The control method comprises the following steps: setting a temperature target value A by a touch screen; detecting whether the equipment is operated or not by a controller; if a detection result is negative, entering a heating stopping step; if the detection result is positive, receiving a molding temperature detection signal provided by a temperature sensor probe by the controller and calculating the detection result into an actual temperature value B; comparing the current actual temperature value B with the set temperature target value A by the controller; if the A is equal to the B, entering the heating stopping step; otherwise, further comparing whether the A is greater than the B or not; if so, outputting a heating control signal by the controller and sucking a low-voltage contactor under the heating control signal to heat the multilayered compound equipment of the thermoplastic sheet materials by a heating element; and if not, entering the heating stopping step. According to the control method provided by the invention, the equipment can be automatically heated and the heating temperature can be accurately controlled.
Description
Technical field
The present invention relates to the hot-forming temperature-controlled process of a kind of thermo-plastic planking's MULTILAYER COMPOSITE equipment and device.
Background technology
In the process of producing the thermo-plastic planking, wherein a procedure need to be heated material through pressure roller.During thermo-plastic planking's MULTILAYER COMPOSITE device fabrication product, for the requirement of temperature, be quite crucial, and to require the right and left at heating region be that requirement is consistent, and the heat that needs of everywhere must guarantee to reach the temperature of setting in the course of the work.Heating will obtain required temperature in zones of different like this.But in prior art, heating arrangement only is confined to be heated by heating element, then by the artificial mode that adopts the thermometer thermometric, the time of manual control heating.This mode can't reach the accurate control to temperature, also can't realize that the temperature requirement regional to each reaches consistent.
Summary of the invention
For above-mentioned technical matters, the objective of the invention is the hot-forming temperature-controlled process of thermo-plastic planking's MULTILAYER COMPOSITE equipment and device, the present invention can be heated equipment automatically, and can accurately control heating-up temperature.
The technical scheme solved the problems of the technologies described above is as follows:
The hot-forming temperature-controlled process of thermo-plastic planking's MULTILAYER COMPOSITE equipment comprises the following steps:
Step 1 is A by touch-screen set temperature desired value;
Further, also comprise by touch-screen continuous heating temperature value X is set, the comparative result that described A is greater than B is yes, controller also will carry out the comparison of B<(A-X), if comparative result is yes, controller is routinely exported the control signal of heating, makes heating element carry out continuous heating, until B and A equate the step stopped entering heating.
Further, what described controller carried out B<(A-X) is relatively no, controller also will carry out the comparison of B >=(A-B), if comparative result is yes, controller is intermittently exported the control signal of heating, make heating element enter the intermittent-heating state, until B and A equate the step stopped entering heating.
Further, described X is 5-10 ℃.
Further, in described step 3, when A is greater than B, after controller control heating element is heated equipment, the controller control signal that also output voltage is regulated, make voltage regulator reduce the voltage that is carried in the heating element two ends, and equipment is entered to the state of insulation.
A kind of control device of stating, comprise temperature sensing probe, touch-screen, controller, lv contactor and heating element, temperature sensing probe and touch-screen are electrically connected to the input end of controller respectively, the output terminal of controller is electrically connected to the input end of lv contactor, and the output terminal of lv contactor is electrically connected to heating element.
Further, also comprise a voltage regulator, the input end of this voltage regulator is electrically connected on the output terminal of controller, and the output terminal of voltage regulator is electrically connected to heating element.
Further, described controller is PLC.
Adopted such scheme, when the present invention uses: design temperature desired value on touch-screen, and whether judgment device is moved, when moving, equipment just starts comparison touch-screen design temperature, with the actual temperature that controller calculates, the actual temperature value (numerical value means with B) that temperature objectives value (numerical value means with A), controller calculate.Only have the contactor of controlling heating rod when A is greater than B just to understand adhesive, and can carry out once within each scan period of program, so just can control timely current temperature.The comparison of temperature value in different sheet material is produced, if as this class of honeycomb board absorb heat faster sheet material just need to carry out point control to temperature, the benefit of controlling like this is the evolution of heat faster timely, and the continuous production for sheet material will ensure to some extent like this.When when equipment is the heating period, during heating, temperature is relatively just that A and B directly compare, but B and A-X(X are Temperature numerical) relatively, and the X value is artificial setting, in heating process when B<A-X, heating rod continuous heating, otherwise starting intermittent heating when temperature B >=A-B produces and damages equipment to prevent too fast make temperature rise too high of firing rate, when temperature continues to be raised to while reaching B=A the temperature operation above just carrying out, so just can not descend so that temperature remains on design temperature, and like this can also be after temperature arrives at heating power, on larger circuit, increase voltage regulator, keep temperature in order to reduce voltage, can effectively reduce energy consumption like this, and the impact to electrical network is less.
