One of its functions is to support the steel coil by tightening the inner hole of the steel coil; the other is to send the head of the steel strip into the leveler by rotating with the cooperation of the straightening machine. Therefore, the performance of the uncoiler is crucial to the entire production line. In many years of design practice, the uncoiler structure has been continuously optimized and improved, so that the performance of the uncoiler has been improved.

[0040] Example 1

[0041] Figure 1-3 The structure diagram of the first embodiment of the metal plate unwinding and feeding device of the present invention is shown. Figure 1-Figure 3 A metal plate uncoiling and feeding device in this embodiment includes a base 100 , a fixed base 200 , a sliding base 300 , an uncoiling and tightening assembly 400 , a driving assembly 500 and a supporting assembly 600 .

[0042] A base 110 is installed at the front end of the top of the base 100 .

[0043] The fixing seat 200 is installed on the top of the base 110 . A through hole 210 is opened on the side wall of the fixing seat 200 . A fixing plate 220 is installed on the top of the fixing seat 200 . A first motor 220 a is installed on the side wall of the fixing plate 220 .

[0044] The sliding seat 300 is slidably connected to the top of the base 100 , and a bottom plate 310 is installed at the front end of the bottom of the sliding seat 300 .

[0045] The unwinding tensioning assembly 400 includes a turntable 410 rotatably connected to the side wall of the fixing seat 200, a fixing column 420 installed on the rear side wall of the turntable 410, four tensioning plates 430 connected to the outer wall of the fixing column 420, and four extrusion plates 440 connected to the outer wall of the fixing column 420 and staggered with the tensioning plates 430. The side wall of the turntable 410 is installed with a shaft 410a, which passes through the through hole 210 and is connected to the first motor 220a. In the unfolded state, the four tensioning plates 430 and the four extrusion plates 440 are staggered to form a perfect circle, and the circle is consistent with the diameter of the inner hole of the metal sheet roll. In the initial state, the four tensioning plates 430 and the four extrusion plates 440 are staggered in inner and outer circles. For example, the extrusion plates 440 on the top and left are in the inner circle, the extrusion plates 440 on the bottom and right are in the outer circle, and the four tensioning plates 430 are in between. This arrangement order can facilitate the insertion into the inner hole of the metal sheet roll without affecting their respective unfolding.

[0046] The driving assembly 500 is installed at the front end of the accommodating chamber 210a and is connected to the four extrusion plates 440 respectively. When the first motor 220a drives the turntable 410 to rotate, the driving assembly 500 rotates with the turntable 410, and during the rotation process, drives the four extrusion plates 440 to expand and contract alternately in sequence in a manner that the extrusion plates 440 on the top and the left are one group, and the extrusion plates 440 on the bottom and the right are one group.

[0047] The support assembly 600 is installed on the top of the base plate 310, and the metal sheet coil is located on the top of the support assembly 600. The support assembly 600 is connected to the fixed column 420. When the fixed column 420 rotates, it drives the support assembly 600 to unfold upward, and provides auxiliary support when the metal sheet is unrolled. In the process of the turntable 410 driving the fixed column 420 to rotate and unroll the metal sheet coil, the fixed column 420 drives the support assembly 600 to slowly unfold upward according to the speed at which the diameter of the metal sheet coil shrinks.

At this time, the sliding seat 300 is moved forward close to the fixed seat 200, and the fixed column 420 extends into the inner hole of the metal plate coil. In the process of the sliding seat 300 moving forward, the four tensioning plates 430 are driven to unfold until the sliding seat 300 moves forward to the right position. The four tensioning plates 430 unfold and tighten the inner hole of the metal plate coil. At this time, the first motor 220a is started to drive the turntable 410 and the fixed column 420 to rotate, and then the first motor 220a is started to drive the turntable 410 and the fixed column 420 to rotate. The movable metal sheet coil rotates to unwind, and the driving assembly 500 is driven to rotate when the turntable 410 rotates. The driving assembly 500 drives the four extrusion plates 440 to unfold alternately to extrude the inner hole of the metal sheet coil, and can continuously change the force direction of the inner hole of the metal sheet coil during the unwinding process to prevent the inner hole of the metal sheet coil from deforming during the unwinding process. At the same time, when the fixed column 420 rotates, it drives the supporting assembly 600 to unfold slowly upward, and the bottom of the metal sheet coil is always auxiliary supported during the unwinding process of the metal sheet coil to relieve the pressure on the inner hole of the metal sheet coil.

[0053] The rear end of the fixed column 420 is provided with a connecting hole 420a, and four guide plates 420a-1 are installed inside the connecting hole 420a. The inner wall of the guide plate 420a-1 is rotatably connected to the third gear 420a-2. The outer wall of the fixed column 420 and the corresponding positions of the four guide plates 420a-1 are provided with four slots 420b. The second threaded rod 420b-1 is rotatably connected inside the slot 420b. Each second threaded rod 420b-1 is coaxially fixedly connected to the third gear 420a-2 corresponding to its position. The inner wall of the tensioning plate 430 is provided with an inserting plate 430a, and the inserting plate 430a extends into the opening Inside the groove 420b, the inner wall of the third threaded hole 430a-1 is provided with a third threaded hole 430a-1, the tensioning plate 430b-1 is rotated to extend into the third threaded hole 430a-1, the side wall of the sliding seat 300 is rotatably connected with a rotating rod 330, the rotating rod 330 is coaxial with the connecting hole 420a, the outer wall of the rotating rod 330 and the four guide plates 420a-1 are provided with four guide grooves 330a, the inner wall of the guide groove 330a is provided with an inner groove 330b, the inner wall of the inner groove 330b is installed with a first rack 330b-1, the side wall of the fixed column 420 is provided with four movable cavities 420c, and the movable A second positive and negative threaded rod 420c-1 is rotatably connected inside the cavity 420c, and a first movable block 420c-2 is also slidably connected inside the movable cavity 420c. A second threaded hole 420c-3 is provided on the side wall of the first movable block 420c-2. A first connecting plate 420c-4 is connected to the outer wall of the first movable block 420c-2. The other end of the first connecting plate 420c-4 is hinged to the inner wall of the extrusion plate 440. When the sliding seat 300 drives the metal plate roll to move toward the fixed seat 200, the fixed column 420 extends into the inner hole of the metal plate roll, and at the same time, the rotating rod 330 extends into the connecting hole 420a, guiding The guide plate 420a-1 extends into the guide groove 330a, and the third gear 420a-2 extends into the inner groove 330b and meshes with the first rack 330b-1. As the rotating rod 330 moves forward, the first rack 330b-1 drives the third gear 420a-2 to rotate, and the third gear 420a-2 drives the second threaded rod 420b-1 to rotate. When the second threaded rod 420b-1 rotates, the screw structure is used to push the plug plate 430a to drive the tensioning plate 430 to expand outward until the sliding seat 300 moves forward to its position. The four tensioning plates 430 are expanded to tighten and fix the inner hole of the metal plate roll. Figure 4It can be seen that two first movable blocks 420c-2 are relatively slidably arranged inside each movable cavity 420c. When the second positive and negative threaded rod 420c-1 inside the movable cavity 420c rotates, the screw structure is used to push the two first movable blocks 420c-2 inside the movable cavity 420c to approach or move away from each other. When the two first movable blocks 420c-2 approach each other, the two first movable blocks 420c-2 squeeze the first connecting plate 420c-4 to flip and push the corresponding extrusion plate 440 to expand outward. On the contrary, when the two first movable blocks 420c-2 move away from each other, the two first movable blocks 420c-2 drive the first connecting plate 420c-4 to flip and pull the extrusion plate 440 to shrink inward.
