Foaming Machine Control System Research And Design

Foaming machine is the use of plastic particles as foam packaging materials, theprecision instrument, electronic products, handicrafts, flower arrangement and so onclass be afraid, afraid of the shock pressure for the products of the foam packaging.Foaming machine as a kind of mechanical and electrical integration products, inmodern industrial production automation control occupies an important position. Thefoaming machine control system will directly affect the product’s foam multiplestability, which affect the product market competition ability. Foaming machinecontrol system by foam multiple raw material add weight and foaming good after theamount of particle decision, steam pressure and air pressure does not directlyinfluence foam expansion. Therefore, for this kind of foaming machine developed acan keep stable foam multiple control system is a has great practical significancetopic.This paper describes the foaming machine control system research status at homeand abroad, and analyzes the control system control function and demandcharacteristics, and gives the specific design specification, the study of the currentfoaming machine control system in common use all kinds of Controller, after thecomparative analysis and choice of the Programmable Logic Controller(Programmable Logic Controller (hereinafter referred to as PLC))control methodapplied to industrial production foaming machine control system, and the paperfoaming machine control system of the three main parts are the detailed hardware andsoftware circuit design: the first part add raw material stage use the vacuum pump andlevel sensor for packing the control of the stage; The second part of the raw materialsweighing stage, this is the whole system more important part, because mentionedinfluence foam multiple stable is one of the reasons raw material added weight, so inthis part of the use of the high precision instrument weighing shovel and weighingsensor for raw material add weight of accurate control, The third part of the rawmaterial foaming stage the use of the mixer, oscillating motor, high pressure fan,tuning fork level sensor, the temperature sensor, pressure sensor and high temperatureheating tube to foaming phases control, including tuning fork level sensor is the key,use it to accurate measurement of the foaming particle size achieve control of foamphase is complete or not. Foaming machine control system make full use of the modern advanced technology, improve the labor productivity and improve theworking conditions, and reduce the labor intensity of the workers, maintain a stablefoam expansion, to overcome the human unstable factor, and has good applicationprospect.
