摘要： The invention relates to the technical field of machining of bamboo products, in particular to a bamboo straw machining method, comprising: connecting two or more bamboo pieces to form a bamboo strip, continuously winding the bamboo strip according to a preset helical angle to form a cylinder, and cutting the cylinder according to a preset interval to form straws. Compared with traditional bamboo straw machining methods, the method provided by the invention has the following advantages: bamboo pieces are continuously connected to obtain a bamboo strip to make a preparation for continuous production, then the continuous bamboo strip is continuously wound to obtain a cylinder which is good in mechanical property, stable in structure and uniform in appearance, and finally, the cylinder is cut at equal intervals to continuously produce bamboo straws that are highly consistent in specification and performance; and the working efficiency is improved by over 20% on the whole, and labor and equipment costs are greatly reduced.

摘要： The present invention discloses a bamboo outer skin-retaining bamboo veneer and a preparation process thereof, belonging to the technical field of bamboo processing. The preparation process includes the following steps: segmenting bamboo and cutting into bamboo strips with an arc-shaped section; softening the bamboo strips by pressurizing and heating, and unfolding the softened bamboo strips at equal arc and fixed thickness; performing double-sided protection and gradual flattening under a condition of heat preservation until the bamboo strip is completely flattened, to obtain a bamboo board; and continuously cooling the bamboo board, shaping the bamboo board under a heavy weight and then drying, and then trimming under a fixed width to obtain the bamboo outer skin-retaining bamboo board finished product. According to the unfolding process of the bamboo outer skin-retaining bamboo strip provided by the present invention, the bamboo outer skin-retaining bamboo strip can be unfolded under the promise of not destroying the bamboo outer skin surface, and there will be no cracking and rebound problems in the unfolding process, so the obtained bamboo outer skin-retaining bamboo veneer is smooth and flat, and has natural and beautiful textures and good mechanical properties, which fills the gap of the lack of natural green bamboo texture materials in the bamboo market.
