Operation principle
A, cable core are released
As in figure 2 it is shown, center type wire twisting machine is in operation process, cable core is released under the effect of pull strength on wire spool 14 in the direction of the clock, through I guide wheel 23, II guide wheel 3, III guide wheel 11, then advances forward through spindle hole.Main shaft 12 rotates under the driving of drive system counterclockwise；Wire spool 14 is fixed on main shaft 12 by the 3rd bearing, can be rotated counterclockwise together with main shaft 12 by the effect of friction mechanism 9.Cable core is drawn releases from wire spool 14 so that drum 14 rotates in the direction of the clock relative to main shaft 12.When drum 14 is less than main shaft 12 rotating speed with main shaft 12 rotating Vortex and wire spool 14 rotating speed, cable core is i.e. released smoothly, and now cable core releasing tension force depends on that friction mechanism 9 acts on the size of drum 14 frictional force.When friction mechanism 9 acts on the increase of wire spool 14 frictional force, wire spool 14 diminishes with the speed discrepancy of main shaft 12, then laying tension increases；When friction mechanism 9 acts on the reduction of drum 14 frictional force, drum 14 becomes big with the speed discrepancy of main shaft 12, then laying tension reduces.
B, mechanical tension feedback regulation
As it is shown in figure 1, when twisted cable core is released from draw drum, respectively through I guide wheel 23, II guide wheel 3, III guide wheel 11 under the effect of traction machine pulling force, then through spindle hole until making to rotate stranded at the remittance line mould of wire twisting machine.In cable core traveling process, II wheel bracket 4 is acted on around clockwise moment M2 of bearing pin 16 around anticlockwise moment M1 of bearing pin 16 and compression spring 6 jointly by cable core tension force；Two moment loadings are in opposite direction, wherein moment M2 size can be set by regulation axle 7, M2 is made to be more than M1, and M2 with M1 difference is constant, now II wheel bracket 4 can apply power F to friction mechanism 9 by pressure head 8, make friction plate 9e and put between wire spool 14 compress, now friction plate 9e drive wire spool 14 keep with main shaft 12 constant speed poor together with around main shaft 12 centrage turn round；If M1 is more than M2, between friction plate 9e and draw drum 14, thrust diminishes or is separated between friction plate 9e and draw drum 14.
If the tension force that cable core produces in stranding process is more than setting value, then moment M1 increases, and power F that now pressure head 8 acts on friction mechanism 9 diminishes, and then the frictional force causing friction plate 9e to act on draw drum 14 diminishes, drum 14 becomes big with the speed discrepancy of main shaft 12 so that cable core tension force reduces.The most no longer reduce when laying tension is decreased to setting value, i.e. moment M1 and M2 difference reaches setting value, thus keeps laying tension uniform and stable.
If the tension force that cable core is in stranding process is less than setting value, then moment M1 reduces, and now pressure head 8 acts on the power F change of friction mechanism 9 greatly, and then the frictional force causing friction plate 9e to act on draw drum 14 becomes big, drum 14 diminishes with the speed discrepancy of main shaft 12 so that cable core tension force increases.Be not further added by when laying tension increases to setting value, i.e. moment M1 and M2 difference reaches setting value, thus keeps laying tension uniform and stable.
C, left and right dish switch
Double plate unwrapping wire is as it is shown in figure 1, the most left dish unwrapping wire and right dish unwrapping wire state.When left draw drum unwrapping wire terminates to switch to right dish unwrapping wire, operating handle 5 makes bayonet lock 19 exit from the cotter way of support 10, i.e. released state.Simultaneously II guide wheel 3 and II wheel bracket 4 can together with rotate around bearing pin 16, pressure head 8 friction mechanism 9 is separated from, at this moment runing rest 18 can be made to rotate 180 ° to dextrad, then handle 5 and bayonet lock 19 reset in the opposite side draw-in groove i.e. inserting support 10 under the effect of card pinned torsional spring 20, runing rest 18 is locked, so far completes commutation action.
