基于三菱PLC的打印喷头控制系统设计

Design of printing head control system based on Mitsubishi PLC

喷头控制是3D打印系统中的一个重要环节,喷头的控制系统对打印产品的质量起着重要的作用,其中喷头温度的控制、步进电机速度的控制都大大影响着模型成型的好坏。针对3D打印喷头系统的设计应用,设计了基于三菱PLC的3D打印喷头的控制系统。该系统利用三菱AD转换器将温度转换成模拟量实现温度的控制,并且PLC采用晶体管漏型输出,利用特定输出端口发送高速脉冲控制出丝速度。经调试系统可实现温度和进料速度的控制。

Nozzle control is an important part of 3 D printing system.The control system of nozzle plays an important role in the quality of printing products.The temperature control of nozzle and the speed control of stepping motor greatly affect the quality of model forming.Aiming at the design and application of 3 D printing head system,the control system of 3 D printing head based on Mitsubishi PLC is designed.The system uses Mitsubishi AD converter to convert the temperature into analog to realize the temperature control,and the PLC uses transistor leakage output to send high-speed pulse through a specific output port to control the wire speed.The temperature and feeding speed can be controlled by debugging the system.
