摘要:塑料的发展,大量制造的各种塑料制品,也是促进塑料加工设备不断升级发展的重要原因,塑料加工设备已成为机械工业的重要组成部分,在经济发展中占有很大比重,起了非常关键的作用。塑料成品制品的加工方法在塑料工业中十分常见,在塑料制品的加工于成型中挤出成型是重要方法之一。80856

3D打印技术在生活中已经不是鲜为人知的技术,这种材料成型技术越来越让人熟识,这种材料成型技术是跨世纪的发展和成就。消耗品的发展和浪费也促进了耗材挤出机的发展。塑料是3D打印技术主要的用品,对于3D打印机耗材的处理也成了一个亟待解决的问题,因此对于3D打印机耗材挤出机的研究具有重大意义

挤出加工设备里,塑料耗材挤出机经过了差不多100年的不停改进和改良,从原来开发出来的单螺杆挤出机,又开发出来的双螺杆,多螺杆,甚至无螺丝等方面。塑料耗材挤出机能配合各种塑料成型的其他机器,形成各种塑料加工得制造的流水线,进行对塑料耗材地加工生产。随着塑料在现实中的大泛围多方面的使用和人们对塑料产品的质量的严格。因此,塑料挤出机在塑料生产塑造的工艺中有着举足轻重的意义。

整个设计分为四个部分:挤出机温度控制,压力控制,线径控制和转速控制。 国外化学和化工企业CH402温度控制表执行主机温度查验,加热器与冷却电机的启动和停止,实现温度控制; 在螺杆挤出过程中的压力检测进行挤出机压力的控制; 欧勒测控公司DDM-3020直径测量仪器与编码器和牵引主轴检测和控制线径; 控制转速,通过PLC控制部分和牵引电机部分挤压。

本设备通过PLC作为基础,配合检测工具与传感器,加上继电装置,接触器等装置的帮助用来进行挤出机温度、线直径、转速和电机逻辑控制; 最后用触控屏进行人机交互,对于速度和产品的质量进行监控。

Design of Control System for Material Extruder of 3D Printer

ABSTRACT:The development of plastic, a large number of manufacturing all kinds of plastic products, plastic processing equipment is to promote the development of an important reason for the continuous improvement of plastic processing equipment has become an important part of the machinery industry, occupies a large proportion of economic development, as a very critical role The Processing of finished products of plastic products in the plastics industry is very common in the processing of plastic products in the molding process is one of the important methods。

3D printing technology in life is not a little-known technology, this material forming technology more and more familiar, this material molding technology is a cross-century development and achievements。 The development and waste of consumables also contributed to the development of consumables extruders。 Plastic is the main product of 3D printing technology, for the processing of 3D printer supplies has become an urgent problem to be solved, so for the study of 3D printer supplies extruder is of great significance

Extrusion processing equipment, plastic supplies extruder after nearly 100 years of continuous improvement and improvement, has been developed from the original single-screw extruder, but also developed the twin-screw, multi-screw, and even no screws, etc。 The Plastic supplies extrusion function with a variety of plastic molding of other machines, the formation of a variety of plastic processing and manufacturing lines, the production of plastic supplies to the production。 With the use of plastic in the reality of a wide range of various uses and the quality of plastic products on the strict。 Therefore, the plastic extruder in the plastic production process has a significant significance。
