Compared with the prior art, the utility model has following advantage: the structure is simplified, and need not to increase in addition the mechanism, can have the mechanism by make full use of, easy operation is convenient, but the auto -manual switches, and the flexibility is very high, the linearity is good, control accuracy is high, and permanent tensile effect is obvious.
Description
Technical field
The utility model relates to a kind of equipment controlled for the passive pay-off constant tension of the needs such as frame type stranding machine, tube-type line strander, cage stranding machine, drum unwrapping wire automatic constant tension control mechanism in the wire twisting machine cage of specifically a kind of cable bare wire.
Background technology
At present, the quality requirements along with power cable is more next high, twists in process processed also more and more higher to the laying tension control overflow of monofilament.Armrest is in the past dynamic regulates mechanical tension, manual regulation Pneumatic Tension, and the automatic tension control etc. in mechanical arm detection dish footpath conventional at present can not meet the demands.
See Fig. 2, the device in existing mechanical arm detection dish footpath is detected by coil diameter detection arm (19), coil diameter and transmits sheet (20), analog quantity proximity switch (21) formed, control by the automatic tension in coil diameter detection arm (19) detection dish footpath the change be difficult to dish footpath and be converted into the controlling quantity of proportional regulator (15) linearly, therefore very low, the identical tension poor effect of poor linearity, control accuracy; And can not human intervention, alerting ability is very poor.To sum up need a kind ofly can manually automatically control to switch, the linearity is better, and the constant-tension control method that precision is higher and device carry out satisfied current this demand.
Summary of the invention
The utility model, for solving existing problem, aims to provide drum unwrapping wire automatic constant tension control mechanism in a kind of wire twisting machine cage.
The technical solution adopted in the utility model comprises thimble cylinder, movable thimble, drum, fixing thimble, tension pulley, left butterfly drg and right butterfly drg, the inner of thimble cylinder promotes movable thimble, and then drum is upwards held out against, and the portable pin on fixing thimble is inserted in the pin-and-hole of drum, thus make tension pulley and drum synchronous axial system.Also comprise analog output module, PLC, digital quantity input module, proportional regulator and apportioning valve; Wherein, analog output module, digital quantity input module are connected with PLC respectively;
Analog output module also connects one end of proportional regulator, and the other end of described proportional regulator connects apportioning valve; Digital quantity input module is also connected with the metering sensor exporting length signals for gathering capstan winch twisted wire;
Wherein, described apportioning valve is provided with the admission port connecting source of the gas, and inner air cavity is also connected left butterfly drg and right butterfly drg by pipeline by described apportioning valve respectively.
Wherein, described PLC is also provided with touch-screen.
Compared to the prior art the utility model has following advantage: 1) designs simplification, and without the need to increasing mechanism in addition; 2) existing mechanism can be made full use of, simple to operation; 3) can switch by automanual, alerting ability is very high; 4) linearity is good, control accuracy is high, the successful of identical tension.

Fig. 1 is the structural representation of drum in wire twisting machine cage.
Fig. 2 is the structural representation of existing constant tension control system.
Fig. 3 is structural representation of the present utility model.
Detailed description of the invention
Now the utility model is further described by reference to the accompanying drawings.
See Fig. 1 and Fig. 3, what Fig. 1, Fig. 3 showed is an embodiment of the present utility model, comprise thimble cylinder 17, movable thimble 18, the drum 2 be arranged on drum frame beam 1, left butterfly drg 3 and right butterfly drg 6, the inner of thimble cylinder 17 promotes movable thimble 18, and then upwards held out against by drum 2, and the portable pin 8 on fixing thimble 7 is made to insert in the pin-and-hole of drum 2; Also comprise analog output module 12, PLC11, digital quantity input module 13, proportional regulator 15 and apportioning valve 16.
Wherein, analog output module 12, digital quantity input module 13 are connected with PLC11 respectively; PLC11 is also provided with touch-screen 10.
Analog output module 12 also connects one end of proportional regulator 15, and the other end of described proportional regulator 15 connects apportioning valve 16; Digital quantity input module 13 is also connected with the metering sensor 14 exporting length signals for gathering capstan winch twisted wire;
Wherein, described apportioning valve 16 is provided with the admission port connecting source of the gas, and inner air cavity is also connected left butterfly drg 3 and right butterfly drg 6 by pipeline by described apportioning valve 16 respectively.
See Fig. 3, promote movable thimble 18 upwards held out against by drum 2 by thimble cylinder 17, and insert in the pin-and-hole of drum 2 by the portable pin 8 on fixing thimble 7, such tension pulley 5 synchronously will rotate together along with drum 2.
Before beginning unwrapping wire, first being set by the touch-screen 10 of unit and input several parameter, when starting unwrapping wire, calculating the brake weight of in real time required tension pulley 5 by PLC11 automatic decision.Touch-screen 10 is also provided with manual automatic transfer switch, can switches at any time.
Along with unwrapping wire starts, PLC11 receives the live signal of metering sensor 14 by digital quantity input module 13, the brake weight of how many lines and tension pulley 5 is also remained in real-time calculating drum, and export to proportional regulator 15 by analog output module 12, atmospheric pressure value corresponding to current brake weight is adjusted to again by proportional regulator 15 control ratio valve 16, and this air pressure is delivered to butterfly drg 6, act on its brake facing 4, brake facing 4 and tension pulley 5 produce a friction drag and are current brake weight.Along with the carrying out of unwrapping wire, dish interior lines amount reduces gradually, and drum coil diameter also reduces gradually, and current brake weight also along with automatically reducing gradually, thus ensures constant tension on copper wire.
Above by reference to the accompanying drawings and embodiment describe embodiment of the present utility model; the structure that embodiment provides does not form restriction of the present utility model; in this area, those skilled in the art can adjust according to needs, make various distortion within the scope of the appended claims or revise all in protection domain.
