Because the two fixed conveying arms 8 are parallel to each other and form an included angle of 10-25 degrees with the horizontal direction, a discharging cylinder 15 is arranged below each group of movable winding arms 9, a piston rod of the discharging cylinder 15 is hinged with the movable winding arms 9, and a core barrel 10 is arranged between the fixed conveying arm 8 and the movable rolling arm 9, when rolling sheets, a piston rod of the discharging cylinder 15 is lifted upwards, so that the movable rolling arm 9 and the fixed conveying arm 8 form an included angle of about 120 degrees by taking the first shaft 8-1 as an intersection point, thereby leading the core barrel 10 to be positioned in an included angle formed by the movable rolling arm 9 and the fixed conveying arm 8, leading the moving rolling arm 9 and the fixed conveying arm 8 to form a V-shaped state, providing a guiding function for the trend of the sheet material, in the initial stage of winding the sheet, the diameter of the core cylinder 10 is manually pressed to wind the sheet for a certain length, and the core cylinder 10 presses the sheet to prevent the sheet from scattering. And then the pressing cylinder 11 in the pressing mechanism is manually lowered, so that the two pressing rollers 13 are pressed on the sheet, and the rolled sheet is prevented from loosening. The fixed conveying arm 8, the movable winding arm 9 and the two pressing rollers 13 form four necessary supporting points for winding sheets, in the winding process, friction force is generated between the sheets and the friction belt on the fixed conveying arm 8 and the friction belt on the movable winding arm 9, the driving roller is driven to rotate by the friction force, so that the core barrel 10 is driven to rotate by the friction belts and the driving roller, the sheets are continuously wound on the core barrel 10, once deviations appear at two ends of the sheets in the winding process, the height of the movable winding arm 9 can be adjusted through the discharging cylinder 15, and two ends of the wound sheets are flat. Along with the increase of the winding diameter of the winding on the core barrel 10, the pressure of the pressing cylinder 11 can be adjusted, the lifting seat 14 is guided by the guide column 12 under the driving of the pressing cylinder 11, the two pressing rollers 13 are upwards lifted through the piston rod, a space is reserved for the core barrel 10 to rotate and continue to wind the sheets, and the wound sheets are not loosened. And cutting off the sheet until the winding length of the sheet reaches the requirement, finishing the winding, and then manually lowering the discharging cylinder 15 to enable the wound sheet to fall into the discharging device 20 along with the core barrel 10, thereby finishing the winding.
The distance between the vertical frames 7-1 at two sides of the rack 7 is more than 5 meters, so the winding device 2 can accommodate the ultra-wide sheets with the width of more than 5 meters, and even the distance between the vertical frames 7-1 can be made to be more than 10 meters according to the width of the sheets, thereby meeting the winding requirements of various ultra-wide sheets. Moreover, because the thickness and the hardness of the sheet are different, and the required winding diameter is correspondingly different, the core cylinders 10 with different diameters can be replaced according to the thickness of the sheet, so that the winding of the sheet with various thicknesses and hardnesses is completed, even the winding of the sheet with the thickness of more than 3mm is solved, and the sheet fracture caused by the over-small winding diameter is avoided. In addition, the invention firstly completes the rolling of a section of length by manual assistance at the beginning of the rolling, so that the edge of the sheet can not crack due to overlarge shearing force at the beginning of the rolling, and the good quality of the sheet is ensured. Therefore, the invention can complete the rolling of the ultra-wide sheet with large width, large roll diameter and larger thickness.
