Abstract
The present invention relates to a bamboo rounding and straightening method which orderly comprises the following process flow of interception, segment removal, softening and shaping, cooling and forming for standby or immediate flake rotary cutting. The shaping, the forming and the rotary cutting in the method are all carried out on a normally used rotary trunk-layer stripping machine without a clamper for cutting a single plate, Compared with rotary cutting of an original bamboo, the present invention has high use rate of the bamboo; compared with the method that after a square material is leveled and a flat plate is spread, the bamboo is glued into an integrated material, and a bamboo single plate is obtained through slicing. The present invention has the advantages of few procedures, saved equipment investment, low cost, high work efficiency and wide and long amplitude surface of the cut single plate.
Description
Technical field
The present invention relates to a kind of method of using the technology of high-temperature pressurizing with bamboo trimming, straightening.
Background technology
With bamboo rotary cutting thin slice (bamboo veneer), need from bamboo grove, to select not only circle but also straight bamboo and make raw material, those curved, cross section ovalizes or difform, give it up (choosing).In fact, when bamboo grove is selected round and straight bamboo, be subjected to placing restrictions on of naked eyes judgement, selected bamboo is still very not round, very straight yet, also influences the utilization rate of bamboo wood during rotary-cut thin slice (bamboo veneer) to a certain extent.Recently, have bamboo wood is launched the well-thought-out plan flat board, compose integrated timber slicing thin slice again; Also useful bamboo wood is made square material through blocking, going after joint, drying, filling, shaping, the cooling, vertically again being split into sheet material, makes integrated timber then and carries out the slicing thin slice.These two kinds of methods all need be made integrated timber slicing thin slice again, and the thin slice breadth that is obtained is narrow, and the cost height of making, work efficiency are low." forest product industry " 2004 the 31st the 2nd phases of volume disclose " research of shaping bamboo " technology that is made into square material of Tang Jun Mr. fear.CN012724173 discloses Moganshan Package Co Ltd, Deqing County's " whole bamboo spreading bamboo veneer slicing thin slice " technology, just belongs to above-mentioned two kinds of modes of production.
Summary of the invention
The objective of the invention is above-mentioned deficiency at prior art, design a kind of can be when producing the bamboo thin slice, than the utilization rate of bamboo height of former bamboo rotary-cut thin slice, flatten slicing and the slicing of shaping square bar economizes operation, province's equipment investment, the sake breadth is wide and length, bamboo trimming and straightening method that work efficiency is high than whole bamboo.
Purpose of the present invention can realize with following measure: its technological process is followed successively by:
(1) former bamboo intercepting, requiring the bamboo segment length is 0.4-1 rice, the girth at section bamboo two ends is poor＜6mm, adopt the intercepting of disk finishing mandrel;
(2) remove ring, remove acromere earlier, break interior onion again, remove internal segment and do not require and mill flatly, beat a bigger hole and get final product, the acromere millable, scrape, sand flat;
(3) thermoplastic is carried out in digester or boiling pond or pressure cooker, and it is softening with favourable acceleration to mix ammonia, and logical 120-170 ℃ of steam needs 15-60min to finish softening;
(4) shaping while hot, the Duan Zhu that thermoplastic is finished sends in the shaping setting peeler immediately while hot, withdraws from and revolves cutter 1, rotates shaping under the 1.5-5Mpa pressure of at least three driving shaping pressure rollers;
(5) cooling shaping, the hot arc bamboo in shaping is through constantly rotation, and heat radiation is cooled off, and rotation is cooled to 50-60 ℃, and setting is finished.
Described shaping setting peeler is for the rotary trunk-layer stripping machine without clamper of rotary cut venner commonly used, as the trimmer of bamboo trimming and straightening.
Description of drawings
Accompanying drawing is a shaping setting peeler primary structure schematic diagram of the present invention.
The specific embodiment
The present invention is described in detail below in conjunction with embodiment and with reference to accompanying drawing: the bamboo that selects the 3-6 age earlier, the characteristics that taperingness big (base portion and taper diameter differ greatly) arranged because of bamboo, the general requirement section of former for this reason bamboo intercepting bamboo length is 0.4-1 rice, the girth difference at section bamboo two ends is less than 6mm, and the size at such section bamboo two ends is more even.For making section bright and clean smooth, with the intercepting of disk finishing mandrel.Remove acromere earlier for section is bright and clean, break internal segment 4 again, remove internal segment and do not require and mill flatly, beat a bigger hole 5, favourable logical steam, boiling water and avoid explosion to get final product.The acromere millable, scrape, sand flat.Thermoplastic can be carried out in digester (pond), or carries out in pressure cooker, if mix the into composition of ammonia, then can shorten the softening time greatly.Then finish softening as logical 120-170 ℃ of steam through 15-60 branch clock time, immediately section bamboo 3 is sent into while hot in the shaping setting peeler, withdraw from and revolve cutter 1, under the 1.5-5Mpa pressure effect of at least three driving shaping pressure rollers 2, Ruan Hua Duan Zhu is out of shape to circle and straight direction under the acting in conjunction of heat, pressure, hot arc bamboo in shaping is through constantly rotation, play the effect of heat radiation cooling, when a section bamboo temperature drops to 50-60 ℃, finish the setting stage, that is to say that the section bamboo of this moment can take off the standby cutter 1 propelling rotary-cut thin slice that maybe will revolve.Because the section bamboo two ends diameter behind the straightening full circle is even, bamboo wood is straight, the utilization rate of rotary-cut thin slice just shows slightly the utilization rate height of former bamboo curved and that do not justify than shaping not.
Bamboo rotary cutting thin slice behind trimming and straightening than flatten, perfect square make integrated timber again the operation of slicing thin slice lack, low equipment investment, the thin slice breadth that cost is low, work efficiency is high, be cut into is wide and long.
Claims (2)
1. bamboo trimming and straightening method is characterized in that technological process is followed successively by:
(1) former bamboo intercepting requires the bamboo segment length to be 0.4-1 rice, and the girth at section bamboo two ends is poor＜6mm, adopt the intercepting of disk finishing mandrel;
(2) remove ring, remove acromere earlier, break internal segment (4) again, remove internal segment and do not require and mill flatly, beat a bigger hole (5) and get final product, the acromere millable, scrape, sand flat;
(3) thermoplastic is carried out in digester or boiling pond or pressure cooker, and it is softening with favourable acceleration to mix ammonia, and logical 120-170 ℃ of steam needs 15-60min to finish softening;
(4) shaping while hot, the Duan Zhu (3) that thermoplastic is finished sends in the shaping setting peeler immediately while hot, withdraws from and revolves cutter (1), rotation shaping under the 1.5-5Mpa pressure of at least three driving shaping pressure rollers (2);
(5) cooling shaping, the hot arc bamboo is through constantly rotation in shaping, and heat radiation is cooled off, and rotation is cooled to 50-60 ℃, and setting is finished.
2. bamboo trimming and straightening method as claimed in claim 1 is characterized in that the rotary trunk-layer stripping machine without clamper of described shaping setting peeler for rotary cut venner commonly used, as the trimmer of bamboo trimming and straightening.
