Problems solved by technology

[0002] There are mainly three types of control devices for the existing fully automatic injection blow plastic hollow molding machine: one is to use a single-chip microcomputer or embedded chip to design a special control device. The use of this kind of control device exists: it is difficult for field engineers to modify the program, and it must be designed by the designer. The shortcomings of the program modification by the engineers of the special control device manufacturer are not as convenient as using a handheld programmer or a laptop computer to modify the PLC program; secondly, the PLC is used as the control core device, the temperature control instrument is used as the temperature control device, and the LED device is used as the man-machine interface. Engineers use

Abstract

A control of a full-automatic plastic filling and blowing and hollow molding machine of a PLC-high speed singlechip-PIC singlechip includes a PLC- high speed singlechip system which consists of a PLC, a high speed singlechip, a level conversion circuit and a current direction control circuit, a temperature control module which consists of a signal magnifying circuit of a N-path temperature sensor and a driving circuit of a N-path heating device, a hydraulic pressure control system which consists of a PIC singlechip and a driving system of a hydraulic pressure control device, a pneumatic control module and a control panel. The method of using the device of the present invention to automatically control the filling and blowing process of the full-automatic plastic filling and blowing and hollow molding machine includes obtaining the system information, controlling the mechanical motion, controlling the temperature during the process of filling and blowing and controlling a hydraulic pressure flux and constant current of electric current of an electro-liquid proportional valve, and the obtaining of the system information has two routes of a PLC control procedure and a touch-screen interruption disposal. The control has high automatization degree and reliability, friendly human-machine interface, high cost performance of the system and the simple, convenient and practical method.

Description

Technical field: [0001] The present invention relates to a control device and a control method for industrial machinery, in particular to a control device and control for a fully automatic injection-blow plastic hollow molding machine composed of a programmable logic controller (hereinafter referred to as PLC)-high-speed single-chip microcomputer-PIC single-chip microcomputer method. Background technique: [0002] There are mainly three types of control devices for the existing fully automatic injection blow plastic hollow molding machine: one is to use a single-chip microcomputer or embedded chip to design a special control device. The use of this kind of control device exists: it is difficult for field engineers to modify the program, and it must be designed by the designer. The shortcomings of the program modification by the engineers of the special control device manufacturer are not as convenient as using a handheld programmer or a laptop computer to modify the PLC prog...
