[0026] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "disposed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figures 1 to 3 As shown, the steel coil winding and unwinding equipment of the utility model comprises: a base 1, on which a turntable 2 is rotatably mounted, and the turntable 2 is driven by a servo motor 3; a fixed shaft 4, which is mounted in the middle of the turntable 2; and a tightening member 5, which has at least two groups and is evenly distributed on the fixed shaft 4 with the axis of the fixed shaft 4 as the center.

[0030] See also Figure 1 , Figure 2 , Figure 3 The turntable 2 is circular, and the base 1 has a groove for accommodating the turntable 2. The turntable 2 is rotatably installed in the groove of the base 1; the servo motor 3 installed on the base 1 is used to drive the turntable 2 to rotate. The turntable 2 has a fixed shaft 4 in the middle of the surface on the side away from the servo motor 3. At least two tightening members 5 are installed on the fixed shaft 4. The multiple tightening members 5 can be tightened on the inner side of the steel coil 10, thereby fixing the steel coil 10.

[0031] When the steel coil 10 is unwound, the turntable 2 is controlled by the servo motor 3 to rotate on the base 1. The turntable 2 drives the fixed shaft 4 and the tightening member 5 to rotate synchronously, thereby realizing the unwinding of the steel coil 10 tightened on the tightening member 5. At the same time, the rotation speed of the turntable 2 is controlled by the servo motor 3, so that the relaxation degree of the steel coil 10 can be controlled, and the problem of loosening of the steel coil 10 due to excessive unwinding and scratching of the steel coil 10 can be effectively avoided, thereby improving the use effect of the present application and having practicality.

[0032] In one or more embodiments, a pushing component for expanding the tightening radius of the tightening member 5 is installed on the turntable 2 .

[0033] The pushing assembly includes: a pushing plate 61, which is arranged between the turntable 2 and the tightening member 5 and is fixed on the turntable 2 by a driving cylinder 62; a slide rail 63, which is installed on the pushing plate 61 on the side away from the turntable 2, and the slide rail 63 corresponds to the tightening member 5, and a slider 64 is slidably arranged on the slide rail 63; wherein, the tightening member 5 includes a rod portion 51 and a tightening portion 52 which are relatively rotatably connected, the rod portion 51 is rotatably installed on the fixed shaft 4, and the tightening portion 52 is hinged to the slider 64.

[0034] See also Figure 2 , Figure 3 It can be understood that the rod portion 51 and the tightening portion 52 included in the tightening member 5 are hinged, the rod portion 51 is hinged on the fixed shaft 4, and the tightening portion 52 is hinged to the slider 64, so that when the driving cylinder 62 pushes the push plate 61 to move away from the turntable 2, the slider 64 is squeezed and moves up on the slide rail 63, and the rod portion 51 tilted on the fixed shaft 4 can gradually tend to be vertical, so as to achieve: the radius range tightened by the several tightening portions 52 is increased; correspondingly, when it is necessary to reduce the radius range tightened by the tightening portion 52, the driving cylinder 62 is used to control the push plate 61 to move toward the turntable 2, the slider 64 is stretched and moves up and down on the slide rail 63, the inclination of the rod portion 51 is increased, and the radius range tightened by the several tightening portions 52 is reduced.

[0035] Through this arrangement, the present application can be adapted to steel coils 10 with different inner diameters, and at the same time, it is convenient to assemble the steel coil 10 on the tightening portion 52, which has strong operability and practicality.

[0036] In one or more embodiments, at least one group of the tightening members 5 is mounted with a clamping member 7 , and the clamping member 7 is detachably mounted on the tightening member 5 , and the clamping member 7 forms a limiting space for the steel coil 10 to be placed therein.

[0037] See also Figure 3 A clamping member 7 is installed on the tightening member 5, and the clamping member 7 has two members. The two clamping members 7 form a limiting space for limiting the side of the steel coil 10. Through this arrangement, it can be ensured that the steel strip is not prone to side shifting during the unwinding process of the steel coil 10.

[0038] It should be noted that, of the two clamping members 7 on each tightening member 5, the clamping member 7 located relatively on the outer side is detachably arranged. When the steel coil 10 needs to be installed on the tightening member 5, the clamping member 7 on that side needs to be removed first. After the steel coil 10 is installed on the tightening member 5, the clamping member 7 on that side can be installed on the tightening member 5.

[0039] In one or more embodiments, the clamping member 7 is mounted on the tightening member 5 by means of a quick-opening bolt. This arrangement enables quick installation of the clamping member 7, making it easier for the operator to operate.

[0040] In one or more embodiments, the clamping member 7 and the tightening member 5 are made of stainless steel. The clamping member 7 and the tightening member 5 made of stainless steel can prevent rust from contaminating the steel coil 10, thereby ensuring the safety of the steel coil 10 when it is unwound.

[0041] In one or more embodiments, the cross section of the clamping member 7 is a triangular structure. This arrangement can reduce the weight of the clamping frame while increasing the limiting range of the clamping member 7 on the side of the steel coil 10 .

[0042] In one or more embodiments, a limiting hole 8 is formed through the push plate 61 along the axial direction, and a polished rod 9 is installed on the rotating plate 2 corresponding to the limiting hole 8 , and the polished rod 9 extends into the limiting hole 8 .

[0043] See also Figure 2 , Figure 3 By setting the light rod 9 on the turntable 2 to extend into the limiting hole 8 of the push plate 61, the consistency of rotation of the push plate 61 and the turntable 2 can be further guaranteed, thereby avoiding the problem of change in the tightening radius of the tightening member 5 when the tightening member 5 tightens the steel coil 10.

[0044] In one or more embodiments, a rubber cushion is installed on the surface of the tightening part 52. The rubber cushion can change the contact mode between the tightening part 52 and the inner side of the steel coil 10, thereby reducing the wear on the steel coil 10 and the tightening member 5.

[0045] In one or more embodiments, a ball bearing is arranged between the turntable 2 and the base 1. This arrangement further reduces the friction between the turntable 2 and the base 1, and reduces the wear of the turntable 2.

[0046] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
