In recent years people make higher and higher demands on the home decoration with the improvement of the standard of living. Being its high intensity, good wear-resistant, clear and beautiful veins, and natural green environmental protection product which cater greatly to people’s psychology of returning to nature, bamboo materials have won peoples’ favor and have promising market prospect. In order to organize the great large-scale production, we must use the rational and high-efficient special processing equipment, But regarding bamboo as the production of material panel is the subject beginning to be studied until the 80′s . However, up to now the techniques that are necessary to bring about the industrialization of bamboo materials still rest on the unfurling half-bamboo by hot pressing and by venner lathe 2 kinds. In fact, the most valuable one, unfurling whole-bamboo without crack, hasn’t yet been adopted in domestic and foreign corporations because its degree of difficulty is relatively bigger.To get unfurled whole bamboo sheets without crack, removing the outer green from bamboo tubes is a most important technics, which has a great effect on the quality of the bamboo sheets. In this study great efforts are made to design a set of equipment for unfurling whole-bamboo without crack with low cost, convenient operation, high productive efficiency and suitability for industrialization. Its products, unfurled whole-bamboo sheets, thin shaved sheets, or thin face plywoods, will be 2500mms long, 250-320mms wide, and 5-6.5mms thick.Based on a great lot of references about the characteristic of the moso bamboo and the analysis of data taken from the raw materials, the technique of sand drum grinding is selected to remove the outer green from the moso bamboo rather than other techniques. The equipment we’ve designed has good compatibility and manipulability and its important components are optimized such as the fixture for fixing bamboo tubes and simple sand drum with small size.we designed a kind of special fixture that is much simpler, more dependable, and cheaper and its location is optimized too.In this study a new kind of equipment was developed to remove the outer green from bamboo tubes. Its products, especially the unfurling whole-bamboo, have good surface quality than those produced by the existing equipments. Its spread is of great significance.
