咖啡粉枕式包裝機總體設計及橫封切斷裝置設計
摘 要：隨著包裝工業(yè)的不斷發(fā)展，產(chǎn)品包裝在產(chǎn)品生產(chǎn)、產(chǎn)品開發(fā)和產(chǎn)品銷售過程中所起著越來越重要的作用。
本設計通過分析粒料包裝機的總體設計方案及對橫封切斷裝置的部件原理設計,確定主要裝置(供送、下料、成型、牽引、封切、傳動)之間的相互配合關(guān)系。分析了機構(gòu)、傳動系統(tǒng)、控制系統(tǒng)的設計原理,該設計解決了粒料快速、自動包裝等問題。為實現(xiàn)包裝機的預期功能,對其機械傳動系統(tǒng)進行設計。確定傳動路線,并給出其傳動系統(tǒng)結(jié)構(gòu)簡圖。在分析橫封切斷機構(gòu)功能的基礎上, 研究出一種新型凸輪滑桿式間歇橫封機構(gòu), 其特點是運動中力系處于封閉平衡狀態(tài), 且結(jié)構(gòu)簡單, 加工方便, 易于調(diào)試安裝。根據(jù)多功能枕型包裝機橫封切斷工藝要求， 選用凸輪機構(gòu)實現(xiàn)其橫封軸不等速傳動， 并對此傳動機理進行了運動分析， 推導出了通用計算公式。

Design for Pillow-style Packaging Machine of Coffee and Horizontal Cutting Fixtures
Abstract: As the developing of the packing industry, the technique of product packing has played a great role in the products' production,development and selling.
By analyzing the design schema and design principle of the horizontal cutting fixtures for packaging grainy material was introduced,conformed work in relations of main fixtures(feeding, forming, retractor, sealing,driving) through analysis of packaging machine overall plan .The mechanism, driving system and control system were analyzed. The problems of fast and automatically packaging grainy material was solved with this equipment. Based on the requirements for transmission system of handy needle packing machine , a scheme design for transmission system was completed in order to accomplish the expectant function of the mechanism. The transmission route was determined. The sketch was offered. Based on the requirements for transmission system of horizontal cutting fixtures. It conducts an analys is and comparison of mechanism about intermittent traverse seal, and the focus point is to study mechanism about bring forth new idea of interm- ittent trarerse seal.According to the technology require of cross sealing axle of pillow multi-function packaging machine,the cam is used to realize vary velocity motion,and its kinematic analysis is performed,the general caculating formula is deduced.
Key word: Pillow-style packaging machine; Kinematic analysis; Structural characteristics; Horizontal cutting fixtures
