Device for eliminating internal stress of paper web

Abstract

The invention relates to the technical field of paper web production, and in particular relates to a device for eliminating internal stress of a paper web, the device comprises a box body, and furthercomprises an ionizer, an input limiting roller, a preheating piece, a reverse bending roller, an output limiting roller and a driving component which are sequentially arranged in the box body along the conveying direction, wherein the reverse bending roller is positioned below the preheating piece and the output limiting roller; the driving component comprises a first rotating shaft rotationallyconnected to the box body and a driving source for driving the first rotating shaft to rotate; a single sheet of paper in an external paper web sequentially passes through the ionizer, the input limiting roller, the preheating piece, the reverse bending roller, the output limiting roller and the first rotating shaft under the drive of the driving source to finish eliminating the internal stress ofthe paper web and then enters a next working procedure; by arranging the ionizer, the preheating piece and the reverse bending roller in the box body, static charge, bending stress and moisture in the paper web are eliminated in the process of unfolding the paper web, the performance of the paper web is restored, and the flatness of the paper web in the subsequent transverse cutting working procedure is ensured.

Description

technical field [0001] The invention relates to the technical field of paper web production, in particular to a device for eliminating the internal stress of the paper web. Background technique [0002] Rolled paper is the ultimate product of the paper mill. The paper roll is rolled into a cylindrical shape under the action of the upper and lower pressure rollers of the high-speed rewinder. During the rolling process, the paper web is continuously curled around the paper core, and the inside of the paper web Continuous bending deformation, stress accumulation, and mutual friction between the paper webs cause a considerable concentration of electrostatic charges to accumulate on the surface. The electrostatic charge and the adhesiveness of the bending stress work together to form a closed body in the web, and the electrostatic charge And the bending stress exists inside the paper roll for a long time, and the paper webs are more tightly attached to each other. When the paper ...
