Problems solved by technology

[0002] The slitting system, also known as the slitting machine, refers to a device for cutting paper. It mainly uses a cutter to cut the paper into a suitable width and then rolls it. However, when the paper is rolled During the process, due to the "resistance" of the paper by the cutter, it will be offset during the winding process, which will easily cause the misalignment of the winding (ie: the ends of the rolled paper roll are not neat), Defects that cause poor winding quality;
[0003] Not only that, when the paper is wound, due to the friction between the winding roller and the paper, a small amount of static electricity will be "imparted" on the surface of the paper, and the static electricity will absorb dust and other impurities in the air on the surface of the paper. The surface affects the forming quality of the paper. Although there are slitters that remove static electricity, there are still a small number of impurities that are adsorbed on the surface of the paper and are difficult to remove.

Abstract

The invention relates to a slitting system for papermaking and a papermaking slitting method thereof. The slitting system for papermaking comprises a supply roller used for installing paper rolls, a cutter used for cutting paper and a rewinding roller used for rewinding the paper and provided with at least two rewinding parts; the slitting system for papermaking is characterized by comprising at least two tidying parts and a driving device, wherein the tidying parts are movably arranged on the rewinding roller and are used for tidying the ends of the paper rolls on the rewinding parts, and thedriving device is used for driving the tidying parts to move. The slitting system for papermaking and the papermaking slitting method thereof have the beneficial effects that the tidying parts can bedriven by the driving device to move on the rewinding rollers, and one ends of the paper rolls on the rewinding parts are tidied, so that the winding effect of the paper rolls is better.
