Description

Technical Field

[0001] The utility model relates to the technical field of cable stranding machines, in particular to a tension adjusting structure and a cable stranding machine. Background Technique

[0002] A cable stranding machine, also known as a stranding machine or a bunching machine, is a mechanical device used to manufacture multi-strand cables. It forms a composite cable with certain structure and performance by stranding multiple single wires (such as copper wires, aluminum wires or other metal wires) together. Cable stranding machines play a crucial role in the wire and cable manufacturing industry and are widely used in the production of various cables such as power cables, communication cables, control cables, and data cables.

[0003] However, when the cable stranding machine conveys and winds the cable, since the cable is in a straight state, during winding, due to the straight-line force, the cable is likely to break. At this time, a tensioning wheel is needed to bend and adjust the tension of the straight cable. However, during adjustment, since the cable is in a bent state, the cable itself is easily driven by the winding force and large-area shaking occurs. This situation not only reduces the flexibility of the cable itself but also causes the cable to be pulled and damaged, making it inconvenient to use. Therefore, we have proposed a tension adjusting structure and a cable stranding machine with the function of being easy to use and are urgently in need of development. Summary of the Utility Model

[0004] Aiming at the above existing technical deficiencies, the purpose of the utility model is to provide a tension adjusting structure and a cable stranding machine. However, when the cable stranding machine conveys and winds the cable, since the cable is in a straight state, during winding, due to the straight-line force, the cable is likely to break. At this time, a tensioning wheel is needed to bend and adjust the tension of the straight cable. However, during adjustment, since the cable is in a bent state, the cable itself is easily driven by the winding force and large-area shaking occurs. This situation not only reduces the flexibility of the cable itself but also causes the cable to be pulled and damaged, making it inconvenient to use.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A tension adjusting structure includes an adjusting assembly. The adjusting assembly includes a mounting frame. Both the left and right sides of the top of the mounting frame are connected with fixed boxes. Both the front and rear sides of the fixed boxes are connected with positioning blocks. The outer surface of the positioning blocks is rotatably connected with connecting rods, and the top ends of the connecting rods penetrate to the top of the positioning blocks.

[0006] Preferably, a protective box is connected to the top of the fixed box, and a square box is connected to the top of the protective box.

[0007] Preferably, a motor is threadedly connected to the inner cavity of the protective box, a motor is threadedly connected to the inner cavity of the square box, and a rotating rod is rotatably connected to the inner cavity of the fixed box.

[0009] Preferably, the outer surface of the tensioning seat is slidably connected to the inner cavity of the protective box, and a tensioning wheel is rotatably connected to the inner side of the tensioning seat.

[0010] Preferably, a long rod is rotatably connected to the inner cavity of the protective box, and the left end of the long rod penetrates to the outside of the protective box. The output shaft of the motor and the top of the rotating rod are respectively connected with two meshing first bevel gears.

[0011] Preferably, a round rod is rotatably connected to the top of the fixed box, and two meshing second bevel gears are respectively connected to the outer surface of the round rod and the left end of the long rod.

[0012] Preferably, three synchronous wheels are respectively sleeved on the outer surfaces of the two connecting rods at the rear and the outer surface of the round rod, and the three synchronous wheels are connected by a synchronous belt. Two belt wheels are sleeved on the outer surfaces of the two connecting rods at the front, and the output shaft of the motor is connected to the top of the connecting rod.

[0013] Preferably, a push plate is connected to the outer surface of the connecting rod. A moving rod is rotatably connected to the side of the push plate away from the connecting rod. A plurality of slide rails are connected to the top of the mounting frame. A sliding frame slidably connected to the moving rod is movably connected to the top of the slide rail. A limiting plate is connected to the outer surface of the sliding frame.

[0014] On the other hand, the present application also provides a wire and cable stranding machine with a tension adjusting structure, including a base and a wire and cable stranding machine body. A wire reel is installed on the top of the base. The rear side of the wire reel is connected to the mounting frame. The wire and cable stranding machine body is located at the rear side of the base.

[0015] The beneficial effect of the present application is that through the setting of the adjusting assembly, while adjusting the tension of the wire and cable, it plays a role in limiting the contact with the wire and cable, thereby avoiding the situation that the wire and cable shakes greatly after adjustment, reducing the damage to the flexibility of the wire and cable during winding and tension adjustment, and protecting the surrounding environment and nearby users. Moreover, it improves the working efficiency of the wire and cable during winding and reduces the resistance of the wire and cable during winding, which is convenient for use.

[0031] Embodiment 2

[0032] As Figures 1 to 8As shown, in order to adjust the height of the two tension pulleys 48, the inner side of the tension seat 47 is rotatably connected with the tension pulley 48, the inner cavity of the protective box 43 is rotatably connected with a long rod 49, and the left end of the long rod 49 penetrates to the outside of the protective box 43.

The top end of the fixed box 42 is rotatably connected with a round rod 411. The outer surface of the round rod 411 and the left end of the long rod 49 are respectively connected with two meshing second bevel gears 412.

[0033] Embodiment Three

[0034] As Figures 2 to 8 , in order to prevent the tensioned cable from shaking violently, two belt pulleys 416 are sleeved on the outer surfaces of the two front connecting rods 415. The output shaft of the motor 45 is connected to the top end of the connecting rod 415. A push plate 417 is connected to the outer surface of the connecting rod 415. A moving rod 418 is rotatably connected to the side of the push plate 417 away from the connecting rod 415. A plurality of slide rails 421 are connected to the top of the mounting bracket 41. A sliding frame 419 that is slidably connected to the moving rod 418 is movably connected to the top of the slide rail 421. A limiting plate 420 is connected to the outer surface of the sliding frame 419;

[0035] When adjusting the tension of the cable, the motor 422 and the motor 45 can be started. The motor 422 drives the long rod 49 to rotate, and the long rod 49 drives the first bevel gear 410 to mesh and rotate. At this time, the first bevel gear 410 uses the principle of screw drive to push the two tensioning seats 47 and the tensioning wheel 48 downward.

The connecting rod 415 drives the push plate 417 and the moving rod 418 to rotate and swing in the direction of the cable, and the moving rod 418 pushes the sliding frame 419 and its limiting plate 420 to move in the direction of the cable. At this time, the motor 45 drives the connecting rod 415 on the right side to rotate. One of the connecting rods 415 drives the other connecting rod 415 to rotate together through the pulley 416 and the belt. At this time, the two connecting rods 415 on the right side drive the push plate 417 and the moving rod 418 on the right side to rotate and swing in the direction of the cable, and the moving rod 418 pushes the sliding frame 419 and the limiting plate 420 to move in the direction of the cable, so that the two left and right limiting plates 420 make relative movements. It should be noted that the limiting plate 420 can be made of flexible or shock-absorbing materials. Furthermore, the two limiting plates 420 limit the cable. Note that it does not directly contact the cable. Finally, after the cable is pressed, the situation that the cable shakes is prevented, which is convenient for use;
