【摘要】：塑料包装肠衣行业作为塑料包装薄膜领域的一个分支,目前有着很大市场,尤其是对香肠加工食品行业有着十分重要的地位和意义。高压缩比,规格化的塑料包装肠衣产品对后期灌肠工序具有很大益处,可以有效地降低生产成本,提高生产效率。本课题研究的主要内容是研制一款基于气压传动和PLC控制的新型自动塑料包装肠衣褶皱机,主要解决香肠灌装工序中人工压缩肠衣、压缩比小、工作效率低、影响自动化程度改进问题。高压缩比、统一规格褶皱管状成品,可取代香肠灌装时人工压缩工序,降低劳动强度,提高生产效率。通过天津市康泰塑料包装有限公司实际生产验证,肠衣褶皱机工作性能稳定,生产自动化程度高。本课题的主要研究成果包括： (1)深入研究了塑料包装肠衣褶皱机的工作原理和结构特点,对整体机各部分结构进行研究和制作。尤其对旋转切刀装置进行了结构研究与设计,详细计算出切刀伸出量和主动轴转动角度间的存在关系,并设计了角度改变辅助件,实现快速规格匹配。通过工业现场试验对整体机进行调试,调整和改进各部分机构的缺陷进而达到预期设计目的。 (2)采用变频控制,保证塑料包装肠衣褶皱机中牵引挤压辊、牵引胶辊组以及旋转褶皱装置间的线速一致性,详细计算出三者之间速比关系。 (3)气压传动系统设计。根据各部分工序要求,本文设计了一套完整的气动系统,并对气动元件进行了有关选型。 (4)设计采用PLC作为控制核心的自动生产系统；设置上位机,实现PLC与上位机的有效通信及良好的人机交互功能,如根据不同规格肠衣生产要求,对应生产参数可在上位机进行快速设置和调整,以满足生产要求。
[Abstract]:As a branch of the plastic packaging film field , the plastic packaging casing industry has a great market , especially for the sausage processing and food industry . The high compression ratio and the normalized plastic packaging casing product have great benefit to the later stage of sausage filling process , so that the production cost can be effectively reduced , and the production efficiency is improved .

The main content of this research is to develop a novel automatic plastic packaging sausage folding machine based on air pressure transmission and PLC control , which mainly solves the problems of manual compression of casings , small compression ratio , low working efficiency and improvement of automation degree in the sausage filling process . The high compression ratio and uniform specification corrugated tubular product can replace manual compression procedures when filling the sausage , reduce the labor intensity and improve the production efficiency . Through the actual production verification of the Tianjin Kangtai Plastic Packaging Co . , Ltd . , the work performance of the sausage casing folding machine is stable and the production automation degree is high .

The main research results of this subject include :

( 1 ) The working principle and structural characteristics of the plastic packaging casing folding machine are studied in depth , and the structure of each part of the whole machine is studied and manufactured . In particular , the structure research and design of the rotary cutter device are carried out , the existence relation between the extension amount of the cutting knife and the rotation angle of the driving shaft is calculated in detail , and the angle changing auxiliary part is designed to realize the quick specification matching .

( 2 ) adopting frequency conversion control to ensure the line speed consistency between the traction pressing roller , the traction rubber roller group and the rotary folding device in the plastic packaging casing folding machine , and calculating the speed ratio relationship among the three components in detail .

( 3 ) Design of pneumatic transmission system . According to the requirements of each working procedure , a complete pneumatic system is designed , and the pneumatic components are selected .

( 4 ) designing the automatic production system using PLC as the control core ;
the upper computer is arranged to realize the effective communication between the PLC and the upper computer and the good human - machine interaction function , such as according to the production requirements of different specifications of the casings , and the corresponding production parameters can be quickly set and adjusted in the upper computer to meet the production requirements .
