Problems solved by technology

At present, the thickness of micro-corrugated cardboard on the market is greater than 0.4mm, so for those packaging boxes that require lower thickness, such as cigarette boxes, food boxes, etc., only cardboard boxes can still be used. Therefore, a tooth-shaped structure of corrugated rollers is developed. It has become a long-term and arduous task for corrugated roller manufacturers to produce micro-flute cardboard with a flute height lower than 0.4mm and a printing performance not lower than cardboard.

Abstract

The invention discloses an O-prism corrugated roller. A plurality of end-to-end corrugated teeth are formed at the periphery of the corrugated roller; the height (H) of each corrugated tooth is in the range of 0.3mm-0.4mm, the radius (r) of the point circle is in the range of 0.2mm-0.3mm, the radius (R) of the root circle is in the range of 0.5mm-0.7mm, and the pitch T is in the range of 1.15mm-1.35mm; in comparison with a current N-prism corrugated roller, the O-prism corrugated roller is characterized in that the bearing strengths of plane pressure and parallel pressure of a paperboard are increased by 30% under the same paper and pressure, a practical significance to print the paperboard and protect packaging products is present along with increasing of the bearing strengths, the paper consumption rate is reduced by 10-15% when the O-prism corrugated roller is compared with the N-prism corrugated roller, and thus the material cost is reduced and the benefit of a paper box manufacturing enterprise is improved.

Description

technical field [0001] The invention relates to a corrugated roller, in particular to an O-corrugated corrugated roller. Background technique [0002] Micro-corrugated is a new type of corrugated cardboard that has emerged abroad in recent years, such as F, N, and G types. Micro-corrugated cardboard has been regarded as the mainstream of the corrugated cardboard packaging material market in the future, because it has the dual effects of better physical properties and printing quality of corrugated cardboard and cardboard. Taking the European and American markets as an example, companies in the United States, Sweden, Germany and other countries have extended the traditional A, B, C, E and other corrugated types to F corrugated (corrugated height 0.75mm) with the in-depth research on the miniaturization of corrugated corrugated types. , G flute (0.50mm), N flute (flute height 0.46mm) total output value of corrugated cardboard accounts for about 8%. Micro-corrugated cardboard...
