肠衣自动压缩设备结构设计
摘 要
肠衣自动压缩设备是将圆筒状PVDC膜压缩，代替目前火腿肠片状外包装膜，简化生产工艺，降低工人的劳动强度，提高生产效率，增强市场竞争力。本文侧重其传动系统的设计，理论上能够实现肠衣的自动压缩，现实中还需进行必要的改进。
首先，本文介绍了PVDC膜在肉制品包装产业的发展及应用。由此映射出肠衣自动压缩设备的前景。
其次，本文将介绍肠衣自动压缩设备的电机选择，为了提高生产效率，选择的电机能够实现同时带动四台压缩设备。
再次，本文将重点设计和计算传动设备，通过带轮机构，齿轮机构，链轮机构以实现压缩设备所需要的进给速度。
最后，本文简要叙述了压缩系统部件的尺寸确定，及其理想状态的运动状态。最后的控制系统由于时间关系，已经简化。

Abstract
Casing automatic compression device is cylindrical PVDC film compression, instead of now the current packaging film ham sheet, simplifying the production process, reduce labor intensity, improve production efficiency and enhance market competitiveness.This article focuses on the design of its transmission sy
stem, in theory, enables the automatic compression casings, in reality, need to make the necessary improvements.
First, the article describes the PVDC film in the meat packing industry and application. Thus mapping out the prospect of casing automatic compression equipment.
Secondly, we will introduce the motor casing automatic compression equipment selection, in order to improve production efficiency, choice of motor to drive four simultaneous compression equipment.
Again, this article will focus on good design and calculation of transmission equipment, through the pulley body, gear, sprocket body in order to achieve compression equipment required feed rate.
Finally, a brief description of the size of compression system components to determine its ideal state of motion. Finally, the control system of time, has been simplified.
Key words: PVDC film, Compression equipment, Transmission, Control System
