The wheel surface of first traction wheel group 10, second traction wheel group 12 and third traction wheel group 14 all is equipped with the rubber sleeve, and the rubber sleeve not only possesses fine frictional force with 13 surface contact of steel wire to effectual realization pay-off and the effect of flare-outing can also change along with the change synchronization of 13 diameters of steel wire, guarantee its parcel performance to 13 good steel wire, can also clean the surface of steel wire 13 simultaneously, guarantee the clean degree on 13 surfaces of steel wire.
The following are used specifically: firstly, analyzing the rotating speed of the driving slider 7 driven by the driving disc 4, wherein the rotating angular speed of the driving disc 4 is unchanged during the rotation of the driving disc 4, so that the linear speed of the driving disc 4 at each position is also constant when the distance between the fastening piece 602 and the spindle 3 is constant, but the direction of the linear speed is continuously changed when the fastening piece 602 is located at different positions of the driving disc 4, so that the linear speed is decomposed to the horizontal direction, i.e. the moving speed of the driving slider 7 on the slide rail 2 is also different, as can be known from geometrical relation and physical knowledge, during the feeding process of the driving slider 7 moving along the direction far from the driving disc 4, the moving speed of the driving slider 7 can be summarized as continuously increasing to the maximum value and then continuously decreasing to the minimum value again, the speed of the driving slider 7 at the two end parts is zero, and the speed of the driving slider 7 at the middle part is the maximum value, the maximum value is the product of the angular velocity of the drive disc 4 and the distance of the fastener 602 from the spindle 3.
Therefore, when the device starts to work, the driving disc 4 does not work temporarily, the stepping motor in the first traction wheel set 10 works, the steel wire 13 is fed into the device along the first traction wheel set 10, the stepping motor rotates to drive the steel wire 13 to feed continuously forwards, and sequentially passes through the second traction wheel set 12, the third traction wheel set 14, the driving slider 7 and the driven slider 8 to enter the nail making machine, the stepping motor stops feeding, the driving disc 4 starts to work to drive the driving slider 7 to feed on the slide rail 2, when the driving slider 7 is located at the initial feeding position close to the end of the driving disc 4, the speed of the driving slider 7 is continuously increased from zero, and the driven slider 8 is matched to drive the steel wire 13 to feed to the end of the nail making machine, at the moment, because the rotating speed of the third traction wheel set 14 is zero, and the effective reverse stretching effect can be carried out on the steel wire 13 under the combined action of the rubber sleeve inside, the steel wire 13 in the slide rail 2 is ensured to be in a straightened and tightened state, thereby ensuring that the quality of the steel nail manufactured by the nail making machine meets the requirement.
Through the combined action of the driving slider 7 and the driven slider 8, the moving speed of the whole steel wire 13 should be consistent with the moving speed of the driving slider 7, so when the speed of the driving slider 7 starts to feed from zero, the rotating speed of the end of the first traction wheel set 10 is zero, at this time, because the driving slider 7 is in low-speed slow feeding at this stage, the steel wire 13 at the outer end of the first traction wheel set 10 can slowly enter and be extruded by the first traction wheel set 10, the bending and winding part of the steel wire is corrected, along with the continuous feeding of the steel wire 13, the rotating speed of the stepping motor in the first traction wheel set 10 synchronously starts to increase and is lower than the moving speed of the driving slider 7 on the slide rail 2, and thus the steel wire 13 is subjected to the extruding and reverse stretching effects of the first traction wheel set 10 at the end of the first traction wheel set 10, and the steel wire 13 is continuously corrected and tightened.
Further, the speed of the moving wire 13 is continuously increased before entering the end of the second traction wheel set 12, if the wire 13 is in a reasonable straight state, the pressure value of the wire 13 to the bottom wheel of the second traction wheel set 12 is in a reasonable range, when the wire 13 is knotted before passing through the first traction wheel set 10 and is extruded and corrected by the first traction wheel set 10 after passing through, or the rotation speed of the stepping motor in the first traction wheel set 10 is too high, the length of the wire 13 in the first traction wheel set 10 and the second traction wheel set 12 at the moment is lengthened, so the wire 13 can increase the pressure to the bottom wheel of the second traction wheel set 12, when the pressure value detected by the pressure sensor of the bottom wheel of the second traction wheel set 12 is greater than the set maximum pressure threshold value, the controller in the first traction wheel set 10 can reduce the rotation speed of the stepping motor in the first traction wheel set 10, thereby increasing the reverse straightening hindering effect of the first traction wheel set 10 on the steel wire 13, effectively correcting and straightening the steel wire 13 of the length increasing part, and recovering the straightening state of the steel wire 13; on the contrary, when the too slow hindrance effect to steel wire 13 of first traction wheel set 10 rotational speed was too big, steel wire 13 can be in the transition state of straightening, the pressure of steel wire 13 to second traction wheel set 12 bottom wheel can constantly reduce to the minimum pressure threshold value that establishes this moment, need the controller in first traction wheel set 10 to increase the inside step motor's of first traction wheel set 10 rotational speed this moment, thereby reduce the hindrance effect when first traction wheel set 10 feeds steel wire 13, guarantee that steel wire 13 normally feeds, avoid steel wire 13 too by tensile straightening to lead to the destruction of its performance, reduce the quality of steel nail.
The rotation speed of the third traction sheave assembly 14 is zero, so that when the wire 13 is subjected to the shifting movements of the driving sheave 7 and the driven sheave 8, the reverse stretching blocking effect of the third traction wheel set 14 on the steel wire 13 is constantly changed, the steel wire 13 entering the slide rail 2 is constantly in a stretched and straightened state by virtue of the changing process, the good nail making performance is guaranteed, meanwhile, the rubber sleeves on the outer surfaces of the first traction wheel set 10, the second traction wheel set 12 and the third traction wheel set 14 have good friction effect, the resistance of the rubber sleeves to the steel wire 13 is ensured to be in a reasonable range, meanwhile, the rubber sleeve has good self-deformation capability to adapt to steel wires 13 with various diameters, and can have good wrapping capability, and finally, by means of the cleaning capability of the rubber sleeve, can do simple cleanness to 13 surfaces of steel wire, guarantee can not influence the system nail effect because of the existence of impurity in the system nail in-process.
