Description
Technical field
The utility model belongs to field of textile machinery, especially combing machine apparatus, is more specifically anti-breaking web device after combing machine power-off.
Background technology
Combing machine has and is separated pressue device and drawing and pressuring device, separation pressue device and drawing and pressuring device are that the DC24V two-bit triplet electromagnetic valve being 338D-O15-02-G77 by a model controls air feed simultaneously and dies.
Be separated pressue device to be made up of 16 separation pressurized cylinders, be separated on pressurized cylinder and roller is housed.Web (pressure of clamping is with being added to the atmospheric pressure of cylinder calmly, adjustable) is clamped with roller acting in conjunction when electromagnetic valve obtains the electric pressurized cylinder air feed roller then on this device that to be separated to 16.When electromagnetic valve power-off, two-bit triplet electromagnetic valve resets naturally, then 16 separation pressurized cylinders and 6 drawing-off pressurized cylinders lose air feed simultaneously, is separated between pressurization roller and roller and loses pressure, effectively can not grip web, moving forward and backward of web can not be controlled.
Due to other reasons, whole the unexpected power-off of equipment, DC24V electromagnetic valve dead electricity, electromagnetic valve resets, separation pressurized cylinder and drawing-off pressurized cylinder lose air feed, apply exert pressure and carry out drawing-off by atmospheric pressure to clamping web owing to being separated roller on pressurized cylinder and drawing-off pressurized cylinder and roller, lose the effect of air pressure to cylinder, between cylinder upper leather roller and roller, lose clamping action.Meanwhile, complete machine dead electricity, frequency converter dead electricity, motor loses the control of frequency converter, and machinery inertial drive motor remains in operation, and machine is by a high speed gradually to low speed until come to a complete stop, about 2 seconds of this intermediate demand, owing to losing air pressure to the clamping action of cylinder roller and roller and inertia to the continuous running of machine, web loses the control of roller and roller, causes the fracture to web.Machine is energized driving again, due to the fracture of web, causes much unnecessary loss, the increase of working strength, raw-material loss, waste of time.
Summary of the invention
The required problem solved of the utility model is: overcome the deficiencies in the prior art, and provides anti-breaking web device after the combing machine power-off that is simple, constantly web of a kind of structure.
In order to reach foregoing invention object, the technical scheme that the utility model adopts is, anti-breaking web device after combing machine power-off, comprise: PLC control unit, be separated pressue device, DC24V power supply and drawing and pressuring device and delay working module, wherein said DC24V power supply gives PLC control unit and delay working module for power supply respectively, it is characterized in that: described delay working module is connected electrically in and is separated between pressue device and PLC control unit; Described delay working module is made up of diode, electric capacity, relay, relay coil, electromagnetic valve coil, resistance, be incorporated between relay coil and electromagnetic valve coil after described resistance and capacitances in series, described diode is two, first diode is connected in the parallel branch of relay coil and resistance, and second diode is connected between the Q contact of PLC control unit and electromagnetic valve coil; Described resistance and the parallel branch of electromagnetic valve coil are connected with relay; Described relay is normally off.
The utility model has: structure is simple, web does not rupture, and operating efficiency increases, and saves material and the advantage of time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is delay working modular circuit schematic diagram of the present utility model.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and the utility model is further elaborated.
Fig. 1-Fig. 2 is preferred embodiment of the present utility model, anti-breaking web device after which show combing machine power-off, comprise: PLC control unit 1, be separated pressue device 2, DC24V power supply 3 and drawing and pressuring device 4 and delay working module 5, wherein said DC24V power supply 3 powers to respectively PLC control unit 1 and delay working module 5, it is characterized in that: described delay working module 5 is connected electrically in and is separated between pressue device 2 and PLC control unit 1; Described delay working module 5 is made up of diode 6, electric capacity 7, relay 8, relay coil 9, electromagnetic valve coil 10, resistance 11, described resistance 11 is incorporated between relay coil 9 and electromagnetic valve coil 10 after connecting with electric capacity 7, described diode 6 is two, first diode is connected in the parallel branch of relay coil 9 and resistance 11, and second diode is connected between the Q contact of PLC control unit 1 and electromagnetic valve coil 10; Described resistance 11 and the parallel branch of electromagnetic valve coil 10 are connected with relay 8; Described relay 8 is normally off.
Operation principle:
When unexpected power-off time, relay is due to dead electricity, and KM1-1, KM1-2 normally-closed contact closes, and electric capacity can by current-limiting resistance to DC24V two-bit triplet electromagnetic valve (being separated the electromagnetic valve of pressurized cylinder and drawing-off pressurized cylinder air feed) power supply.The effect of two diodes is unilateral conductions, does not allow the Q point of electric capacity to Switching Power Supply and PLC to apply voltage, has extended to the power-on time of electromagnetic valve coil with to Q point voltage protection in Switching Power Supply and PLC.
When normally running, DC24V power supply 3 charges for this delay working module 5, within 3-5 RC time cycle (namely, charging completes substantially) just can be charged to the 3-5 second maintaining electromagnetic valve coil 10 electricity consumption, machine is normally driven, when machine unexpected power-off time, this device is solenoid valve (electromagnetic valve can not the iron core action because of the time interval of power-off and power supply) under almost not free spacing case, because delay working module oppositely can not be exerted pressure to the output point of PLC, can not charge to switch reversal of power, therefore this device the operation of a machine time because inertia causes is greater than to the duration of power supply of electromagnetic valve, protect raw material can not break.
In addition because electric capacity is to DC24V two-bit triplet electromagnetic valve (being separated the electromagnetic valve of pressurized cylinder and drawing-off pressurized cylinder air feed) power supply, unexpected power-off, motor loses the control of frequency converter, the inertia caused, machine is also by continuous running, this time, DC24V two-bit triplet electromagnetic valve coil obtained electric owing to there being the charging of electric capacity C, continue as and be separated pressurized cylinder and drawing-off pressurized cylinder air feed use, and duration of power supply is greater than the time because inertia machine runs, so web can not rupture, achieve complete machine power-off and web does not rupture this function.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be treated as protection domain of the present utility model.
