DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings.

[0020] Combined with Figure 1, An aluminum coil unwinding device for facilitating the replacement of aluminum coils, comprising a mounting plate 1, a moving part 2 fixedly connected to one side of the mounting plate 1 for moving the unwinding position, and an unwinding part 3 fixedly connected to one side of the moving part 2 for unwinding the coil.

[0021] The present utility model will be further described below in conjunction with embodiments.

[0022] Embodiment 1:

[0023] Please refer to Figure 1 and Figure 2 , the unwinding part 3 includes a motor 31 fixedly connected to one side of the moving part 2, a rotating shaft 32 fixedly connected to the output end of the motor 31, springs 33 fixedly connected to both sides of the rotating shaft 32, telescopic rods 34 fixedly connected to both sides of the rotating shaft 32, a supporting part 5 fixedly connected to the upper end of the telescopic rod 34 for supporting the aluminum coil, the spring 33 is fixedly connected to the supporting part 5, the moving part 2 includes a slide rail 21 fixedly connected to one side of the mounting plate 1, a slider 22 slidably connected inside the slide rail 21, a telescopic cylinder 23 fixedly connected to the inner wall of the slide rail 21, the telescopic end of the telescopic cylinder 23 is fixedly connected to the slider 22, and the slider 22 is fixedly connected to the motor 31.

[0024] Specifically, before installing the aluminum coil, the telescopic cylinder 23 extends, driving the slider 22 to slide downward in the slide rail 21, so that the height of the slider 22 decreases, making the height of the unwinding part 3 lower, saving the force required for installing the aluminum coil and facilitating the subsequent installation of the aluminum coil. When the unwinding height needs to be adjusted, the telescopic end of the telescopic cylinder 23 expands and contracts, driving the slider 22 to slide in the slide rail 21. After adjusting to the required height, the telescopic cylinder 23 stops running to fix the height. When the aluminum coil needs to be fixed, the telescopic rod 34 expands and contracts, adjusts the length according to the size of the aluminum coil, so that the supporting part 5 can support the inner wall of the aluminum coil, and the spring 33 is in a compressed state, playing a role of supporting and buffering for the supporting part 5. When unwinding is required, the motor 31 operates, driving the rotating shaft 32 to rotate, so that the aluminum coil supported by the supporting part 5 rotates for unwinding, realizing the unwinding of aluminum coils of different sizes, and the elastic force of the spring 33 plays a supporting role, which can reduce the vibration during rotation.

[0025] Embodiment 2:

[0026] Please refer to Figures 1 - 3 , the supporting part 5 includes arc blocks 51 fixedly connected to the relatively outer sides of two groups of telescopic rods 34, a sliding groove 52 is opened on one side of the arc block 51, a fixed rod 53 is fixedly connected to the inner wall of the sliding groove 52, two groups of balls 54 are rotatably connected inside the sliding groove 52, the balls 54 are fixedly connected in two groups, the fixed rod 53 passes through the two groups of balls 54 and is rotatably connected to the balls 54, and a limiting plate 4 is threadedly connected to one side of the rotating shaft 32.

[0027] Specifically, during the installation of the aluminum coil on the support portion 5, due to the certain weight of the aluminum coil itself, it takes a great deal of effort to install the entire aluminum coil. When the aluminum coil comes into contact with the ball 54, the ball 54 will rotate during the movement process, reducing the frictional resistance between the aluminum coil and the arc block 51, facilitating the installation of the aluminum coil on the arc block 51, saving the force required for installation, and the limiting plate 4 can prevent the aluminum coil from being thrown out due to rotation during uncoiling.

[0028] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
