Description

The elastic filament unwinding device

The utility model relates to a kind of elastic filament unwinding device, and the elastic filament unwinding device of particularly a kind of addition on twisting machine is in order to becoming elastomeric yarn for it with the yarn looping after the elastic filament unwinding.

At present, many units that weave are all trying to explore to utilize existing twisting machine to produce elastomeric yarn, and owing to do not possess the device that the elastic force wire ring is set and makes its unwinding on the ready-made twisting machine, so only with an easy top that is placed on twisting machine, then the elastic force wire ring is held on the support, again the silk on the elastic force wire ring is drawn and the yarn looping, because elastic force wire ring unwinding automatically, can only lean on the passive silk that moves back to come and the yarn looping, also promptly realize unwinding by elastic filament and yarn self pulling force in the looping process, so just, can not control tension force effectively, make the elastomeric yarn elastic force size after the looping irregular, thereby influence the quality of finished product.

Task of the present utility model is that a kind of elastic filament unwinding device that can make elastic filament at the uniform velocity unwinding on one's own initiative, guarantee uniform tension in order will be provided.

Task of the present utility model is finished like this, a kind of elastic filament unwinding device, and it comprises a column 13, respectively at twisting machine frame two ends; Some support holders 14 are on a column 13; Several yarn bracket 11 are on each support holder 14; Hard work leg 15 is on yarn bracket 11; A pair of carriage 12 is on a column 13; Pair of bearing 7,20 is on a pair of carriage 12; One inside and outside deflector roll 1,18 is on pair of bearing 20,7; One driving and driven sprocket wheel 26,8 is on the roller shaft 30 and outer deflector roll 18 respectively at twisting machine; One driving-chain 9 is on driving and driven sprocket wheel 26,8; Inside and outside sprocket wheel 19,6 is on inside and outside deflector roll 1,18; One driving-chain 5 is on inside and outside sprocket wheel 19,6.

The utility model addition can not only be placed the elastic force wire ring reposefully on twisting machine, and at the uniform velocity unwinding on one's own initiative, can not produce the irregular phenomenon of tension force size.

Below in conjunction with accompanying drawing the utility model is further described below.

Fig. 1 is installed on structure chart on the twisting machine for the utility model.

The top of inside and outside deflector roll 1,18 of the present utility model has a spacer assembly.Spacer assembly comprises square bar 4, one group of division board holder 21 and division board 3, and square bar 4 is solid mutually with carriage 12, and division board holder 21 is fixed on the square bar 4, and every division board 3 is fixed on the corresponding division board holder 21.After elastic force wire ring 2 is held on the inside and outside deflector roll 1,18,, make it be in reel 31 corresponding positions with twisting machine all the time for preventing its off normal or tumble and its retaining is protected in the unwinding process by division board 3.

A column 13 of the present utility model is fixed by frame two ends of its end, lower end and twisting machine respectively.Every pair of support holder 14 apart determining deviations fix with a column 13 symmetrically.Each yarn bracket 11 2 end is fixing with pair of brackets holder 14 respectively.Each leg 15 is fixing with each yarn bracket 11 respectively, the arm that a pair of carriage 12 likeness in form one stretch, and its base portion is by the upper fixed of screw, nut and a column 13.Pair of bearing 7,20 is separately fixed at carriage 12 and stretches position arm end.Two ends of inside and outside deflector roll 1,18 place respectively on the bearing block 20,7.Driving and driven sprocket wheel 26,8 is separately fixed at the roller shaft 30 of twisting machine and an end of outer deflector roll 18.Driving-chain 9 is nested with on it just can drive driven sprocket 8 by it, and then makes outer deflector roll 18 rotations.Inside and outside sprocket wheel 19,6 is separately fixed at an end of inside and outside deflector roll 1,18, in driving during by the sheathed of driving-chain 5 by 18 rotations of outer deflector roll deflector roll 1 in the same way, with the speed rotation.Therefore when elastic force wire ring 2 places on the inside and outside deflector roll 1,18, can realize moving back synchronously and separate.

Even driving and driven sprocket wheel 26,8 of the present utility model, driving-chain 9 and inside and outside sprocket wheel 19,6 and driving-chain 5 are correspondingly changed to the bel-drivenn form, but do not depart from the scope of technique scheme of the present utility model yet.Even in addition the utility model is diverted from one use to another on doubling frame, the coverage in the use field of the technical program of not dissociating too.

The utility model be come like this to cooperate with twisting machine and with yarn looping and produce stretch yarn mutually: the yarn 17 that will be inserted on the yarn ingot 10 on the leg 15 is drawn, and make its successively through line hook 22, the reel 25 of twisting machine, break strip dog 24, position-limiting ear 23 until spindle 29; Again elastic filament 16 is drawn on the elastic force wire ring 2 that is held on the inside and outside deflector roll 1,18, and make its through the approach identical with yarn 17 until spindle 29.Twisting machine is started working, and is driven roller shaft 30 rotations and is driven spindle 29 rotations by belt 27 by power.The drive sprocket 26 that is installed with this moment on the roller shaft 30 is made outer deflector roll 18 rotations by driving-chain 9, make interior deflector roll 1 rotation by the outer sprocket wheel 6 on the outer guide shaft 18 by driving-chain 5, by inside and outside deflector roll 1,18 synchronously, in the same way rotation and the elastic filament 16 of elastic force wire ring 2 is moved back separate, and with the advancing and advance of yarn 17, and in traveling process, be wrapped on the yarn 17.The elastomeric yarn 28 that looping becomes is around again on spindle 29.
