Description

Technical Field

[0001] The utility model relates to the technical field of papermaking, and more specifically, to a novel roll paper shaft. Background Art

[0002] When producing roll paper, it is usually centered on a paper shaft, and several layers of paper towels are wound around the periphery of the paper shaft. During the use of the roll paper, it is often necessary to pull out the paper shaft so as to gradually pull out the paper towels from the inside of the wound paper towels for use.

[0003] The roll surface of the roll paper shaft of traditional high-speed toilet paper machines is mostly made of a steel roller wrapped with rubber. After the base paper is wound on the paper machine, the base paper can be transferred to a rewinder and slitter for processing into the specifications required by customers. If some customers do not need slitting and need the base paper from the paper machine, or various specifications of the base paper products need to be stocked, then a large number of roll paper shafts are required for turnover, which brings a certain economic burden. Therefore, a roll paper shaft that is inexpensive, can be turned over, and can be reused is needed. Summary of the Utility Model
