The invention discloses a bamboo shaping device for rotary cutting and a bamboo shaping rotary-cutting method. The bamboo shaping device comprises an internal engaging clamping shaft, a pressurizing driving device used for driving the internal engaging clamping shaft to radially expand and rotate, a pressure control device used for controlling the pressurizing driving device, three or more synchronous motion shaping rollers evenly distributed in the circumferential direction of the internal engaging clamping shaft, a synchronous driving mechanism used for driving all the synchronous motion shaping rollers to move synchronously in the radial direction of the internal engaging clamping shaft, and a shaping roller power control mechanism for providing power for the synchronous driving mechanism and controlling the pressure applied by the synchronous motion shaping rollers to bamboo sections. The bamboo shaping rotary-cutting method comprises the following steps that the bamboo sections with inner and outer joints being removed are softened, initial shaping is conducted, shaping and shape fixing are conducted, and the bamboo sections are rotated to produce bamboo veneer. The bamboo shaping device for rotary cutting is simple in operation method, good in shaping effect and large in driving torque, the phenomena of warping, sliding and the like of a bamboo are avoided in the rotary cutting process, the irregular bamboo sections can be subjected to rotary cutting, and the bamboo veneer is high in outturn percentage, good in quality and numerous in specification.
Description
technical field [0001] The invention relates to the technical field of main material processing, in particular to a bamboo shaping device for rotary cutting and a bamboo shaping and rotary cutting method. Background technique [0002] The wall thickness of bamboo is small, the thinner is only 5mm, the thicker is about 20mm, and the average thickness is about 10mm. The roundness and straightness of bamboo largely determines the yield rate of bamboo veneer. The proportion of bamboo with good roundness is very low in natural bamboo. The yield rate of rotary-cut bamboo veneer is low and the price is relatively high. Expensive, the market demand is small. By rounding and straightening the bamboo material, the output rate of the rotary-cut bamboo veneer can be improved, the price of the bamboo veneer can be reduced, the market competitiveness of the bamboo veneer can be improved, and the development of the bamboo industry can be promoted. The existing type of rotary cutting mach...
