The specific embodiment
The extruder that is used for nine layer co-extrusion high-isolation film blowing machines shown in Figure 1 is made up of control system, drive system, feeding device, heating and cooling system, transmission system, and said control system is a PLC control system; Form by electric, instrument and executing agency; Control the dragging motor of main and auxiliary machine, control temperature, pressure, flow and the Products Quality of main and auxiliary machine, realize the automatic control of whole unit; The go forward side by side collection and the processing of line data realize closed-loop control; Drive system comprises main motor 1 and decelerator 3, is connected by connector 2 between main motor 1 and the decelerator 3; Feeding device is made up of hopper 4 and feeder 5, and hopper 4 is connected by a materials flow pipe above feeder 5; Heating and cooling system comprises heater 6 and cooling device; Transmission system is made up of machine barrel 7, and twin-screw 8 is set in the machine barrel 7; Described PLC control realizes PID (ratio-integration-differential control) control through analog quantity, carries out communication as host computer and M2 double loop from tuning PID temperature control module and PLC by touch-screen, and all parameters that apply to all are provided with through touch-screen and show.
The mode of heating of said heater adopts resistance heated, electrical induction, thermophore to add pine for a kind of, and heating is controlled to be a kind of in a formula control and the proportion control.
Described twin-screw 8 is from low rate start, is permanent torque conditions after transferring to needed rotating speed then, operates steadily, rotating speed do not fluctuate.
The control of double screw extruder starts the step preface:
(1) energized is transferred to certain temperature to temperature control instrument by technology and is heated, and after temperature has arrived by the time, be incubated 3 hours the material in the barrel is softened, and the temperature of being transferred to technological requirement to temperature control instrument is then controlled;
(2) open main frame will be noted motor when opening main frame size of current; If electric current is excessive; At this moment can not speed be transferred up, check whether the material in the barrel is softened, or whether extruder have fault; After must waiting until normally, speed is transferred to the rotating speed of the required usefulness of goods and is produced;
(3) open subsidiary engine feeding machine, hauling machine, cutting machine.
The system block diagram of extruder shown in Figure 2; Its course of work is: be transferred to PLC to the setting value in the touch-screen through communication line; Current Temperatures on while machine barrel and the die head is sent to temperature control module through thermocouple and handles, and is sent among the PLC by temperature control module again.When temperature value and setting value in PLC, carry out numeric ratio after, if currency is lower than setting value, PLC just sends instruction and makes the inner corresponding thermoelectric device of PLC get the electrician to do, and makes contactor get the electrician to do.Because the energising of the closure of contactor makes the heater energising heat.In heating process, thermocouple constantly is sent to temperature control module to Current Temperatures, and temperature control module also constantly is sent to numerical value among the PLC and carries out numeric ratio.After heating after a while, if current temperature value is higher than setting value, PLC just sends instruction, makes PLC inner relay, contactor dead electricity not work.Because the disconnection of contactor makes the heater outage not heat.To cooling blower is arranged, PLC sends instruction simultaneously and makes the inner corresponding relays of PLC get the electrician to do, make blower fan energising work.Through the blower fan cooling, reduce the Current Temperatures of machine barrel.After barrel zone temperature reached setting value, PLC sent instruction, and the internal relay dead electricity is not worked, and the auxiliary reclay coil losing electricity is not worked.Because auxiliary reclay breaks off, the cooling blower outage is quit work.
The parameter tuning of PID controller is the core content of Control System Design, and it is a size of confirming proportionality coefficient, the time of integration and the derivative time of PID controller according to the characteristic of controlled process.The engineering setting method of PID controller parameter mainly contains aritical ratio method, response curve method and damped method, and three kinds of methods respectively have its characteristics, and its common ground all is through test, according to the engineering experience formula controller parameter is adjusted then.Now general what adopt is the aritical ratio method, and it is following to utilize this method to carry out the step of adjusting of PID controller parameter: (1) at first preselected sampling period of enough lacking lets system works; (2) additional proportion controlling unit only occurs threshold oscillation up to system to the step response of input, writes down at this moment ratio amplification coefficient and threshold oscillation cycle; (3) under certain degree of control, calculate the parameter of PID controller through formula.
The double screw extruder electric control system is carried out communication as host computer and M2 double loop from tuning PID temperature control module and PLC by touch-screen; All parameters that apply to can be provided with and show that touch-screen provides a close friend's man-machine interface to us through touch-screen.
