For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figures 1 to 5 As shown, the steel strip decoiler 100 of the present invention includes a support assembly 1, a support release assembly 2 fixed on the support assembly 1 to support the steel coil and drive the steel coil to rotate, and a pressing assembly 3 fixed on the support assembly 1 to press the steel coil.

[0026] like Figures 2 to 5As shown, the support assembly 1 includes a support platform 11, a mounting platform 12 fixedly arranged on the support platform 11 and extending upward in the height direction, two bearing seats 13 fixed on the mounting platform 12, and a support rod 14 extending upward in the vertical direction.

[0027] The support platform 11 is used to be placed on the ground and is generally formed by welding a plurality of rectangular steels. A support panel 15 is formed on the upper surface of the support platform 11 .

[0028] The mounting platform 12 is welded to the support platform 11 to support the support release assembly 2. A support hole 121 is provided through the mounting platform 12. A lifting lug 122 is welded to the top of the mounting platform 12 to facilitate lifting equipment. The mounting platform 12 is formed from square tubes welded to the design dimensions.

[0029] The support rod 14 is fixed to the support platform 11 by welding.

[0030] The two bearing seats 13 are fixedly arranged on both sides of the mounting platform 12 respectively.

[0031] like Figure 3 and Figure 4 As shown, the support release assembly 2 includes a release motor 21 , a pulley 22 connected to the release motor 21 , a rotating shaft 23 connected to the pulley 22 , and a support member 24 arranged at one end of the rotating shaft 23 away from the pulley 22 .

[0032] The rotating shaft 23 passes through the bearing seat 13 , and the bearing seat 13 is fixed on the mounting platform 12 .

[0033] The release motor 21 is fixed to the support panel 15 by screws. One end of the pulley 22 is connected to the release motor 21 and is driven to rotate by the release motor 21. The other end of the pulley 22 is connected to the rotating shaft 23 to drive the rotating shaft 23 to rotate. The rotating shaft 23 passes through the support hole 121.

[0034] The support member 24 includes a turntable 241 fixed to the rotating shaft 23, a rotating drum 242 mounted on the turntable 241, a first support plate 243 fixed on the rotating drum 242, a second support plate 244 arranged on the side of the first support plate 243 away from the rotation, a rotating plate 245 pivotally connecting the first support plate 243 and the second support plate 244, and a driving member 246 for driving the rotating drum 242 to move axially.

[0035] The turntable 241 is disposed at one end of the rotating drum 242 close to the release motor 21 , that is, along the axial direction, the turntable 241 is disposed between the mounting platform 12 and the rotating drum 242 , and the mounting platform 12 is located between the release motor 21 and the turntable 241 .

[0036] In this embodiment, an avoidance groove 2421 is radially provided on the rotating cylinder 242, and an anti-rotation screw 231 is provided on the rotating shaft 23. The anti-rotation screw 231 passes through the avoidance groove 2421, so that the rotating cylinder 242 can move axially relative to the rotating shaft 23, and the anti-rotation screw 231 can prevent the rotating cylinder 242 and the rotating shaft 23 from rotating relative to each other.

[0037] The first support plate 243 protrudes radially outward from the rotating drum 242 .

[0038] The second support plate 244 is radially arranged outside the first support plate 243. The second support plate 244 has a first state close to the first support plate 243 and a second state away from the first support plate 243. The steel coil is a hollow columnar structure. When the steel coil is placed, the second support plate 244 is in the second state. At this time, it is easy to put the steel coil on the second support plate 244. When the steel coil needs to be rotated and released, the second support plate 244 is in the second state. At this time, the second support plate 244 moves outward a distance to support the steel coil.

[0039] The rotating plate 245 is pivotally connected to both the first support plate 243 and the second support plate 244. In this embodiment, when the second support plate 244 is in the first state, the rotating plate 245 is tilted relative to the axis, while when the second support plate 244 is in the second state, the rotating plate 245 is perpendicular to the axis. Of course, in other embodiments, the rotating plate 245 can also be tilted when the second support plate 244 is in the first state and the second state, but the tilt angle in the second state is greater than the tilt angle in the first state.

[0040] One end of the second support plate 244 axially extends through the turntable 241 and is provided with a retaining member 247 to prevent the second support plate 244 from disengaging from the turntable 241. When the second support plate 244 switches from the first state to the second state, the retaining member 247 abuts against the turntable 241, thereby enabling the second support plate 244 to move. In this embodiment, the retaining member 247 is a shaft extending along the circumference of the turntable 241. The turntable 241 is provided with a radial groove to enable the second support plate 244 to move when switching between the first and second states.

[0041] In this embodiment, the number of the first support plate 243, the second support plate 244 and the rotating plate 245 is multiple, each first support plate 243 and the second support plate 244 are connected by two rotating plates 245 to form a group, and the multiple first support plates 243 are arranged in an array along the circumferential direction.

[0042] The driving member 246 includes a driving handle 2461 and a sleeve 2462 mounted on the rotating shaft 23. The sleeve 2462 is located at the end of the rotating drum 242 away from the turntable 241. The driving handle 2461 is threadedly connected to the rotating shaft 23 to drive the sleeve 2462 to rotate, and the sleeve 2462 is radially abutted against the rotating drum 242. By rotating the driving handle 2461, the sleeve 2462 is driven to rotate, and then the rotating drum 242 is driven to move, thereby realizing the switching between the first state and the second state of the second support plate 244.

[0043] like Figure 5 As shown, the clamping assembly 3 includes a driving cylinder 31, an adjusting screw 32 driven by the driving cylinder 31, a connecting plate 33 pivotally connected to the support assembly 1 at one end, a pressure roller 34 connected to the other end of the connecting plate 33, a fixing plate 36, and a connecting shaft 35 fixed to the connecting plate 33.

[0044] The support rod 14 is fixed on the mounting platform 12 or the support platform 11. A pivot shaft 37 is provided at the upper end of the support rod 14, and the connecting plate 33 is pivotally connected to the support rod 14 via the pivot shaft 37.

[0045] The connecting plate 33 is provided with a movable groove 331 along its length, into which the adjusting screw 32 is inserted. The axis of the pressing roller 34 is parallel to the axis of the steel coil, and the axis of the pressing roller 34 is perpendicular to the connecting plate 33. The connecting plate 33 is tilted so that when the adjusting screw 32 moves within the movable groove 331, it can drive the ballast roller 34 to move along the radial direction of the steel coil, thereby achieving the effect of pressing the steel coil.

[0046] The fixing plate 36 is fixedly connected to the adjusting screw 32 and the driving cylinder 31 .

[0047] The pressing roller 34 is sleeved on the connecting shaft 35 . A limiting shaft is provided on a side of the pressing roller 34 away from the connecting plate 33 to prevent the pressing roller 34 from being separated from the connecting shaft 35 .

[0048] The working process of the steel strip decoiler 100 of the present invention is as follows: when the steel coil needs to be decoiled, the steel coil is first transferred to the support release assembly 2 with the assistance of a crane or a forklift, and then the driving handle 2461 is rotated manually or by a device, so that the second support plate 244 is turned from the first state to the second state to radially support the steel coil;

[0049] The release motor 21 drives the pulley 22 to rotate, and then drives the rotating shaft 23, the rotating drum 242, the first support plate 243, the rotating plate 245 and the second support plate 244 to rotate, thereby driving the steel coil to rotate. At the same time, the driving cylinder 31 works to drive the adjusting screw 32, the connecting plate 33 and the pressure roller 34 to move, so as to press the steel coil tightly and prevent the steel coil from unwinding. The belt transmission is driven by the release motor 21 to control the rotation of the steel coil and cut the length of the steel strip as needed.

[0050] The steel strip uncoiler 100 of the present invention drives the steel strip coil to rotate by supporting and releasing the assembly 2, thereby reducing the labor of the operator during the operation, improving the efficiency of the steel strip coil cutting operation, and avoiding safety hazards.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
