📝 Foreword / 前言 ai_extracted
This standard is a revision based on the original standard GB 12070-1989 (Medium and Low Speed Corrugated Board Production Line) (which was converted into industry standard QB/T 3920-1999 by Document No. [1999] 112 of the former State Bureau of Light Industry, with the content unchanged). It incorporates the current situation of corrugated board production line manufacturing in China and references relevant standards of similar international products. The main revisions are as follows: — Added "Foreword" and "Installation and Acceptance Rules"; — Added specifications for high-speed type corrugating lines in Table 1; — In Table 2, the original number of flutes for E-flute type, 96±4, was changed to flute height 1.1 mm-1.5 mm, number of flutes 92±2; flute height 1.5 mm-1.8 mm, number of flutes 88±2; — In Table 3, the precision of corrugating tooth profiles for medium and low speeds was revised, and precision requirements for corrugating tooth profiles of high-speed type corrugating lines were added; — Added tests for electrical equipment in the test methods. This standard replaces QB/T 3920-1999 from the date of implementation. This standard was proposed by the Industry Management Department of the former State Bureau of Light Industry. This standard is under the jurisdiction of the National Technical Committee for Standardization of Light Industry Machinery. Drafting organizations of this standard: China Aerospace Science and Technology Corporation, Packaging Machinery Research Institute of Capital Aerospace Machinery Company. Main drafters of this standard: Lu Ruixian, Yan Xiaolin. People's Republic of China Light Industry Industry Standard QB/T 2498-2000 Corrugated Board Production Line Replaces QB/T 3920-1999
本标准是在原标准GB 12070-1989(中、低速瓦楞纸板生产线) (该标准由国轻行〔1999)112号文 转化为行业标准QB/T 3920-1999，内容不变)的基础上进行的修订，结合了目前我国制造瓦楞纸板生 产线的情况，并比照国际同类产品相关标准。其主要修改内容如下: — 增加了“前言’ ，和“安装验收规则”; — 表1中增加了高速型瓦线的规格; — 表2中原E楞型的楞数96士4，改为楞高1.1 mm-1.5 mm,楞数92士2;楞高1. 5 mm- 1. 8 mm,楞数88士2; — 表3中对中、低速瓦楞齿型精度进行了修订，并增加了高速型瓦线瓦楞齿型精度要求; — 试验方法中增加了电气设备的试验。 本标准自实施之日起，同时代替QB/T 3920-1999, 本标准由国家轻工业局行业管理司提出。 本标准由全国轻工业机械标准化技术委员会归口。 本标准起草单位:中国航天科技集团公司、首都航天机械公司包装机械研究所。 本标准主要起草人:卢瑞现、严晓林。 中华人民共和国轻工行业标准 QB/T 2498-2000 瓦楞纸板生产线 代替QB/T 3920-1999
