Processing method for removing bamboo outer skin and bamboo inner skin of bamboo tube

Abstract

The invention provides a processing method for removing the bamboo outer skin and the bamboo inner skin of a bamboo tube. The bamboo outer skin and the bamboo inner skin are removed by rotatably cutting the bamboo tube inside and outside, and bamboo joints inside the bamboo tube are removed in advance before rotary cutting. The processing method comprises the following steps that (a) the bamboo tube is prepared; (b) the bamboo joints are removed; (c) the bamboo outer skin is removed in a rotary cutting mode; and (d) the bamboo inner skin is removed in a rotary cutting mode. The processing method for removing the bamboo outer skin and the bamboo inner skin of the bamboo tube has the advantages that (1) the prepared bamboo tube does not have the bamboo outer skin, the bamboo inner skin or the bamboo joints, can be flattened to manufacture a flawless bamboo plate, and can also be laminated to manufacture a laminated bamboo plate for manufacturing bamboo products such as reconsolidated bamboo; and the bamboo outer skin and the bamboo inner skin, with the same thickness, of an irregular bamboo tube can also be removed, the production efficiency is high, energy consumption in processing is low, and work and time are saved; and (2) the bamboo joints are removed by using a twist bit of an inner roller A, then the bamboo tube is driven to rotate through the rotation of an inner compression roller and an outer compression roller, and the bamboo outer skin and the bamboo inner skin are removed through rotary cutters which are tightly close to the two compression rollers. The processing method for removing the bamboo outer skin and the bamboo inner skin of the bamboo tube provides technical support for manufacturing the bamboo into the flattened bamboo plate and producing the laminated bamboo plate.

Description

technical field [0001] The invention relates to a processing method for removing bamboo green and bamboo yellow from bamboo tubes, and belongs to the technical field of bamboo processing in the wood industry. Background technique [0002] Bamboo is divided into bamboo green, bamboo flesh and bamboo yellow from outside to inside along the radial direction. Bamboo green is mainly a layer of cells outside the bamboo culm wall, which is composed of elongated cells, cork cells, siliceous cells and stomata, about 0.3mm thick. Below is the vascular bundle, which is the densest part of the bamboo wall. Because the vascular bundle has a lot of content, high density, and high growth stress, the green bamboo is hard and difficult to soften, so it is easy to crack during the bamboo tube unfolding process. Secondly, Zhuhuang is mainly composed of extramedullary tissue without fibrous tube bundles, but it is also relatively hard. Therefore, Zhuhuang is a secondary factor leading to crack...

AI Technical Summary

Problems solved by technology

[0005] In the past, there were also methods to remove bamboo green and bamboo yellow. The removal of bamboo green was mainly through wire brushing or planing bamboo green. There were problems of low processing efficiency, labor and material resources, or a large amount of planing, resulting in uneven bamboo tube walls and high energy consumption. Disadvantages, it cannot be applied on a large scale; the removal of bamboo yellow is mainly through boring to remove the bamboo yellow inside the bamboo wall, but this processing method is inefficient, it is difficult to process longer bamboo tubes, the energy consumption is high, and the effect of bamboo yellow removal is poor

[0006] There is no report on the method of simultaneously removing bamboo green and bamboo yellow and node septa efficiently for bamboo tubes
