But there is no denying the fact that waste also contains a minerals to be reckoned with, through the garbage disposal process, can break down a lot of recycling material, this is our country proposed to build a conservationminded society, can make a great contribution. So, the problem of waste disposal is a major problem to be solved. in our country, the garbage is mon in certain specifications of the plastic bags. Trash to the landfill, the first step is to garbage bags broken bag processing, and for a long time in China by way of broken bag is manual handling. This way of broken bag of a lot of shortings, such as work progress slowly, cause harm to workers health, much to recycling material damage, etc. But with the improvement of science and technology in our country, many large landfill also adopted a new way of broken bags, such as laser torn bags. this paper designed a spindle for garbage bag machine, vertical diameter can be realized within a certain range of garbage bags broken bag processing, so that the inside of the garbage exposed, for the next working procedure. This garbage bag machine main structure by the motor, belt pulley, knives, plate, shaft, shaft bracket, steel drum and other major parts. Secondly, this paper considered the collision avoidance problem of cutting tool and the winding device design problems, in order to better for garbage bags broken bag processing. keywords: garbage。 Vertical。 The winding 內(nèi)蒙古工業(yè)大學(xué)本科畢業(yè)設(shè)計說明書 目 錄 緒 論 .............................................................. 1 第一章 垃圾破袋機(jī)的結(jié)構(gòu)設(shè)計 ........................................ 2 工作原理 ................................................... 2 總體方案設(shè)計 ............................................... 2 傳動部分 的介紹 ............................................. 3 主軸部分的介紹 ............................................. 4 破袋部分的介紹 ............................................. 4 第二章 各組成零件的選擇與設(shè)計計算 ................................... 6 電動機(jī)的選擇 ............................................... 6 皮帶輪的設(shè)計計算 ........................................... 6 楔鍵的尺寸與校核 .......................................... 11 鋼桶及支架尺寸材料 ........................................ 12 刀盤及刀片尺寸 ............................................ 12 主軸與軸承的強(qiáng)度校核 ...................................... 13 主軸的壓桿穩(wěn)定問題 .................................. 13 主軸的抗彎扭校核 .................................... 14 軸承的校核 .......................................... 16 第三章 刀具的避讓與防纏繞裝置 ...................................... 17 刀片避讓機(jī)構(gòu)的工作原理 .................................... 17 破袋刀片的布置及形狀 ...................................... 18 防纏繞裝置 ................................................ 18 第四章 相關(guān)軟件的介紹 ............................................. 20 CAXA 電子圖版 ............................................. 20 結(jié) 論 ............................................................. 21 參考文獻(xiàn) ........................................................... 22 致 謝 .....
