熔喷模头温度和压力控制系统的设计

Design of Temperature and Pressure Control System of Meltblown Die

熔喷模头是熔喷布的主要生产设备,由于生产工艺的特殊性,对温度和压力的要求比较严格。为了保证熔喷模头的稳定可靠运行,文章介绍了模头工作原理,设计了一套基于可编程控制器PLC的熔喷模头温度和压力控制系统,以PLC为控制中心构建系统硬件结构,并增加了触摸屏设计。该系统能够实现对模头温度和压力的精确控制,保证整个生产环节的可靠运行。

Melt blown die is the main production equipment for melt blown cloth.Due to the particularity of the production process,the requirements for temperature and pressure are relatively strict.In order to ensure the stable and reliable operation of the meltblown die head,this article introduces the working principle of the die head,and designs a set of temperature and pressure control system for the meltblown die head based on a programmable controller PLC.The system hardware structure is constructed with PLC as the control center.And increase the touch screen design.The system can realize precise control of die temperature and pressure,and ensure the reliable operation of the entire production link.
