The present invention relates to a bamboo processing apparatus, and more particularly, to a bamboo processing apparatus for removing the nodes of bamboo and flattening the bamboo.

As is well known, bamboo is a woody plant, and the fibers constituting it have no radial structure and all the fiber arrangements are configured in the vertical direction.

In addition, only a part of the node of the bamboo is composed of fibers of the spinning and annular tissue, and the fibers in the vertical direction continue to extend through the node.

Bamboo consists of cellulose and hemicelluloid (approximately 60% to 64%), greenin (approximately 20% to 22%) and other (approximately 14% to 20%), and the fiber of cellulose and hemicellulose and green Nin forms an amorphous matrix.

The medium of bamboo is an amorphous crosslinkable polymer that has a certain degree of moisture and relatively soft state at high temperature.

When tensile strain or compressive strain is applied to the softened bamboo medium, the strain is different depending on the softening degree.

In any case, however, when a tensile force is applied to the bamboo medium, breakage occurs in a range of 1 to 2% of elongation in the direction parallel to the fibers (fiber direction, tree direction) or in the direction perpendicular to the fiber.

Therefore, the processing of applying a large strain to the bamboo is mainly limited to the compression processing, and furthermore, the processing of the bamboo is not easy because the aperture diameter, thickness, and intervals between nodes differ.

Therefore, conventionally, it was common to divide the circumference of bamboo into 1/2 or 1/4 and use it as a board | plate material. This is because cracking occurs when bamboo is flattened due to the structure of bamboo, particularly, because cracking occurs easily due to the thickness difference between the inner and outer diameters of bamboo.

In addition, in order to use bamboo as a flat plate wood, the work of removing the bamboo node should be preceded.

Bamboo nodes should be cut to equal the thickness of the bamboo. However, removing the nodes of bamboo is also more difficult because the diameter of the bamboo is not constant for each part and it does not form a garden.
