Description

Technical Field

[0001] The utility model belongs to the technical field of steel coil unwinding, and in particular relates to an unwinding device capable of continuously supplying steel strips. Background Art

[0002] In metal processing, sheet metal processing and highly automated production lines, the steel strip unwinder plays a pivotal role, and its importance is self-evident. It undertakes the important task of gradually unwinding the tightly wound steel strip in a smooth and uninterrupted manner, providing a steady supply of materials for subsequent processing. However, the design limitations of traditional steel strip unwinding devices have gradually emerged, especially the commonly used single expansion drum configuration, which has significantly restricted the improvement of production efficiency.

[0003] The limitation of a single expansion drum is that it requires the production line to stop running after each coil is unrolled in order to replace the new coil. This process not only interrupts the continuity of production, but also increases the time and cost of manual operation. More importantly, every time a new coil is placed on the unwinder and ready to be unrolled, the external binding tape must be cut off manually. This step is not only time-consuming and labor-intensive, but also poses a potential safety hazard that cannot be ignored, because during the operation, workers may face the risk of being scratched by sharp binding tape or being caught in the machine.

[0004] Therefore, it is very necessary to invent a uncoiler that can continuously supply steel strip. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a uncoiler capable of continuously supplying steel strips, comprising a continuous supply uncoiler, an uncoiler auxiliary support machine and a stable guide rail seat, wherein the continuous supply uncoiler is rotatably mounted on the uncoiler auxiliary support machine, and the continuous supply uncoiler and the uncoiler auxiliary support machine are respectively fixed to the stable guide rail seat;

[0006] The continuous supply uncoiler comprises a driving support seat, a continuous driving motor, a continuous carrying disc and an expansion reel, wherein the driving support seat is fixed to a stable guide rail seat, an output end of the continuous driving motor fixedly mounted outside the driving support seat is fixed to the continuous carrying disc, the continuous carrying disc is rotatably mounted on the uncoiler auxiliary support machine, and a plurality of expansion reels rotatably mounted on the continuous carrying disc are respectively fixed to the output end of the motor fixedly mounted on the continuous carrying disc;

[0007] The uncoiling auxiliary support machine includes a bearing support seat, a high-torque motor, a drive shaft, a cutting arm, a pressing arm, a support body, a pressing roller, and a holding arm. The continuous load-bearing disk is rotatably installed in the bearing support seat, and the bearing support seat is fixed to the stable guide rail seat. Two high-torque motors are rotatably installed on the outer surface of the bearing support seat. The output ends of the two high-torque motors are respectively fixed to the two drive shafts. The cutting arm or the pressing arm is fixedly installed on the two drive shafts. A support body is fixedly installed between the cutting arms, and the pressing roller is rotatably installed. A high-torque motor is fixedly installed on the cutting arm, and the output end of the high-torque motor is fixed to one end of the holding arm.

[0008] Preferably, there are two stable guide rail seats in total. The stable guide rail seats are "L"-shaped guide rail seats. The two stable guide rail seats are arranged in parallel. The two stable guide rail seats are used to provide a moving path for the loading cart.

[0009] Preferably, at least two expansion drums are installed on the continuous load-bearing disk. The expansion drums are distributed in a circular array. The continuous load-bearing disk is installed with motors corresponding to the number of expansion drums. The motors are used to drive the expansion drums to rotate. A holding cylinder is rotatably installed at the end face of the expansion drum.

[0010] Preferably, the holding arm is located outside one of the pressing arms. One end of the holding arm is provided with a semi-circular concave area matching the outer surface of the holding cylinder. When the holding arm moves in an arc trajectory, it does not interfere with the expansion drum and the fixing steel belt of the expansion drum.

[0011] Preferably, the two drive shafts are respectively arranged above the bearing support seat and on one side of the bearing support seat. The cutting arm is fixedly installed on the drive shaft at the upper position. A cutting knife head for cutting the binding tape is provided at the end of the cutting arm. Two pressing arms are fixedly installed on the drive shaft at the side position. The pressing roller is rotatably installed at the ends of the two pressing arms. When the pressing arm and the cutting arm move in an arc trajectory, they do not interfere with the expansion drum and the fixing steel belt of the expansion drum.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This utility model completely abandons the restraint of the traditional single expanding drum and innovatively introduces the design of multiple grouped expanding drums. It not only greatly expands the working space for the steel strip to unwind, but also realizes the seamless connection of the placement of a new steel coil while the steel coil is continuously unwinding, ensuring the continuity and high efficiency of the production process and completely eliminating the drawback of downtime required for replacing the steel coil. In addition, the uncoiler auxiliary support machine integrates highly intelligent functions and can automatically complete the pressing task during the unwinding process of the steel coil without direct manual intervention, ensuring the smooth output of the steel strip. This auxiliary support machine is also equipped with an automatic binding tape cutting mechanism, which can quickly and accurately cut the external binding tape before the steel coil is ready to unwind. This not only significantly improves the operation efficiency, but also fundamentally reduces the safety risks faced by workers due to handling sharp binding tapes, providing a solid guarantee for the safety of the production environment and the health of workers.

[0021] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0022] An uncoiler for continuously supplying a steel strip provided by the present invention includes a continuous supply uncoiler 1, an uncoiling auxiliary support machine 2, and a stable guide rail seat 3. The continuous supply uncoiler 1 is rotatably installed on the uncoiling auxiliary support machine 2, and the continuous supply uncoiler 1 and the uncoiling auxiliary support machine 2 are respectively fixed to the stable guide rail seat 3.

[0023] Furthermore, the continuous supply uncoiler 1 includes a driving support seat 11, a continuous driving motor 12, a continuous bearing disc 13, and an expansion drum 14. The driving support seat 11 is fixed to the stable guide rail seat 3. The output end of the continuous driving motor 12 fixedly installed outside the driving support seat 11 is fixed to the continuous bearing disc 13. The continuous bearing disc 13 is rotatably installed on the uncoiling auxiliary support machine 2. A plurality of the expansion drums 14 rotatably installed on the continuous bearing disc 13 are respectively fixed to the output ends of the motors fixedly installed on the continuous bearing disc 13.

[0024] Further, the uncoiling auxiliary support machine 2 includes a bearing support base 21, a high-torque motor 22, a drive shaft 23, a cutting arm 24, a pressing arm 25, a support body 26, a pressing roller 27, and a holding arm 28. The continuous bearing disc 13 is rotatably installed in the bearing support base 21, and the bearing support base 21 is fixed to the stable guide rail base 3. Two high-torque motors 22 are rotatably installed on the outer surface of the bearing support base 21. The output ends of the two high-torque motors 22 are respectively fixed to the two drive shafts 23. The cutting arm 24 or the pressing arm 25 is fixedly installed on the two drive shafts 23. A support body 26 is fixedly installed between the cutting arms 24, and the pressing roller 27 is rotatably installed. A high-torque motor 22 is fixedly installed on the cutting arm 24, and the output end of this high-torque motor 22 is fixed to one end of the holding arm 28.

[0025] Further, two "L"-shaped guide rail bases are provided for the stable guide rail base 3, and they are arranged in parallel, jointly constituting the moving path of the loading cart. This design not only ensures the stability of the loading cart during the transportation of the steel coil, but also simplifies the operation process and improves the production efficiency through clear path guidance. At the same time, the structural design of the "L"-shaped stable guide rail base 3 also enhances the stability of the overall equipment, providing a solid foundation for the continuous operation of the steel strip uncoiling machine.

[0026] Further, in order to further improve the continuous operation ability of the steel strip uncoiling machine, at least two expansion drums 14 are installed on the continuous bearing disc 13, and the arrangement of these expansion drums 14 follows a specific logic. One of the expansion drums 14 is always located above, serving as the steel coil unwinding station, and another expansion drum 14 is correspondingly arranged directly below, serving as the steel coil placement station. Such a layout ensures that while one steel coil is being unwound, another steel coil can be smoothly placed in place, realizing the seamless connection of the production process. In addition, the expansion drums 14 are distributed in a circular array, which is both beautiful and practical, improving the space utilization rate. Each expansion drum 14 is equipped with an independent motor to drive its rotation to ensure the smooth output of the steel strip. At the same time, a holding cylinder is rotatably installed on the end face of the expansion drum 14 to further enhance the fixing effect on the steel coil.

[0027] Further, in the uncoiling auxiliary support machine 2, the holding arm 28 is located outside one of the pressing arms 25, and a semi-circular concave area matching the outer surface of the holding cylinder is specially designed at one end. This design enables the holding arm 28 to precisely cooperate with the holding cylinder when performing an arc-shaped trajectory movement, without any interference with the expansion drum 14 or the steel strip fixed on the expansion drum 14, thus ensuring the smoothness and safety of the entire uncoiling process.

[0028] Furthermore, the layout of the drive shaft 23 on the bearing support base 21 has also been carefully planned. A cutting arm 24 is fixedly installed on the drive shaft 23 at the upper position, and a sharp cutting tool head is installed at its end for quickly cutting off the binding tape outside the steel coil. On the drive shaft 24 at one side position, two pressing arms 25 are installed, and a pressing roller 27 is rotatably installed at the common end of the two pressing arms 25. When the pressing arm 25 and the cutting arm 24 move along their respective arc trajectories, they also follow the principle of not interfering with the expansion reel 14 and the steel strip, ensuring the accuracy and efficiency of the cutting and pressing operations. This collaborative working mechanism greatly improves the automation level of the steel strip uncoiler, reduces the need for manual intervention, and thus also reduces potential safety hazards.

[0029] The working principle is as follows: First, when the uncoiling device for continuously supplying the steel strip of the present utility model starts to work, the loading cart moves along the two parallel "L"-shaped stable guide rail seats 3, and accurately places the steel coil to be unwound at the designated position of the continuous supply uncoiler 1. This step ensures the stability and safety of the steel coil during transportation and placement, simplifies the operation process, and improves production efficiency.

[0030] Then, the drive support base 11 of the continuous supply uncoiler 1 starts to work through the continuous drive motor 12 fixed outside it. The output end of the drive motor 12 is connected to the continuous bearing plate 13, driving the entire bearing plate to rotate. A number of expansion reels 14 are installed on the continuous bearing plate 13, and these expansion reels 14 are driven to rotate by their respective independent motors to prepare to receive and unwind the steel coil.

[0031] Next, during the rotation of the continuous bearing plate 13, the expansion reel 14 at the upper position starts to work as the steel coil unwinding station. The continuous bearing plate 13 in the bearing support base 21 of the uncoiling auxiliary support machine 2 rotates stably, and the two high-torque motors 22 outside the bearing support base 21 respectively drive the two drive shafts 23. The two pressing arms 25 on the drive shaft 23 at one side position start to work. The pressing roller 27 rotatably installed at the end of the pressing arm 25 presses the steel coil to ensure the stability of the steel coil during unwinding. At the same time, under the drive of another high-torque motor 22, the semi-circular concave area of the supporting arm 28 precisely cooperates with the supporting cylinder on the expansion reel 14, further enhancing the fixing effect of the steel coil and preventing deviation or slipping during unwinding.

[0032] Subsequently, after the pressing roller 27 and the supporting arm 28 complete their restrictive tasks. The cutting arm 24 on the drive shaft 23 at the upper position is activated, and the cutting tool head at its end quickly cuts off the binding tape outside the steel coil to prepare for the unwinding of the steel coil.

[0033] Finally, when the steel coil on the upper expanding reel 14 is gradually unwound and supplied to the subsequent process, the lower expanding reel 14 serves as the steel coil placement station, ready to receive a new steel coil. In this way, while one steel coil is being unwound, another steel coil can be seamlessly placed in position, achieving continuous operation of the steel strip uncoiler. Throughout the process, each component works in coordination without interference, ensuring the high efficiency, stability, and safety of the steel strip uncoiling.

[0034] Any technical solution using the technical solution described in the present utility model, or any technical solution designed by those skilled in the art inspired by the technical solution of the present utility model and achieving the above technical effects, shall fall within the protection scope of the present utility model.
