Pulping abrasive disc designing method

Abstract

The invention relates to the technical field of tobacco sheet production, in particular to a pulping abrasive disc designing method. The method comprises the main steps that in a pulping region and apre-pulping region, two concentric arcs with one tooth width interval are used for determining the position of one grinding tooth, on the basis, a plurality of grinding teeth are evenly arrayed aroundthe center of an annular fluted disc in the pulping region and the pre-pulping region, and one tooth groove with the width becoming larger gradually from interior to exterior is formed in the interval between every two adjacent grinding teeth; in a scattering region, one radius of the annular fluted disc rotates around the focal point on the outer edge of the scattering region to obtain a straight line, a column of grinding teeth are arranged along the straight line at the equal intervals of one tooth width, and on the basis, a plurality of columns of grinding teeth are evenly arranged aroundthe center of the annular fluted disc at the scattering region. Accordingly, a pulping abrasive disc is obtained, and the method has the advantages of being simple, feasible and accurate in design. The pulping fluted disc obtained through the designing method can reduce cutting and breaking of rod materials and increase the pulping yield.

Description

technical field [0001] The invention relates to the technical field of tobacco sheet production, in particular to a design method for beating and grinding sheets. Background technique [0002] The manufacture of paper-making tobacco sheets is an important technology in the tobacco industry at present. Adding an appropriate amount of tobacco sheets to cigarettes can save tobacco raw materials to the greatest extent and effectively reduce the cost of cigarettes; Physical properties and chemical components are adjusted and improved according to people's wishes or requirements, effectively reducing tar and other harmful substances in cigarettes, stabilizing the quality of cigarette products, and thus helping to improve the internal quality of cigarettes. An important technical measure. Compared with foreign products, there is still a big gap in the appearance, physical properties and internal quality of domestic paper-making tobacco sheets.

Compared with foreign products, there is still a big gap in the appearance, physical properties and internal quality of domestic paper-making tobacco sheets.

Compared with foreign countries, there is no obvious difference in the whole production process of papermaking reconstituted tobacco in my country. However, in terms of pulping, domestic papermaking reconstituted tobacco does not have a special beating and grinding sheet. Tobacco stems and tobacco powders are composed of tobacco stems and tobacco powders, and the differences between tobacco stems and tobacco powders are also large. Among them, the fibers of tobacco stems are elongated and ribbon-shaped, with long fibers, thin cell walls, large cell lumen diameters, and fiber surfaces that are easily divided into filaments; The end fibers are thick and short, the cell wall is thin, the cell lumen diameter is large, and the content of miscellaneous cells is high, which leads to the cutting and breaking of raw materials during the beating process, and the low pulp yield, which leads to poor quality stability of reconstituted tobacco leaves by papermaking method and product yield. The rate is low, which has an adverse effect on the copying process and the quality of the final product
