Embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Bipatch star quadding machine structure of the present utility model is applicable to that mainly the quad of long-distance symmetric communication cable is stranded as shown in Figure 1; Also can be widely used as the solid or foamed insulation of plastics in the data cable single-core line strand to and various electric wires skein twist: this equipment is by being made up of the permanent tension force active of four-head unwrapping wire 1, guiding trestle 2, quad carriage 3, torque generator 4, star quad stranding main frame 5 five parts.Four single lines are emitted by permanent tension force active unwrapping wire 1, after guiding, enter torque generator 4, every single line all carries out the SZ twisting in torque generator 4, eccentric mean value through conductor in the single line after the SZ twisting is effectively revised, entering star quad stranding main frame 5 at last twists together four single lines, and guarantee four single lines symmetry (being on the top, foursquare four angles) fully from the position of cross section inner wire, in stranded, on stranded cable, twisted wire is fixed with yarn.

The long distance communication signal cable requires the necessary symmetry in four single line positions in the cable, but the single line inner wire is more or less always a bit eccentric, when one or a few single line in four single lines is eccentric, behind the torque generator, to be corrected, its principle as shown in Figure 2.We adopt a motor to be with four rotors to change some circles back another mistake hour hands clockwise simultaneously by two-sided synchronous band in scheme implementation changes some circles, rotation realizes the SZ twisting of every single line so repeatedly, for the symmetry of stranding, four rotors are square profile (as Fig. 3 (a)).Referring to Fig. 3 (b), Fig. 3 (b) is the enlarged diagram of single rotor internal structure; Single line pierces into rotor intermediate shaft hole (41) and goes up around a circle at big guide wheel (44) through a little guide wheel (42) guiding back and (roll on guide wheel and can not produce torque as not enclosing single line around one, it is inhomogeneous that the meeting line ball causes tension force more than two circles) pass from other end axis hole (46) through the little guide wheel of opposite side (45) again, guide wheel broad in the middle (44) needs certain angle, make the single line can line ball in guided wheel slot, referring to Fig. 3 (c), each rotor outside has two stator rings (43) to be prepared for the later process stranding in single line guiding centre hole.

In conjunction with referring to Fig. 4, Fig. 5.Star quad stranding main frame 5 adopts bow formula twisted wire principle, four single lines penetrate from main shaft (51) axis hole, enter the stranded again back of separator (56) through guide wheel (52), carbon fiber strand bow (53), guide wheel (57) through the opposite side spindle hole and by concentric type bundling machine structure yarn is had mercy on and keep twisted wire stable on quad, the good finished product of strand enters that traction wheel (59) draws after guidance set (58), enter take-up reel (511) by winding displacement (510) through guide wheel (54).Main shaft (51), guide wheel (52), carbon fiber strand bow (53) and guide wheel (57) rotate around spindle axis four single lines are twisted together, above structure is identical with traditional twinning machine, but four lines have passed through crooked strand bow (53) in stranded process, guide wheel on the main shaft of both sides (52), (57), make the cross section of twisted wire no longer be square arrangement, that is to say, the traditional double winch can not satisfy its requirement, therefore we have done suitable improvement on the basis of twinning machine, increase cross separator (56) and concentric type and pricked yarn (55), the principle of cross separator (56) such as Fig. 6 (a), Fig. 6 (b), a cross is put in the middle of the twisted wire, four single lines are placed on respectively in four grooves of cross, when the rotating speed of cross with strand bow twisted wire, strand is when identical, the good line of strand bow strand can be opened, simultaneously stranded again again at the opposite side of cross, therefore, the main effect of cross separator (56) is twisted wire to be rearranged make the stable and symmetrical configuration of twisted wire pitch, in design, concentric type is pricked yarn (55) and be placed on cross separator (56) afterwards, make through the stranded again twisted wire of cross separator (56) can effectively not keep twisted wire pitch and Stability Analysis of Structures through directly twining yarn under the situation of any bending.

The traditional relatively twinning machine of star quad stranding main frame of the present utility model improves, it is stranded again to quad to have increased a cross separator means, cross separator inside has individual cross mould to rotate the quad open and close with the twice of strand bow rotating speed, keep original pitch constant, but improved the symmetry of quad; And will under without any the situation of bending, prick the Stability Analysis of Structures that yarn is guaranteed quad immediately through the twisted wire after stranded again.

The foregoing description only is an illustration, can not be used to illustrate scope of the present utility model, as long as equivalent variations of being done on this basis and modification are all within the scope of the invention.
