DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments. Example 1

[0022] like Figure 1-Figure 2 As shown, a device for cabling machine without reeling and rotating specifications includes a wire-paying device and a cabling device. The wire-paying device can provide wire cores for the cabling device, and the cabling device can twist the wire cores.

[0023] The pay-off device includes at least three pay-off machines and crimping machines. The pay-off machines are divided into two groups and are staggered at a certain distance. The wire cores that need to be twisted are provided on the pay-off machines. The wire cores on the pay-off machines are connected to the cabling device or to one end of the crimping machine. The pay-off machines can provide, that is, the wire core specifications set on the pay-off machines include main line and water line.

[0024] In this embodiment, there are 6 pay-off machines, namely pay-off machine 1, pay-off machine 2, pay-off machine 3, pay-off machine 4, pay-off machine 5, and pay-off machine 6. They are placed side by side in two rows and spaced a certain distance apart to facilitate the wire core to achieve a better twisting direction.

[0025] In this embodiment, the pay-off machine uses a fork-type bracket with telescopic top shafts at both ends of the fork. The wire drum is closed and clamped on the pay-off machine by the telescopic top shaft. The wire drum can rotate axially around the telescopic top shaft to provide the wire core for the cabling device.

[0026] In this embodiment, a guide wheel is installed in front of the pay-off machine to guide the wire cores to the cabling device for stranding. The wire cores at the output of pay-off machines 1-5 are connected to the cabling device via the guide wheel. The wire cores at the output of pay-off machine 6 are connected to crimping machine 7, serving as a standby pay-off machine. The wire cores installed on pay-off machines 1-5 are produced in a specification of 3 main wires + 2 water wires or 4 main wires + 1 water wire.

[0027] When it is necessary to convert between different specifications, when the core of the pay-off machine that needs to replace the core is about to run out, the end of the core can be set at one end of the crimping machine 7. In this embodiment, the core of the pay-off machine 5 needs to be replaced with the core of the pay-off machine 6.

[0028] When the wire core on the pay-off machine 5 is about to run out, the end of the wire core on the pay-off machine 5 is placed on one end of the crimping machine 7, and the top of the wire core on the pay-off machine 6 is placed on one end of the crimping machine 7. The two wire cores are connected by the crimping machine 7, so that the wire core on the pay-off machine 6 can follow the end of the wire core of the pay-off machine 5 into the cabling device for twisting. This ensures that the conversion between different specifications is more convenient and reduces the trouble of manual stripping, loose branches and re-threading.

[0029] Reference Figure 2 The crimping machine 7 is a vertical box-shaped structure consisting of a crimping die 71 and a support device 72. The crimping die 71 is mounted on top of the support device 72. The crimping machine 7 is positioned at the same height as the pay-off machine, ensuring that the wire cores are docked and crimped at the optimal height. The crimping machine 7 uses the crimping device 71 to crimp and fine-tune the outer diameter of the wire cores, achieving coaxial docking. This ensures that the wire cores are smoothly aligned and free of misalignment during the switching process, and that the wire cores maintain consistent dimensions and continuous tension upon entering the cabling device.

[0030] A support device 72 is provided at the bottom of the crimping machine 7. The support device 72 is a square base. A hydraulic system is provided inside the support device 72, and a crimping die 71 is provided on the top. A universal wheel 721 is also provided at the bottom of the support device 72. The universal wheel 721 can drive the crimping machine 7 to move and change positions within the working space, which can facilitate the docking of the pay-off machine or the adjustment of the position according to the production layout.

[0031] The crimping machine 7 crimps the wire cores using a hydraulic system housed within a support device 72. A crimping tube is located at the center of the crimping die 71, where the two wire cores are crimped. The tube adjusts the outer diameter of the wire cores, ensuring they remain consistent. After crimping, the tube remains in place at the junction of the two wire cores, allowing them to be twisted together.

[0032] The crimping machine 7 uses the crimping die 71 to complete the precise crimping and docking of the two wire cores at the end, ensuring that when the wire core on one pay-off machine is exhausted, it can be connected to the wire core on another pay-off machine, reducing wire defects caused by loose joints or inconsistent outer diameters. The hydraulic system can crimp the wire cores, and a crimping tube is also provided at the crimping point to avoid problems such as wire breakage, loose wires, or uneven compression at the joints. After the crimping machine 7 completes the crimping, the new wire core can continue to enter the cabling process, realizing the replacement of the wire core without stopping the machine. The specifications of the wire core can be changed when the wire core is replaced, realizing the specification change without taking the reel off.

[0033] Reference Figure 1 The cabling device includes a doubling die 8, a wrapping head 9, a crawler 10, and a take-up machine 11. A splitter plate is located in front of the doubling die 8. This plate allows for preliminary assembly of the wire cores from the various pay-off machines, ensuring that the stranded wires maintain the correct arrangement order. In this embodiment, the splitter plate is a disc-shaped structure with holes for securing the wire cores. The wire cores pass through the corresponding holes on the splitter plate and are combined in the order required by the process.

[0034] A taping head 9 is located behind the stranding die 8. After the strands are twisted, the outer layer of the wires is wrapped with tape. This ensures a tight core structure and even distribution of the wires. The taping head typically takes the form of a rotating wheel or rotary head, capable of winding mica tape, paper tape, or other auxiliary materials.

[0035] The crawler 10 is located behind the wrapping head 9. It pulls and guides the wire cores forward, allowing the stranded wire cores to be delivered to the take-up frame 11 at a stable speed and tension. The crawler 10 is a belt-like transmission mechanism that adjusts the clamping force according to the wire core size, ensuring that the entire cable core is not flattened during the stranding process on the cabling machine.

[0036] After being pulled by the crawler 10, the wire core is connected to the wire take-up machine 11, which can reel the processed wire core onto the wire reel for subsequent unloading or packaging. In this embodiment, the wire take-up machine 11 is equipped with an adjustable wire arrangement device to ensure that the finished wire cores are neatly arranged on the reel for easy transportation and storage.

[0037] In this embodiment, each pay-off machine 1-5 can provide the main line or water line for the paralleling die 8; by docking the wire core on the pay-off machine 6 with the crimping machine 7, before the wire core that needs to be replaced in the pay-off machine 1-5 is about to be used up, the wire core is set at the other end of the crimping machine 7, and the two wire cores are connected through the crimping machine 7, which can ensure that the wire core specification is converted without interruption and can ensure that the production line can maintain high efficiency and continuous operation.

[0038] The method of using this device is: Step 1: Set up multiple pay-off machines: Pay-off 1, Pay-off 2, Pay-off 3, Pay-off 4, and Pay-off 5. Pay-off machines 1-5 directly supply cores to the cabling device, with an additional pay-off machine 6 in standby mode. The cores output by pay-off machines 1-5 are arranged and specified according to production requirements.

[0039] Step 2: When the wire core on one of the pay-off machines is nearly used up and needs to be converted to a wire core of a different specification or another winding core, the end of the wire core is introduced into one end of the crimping machine 7. In this embodiment, the wire core on the pay-off machine 5 is used up and needs to be replaced.

[0040] Step 3: The unwinding machine 6 is provided with a new wire core or a wire core of different specifications, and the end of the wire core is introduced into the other end of the crimping machine 7.

[0041] Step 4: The two wire cores are crimped together within the crimping tube of the crimping die 71. This crimping is driven by a hydraulic system, connecting the two wire cores and adjusting the outer diameter of the wire core at the connection. In this embodiment, the wire cores at the crimping connection are the end of the pay-off machine 5 and the head of the pay-off machine 6.

[0042] Step 5: After the core crimping is completed and the tension of the pay-off machine 6 is adjusted to meet the requirements, the core of the standby pay-off machine 6 is connected to the cabling device to replace the exhausted core, ensuring that the cabling device does not need to be shut down to achieve specification conversion.

[0043] In this embodiment, the diameter of the crimping tube is adjusted according to the diameter of the wire core to ensure that the crimping tube can tightly connect the two wire cores. After the wire core provided by the pay-off machine 6 enters the cabling device, the tension of the pay-off machine is adjusted to meet the twisting requirements of the cabling device.

[0044] In this embodiment, a crimping machine 7 rapidly connects two cable cores, eliminating the traditional process of stopping the machine, stripping, unbundling, and splicing. Multiple pay-off machines, in conjunction with the crimping machine 7, enable rapid switching of cable cores, reducing downtime and increasing production capacity. This significantly reduces operator workload and the risk of human error, while also ensuring consistent cable quality.

[0045] The crimping die 71 adjusts the diameter of the wire cores to ensure a smooth transition between the outer diameters of the two cores at the connection point. Before the connected cores enter the cabling device, the pay-off machine adjusts the tension of the cores to ensure the stability of the combined cores during the doubling, wrapping, traction, and take-up processes.

[0046] A supporting device 72 is provided at the bottom of the crimping mold 71, and a universal wheel 721 is provided at the bottom of the supporting device 72. The crimping machine 7 can move the position of the crimping machine 7 through the universal wheel 721, and can adjust the wire core position provided by the wire pay-off machine.
