基于PLC的砂型3D打印供墨控制系统设计
Design on Ink Supply Control System for Sand Molding 3D Printing Based on PLC
摘要
Abstract
Due to issues commonly encountered during the printing process of existing sand mold 3D printing equipment,such as ink interruptions,nozzle clogging,and low control precision,a more functionally rational ink supply system is proposed.This system aims to provide continuous,stable,and homogeneous ink to ensure consistent operation of the print head.Based on an analysis of the ink supply system's functional requirements,a sand mold 3D printer ink supply system centered around the Siemens S7-1200 PLC is established,detailing the mechanical structure and the circulation piping.The features of this ink supply system,including constant temperature and pressure,normal printing operations,and ink pressing,are discussed in detail from both hardware and software perspectives.Critical system parameters such as vacuum and temperature are integrated into the display interfaces of the computer and industrial touch screen.The control of ink vacuum and temperature is achieved through the influence of vacuum and ink viscosity on print head operation,with the effectiveness of PID control in adjusting vacuum and temperature being verified.Ultimately,this mechatronic subsystem is constructed and tested,and reliable sand molds are printed in conjunction with other parts of the sand mold printer.The results show that the control system operates stably and effectively fulfills the ink supply function.关键词
