Description

Technical Field

[0001] The utility model relates to the technical field of steel belt conveying equipment, and particularly relates to a guide plate device for steel belt uncoiling. Background Art

[0002] During the steel belt rolling process, an uncoiler is required to unwind the steel belt to realize the conveyance of the steel belt to the rolling mill.

[0003] In the related prior art, the uncoiler includes an uncoiling mechanism. The uncoiling mechanism has a driving shaft, and a steel belt coil is sleeved on the driving shaft. The uncoiler further includes a guide plate mechanism located above the steel belt coil. The guide plate mechanism has a bracket and a conveyor belt arranged on the bracket. Magnets are arranged on the inner side of the conveyor belt. Therefore, driven by the driving shaft, the steel belt passes through the surface of the conveyor belt, and the magnets adsorb the steel belt, making the steel belt closely adhere to the surface of the conveyor belt, so that the steel belt is not easily dropped due to its own gravity during the conveying process, and the steel belt coil is prevented from unwinding too quickly.

[0004] However, during the long-term conveying process of the belt, it is easy to become loose, and the magnets are difficult to adsorb the steel belt, which affects the normal uncoiling of the steel belt coil. Summary of the Utility Model

[0026] The following describes a guide plate device for uncoiling a steel strip according to an embodiment of the present utility model with reference to the accompanying drawings.

[0027] Refer to Figure 1 , an embodiment of the present utility model aims to provide a guide plate device for uncoiling a steel strip.

[0028] A guide plate device for uncoiling a steel strip according to an embodiment of the present utility model includes a frame 100, a guiding mechanism, a suction mechanism and a pressing mechanism. The guiding mechanism includes a cantilever 110, a plurality of conveying rollers 120 arranged on the cantilever 110, and a driving assembly for driving the conveying rollers 120 to rotate. One end of the cantilever 110 is hinged to the frame 100, and the plurality of conveying rollers 120 are arranged along the conveying direction of the steel strip; the suction mechanism includes a permanent magnet 130 arranged on the cantilever 110, the permanent magnet 130 is located between two adjacent conveying rollers 120, and the permanent magnet 130 is used to attract the steel strip so that the surface of the steel strip is tightly attached to the outer surface of the radial direction of the conveying roller 120; the pressing mechanism includes a first cylinder 140, one end of the first cylinder 140 is hinged to the frame 100, and the other end of the first cylinder 140 is hinged to the cantilever 110.

[0029] It should be noted that an anti-slip sleeve can be sleeved on the outer surface of the radial direction of the conveying roller 120, and the anti-slip sleeve is in contact with the surface of the steel strip, which helps the conveying roller 120 to drive the steel strip to move.

[0030] In some embodiments of the present utility model, the cantilever 110 is provided with a guiding groove 150, the permanent magnet 130 is connected with a connecting block 160, and the guiding groove 150 accommodates the connecting block 160.

[0031] It should be noted that the guiding groove 150 extends downward, and the connecting block 160 can also be adjusted up and down in the extending direction of the guiding groove 150, so that the up and down position of the permanent magnet 130 can be changed, and the distance between the permanent magnet 130 and the steel strip can be adjusted according to steel strips of different thicknesses.

[0032] In some embodiments of the present utility model, the cantilever 110 is threadedly connected with an adjusting screw 170, and the end of the adjusting screw 170 is rotatably connected with the connecting block 160.

[0033] Therefore, the adjusting screw 170 can be rotated to move the connecting block 160 along the guiding groove 150, thereby changing the position of the permanent magnet 130, and the adjusting structure is simple.

[0034] In some embodiments of the present invention, a pressing wheel 180 is provided at one end of the cantilever 110 away from the first cylinder 140, and the radially outer surface of the pressing wheel 180 abuts against the radially outer surface of the steel strip coil.

[0035] By driving the cantilever 110 to approach the steel strip coil with the first cylinder 140, the pressing wheel 180 can contact the radially outer surface of the steel strip coil, avoiding the situation of loose coiling during the steel strip conveying process.

[0043] 1. By providing the cantilever 110 and the conveying roller 120, the present utility model can drive the cantilever 110 to swing by means of the first cylinder 140. When the cantilever 110 swings closer to the steel strip coil, during the process of feeding the steel strip coil, the steel strip slides across the surface of the conveying roller 120. Thus, the conveying roller 120 can guide the conveying direction of the steel strip, and the problem of the conveyor belt becoming loose during long-term use will not occur.

[0044] 2. By providing the permanent magnet 130, which is located between two adjacent conveying rollers 120, the permanent magnet 130 can adsorb the steel strip, making the steel strip closely adhere to the outer surface of the radial direction of the conveying roller 120. During the conveying process of the steel strip, it will not fall due to its own gravity, avoiding the problem of the steel strip coil unwinding too quickly, keeping the steel strip under a certain tension, ensuring the correct conveying direction of the steel strip, and improving the guiding reliability of the guide plate device.
