[0030] A transverse inner cylinder 9 and a transverse outer cylinder 11, wherein the transverse inner cylinder 9 and the transverse outer cylinder 11 are rotatably connected, and a support 20 and a support 18 are rotatably mounted on the transverse inner cylinder 9 and the transverse outer cylinder 11, respectively, and the lower ends of the support 20 and the support 1 18 are fixed on the machine base 1; a driving assembly 17 for driving the transverse inner cylinder 9 and the transverse outer cylinder 11 to rotate in the same direction is also mounted on the machine base 1;

[0034] In the embodiment of the present invention, through the configuration of the support 20 and the support 1 18, the horizontal inner cylinder 9 and the horizontal outer cylinder 11 can be supported for rotation. The design of the driving assembly 17 ensures that the horizontal inner cylinder 9 and the horizontal outer cylinder 11 can rotate in the same direction, and the planetary gear 48 and the ring gear 46 are meshed.

[0036] The traction cable assembly 16 is also used to pull the secondary line 55 while pulling the main line 54, so that multiple secondary lines 55 are twisted on the main line 54 to form a finished cable 1 53. The difference between the finished cable 1 53 and the finished cable 2 is whether there is a main line 54, which will not be elaborated.

[0037] The structural description of the main pay-off assembly 2 and the main conductor assembly 8 is as follows:

[0038] The main pay-off assembly 2 includes a main frame 3, a main line roller 4, a main roller frame 5 and an L-shaped rod 6. The main frame 3 is installed and fixed on the machine base 1.

[0041] Preferably, the auxiliary pay-off assembly 14 performs one revolution in the circumferential direction and one rotation in the reverse direction at the same time, so as to achieve a better application effect.

[0042] like Figure 1 , Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the support shaft 49 is arranged parallel to the horizontal inner cylinder 9; the auxiliary pay-off assembly 14 includes an auxiliary line roller 43 and an auxiliary roller frame 44, and the auxiliary roller frame 44 is installed and fixed on the support shaft 49 at one end away from the planetary gear 48, and the auxiliary line roller 43 for carrying and outputting the auxiliary line 55 is rotatably installed on the auxiliary roller frame 44.

[0044] It should be noted that the main roller frame 5 and the auxiliary roller frame 44 can adopt a U-shaped structure; the main line roller 4 and the auxiliary line roller 43 can be arranged conventionally, and the structure shown in the figure can be referred to without limitation or elaboration; balls (not shown) are preferably arranged on the inner side of the main guide ring 7 and the auxiliary guide ring 51 to reduce friction and improve the reliability of the guidance.

[0045] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the traction cabling assembly 16 includes an inverted U-shaped frame 28, a translation seat 26 is fixed at the lower end of the inverted U-shaped frame 28, the translation seat 26 is slidably connected to a guide rail 27 fixed on the machine base 1, and a translation telescopic cylinder 25 for driving the translation seat 26 to move along the guide rail 27 is also fixed on the machine base 1. The inverted U-shaped frame 28 can be driven by the translation telescopic cylinder 25 to adjust and move relative to the secondary conductor assembly 15 to improve adaptability.

[0046] An upper traction wheel 30 and a lower traction wheel 29 are respectively provided on the inner side of the inverted U-shaped frame 28, and a wheel axle 39 is fixed in the middle of the upper traction wheel 30 and the lower traction wheel 29, and a wheel frame 40 is rotatably installed at both ends of the wheel axle 39, and a vertical guide rod 41 is slidably provided on the wheel frame 40, and the upper and lower ends of the vertical guide rod 41 are respectively fixedly connected to the top of the inverted U-shaped frame 28 and the translation seat 26, and the wheel frame 40 is also threadedly connected with a screw rod 34, and the upper and lower ends of the screw rod 34 are respectively rotatably connected to the top of the inverted U-shaped frame 28 and the translation seat 26.

[0047] The upper ends of the two screw rods 34 are respectively fixed with pulleys 35, and the two pulleys 35 are connected to each other through a transmission belt 33; the upper end of one of the screw rods 34 is also connected to a second motor 32, and the second motor 32 is also fixedly connected to the top of the inverted U-shaped frame 28 through a motor frame 31. When the second motor 32 drives the screw rod 34 to rotate, the upper traction wheel 30 and the lower traction wheel 29 are synchronously approached or moved away.

[0048] An end gear 38 is also fixed to one end of the wheel axle 39, and a long gear 37 is meshed and connected to one side of the two end gears 38. Fixed plates are rotatably connected to the upper and lower ends of the long gear 37. The two fixed plates are also fixedly connected to the inner wall of the inverted U-shaped frame 28, and a motor 36 that is transmission-connected to the long gear 37 is also fixed to one of the fixed plates.

[0049] Preferably, the axes of the transverse inner cylinder 9 and the telescopic cylinder 45 pass through between the upper traction wheel 30 and the lower traction wheel 29, and the upper traction wheel 30 and the lower traction wheel 29 are provided with an annular groove with an arc-shaped concave middle portion to improve the reliability of limiting and outputting the finished cable 53.

[0051] It should be noted that the end face gear 38 is a specially designed gear whose tooth surface is located on the end face of a cylinder or a disk, rather than the usual side face. That is, the end face gear 38 is a mating gear that forms an axial intersection angle of 90 degrees with the spur gear or the bevel gear. The central axis of the pinion and the end face gear 38 are perpendicular, and the two vertical central axes can be intersecting or offset. Here, the pinion is lengthened to obtain the long gear 37 of the present invention, so as to realize the reliable transmission of the long gear 37 to the two end face gears 38, which will not be elaborated.

[0052] The above embodiment of the present invention provides a wire twisting machine for power cable processing, and its main working principle is as follows:

[0053] 1) With the support of support 20 and support 1 18 and the drive of drive assembly 17, the transverse inner cylinder 9 and the transverse outer cylinder 11 can rotate in the same direction. With the meshing mechanism of planetary gear 48 and ring gear 46, the auxiliary pay-off assembly 14 realizes reverse rotation while revolving, which promotes the tight twisting of a single auxiliary line 55 and the twisting of multiple auxiliary lines 55.

[0054] 2) The secondary conductor assembly 15 provides a stable and reliable guide for the secondary wire 55, ensuring that the wire bundle is neat and orderly during the twisting process. At the same time, the main conductor assembly 8 effectively guides the main wire 54, and passes through the horizontal inner tube 9 and the telescopic tube 45 to combine with the secondary wire 55, laying the foundation for subsequent twisting.

[0055] 3) The adjustable sliding design of the telescopic cylinder 45 can adjust the relative position between the auxiliary conductor assembly 15 and the auxiliary pay-off assembly 14 according to actual needs, which improves flexibility and adaptability. In addition, the adjustment of the position of the inverted U-shaped frame 28 by the translation telescopic cylinder 25 and the adjustment of the traction wheel spacing achieved by the motor 2 32 driving the screw rod 34 both enhance the compatibility and adaptability of the equipment to the molding of different types of cables.

[0056] 4) The traction cable assembly 16 can pull the main line 54 while pulling the auxiliary line 55, ensuring that multiple auxiliary lines 55 can be twisted on the main line 54 to form a finished cable 1 53 or a separate finished cable 2. The motor 36 drives the long gear 37 and the end gear 38 to achieve the synchronous rotation of the upper traction wheel 30 and the lower traction wheel 29, ensuring the reliable transportation of the finished cable regardless of how the spacing between the traction wheels changes.

[0057] In addition, the control of each component can be carried out by using a PLC controller disclosed in the prior art, and the model and circuit connection of each component are not specifically limited and can be flexibly set in actual application.

[0058] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
