稠厚物料灌装机构的毕业设计.docVIP

摘 要 液料物料（简称液料）灌入包装容器的装置叫做灌装机或灌装设备。液料依自重即能灌入包装容器如油、酒、果汁、牛奶、酱油、墨水、糖浆、农药等；也有的需要借助外界压力才能灌入包装容器，如番茄酱、肉糜、牙膏、香脂等。对于低粘度液料，根据是否溶解有二氧化碳气体而分为含气和不含气两类。对于含气液料，习惯上将不含酒精成分的，如汽水，可口可乐、矿泉水等，称为软饮料，而将含有酒精成分的分为如啤酒，汽酒、香槟酒等称为硬饮料。液料包装容器主要有玻璃瓶、金属灌，以及用塑料或柔性复合材料制成的各种杯、管、瓶、袋等。在我国目前仍广泛采用玻璃瓶装各类液料。这是因为，玻璃原料资源丰富、成本低、化学稳定性好、贮存期长，无毒、易清洗，可回收使用，尤其适合包装高档商品。而其主要缺点则是较重、破碎率高、搬运不便。因此，今后宜大力发展轻量瓶及液料软包装。采用铝质二片罐和铝质瓶虽能较好地克服玻璃瓶所在的缺点，但是它制造工艺复杂，成本高，在国内暂时难以迅速推广。至于塑料容器，如聚氯乙烯瓶，因含有毒性的氯乙烯单体，不宜用作食品包装容器，而聚乙烯或聚丙烯容器因其阻气性较差，也不宜灌装含气的和易氧化液料。现今，正致力于研制新型包装材料，如聚酯瓶、共挤复合瓶、复合包装盒等。 采用机械化的灌装方法不仅可以提高劳动生产率，减少产品损失，保证包装质量而且还可减少生产环境和被灌装液料的相互污染。 关键字： ；；Abstract Liquid material (or liquid) device into containers called filling machine and filling equipment. The liquid material according to the weight can be poured into containers such as oil, wine, fruit juice, milk, soy sauce, ink, syrup, pesticide; others need the help of outside pressure can be poured into containers, such as tomato sauce, minced meat, toothpaste, balsam. For low viscosity liquid material, according to whether the dissolved carbon dioxide gas into gas and free gas two. With the gas liquid, habits, non-alcoholic ingredients, such as Coca Cola, soft drinks, mineral water, known as soft drinks, and alcohol component is divided into such as beer, champagne, sparkling wine, called hard drinks. Liquid packaging container glass bottles, metal irrigation, and a variety of cup, made of plastic or flexible composite tubes, bottles, bags etc.. In China is still widely used in glass bottles of various liquid materials. This is because, glass raw materials rich in resources, low cost, good chemical stability, long storage period, non-toxic, easy to clean, recyclable use, especially suitable for luxury goods packaging. But its main drawback is heavy, high crushing rate, inconvenient transportation. Therefore, in the future to develop light weight and liquid soft package. The use of aluminium two cans and aluminum bottle can effectively overcome the shortcomings of glass bott
