Description

Technical Field

[0001] The present invention relates to the field of steel coil uncoiling, and in particular to an uncoiling machine with an automatic leveling mechanism. Background Art

[0002] The uncoiler is a special equipment for leveling metal sheets, and its shaft head is responsible for stretching out the rolled steel coil, loosening the originally tightly rolled steel coil, making it easier for the steel strip to be subsequently unrolled and leveled.

[0003] After the steel coil is wound, it has a certain potential energy. Therefore, the action of unwinding is generally relatively slow. This is to avoid the unwinding speed being too fast, which will cause the coil to loosen and cause unnecessary trouble. In addition, there are generally certain requirements for the tension of the steel coil when unwinding, especially for relatively wide steel coils. If the tension on the left and right sides is inconsistent during unwinding, the unwinding work will be very troublesome. Generally, the manufacturer will return the steel coil to the supplier in this case, but the supplier also needs to re-unwind and rewind during the processing process to ensure subsequent use. Even in such cases, the uncoiler still needs to be used for unwinding operation. At the same time, during the unwinding process, the steel strip follows the guide roller for transportation, and the direction of the steel strip may deflect, which affects the normal unwinding.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0034] Through the above-mentioned scheme of the present invention, the loading component 2 provided in the present invention can be moved and adjusted on the bottom frame 1, which can facilitate the delivery of the steel coil to the position of the unwinding component 3, and the mutual cooperation between the lifting cylinder 12 and the loading cylinder 10 provided on the loading component 2 can facilitate the insertion of the steel coil drum into the outside of the unwinding shaft 29. The special design of the loading plate 13 also facilitates the unloading of subsequent drums. The loading component 2 as a whole can also be fine-tuned on the bottom frame 1, which can better cooperate with the loading component 2 to load the steel coil, and at the same time, it can also make certain adjustments to the unwinding direction of the steel coil during subsequent unwinding. The support plate 46 provided on the outside of the unwinding shaft 29 can also be adjusted to achieve the tightening of drums with different inner diameters.

A mounting bracket 68 is fixedly mounted on the outside of the end of the adjustment shaft 66 close to the support plate 46. A pressure roller 69 is rotatably mounted on the end of the mounting bracket 68 away from the adjustment shaft 66. The adjustment shaft 66 can rotate, thereby causing the pressure roller 69 to move toward the support plate 46, thereby pressing the outside of the steel coil, ensuring that the steel coil will not unwind during the uncoiling process, and achieving stable uncoiling.

[0036] A third hinged seat 62 is fixedly mounted at the top center of the first extension seat 61. A pressing cylinder 63 is mounted on the third hinged seat 62. A swing arm 67 is also fixedly mounted on the adjustment shaft 66. The output shaft end of the pressing cylinder 63 is hingedly connected to the end of the swing arm 67. When the pressing cylinder 63 is activated, it drives the swing arm 67 to swing, which in turn drives the adjustment shaft 66 to rotate, thereby adjusting the position of the pressure roller 69.

[0037] A reinforcing rod 70 is also fixedly installed inside the mounting frame 68 , and the reinforcing rod 70 can ensure the stability of the assembly of the pressure roller 69 .

[0038] Through the above-mentioned scheme of the present invention, the pressure roller 69 provided in the present invention can achieve pressure holding on the outside of the steel coil, ensuring stable uncoiling of the steel coil during the uncoiling process, and no loose coiling phenomenon will occur. The position of the pressure roller 69 can be adjusted by the clamping cylinder 63, changing with the change of the size of the steel coil during the uncoiling process, and always achieving pressure on the outside of the steel coil.

[0039] Example 3: Please refer to Figure 16-23 For Example 1 and Example 2, in order to enable the leveling component 5 to maintain a stable tension on the steel strip output during the unwinding process of the steel coil, in this embodiment, the leveling component 5 includes a second extension seat 71 fixedly mounted on the side of the support seat 24, the second extension seat 71 is arranged away from the first extension seat 61, and an extension arm 72 is fixedly mounted on the top of the second extension seat 71, and the extension arm 72 is arranged in the direction of the feeding component 2, and a support frame 73 is fixedly mounted on the top of the extension arm 72 away from the second extension seat 71, and a balancing frame 74 is mounted on the top of the support frame 73, and a leveling frame 75 is fixedly mounted on the top of the balancing frame 74, and a horizontal strip 76 is rotatably mounted on the top of the leveling frame 75, and a correction roller 77 arranged along its length direction is rotatably mounted on the horizontal strip 76. The assembly between the balance frame 74 and the support frame 73 can realize automatic balance adjustment. If uneven tension occurs when the steel coil is unwound, the balance frame 74 will automatically adjust to make the correction roller 77 automatically tilt, thereby ensuring that the overall tension of the steel strip is uniform when the steel coil is output during unwinding, and ensuring stability when the steel strip is subsequently received.

[0040] An extension frame 78 is symmetrically installed along the center of one side wall of the leveling frame 75 away from the winding assembly 3, and a detector 79 is installed on the extension frame 78. The two detectors 79 are arranged relative to each other to detect the position of the steel strip. When the center is offset, the centering can be corrected by adjusting the position of the correction roller 77. The top center of the leveling frame 75 is rotatably installed with a vertical shaft 80, and the bottom center of the horizontal strip 76 is fixedly installed on the vertical shaft 80. A fourth articulated seat 82 is fixedly installed on the outer wall of the leveling frame 75, and a correction cylinder 83 is installed on the fourth articulated seat 82. A traction frame 84 is fixedly installed on the middle part of the outer side of the horizontal strip 76, and the output shaft end of the correction cylinder 83 is connected to the traction frame 84. When the detector 79 detects that the unwinding steel strip is deflected, the correction cylinder 83 can be controlled to start. The correction cylinder 83 will pull or push the traction frame 84 to move, and the traction frame 84 will drive the horizontal strip 76 to rotate around the vertical axis 80. At this time, the correction roller 77 can adjust the unwinding direction of the steel strip to ensure that it is always in the center position.

[0041] A stabilizing plate 81 is symmetrically mounted on the top of the leveling frame 75, and a stabilizing wheel 85 is symmetrically mounted on the bottom of the horizontal strip 76. The bottom of the stabilizing wheel 85 is tightly against the top of the stabilizing plate 81. The mutual assembly of the stabilizing wheel 85 and the stabilizing plate 81 can ensure the stability of the correcting roller 77.

[0042] A balancing shaft 86 is symmetrically mounted along the center at the bottom of the balancing frame 74, and balancing wheels 87 are rotatably mounted on both ends of the balancing shaft 86. The support frame 73 is integrally formed by two oppositely arranged arc-shaped plates, and arc-shaped grooves 89 are formed on the opposite side walls of the two arc-shaped plates. The balancing wheels 87 are rotatably mounted in the arc-shaped grooves 89. When the steel belt passes over the top of the correcting roller 77, if the tension on both sides of the steel belt is inconsistent, there will be a pressure difference between the two sides of the correcting roller 77 that are in contact with the steel belt. At this time, the side receiving the greater pressure from the steel belt will apply force to the leveling frame 75 through the horizontal strip 76. The leveling frame 75 then acts on the balancing shaft 86 through the balancing frame 74, so that the balancing wheels 87 automatically rotate in the arc-shaped grooves 89, so that the entire steel belt can be in stable contact with the correcting roller 77, ensuring stable conveying of the steel belt by the correcting roller 77.

[0043] The arcuate slot 89 is further provided with an arcuate rod 90 extending along its length. A through hole 88 is formed at the end of the balancing shaft 86, through which the arcuate rod 90 is inserted. A tensioning spring 91 is symmetrically sleeved on the exterior of the arcuate rod 90 along the center. The tensioning spring 91 is positioned between the balancing shaft 86 and the adjacent end of the arcuate slot 89. A locking bolt 92 is also mounted on the end of the arcuate rod 90. The two tensioning springs 91 on the same arcuate rod 90 act on the ends of the two balancing shafts 86, respectively, to ensure that the balancing frame 74 does not easily tilt.

[0044] Through the above-mentioned scheme of the present invention, the balance frame 74 provided in the present invention can automatically roll and adjust in the arc groove 89 in the support frame 73 through the balance wheel 87 at the end of its bottom balance shaft 86, so that the correction roller 77 can automatically adapt when it is subjected to pressure from the steel belt, ensuring that even if the tension of the steel belt is uneven, it can always fit with the correction roller 77 to achieve stable unwinding and transportation, and the correction roller 77 can also realize correction adjustment of the steel belt through the correction cylinder 83, ensuring that the steel belt is always in a centered unwinding state when the steel coil is unwinding, thereby ensuring further stability of the unwinding.

[0045] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0046] The loading assembly 2 provided in the present invention can be moved and adjusted on the bottom frame 1, which can facilitate the delivery of the steel coil to the position of the unwinding assembly 3, and the mutual cooperation between the lifting cylinder 12 and the loading cylinder 10 provided on the loading assembly 2 can facilitate the insertion of the steel coil drum into the outside of the unwinding shaft 29. The special design of the loading plate 13 also facilitates the unloading of subsequent drums. The loading assembly 2 as a whole can also be fine-tuned on the bottom frame 1, which can better cooperate with the loading assembly 2 to load the steel coil, and at the same time, it can also make certain adjustments to the unwinding direction of the steel coil during subsequent unwinding. The support plate 46 provided on the outside of the unwinding shaft 29 can also be adjusted to achieve the tightening of drums with different inner diameters. At the same time, the adaptive pressing assembly 4 and leveling assembly 5 can further ensure the stability of the steel coil during unwinding.

[0047] The pressure roller 69 provided in the present invention can achieve pressure holding on the outside of the steel coil, ensuring stable unwinding of the steel coil during the unwinding process without loose coiling. The position of the pressure roller 69 can be adjusted by the clamping cylinder 63, changing with the change in size of the steel coil during the unwinding process, and always achieving pressure on the outside of the steel coil.

[0048] The balancing frame 74 provided in the present invention can automatically roll and adjust in the arc groove 89 in the support frame 73 through the balancing wheel 87 at the end of its bottom balancing shaft 86, so that the correcting roller 77 can automatically adapt when it is subjected to pressure from the steel belt, ensuring that even if the tension of the steel belt is uneven, it can always fit with the correcting roller 77 to achieve stable unwinding and transportation. The correcting roller 77 can also realize the correction adjustment of the steel belt through the correcting cylinder 83, ensuring that the steel belt is always in a centered unwinding state when the steel coil is unwinding, thereby ensuring further stability of the unwinding.
