[0002] In modern industrial production, metal coils are a common form of raw materials, such as steel coils, aluminum coils, and iron coils, etc. They usually exist in a coiled form during storage and transportation. However, in the actual production process, it is necessary to unroll them for subsequent processing. In order to use these coiled materials in subsequent processing procedures, an uncoiler has become an essential device.

[0003] However, the existing uncoiler equipment has insufficient tension control ability for the coil, which results in uneven tension of the coil during the uncoiling process. For example, when the tension is too large, the coil may be overstretched or even broken; when the tension is too small, the coil may become loose and deviate, affecting the stability and accuracy of uncoiling, thereby reducing the product quality and production efficiency. In view of this, the steel coil uncoiling device of the present application is proposed. Summary of the Utility Model

[0034] As Figure 1 、 Figures 3 to 4 、 Figure 6 shown, in one embodiment, a steel coil uncoiling device 1 includes a frame 10, a rotating structure 20 and a clamping structure 30. The rotating structure 20 is arranged on the frame 10, and the rotating structure 20 is used to drive the coil to rotate.

[0035] It should be noted that the rotating structure 20 includes a rotating shaft 21, a pushing wheel 22, a main sleeve wheel 23, a clamping wheel 24, two secondary sleeve wheels 25, a plurality of connecting blocks 26 and a plurality of top blocks 27. One end of the rotating shaft 21 penetrates through the frame body 10. The pushing wheel 22, the main sleeve wheel 23 and the clamping wheel 24 are sequentially sleeved on the rotating shaft 21, and the pushing wheel 22 and the clamping wheel 24 jointly clamp the main sleeve wheel 23, so that the pushing wheel 22 drives the main sleeve wheel 23 and the clamping wheel 24 to slide relative to the rotating shaft 21. The two secondary sleeve wheels 25 are sleeved on the rotating shaft 21 and are located between the clamping wheel 24 and the frame body 10. In this way, the pushing wheel 22 drives the main sleeve wheel 23 to approach or move away from the secondary sleeve wheels 25. Further, a plurality of convex blocks are provided on the main sleeve wheel 23 and the two secondary sleeve wheels 25. Each convex block is distributed on the main sleeve wheel 23 and the secondary sleeve wheels 25 along the circumferential direction, and the number of convex blocks on the main sleeve wheel 23 and the two secondary sleeve wheels 25 is the same. Further, a rotating hole is provided on each convex block, and one end of each connecting block 26 is rotatably connected to the rotating hole. Further, three connecting holes are provided on any one of the top blocks 27, and the three connecting holes are respectively rotatably connected to the other ends of the connecting blocks 26 on the main sleeve wheel 23 and the two secondary sleeve wheels 25. Since a plurality of convex blocks are provided on the main sleeve wheel 23 and the secondary sleeve wheels 25, and the number of convex blocks on the main sleeve wheel 23 and the secondary sleeve wheels 25 is the same, a plurality of top blocks 27 can be installed on the main sleeve wheel 23 and the secondary sleeve wheels 25, so that when the pushing wheel 22 drives the main sleeve wheel 23 to approach the secondary sleeve wheels 25, the distance between the main sleeve wheel 23 and the secondary sleeve wheels 25 is reduced, and the connecting blocks 26 on the main sleeve wheel 23 and the secondary sleeve wheels 25 jointly push out each top block 27. In this way, when the axis of the steel coil is located on the rotating shaft 21, the pushing wheel 22 will drive each top block 27 to push outwards to support the coil.

[0036] It should be noted that a thread is provided on one end of the rotating shaft 21 close to the pushing wheel, and the pushing wheel 22 is screwed to the thread. When the rotating shaft 21 rotates, the pushing wheel 22 can drive the main sleeve wheel 23 to approach or move away from the secondary sleeve wheels 25. Further, a driving wheel 211 is provided on the end of the rotating shaft 21 far from the pushing wheel 22, and the driving wheel 211 is located on the side of the frame body 10 far from the pushing wheel 22. The driving wheel 211 is connected to the output end of the motor through a belt. When the motor drives the driving wheel 211 to rotate, the rotating shaft 21 drives the pushing wheel 22 to push the main sleeve wheel 23 to approach or move away from the secondary sleeve wheels 25, and further enables each top block 27 to support the coil.

[0037] As Figures 1 to 2 、 Figures 4 to 6As shown, in one embodiment, the clamping structure 30 includes a tensioning frame 31, a support member 32, a driving member 33, a plurality of bearing rods 34, and a plurality of telescopic members 35. The tensioning frame 31 is disposed on the frame body 10, the support member 32 is slidably disposed on the frame body 10, the tensioning frame 31 and the support member 32 are respectively located on both sides of the rotating structure 20, each telescopic member 35 is respectively disposed on the tensioning frame 31 and the support member 32, and each telescopic member 35 is circumferentially distributed on the tensioning frame 31 and the support member 32. Each bearing rod 34 is respectively disposed on the output end of each telescopic member 35, and each bearing rod 34 corresponds to each telescopic member 35 one by one, so that each telescopic member 35 drives each bearing rod 34 to clamp or loosen the coil. The driving member 33 is disposed on the frame body 10, and the output end of the driving member 33 is connected to the support member 32. The driving member 33 is used to drive the support member 32 to approach or move away from each bearing rod 34.

[0038] It should be noted that both the tensioning frame 31 and the support member 32 tend to be in a cross structure, and the tensioning frame 31 and the support member 32 are respectively located on both sides of the rotating structure 20. The tensioning frame 31 is disposed on the frame body 10, and the support member 32 is slidably disposed on the frame body 10, so that the support member 32 can slide relative to the frame body 10 to approach or move away from the rotating structure 20. Further, the telescopic member 35 is a telescopic rod structure. Each telescopic member 35 is respectively disposed on the tensioning frame 31 and the support member 32, and each telescopic member 35 is circumferentially distributed at the four corner positions of the tensioning frame 31 and the support member 32, and the output ends of each telescopic member 35 all face the edges of the tensioning frame 31 and the support member 32, so that the output ends of each telescopic member 35 can simultaneously extend outwards. Each bearing rod 34 is respectively disposed on the output end of each telescopic member 35, and each bearing rod 34 corresponds to each telescopic member 35 one by one. When each telescopic member 35 expands and contracts, each telescopic member 35 drives each bearing rod 34 to simultaneously approach or move away from the coil. Further, the driving member 33 is a hydraulic rod structure. There are two driving members 33, both of which are disposed on the frame body 10, and the two driving members 33 are respectively located on both sides of the frame body 10, and the output ends of the two driving members 33 are both connected to the support member 32, so that the two driving members 33 jointly drive the support member 32 to approach or move away from the rotating structure 20.

[0039] In this way, when the two driving members 33 drive the support member 32 to approach the rotating structure 20, the telescopic members 35 on the support member 32 are connected to the other ends of the bearing rods 34, so that the support member 32 and the tensioning frame 31 jointly enclose the rotating structure 20. By controlling the telescopic members 35 on the support member 32 and the tensioning frame 31 to contract the bearing rods 34, each bearing rod 34 jointly clamps the coil, so that each bearing rod 34 controls the tension of the coil, avoiding that when the tension is too large, the coil may be overstretched or even broken; and when the tension is too small, the coil may be loose and deviate, affecting the stability and accuracy of uncoiling, thereby reducing the product quality and production efficiency.

[0040] As Figures 1 to 2 、 Figures 4 to 6 shown, in one embodiment, at least one sliding hole 311 is formed in the tensioning frame 31, and one end of the bearing rod 34 passes through the sliding hole 311 and is connected to the output end of the telescopic member 35.

[0041] It should be noted that since the tensioning frame 31 has a cross-shaped structure, sliding holes 311 are formed at the four corner positions away from the axis center. Each telescopic member 35 is arranged on the side surface of the tensioning frame 31 away from the rotating structure 20, and the output end of each telescopic member 35 faces the sliding hole 311. In this way, each bearing rod 34 can pass through the sliding hole 311 and be connected to the output end of the telescopic member 35. Further, the sliding hole 311 has a long hole structure. When each bearing rod 34 at the four corner positions of the tensioning frame 31 passes through the sliding hole 311 and is connected to each telescopic member 35, each bearing rod 34 is located on the side of the tensioning frame 31 close to the rotating structure 20. It should be noted that the axis center of the tensioning frame 31 is consistent with the axis center of the rotating shaft 21. Each bearing rod 34 is located on the side of the tensioning frame 31 close to the rotating structure 20, so that each bearing rod 34 is located around the rotating structure 20, and the axis center of each bearing rod 34 is parallel to the axis center of the rotating shaft 21. In this way, when each telescopic member 35 pulls each bearing rod 34 to contract, each bearing rod 34 will jointly approach the rotating structure 20 to clamp the coiled material. On the contrary, when each telescopic member 35 pushes each bearing rod 34 to expand outwards, each bearing rod 34 will jointly move away from the rotating structure 20 to loosen the coiled material.

[0042] It should be noted that each bearing rod 34 has a bearing structure, so that when each bearing rod 34 clamps the coiled material, each bearing rod 34 can rotate along with the coiled material to prevent the coiled material from being unable to be unrolled due to the bearing rod 34 clamping the coiled material.

[0043] As Figures 1 to 2 、 Figures 4 to 6 shown, in one embodiment, the support member 32 includes a vertical frame 321. The vertical frame 321 is slidably arranged on the frame body 10, and the vertical frame 321 is connected to the output end of the driving member 33. At least one through hole 3211 is formed in the vertical frame 321, and the through hole 3211 is inserted with the end of the bearing rod 34 away from the tensioning frame 31.

[0044] It should be noted that since each bearing rod 34 is located on the side of the tensioning frame 31 facing the rotating structure 20, when the driving member 33 drives the vertical frame 321 to approach the rotating structure 20, each through hole 3211 and the sliding hole 311 are both long hole-shaped structures, and the lengths and directions of the through holes 3211 and the sliding holes 311 are the same, and the numbers of the through holes 3211 and the sliding holes 311 are in one-to-one correspondence. One end of each bearing rod 34 away from the tensioning frame 31 will be inserted into each through hole 3211 on the vertical frame 321, so that the vertical frame 321 and the tensioning frame 31 jointly enclose the rotating structure 20 through each bearing rod 34. Further, a circular ring portion 351 is provided on the output end of each telescopic member 35, and a circular hole 3511 is provided on each circular ring portion 351, and each circular hole 3511 is sleeved with both ends of each bearing rod 34. Further, one end of each bearing rod 34 passes through the sliding hole 311 on the tensioning frame 31 from one side of the rotating structure 20 and is inserted into the circular hole 3511 on each circular ring portion 351 on the other side of the tensioning frame 31 away from the rotating structure 20, and one end of each bearing rod 34 is screwed to the circular ring portion 351 by a screw, so that each bearing rod 34 is fixed on the output end of each telescopic member 35 on the tensioning frame 31. When the other end of each bearing rod 34 passes through the through hole 3211 on the vertical frame 321, it will be inserted into the circular ring of the telescopic member 35 on the vertical frame 321. Thus, when the driving member 33 drives the vertical frame 321 to approach each bearing rod 34, the telescopic members 35 on the vertical frame 321 and the tensioning frame 31 can jointly drive each bearing rod 34 between the vertical frame 321 and the tensioning frame 31 to clamp or loosen the coil material.

[0045] As Figures 1 to 2 , Figures 4 to 5 shown, in one embodiment, at least one positioning groove 3212 is further provided on the vertical frame 321, and the positioning groove 3212 communicates with the through hole 3211.

[0046] It should be noted that a plurality of positioning grooves 3212 are provided on the vertical frame 321. The positioning grooves 3212 are provided on one side surface close to the telescopic member 35, and are located at one end of the through hole 3211 away from the axis of the vertical frame 321, and the opening of the positioning groove 3212 faces the output end of the telescopic member 35, so that when the output ends of the telescopic members 35 on the vertical frame 321 extend, the output end of the telescopic member 35 can drive the circular ring portion 351 to be accommodated in the positioning groove 3212. Further, the positioning groove 3212 communicates with the through hole 3211, so that the circular hole 3511 on the output end of the telescopic member 35 communicates with the through hole 3211. When each bearing rod 34 is inserted into each through hole 3211, it is also inserted into each circular hole 3511. Thus, the telescopic members 35 on the vertical frame 321 are completed to be inserted with each bearing rod 34, and further, the telescopic members 35 on the vertical frame 321 can drive each bearing rod 34 to slide closer to or slide away from the coil material simultaneously with the telescopic members 35 on the tensioning frame 31.

[0047] As shown Figure 1 , Figure 4 , Figure 6 In an embodiment, the support member 32 further includes a base 322. The base 322 is slidably disposed on the vertical frame 321. The base 322 is used to support the coil material. The base 322 includes a bottom plate 3221 and shaft wheels 3222. The bottom plate 3221 slides on the vertical frame 321. The shaft wheels 3222 are rotatably disposed on the bottom plate 3221, and the shaft wheels 3222 are in contact with the frame body 10.

[0048] It should be noted that one side of the bottom plate 3221 close to the vertical frame 321 is slidably disposed on the vertical frame 321, so that the bottom plate 3221 can slide up and down relative to the vertical frame 321. Further, a plurality of shaft wheels 3222 are provided. Each shaft wheel 3222 is rotatably disposed on the bottom plate 3221, and each shaft wheel 3222 is located between the bottom plate 3221 and the frame body 10. When the driving member 33 drives the vertical frame 321 to slide close to or away from the rotating structure 20, the vertical frame 321 will push the bottom plate 3221 to slide close to or away from the rotating structure 20 through each shaft wheel 3222. Since the bottom plate 3221 is used to support the coil material, the driving member 33 pulls the vertical frame 321 to push the bottom plate 3221 to slide close to or away from the rotating structure 20, thereby enabling the vertical frame 321 to push the coil material close to the rotating structure 20. Further, an inner inclined groove is formed on the bottom plate 3221, and the inner inclined groove extends along the axial direction of the rotating shaft 21, so that when the coil material is placed on the bottom plate 3221, it is not easy to roll out of the bottom plate 3221 from both sides of the bottom plate 3221.

[0049] It should be noted that a lifting member is provided inside the bottom plate 3221, enabling the bottom plate 3221 to slide up and down relative to the vertical frame 321. Further, an axial center groove 3213 is formed on the vertical frame 321, and the axial center groove 3213 is sleeved with the end of the rotating shaft 21 away from the tensioning frame 31. When the driving member 33 drives the vertical frame 321 to slide close to the rotating structure 20, the vertical frame 321 will push the bottom plate 3221 close to the rotating structure 20. Further, when the coiled material is placed on the bottom plate 3221, the lifting member can drive the coiled material on the bottom plate 3221 to move up and down, so that the center of the coiled material is aligned with the axis of the rotating shaft 21. When the vertical frame 321 pushes the bottom plate 3221 close to the rotating structure 20, the end of the rotating shaft 21 away from the tensioning frame 31 passes through the center of the coiled material and is sleeved with the axial center groove 3213 on the vertical frame 321. In this way, each top block 27 is located inside the center of the coiled material. When the motor drives the pushing wheel 22 to push the main sleeve wheel 23 close to the slave sleeve wheel 25, so that each top block 27 expands outwards inside the center of the coiled material, the rotating shaft 21 can be attached to the center of the coiled material. At the same time, since one end of the rotating shaft 21 is rotatably arranged on the frame body 10 and the other end of the rotating shaft 21 is inserted into the vertical frame 321, and the coiled material is located on the rotating shaft 21, the vertical frame 321 and the frame body 10 jointly support the coiled material on the rotating shaft 21, and further enable the coiled material to rotate relative to the rotating shaft 21. In this way, the coiled material can slide horizontally into the rotating structure 20.

[0050] It should be noted that since each bearing rod 34 is located around the rotating structure 20, when each bearing rod 34 passes through the through hole 3211 and the round hole 3511, each bearing rod 34 jointly encloses the rotating structure 20. At this time, each telescopic member 35 can drive each bearing rod 34 to approach or move away from the coiled material to control the tension problem of the coiled material. At the same time, since each bearing rod 34 jointly encloses the coiled material, it can effectively prevent the coiled material from being instantaneously expanded due to excessive tension when the steel strip is unwound, which may cause personal safety problems for the staff. In this way, the safety accidents during the uncoiling of the steel coil can be reduced.

[0051] The above-described embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
