Companies need equipment capable of automated, high-precision processing to improve production efficiency, reduce costs, and enhance product quality.

[0003] Traditional rewinding machines often encounter several problems during the rewinding of sheet materials. Existing rewinding trays use a fixed installation structure, preventing flexible rotation and adjustment of the sheet material during rewinding. This lack of rotation significantly reduces operator flexibility, increasing operational difficulty and potentially leading to decreased rewinding quality. Furthermore, the fixed structure restricts rewinding efficiency, resulting in a longer overall process and impacting production efficiency and economic benefits.

[0004] Therefore, this utility model provides a rewinding and unloading rotary device to solve the above problems. Utility Model Content

[0027] 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.

[0028] This utility model provides a rewinding and unwinding rotary device, such as... Figure 1-5 As shown, the rewinding and unloading rotary device includes a device base 1, a tilting frame 2 rotatably mounted on the upper end of the device base 1, a hydraulic telescopic rod 3 fixedly mounted on the right side of the device base 1, the telescopic end of the hydraulic telescopic rod 3 being connected to the tilting frame 2, a first tray 4 fixedly mounted on the upper end of the tilting frame 2, a bearing seat 5 fixedly mounted on the upper side of the first tray 4, a rotating platform 6 mounted on the upper side of the bearing seat 5, a first drive motor 7 fixedly mounted on the lower side of the first tray 4, a reduction motor 8 fixedly mounted on the output shaft of the first drive motor 7, the rotating platform 6 being connected to the reduction motor 8, and a limit component being provided on the first tray 4.

[0029] During use, the operator can control the extension and retraction of the hydraulic telescopic rod 3 to move it, thereby driving the flipping frame 2 to flip from the center at the upper end of the device base 1, opening the limit component, so that the first drive motor 7 and the reduction motor 8 drive the rotating platform 6 to rotate, thereby realizing the flexible rotation and adjustment of the copper tube coil, improving the operator's flexibility when handling the copper tube coil, reducing the difficulty of operation, and improving the rewinding quality.

[0030] The limiting component includes a second drive motor 10, which is fixedly installed on the lower left side of the first tray 4. The output shaft of the second drive motor 10 is fixedly installed with a first screw 11. The upper end of the first screw 11 is threadedly connected to a limiting pin 12. Multiple sets of positioning holes 13 are opened in the inner ring of the rotating platform 6.

[0031] In use, the output shaft of the second drive motor 10 rotates the first screw 11, causing the first screw 11 to rotate and drive the limit pin 12 to slide up and down, so that the limit pin 12 can be inserted into multiple sets of positioning holes 13, thereby limiting and fixing the rotating platform 6 through multiple sets of positioning holes 13 to prevent the rotating platform 6 from rotating.

[0032] A roll material positioning shaft 9 is fixedly installed on the upper side of the rotating platform 6, and the roll material positioning shaft 9 is located at the axis on the upper side of the rotating platform 6.

[0033] The setting of the roll positioning shaft 9 makes it easy for operators to fix the copper tube roll and facilitates the rewinding of the rotating platform 6, thus improving the practicality of the rotating device.

[0034] The upper edge of the limiting pin 12 and the lower opening edge of the multiple positioning holes 13 are both arc-shaped, and the outer diameter of the limiting pin 12 matches the inner diameter of the multiple positioning holes 13.

[0035] The arc-shaped design allows the limiting pin 12 to be smoothly inserted into the multiple positioning holes 13, thereby improving the practicality of the limiting component. At the same time, by matching the outer diameter of the limiting pin 12 with the inner diameter of the multiple positioning holes 13, the tightness between the limiting pin 12 and the multiple positioning holes 13 is further improved, preventing the limiting pin 12 from falling out of the multiple positioning holes 13, thereby improving the stability of the limiting component.

[0036] A limit frame 14 is fixedly installed on the left side of the device base 1. Synchronous pulleys 15 are symmetrically installed in the limit frame 14. Synchronous belts 16 are sleeved on the two sets of synchronous pulleys 15. A second screw 17 is fixedly installed on each of the two sets of synchronous pulleys 15. A protective frame 18 is threadedly sleeved on the upper end of the two sets of second screws 17.

[0037] During use, the two sets of synchronous pulleys 15 and synchronous belts 16 rotate, which in turn drives the two sets of second screws 17 to rotate. This causes the protective frame 18 to move up and down with the rotation of the two sets of second screws 17, making it easier for operators to limit the copper tube coil and prevent the copper tube coil from shifting during rotation, thus improving the safety of the rotating device.

[0038] The upper end of the protective frame 18 is higher than the upper side of the rotating platform 6, and the length of the two sets of second screws 17 is greater than the height of the protective frame 18.

[0039] The protective frame 18 further enhances the limiting effect on the copper tube coil. At the same time, the length of the two sets of second screws 17 is greater than the height of the protective frame 18, making the protective frame 18 more stable during up and down movement, preventing the protective frame 18 from shaking during rotation, and further improving the stability of the rotating device.

[0040] The inner wall of the protective frame 18 is bonded with a cushioning pad, which is composed of polyurethane elastomer.

[0041] The inclusion of a cushioning pad increases the flexibility of the inner wall of the protective frame 18, thus preventing damage to the copper tube coil when the protective frame 18 limits its movement and improving the practicality of the rotating device. Simultaneously, the polyurethane elastomer's excellent abrasion resistance, tear strength, and elasticity further extend the service life of the cushioning pad.

[0042] The upper part of the protective frame 18 is made of seamless steel pipe, and the surface of the protective frame 18 is provided with warning yellow and black stripes.

[0043] The use of seamless steel pipes enhances the strength and stability of the protective frame 18, making it less prone to deformation or damage during use and further improving the durability of the rotating device. At the same time, the yellow and black warning stripes allow operators to clearly see the position of the protective frame 18, improving safety during operation and preventing collisions between operators and the protective frame 18, thus ensuring operator safety.

[0044] A notch is provided on the upper left side of the protective frame 18, and the lower side of the notch is flush with the upper side of the rotating platform 6.

[0045] The notch design makes it easier for operators to place the copper tube coil on the rotating platform 6. At the same time, the lower side of the notch is flush with the upper side of the rotating platform 6, which makes the copper tube coil more stable during rotation and prevents it from slipping off the rotating platform 6, thus further improving the safety of the rotating device.

[0046] The surface of the roll positioning shaft 9 is provided with a filler pad, which is made of rubber.

[0047] The addition of a filler pad increases the flexibility of the surface of the coil positioning shaft 9, preventing the surface of the coil positioning shaft 9 from scratching the edges of the copper tube coil when the operator places it on the coil positioning shaft 9. This further improves the practicality of the rotating device. At the same time, the rubber material has good elasticity and wear resistance, which increases the service life of the filler pad.

[0048] Working principle: In use, the operator first places the copper tube coil on the coil positioning shaft 9, which initially limits the copper tube coil. When the copper tube coil rotates, the operator can rotate the two sets of synchronous pulleys 15 and synchronous belt 16, which drives the two sets of second screws 17 to rotate. This causes the protective frame 18 to move up and down with the rotation of the two sets of second screws 17, further limiting the copper tube coil. Then, the operator can control the extension and retraction of the hydraulic telescopic rod 3, which drives the flipping frame 2 to flip from the center of the device base 1. The operator can control the output shaft of the second drive motor 10 to rotate the first screw 11, which drives the limit pin 12 to slide up and down until the limit pin 12 slides out from the multiple positioning holes 13. This ensures the smooth progress of the entire rewinding process, allowing the first drive motor 7 and the reduction motor 8 to drive the rotating platform 6 to rotate, thereby realizing the flexible rotation and adjustment of the copper tube coil.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
