The invention discloses a pre-treating device for ramie degumming. The pre-treating device for the ramie degumming comprises a green scraping device and a rubbing device; the green scraping device andthe rubbing device are respectively arranged independently; the green scraping device is used for scraping down green peel of fresh ramie peel with ramie bone removed and conveying the ramie peel with the green peel scraped out; after the ramie peel with the green peel scraped is dried, performing rubbing treatment through the rubbing device; the ramie peel which is subjected to the rubbing treatment serves as the raw ramie for later degumming treatment. According to the pre-treating device for ramie degumming, the problems of time consumption and labour consumption caused by original artificial green scraping are effectively solved; the ramie peel which is subjected to the green scraping is rubbed through the rubbing device; on one hand, fibre bundles are dispersed, which is beneficial to the uniformity and high efficiency of later degumming; on the other hand, more gum is rubbed out by rubbing, the burden of later degumming is lightened; the primary processing of the ramie is greatly improved by combining the green scraping device and the rubbing device; time and labour are saved; the processes are simplified.
