Abstract

A device for straightening a bamboo (7). A part to be straightened of the bamboo (7) is first heated by means of a heating furnace (3), and then the bamboo is pushed forward to be fed so that the heated part to be straightened is positioned between an upper straightening assembly and a lower straightening assembly, which correspondingly press the upper surface and the lower surface of the part to be straightened of the bamboo, thereby achieving straightening of the bamboo. The technical problem that according to existing bamboo straightening methods, bamboo straightening is implemented mainly by virtue of manual work, such that the bending points of a bamboo are so difficult to be controlled that the bending points of the bamboo culm may be deviated or curvatures of the bamboo may not be at the same plane is solved. As a result, the problems that the bamboo is bent more and more seriously as the bamboo is adjusted, the yield is low, and the production efficiency is low are avoided.
