Problems solved by technology
[0003] In the long-term production, it is found that there is a serious problem with this design: after the tail of the strip comes out of the reel, it will cause serious knocks on the guard plate, resulting in huge noise
When the strip tail 103E leaves the reel, it will hit heavily on the guard plate 301, resulting in a loud noise
Therefore, the disadvantage of the existing uncoiling device is that it cannot straighten the strip steel tail 103E, thereby causing the strip steel tail 103E to produce a strong impact on the guard plate 301, and then emit a huge noise

Embodiment Construction
[0028] The thick plate uncoiling device and method of the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments below.
[0029] image 3 The structure of the thick plate uncoiling device of the present invention in this embodiment is shown. Figure 4 for image 3 side view. Such as image 3 , Figure 4 As shown, one end of the deep bending roll frame 401 is hinged to the frame of the pinch roll 104 through a pin 403 at the first hinge point, and the deep bending roll frame 401 also has a chute opened along the horizontal direction. The deep bending roller 4 is arranged in the chute of the deep bending roller frame 401, and is connected with the second hydraulic cylinder 402 arranged on the deep bending roller frame 401, and the second hydraulic cylinder 402 drives the deep bending roller 4 to slide along the chute. The first hydraulic cylinder 404 is connected with the deep roll bending frame 401 to dr...

The invention discloses a thick plate decoiling device and a method employing the thick plate decoiling device. The thick plate decoiling device is arranged in front of a pinch roll along the moving direction of strip steel, and a PLC is adopted to control four driving elements in terms of driving a deep bending roll and a straight head knife so as to make the deep bending roll and the straight head knife cooperate to straighten the head and tail of a steel coil, thus avoiding severe impact of the strip steel tail on equipment. Therefore, huge noise caused by the impact can also be avoided, the equipment is protected and cannot be damaged due to the steel plate impact, and the service life of the equipment is prolonged.
Description
technical field [0001] The invention relates to a hot rolling finishing device and method, in particular to an uncoiling device and method. Background technique [0002] figure 1 It shows the structure of the existing hot-rolling finishing cross-cutting unit. Such as figure 1 As shown, after the steel coil 101 is fed to the reel 102, with the help of the deep bending roller 2 and the straight knife 3, the head of the strip 103 (the head of the steel coil 101) is introduced into the No. 1 pinch roller 104. Next, the steel strip 103 is sent to the rough leveler 106 for preliminary straightening after being centered by the No. 0 side guide plate 105 . After being preliminarily straightened, the steel strip 103 is cut at the head by the shears 107, and then the iron oxide scale remaining on the surface of the steel strip 103 is cleaned by the brush roller 108. Guided by the No. 1 side guide plate 109 and the No. 2 pinch roller 110, the strip steel 103 enters the disc shears ...
