Whole bamboo flattening method and processing equipment

Abstract

The invention provides a whole bamboo flattening method. The method includes the following steps that firstly, old bamboo which is 3-5 years is selected, after branches are removed, the bamboo is sawn into a bamboo tube with the corresponding length; secondly, the bamboo tube is arranged on the bamboo wood processing equipment, an outer bamboo joint and an inner bamboo joint are removed, bamboo green with the thickness of 2-3 mm is removed, and a groove is formed in the bamboo tube; thirdly, the bamboo tube obtained in the second step is placed in an oven, baked for 5-10 min at the temperature of 300 DEG C to 500 DEG C, and softened; fourthly, the softened bamboo tube is placed on a flattening machine to be flattened, cooled for 20-30 min, and flattened into a bamboo plate in a cold pressing manner; fifthly, bamboo inner skin on the inner surface of the flattened bamboo plate is removed by 3-5 mm in a planing manner, and the outer surface and the periphery of the bamboo plate are ground to be smooth; and sixthly, the bamboo plate is baked for 5-6 hours in a baking room at the temperature of 30 DEG C, baked for 10-11 hours after temperature is raised to 40 DEG C, baked for 2-3 hours when temperature is raised to 50 DEG C, and manufactured into whole bamboo. The outer bamboo joint, the bamboo green and the inner bamboo joint of the bamboo tube are automatically cut off, working efficiency is high, and the processing quality of the bamboo tube is improved.

Description

technical field [0001] The invention relates to the technical field of bamboo and wood processing, in particular to a method for flattening whole bamboo and processing equipment. Background technique [0002] At present, bamboo products are more and more widely used. For example, more and more bamboo cutting boards are made of whole bamboo flattened. Before the bamboo is flattened, it is necessary to cut the bamboo into bamboo tubes, and then remove the outer bamboo nodes. And removing the inner bamboo joints, in the process of the prior art, removing the outer bamboo joints and removing the inner bamboo joints are divided into two processes, which are processed on two machines respectively, so it needs to be positioned and processed twice, which makes the work efficiency low. And for removing the inner bamboo joints, the broken way is adopted, so the inner bamboo joints cannot be completely removed, and the remaining inner surface is not smooth. [0003] And at present the...

[0002] At present, bamboo products are more and more widely used. For example, more and more bamboo cutting boards are made of whole bamboo flattened. Before the bamboo is flattened, it is necessary to cut the bamboo into bamboo tubes, and then remove the outer bamboo nodes. And removing the inner bamboo joints, in the process of the prior art, removing the outer bamboo joints and removing the inner bamboo joints are divided into two processes, which are processed on two machines respectively, so it needs to be positioned and processed twice, which makes the work efficiency low. Moreover, the method of removing the inner bamboo joints is broken, so that the inner bamboo joints cannot be completely removed, and the remaining inner surface is uneven

[0003] And at present the bamboo green removal of the bamboo outer layer is planed after the bamboo is flattened. Before the flattening, the bamboo needs to be baked to make it soft, and then flattened. The green part is difficult to remove; at the same time, the flattened bamboo board is not very smooth. When planing the outer surface of the bamboo board, the thickness of the green bamboo board is not uniform, which has a great impact on the quality of the finished bamboo board after final processing. The impact of reducing the quality of the whole bamboo cutting board
