苎麻自动剥麻机设计与试验

Design and Test of Ramie Automatic Stripping Machine

针对现有苎麻剥麻机操作强度高、工作安全性差、作业工效低,特别是多滚筒直喂剥麻机存在苎麻梢部和基部末端麻骨剥离不干净、剥麻滚筒易缠绕等问题,提出了集压、刮、打、夹和梳等多道剥麻工序于一体的苎麻自动剥麻机技术方案,并对苎麻自动剥麻机进行了设计与试验。该机不需人工反拉剥麻,可实现连续剥麻,解决了苎麻尾端剥麻不干净、剥麻滚筒缠绕、杂质含量高等问题。整机原麻生产率58 kg h,鲜茎出麻率6.3%,原麻含杂率1.32%,达到二等苎麻纤维标准,可加工的苎麻茎秆长度≥800 mm(去叶)。

In view of high operating strength,poor work safety,and low work efficiency of existing ramie stripping machine,especially ramie tip and base end of multi-roller direct feed stripping machine is not clean and stripping drum is easy to twist,a technical scheme for an automatic ramie stripping machine integrating multiple stripping processes such as pressing,scraping,beating,clamping and combing,was proposed,and a design test was carried out on ramie automatic stripping machine.The machine did not need manual reverse pulling and stripping,and could realize continuous stripping which solved problems of unclean stripping at the end of ramie,entanglement of stripping drum,and high impurity content.The raw ramie productivity of whole machine was 58 kg h,fiber percentage of fresh ramie stem was 6.3%,and percentage of ramie impurities content was 1.32%,reaching second-class ramie fiber standard,and length of processable ramie stem was greater than or equal to 800 mm(remove leaves).
