摘 要
水溶性塑料薄膜（以下简称水溶膜）是一种新颖的绿色包装材料。它的主要原料是聚乙烯醇及淀粉，能溶于水，降解成无毒无公害的最终产物CO2和H2O。它的应用也较为广泛，在工业、农业及人们日常生活中都有广泛的运用，且随着人们环保意识的不断增强，对水溶膜的需求量也必将持续增长。
本文主要介绍400型水溶膜流研成型系统的设计方法，该系统的主要工作原理是：先将原料在一定条件下制成水溶性胶液，然后将胶液流研到镜面不锈钢带（以下简称钢带）上，用刮刀将胶液均匀刮开，胶液刮层随钢带转动进入烘道烘干，最后剥离成成品膜。烘道的热源来至布置于系统顶部的热供送箱和烘道内置的红外电热管，其内的温度是可控的。刮刀固定于钢带的上部，它可以在一定范围内上下调动，通过控制它与钢带间的缝隙，来达到控制水溶膜厚度的目的。钢带被焊接成环形，安装在一对大滚筒上，位于生产线后端的为主动滚筒，前端的滚筒主要起改向作用，称改向滚筒，刚带传动非常类似于平带传动，但本系统中的钢带既是水溶膜成膜的载体，又是动力转动装置，这一环节的设计十分重要。

ABSTRACT
Water-soluble plastic packaging films (hereinafter referred to water-soluble film) is a new green packaging materials, its main raw material is polyvinyl alcohol and starch, can dissolve in water, degradation of non-toxic pollution-free into the final product of CO2 and H2O. It's also the wider application of the workers, farmers and people in daily life have a wide range of use, and with the enhancement of environmental awareness among the people, the demand for water soluble film will also continue to grow. In this paper, 400 water-soluble film-forming system of research methods, the system's main principle is: first of raw materials under certain conditions, into water-soluble glue, and then glue to flow to the inquiry with stainless steel mirror ( Hereinafter referred to strip), the scraper will Smear
glue evenly, with the strip into the rotation, bake film drying, peeling into the final finished film. Hung Road to the heat source in the system to the layout at the top of the heat and bake for sending me the built-in infrared Electric Road tube, the temperature is controllable. Scraper fixed in the upper strip, it can within a certain range from top to bottom mobilization, through its control of the gap between the strip and to achieve water-soluble film thickness control purposes. Strip was welded into a ring, installed in a large drum, the back-end to take the initiative to drum, drum major from the front of the bend, much like a belt-drive, water-soluble film is a film strip the carrier, is the driving force Moment of devices, this part of the design is very important.
