摘要
水果套袋机械属于高技术、高智能、高竞争的机电一体化产品，高技术成果都会在套袋机械产品中得到应用。纸袋套袋机械可分为折纸、下纸、药板推送、纸袋打开、纸袋传输、折舌、插舌、压平和打批号等功能。
本设计的主要设计内容为水果压紧机的上料装置设计、药板压紧装置设计。完成的主要工作有：
1.综述了水果压紧机的发展历程，发展现状及发展战略。
2.确定了总体方案、套袋工艺，物料的运动方式采用垂直与水平相结合的方
式，从而缩短了机器的尺寸。
3.设计了纸袋上料机构，利用负压吸盘对纸袋进行分离、输送，吸盘由带轮
机构驱动，上下移动。
4.设计了纸袋展开机构，通过槽轮机构驱动带形带对药板进行定量输送。
5.设计了压紧机构，将药板、说明书装入纸袋内，同时完成纸袋的折叠封合。
本设计充分考虑了机械动力学分析，使机械运行平稳。设计过程参考了各类套袋机械设计的长处，同时借鉴了其它机械的优点完成了水果压紧机的设计。本机器套袋能力为50～120袋/分。
本机总体上具有较高的性价比，具有很强的竞争力和很好的发展前景。

Abstract
Medicines and chemical reagents package machinery belongs to a high technology, the integration of machinery with electronics product, high technology achievement city that high intelligence, height compete for are applied in package machinery product. Paper box package machinery may be that the box opens, paper box transfers, breaks tongue, functions such as inserting tongue, flattening and putting a batch number up mark poison board under paper folding, deducing paper feed.
Main part designing that originally expects that the device designs that , the medicine board dress box device designs that on designing that content is that medicines and chemical reagents is packed in box machine's. Main part being completed works having: (1).Have summed up medicines and chemical reagents packing development of box machine course, present situation and development strategy. (2). Have ascertained the overall plan , package handicraft, the material motion way adopt the perpendicularity comparing with level to look at and appraise the way being tied in wedlock , the dimension having shortened a machine thereby. (3). The organization having designed that paper box fixes material, makes use of the negative pressure acetabulum to carry out separation , transportation on paper box , the acetabulum drives , moves about from cam organization. (4). Expect that organization, conveys by the fact that sheave organization drives jugged as well as carrying out a quantify on medicine board on the board having designed medicine. (5). Organization having designed the dress box, board , specifications put medicine into the paper box inner , the enfoldment accomplishing paper box at the same time seals off the small side door. The operation designing that having considered a mechanical kinetics sufficiently analyses, uses machinery originally is stable. Other machinery merit having designed that process has consulted package machinery design of all kinds strong point, drawing lessons at the same time has accomplished medicines and chemical reagents installing box machine design. The machine package ability is allotted for 50 ~ 120 boxes. This machine has higher nature price ratio as a whole, has very strong competition and the very good development prospect.

第1章绪论
1.1水果套袋机械概述
套袋机械是集机、电、光、声、磁、化、生、美为一体的高技术、高智能、高竞争的产品[1]。发展速度快、更新速度快是它的一大特点。世界上一切高技术成果，都会在套袋机械产品中得到应用[2]。
国外的套袋机械近些年有了新特点，主要有：一是生产高效率；二是资源的高利用率，高度的综合利用和发展循环经济；三是产品高度重视节能，重视降低成本；四是高新技术实用化，提高生产效率，产品上水平、上档次；五是科研成果商品化，使套袋机械产品向知识密集化、技术综合化、产品智能化等方面发展[3]。
美国、日本、德国、意大利是世界上套袋机械四大强国。美国是世界上套袋机械发展历史较长的国家，早已形成了独立完整的套袋机械业体系，其品种和产量均居世界之首[4]。10多年来，美国始终保持着世界套袋机械生产和消费大国的地位。其产品以高、大、精、尖产品居多，机械与计算机紧密结合，实现机电一体化控制新型机械产品[5]，以成型、填充、封口三种机械的增长最快，裹包机械和薄膜套袋机占整个市场份额的15%，厚纸袋封袋套袋机在市场占有率中居第二位。从上世纪90年代初以来，美国套
