Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper foil, in particular to an unwinding mechanism of a surface treatment machine. Background Art

[0002] In the field of electrolytic copper foil technology, surface treatment machines are one of the key devices used to treat the surface of copper foil. In these devices, the unwinding mechanism is used to support and guide the unwinding of the copper foil roll to facilitate subsequent processing.

[0003] Traditional unwinding mechanisms are usually designed to adapt to reel shafts of specific specifications. For example, reel A has a small bearing diameter, narrow width, and short bearing center distance. This design limits the versatility and flexibility of the unwinding mechanism. However, with the diversification of industrial production needs, it is necessary to process copper foil rolls of different specifications, which requires the unwinding mechanism to be able to adapt to reel shafts of different specifications. For example, reel B has a larger bearing diameter, wide width, and long bearing center distance, which makes the traditional unwinding mechanism unable to adapt directly. When reel B is needed, it cannot be placed in the unwinding mechanism because its size does not match the unwinding mechanism, which leads to reduced production efficiency and insufficient equipment utilization. In addition, once the existing unwinding mechanism is fixed, it is difficult to adjust to adapt to reel shafts of different specifications. This not only limits the flexibility of the equipment, but also increases production costs, because it may be necessary to purchase and maintain multiple sets of unwinding mechanisms for different reel shaft specifications.

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1-3 As shown, the utility model provides a surface treatment machine unwinding mechanism, comprising:

[0027] Base 1;

[0028] Support frame 1 2 and support frame 2 3 are arranged at two ends of the base 1 opposite to each other, and bearing seats 4 are arranged on the support frame 1 2 and support frame 2 3 opposite to each other;

[0029] The unwinding shaft 5 has two ends rotatably arranged in the bearing seat 4 through bearings 100;

[0030] An adjustment mechanism is provided between the base 1 and the support frame 1 2 and is used to adjust the position of the support frame 1 2 to adjust the distance between the support frame 1 2 and the support frame 2 3 to accommodate unwinding shafts 5 of different lengths.

[0031] In this embodiment, the bearing seat 4 is provided with an opening, which is rotatably connected to a flip plate 6 for limiting the position of the unwinding shaft 5 in the bearing seat 4. The opening design allows the unwinding shaft 5, when large or heavy, to be placed into or removed from the bearing seat 4 by rolling, thereby quickly adapting to reeling shafts of different specifications while maintaining ease of operation and reliability of the equipment.

[0032] Furthermore, a locking device is provided at the opening of the bearing seat 4 for locking the flip plate 6 after it has been flipped into place. The locking device is used to ensure that the flip plate 6 is securely locked after being adjusted to the appropriate position to accommodate unwinding shafts of different specifications. This design improves the flexibility and adaptability of the unwinding mechanism while also ensuring safety and reliability during operation.

[0033] Preferably, the locking device is a buckle. The flip plate 6 is provided with a slot adapted to the buckle.

[0034] Furthermore, guide plates 12 are provided on the support frame 1 2 and the support frame 2 3. The guide plates 12 are arranged opposite to the bearing seat 4 and are used to guide the unwinding shaft 5 during its rolling process toward the bearing seat 4. The design of the guide plates 12 makes the replacement and maintenance of the unwinding shaft 5 more convenient and quick, thereby improving production efficiency and equipment utilization.

[0035] In this embodiment, a groove 121 is provided in the middle of the guide plate 12, and the width of the groove 121 is adapted to the bearings 100 at both ends of the unwinding shaft 5. The groove 121 serves as a sliding path for the bearing 100, and can maintain the correct alignment and positioning of the bearing 100 and the bearing seat 4.

[0036] In this embodiment, the second support frame 3 is fixedly connected to the base 1, and a triangular support is provided between the second support frame 3 and the base 1. The stability and load-bearing capacity of the second support frame 3 are enhanced by adding the triangular support.

[0037] Furthermore, an adjustment mechanism for adjusting the position of the support frame 1 2 is provided between the base 1 and the support frame 1 2 , and is used to adjust the distance between the support frame 1 2 and the support frame 2 3 to accommodate unwinding shafts 5 of different lengths.

[0038] Specifically, the adjustment mechanism includes a sliding plate 7, a servo motor 8, and a screw 9. The servo motor 8 is disposed on the base 1. The output shaft of the servo motor 8 is connected to one end of the screw 9, and the other end of the screw 9 is connected to the sliding plate 7 via an adjustment seat. The design of the adjustment mechanism enables rapid switching of unwinding shafts 5 of different specifications, reduces downtime caused by changing the specifications of the unwinding shaft 5, and improves the flexibility and response speed of the production line.

[0039] In addition, a linear slide rail 10 is provided between the sliding plate 7 and the base 1 , and sliders 11 adapted to the linear slide rail 10 are provided at both ends of the sliding plate 7 .

[0040] In this embodiment, the base 1 has a U-shaped structure. Due to its symmetry and wide base support, the U-shaped structure provides a large contact area and a low center of gravity, helping to enhance the stability of the entire base 1 and reduce vibration and movement caused by load or operation. Furthermore, the U-shaped design can better disperse and withstand forces in various directions, such as vertical pressure and lateral forces, thereby improving the structural strength of the base 1.

[0041] The unwinding mechanism of the surface treatment machine based on the above embodiment can adapt to winding shafts of various specifications, so that the same equipment can be used to process products of various specifications, thereby improving the utilization rate and production flexibility of the equipment and improving the utilization rate of the equipment; in addition, the improved unwinding mechanism can quickly switch winding shafts of different specifications, reducing the preparation and adjustment time when replacing the winding shaft, and improving production efficiency.

[0042] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
