The invention discloses a kind of process that bamboo wood flattens in length and breadth, thick bamboo tube is successively truncated, removes internal segment, removes acromere and is gone bamboo blueness to handle by S01；The thick bamboo tube that S01 is handled well is carried out longitudinal direction and cracked, and carries out hot mastication processing by S02；Thick bamboo tube after the softening of S02 high temperature is carried out longitudinal pre- flattening by S03；The thick bamboo tube flattened in advance longitudinal in S03 is carried out lateral flattening by S04；It is dry to be carried out two-sided planing, pressurization fixation and stacking by S05 for the thick bamboo tube laterally flattened in S04.The process that a kind of bamboo wood provided by the invention flattens in length and breadth using longitudinal respective advantage flattened and laterally flatten, and cooperates relevant softening process, the multistage flattening for realizing Mao bamboo tube, solves original production technology operational hazards, volume recovery is low, effect is bad, inefficient equal disadvantage.
Description
Technical field
The present invention relates to a kind of processes that bamboo wood flattens in length and breadth, belong to BAMBOO UNFOLDING technical field.
Background technique
China is the big country of bamboo kind a plant and bamboo industry, and Bamboo products are closely related with people's lives, penetrate into
The every aspect of the clothing, food, lodging and transportion -- basic necessities of life of common people.However the thin hollow structure of wall that bamboo wood is natural, and outer surface has bamboo green, and inside has
Bamboo every and tabasheer, these characteristics all bring difficulty to the processing of bamboo wood.At this stage in production moso bamboo chopping block, general bamboo flooring, bamboo
In the product process such as integrated timber, in order to improve the surface aesthetics of product, the loss for cuing open bamboo is reduced, moso bamboo surfaces externally and internally is reduced and cuts
The amount of cutting, the whole utilization rate and production efficiency for improving bamboo wood, needs to flatten moso bamboo.However, the prior art is single
Longitudinal flattening in suitable bamboo fiber direction needs to carry out indentation in moso bamboo inner surface, and the bamboo clappers after flattening has compared with drastic crack
Line, slicing amount are larger；Enterprise is more carried out using the single method laterally flattened perpendicular to bamboo fibre direction simultaneously
Production, but this method needs to scribe deeper groove at the back side of bamboo wood using pressure roller to prevent the cracking after flattening, and
Thick bamboo tube pre-formed members into after crossing softening process are difficult to open, and need worker to be open using tamper tool moso bamboo, then fill in transverse direction
The risk of flattening machine, the operation is very big, and worker's finger repeatedly occurs and is involved in the accident of lateral flattening machine, and joined worker
Sled mouth process, easily thick bamboo tube is made to crack, and greatly reduce and production efficiency and improve risk.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of existing technologies, provide a kind of safe and efficient, flattening effect
The process that the bamboo wood that fruit is good, utilization rate of bamboo is high flattens in length and breadth.
In order to solve the above technical problems, the technical solution adopted by the present invention are as follows:
A kind of process that bamboo wood flattens in length and breadth, comprising the following steps:
Thick bamboo tube is successively truncated, removes internal segment, removes acromere and is gone bamboo blueness to handle by S01；
The thick bamboo tube that S01 is handled well is carried out longitudinal direction and cracked, and carries out hot mastication processing by S02；
Thick bamboo tube after the softening of S02 high temperature is carried out longitudinal pre- flattening by S03；
The thick bamboo tube flattened in advance longitudinal in S03 is carried out lateral flattening by S04；
It is dry to be carried out two-sided planing, pressurization fixation and stacking by S05 for the thick bamboo tube laterally flattened in S04.
It in S01, goes that stop collar is installed on the green cutter spindle of bamboo blueness processing and applies the air pressure of 0.3~0.7MPa, go green thickness
Degree is 0.4~0.6mm.
In S02, longitudinal direction is carried out to thick bamboo tube using saw blade sawing and is cracked, the width longitudinally to crack is 1~3mm；High temperature is soft
Change processing carried out in closed pressurized canister, heatings and softening medium be saturated vapor, temperature be 160~180 DEG C, handle the time be
5~20min.
In S03, longitudinal pre- flattening supports thick bamboo tube using flattening carrying roller and nip rolls, flattening carrying roller, and thick bamboo tube cracks upward, exhibition
Plain-barreled roll lower part is wedge structure, and nip rolls moves downward, and 100~120mm is reached in thick bamboo tube extension of cracking.
In S04, laterally flattening is squeezed using the adjustable upper nip rolls of spacing and lower nip rolls.
In S05, with a thickness of 0.1~0.2mm, drying mode is to take dry kiln dry for planing.
Beneficial effects of the present invention:
1, by it is longitudinal crack, movement is pried open and filled in hot mastication and longitudinal pre- flattening instead of worker so that
The labor intensity of worker reduces significantly, and the labour that worker is also reduced while reducing labour process is dangerous, machine will not occurring
The phenomenon that device clamp hand, occurs.
2, the recovery effects for reducing BAMBOO UNFOLDING combine the moso bamboo of flattening road after identical by vertical and horizontal
After treatment process, transverse curvature reply is smaller than single flattening treatment process, also just improves the utilization efficiency of bamboo wood.
3, the depth of indentation inside bamboo wood can be reduced using stepped total laterally flattening, to improve moso bamboo after flattening
Globality, improve the physical and mechanical property of final products.
4, the time of sofening treatment is reduced, slicing thickness is reduced, improves the utilization rate of bamboo wood.
