Corrugated roll adopting corrugated structure, capable of reducing gram weight of paper without reducing paperboard intensity

Abstract

The invention discloses a corrugated roll adopting a corrugated structure capable of reducing gram weight of paper without reducing paperboard intensity, and relates to corrugated rolls for processingcorrugated boards. The corrugated roll adopting the corrugated structure, capable of reducing gram weight of the paper without reducing paperboard intensity is characterized in that a second corrugated top arc r2 is introduced in the corrugated top arc of the corrugated roll adopting the corrugated structure. Through the adoption of the corrugated roll adopting the corrugated structure capable ofreducing gram weight of paper, without reducing the paperboard intensity disclosed by the invention, the service life of the corrugated roll can be greatly prolonged; stressing state and impacting state of corrugated core paper during meshing shaping are improved; the corrugated core paper is in wider, continuous and gentle contact with the corrugated top arc, so that damage during shaping is reduced; the corrugated contact state is improved, the tension factor in a meshing region is reduced, and damage to the corrugated core paper in the meshing region caused by continuously-increased tension is reduced; the corrugated roll is well positioned, and deviation and vibration are reduced; the corrugated waist length of the corrugated paper is increased, and the paperboards are firm; the paperutilization rate of the corrugated roll is reduced; under the premise that the glue applying capacity is constant, the bonding region is wider, and adhering is more effective; the state of impressionof the paperboards can be obviously improved; and for low-gram weight corrugated core paper, the beneficial effects of the corrugated roll adopting a corrugated structure are better.

Description

technical field [0001] The present invention relates to a corrugated roller for processing corrugated cardboard, and further relates to the corrugated structure of the corrugated roller, in particular to the structure of the corrugated top arc aa of the fluted structure of the corrugated roller; Rolls and finished corrugated rolls from the factory; the corrugated rolls with a corrugated structure are mainly defined by the detection and analysis results of the profiler, but are not limited to a single detection and analysis method of the profiler. Background technique [0002] 1. Corrugated cartons are the most widely used green and environmentally friendly packaging products. The corrugated box is made of corrugated cardboard, and the corrugated cardboard is manufactured by the corrugated cardboard production line. The core of the corrugated cardboard production line is the corrugating machine, and the core component of the corrugating machine is the corrugating roller. The...

Problems solved by technology

[0014] The purpose of the present invention is to provide a corrugated roll with a corrugated structure that reduces the grammage of paper but does not reduce the strength of the cardboard. The structure of the corrugated top arc aa is used to solve the problem of the traditional corrugated structure corrugated roller simply increasing or decreasing the radius of the corrugated top arc r to optimize the design of the corrugated roller. At the same time, it must suffer from its disadvantages" technical problem
