Description of drawings
Now the invention will be further described in conjunction with an embodiment and accompanying drawing thereof.
Accompanying drawing 1 is the structure principle chart of temperature control mechanism in the hot-melt flattening binder.
The automatic adjusting parameter of the temperature pid control parameter when accompanying drawing 2 is continuous duty.
The automatic adjusting parameter of the temperature pid control parameter when accompanying drawing 3 is the discontinuous operation state.
The specific embodiment
Referring to accompanying drawing, the temperature control mechanism of hot-melt flattening binder of the present invention mainly is made up of the temperature sensor that is installed in the thermal treatment zone, temperature transmitter, PLC microprocessor and touch-screen.After temperature transmitter converts the non-electrical signal of temperature sensor the signal of telecommunication of standard to, be sent to the analog quantity input of PLC microprocessor again, convert the computing that digital quantity participates in pid control module to by the A/D in the PLC microprocessor, to realize control to the thermal treatment zone.
Concrete hot-melt flattening binder realizes that the method for temperature control is, the mold heated plate of 400mm*800mm is divided into four adds the district, that is: A district heating, the heating of B district, heat in the C district and heat in the D district.Temperature sensor is installed in separately electrical heating district, converts its non-electrical signal the signal of telecommunication of 0～20mA of standard to by temperature transmitter, send the analog quantity input of PLC again to, PLC converts digital quantity to by A/D and participates in computing, control.But, directly influence bonding effect should be with mould that adhesive lining and lining directly contact on temperature, the temperature of the temperature on the mould and our thermal treatment zone must exist difference, respectively A district mould, B district mould, C district mould and D district mould are carried out temperature test with the temperature test instrument, simultaneously test value is compared with the temperature show value in each corresponding district, the difference that will compare is separately proofreaied and correct by temperature deviation and is provided with at last, makes that respectively to distinguish the temperature show value consistent with measured value.Wherein temperature sensor is selected commercially available highly sensitive temperature sensor Pt100 for use, temperature transmitter is selected commercially available SBWZ series RTD temperature transmitter for use, the PLC microprocessor is selected the CP1H type PLC of Japan OMRON for use, this PLC belongs to 32 machines, data operation and disposal ability at a high speed arranged, it has concentrated numerous functions in one, and built-in analog quantity input (A/D) and analog quantity output (D/A) function, reach and carried input of 4 tunnels analogy amounts and the output of 2 passages, especially its A/D and D/A are high-resolution, high response is implemented in for intellectuality is temperature controlled assurance is provided on the hardware.
By the PLC microprocessor duty of bonder is judged in the control of mould, mold work is surpassed 3 minutes and be considered as the service intermittent state at interval, 3 minutes with the interior continous way duty that is considered as.
Owing to have continuous duty and discontinuous operation state, the thermal balance of these two kinds of duties also exists difference, just should take different control datas when temperature is controlled so.CH1H type PLC microprocessor provides band from adjusting PID operational order " PIDAT (19i) ", carry out adjusting certainly under the particular state by this instruction, make by this PIDAT of subroutine call (191), and the data that get of will adjusting certainly preserve, and PID (190) instruction is used when operating in the particular job state.Since adopt centralized Control such as temperature, action, might as well be 500.00==1 (ON) when the service intermittent state; During the continous way duty 500.00==0 (OFF).
Therefore under the different operating state, the process that PID control is handled is as follows:
The automatic adjusting parameter of the temperature pid control parameter by continuous duty the time is referring to accompanying drawing 2.
So, when the PLC microprocessor detected the bonder running status and is in continuous duty, the PLC microprocessor just carried out the control of PID temperature by this parameter of subroutine call, makes temperature be controlled in the desired scope of adhesion technique,
The automatic adjusting parameter of the temperature pid control parameter by the discontinuous operation state time is referring to accompanying drawing 3.
So, when the PLC microprocessor detects the bonder running status and is in the discontinuous operation state, the PLC microprocessor just carries out PID temperature control by this parameter of subroutine call, make temperature control can overshoot, be controlled in the desired scope of adhesion technique.
