Description

Technical Field

[0001] The utility model relates to the field of rolling devices, in particular to a rolling device for flame-retardant sheets. Background Art

[0002] A flame-retardant sheet is a sheet-shaped product made of a material with flame-retardant properties through special treatment, mainly used for fire prevention and preventing the spread of fire. Flame-retardant sheets are usually made of various plastics (such as polyethylene, polypropylene, polyvinyl chloride, etc.) or rubber substrates, and flame retardants are added during the manufacturing process. These flame retardants can inhibit or delay the combustion process during a fire and reduce the spread of flames;

[0003] In the prior art, during the production of flame-retardant sheets, it is necessary to roll them to eliminate air bubbles, voids and other defects inside the material, increase the density of the sheets, thereby improving their mechanical properties such as strength and hardness, making them more suitable for applications in fields that require high strength and durability; however, in traditional rolling devices, generally, the flame-retardant sheets are rolled in the advancing direction. At this time, the pressure exerted by the rolling rollers on the flame-retardant sheets will cause the material to extend in the advancing direction, while the flow in the transverse direction is relatively small. This uneven flow will result in uneven thickness distribution of the flame-retardant sheets in the transverse direction, especially for wide-width sheets, thus affecting the performance and appearance of the flame-retardant sheets and reducing the yield of the products.

[0004] Therefore, there are defects in the prior art and improvement is needed. Summary of the Utility Model
