Developing And Design On The Electronic-Hydraulic System Of The High Efficiency And Saving Energy Plastic Hollow Shapping Machine

At present, hollow plastic products has been widely used in machinery, electronics, medicine, household appliances, food, daily necessities, automobile and human, widely used to contain mineral water, cola and other soft drinks, including bottles, bottle, cosmetics Bottles, Re Shuiping carcasses, such as children's toys. At the same time, the hollow products have a higher demand.For this reason it is necessary to optimize the duplex bit hollow plasticmolding machine's electronic control system design, hollow-forming machines raise the level of automation to improve production efficiency and product quality, improve the competitiveness of enterprises. Based on the original duplex-blow molding machine on the basis of a programmable logic controller (PLC) of industrial human-machine interface programme, the duplex-blowing electrical control system designed to ensure that the action of the match around, no Interference, hollow products to improve the yield and quality.In this paper, traditional hydraulic hollow plastic molding machines and technical characteristics of theworking process, Changing-frequency with adjusting-speed.technology and the introduction of hydraulic control system, using Changing-frequency with adjusting-speed technology and modern microprocessor technology and the organic integration of hydraulic system, development and design a new generation of highly efficient energy-saving hydraulic duplex frequency of hollow plastic molding machines, to overcome the traditional hydraulic hollow plastic molding machines of high energy consumption problem. In this issue, the main author of a study are as follows:First introduced a hollow plastic molding machines working principle and characteristics, leads to hollow blow forming process. Then, the hydraulic system controlling the programme, to bring D/A converters and the frequency synchronous controller hydraulic system control programme and this programme and the principle of calculation. On this basis, by the visual simulation results, interactive way to adjust parameters to learn how different parameters on the system of in-depth understanding of the action, the PLC control frequency Hydraulic hollow plastic molding machines to the principle discussed, for DVP32ES00R+DVP16XM01N of PLC hardware design is given the overall planning, preparation of a hollow machine motor control procedures, in the programming of actions in the study duplex control in the timing of the realization of the PLC.Changing-frequency with adjusting-speed technology will be the introduction of hollow plastic molding machines and hydraulic control system, blowing large hollow containers for the production of energy-saving rate is as high as 70%. In practice the application of such models that overcome the traditional hydraulic hollow plastic molding machines the problem of high energy consumption, is the new generation of highly efficient energy-saving hollow plastic molding machine. Design of hollow plastic blow molding machines of the hydraulic system and electronic control systems, to resolve their pre-existing duplex-action timing matching, with the design, debug simple intuitive advantages, in order to achieve hollow blower in the control of superiority, And the blower's rapid high-precision tracking control.
