Description

Technical Field

[0001] The utility model relates to the field of paper production, and more specifically, it relates to a paper feeding and guiding mechanism for a high-speed paper slitter. Background Art

[0002] Paper is very common in people's lives. Paper greatly facilitates people's production and life. During the production of different papers, it is often necessary to slit the paper. Therefore, a high-speed paper slitter is needed to slit the paper. When feeding the paper into the slitter, a paper feeding and guiding mechanism is required to feed the paper into the slitter. The existing paper feeding and guiding mechanism often uses smooth guide rollers to convey the paper. During the conveyance of the paper, due to the movement of the paper and the lack of a limiting structure on the guide rollers, the paper will slide on the guide rollers, easily causing the paper to slip off the guide rollers, affecting the smooth conveyance of the paper, and being inconvenient for high-precision cutting of the paper. At the same time, after the paper roll is conveyed, the existing paper feeding and guiding structure needs to replace the paper roll. When replacing, it is necessary to disassemble and reinstall the paper roll, which takes a long time. Therefore, it affects the slitting efficiency of the paper and the production of the paper.
