating roller is fixedly connected to the top of the bracket, a support frame is fixedly connected to the inner wall of the bracket, a rotating shaft is fixedly connected inside the support frame, and a first collar is fixedly connected to the side wall of the support frame.

[0007] As a further description of the above technical solution: A second motor is fixedly connected to the inner wall of the first ring, and a worm gear is fixedly connected to the output end of the second motor.

[0008] As a further description of the above technical solution: A worm gear is rotatably connected to the outer wall of the rotating shaft, and the worm meshes with the worm gear.

[0009] As a further description of the above technical solution: A slider is fixedly connected to the side wall of the support frame, and a toothed column is slidably connected to the side wall of the slider.

[0010] As a further description of the above technical solution: A gear is rotatably connected to the outer wall of the rotating shaft, and the gear meshes with the toothed column.

[0011] As a further description of the above technical solution: One end of the toothed column is fixedly connected to a second ring, and the inner wall of the second ring is rotatably connected to the outer wall of the rotating roller.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the fixed ring is driven to move by a cylinder, and then the movement of the fixed ring drives the third connecting block on the outer wall to move. At the same time, it drives the second rotating rod and the fourth connecting block to rotate, which in turn drives the clamping plate to move. Simultaneously, the movement of the clamping plate drives the second connecting block on the side wall to rotate. The second connecting block drives the first rotating rod and the first connecting block to rotate together, thereby achieving the effect of adjusting the winding diameter. This solves the problem that the fixed diameter leads to the limited winding length, requiring frequent replacement of the roll or machine stoppage for unloading, which reduces production efficiency and improves the convenience of the galvanized strapping winding device. 2. In this utility model, the first ring drives the worm to rotate, the worm drives the worm wheel to rotate, and then the worm wheel drives the internal rotating shaft to rotate. Next, during the rotation of the rotating shaft, the gear on the outer wall is driven to rotate. Then, the gear drives the toothed column to move, and the movement of the toothed column drives the second ring at one end to move. At the same time, the second ring drives the rotating roller to move up and down, which achieves the effect of adjusting the tension. This solves the problem that uneven tension causes uneven tightness, wrinkling, deformation, and even edge warping when the strapping is wound, affecting the appearance and performance of the product. It also improves the stability of the galvanized strapping winding device. Attached Figure Description

[0015] 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.

[0016] Reference Figures 1-3 This utility model provides an embodiment of a galvanized packing strap winding device, including a support column 4 and a bracket 1. The bracket 1 is provided on the side wall of the support column 4, and a bearing 6 is fixedly connected to the top of the support column 4. A driving component is provided on the side wall of the support column 4. A hollow column 17 is rotatably connected to the side wall of the bearing 6. A cylinder 18 is fixedly connected inside the hollow column 17. The cylinder 18 is used to drive the fixed ring 22 to move axially, thereby driving the unfolding component to expand or contract the clamping plate 26, achieving the purpose of adjusting the winding diameter, adapting to the winding requirements of packing straps of different lengths, and improving the versatility and flexibility of the device. The output end of the cylinder 18 is fixedly connected to the fixed ring 22, and an unfolding component is provided on the outer wall of the fixed ring 22. The unfolding assembly includes a third connecting block 23, the side wall of which is fixedly connected to the outer wall of the fixing ring 22. A second rotating rod 24 is rotatably connected to the side wall of the third connecting block 23. A fourth connecting block 25 is rotatably connected to the inner wall of the second rotating rod 24. A clamping plate 26 is fixedly connected to the side wall of the fourth connecting block 25. The clamping plate 26 is used to clamp one end of the galvanized strapping, thereby achieving initial fixation of the strapping and preventing the strapping from loosening or falling off in the early stage of winding, thus improving the stability and continuity of the winding process. A second connecting block 21 is fixedly connected to the inner wall of the clamping plate 26. A first rotating rod 20 is rotatably connected to the side wall of the second connecting block 21. A first connecting block 19 is rotatably connected to the inner wall of the first rotating rod 20. The side wall of the first connecting block 19 is fixedly connected to the outer wall of the hollow column 17.

[0017] Reference Figures 4-6The drive assembly includes a first motor 3, whose sidewall is rotatably connected to the sidewall of the support column 4. A chain assembly 5 is fixedly connected to the output end of the first motor 3, and the sidewall of the chain assembly 5 is rotatably connected to the sidewall of the bearing 6. A rotating roller 2 is fixedly connected to the top of the support 1. A support frame 15 is fixedly connected to the inner wall of the support 1. A rotating shaft 14 is fixedly connected inside the support frame 15. A first collar 7 is fixedly connected to the sidewall of the support frame 15. A second motor 8 is fixedly connected to the inner wall of the first collar 7. A worm gear 9 is fixedly connected to the output end of the second motor 8. A worm wheel 10 is rotatably connected to the outer wall of the rotating shaft 14. The worm gear 9 and the worm wheel 10 mesh and transmit power, thereby driving the rotating shaft 14 to rotate. This achieves the effect of driving the gear 11 to rotate, providing the power basis for the linear motion of the gear column 12. The worm 9 meshes with the worm wheel 10. The side wall of the support frame 15 is fixedly connected to the slider 16, and the side wall of the slider 16 is slidably connected to the gear column 12. The outer wall of the rotating shaft 14 is rotatably connected to the gear 11. The gear 11 and the gear column 12 mesh and transmit power, so that the gear column 12 can move up and down under the limit of the slider 16, achieving the effect of adjusting the height of the rotating roller 2, thereby realizing the dynamic control of the tension of the packing tape. The gear 11 meshes with the gear column 12, and one end of the gear column 12 is fixedly connected to the second ring 13. The inner wall of the second ring 13 is rotatably connected to the outer wall of the rotating roller 2.

[0018] Working principle: When this galvanized strapping winding device is in operation, the first motor 3 starts, and its output end drives the chain assembly 5 to rotate. The chain assembly 5 transmits power to the bearing 6, causing the hollow column 17, which is rotatably connected to the bearing 6, to start rotating. At this time, the cylinder 18 inside the hollow column 17 is in its initial state, and the clamping plates 26 in the unfolding assembly are in a retracted state, which can fix one end of the galvanized strapping between the clamping plates 26. As the hollow column 17 continues to rotate, the strapping gradually wraps around the outer surface of the roll formed by multiple clamping plates 26, realizing the winding operation. When the winding diameter needs to be adjusted, the output end of the cylinder 18 pushes the fixed ring 22 to move. The fixed ring 22 drives the third connecting block 23 on the outer wall to move synchronously, causing the second rotating rod 24 to rotate around the third connecting block 23 as the fulcrum. This, in turn, pushes the clamping plate 26 to expand outward through the fourth connecting block 25. At the same time, the second connecting block 21 on the clamping plate 26 drives the first rotating rod 20 to rotate around the first connecting block 19 as the fulcrum, helping the clamping plate 26 maintain a stable expansion trajectory, ultimately increasing the winding diameter to meet the needs of winding longer packing tapes. The diameter adjustment can be completed without stopping the machine.

[0019] During the winding process, the device can ensure the flat winding of the strapping by means of a tension adjustment mechanism: after the second motor 8 starts, its output end drives the worm gear 9 to rotate, and the worm wheel 10 meshing with the worm gear 9 rotates accordingly, thereby driving the rotating shaft 14 passing through the support frame 15 to rotate synchronously. When the rotating shaft 14 rotates, the gear 11 on its outer wall rotates accordingly, and the toothed column 12 meshing with the gear 11 moves in a straight line under the limiting action of the slider 16. The second ring 13 at one end of the toothed column 12 pushes the rotating roller 2 up and down. By adjusting the height of the rotating roller 2, the tension of the strapping in the winding path can be changed. When the rotating roller 2 rises, the tension of the strapping increases and the winding is tighter. When the rotating roller 2 falls, the tension decreases, avoiding deformation of the strapping due to excessive stretching. This effectively prevents problems such as uneven tension, wrinkling, or edge warping during the winding process, ensuring the winding quality and appearance integrity of the galvanized strapping.

[0020] 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.
