[0026] As shown in Figure 1 , 2 , lifting assembly 21 is one of the lifting structure of motor, screw or hydraulic cylinder lifting structure; support frame 3 is slidingly connected on the outer side wall of frame 2 and cooperatively connected with lifting assembly 21 in the inside of frame 2; the outer side wall of support frame 3 is also bolted with one end of reinforcing rod 31; the other end of reinforcing rod 31 is slidingly connected on the outer side wall of frame 2; in this embodiment, if lifting assembly 21 adopts the lifting structure of motor and screw, the rotation of motor drives the rotation of screw, due to the cooperation between screw and support frame 3, the rotary motion of screw is converted into the linear lifting motion of support frame 3; if it is a hydraulic cylinder lifting structure, the hydraulic oil in the hydraulic cylinder pushes the piston to move, the piston is connected with support frame 3 to drive support frame 3 to lift; the lifting of support frame 3 can adjust the height position of clamping shaft assembly 41 to adapt to steel coils of different diameters and the use of steel coils from the moving tool;

[0027] The clamping shaft assembly 41 is connected with the frame 2 through the support frame 3 and can rotate around the connecting point of the support frame 3 under the action of the driving device 4; the driving device 4 can be a power source such as a motor, which transmits power to the clamping shaft assembly 41 through a transmission mechanism such as a belt, a chain or a gear, so that the clamping shaft assembly 41 rotates; when the steel coil is installed, the steel coil is sleeved on the clamping shaft assembly 41, and the rotation of the clamping shaft assembly 41 can drive the steel coil to rotate to realize the unwinding action, wherein the clamping shaft has a diameter adjusting function and can abut against the inner diameter of the steel coil; the existing technology has similar technology, so it will not be described here.

[0028] The reinforcing rod 31 is connected at one end to the outer side wall of the support frame 3 and at the other end to the outer side wall of the frame 2 in a sliding manner; the principle is that when the support frame 3 is lifted and bears the weight of the steel coil and the force generated by rotation, the reinforcing rod 31 plays a role in strengthening the structural strength of the support frame 3 to prevent the support frame 3 from deforming.

[0029] In this embodiment, the height of the support frame 3 is adjusted by the lifting assembly 21, so that the clamping shaft assembly 41 is at a suitable height position. Then the steel coil is sleeved on the clamping shaft assembly 41, and the driving device 4 is started to drive the clamping shaft assembly 41 to rotate, and the steel coil rotates to perform the unwinding operation.

[0030] As shown in Figure 1 , 2 , the pressing wheel 54 is made of hard rubber; in this embodiment, the hydraulic device drives the hydraulic rotating shaft 52 to rotate in the bracket 51, and the rotation of the hydraulic rotating shaft 52 drives the pressing rod 53 fixed to the outer side wall thereof to move; since the other end of the pressing rod 53 is rotationally connected with the pressing wheel 54, the rotation of the hydraulic rotating shaft 52 will cause the pressing rod 53 to swing, thereby adjusting the distance between the pressing wheel 54 and the outer side wall of the steel coil; the pressing wheel 54 is made of hard rubber, which has a certain hardness and can exert sufficient pressure on the steel coil, and also has a certain elasticity to avoid damaging the surface of the steel coil; when the hydraulic device is started, the hydraulic oil drives the hydraulic rotating shaft 52 to rotate, and the hydraulic rotating shaft 52 drives the pressing rod 53 to swing, so that the pressing wheel 54 approaches and finally tightly adheres to the outer side wall of the steel coil; during the unwinding process of the steel coil, the pressing wheel 54 always maintains the pressing force on the steel coil; the pressing action of the pressing wheel 54 is controlled by the hydraulic device, so that the size of the pressing force can be accurately adjusted to adapt to steel coils of different materials; the pressing wheel 54 made of hard rubber can effectively press the steel coil to prevent it from loosening and also protect the surface of the steel coil to ensure the quality of the steel coil;

[0031] As shown in Figure 1 , 2As shown in the figure, the top of the platform 1 is bolted with a servo motor 62; the servo motor 62 is arranged between the frame 2 and the base 5; the output end of the servo motor 62 penetrates the base 5 and is connected with the connecting rod 61, which can directly control the rotation of the connecting rod 61; in this embodiment, two rotating frames 6 are arranged on the top of the platform 1, and the frame 2 and the base 5 are located between the two rotating frames 6; one end of the connecting rod 61 in each rotating frame 6 is rotationally connected with the rotating frame 6, and the other end is connected with the supporting shaft 71 through the connecting rod 7; when the steel coil is unwound, the connecting rod 61 can rotate around the connecting point with the rotating frame 6, and the supporting shaft 71 will also change its position accordingly under the driving of the connecting rod 61; the servo motor 62 on the platform 1 is arranged between the frame 2 and the base 5, and its output end penetrates the base 5 and is connected with the connecting rod 61; the servo motor 62 can accurately control the rotation angle and speed of the connecting rod 61; at the beginning of unwinding, the servo motor 62 is started, and according to the unwinding speed and the diameter of the steel coil and other parameters, the rotation angle and speed of the connecting rod 61 are controlled; the rotation of the connecting rod 61 drives the supporting shaft 71 to move, and the supporting shaft 71 plays a role of auxiliary support and guidance for the steel coil, so that the steel coil can be smoothly unwound during the unwinding process;

[0032] As shown in the figure, Figure 3 , 4 As shown in the figure, the limiting structure 8 includes an extension plate 81, a cushion block 82, a cylinder 83, a push rod 84, an extension frame 85, and a limiting wheel 86; the other side wall of the connecting rod 61 is integrally formed with the extension plate 81; the top of the extension plate 81 is bolted with the cushion block 82; the top of the cushion block 82 is bolted with the cylinder 83; one end of the push rod 84 is connected with the output end of the cylinder 83; the other end of the push rod 84 is bolted with the extension frame 85; the limiting wheel 86 is rotationally connected inside the extension frame 85; the limiting wheel 86 is a columnar structure with a concave outer side wall; the limiting wheel 86 is made of hard rubber; in this embodiment, the other side wall of the connecting rod 61 is integrally formed with the extension plate 81, which serves as a mounting base; the cushion block 82 is bolted on the top of the extension plate 81 to provide a stable mounting platform for the cylinder 83; the cushion block 82 is designed to be detachable, and different height cushion blocks 82 can be replaced as needed; the output end of the cylinder 83 is connected with the push rod 84, and the extension of the push rod 84 is controlled by the cylinder 83; the extension frame 85 is installed on the other end of the push rod 84, and the limiting wheel 86 is rotationally connected inside the extension frame 85; the limiting wheel 86 is a columnar structure with a concave outer side wall and is made of hard rubber; after the steel coil is opened, the cylinder 83 pushes the push rod 84 to extend, so that the limiting wheel 86 approaches the end of the steel coil that extends out; due to the concave shape and hard rubber material of the limiting wheel 86, it can tightly adhere to the side edge of the steel coil, which can exert a certain pressure on the steel coil to prevent it from exploding, and at the same time, it can limit the position of the extended part of the steel coil after rotation, avoiding the deviation of the steel coil.

[0033] Before the steel coil begins to unwind, cylinder 83 is in its initial state, and the limiting wheel 86 is away from the steel coil. When the steel coil begins to unwind and partially extends, cylinder 83 is activated, and push rod 84 pushes extension frame 85 to bring the limiting wheel 86 closer to the extended end of the steel coil, until the limiting wheel 86 is in close contact with the steel coil and begins to perform its limiting function. As the steel coil continues to unwind, the limiting wheel 86 continues to limit and compress the steel coil.

[0034] The implementation principle of this utility model embodiment is as follows:

[0035] like Figure 5 As shown, in use, the clamping shaft assembly 41 is first moved to a suitable position on the steel coil sleeve by the lifting component 21. After the clamping shaft 41 is driven to fix the steel coil, the lifting component 21 lifts the steel coil. Then, the hydraulic rotating shaft 52 rotates the clamping rod 53 to make the clamping wheel 54 press against the outer wall of the steel coil. Then, the steel coil binding strap is cut to achieve uncoiling. Then, the servo motor 62 is adjusted to rotate, so that the connecting rod 61 drives the limiting structure 8 to rotate to the part of the steel coil that has been opened and extended, until the steel coil can be placed on the support shaft 71. Then, the cylinder 83 is controlled to clamp the steel coil. Then, the position of the cylinder 83 is locked, and the extended end of the steel coil is guided into the equipment of the next process to start processing.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field, and those skilled in the art will understand them.
