香蕉茎秆纤维提取刀片的改进设计

Improved design of banana stalk fiber extraction blade

针对现有香蕉茎秆纤维提取机加工性能不理想的问题,通过借鉴手动刮胡刀设计原理,设计出双层渐近式刀片结构来优化其工作性能。对改进刀片与普通L型刀片进行了对比试验。结果表明:纤维提取率从14.50%提升到了16.03%左右,纤维含杂率从14.21%降到9.85%左右,而且在多片茎秆片叠加时加工效率更加稳定。

In view of the current unsatisfactory processing performance of existing banana stalk fiber extraction machine,by drawing on the design principle of manual razor,design a twolayer asymptotic blade structure to optimize its performance.A comparison test was made between the improved blade and the ordinary L-shaped blade.The results showed that the fiber extraction rate increased from 14.50% to 16.03%,and the fiber content decreased from 14.21% to 9.85%.The processing efficiency was more stable when multiple pieces of stalks were stacked.
