The utility model is that the traction wheel with prior art changes two layers up and down into, do not increase any driving arrangement make its become do not have reverse can store line traction wheel admission machine automatically.As Fig. 2, shown in Figure 3, this line traction wheel admission machine that stores automatically comprises hauling machine 2, directive wheel 9, I-beam wheel 10 and transmission device thereof, on hauling machine 2 main shafts 7, install following two traction wheels, following traction wheel 3 is used key connecting with main shaft 7, rotate with hauling machine 2, last traction wheel 6 is contained on the main shaft 7 by rolling bearing 12 and axle sleeve 15, and the pulling of the steel wire when last traction wheel 6 only is subjected to I-beam wheel 10 spirals could be rotated down.Sleeve between the traction wheel 5 is contained on the main shaft 7 by rolling bearing up and down, sleeve 5 is close to down on the traction wheel 3, and form pair of friction components with it by wearing piece 11, deflecting roller 4 is equipped with in the end of stretching out an arm arm from sleeve 5, compression spring 13 is housed on the upper spindle 7 of last traction wheel 6 and adjusts nut 14, change the normal pressure size that sleeve 5 bears by adjusting nut 14, thereby the torque of adjustment, because friction effect, sleeve 5 has the trend of rotating with following traction wheel 3, it is opposite only to be subjected to direction, and during big therebetween friction, sleeve 5 just might not change or rotate round about.Steel wire 1 by the up winding of dextrorotation, is pressed left-handed up winding through deflecting roller 4 backs on last traction wheel 6 on following traction wheel 3, it is as the same that winding direction can exchange, again through guide wheel 9 rollings on I-beam wheel 10, finish take-up work.

Operation principle of the present utility model is:

1. as shown in Figure 4, suppose that traction wheel 3 does not change down, freely rotate and go up traction wheel 6, at this moment go up from direction A and pull out the steel wire that a segment length is L from last traction wheel 6, and fricton-tight between supposition steel wire and last traction wheel, then go up traction wheel 6 and must rotate, can send the steel wire of equal in length, and to twine the into steel wire of same length L from the other end, and last traction wheel 6 is by sending and twine the into rotating speed rotation of equal length steel wire amount simultaneously, and it stores the steel wire amount and does not give increase and decrease.Because following traction wheel 3 maintains static, so traction wheel 3 can not replenish upward traction wheel 6 storage lines by unwrapping wire down, so, at this moment upwards traction wheel 6 is close can only to allow deflecting roller 4, and upwards traction wheel 6 is close but device structure does not allow deflecting roller 4, and can only axially rotate, and the steel wire amount that traction wheel is respectively emitted L/2 about inciting somebody to action, in this case, the steel wire of traction wheel storage is up and down emitted, supply with I-beam wheel 10 and batch steel wire by deflecting roller 4;

2. I-beam wheel is when normal take-up, following traction wheel 3 twines into one section steel wire with normal hauling speed from the B direction, A end from last traction wheel 6 batches identical steel wire amount by I-beam wheel 10 with same speed simultaneously, at this moment the traction wheel rotating speed is identical up and down, switched in opposite, traction wheel twines into and emits the steel wire of equal quantities separately up and down, and two traction wheels are in a kind of relative balance state, the amount of storage line of traction wheel is constant up and down, and deflecting roller 4 is not done axial rotation;

3. receive when I-beam wheel and expire line, shutdown is rolled off the production line when changing wheel, last traction wheel 6 does not change, following traction wheel 3 rotates with normal hauling speed, following traction wheel 3 from B to drawing in the steel wire that a segment length is L, the other end is then emitted the steel wire of equal length, last traction wheel 6 is not because of then can not be entangled to, at this moment deflecting roller 4 will leave axis, but device structure does not allow deflecting roller 4 to leave axis, because the effect of friction, sleeve 5 and turn to 4 will follow down traction wheel 3 rotations, the rotation of deflecting roller 4 traction wheel 6 that will make progress is entangled to steel wire, at this moment deflecting roller 4 can only be pressed the half speed rotation of traction wheel 3 with equidirectional, enter down the steel wire of traction wheel 3 will be by deflecting roller 4 respectively with the steel wire amount spooling of L/2 on two traction wheels up and down, the traction wheel amount of storage line is all increasing up and down, at this moment is the storage line states;

When the I-beam wheel that will receive full line unload change the sky I-beam wheel after, make the speed of the take-up speed of I-beam wheel 10 greater than following traction wheel 3, at this moment, the steel wire amount that the steel wire amount that following traction wheel 3 twines into and emits twines into and emits less than last traction wheel 6, deflecting roller 4 is also with half rotation of following traction wheel 3 with last traction wheel 6 speed discrepancies, and identical with last traction wheel 6 rotation directions, the steel wire of traction wheel 3 storages is down emitted to last traction wheel 6, at this moment be in the unwrapping wire state;

5. when amount of storage line equals the operate as normal amount, make I-beam wheel 10 take-up speeds equal hauling speed, then get back to poised state again, sleeve 5 does not change, and deflecting roller 4 is not done axial rotation, and amount of storage line is constant.

Adopt this line traction wheel admission machine that stores automatically, make steel wire, can not stop because changing wheel or change, not only improved product quality but also improved production efficiency all the time by hauling speed (specific process speed) operation.This admission machine is specially adapted to than thicker wire and requires take-up in the less Steel Wire Heat Treatment of distorting stress, the coated layer unit.
