Embodiment 1

[0035] Step 1: select the fresh Cizhu with a bamboo age of 8 months;

[0036] Step 2: remove the bamboo tips and elbows from the whole bamboo material that has a small difference in diameter between the head and the tail, and cut it into 350 cm bamboo tubes 200 with an electric saw, and remove the bamboo partitions by perforating;

[0037] Step 3: Put the bamboo tube 200 into a clear water pool for steaming, the heating temperature is 95°C, and the heating time is 15 minutes. The outer wall of the bamboo tube 200 turns yellow-gray, and then it is taken out immediately;

[0038] Step 4: Flip out the fibers:

[0039] A. Take the softened bamboo tube 200, fix one end of the bamboo tube 200, extend the expansion air bag 1 into the other end inner wall of the bamboo tube 200 by 5 cm, inflate the expansion air bag 1, and the expansion air bag 1 utilizes air pressure to push the bamboo tube 200 side Crack and disperse, and then use the metal tube 2 to push into the opened inner wall...

Embodiment 2

[0043] This part differs from Example 1 in that:

[0044] Step 1: select bamboo age to be 2 years moso bamboo;

[0045] Step 2: Use a chainsaw to cut into a 50cm bamboo tube;

[0046] Step 3: Heating temperature 100°C, heating time 45min;

[0047] Step 4: Flip out the fibers:

[0048] A. Stretch the expansion air bag 1 into the other end inner wall of the bamboo tube 200 by 15cm

Embodiment 3

[0050] This part differs from Example 1 in that:

[0051] Step 1: select bamboo age to be 1.5 years moso bamboo;

[0052] Step 2: Use a chainsaw to cut into a 200cm bamboo tube;

[0053] Step 3: The heating temperature is 100°C, and the heating time is 25 minutes.

[0054] Step 4: Flip out the fibers:

[0055] A. Stretch the expansion air bag 1 into the other end inner wall of the bamboo tube 200 by 10cm

Abstract

The invention discloses an outward turning device for a bamboo tube. The outward turning device comprises an expansion air bag and a metal tube, wherein a rubber air bag is circularly arranged on the inner wall of the metal tube, and the rubber air bag is fixedly connected to the inner wall of the metal tube; an outward turning and splitting method using the outward turning device for the bamboo tube specifically comprises the following steps of selecting materials, cutting, softening, and outwards turning and splitting. According to the method and the device, splitting of the softened bamboo tube is forced by fully utilizing mechanical external force and stress synergistic effect generated by large deformation due to outward turning of the bamboo tube, and the produced bamboo fibers are neat, integrated and controllable in length.

Description

technical field [0001] The invention relates to a bamboo tube eversion device and a method for opening bamboo tubes by using the bamboo tube eversion device. Background technique [0002] At present, most of the production methods of bamboo raw fibers adopt chemical methods or mechanical chemical fiber opening methods. During the fiber opening process, chemical modification needs to be carried out first, and then mechanical equipment is used to decompose (or roll) bamboo into fiber form. Because chemical treatment often brings huge pollution, and in the process of mechanical processing, cutting blades or rolling rollers will destroy the structure of bamboo, so that the obtained fibers present fatal defects such as thick, short, hard, etc., and their uniformity cannot meet the needs of textile production. fiber requirements. Contents of the invention [0003] One of the technical problems to be solved by the present invention is to provide a bamboo tube eversion device, wh...
