Method and equipment for removing green bamboo on bamboo tube surface

Abstract

The invention provides a method and device for removing the green skin on the surface of a bamboo tube. The method includes the steps of making sand particles tightly surround the surface of the bamboo tube and making the sand particles move relative to the bamboo tube so as to generate friction and remove the green skin on the surface of the bamboo tube. The device comprises a sand container and a driving mechanism. The sand container is used for containing the sand particles and can contain the bamboo tube to be processed so as to make the sand particles tightly surround the surface of the bamboo tube. A sand inlet for adding the sand particles is formed in the sand container. The driving mechanism is used for driving the bamboo tube to move relative to the sand container so that friction can be generated between the bamboo tube and the sand container. The green skin removing quality and efficiency of the bamboo tube are improved, the effective utilization rate of the bamboo tube is increased, the processing cost is low, the influences on the working environment are small, the method and the device can be widely applied to the industries of bamboo products such as container floors and building templates, and the economic benefits are remarkable.

Description

technical field [0001] The invention relates to the field of bamboo tube processing, in particular to a method and equipment for removing green bamboo on the surface of bamboo tubes. Background technique [0002] Bamboo is an important forestry product that is fast-growing, high-quality, and easy to regenerate and restore natural resources. Bamboo is a hollow cylindrical structure with thin walls, the outer wall is bamboo green surface, the inner wall is bamboo yellow surface, and the part between bamboo green and bamboo yellow is bamboo flesh. Because the hardness of bamboo is greater than that of wood, bamboo is often processed into floors to replace traditional wooden floors, and because bamboo walls are thinner, it is usually necessary to glue multiple pieces of flattened bamboo together or It is interlaced with wood to obtain plywood with a certain thickness and size. However, because the bamboo green on the surface of the bamboo is difficult to glue, it must be remove...

AI Technical Summary

Problems solved by technology

[0003] At present, the treatment process of removing bamboo green is mainly realized by cutting (milling cutter or blade, etc.). For naturally growing bamboo, its surface is uneven, its shape is irregular, and the wall thickness of the same bamboo is different, which is easy to cause cutting. The knife is fragile, the force of the cutting knife is uneven, and the cutting surface is not completely processed, etc.

In order to solve this problem, it is necessary to frequently adjust the angle and height of the cutter or replace the blade, etc. However, frequent adjustment of the cutter will cause cumbersome procedures and waste manpower and material resources on the one hand, and will greatly reduce the processing efficiency of bamboo on the other hand; moreover, because bamboo is natural The growing material has an arc-shaped surface with different arc radii, and the thickness of the bamboo is not exactly the same. The tool cannot be fully adapted. Cutting will cause uneven force on the tool and different cutting thickness. In order to make the surface of the bamboo more smooth and smooth , it is unavoidable to cut the bamboo to be thinner, but this will reduce the utilization rate of bamboo, so that the utilization rate of bamboo can only reach 60%~70% at most; in addition, because the hardness of bamboo gradually increases from the outside to the inside, using The cutting method to remove bamboo green will cut off most of the hardest bamboo meat part of the outer layer of bamboo

[0004] In addition, at present, it is also considered to remove the green bamboo by spraying sand particles into the bamboo tube. Although this method can improve the utilization rate of bamboo, the energy consumption required for spraying sand particles is too high, and the processing cost of a single bamboo tube is too high. Larger dust requires additional treatment, and the dust will also deteriorate the environment in the workplace and have a certain impact on the health of the staff
