As shown in fig. 1-4, the invention provides a novel stranding machine, which mainly comprises a main frame, a motor, a transmission device, a main shaft, a cradle frame, a pay-off device, a take-up device and a flywheel disc. The main shaft is a pair of rotating shafts which are oppositely arranged along the same axis and is arranged at two ends of the stranding machine; a main transmission shaft connected with a motor is arranged at the bottom of a main frame of the stranding machine, synchronous belt wheels 41 are arranged at two ends of the main transmission shaft and are connected with main shafts at two ends through belts (the belts are not shown), so that the two main shafts can be driven to synchronously rotate in the same direction; the main shaft comprises an inner shaft and an outer shaft which are coaxially arranged, namely the outer shaft 1 is a hollow rotating shaft, and a rotatable inner shaft 2 and a bearing thereof are also arranged in the main shaft; as shown in fig. 2, in this embodiment, the main shaft at one end of the strander is provided with a reversing device, specifically, the reversing device includes a rotating disc 13 fixed on the outer shaft, a rotating shaft 133 is arranged on the circumference of the rotating disc in an axial direction, and a first intermediate wheel 131 and a second intermediate wheel 132 are respectively fixed at two ends of the rotating shaft, wherein the first intermediate wheel 131 is connected with a first fixed pulley 14 on the outer shaft housing through a belt (the belt is not shown) to form a group of belt transmission; an opening is arranged on the outer shaft, and through the opening, the second intermediate wheel 132 and the second driving wheel 21 fixed on the inner shaft form belt driving (a belt is not shown); thus, when the rotary disk 13 rotates synchronously with the outer shaft, the pulley one 14 connected with the intermediate wheel one 131 through the belt cannot rotate, so the rotation direction of the intermediate wheel one 131 is opposite to the rotation direction of the rotary disk 13, the rotation direction of the intermediate wheel two 132 coaxial with the intermediate wheel one 131 is also opposite to the rotation direction of the rotary disk 13, namely opposite to the rotation direction of the outer shaft 1, the intermediate wheel two 132 is in belt transmission with the pulley two 21 fixed on the inner shaft, the rotation direction of the inner shaft 2 is the same as the rotation direction of the intermediate wheel two 132, so the rotation direction of the inner shaft 2 is opposite to the rotation direction of the outer shaft 1, and therefore, the coaxial reverse rotation effect is realized.

In the embodiment, the end parts of the outer shaft and the inner shaft are connected with the independent flywheel discs 15 and 23, so that the whole stranding machine is provided with four flywheel discs, the outer shaft 1, the inner shaft 2 and the flywheel discs are provided with wire passing wheels, the outer shaft 1 and the inner shaft 2 are provided with hollow holes for passing wires, one end of each flywheel disc is provided with the wire passing wheel, and the other end of each flywheel disc is provided with a corresponding balancing weight; the cradle rack 3 is arranged between the main shafts at the two ends, specifically, the cradle rack 3 is fixed with the inner shafts at the two ends, and the inner shaft 2 at one side provided with the reversing device can be used as a driving end to drive the cradle rack 3 to rotate, so that the inner shaft at the other side is driven to rotate; the transmission shaft with the transmission gear 33 is arranged at the bottom of the cradle frame, and the transmission gear 22 is arranged at the part of the inner shafts at the two sides, which is close to the end part of the cradle frame, so that the inner shafts at the two sides and the transmission shaft at the bottom of the cradle frame also form two groups of belt transmission (a belt is not shown), the torque can be stably transmitted between the inner shafts and the cradle frame, and the inner shafts at the two sides keep synchronous rotation.

Based on the structure, the specific embodiment of the invention is as follows, as the line A shown in figure 1 goes, the strand gathered by the external pay-off device enters the strander from the hollow hole of the left main shaft through the wire wheel, the left main shaft rotates to carry out the first twisting of the strand; then the folded yarn is sent to the right outer shaft along the flywheel disc fixed by the outer shaft and the yarn passing wheel thereof for second twisting; meanwhile, the outer shaft on the right side is conveyed into a hollow hole of the inner shaft through a wire wheel, and the third twisting is carried out through the reverse rotation of the inner shaft; then the folded yarn is sent to a hollow hole of the left inner shaft along a flywheel disc fixed on the inner shaft and rotates along with the left inner shaft to complete the fourth twisting; then the folded yarn is sent to a take-up spool for taking up through a wire guide wheel connected with a reduction gearbox on the cradle frame; in summary, for the whole strand, the main shaft of the strander provided by the invention rotates once, and can simultaneously twist four positions, so that compared with the existing strander, the processing efficiency is improved by one time under the condition of the same rotating speed.
