Description
Technical Field

Background
The material bearing plate of the material roll discharging machine is generally designed into a three-flap type or a four-flap type, and can be contracted inwards or expanded outwards along the radial direction. When the material roll is installed, the material bearing plate is in a contracted state. After the inner ring of the material roll is placed in the material bearing plate, the material bearing plate expands the inner ring of the material roll, so that the material roll is ensured not to slip during discharging. At present, the diameter of the arc surface of the material bearing plate is designed according to the diameter of the material coil inner ring, namely, the diameter of the arc surface of the material bearing plate is equal to the diameter of the material coil inner ring. As shown in fig. 1 and 2, when the material bearing plates shrink, the arc surfaces of the four material bearing plates are not on the same circle; when the material bearing plates are tensioned, the arc surfaces of the four material bearing plates are completely attached to the inner ring of the material roll. When the material bearing plates are expanded, a larger gap is formed between two adjacent material bearing plates, and the gap is required by a functional structure and is also indispensable. Because the clearance is not provided with the support of the material bearing plate, even if the two side surfaces of the material bearing plate are made into arc angles, the inner ring of the material rolling coil can be straightened and bent at the corresponding position of the clearance under the action of the tension force of the material bearing plate, and when serious, the inner ring of the material rolling coil can be bent outwards for a plurality of circles, so that a plate belt is scrapped or reworked and leveled.

For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.
As shown in fig. 3 and 4, the coil discharging machine of the present embodiment includes four material bearing plates 2, four material bearing plates 2 are symmetrically arranged along the circumferential direction of the coil inner ring 1, and a second gap 4 is provided between two adjacent material bearing plates 2. The material bearing plate 2 can expand outwards or shrink inwards relative to the axis, and when the material bearing plate 2 shrinks inwards, the material coil inner ring 1 is conveniently placed on the material bearing plate 2; when the material bearing plate 2 expands outwards, the material bearing plate 2 is used for tensioning the material roll inner ring 1, so that the material roll 5 is ensured not to slip during discharging. The radial surface of the material bearing plate 2 comprises an arc surface 21 and a first plane 23, and the first plane 23 is opposite to the arc surface 21. As shown in fig. 5, the arc surface 21 is connected to the first plane 23 through an arc angle 22. As shown in fig. 6, when the material bearing plate of the material roll discharging machine is used, the material roll 5 is disposed on the material bearing plate 2, the material roll inner ring 1 is the innermost layer structure of the material roll 5, and the material roll inner ring 1 is abutted against the middle of the surface of the circular arc surface 21.

Taking d generally according to the general design in the industry 1 ＝d 2 -(60mm～70mm)，d 2 ＝D 2 ++ (5 mm-10 mm). Diameter D of arc surface 21 of design material bearing plate 2 1 When d is to 1 Diameter D of circular arc surface 21 as material bearing plate 2 1 D is 1 ＝d 1 The method can be obtained through conversion: d (D) 2 -65mm＜D 1 ＜D 2 -50mm. When the material bearing plate 2 is contracted inwards to the innermost side, the four arc surfaces 21 can be contracted to the same regular circle, and the center lines of the arc surfaces 21 are coincident. When the material bearing plate 2 expands outwards to be abutted against the material coil inner ring 1, after the material coil inner ring 1 is tensioned, the true stressed part of the material bearing plate 2 is positioned in the middle of the arc surface 21, and the arc angle 22 of the material bearing plate 2 cannot be stressed.
