during the use, twist the rope through sending the line module and carry to the stranded to drive each envelope line section of thick bamboo and heart yearn line section of thick bamboo and rotate and export envelope line and heart yearn, turn round the relative back shaft of rope frame through driving motor drive simultaneously and rotate, thereby make envelope line section of thick bamboo axle and heart yearn line section of thick bamboo axle rotate along the opposite direction of twisting rope frame rotation direction under the effect of belt.

In the brake mechanism, the heart yearn of output passes through the second through wires hole in proper order on the heart yearn line section of thick bamboo, third through wires hole and second through wires hole, thereby make the heart yearn be in tensile state (as shown in fig. 16) with the threading end (the outer end of hinge bar promptly) of brake spare when upwards pulling up at the in-process that the heart yearn upwards carried, and then shift between the brake end (the brake block on the inner of hinge bar promptly) and the heart yearn line section of thick bamboo through the brake spare and reduce the friction between the two, the brake intensity of brake spare to a heart yearn line section of thick bamboo has been reduced, make the brake spare only rotate a certain damping effect to a heart yearn line section of thick bamboo.

In the core wire breakage detection mechanism, the core wire output from the brake mechanism passes through the fourth threading hole and is wound on the first lead wire wheel and the second lead wire wheel, and the wire pressing wheel clamps the core wire between the wire pressing wheel and the first lead wire wheel under the action of the third extension spring (as shown in fig. 11), so that the core wire converted from the longitudinal conveying state to the transverse conveying state has the effect of limiting the trigger part to rotate downwards. Then, the core wire output from the core wire breakage detection mechanism is vertically conveyed along the central axis of the covered wire bobbin shaft and is wound on the covered wire.

In the mechanism for detecting the broken wire of the covered wire, each covered wire on the covered wire barrel passes through the thimble on the corresponding limiting part, converges to the middle part upper part of the covered wire barrel and winds the core wire under the rotation of the covered wire barrel shaft, so that the manufacture of a single rope is completed, the limiting part rotates inwards under the pulling of the covered wire, the limiting part is in an elastic deformation state due to the abutting effect of the extension arm on the winding ring, and the position state between the limiting part and the winding ring is as shown in fig. 7.

In the abdicating mechanism, the manufactured single rope is guided to the upper part of the middle position of the first disc by the lead wheel on the lead frame positioned on the lead position, at the moment, the locking part on the locking part enters the clamping groove and pushes against the lead frame (as shown in fig. 20) under the action of the second extension spring, and then a plurality of manufactured single ropes are twisted into a multi-strand twisted rope through the rotation of the twisted rope frame.

The rope twisting machine stops in the using process under the following two conditions:

(1) When the covered wire is disconnected or the covered wire on the covered wire barrel is used up, the pulling effect of the covered wire on the limiting part cannot be continuously maintained, so that the limiting part outwards rotates under the action of the elasticity of the limiting part and the centrifugal effect generated by the rotation of the covered wire barrel shaft until the extension arm abuts against the winding ring again, the elastic deformation state of the limiting part is changed into the loose state at the moment, the position state between the limiting part and the winding ring is shown in figure 8, and then the sensor controls the rope twisting machine (such as stopping, alarming and the like) by sensing the position change of the limiting part after the form change;

(2) When the core wire is disconnected, the movement limitation of the core wire on the trigger piece is removed due to the conveying of the core wire, so that the trigger piece rotates downwards under the action of gravity, and the trigger end of the trigger piece triggers a limit switch positioned on a moving track of the trigger piece to control the rope twisting machine (such as stopping, alarming and the like);

when the rope twisting machine is changed from the operating state to the stopping state, the upward pulling effect of the core wire on the threading end of the brake piece cannot be continuously maintained due to the fact that the core wire stops conveying, and therefore the threading end of the brake piece can reset under the action of the spring and achieve the braking effect of the brake piece on the core wire bobbin through the increase of friction between the brake end and the core wire bobbin (as shown in fig. 17).

When the covered wire on the covered wire bobbin is used up, the locking piece is rotated and is kept away from the lead frame through the handle, so that the locking part is separated from the clamping groove, the locking of the lead frame on the lead position of the twisting rope frame by the locking piece is released, the lead frame can be rotated relative to the twisting rope frame, the lead frame can be moved and switched to the avoiding position (as shown in figure 21) from the lead position of the twisting rope frame, and the blockage caused by the fact that the lead frame replaces the covered wire bobbin is avoided.

The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
