摘 要
现如今，产品的生产和商品的流通都离不开精美的包装。随着时代的发展，社会的变迁，包装在商品经济中起着至关重要的作用，也引起了买家和商家的重视。
一个产品从设计到加工，批量生产，再到包装，才能流入到市场。以此看出，包装是产品进入市场不可或缺的一个硬性条件，那么包装机就对产品包装起了一个极大的作用，它既能减少人工包装带来的粗陋，又可以提高包装工作的效率，改进包装的速度和质量，从而使得产品既美观又耐用。总体说来，包装机就是一种对产品进行包装的工作的机械。从1970年开始，我国的包装机械行业就已经开始萌芽了，到了1990年，包装机行业发展十分迅猛，无论是产量，还是种类上，都取得了相当可观的成就。就现在而言，包装机产品在中国市场发展得势头大好，仍有许多潜能等待激发。包装行业也一并成为中国机械行业龙头之一。同时，我们国家对包装机械而言，即是消费大国，亦是生产大国。
     定量包装机传统上一般会根据重力大小进行落料，但是这种落料方式对像处理面粉，水泥，油等粘性比较大，比较难控制流的物料有较大的困难。本课题研究考虑到在保证了螺旋给料定量包装机包装物料准确度的前提下，提出一些可以改进包装机效率的一些方案，可以进一步实现更精确的精度，完善包装的质量。螺旋给料定量包装机的研制不仅提高了工人的劳动效率，而且又可以为企业带来高额的利润。

Design of an auger-type constant weight packing machine
Abstract
The production and circulation of the increasing modernization, mechanical product has been in the rapid development. An important position in the market of commodity exchange also becomes more and more outstanding and has cause wide attention.
It is vital of packing to provide a good environment for products to enter the circulation area. In brief, the packing machine is the machine that packs up the product and also plays a safeguard role of the beautiful appearance. Mechanical enterprise started in china in 1970,and it got the strong development in 1990.What is more, achieved large success not only in the output but also in the quality of products. At present, packing machine has been one of ten big professions in the mechanical industry.
Packing machine is generally taking the traditional gravity blanking method. This way has many difficulties in dealing with the poor liquidity, high viscosity materials such as cement,    sugars. Moreover, this way cannot ensure the measurement accuracy. This study considers the application of the product to meet the packaging requirements, promotes the quantitative packaging machine to improve the accuracy of packaging and the quality of the products’ appearance. Design of design of an auger-type constant weight packing machine not only improves the labor efficiency and obtains high profits for the companies, but also leaves a vital meaning to enhance the power of the automation in the mechanical field.
