Secondary, since PLC controller is also connect with the reverse gas cleaning unit being arranged in weldering cigarette dust catcher filter cylinder, reverse gas cleaning unit includes
Impulse electromagnetic valve for detecting the differential pressure pickup of filter core two sides air pressure and connecting with air blower, can keep filter core in real time
Clean condition, reduce welding downtime, improve production efficiency, saved the maintenance cost of enterprise.
Detailed description of the invention
Fig. 1 is to constitute a kind of structural schematic diagram for welding cigarette dust catcher linkage control device of the utility model.
Specific embodiment
With reference to the accompanying drawing to it is provided by the utility model it is a kind of weld cigarette dust catcher linkage control device structure and
Working principle is described in further detail.
Referring to Fig. 1, for a kind of structural schematic diagram for the linkage control device for welding cigarette dust catcher provided by the utility model.
The structure of the linkage control device of the weldering cigarette dust catcher is constituted mainly by PLC controller 1, the sensing list on welding mechanism is set
Member and the control unit connecting with weldering cigarette dust catcher are constituted, wherein sensing unit is to be arranged on shearing butt welding trigger squeeze 2
CO for tracking the displacement sensor 3 of solder joint or being arranged on two guarantor's welding machines2Baroceptor, control unit include and weldering
The switch electromagnetic valve 5 that the suction ventilator 4 of cigarette dust catcher connects.
Its working principle is that: the sensing unit setting of the linkage control device is on shearing butt welding trigger squeeze 2, for tracking
Signal is passed to PLC controller 1 by displacement sensor 3 after trigger squeeze 2 is fixed by welding position by the position of solder joint,
PLC controller 1 is that the solenoid valve 5 switched to the suction ventilator 4 of control weldering cigarette dust catcher sends enabling signal；When the welding is completed,
Trigger squeeze 2 unclamps, and signal is passed to PLC controller 1 by displacement sensor 3, and PLC controller 1 is to control weldering cigarette dust catcher
The solenoid valve 5 that suction ventilator 4 switchs sends stopping signal, that is, the automatic start-stop of weldering cigarette dust catcher is realized, certainly in production practices
In, it, can also be using 4 start and stop of suction ventilator of normally opened limit switch control weldering cigarette dust catcher to simplify device structure, only needing will be normal
It opens limit switch to be arranged in the control circuit of suction ventilator 4, pressing plate compresses normally opened limit switch closed communicating downwards i.e.
The control circuit of suction ventilator 4；Sensing unit may be the CO being arranged on two guarantor's welding machines as a preferred method,2Air pressure
While sensor, i.e. welding gun are started to work, the starting weldering cigarette dust catcher operation automatically of PLC controller 1.
In the structure of linkage control device for constituting above-mentioned weldering cigarette dust catcher,
--- in order to realize that the filter core 6 of automatic butt welding cigarette dust catcher is cleaned, extend the service life of filter core 6, it is above-mentioned
PLC controller 1 is also connect with the reverse gas cleaning unit being arranged in weldering cigarette dust catcher filter cylinder, and reverse gas cleaning unit includes for examining
The impulse electromagnetic valve surveying the differential pressure pickup 7 of 6 two sides air pressure of filter core and connecting with air blower, air blower connection are right with filter core 6
The purge nozzle answered, i.e. differential pressure pickup 7 can feed back the air pressure of 6 two sides of filter core to PLC controller 1 in real time, be become by windage
Change the behaviour in service for judging filter core 6 indirectly, if pressure difference is greater than the set value, shows that more affect of impurity filters effect in filter core 6
Fruit, at this moment PLC controller 1 sends work order to the impulse electromagnetic valve 9 of control air blower 8, passes through what is be arranged at 6 back side of filter core
Purge nozzle presents blowback surprisingly to filter core 6 and cleans, it is preferable that purge nozzle is also connected to water pipeline, and injection is clear while purging
Clean water, avoids fugitive dust, and sludge collecting tube is arranged in the lower section of filter cylinder, for collecting flue dust sewage, is convenient for sewage treatment；
--- in order to guarantee air draught dust removing effects, above-mentioned PLC controller 1 also with gas concentration that 10 end of welding gun is set
Sensor 11 connects, and weldering cigarette dust catcher is equipped with the frequency converter 12 of control 4 power of suction ventilator connecting with PLC controller 1, that is, passes through
The concentration of 11 real-time monitoring weld fumes of gas concentration sensor controls the automatic adjustment weldering cigarette of frequency converter 12 by PLC controller 1 and inhales
4 operating power of induced-draught electric motor of dirt device guarantees that suction air volume and fume amount are adapted.
