Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel coil production technology, specifically to a steel coil strapping collection device. Background Technology
[0002] In many fields such as steel production, processing, and logistics, steel coils are a common product, and their bundling is crucial. Steel coil strapping, as a key component used to secure steel coils and prevent them from unwinding, needs to be collected and organized using specialized collection devices after the bundling task is completed, so as to facilitate subsequent storage, transportation, and recycling.
[0003] Traditional steel coil strapping collection devices suffer from numerous technical defects in practical applications, severely impacting production efficiency and strapping collection quality. Currently, common traditional steel coil strapping collection devices employ a design where the strapping passes horizontally through the winding head. In this structure, one end of the strapping extends shorter than the other. When the winding head begins winding, the shorter end, lacking effective fixation and support, easily slips out during the winding process. Once this happens, the winding operation fails, forcing operators to reposition the strapping and restart the winding process. This not only wastes significant time and labor costs but also severely disrupts the continuity of the entire production process, leading to a substantial reduction in production efficiency.
[0004] In addition, traditional devices lack sufficient guidance and restraint for the strapping during the winding process, making it difficult to ensure that the strapping enters the winding head stably and smoothly. This can easily lead to problems such as strapping tangling and loose winding, which further affects the quality of strapping collection and increases the risk of strapping loosening and damage during subsequent storage and transportation. It also brings inconvenience to the recycling of strapping. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the prior art by providing a steel coil strapping collection device that can effectively prevent the strapping from slipping out, improve winding efficiency and quality, and ensure smooth production processes.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A steel coil strapping collection device includes a base with a vertical mounting plate and a first linear drive assembly and a second linear drive assembly located on the left and right sides of the mounting plate, respectively, for relative movement. The first linear drive assembly is connected to a winding drive device, which is connected to a rotatable winding head. The mounting plate has a through hole for the winding head to pass through. The second linear drive assembly is connected to a push plate, which is parallel to and opposite to the mounting plate. An extrusion drive device is connected to the upper end of the mounting plate, which is connected to a vertically lifting extrusion head. A clamping and feeding assembly is provided on the front side of the mounting plate. The clamping and feeding assembly includes a fixed frame, a movable frame, a first clamping roller, a second clamping roller, and a clamping drive device. The fixed frame is connected to the base, one end of the movable frame is rotatably connected to the fixed frame, the first clamping roller is rotatably connected horizontally to the fixed frame, the second clamping roller is rotatably connected to the movable frame, and one end of the clamping drive device is connected to the fixed frame and the other end is connected to the movable frame, for driving the two clamping rollers to clamp and open.
[0008] Furthermore, a horizontal fixing plate is connected to one side of the mounting plate, the fixing plate is provided with a winding groove connected to the through hole, and the push plate is slidably connected to the upper side of the fixing plate; the push plate is provided with a clearance hole to avoid the extrusion head.
[0009] Furthermore, the fixing plate has downwardly inclined wing plates on its front and rear sides, and the push plate has side plates on its front and rear sides, with the lower end of the side plate slidingly contacting the corresponding wing plate.
[0010] Furthermore, the winding head has a cylindrical structure, and one end of the winding head is provided with a radially penetrating opening groove for the strapping to pass through.
[0011] Furthermore, the take-up head is provided with a baffle plate, and the first linear drive assembly is connected to a photoelectric detection sensor for detecting the position of the baffle plate.
[0012] Furthermore, the first linear drive assembly includes a first drive cylinder and a first slide. One end of the first drive cylinder is connected to the machine base, and the other end is connected to the first slide. The first slide is slidably connected to the upper surface of the machine base via a linear guide rail. The winding drive device is connected to the first slide. The second linear drive assembly includes a second drive cylinder and a second slide. One end of the second drive cylinder is connected to the machine base, and the other end is connected to the second slide. The second slide is slidably connected to the upper surface of the machine base via the linear guide rail. The push plate is connected to the second slide.
[0013] Furthermore, the upper surface of the second slide is also provided with a pad for cooperating with the extrusion head to extrude and fix the strapping.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By using the clamping design of the first clamping roller and the second clamping roller in the clamping and feeding assembly, the long end of the strapping is clamped before winding, providing a stable foundation for winding. This fundamentally solves the problem of the short end of the strapping easily slipping out, avoids winding failure caused by the strapping slipping out, and significantly improves the winding success rate.
[0016] The push plate and mounting plate work together to form a slit and apply pressure, making the strapping tightly adhere to a disc shape, thus avoiding loosening during winding. The first and second clamping rollers passively rotate during winding to release the long end of the strapping and provide guiding force, ensuring that the strapping is smoothly fed into the winding head and improving winding smoothness. After winding, the extrusion head presses down to flatten the strapping into a dense state, preventing it from loosening due to elastic rebound. Through the cooperation of these designs, the quality of strapping collection is significantly improved, and the risk of loosening and damage to the strapping during subsequent storage and transportation is reduced.

[0028] Traditional steel coil strapping collection devices suffer from numerous technical defects in practical applications, severely impacting production efficiency and strapping collection quality. Currently, common traditional steel coil strapping collection devices employ a design where the strapping passes horizontally through the winding head. In this structure, one end of the strapping extends shorter than the other. When the winding head begins winding, the shorter end, lacking effective fixation and support, easily slips out during the winding process. Once this happens, the winding operation fails, forcing operators to reposition the strapping and restart the winding process. This not only wastes significant time and labor costs but also severely disrupts the continuity of the entire production process, leading to a substantial reduction in production efficiency.
[0029] In addition, traditional devices lack sufficient guidance and restraint for the strapping during the winding process, making it difficult to ensure that the strapping enters the winding head stably and smoothly. This can easily lead to problems such as strapping tangling and loose winding, which further affects the quality of strapping collection and increases the risk of strapping loosening and damage during subsequent storage and transportation. It also brings inconvenience to the recycling of strapping.
[0030] To address the above technical problems, this application provides a steel coil strapping collection device, including a base 1, a vertical mounting plate 2, and a first linear drive assembly and a second linear drive assembly located on the left and right sides of the mounting plate 2, respectively, capable of relative motion. The first linear drive assembly is connected to a winding drive device 3, which is connected to a rotatable winding head 4. The mounting plate 2 has a through hole for the winding head 4 to pass through. The second linear drive assembly is connected to a push plate 5, which is parallel to and opposite to the mounting plate 2. A compression drive device 6 is connected to the upper end of the mounting plate 2. The extrusion drive device 6 is connected to the vertically lifting extrusion head 7; the front side of the mounting plate 2 is provided with a clamping and feeding assembly, which includes a fixed frame 8, a movable frame 9, a first clamping roller 10, a second clamping roller 11, and a clamping drive device 12; the fixed frame 8 is connected to the machine base 1, one end of the movable frame 9 is rotatably connected to the fixed frame 8, the first clamping roller 10 is rotatably connected to the fixed frame 8, the second clamping roller 11 is rotatably connected to the movable frame 9, one end of the clamping drive device 12 is connected to the fixed frame 8, and the other end is connected to the movable frame 9, which is used to drive the two clamping rollers to clamp and open.
[0031] During operation, the movable frame 9 of the clamping and feeding assembly separates from the fixed frame 8 under the action of the clamping drive device 12. The first clamping roller 10 and the second clamping roller 11 open in a V-shape. The operator places the strapping horizontally on the first clamping roller 10 of the fixed frame 8, with the shorter end horizontal and the longer end naturally extending to the outside of the clamping roller. Then, the clamping drive device 12 pushes the movable frame 9 to close, so that the second clamping roller 11 and the first clamping roller 10 clamp the long end of the strapping. The first linear drive assembly pushes the winding drive device 3 to move towards the mounting plate 2, driving the winding head 4 through the through hole of the mounting plate 2 to the predetermined position, so that the groove in the middle of the winding head 4 passes through the short end of the strapping and begins to wind. During winding, the second linear drive assembly pushes the push plate 5 close to the mounting plate 2, forming a slit to restrict the strapping. The pressure of the push plate 5 makes the strapping tightly adhered to a disc shape. The first clamping roller 10 and the second clamping roller 11 passively rotate to release the long end of the strapping and provide guiding force to ensure that the strapping is smoothly fed into the winding head 4. After winding is completed, the first linear drive component pulls the winding drive device 3 backward, the winding head 4 disengages from the strapping roll, and the extrusion drive device 6 pushes the extrusion head 7 down to flatten the disc-shaped strapping into a dense state.
[0032] This embodiment of the steel coil strapping collection device solves the problem of traditional devices where the short end of the strapping easily slips out during winding, leading to winding failure and low efficiency. The clamping design of the first clamping roller 10 and the second clamping roller 11 in the clamping and feeding assembly ensures that the long end of the strapping will not slip during winding, providing a foundation for stable winding. The push plate 5 and the mounting plate 2 cooperate to form a narrow slit and apply pressure, making the strapping tightly adhere to a disc shape, preventing loose winding and improving the quality of strapping collection. The passive rotation and guiding action of the first clamping roller 10 and the second clamping roller 11 during the winding process ensures that the strapping is smoothly fed into the winding head 4, improving winding smoothness. After winding, the extrusion head 7 presses down to flatten the strapping into a dense state, preventing elastic rebound and loosening, facilitating subsequent storage and transportation. Through the coordinated work of all components, the efficiency and quality of steel coil strapping collection are greatly improved.
[0033] In some embodiments, a horizontal fixing plate 13 is connected to one side of the mounting plate 2. The fixing plate 13 is provided with a winding groove 14 connected to the through hole. The push plate 5 is slidably connected to the upper side of the fixing plate 13. The push plate 5 is provided with a clearance hole 15 for clearance of the extrusion head 7.
[0034] During the strapping winding operation, the push plate 5 is slidably connected to the upper side of the fixed plate 13. As the winding head 4 begins to wind the short end of the strapping that passes through the central groove, the strapping gradually coils under the action of winding force. At this time, the winding groove 14 acts as a limit for the coiled strapping, guiding the strapping to form a coiled shape and orderly position within the winding groove 14 along its trajectory.
[0035] The take-up groove 14 limits the strapping, ensuring that the strapping is coiled in a pre-set pattern within the take-up groove 14 during the take-up process, thus preventing the strapping from becoming messy or deviating from the predetermined position during take-up.
[0036] In some embodiments, the front and rear sides of the fixing plate 13 are respectively provided with downwardly inclined wing plates 16, and the front and rear sides of the push plate 5 are respectively provided with side plates 17, the lower end of the side plate 17 slidingly contacts the corresponding wing plate 16.
[0037] The downward-sloping wing plates 16 on the front and rear sides of the fixed plate 13 cooperate with the side plates 17 on the front and rear sides of the push plate 5. When the second linear drive assembly pushes the push plate 5 to slide on the upper side of the fixed plate 13, the lower end of the side plate 17 will always maintain sliding contact with the corresponding wing plate 16 to prevent the push plate 5 from shifting or shaking, and ensure the smooth operation of the extrusion.
[0038] In some embodiments, the winding head 4 is a cylindrical structure, and one end of the winding head 4 is provided with a radially penetrating opening groove 18 for the strap to pass through.
[0039] Since the winding head 4 has a radially penetrating opening slot 18 at one end, the operator can place the shorter end of the strap horizontally. During the process of the first linear drive assembly pushing the winding drive device 3 to drive the winding head 4 through the through hole of the mounting plate 2 to reach the predetermined position, the strap horizontally passes through the opening slot 18, so that the winding head 4 can start winding smoothly.
[0040] In some embodiments, the take-up head 4 is provided with a baffle 19, and the first linear drive assembly is connected to a photoelectric detection sensor 20 for detecting the position of the baffle 19.
[0041] The photoelectric detection sensor 20 continuously emits light signals and receives reflected light signals. After winding is completed, it starts to detect the position of the baffle 19. When the baffle 19 is detected to have reached the predetermined position, the photoelectric detection sensor 20 sends a signal to the control system to brake the winding drive device 3 and keep the opening slot 18 in a horizontal state, so that the opening slot 18 can pass through the strapping for the next use.
[0042] In some embodiments, the first linear drive assembly includes a first drive cylinder 21 and a first slide 22. One end of the first drive cylinder 21 is connected to the base 1, and the other end is connected to the first slide 22. The first slide 22 is slidably connected to the upper surface of the base 1 via a linear guide rail 23. The winding drive device 3 is connected to the first slide 22. The second linear drive assembly includes a second drive cylinder 24 and a second slide 25. One end of the second drive cylinder 24 is connected to the base 1, and the other end is connected to the second slide 25. The second slide 25 is slidably connected to the upper surface of the base 1 via a linear guide rail 23. The push plate 5 is connected to the second slide 25.
[0043] When the take-up head 4 needs to be moved to the predetermined position, the piston rod of the first drive cylinder 21 extends and retracts, pushing the first slide table 22 to slide smoothly along the linear guide rail 23, thereby driving the take-up drive device 3 and the take-up head 4 to move together, so that the take-up head 4 accurately passes through the through hole of the mounting plate 2 to reach the take-up starting position. During the strapping take-up process, the piston rod of the second drive cylinder 24 extends and retracts, pushing the second slide table 25 to slide along the linear guide rail 23, driving the push plate 5 to move closer to the mounting plate 2, forming a slit with the mounting plate 2, and squeezing and restricting the strapping; after the take-up is completed, the second drive cylinder 24 reverses its action, pulling the second slide table 25 and the push plate 5 back to their original positions.
[0044] In some embodiments, the upper end surface of the second slide 25 is further provided with a pad 26 for cooperating with the extrusion head 7 to extrude and fix the strapping.
[0045] After the strapping is wound up and forms a disc-shaped structure, the pad 26 and the extrusion head 7 form a corresponding compressive force, tightly squeezing and fixing the strapping between the pad 26 and the extrusion head 7. During this process, the pad 26 can evenly distribute the pressure applied by the extrusion head 7, ensuring that the force on each part of the strapping is balanced, thereby achieving effective flattening and fixing of the strapping and preventing the strapping from loosening due to elastic rebound.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
