方形纸筒切管机设计论文

学士学位论文 题 目：方形纸筒切管机设计摘 要方形纸管切割属于一个新的课题，目前国尚无类似设备，也未见关于此类设备的论著，本课题讨论的目的在于提供一种操作简便、高效率、高精度、成本低的方形纸筒切管机。本产品可以通过更换仿形凸轮的方式实现对多种规格方形纸管的仿形切割，更换凸轮快速、方便，针对不同规格纸管，使用对应规格的仿形凸轮，使切刀随纸管的转动同步进退，确保切刀对纸管圆周各处切割均匀；该产品具备一副对切刀架，有两把相对的切刀同时对纸管进行切割，可以使纸管的芯轴所受的径向力始终保持平衡而不致于弯曲，切刀的进给与返回采纳气缸作为动力源，动作可靠、灵活。关键词：方形纸管；仿形凸轮；对切刀架；气缸；芯轴AbcstractSquare paper tube cutting belongs to a new problem. At present, there’s no similarity equipment or treatise in our country. The purpose to study this problem is to afford a cheap paper tube machine. It is easy to handle and efficiency and precision.This kind of machine can cut various kinds of paper tube by replace with model cam. And this work is easy and fast. According to the different specifications paper tube, You can use corresponding modeling cam, The paper tube and the knives run in-phase, In order to cut the paper tube to equality. This manufacture have a double knife rest, when the machine works, this pair of knives cut the paper tube at the same time. It can make the axes of paper tube came under balanceable strength, and cann’t be in bend. The power of knives’ advance and backtrack is cylinder, credibility and agility.Key words: Quadrate Paper Tube ； Model Cam ； Double Knife Rest ； Cylinder ；Spindle目 录摘 要 IAbcstractII第 1 章 绪 论 11.1 课题背景 11.1.1 纸制品包装的特点的概述 11.1.2 纸包装的环境性能 21.2 生产现状 21.2.1 切深不均 21.2.2 刀具和芯轴的使用寿命短 31.2.3 芯轴刚度不足 31.2.4 生产效率低下 31.3 解决方案 31.3.1 切深不均的解决方案 31.3.2 刀具进给与返回...
