【正文】 structural design, structural design to wear a sword 3, 4 sent back with the structural design, structural design of the adhesive strapping, and part of them structural improvements. Wear a sword structural design using a precision ball screw drive, it does not appear when you shake the longer the trip, the scan will help ensure accuracy, movement stable hybrid stepping motor directly connected to a ball screw, respond more quickly and accurately, while because there is no intermediate member, the mechanical structure can be simplified and high precision. Send back with anizations to adopt gear, tying mechanism uses a cam mechanism, enabling the entire product packaging work. Keywords: packaging technology, wearing swordtype balers, wearing a sword 哈爾濱工業(yè)大學(xué)本科畢業(yè)設(shè)計(jì)（論文） 3 目 錄 摘 要 ..............................................................................................................................................1 Abstract ..................................................................................................... 2 第一章 緒 論 ............................................................................................. 6 ........................................................ 6 國內(nèi)外發(fā)展現(xiàn)狀 ............................................................................ 6 第二章 整體方案設(shè)計(jì) ................................................................................. 9 引言 ............................................................................................. 9 設(shè)計(jì)思路 ...................................................................................... 9 打包機(jī)的原理 ...................................................................... 9 穿劍式打包機(jī)的設(shè)計(jì)思路 ................................................... 10 方案選擇 .....................................................................................11 機(jī)械系統(tǒng)設(shè)計(jì) ......................................................................11 控制系統(tǒng)設(shè)計(jì) ..................................................................... 13 本章小結(jié) .................................................................................... 13 第三章 機(jī)械系統(tǒng)設(shè)計(jì) ............................................................................... 14 整體設(shè)計(jì) .................................................................................... 14 送退帶機(jī)構(gòu)各零部件的設(shè) 計(jì) ........................................................ 14 捆扎機(jī)架的設(shè)計(jì) ................................................................. 14 傳動(dòng)軸的設(shè)計(jì) .................................................................... 15 滾動(dòng)軸承的選用 ................................................................. 15 傳動(dòng)齒輪的設(shè)計(jì) ................................................................. 15 摩擦輪的設(shè)計(jì) .................................................................... 15 滾珠絲杠的選型計(jì)算 ........................................................... 15 哈爾濱工業(yè)大學(xué)本科畢業(yè)設(shè)計(jì)（論文） 4 ....................................................................... 15 電動(dòng)機(jī)的選擇 .................................................................... 15 捆扎帶材料的選擇 ............................................................. 16 捆扎形式的選擇 ................................................................. 16 捆扎帶接頭形式的選擇 ...................................................... 17 ..................................................................................... 17 Solidworks 簡介 ............................................................... 17 打包機(jī)送退帶機(jī)構(gòu) ............................................................. 18 捆扎粘結(jié)機(jī)構(gòu) .................................................................... 19 本章小結(jié) .................................................................................... 19 第四章 控制系統(tǒng)設(shè)計(jì) ............................................................................... 20 .............................................................................. 20 ....................................................................... 20 步進(jìn)電機(jī)的選擇 .................................................................. 20 步進(jìn)電機(jī)的控制 ................................................................. 21 ........................................................................... 21 氣缸概述 ........................................................................... 22 氣缸型號(hào)的選擇 .................................................................. 22 PLC設(shè)計(jì) ..................................................................................... 22 ................................................................ 24 控制方案設(shè)計(jì) ..................................................................... 24 資源分配表 ......................................................................... 24 PLC 接線圖 ......................................................................... 25 PLC 控制流程圖 .........................................
