In addition, the size of the driving shaft belt wheel 51 is smaller than that of the first take-up pulley belt wheel 101, according to the transmission principle, the angular speed of the take-up pulley 10 rotating along the self axis is smaller than that of the driving shaft 5 rotating along the self axis, that is, smaller than that of the main body support 3 rotating, so that the pulling speed of the take-up pulley 10 on the graphite fiber or the graphite fiber belt can be ensured not to be too high, and the phenomenon that part of the graphite fiber belt is not fully twisted and is pulled to be wound on the take-up pulley 10 to influence the twisting effect is avoided.
Because the space on the take-up pulley 10 is limited, in order to evenly wind the graphite fiber line on the take-up pulley 10, the graphite stranding machine further comprises a strand oscillator 9 arranged between the winding rod 8 and the take-up pulley 10, the strand oscillator 9 is the prior art, as shown in fig. 1 and 2, the strand oscillator 9 comprises a reciprocating screw 95 extending horizontally and installed on the main body support 3, one end of the reciprocating screw 95, which is at the same side with the second take-up pulley 102, protrudes out of the corresponding side wall of the main body support 3, and is provided with a screw pulley 93, the screw pulley 93 is in transmission connection with the second take-up pulley 102 through a transmission belt, and the reciprocating screw 95 rotates immediately when the take-up pulley 10 rotates. Be provided with winding displacement box 91 on the reciprocal screw rod 95, have line hole 94 on the winding displacement box 91, pass line hole 94 through the winding pole 8 winding and through the descending graphite fiber line of winding pole 8 and be collected the winding on take-up pulley 10, at this in-process, winding displacement box 91 moves in the axial of reciprocal screw rod 95 along with the rotation of reciprocal screw rod 95 to twine the graphite fiber line on take-up pulley 10 evenly, with the utilization ratio of fully improving take-up pulley 10. The winding displacement device 9 further comprises a cross rod 92 fixed on the main body support 3, and the winding displacement box 91 is guided and installed on the cross rod 92, so that the movement of the winding displacement box 91 can be guided, and the reciprocating screw 95 of the winding displacement box 91 is prevented from rotating.
In addition, the winding rod 8, the reciprocating screw 95, the take-up pulley 10 and the driving shaft 5 all extend in parallel, so that the space occupied in the main body bracket 3 is reduced, and the structure of the stranding machine is more compact.
Because the main function of the winding rod 8 is to wind and pass the graphite fiber ribbon, and simultaneously twist the graphite fiber ribbon extending from top to bottom to form the graphite fiber ribbon when revolving along with the main body support 3, in order to further facilitate the descending of the graphite fiber ribbon, in the embodiment, the winding rod 8 is also rotatably assembled on the main body support 3 and is in transmission connection with the driving shaft 5, so as to provide the descending pulling force for the graphite fiber ribbon by autorotation while revolving along with the main body support 3, thereby facilitating the descending of the graphite fiber ribbon. Specifically, as shown in fig. 1 and fig. 2, a fixing plate 11 extending vertically is disposed on the side where the second take-up pulley 102 is located and on the side wall of the main body bracket 3, a conversion shaft 12 extending in parallel with the winding rod 8 is rotatably assembled on the fixing plate 11, two ends of the conversion shaft 12 are respectively located on the inner side and the outer side of the side plate where the conversion shaft is located, two ends of the conversion shaft 12 are both provided with conversion shaft pulleys 121, wherein the conversion shaft pulley 121 on the outer side is in transmission connection with the driving shaft pulley 51 on the side where the conversion shaft is located through a transmission belt, and the conversion shaft pulley 121 on the inner side is in transmission connection with the winding rod pulley 81 correspondingly disposed on the winding rod 8. Thus, the winding rod 8 is rotated about its own axis while the driving shaft 5 is rotated about its own axis. Meanwhile, the angular speed of the winding rod 8 during rotation is also smaller than the angular speed of revolution of the main body support 3, so that the graphite fiber belt can be sufficiently twisted under the action of the revolution main body support 3 with a larger speed, and the graphite fiber belt is prevented from being dragged by the winding rod 8 without being sufficiently twisted to cause the graphite fiber belt to go down in advance, and the twisting effect of the graphite fiber belt is influenced.

It should be noted that in the present invention, the graphite fiber ribbon is passed through the upper lead tube 14 at the initial twisting, but as the twisting progresses, the joint point where the graphite fiber ribbon is twisted to form the graphite fiber thread gradually moves upward, so that after a certain period of operation, the graphite fiber ribbon passing through the upper lead tube 14 becomes the graphite fiber thread, and the graphite fiber ribbon exists only above the strander.
When the embodiment of the graphite fiber belt strand making system is used, the material disc 16 is placed above the main body support 3 at intervals through the support, the motor 4 is started, the motor 4 drives the main body support 3 and the driving shaft 5 to synchronously rotate, the graphite fiber belt in the material disc is pulled downwards, two strands are formed through the twisting cone (the structure of the twisting cone can refer to the Chinese utility model patent with the authorization publication number of CN 208955386U), the winding rod 8 in the main body support 3 starts to twist the graphite fiber belt, meanwhile, the driving shaft 5 rotates around the axis of the driving shaft 5 under the meshing transmission with the central shaft 2, the belt wheels of the driving shaft 5 at two sides respectively drive the take-up wheel 10 and the winding rod 8 to rotate, and the take-up wheel 10 drives the reciprocating screw 95 in the strand arranging device 9 to rotate through the transmission relation. Like this, winding rod 8 provides the decurrent pulling force to graphite fiber area or graphite fiber line when twisting to make graphite fiber line down, and evenly twine on take-up pulley 10 through winding displacement ware 9, take-up pulley 10 also provides the downed pulling force for graphite fiber area simultaneously.
Because the material tray 16 is fixed above the strand making machine at intervals and does not rotate along with the main body bracket 3, when the graphite fiber belts in the material tray are about to be used up, the remaining graphite fiber belts are knotted and connected with the graphite fiber belts in the new material tray, and the new material tray is replaced. In the whole process, the main body bracket 3 of the strand making machine does not need to be stopped for waiting, continuous production can be realized, and the twisting efficiency of the graphite fiber belt strand making system is improved.

Therefore, the winding rod provides downward pulling force for the graphite fiber belt while twisting the graphite fiber belt, and the graphite fiber belt is convenient to move downwards. In other embodiments, the winding rod may be fixed to the main body bracket only and is not in driving connection with the driving shaft, so that the winding rod only twists the graphite fiber tape.
