高低瓦楞辊齿形尺寸参数研究

Tooth Size Parameters of High and Low Corrugated Roller

目的研究一种"高低瓦楞辊"组的齿形及具体尺寸,为制造高低瓦楞辊组提供设计参数,从而生产出高低瓦楞夹芯。方法在分析传统"等高瓦楞辊"齿形及有关标准尺寸参数基础上,预先确定基本尺寸参数值,并采用AutoCAD设计制图得出瓦楞辊齿形其他尺寸参数,然后模拟瓦楞辊滚压纸板过程,并测量纸板在瓦楞辊齿上的包角。按照纸板成形过程中张力的必要条件验算纸板成形的可行性,反复设计验算。结果得出了高低瓦楞辊齿形尺寸参数值。结论这种齿形尺寸参数的高低瓦楞辊能使纸板在瓦楞辊齿上的包角值为340°和332°,达到纸板成形过程张力要求,可作为高低瓦楞辊齿形尺寸参数。

Objective To provide a new tooth profile and size of ＂ High and Low corrugated roller＂, in order to provide a reference for corrugated roller group and corrugated sandwich manufacturing. Methods It was based on the analysis of some traditional ＂equal-high corrugated roller tooth＂ profiles and relative standard size parameters. Parameter values of basic sizes were determined firstly, and the other size parameters of corrugated roller tooth were then obtained by AutoCAD software. After that, the rolling process of corrugated roller on the cardboard was simulated and the wrap angle of the cardboard on the corrugated roller was measured. The feasibility of cardboard forming was verified according to necessary condition of tension in cardboard forming process. Results The high and low corrugated roller tooth size parameter values were obtained. Conclusion Using the ＂ High and Low corrugated roller＂ with this tooth size parameter values, the cardboard could form a wrap angle of 340° or 332° on the corrugated tooth roller, which meets the tension requirement of the paperboard forming process and can be used as the size parameter for ＂High and Low corrugated roller＂.
