Banana Stem Fiber Scraping Device Hybrid Optimization Design Based on Response Surface Methodology

为了优化香蕉茎秆纤维提取机刮杂装置部件结构,提高纤维提取质量,以刮杂装置的刀辊速度、刀片间距、定刀弧长为影响因子,采用响应面优化设计方法,建立了影响因子与纤维提取率之间的数学模型,确定了较优的参数组合。试验表明:当香蕉纤维提取机刮杂装置影响因子的实际参数为刀辊转速1 200r/min、刀片间距1 1 0 mm、定刀弧长5 0 mm时,纤维提取率平均可达到9 2.6%,符合优化目标及生产要求。研究结果可为植物纤维提取装置的研发和应用提供理论依据和思路。

In order to optimize the banana stem fiber extraction scraping machine complex parts of the device structure to improve the fiber quality extraction, by scraping the impurity unit knife roller speed, blade spacing, knife arc length as influencing factors, using response surface optimization design method, established the mathematical model between influ- ence factors and fiber extraction rate to determine the optimum combination of parameters. Experiments show that when banana fibre extraction machine scraping miscellaneous devices influence factor of actual parameters for knife roller speed 1200R / min, the blade pitch 110 mm, fixed blade are length of 50 mm, fiber extraction rate average reaches 92.6% , in line with the optimization target and production requirements. The research results can provide theoretical basis and ideas for the development and application of plant fiber extraction device.
