设计简介
火腿肠肠衣自动压缩设备总体设计
摘 要
本次毕业设计主要是针对目前肉类食品加工包装生产线进行技术改进,提高生产线的自动化,降低工人的劳动强度,降低厂家成本,为厂商在食品领域的价格战中争取优势,提高产品的市场竞争力。众所公认,在商业竞争中,物美与价廉始终必须兼顾。若能切实做到这一点,就不难占领市场,立于不败之地。出路之一在于切实实现合理包装与简化包装的辩证统一。根据国内外工作者在食品包装类机械设备领域的研究成果,借鉴他们的成功经验,运用于设计之中。目前国内大多采用片状PVC肠衣,生产线需要多名工人辅助操作。生产成本较高。而直筒状PVC肠衣能够进一步实现自动化,提高生产效率。以下就是在设计过程中参考到的文献,这些文献给与本文很大的参考价值,本文主要查阅有关机械设计和包装设备的文献期刊。

Abstract
The graduation project mainly is for technology to improve the current meat food processing packaging production line, improve the production line automation to reduce labor intensity, reduce factory costs for manufacturers in the food price war, fighting for advantage, improve product market competitionforce. It is recognized that in the commercial competition, must always take into account the poor quality and low cost. If we can effectively do this, it is not difficult to capture the market and become invincible. One way is the dialectical unity of the practical realization of a reasonable packaging and simplified packaging. According to the research of domestic and foreign workers in the field of food packaging machinery and equipment, learn from their successful experiences, and applied to the design. At present, most of the sheet PVC casings, production line requires a number of workers assisted operating. Higher production costs. Straight shape of the PVC casings to further automate and improve production efficiency.The following is the reference to the literature in the design process, these documents give a great reference value of this paper In this paper, access to literature journals on mechanical design and packaging equipment.
