Description

Technical Field

[0001] The utility model relates to the technical field of paper rolling cylinders, in particular to a perforated paper rolling cylinder. Background Art

[0002] A reel is a device used in the paper industry to take up and transport the rolls of paper produced by a paper machine. This device usually consists of a large cylindrical shaft with support shafts and rubber-covered rollers on both sides. When the paper roll produced by the paper machine reaches a certain diameter, it needs to be removed from the paper machine and rolled up by a reel. The reel can absorb and fix the paper roll, then reel the paper by rotating the shaft, and finally compact and wrap it around the paper core to form the final paper roll. This device helps to automate and improve the efficiency of the paper production line, and is one of the indispensable equipment in the paper mill.

[0003] Most existing paper reel cylinders are non-perforated cylinders. When the paper reel cylinder is reeling paper, the paper is prone to wrinkles and looseness. The adsorption force of the paper reel cylinder on the paper is insufficient, which is not conducive to stable production.

However, the insufficient adsorption force of the paper reeling cylinder on the paper during operation will cause the paper to wrinkle and sag, which is not conducive to stable production.
