The drum is usually mounted on a fixed bearing seat, and the positions of the fixed plates on both sides remain unchanged to ensure the stability of the drum during the unwinding process.
[0004] Traditional unwinding mechanisms for color-coated aluminum coils suffer from inconsistent sizes of take-up and unwinding rollers used in different batches or specifications. When it is necessary to change to take-up and unwinding rollers of different sizes, it is often necessary to manually adjust the position of the fixing plate or replace the unwinding mechanism of different specifications. This operation is cumbersome, time-consuming, and labor-intensive, which seriously affects production efficiency. To address this issue, a new unwinding mechanism for color-coated aluminum coils is proposed. Utility Model Content

[0032] 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.
[0033] Reference Figures 1-3 This utility model provides an embodiment of an unwinding mechanism for color-coated aluminum coils, comprising a base 1, which provides a stable support platform for various components above it. A mounting plate 2 is fixedly connected to the upper surface of the base 1 for further installation and layout of other key components. A take-up / unwind roller 8, mounted on the upper surface of the mounting plate 2, is the core component for realizing the unwinding and rewinding operations of the color-coated aluminum coil. The aluminum coil is wound around the take-up / unwind roller 8, and the corresponding process is completed as the take-up / unwind roller 8 rotates. The sidewall of the take-up / unwind roller 8 is slidably connected inside a mounting sleeve 7, and the sidewall of the mounting sleeve 7 is rotatably connected to a fixed plate 6. An adjustment component on the upper surface of the mounting plate 2 plays a crucial adaptive adjustment role. The lower surface of a slide rail 3 is fixedly connected to the upper surface of the mounting plate 2, and a slider 4 is slidably connected to its sidewall. The slider 4 can slide smoothly along the slide rail 3, providing the basic motion conditions for subsequent spacing adjustment. The connecting plate 5, which is fixedly connected to the upper surface of slider 4, serves as a connection and transmission mechanism. The motor 9, which is fixedly connected to the side wall of the fixed plate 6 on one side, is the power source for the rotation of the take-up and untake-up rollers 8. The output end of the motor 9 is fixedly connected to the side wall of the mounting sleeve 7 on one side. After the motor 9 starts, it drives the take-up and untake-up rollers 8 to rotate, thereby realizing the unwinding or winding action of the aluminum coil and precisely controlling the unwinding and winding speed. The slide rail 11, which is fixedly connected to the upper surface of the mounting plate 2, is similar to the slide rail 3 and also provides a stable sliding track for other components. The slider 12, which is slidably connected to its side wall, can slide along the slide rail 11. A rotating plate 13 is rotatably connected to the upper surface of slider 12, with one end rotatably connected to the upper surface of connecting plate 5. A hydraulic rod 14 is fixedly connected to the upper surface of base 1, and the output end of hydraulic rod 14 is fixedly connected to the side wall of slider 12. By activating hydraulic rod 14, slider 12 is pushed to slide along slide rail 11. With the linkage of rotating plate 13, connecting plate 5 and other components, the spacing between fixed plates 6 is automatically adjusted according to the size of take-up and untake-up rollers 8, ensuring the adaptability of the entire unwinding mechanism to take-up and untake-up rollers 8 of different specifications. A sliding plate 10 is fixedly connected to the bottom of fixed plate 6, and its side wall is slidably connected inside mounting plate 2. The sliding plate 10 enhances the stability of fixed plate 6 during movement.
[0034] When it is necessary to disassemble or replace the take-up / delivery roller 8, firstly, the hydraulic rod 14 is activated. As a key drive component, the hydraulic rod 14 quickly initiates the retraction action upon receiving the retraction command, generating a strong pulling force at its output end, which directly acts on the rigidly connected slider 12. The sidewall of slider 12 is tightly fitted onto the slide rail 11, which provides an extremely smooth and precisely guided sliding track for slider 12. Under the pulling force of the hydraulic rod 14, slider 12 can slide smoothly and steadily along the slide rail 11. As slider 12 slides, the rotating plate 13, which is rotatably connected to the upper surface, begins to rotate. The rotating plate 13 acts like a clever transmission link, with one end flexibly rotatably connected to the upper surface of the connecting plate 5, cleverly converting the linear motion of slider 12 into a thrust on the connecting plate 5. Since the lower surface of the connecting plate 5 is fixedly connected to the slider 4, and the side wall of the slider 4 is attached to the slide rail 3, which also has a precise guiding function, it ensures that the slider 4 slides only in a predetermined direction. Therefore, the rotation of the rotating plate 13 pushes the slider 4 to slide outwards on the slide rail 3. The outward sliding of the slider 4 causes the connecting plate 5, which is fixedly connected to its upper surface, to move synchronously, thereby increasing the distance between the fixed plates 6. The fixed plates 6 play a crucial role in clamping and positioning in the entire device, and the mounting sleeve 7, which is rotatably connected to its side wall, is the direct load-bearing component of the take-up and release roller 8. When the distance between the fixed plates 6 increases, the fitting degree between the inner hole of the mounting sleeve 7, which was originally tightly fitted to the side wall of the take-up and release roller 8 and provided limiting and support for the roller 8, decreases, causing the take-up and release roller 8 to detach from the mounting sleeve 7. At this time, the take-up and release roller 8 loses its fixing effect and can be easily removed and replaced, thereby meeting different production needs and ensuring the continuity and flexibility of the production process.
[0035] Reference Figure 4The tension assembly includes a support frame 15, which provides a solid foundation for all key components within it, ensuring stable operation of the entire tension adjustment process. Inside the support frame 15 are a pressing roller 18 and a conveyor roller 19. The conveyor roller 19 plays a crucial role in material transport; when the color-coated aluminum coil is released from the unwinding mechanism, it first contacts the conveyor roller 19. The conveyor roller 19, through its rotation, smoothly transports the aluminum coil forward, preventing jamming or deviation. The pressing roller 18, working in conjunction with the conveyor roller 19, is responsible for adjusting the tension of the aluminum coil. The sidewall of the pressing roller 18 is rotatably connected inside a mounting cover 17, which is in turn tightly connected to an electric actuator 16. The electric actuator 16, fixedly connected to the upper surface of the support frame 15, serves as the direct power source for adjusting the position of the pressing roller 18. When the electric actuator 16 receives a command from the control system and starts, its output end drives the mounting cover 17 to move up and down. Since the pressing roller 18 is installed inside the mounting cover 17, its vertical position can be adjusted accordingly. The mounting cover 17 is fixedly connected to the side wall of the fixing block 20, and the support frame 15 has two sliding grooves 22 and 23 inside. The side wall of the fixing block 20 is slidably connected inside the sliding groove 22. This ensures that when the mounting cover 17 moves under the drive of the electric push rod 16, it can only slide vertically up and down along the direction defined by the sliding groove 22, effectively preventing the mounting cover 17 from shifting laterally or shaking. At the same time, the limiting block 21, which is fixedly connected to the side wall of the fixing block 20, is slidably connected inside the sliding groove 23, further enhancing the stability of the entire guiding system. The limiting block 21 not only assists the fixing block 20 in limiting the mounting cover 17, but also plays a secondary supporting and stabilizing role in the vertical direction. Even in long-term and frequent use, facing various vibrations and impacts, it can ensure the positional accuracy of the mounting cover 17 and the extrusion roller 18, and continuously and stably provide tension adjustment for the aluminum coil.
[0036] When using this equipment to wind up and unwind color-coated aluminum coils, the coil is first passed between the conveyor roller 19 and the extrusion roller 18. The conveyor roller 19, with its smooth and wear-resistant surface, provides a stable support point for the coil, ensuring a smooth transition when it initially enters the tension adjustment area and preventing scratches or jamming due to poor contact. Next, the motor 9 is started. As the core power source for the entire winding and unwinding operation, the powerful output of the motor 9 is transmitted to the mounting sleeve 7 via a rigid connection. Driven by the motor 9, the mounting sleeve 7 rotates rapidly. Because the sidewall of the winding and unwinding roller 8 is slidably connected inside the mounting sleeve 7, this tight and flexible connection allows the roller 8 to follow the rotation rhythm of the mounting sleeve 7, slowly winding up or unwinding the color-coated aluminum coil. During the winding and unwinding process, to ensure the aluminum coil tension remains optimal, it can be adjusted by activating the electric actuator 16. Upon receiving a command from the control system, the electric actuator 16 quickly activates, its output precisely pushing the mounting cover 17 downwards. The mounting cover 17, serving as the support component for the extrusion roller 18, directly drives the extrusion roller 18 closer to the aluminum coil during its downward movement. At this time, the fixing block 20 slides down inside the first slide groove 22, which provides a sliding track for the fixing block 20, ensuring that the moving direction of the mounting cover 17 is vertically downward and preventing lateral deviation, allowing the extrusion roller 18 to accurately apply pressure to the aluminum coil. Simultaneously, the limiting block 21 slides down inside the second slide groove 23, and the cooperation between the second slide groove 23 and the limiting block 21 further enhances the stability of the entire movement process. The limiting block 21 not only shares some of the weight of the mounting cover 17 in the vertical direction, reducing the pressure on the fixing block 20 and the first slide groove 22 and extending its service life, but also plays a crucial role in preventing the mounting cover 17 from shaking. When the extrusion roller 18 presses down on the aluminum coil, the frictional force on the aluminum coil increases, thereby changing the position of the pressure roller and adjusting the tension of the aluminum coil, so that the aluminum coil is tightened and straightened during unwinding, effectively preventing surface wrinkling. This tension adjustment mechanism can adapt to color-coated aluminum coils of different materials and thicknesses, greatly improving the versatility of the equipment and the quality stability of the produced products.
[0037] Working Principle: When using this equipment to wind up and unwind color-coated aluminum coils, the coil is first passed between the conveyor roller 19 and the extrusion roller 18. Then, the motor 9 is started, driving the mounting sleeve 7 to rotate, which in turn drives the take-up and unwind roller 8 to rotate, slowly winding up or unwinding the aluminum coil. During the winding and unwinding process, the electric push rod 16 can be activated to push the mounting cover 17 downwards, allowing the fixing block 20 to slide down inside the first slide groove 22, while the limiting block 21 slides down inside the second slide groove 23, thereby pressing down on the color-coated aluminum and changing its shape. The pressure roller position adjusts the aluminum coil tension, ensuring the coil is taut and straightened during unwinding to prevent surface wrinkling. When it is necessary to disassemble or replace the take-up / unwind roller 8, the hydraulic rod 14 is activated and retracted, thereby pulling the slider 12 to slide, causing the rotating plate 13 to rotate. This pushes the slider 4 to slide outward on the slide rail 3, increasing the distance between the fixing plates 6 and allowing the take-up / unwind roller 8 to disengage from the mounting sleeve 7. At this point, the take-up / unwind roller 8 loses its fixing effect and can be removed for replacement.
[0038] 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.
