Description

Technical Field

[0001] This utility model relates to the field of armoring machine technology, specifically to a multi-directional pressing assembly for an armoring machine. Background Technology

[0002] An armoring machine is a piece of equipment used for processing cables, optical cables, and other wires. Its main function is to tightly wrap metal strips, such as steel or aluminum strips, around the outer layer of the cable to form a metal armor layer, thereby enhancing the cable's mechanical strength, tensile strength, compressive strength, and corrosion resistance. Existing armoring machines use a rotating frame to drive the metal strips to rotate, directly winding them onto the surface of the cable, as shown in the instruction manual. Figure 5 As shown, the metal strip uses the reaction force generated during winding as the unwinding tension for unwinding, which is a type of driven unwinding.

[0003] However, due to the certain hardness of the metal strip, there is resistance during the unwinding process. When the metal strip is wound, the cable will also be subjected to the tension of the metal strip due to the action and reaction forces. When the two metal strips on the front bottom and the back top pull the cable conveyed to the right, it is easy to cause the cable to bend at the corresponding winding position compared to the sides. Because the cable is not straight enough, the winding is not tight enough, which reduces the mechanical strength, tensile strength, compressive strength and corrosion resistance, which urgently needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-directional crimping assembly for armoring machines, which solves the problem that the passive unwinding of metal strips in existing armoring machines causes tension on the cable, resulting in bending and insufficient winding.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: The multi-directional crimping assembly of the cable armoring machine includes a rotating frame rotatably connected to and sleeved on the outside of the cable. Both the front and back of the rotating frame are rotatably connected to unwinding reels carrying steel strips. A positioning plate, a positioning roller group, and a pressure roller are also rotatably connected to the rotating frame. The unwinding reels, positioning plates, positioning roller groups, and pressure rollers on the front and back of the rotating frame are all arranged rotationally symmetrically about the cable as a central axis. Inside the rotating frame, a limiting sleeve is movably sleeved on the surface of the cable and fixed by a fixing frame. The surface of the limiting sleeve is provided with a through-groove. The steel strip sequentially passes around the positioning plate, through the positioning roller group, around the pressure roller, and through the rotating frame and through the through-groove to wind around the surface of the cable.

[0006] Preferably, the limiting sleeve has two through slots that are rotationally symmetrically arranged on the circumference of the limiting sleeve.

[0007] Preferably, the inner diameter of the limiting sleeve is equal to the overall outer diameter of the cable after it is wrapped with steel strip, and the groove is set tangentially along the inner wall of the limiting sleeve.

[0008] Preferably, there are two sets of fixing brackets, which are respectively fixed on the surfaces of both ends of the limiting sleeve.

[0009] Preferably, the fixing frame comprises two symmetrical upper and lower parts, which are connected by fastening bolts and fastening nuts and respectively fixed to the inner wall of the rotating frame by fixing bolts.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention features a movable limiting sleeve fixed inside a rotating frame and fitted onto the outside of the cable. The inner diameter of the limiting sleeve matches the overall outer diameter of the cable after the steel strip is wound around it. The steel strip passes through the positioning sleeve and wraps around the cable surface. During the rotation of the rotating frame and the limiting sleeve, the limiting sleeve effectively presses the steel strip and the cable together, ensuring that the cable remains straight and unbent while the steel strip is wound around it. This results in a tighter wrapping of the steel strip, improving mechanical strength, tensile strength, compressive strength, and corrosion resistance. This invention solves the problem of insufficient wrapping caused by the tension of the metal strip being pulled on the cable during the passive unwinding of the metal strip in existing armoring machines.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1-4As shown, this utility model provides a technical solution: a multi-directional pressing assembly for a cable armoring machine, including a rotating frame 2 rotatably connected to and sleeved on the outside of the cable 1 on the cable armoring machine. The front and back of the rotating frame 2 are rotatably connected to a unwinding reel 4 with a steel strip 3 wound on it. The rotating frame 2 is also rotatably connected to a positioning plate 5, a positioning roller group 6 and a pressure roller 7. The unwinding reel 4, positioning plate 5, positioning roller group 6 and pressure roller 7 on the front and back of the rotating frame 2 are all arranged in a rotationally symmetrical manner with the cable 1 as the central axis. Inside the rotating frame 2, a limiting sleeve 9 is movably sleeved on the surface of the cable 1 and fixed by a fixing frame 8. There are two sets of fixing frames 8, which are respectively fixed on the surfaces at both ends of the limiting sleeve 9. The fixing frame 8 includes two symmetrical upper and lower parts. The upper and lower parts of the fixing frame 8 are connected by fastening bolts 11 and fastening nuts 12 and are respectively fixed to the inner wall of the rotating frame 2 by fixing bolts 13. The inner diameter of the limiting sleeve 9 is equal to the overall outer diameter of the cable 1 after the steel strip 3 is wrapped around it. The surface of the limiting sleeve 9 is provided with a through groove 10, and the through groove 10 is arranged tangentially along the inner wall of the limiting sleeve 9. There are two through grooves 10 on the limiting sleeve 9, and they are arranged in a rotationally symmetrical manner on the circumference of the limiting sleeve 9. The steel strip 3 passes around the positioning disc 5, passes through the positioning roller group 6, passes around the pressure roller 7, and passes through the rotating frame 2 and the through groove 10 in sequence to be wrapped around the surface of the cable 1.

[0015] Working principle: A limiting sleeve 9 is fixed inside the rotating frame 2 and is movably sleeved on the outside of the cable 1. The inner diameter of the limiting sleeve 9 is adapted to the overall outer diameter of the cable 1 after the steel strip 3 is wound. The steel strip 3 passes through the positioning plate 5, through the positioning roller group 6, through the pressure roller 7, and through the rotating frame 2 and the through groove 10 to wind around the surface of the cable 1. During the rotation of the rotating frame 2 and the limiting sleeve 9 to wind the steel strip 3, the limiting sleeve 9 effectively produces a crimping effect on the steel strip 3 and the cable 1, ensuring that the position of the cable 1 wound with the steel strip 3 remains straight and not bent, thereby making the steel strip 3 tightly wound and improving the mechanical strength, tensile strength, compressive strength and corrosion resistance.
