I摘 要本次課題設(shè)計的是自動折蓋封箱機(jī)，采用兩側(cè)摩擦帶驅(qū)動來進(jìn)行封箱的方案，上封箱、經(jīng)濟(jì)、快速、平穩(wěn)。這次設(shè)計的自動折蓋封箱機(jī)，可以根據(jù)紙箱規(guī)格，通過感應(yīng)裝置調(diào)節(jié)寬度及高度，可單機(jī)作業(yè)，也可與 自動化包裝流水線配套使用。工作時，把紙箱從機(jī)臺輸入端推入（箱子頂部的封口蓋須豎起），被輸送帶帶動時松開手，當(dāng)紙箱碰到后折蓋控制開關(guān)時，氣缸活塞伸出，推動后折蓋板升起，當(dāng)紙箱完全經(jīng)過后折蓋控制開關(guān)時，后折蓋控制開關(guān)復(fù)位，此時氣缸活塞收縮，后折蓋板落下，壓住紙箱后蓋，紙箱兩側(cè)蓋在擺桿作用下完成側(cè)蓋折蓋動作，即可完成折蓋封箱目的。折蓋順序為：前蓋、后蓋、左右側(cè)蓋。當(dāng)箱體運(yùn)行至刀架位置時，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，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)動至離開后膠帶壓輪時，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)計的步驟及其依據(jù)。包括設(shè)計方案的選擇、電機(jī)的選擇、工作臺部件的設(shè)計、折蓋封箱部件、頂式部件設(shè)計和刀片的設(shè)計。關(guān)鍵詞：封箱機(jī)；四桿機(jī)構(gòu)；工作臺部件；刀架部件；刀片設(shè)計；折蓋封箱部件；折蓋順序IIAbstractThis topic is the design of case erector, using both sides of friction tape drive to seal box scheme, sealing, economic, fast, stable. The design of the automatic folding cover sealing machine, can according to the carton size, adjust the width and height by induction device, stand-alone operations, also with the use of automated packaging lines matching. When working, the carton from machine input into (the top of the box sealing cover should be erected by the conveyer belt drives), when let go, when the carton folding cover after the encounter, control switch, push the cylinder piston out, folded plate rise, when the carton completely after folding cover the control switch, control switch after folding cover reset, the cylinder piston shrinkage, folded plate down, the box cover, box cover on both sides of the swing rod completed under the action of the side cover folding cover action, can complete the folding cover sealing purpose. Fold cover order: front cover, back cover, left and right side cover. When the operation to the rest position, the box will rest and tape pressing wheel pressure to resign, then tape pressure acting on the four bar mechanism with the tape pressing wheel wheel keep synchronous movement to abdicate, and make the tape and cardboard box in front of the paste with sealing. As the body forward, constantly taking tape sealed in the box. When the rear part of the box body left the rest, before the tape pressing wheel due to motion consistent tape pressing wheel four bar mechanism and tool, and acting, spring return bounce, cut off the adhesive tape. When the movement to the left after the tape pressing wheel, tape pressing wheel also due to adjustable spring return and reset, so that even in the case the last tape affixed to the box body, box sealing task completed section. This paper details the steps and the basis of this sealing machine design. Including the choice of design, motor selection, workbench component design, folding cover sealing parts, the top part design and blade design.Keywords: sealing machine; four bar mechanism; table part; turret components; blade design; bending cover sealing cover folding sequence compon
