Description

Technical Field

[0001] This utility model belongs to the technical field of cable-making equipment, specifically relating to a cable-making machine and its untwisting device. Background Technology

[0002] During the stranding process, the wire will generate torsional stress due to stranding. De-twist is to use a specific mechanical device to rotate the wire in the opposite direction during or after stranding in order to relieve these unnecessary torsional stresses.

[0003] Existing untwisting equipment mainly operates by rotating the reel support during the unwinding process, causing the reel to rotate and unwind simultaneously using oscillation. This operation has a major problem: because the reel support is wound with wire cores, especially large reels, which have a great weight, the rotating reel support needs to be equipped with a high-power motor to meet the requirements, making it extremely inconvenient to operate.

[0004] To address the inconvenience of operating the existing untorsion device and the need for a high-power first motor, the structure of the untorsion device needs to be improved to solve the current technical problem. Utility Model Content

[0005] The purpose of this invention is to provide a cable-forming machine and its untwisting device, which can easily untwise the wire core by rotating the bow instead of the spool support, without the need for a high-power motor, making it convenient, economical and practical.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable-making machine and its untwisting device, comprising two parallel support frames, a spool support, and a spool, wherein the spool is rotatably connected to the spool support, and the spool support is rotatably connected between the two support frames, and the spool is wound with a wire core, characterized in that an arc-shaped bow is rotatably connected between the two support frames, one end of the bow is provided with a rotation drive component, the bow rotates around the spool support, and after the wire core is pulled out from the spool, it first enters from one end of the spool support, then exits from one end of the bow, and movably passes along the concave surface of the bow to the other end of the bow, and finally exits from the bow.

[0007] By adopting the above technical solution, after the wire core is pulled out from the wire spool, it first passes through one end of the wire spool support, then is led out from one end of the bow, and is movably passed through the bow along the concave surface to the other end of the bow, and finally passes out of the bow. During the wire release process, the rotation drive component drives the bow to rotate, and the bow drives the wire core to rotate around the wire spool support and the wire spool, thereby completing the untwisting of the wire core. By rotating the bow instead of rotating the wire spool support, the untwisting of the wire core can be easily completed. The operation is convenient, no high-power motor is required, saving motor costs, while reducing energy consumption and saving energy, making it economical and practical.

[0008] To better realize this utility model, two bows are provided and arranged symmetrically, forming an elliptical structure that rotates around the coil support.

[0009] By adopting the above technical solution and setting two symmetrical drawbars, the rotational balance of the entire device can be improved.

[0010] To better realize this utility model, the rotary drive assembly includes a first motor, a driving pulley, a transmission belt, and a driven pulley. Hollow shafts are fixedly connected to both ends of the bow. One end of the hollow shaft is rotatably connected to the support frame. One of the hollow shafts passes through the support frame and is fixedly connected to the driven pulley. The driven pulley is connected to the driving pulley via the transmission belt. The driving pulley is connected to the output shaft of the first motor.

[0011] By adopting the above technical solution, the hollow shaft is rotated by the drive of the first motor and the pulley transmission structure, thereby driving the drawbone to rotate.

[0012] To better realize this utility model, the coil bracket is rotatably connected to the end of the hollow shaft away from the support frame.

[0013] By adopting the above technical solution, the wire core winding surface is relatively wide, giving the wire reel support a certain swinging ability. This allows for flexible adjustment of the wire core's pull-out position during the wire feeding process, thus preventing damage to the wire core.

[0014] To better realize this utility model, one end of the coil support is provided with a first through hole for the wire core to pass through, and the first through hole passes through the hollow rotating shaft.

[0015] By adopting the above technical solution, the conductor can always pass through the center of rotation, regardless of how the bow rotates, reducing the risk of damage to the conductor caused by swinging friction.

[0016] To better realize this utility model, the hollow rotating shaft is provided with a second through hole at the end away from the support frame for the wire core to pass through.

[0017] By adopting the above technical solution, the wire core is tangentially introduced into the hollow shaft from the fixed pulley, or tangentially introduced from the hollow shaft to the fixed pulley, so that the wire core's movement path is constant and the oscillation wear is reduced.

[0018] To better realize this utility model, the outer edges of the first and second perforations are both rounded.

[0019] By adopting the above technical solution, the rounded corner structure can greatly prevent the wire core from being worn or scratched.

[0020] To better realize this utility model, the bow is rotatably connected to multiple fixed pulleys, and the wire core is in rolling contact with the multiple fixed pulleys.

[0021] By adopting the above technical solution, the sliding contact is improved to rolling contact, which can minimize frictional damage during the wire core unwinding process.

[0022] This utility model further discloses a cable-forming machine, including a plurality of untwisting devices as described in any of the above claims, characterized in that the reel of one of the untwisting devices is connected to a second motor, and the direction of the wire core in the untwisting device is opposite to the direction of the wire core in all other untwisting devices.

[0023] Beneficial effects:

[0024] This invention features a bow that rotates around a spool support between support frames, allowing the wire core to pass through the bow before exiting. Only a small-power motor is needed to drive the bow's rotation, replacing the rotation of the spool support. This easily completes the wire core unwinding process, with the spool only serving to release the wire and the bow acting as a traction mechanism for unwinding. The operation is convenient, requires no high-power motor, saves motor costs, reduces energy consumption, and is economical and practical.

[0025] The cable-forming machine of this utility model consists of multiple sets of untwisting devices. The reel of one of the untwisting devices is connected to a second motor, and the direction of the wire core is opposite to that of the wire core in the other untwisting devices. When multiple wire cores are inserted into the untwisting device, the first motor drives the bow to rotate and the second motor drives the reel to rotate. The multiple wire cores are automatically twisted into a cable during the movement and wound on the reel, which is efficient and convenient. Attached Figure Description

[0032] 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.

[0033] Example

[0034] like Figures 1-4 As shown, a cable-forming machine untwisting device includes two parallel support frames 1, a spool support 2, and a spool 3. The spool 3 is rotatably connected to the spool support 2, and the spool support 2 is rotatably connected between the two support frames 1. The spool 3 is wound with a wire core 4. The device is characterized in that an arc-shaped bow 5 is rotatably connected between the two support frames 1. One end of the bow 5 is provided with a rotation drive component 6. The bow 5 rotates around the spool support 2. After the wire core 4 is pulled out from the spool 3, it first enters from one end of the spool support 2, then exits from one end of the bow 5, and movably passes along the concave surface of the bow 5 to the other end of the bow 5, and finally exits from the bow 5.

[0035] The working principle of this utility model can be summarized as follows:

[0036] After the wire core 4 is pulled out from the wire reel 3, it first passes through one end of the wire reel support 2, then leads out from one end of the bow 5, and moves along the concave surface of the bow 5 to the other end of the bow 5, and finally passes out of the bow 5. During the wire release process, the rotation drive assembly 6 drives the bow 5 to rotate, and the bow 5 drives the wire core 4 to rotate around the wire reel support 2 and the wire reel 3, thereby completing the untwisting of the wire core 4.

[0037] Preferably, two bows 5 are provided and arranged symmetrically, forming an elliptical structure that rotates around the coil support 2. By providing two symmetrical bows 5, the rotational balance of the entire device is improved.

[0038] Preferably, the rotary drive assembly 6 includes a first motor 61, a drive pulley 62, a transmission belt 63, and a driven pulley 64. Hollow shafts 51 are fixedly connected to both ends of the drawbone 5. One end of each hollow shaft 51 is rotatably connected to the support frame 1. One hollow shaft 51 extends out of the support frame 1 and is fixedly connected to the driven pulley 64. The driven pulley 64 is connected to the drive pulley 62 via the transmission belt 63. The drive pulley 62 is connected to the output shaft of the first motor 61. Driven by the first motor 61, the pulley drive structure rotates the hollow shafts 51, thereby driving the drawbone 5 to rotate.

[0039] Preferably, the reel bracket 2 is rotatably connected to the end of the hollow shaft 51 away from the support frame 1. Because the winding surface of the wire core 4 is relatively wide, the reel bracket 2 has a certain swing capability, which can flexibly adjust the position of the wire core 4 during the unwinding process and avoid damage to the wire core 4.

[0040] Preferably, one end of the coil support 2 is provided with a first through hole 21 for the wire core 4 to pass through, and the first through hole 21 passes through the hollow rotating shaft 51. No matter how the bow 5 rotates, the wire core 4 can always pass through from the center of rotation, reducing the risk of damage to the wire core 4 caused by swinging friction.

[0041] Preferably, the hollow shaft 51 has a second through hole 52 at the end away from the support frame 1 for the wire core 4 to pass through. The wire core 4 is tangentially introduced into the hollow shaft 51 by the fixed pulley 53, or the wire core 4 is tangentially guided from the hollow shaft 51 to the fixed pulley 53, so that the moving path of the wire core 4 is constant and the oscillation wear is reduced.

[0042] Preferably, the outer edges of the first perforation 21 and the second perforation 52 are both rounded. The rounded corners can greatly prevent the wire core 4 from being worn or scratched.

[0043] Preferably, the bow 5 is rotatably connected to a plurality of fixed pulleys 53, and the wire core 4 is in rolling contact with the plurality of fixed pulleys 53.

[0044] A cabling machine includes multiple untwisting devices as described in the above embodiment. One untwisting device has a wire reel 3 connected to a second motor 7. This untwisting device is used as a cabling device; therefore, the orientation of the wire core 4 in the untwisting device is opposite to that in all other untwisting devices. The specific cabling principle is summarized as follows:

[0045] First, multiple sets of wire cores 4 are untwisted by different untwisting devices, and then they are inserted into the untwisting device, which is a cabling device. The insertion path is exactly the opposite of the other untwisting devices. Finally, they are fixed on the wire reel 3. The second motor 7 drives the wire reel 3 to rotate, winding multiple wire cores 4 onto the wire reel 3. As the untwisting device is running, the bow 5 will rotate around the wire reel support 2 continuously. Therefore, multiple wire cores 4 will be continuously twisted into a cable during the movement and finally wound onto the wire reel 3.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
