With the fast development of China's power construction, wires and cables industry has obtained high speed development, and demand persistently increases
Long, cable production is then to be twisted different cable pulling to cage, wrapped to outer surface progress after being twisted, different
Cable considers incomplete during being drawn to cage, has the disadvantages that 1, during cable processing, usually different
The cable of model is placed on bassinet stand conveying, in order to guarantee that the tension between defeated each cable is identical, usually engages band using gear
Each cable reel is moved with the rotation of identical revolving speed and output cable, but in the identical situation of revolving speed, in different cable reels
The remaining length of cable is different, and cable reel retracting diameter it is also different when, the cable length for the cable reel output being relatively large in diameter
Greater than the cable length of the lesser cable reel output of diameter, lead to two kinds of cable stretch differences of output, and two cables are twisting
Detour length is different when conjunction, and the biggish core of tension is stretched, and the lesser core of tension is squeezed, and is in turn resulted in twisted
Cable arches upward and ultimately forms serpentine bend;2, simultaneously during cable twisting, friction causes to reverse between cable outer surface
Angle difference will also result in cable and arch upward and form snake line cable, finally generate scrap wire.

Angular speed reduces after power increases, and then drives rotation linkage disk and cable fixing axle spin down, makes cable reel with constant rotational speed
Rotation, therefore can guarantee that the cable reel output length of two different retracting diameters is consistent, and guarantee the tension of cable output not
The case where becoming, cable twisting avoided to form serpentine bend.
2, pre- twisting structure of the invention is when in use, calmly sliding with the first fixed pulley, second after cable is exported from cable reel
Wheel is closely packed together, and drive the first fixed pulley, the second fixed pulley with two it is different turn to rotation, and the on the first fixed pulley
Two taper gear bands are dynamic to turn round wheel rotation with the second cable, and the first angular wheel on the second fixed pulley drives reciprocating screw, first
Cable, which is turned round wheel and engaged, simultaneously to be rotated, therefore the first angular wheel engage and rotated with reciprocating screw shield is made to drive first fixed to slide
Wheel, the second fixed pulley and cable keep straight line, and the second cable is turned round to take turns to rotate counterclockwise and be rotated clockwise with the first cable torsion wheel
Pre torqued when exporting cable, friction causes windup-degree to be differently formed the case where arching upward during reducing cable twisting, avoids
Finished cable generates snake line, promotes the cable quality of production.

135 left and right ends are closely packed together with slide rail 131, permanent magnet 133 respectively.The pre- twisting structure b4 by shield b41,
First fixed pulley b42, the second fixed pulley b43, reciprocating screw b44, the first angular wheel b45, the second angular wheel b46, first
Cable turns round wheel b47, the second cable turns round wheel b48 composition, and the bottom the shield b41 is through being connected with reciprocating screw b44 and reciprocal
Screw rod b44 upper and lower ends are closely together with regulator shell b11, and the first fixed pulley b42, the second fixed pulley b43 are from upper
It is installed in shield b41 down, the first angular wheel b45 and the second fixed pulley b43 is mutually fastened and and reciprocating screw
B44 engagement, the second angular wheel b46 are mutually fastened with the first fixed pulley b42, and first cable turns round wheel b47, the second electricity
Cable is turned round wheel b48 and is intermeshed respectively with the first angular wheel b45, the second angular wheel b46.The slide rail 131 is equipped with three
It is a and with rotation linkage disk 132 be the center of circle be uniformly distributed in rotation linkage 132 surrounding of disk, tension adjustment can be made more uniform.
Different cables is respectively arranged among cradle frame body 5b, cable passes through the second fixed disk 5c and is sent into cable
It inside sheave 4, and is connect with cable twisting mold, and then cable cradle is driven by the control driving gear-box 3 of control panel 1
Frame 5 rotates.
When in use, by rotating adjusting block 121, and then adjusting block 121 is moved up and down in standing screw 124, works as adjusting
When block 121 moves down, adjusting block 121 pushes rotational speed regulation block 123 to move outward by drive rod 122, adjusts to suitable
Behind position, cable exports and drives cable disc spins, and cable reel passes through cable fixing axle 134 during rotation and drives rotation connection
Moving plate 132 rotates synchronously, and rotates the permanent magnet 133 on linkage disk 132 under the centrifugal force effect that rotation generates along cunning
Dynamic guide rail 131 moves outward, and due to adjusting block 121 with 133 magnetic pole of permanent magnet on the contrary, therefore when drum speed is too fast
When, centrifugal force increase keeps permanent magnet 133 and adjusting block 121 close to each other, and makes the angle of permanent magnet 133 under graviational interaction
Speed reduces, and then drives the revolving speed of rotation linkage disk 132 and cable fixing axle 134 to reduce, while two differences can be made straight
The cable reel of diameter keeps rotating and exporting the cable of equal length with different rotating speeds, keeps the tension of cable, avoids snakelike cable
Formation;Simultaneously when cable output, cable and the first fixed pulley b42, the second fixed pulley b43 are abutted and are driven the first fixed pulley
