Method and apparatus for manufacturing bamboo fiber

Abstract

The aim of the invention is to provide a method for producing bamboo fibre with a certain length in bulk at atmospheric temperature and normal pressure, and a device for producing the same. The method includes forming bamboo strip which integrates fibre and bamboo shoot as a whole, pressing the bamboo strip at intervals of determined length, and carrying out fibrillating after extending the inner bamboo fibre at the press position. Since the intension of the extending part of the bamboo fibre is weakened and can be naturally cut, the bamboo fibre with the same length and determined length intervals can be produced in bulk. In addition, the fibrillating can be easily performed due to weakening combination of the bamboo fibre and bamboo shoot in the bamboo strip by means of vibration, accordingly, the bamboo fibre with a burr shape can be obtained.

Description

technical field [0001] The invention relates to a bamboo fiber production method and a production device for continuously producing bamboo fibers with consistent length in large quantities under normal temperature and pressure. Background technique [0002] Bamboo fiber is a natural resource and has excellent cohesiveness and strength. It is an environmentally friendly fiber that has attracted attention as an automotive interior decoration, building material, and reinforcement material. Bamboo fibers are usually not used alone, but are mixed into raw materials such as plastic fibers for use. Using long bamboo fibers, a product with excellent flexural strength can be obtained. On the other hand, using short bamboo fibers can increase the density of the fibers and can be used as a product for firmly fixing screws or nails. In addition, since the density increases when the fiber is thin, it is related to the improvement of the strength of the product. Moreover, if the bamboo...

Problems solved by technology

Therefore, there is a problem that it is impossible to obtain bamboo fibers that can be used in building materials that require strength, etc.

[0018] In Patent Document 4, just because the bamboo chips pass through the rollers many times and the bamboo fibers are obtained by being crushed, the length of the fibers is not uniform, and the fibers in the specified length range cannot be obtained.

[0019] In addition, for the same reason, the thickness of the fiber is not uniform, so the desired thickness of the fiber cannot be obtained.

[0020] Like this, under normal temperature and pressure, the method and the device of the bamboo fiber of consistent length within a certain range are produced continuously in a large amount at the present stage.
