自动上袋机毕业设计摘 要自动上袋机是一种全自动输送档案袋的机械。其中主要结构包括送袋装置、吸袋装置，所述的送袋装置包括链轮链条输送机构、送袋板、 杆件，托带板和链轮，通过电机及其他传动轴带动链轮间歇运动，通过送袋板与杆件之间的摩擦带动档案袋实现档案袋的输送；所述吸袋装置包括液压缸活塞机构实现吸盘的上下往复运动、吸盘和与配气机构相连接的软管，通过凸轮旋转，带动吸盘连杆机构上下往复运动，在确定时间在确定地点吸盘吸住档案袋并在配气装置呼气的同时链轮带动间歇运动的链条到达指定位置和连杆之间通过一定的摩擦力将档案袋输送至下一个工位，因此送袋准确，档案袋不会发生歪斜和下落现象，提高了给袋质量。自动上袋机的设计功能实现的主要机构有通过槽轮实现链条的间歇运动，实现间歇运动的机构很多有槽轮，棘轮，不完全齿轮，针对本次设计具体实际选择了槽轮，认为是最优的，还有实现吸盘的上下往复运动选择了液压缸活塞机构，还有就是配气机构。这三个主要机构是自动上袋机的核心。本文的所有设计工作均切实执行了相关标准。通过本文的计算、校核可以确保所设计的所有部件均符合要求，能够满足多工位包装机的工作需要，可以在实际生产中加以应用。关键词： 送袋系统 吸袋装置 液压缸活塞机构 配气机构 AbstracThe design of the automatic bag machine is a automatic file cover of mechanical transmission.The major structure including the device to send bag, vacuum bag device, described to send bag device including sprocket chain transmission mechanism, bag of plate, bar, zone plate and chain wheel, motor and other transmission shaft drive chain wheel intermittent motion, through a bag of plate and bar to the realization of friction between the drive the file cover file cover transport;Suction bag device including up and down reciprocating motion of CAM connecting rod mechanism to chuck, chuck and hose connected to distribution agencies, through the CAM rotation, drive the sucker rod system up and down reciprocating motion, in determining the time in determining the location file cover sucker is live and exhale in the distribution of chain and sprocket drive intermittent movement to reach the specified location and connecting rod by the friction between the file cover to the next station, so send bag accurately, file cover not happen skewed and falling phenomenon, improve the quality to the bag.Design function realization of the automatic bag machine main institutions, through the groove to achieve chain of intermittent movement, realize a lot of grooved wheel intermittent motion, ratchet, incomplete gear, according to the design chose the sheave, the actual think is the best, and to achieve the up and down reciprocating movement of the chuck chose CAM connecting rod mechanism, and the distribution agencies.The three main mechanism is the core of the automatic bag machine.All design work of this article shall follow the relevant standards.By calculating and checking of this article can ensure that the design of all components conform to the requirements, can meet the needs of the multistep packaging machine work, as well as applications of practical production.Key word: Send bag system Suction bag device CAM connecting rod mechanism目录第1章 绪 论11.1自动上袋机的简介21.2 当前行业的发展现状21.3 本文研究的主要内容及目标3第2章 自动上袋机整体方案设计42.1 自动上袋机电机的选型42.2 自动上袋机联轴器的选型42.3 自动上袋机传动轴的结构参数设计52.4 自动上袋机轴承的选型62.5 自动上袋机的轴承端盖的选型62.6 自动上袋机的系统方案的选择6第3章 送袋装置设计73.1 送袋装置简介73.2 传动轴及与其配合零件的参数设计73.2.1 传动关系参数的确定83.2.2 主轴参数结构设计93.2.3 滚动轴承的选型103.2.4 带传动的计算11 3. 2. 5 键连接设计 123.3 主要零件的校核133.3.1键的校核143.3.2主轴强度校核143.3.3 校核轴(主轴)的疲劳强度153.3.4滚动轴承的校核163.3.5链轮轴的校核173.4送带装置其他传动部分参数设计 183.4.1链轮链条机构设计193.4.2托袋板的设计213.4.3送袋板的设计223.4.4槽轮机构的设计233.5本章小结25第4章 吸袋装置设计254.1 吸袋装置简介264.2 吸袋装置机构设计264.2.1 液压缸的设计274.2.2 吸盘机构设计274.3 本章小结28结论28致谢29参考文献30
