立箱成型装置的结构设计
摘 要
本文首先介绍了立箱成型装置的背景，国内外立箱成型装置发展水平的现状，以及现有的立箱成型装置存在的一些问题。本课题的题目为纸箱立箱成型装置的结构设计。为使设计过程更加简便清楚，故而将立箱成型装置分为主机架、上箱机构、真空吸箱机构、摇臂输箱机构、纸箱成型装置、纸箱前盖折边机构、纸箱导轨、纸箱侧盖折边机构、胶带封底及纸箱后盖折边机构、压实撞杆机构。通过对每个机构的优化设计，最终组装在主机架上，完成对立箱成型装置的总体结构设计。
各个机构的设计内容主要有机构的主要作用，了解所设计机构所要实现的功能；所有零件的设计；气缸、电机、轴承等标准件的选型计算与校核。其中零件的设计包括尺寸与形状的设计，还需考虑每个机构的总体尺寸，避免在最终组装在主机架的过程中发生干涉。
此次设计的主要创新点有上箱机构, 纸箱成型机中立箱成型工艺为纸箱成型工艺的关键步骤，它决定了纸箱成型机的生产速度和纸箱成型质量，也是影响纸箱成型机生产能力的主要因素。因此，为满足现代纸箱成型的高速化需求，需设计一款能高速完成最大包装为530*290*370的纸盒立箱成型装置。采用重力下滑机构，上箱机构底板与水平面成30°角，从而可以依靠纸箱与挡板的重力自动完成进给，而无需其他驱动机构。采用气缸驱动取料机构，大大加快了取料速度，提高了生产效率。设计了有四个气缸驱动曲拐组成的纸箱折侧盖机构，避免了上下盖折入时会发生末端上下重叠而无法平整的现象。靠电机带动皮带，依靠皮带的摩擦力驱动纸箱前进。
最后对齿轮轴，滚动轴承等重要零部件进行校核。没有问题后将各个机构组装在主机架上，完成立箱成型装置的总体结构设计。并对各个机构进行动画仿真，各个机构均能正常工作，并且在主机架上各个机构之间无干涉现象。从而顺利完成对立箱成型装置的总体结构设计。

Abstract
This paper first introduces the background of the vertical box forming device, the current situation of the development level of the vertical box forming device both at home and abroad, and some problems existing in the existing vertical box forming device. The topic of this topic is the structural design of the carton vertical box forming device. In order to make the design process more simple and clear, the vertical box forming device is divided into main frame, upper box mechanism, vacuum suction box mechanism, rocker arm box mechanism, carton forming device, carton front cover folding mechanism, carton guide, carton side cover folding mechanism, tape seal and carton rear cover folding mechanism, compacted bump mechanism. By optimizing the design of each mechanism, it will finally be assembled on the main frame to complete the overall structure design of the opposite box forming device.
The design contents of each organization mainly have the main function of the organization, understand the function that the design organization should realize, the design of all parts, the calculation and check of the type of cylinder, motor, bearing and so on. The design of parts includes the design of size and shape, and the overall size of each mechanism should be taken into account to avoid interference in the final assembly of the mainframe.
The main innovation of this design is the box mechanism, the carton molding machine neutral box molding process is the key step of the carton molding process. It determines the production speed of carton molding machine and the quality of carton molding, is also the main factor affecting the production capacity of carton molding machine. Therefore, in order to meet the high-speed demand of modern carton molding, we need to design a carton vertical box forming device that can complete the largest package at 530*290*370 at a high speed. With the gravity slide mechanism, the bottom plate of the upper box mechanism is 30 degree angle to the horizontal plane, so that the feed can be automatically completed by the gravitational force of the carton and the baffle, without any other driving mechanism. Adopting cylinder driven reclaimer mechanism greatly speeds up the picking up and improves the production efficiency. A carton folding and side cover mechanism consisting of four cylinders driven crank is designed, which avoids the phenomenon that the upper and lower covers will overlap when the upper and lower covers are folded. The belt is driven by electric motor, and the carton is driven by the friction force of the belt.
Finally, check the important parts such as gear shaft, rolling bearing and so on. After having no problem, the agencies are assembled on the main frame, and the overall structure design of the vertical box forming device is completed. And animated simulation of various agencies, all agencies can work normally, and there is no interference between the agencies on the main frame. So as to successfully complete the overall structure design of the opposed box forming device.
