Problems solved by technology

[0003] It is a recent popular trend to process bamboo into bamboo tow and then further produce bamboo products, especially bamboo plywood. Several processes cannot be separated from the forming socket of forming bamboo slices first and then forming tow, so the work efficiency is very low

Embodiment 1

[0024] Embodiment 1: with 4 years old moso bamboo diameter at breast height 80mm, cut length 80mm bamboo section, one by one rolling pressure longitudinal crack, insert the inner liner core of the special clamp of the present invention that matches with this bamboo section tightly with diameter and insert two longitudinal crack bamboo sections In the hollow end, move it to a common lathe, and clamp it on the outer clamp body of the special fixture of the present invention on the headstock and tailstock respectively. The tailstock is in a state that can reciprocate and move along the track. When the forward twist angle reaches 65°, it will automatically turn +65°counterclockwise, and then turn back to clockwise. In this way, the bamboo filaments will be formed by twisting each forward and reverse twice. At the same time, the positive and negative conversion and rotation , The tailstock moves back and forth due to the twisting and deformation of the bamboo segment. Then remove t...

Embodiment 2

[0025] Embodiment 2: use 5 years old diameter at breast height 180mm moso bamboo section length to be the bamboo section of 2500mm, rolling flat longitudinal split, with the mold that diameter matches with this bamboo section diameter, the S19 inches that Zhenjiang machine tool factory produces, 482 * 3000 common lathes Twist the front and back three times in the middle, and the torsion angle is 75 °. As in Example 1, the bamboo tow is obtained, cut and flattened, and the green and yellow of the bamboo are removed, which is used as a raw material for reorganizing the reinforced molding.

Embodiment 3

[0026] Embodiment 3: use 5 years old diameter 100mm Phyllostachys pubescens basal excess material (Φ about 120mm) or tip surplus material (Φ about 80mm), cut into 300mm bamboo section (utilize as edge material), classify respectively and use flat press for fracturing , each of which is fixed on the rotating and fixing parts of the ordinary lathe with a matching fixture of diameter, and twisted alternately in the positive and negative directions, and the moving part moves back and forth along the slide rail, as in Example 1. , remove the internal fragments, do not use double-sided planing, do not remove bamboo green and bamboo yellow, and use it as the core material of layered bamboo plywood or other composite boards.

Abstract

The invention relates to the bamboo tows highly efficient production method that comprises the cutting, vertical crack, end clamping, active twisting, section and spreading, cutting the bamboo into sections of 300-2500mm, rolling and flattening to crack the bamboo, using outside clamping body and the liner core formed special fixture fixing both ends of the bamboo section, turning common lathe to bamboo section twisting machine, bamboo fiber twisting 40-75degree for 1-3 times, spreading or sectioning to clean the chops inside to get the tows to be the material for bamboo laminated board with significant improvement in productivity and application.

Description

technical field [0001] The invention relates to a method for producing bamboo tow with high work efficiency and its core machinery and clamps. Background technique [0002] The production of bamboo plywood with bamboo as raw material has a process from rough to refined. Earlier, the thin slices of bamboo were used as raw materials, thick bamboo plywood arranged in the same longitudinal direction, and thin bamboo slices were criss-crossed and layered. Arranged bamboo plywood, bamboo plywood glued together after weaving into bamboo mats, and bamboo plywood laminated with thicker bamboo sheets for bamboo flooring. The above bamboo plywood is made of thick and thin bamboo sheets. The board produced has obvious flake marks and rough texture, which is not suitable for making high-end furniture and high-grade floors. Taking bamboo slices as raw materials has a large amount of processing, many procedures, low utilization rate of raw materials, and the pressed boa...
