When conveying in wire rod 19 tension force increase and draw threaded shaft 11 swing certain angle time, angle measuring sensor 12 can be signaled to control system 13, control system 13 can control motor 2 and start, coil 18 on release charging tray 4, alleviate wire rod 19 tension force in conveying, it is prevented that the processed equipment of wire rod 19 is broken; When process equipment stops receiving wire rod 19, motor 2 is rotated further, wire rod 19 tension force reduces until disappearing, after threaded shaft 11 loses the wire rod 19 directed force F to it, the spring 10 that is reset retracts original position, angle measuring sensor 12 is signaled to control system 13 again, and control system 13 controls motor 2 stall, can prevent so again wire rod 19 redundancy from tiing a knot.
As shown in Figure 1 and Figure 2, described stopping means 9 includes rotating the directive wheel 14 being arranged on threaded shaft 11 top, directive wheel 14 is provided with a catch being fixedly connected in threaded shaft 11 15 back to the side of center-pole 5, forms the gap for wire rod traverse between directive wheel 14 and catch 15.
Arranging directive wheel 14 in threaded shaft, to reduce the mill difference power of wire rod 19 and threaded shaft 11, the swing making threaded shaft 11 is sensitiveer, and wire rod 19 also can be avoided to scratch simultaneously.
As shown in Figure 1 and Figure 2, described center-pole 5 being detachably connected with a platen 16, this platen 16 is relative with charging tray 4, it is possible to prevent coil 18 when rotated, and wire rod 19 is deviate from from center-pole 5 top.
As it is shown in figure 1, the upper end of described pin 6 is provided with the bending part 61 upwardly extending and tilting to center-pole 5, so can more easily coil 18 set be installed on pin 6.
As shown in Figure 3, being provided with the fixing nail 17 of a spring on described base plate 7, on described revolution base plate 8, correspondence is also equipped with the fixing nail 17 of a spring and two spring fixing nail 17 mutual dislocation, described back-moving spring 10 is an extension spring, and the two ends of this extension spring connect the fixing nail 17 of a spring respectively.
As shown in Figure 5, described back-moving spring 10 is a torsion spring, this torsion spring set is located in the rotating shaft 20 between base plate 7 and revolution base plate 8, on the fixing nail 17 of spring that one end of torsion spring is connected on revolution base plate 8, the other end is connected on the fixing nail 17 of the spring on base plate 7, in actual production, it is also possible to the two ends of torsion spring are directly fixed on respectively on base plate 7 and revolution base plate 8.
Torsion spring is used to replace extension spring, it is possible to make threaded shaft 11 bidirectional swinging.
Back-moving spring 10 makes threaded shaft 11 can return to original state after losing the active force of wire rod, makes angle measuring sensor be signaled to control system 13, and is controlled motor stalling by control system 13, it is prevented that wire rod is unrestrictedly sent and caused that wire rod is tied a knot.
The work process of the present invention is: as shown in Figure 1, first the coil 18 being rolled into by wire rod 19 or tubing is installed on charging tray, pin is made to be in coil inside, then load onto platen 16 and fix, the head of traction wire rod 19 or tubing is through the gap directive wheel 14 and catch 15 subsequently, and sends into process equipment.
As shown in Fig. 2～Fig. 5, wire rod 19 actively pullled by process equipment, wire rod 19 tension force increases, threaded shaft 11 is created a tensile force f to wire rod 19 direction of advance, under the effect of tensile force f, threaded shaft 11 drives revolution base plate 8 to swing to the direction that wire rod 19 advances gradually, back-moving spring 10 is stretched, pendulum angle is measured and transmits a signal to control system 13 by angle measuring sensor 12, when pendulum angle reaches the initiation value preset, control system 13 starts motor 2, motor 2 drives reductor 3 to rotate, reductor 3 drives the coil 18 on charging tray 4 and charging tray to rotate, coil 18 obtains diastole to the length of wire 19 between process equipment, wire rod 19 tension force reduces, the tensile force f acted in threaded shaft 11 also reduces therewith, threaded shaft 11 is under the pulling force effect of back-moving spring 10, set back gradually, angle measuring sensor 12 is immediately measured angle of oscillation angle value and is transferred to control system 13, when pendulum angle reaches the stop value preset, control system 13 controls motor 2 stall.
Above-mentioned work process is a circulation, in this work process, owing to threaded shaft 11 is capable of swinging, wire rod 19 is made to obtain a buffering when processed equipment is actively pullled, prevent threaded shaft 11 or wire rod 19 from damaging because stress is excessive, angular transducer 12 is utilized immediately to measure the pendulum angle of threaded shaft 11 and motor is controlled, it is to avoid wire rod 19 excessive diastole, it is prevented that wire rod 19 is tied a knot.
After one cycle of operation terminates, can automatically into next cycle of operation, without manual maintenance, it is achieved that feeding can be automatically stopped when process equipment stops receiving wire rod, and can automatically start feeding technique effect when process equipment starts and receives wire rod.
