摘要

本次设计分析了各种封口方式的优缺点，重点对封口机的传动系统进行研究和设计。

热压连续封口机主要由封口机构、供料机构和切断机构组成。原料被安放在料辊上，经过托辊引导到封口机构，由封口机构对原料完成热压封口的工作，最后通过切断装置的切断，使原料分离为完整独立的方便袋个体。热压连续封口机，可以根据选择的原料的具体规格，自动调节制袋速度。一般适合于单机作业。

本文对热压连续封口机的工作原理、结构等做了适当的分析、说明和优化，并且在现有热压封口机的基础上进行一系列的设计，设计出一套可行的方案，同时对封口机各部分装置和机构以及封口机传动系统的参数进行了相关的设计计算，最后使用绘图软件画出方便袋封口机主要的工程图。

ABSTRACT

This paper we need design a continuous convenient bag sealing machine. .this paper has used a similar sealing machine as a reference,and discusses the sealing method for many sealing machine, and distinguish the good sealing method from the various sealing methods, and at last focus on the research and design of the hot sealing mechanism and crank slider mechanism.

Hot continuous sealing machine is mainly composed of a sealing mechanism, a feeding mechanism and a cutting mechanism. Raw materials are placed in the material and, after roller guide to sealing mechanism, by sealing mechanism of raw materials to complete the heat sealing of the work, the cutting device for cutting, separation of raw materials for the complete independence of the convenient bag of individual. This sealing method is relatively mature in technology, it has been widely used in the actual production. Continuous hot pressing sealing machine of this design, according to the specific specifications of raw materials, automatic bag making speed regulation. Generally suitable for single operation.

The of hot continuous sealing machine's working principle, structure and do the appropriate analysis, description and optimization, and in the existing hot sealing machine based on a series of design design a feasible scheme, also to the sealing machine each part of the device and institutions and sealing machine drive system parameters were related to the design calculation. Finally, drawing software to draw a convenient bag sealing machine the main engineering drawings.
