【正文】 I 摘 要 本次課題設(shè)計(jì)的 是 折蓋 封 箱 機(jī)，采用 兩側(cè)皮帶驅(qū)動(dòng) 來進(jìn)行 折蓋 封箱的方案 ，上下封箱、經(jīng)濟(jì)、快速、平穩(wěn) 。這種方案在技術(shù)上 是 相當(dāng)成熟的一種 ，它被 廣泛應(yīng)用于生產(chǎn)實(shí)際中。這次設(shè)計(jì)的 折蓋封箱 機(jī)，可以 根據(jù)紙箱規(guī)格，手 動(dòng) 調(diào)節(jié)寬度及高度，可單機(jī)作業(yè)，也可與 自動(dòng)化 包裝 流水 線配套使用。工作時(shí)， 當(dāng)箱體進(jìn)入工作空間后， 由光電開光控制推桿 使折蓋機(jī)構(gòu) 折合 箱體 ， 當(dāng) 箱體 運(yùn)行至刀架位置時(shí)，箱體將刀架和前膠帶壓輪壓退位，而后膠帶壓輪在四桿機(jī)構(gòu)的作用下與前膠帶壓輪保持同步運(yùn)動(dòng)而退位，并使前面的膠帶與紙箱貼合并封箱。隨著箱體前進(jìn)，膠帶不斷地抽出封在 箱體上。當(dāng)箱體的后部離開刀架 時(shí)，前膠帶壓輪由于四桿機(jī)構(gòu)的作用與后膠帶壓輪的運(yùn)動(dòng)一致，而刀架受彈簧彈力作用，復(fù)位彈起，切斷膠帶。當(dāng)箱體運(yùn)動(dòng) 至 離開后膠帶壓輪時(shí)，后膠帶壓輪也由于受可調(diào)彈簧回位作用而復(fù)位，使連在箱體上最后的膠帶也貼在箱體上，完成后段封箱任務(wù)。 該論文詳細(xì)說明了本次封箱機(jī)設(shè)計(jì)的步驟及其依據(jù)。包括設(shè)計(jì)方案的選擇、 折蓋機(jī)構(gòu)的設(shè)計(jì)、 電機(jī)的選擇、 工作臺部件的設(shè)計(jì)、頂式部件設(shè)計(jì)和刀片的設(shè)計(jì)。 關(guān)鍵詞： 折蓋 封箱機(jī)； 折蓋機(jī)構(gòu)； 四桿機(jī)構(gòu)；刀架部件；刀片設(shè)計(jì) II Abstract The packing box sealing machine that this subject is designed, adopt both sides belt to drive to carry on the scheme of a box, seal the box, economy, fast, steady up and down. This kind of scheme is applied to producing in reality extensively, is a quite ripe one technically. The packing box sealing machine designed this time, can regulate width and height by hand,according to the carton specification, but unit homework, can also pack the assembly line to use with automation tegether. Work, when the box into the working space, the box at the side of the toothed belts advance under friction. When run to the turret position, box blade frame and pressure roller pressure to step down before the tape, but after the knife and tape roller in the role of fourbar mechanism with a tape roller under the synchronized movement to abdicate, and to front .The tape and carton sealing paste the merger. With the advance box, tape keep out letters in the box on. When the box from the back of the blade, the first tape roller as the role of fourbar linkage with the movement of the roller after the tape line, the blade holder by a small spring elastic effect reset the bounce and cut tape. When the cabi after the departure of tape roller sports, the posttape roller is also adjustable spring back due to the role of the reset bit, so even the last of the tape in the cabi are also posted on the box, the pleted section of sealing task. he paper details the design of this sealing machine steps and its basis. Including the choice of design, motor selection, workbench ponent design, ponent design and topstyle blade design. Keywords: Sealing machine。 fourbar linkage。 table ponents。 turret ponents。 blade。 III 目 錄 摘要 .............................................................................................................................................
