【正文】 再直接對(duì)采自毛竹原產(chǎn)地的原材料進(jìn)行實(shí)際的數(shù)據(jù)測量和分析。 要想獲得整竹無裂紋展開竹平板，竹筒去青是關(guān)鍵工藝，去青后的竹筒表面質(zhì)量的好壞將 直接影響竹平板的展開質(zhì)量。 1 摘要 近些年由于生活水平的提高，人們對(duì)家居裝飾提出了更高的要求，竹材因其強(qiáng)度高，耐磨性好，紋理清晰美觀，而且為天然綠色環(huán)保產(chǎn)品大大迎合人們回歸自然的心理，深受人們的喜愛，市場前景非常廣闊。為了組織大規(guī)模生產(chǎn)，必須使用合理高效的專用加工機(jī)械，但以竹子為原料生產(chǎn)板材是八十年代才開始研究的課題，到目前為止，最具有代表性的展開法為半竹平板加壓展開法、旋切展開法 2種，對(duì)于最有經(jīng)濟(jì)附加值的整竹無裂紋展開因其難度較大而在國內(nèi)外基木屬于空白。本文所涉及就是力求在遵循竹子特點(diǎn)的前提下，開發(fā)出一套成本低，操作方便，生產(chǎn)效率高，適用于大規(guī)模生產(chǎn)加工的整竹無裂紋展開的竹筒技術(shù)及裝備，從而獲得幅面寬度為 250300mm、厚度為 、長度為 2500mm 的整竹展開竹平板、竹平板刨切薄片及薄片貼面裝飾板。同時(shí)在考慮毛竹竹筒幾何外形不規(guī)則以及材料的特殊性的基礎(chǔ)上對(duì)目前的多種去青加工方法進(jìn)行比對(duì)分析 ，最終選擇了表現(xiàn)最優(yōu)的砂輥磨削方法，為使所設(shè)計(jì)的加工設(shè)備與市場現(xiàn)有設(shè)備相比較具有更好的通用性和操作性，適用各地組織大規(guī)模竹材加工，本文依據(jù)毛竹的特點(diǎn)對(duì)所設(shè)計(jì)的設(shè)備的各部件進(jìn)行優(yōu)化，特別是對(duì)關(guān)鍵的竹筒的裝夾設(shè)備，小型簡易砂輥的特殊結(jié)構(gòu)進(jìn)行了詳細(xì)的設(shè)計(jì)優(yōu)化。由于毛竹“三度”的影響，砂輥隨竹筒外形的變化而浮動(dòng)時(shí)，必然會(huì)引起磨削力的變化。我們根據(jù)上述原則對(duì)拉緊彈簧的 設(shè)計(jì)和安裝位置的選擇進(jìn)行了詳細(xì)分析設(shè)計(jì)。彎曲度越大，浮動(dòng)量越大，引起彈簧的拉力變化就越大，因而磨削力的變化越大，表面加工質(zhì)量就越差。其結(jié)構(gòu)簡單、造價(jià)低廉、可靠性好。一般木材磨削用的砂輥尺寸較大，結(jié)構(gòu) 2 比較復(fù)雜。我們所設(shè)計(jì)的簡易砂輥是針對(duì)整竹去青設(shè)計(jì)的一種特殊砂輥，它不僅工作可靠、性能優(yōu)，而且結(jié)構(gòu)緊湊、重量輕，更換砂布方便、快捷。 本課題研究設(shè)計(jì)出了一種全新的整竹去青加工工藝及設(shè)備，加工獲得整竹表面的加工質(zhì)量理想，適合于無裂紋展開，具有較高的推廣意義。s favorite, the market prospects are very broad. To anize a largescale production, to be rational and efficient use of dedicated processing machinery, but as raw materials to produce bamboo plate is only the beginning of the eighties study, so far, the most representative of the expansion method for the pressure plate to start a half bamboo law, two kinds of expansion method peeling, for most of the entire economic valueadded bamboo and crackfree and more difficult to start because of their base at home and abroad belong to the blank wood. To obtain crackfree to start the whole bamboo bamboo plate, bamboo is the key to green technology, to the postgreen bamboo surface quality will directly affect the quality of the plate to start the quality of bamboo. In this paper, is involved in trying to follow the premise of the characteristics of bamboo, the development of a set of lowcost, convenient operation, high productivity for largescale bamboo production and processing of the whole crackfree start of the bamboo tube technology and equipment so as to attain the size width of 250300mm, a thickness of , length 2500mm started the whole bamboo bamboo plate, bamboo plate Sliced thin veneer sheets and decorative boards. In this paper, the theory and practice through a bination of research methods, first of all characteristics of a large number of Bamboo have access to the information, and then directly taken from the bamboo of origin of raw materials for the actual measurement and analysis of data. At the same time, consider bamboo bamboo irregular geometry and the material basis of the specificity of the current processing of a variety of methods to Green than on analysis, the final choice of the optimal performance of the sand roller grinding methods, designed to make processing equipment and existing equipment pared to the market with better versatility and interoperability for largescale bamboo processing throughout the anization, this article on the basis of the characteristics of bamboo equipment designed to optimize the various ponents, especially for the critical loading 4 of bamboo folder equipment, a small summary of the special structure of sand roller carried out a detailed design optimization. Grinding in to the Green, the grinding force is stretched by the Head of the tension spring the size of the decision. As the bamboo three times the impact of sandroll with the changes in tube shape when floating, is bound to cause changes in grinding force. In order to ensure the quality of bamboo surface grinding, grinding should be made in the course of the changes in grinding force as small as possible, that is, the spring tension of the tension changes as small as possible. In line with these principles, we spring to tighten the design and installation of the choice of the location of a detailed analysis of the design. Or as a result of bamboo39。fixture clamping position was optimized. . General wood grinding roller with a larger size of the sand, the structure is rather plicated. In bamboo processing, it is necessary to design a smaller packagetype sand roll, the grinding diameter 150mm, emery cloth axial width of 100mm. We designed a simple sand roller bamboo for the whole design to the Green Sand of a special roller, it is not only reliable, excellent performance and pact structure, light weight, the replacement of emery cloth convenient, fast. Paper described in detail the characteristics of its structure and focus on the key roll sand flexible parts of the strength and stiffness of ring theoretical analysis and calculation. This research designed a brandnew to the whole green bamboo processing technology and equipment, processing, access to the entire surface of the processing quality bamboo ideal, suitable for crackfree to start the promotion of high significance. Key words: crackfree to start the whole Penny to Qing, grinding, sand roll, design 5 第 1章 緒論 課題研究的目的和意義 隨著經(jīng)濟(jì)的發(fā)展和人們生活水平的提高，社會(huì)對(duì)木質(zhì)材料的需求也大大增加，由此導(dǎo) 致森林“赤字”不斷擴(kuò)大，森林資源質(zhì)量與材種急劇下降，成熟材、優(yōu)質(zhì)材、大徑材不斷 減少。為了解決這一矛盾，急需一種新材料來替 代木材的需求，經(jīng)過長期的調(diào)查和比較，竹子成為人們的第一選擇，因?yàn)榕c木材相比較， 竹子的生長周期短而且易于密植，資源再生速度快，物理力學(xué)性能優(yōu)越，而且我國是世界 上竹子資源最豐富的國家，分布地域相當(dāng)廣泛，資源取
