Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cable processing, and more specifically, to a cable cabling machine with stable cable laying. Background Technology

[0002] In the cable manufacturing process, the cabling machine is the core equipment for stranding multiple insulated cores into a cable. It needs to release multiple sets of cables simultaneously from the pay-off reel and wind them into a whole according to a preset stranding angle and pitch, laying the foundation for subsequent sheath processing. The stability of the pay-off during the cabling process directly determines the structural regularity and electrical performance of the cable after cabling. However, as cables develop towards multi-core and smaller diameters, the pay-off defects of traditional cable cabling machines are becoming increasingly obvious: existing cabling machines generally have poor pay-off stability, and problems such as cable tension fluctuations, wire skipping, or uneven pay-off speeds are prone to occur during the pay-off process, seriously affecting the quality of cabling and production continuity.

[0003] Traditional cable forming machines typically employ a simple passive feeding mechanism, relying solely on the machine's traction to rotate the feeding reel and feed the cable. This lacks active speed control and tension adjustment. When there are slight differences in cable diameter across multiple feeding reels, or when wear on the reel bearings causes uneven resistance, some cables may be fed too quickly or too slowly. Feeding too quickly can cause the cable to loosen and accumulate, forming bulges during stranding. Feeding too slowly can lead to excessive cable tension, resulting in stretching deformation or even breakage, forcing production to stop.

[0004] Therefore, developing a cable forming machine with stable cable laying function has become an urgent need to improve cable forming quality and ensure continuous production. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a cable forming machine with stable cable laying, which solves the technical problems of poor cable laying stability in existing cable forming machines, and the easy occurrence of cable tension fluctuations, wire skipping, or uneven laying speed during the cable laying process.

[0006] According to one aspect, at least one embodiment of this disclosure provides a cable bundling machine with stable cable laying, comprising: A base plate and a rotating disk, wherein the rotating disk is disposed on the base plate; Side plate and drive rotation assembly, the side plate is fixed to the surface of the base plate, and the drive rotation assembly is disposed on the base plate and the side plate; A wire feeding assembly, which is disposed on the rotary table; The wire feeding assembly includes several drive shafts, all of which are horizontally rotatably connected to the side surface of the rotating disk. Each drive shaft has a drive gear at one end. The side surface of the rotating disk has several pairs of support rods, each of which has a docking groove at its front end. A wire feeding reel is inserted into a pair of docking grooves.

[0007] As a further technical solution, the outer ends of the support rods are all fixedly connected to a clamping sleeve by bolts. The clamping sleeve is attached to the transmission connection of the pay-off reel, and a driven gear is provided at the lower end of the pay-off reel.

[0008] As a further technical solution, a drive motor is provided on the side surface of the side plate, a main gear is provided at the output end of the drive motor, and a secondary gear is provided at one end of the transmission shaft. The main gear meshes with several of the secondary gears.

[0009] According to another aspect, in at least one embodiment of the present invention, the drive rotation assembly includes an outer frame, the outer frame is fixed to the surface of the base plate, a transmission groove is provided in the outer frame, and the rotating disk is rotatably connected in the transmission groove.

[0010] As a further technical solution, an outer ring gear is provided around the side surface of the rotating disk, a second motor is provided at the lower end of the side surface of the side plate, and a second gear is provided at the output end of the second motor, the second gear meshing with the outer ring gear.

[0011] As a further technical solution, both the driving gear and the driven gear are bevel gears.

[0012] As a further technical solution, the inner surface of the docking groove has a U-shaped opening structure.

[0013] As a further technical solution, anti-detachment bushings are fitted at both the upper and lower ends of the wire feeding reel, and the anti-detachment bushings are fixedly fitted to the docking groove.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the wire feeding assembly solves the problems of uneven wire feeding speed and tension fluctuations in traditional cable forming machines through synchronous drive and multi-directional fixing design. The drive motor drives all transmission shafts to rotate synchronously via the main gear and auxiliary gear, and then drives the wire feeding reels through the drive gear and driven gear, ensuring that the speed of multiple wire feeding reels is consistent and preventing cable slack or stretching. The mating groove of the support rod cooperates with the clamping sleeve to fix the wire feeding reels axially and radially, preventing deviation or movement during wire feeding. The anti-detachment bushing further enhances stability and reduces the impact of vibration. This structure eliminates the need for manual adjustment of the wire feeding speed, significantly reduces the risk of wire skipping and breakage, ensures stable cable tension, provides a uniform wire feeding foundation for subsequent cable forming, and improves cable forming quality and production continuity.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-4 As shown, it illustrates a cable-laying machine with stable cable laying according to an embodiment of the present disclosure, comprising: A base plate 1 and a rotating disk 2, wherein the rotating disk 2 is disposed on the base plate 1; Side plate 3 and drive rotation assembly 5, the side plate 3 is fixed on the surface of the base plate 1, and the drive rotation assembly 5 is disposed on the base plate 1 and the side plate 3; The wire feeding assembly 4 is disposed on the rotary disk 2; The wire feeding assembly 4 includes several drive shafts 4-1, each of which is horizontally rotatably connected to the side surface of the rotating disk 2. Each drive shaft 4-1 has a drive gear 4-2 at one end. The side surface of the rotating disk 2 has several support rods 4-3, each with a docking groove 4-4 at its front end. A wire feeding reel 4-5 is inserted into a pair of docking grooves 4-4. Each support rod 4-3 has a clamping sleeve 4-6 fixedly connected to its outer end by bolts. The clamping sleeve 4-6 fits against the transmission connection of the wire feeding reel 4-5. A driven gear 4-7 is located at the lower end of the wire feeding reel 4-5. A drive motor 4-8 is located on the side surface of the side plate 3. A main gear 4-9 is located at the output end of the drive motor 4-8. Each drive shaft 4-1 has a secondary gear 4-10 at one end, and the main gear 4-9 meshes with several secondary gears 4-10.

[0024] In some examples, in order to achieve stable and synchronous cable feeding of multiple feed reels 4-5 and avoid uneven cable tension, tangling, or displacement due to inconsistent rotation speeds of the feed reels 4-5 during traditional cable feeding processes, a cable feeding assembly 4 is designed. This assembly includes several drive shafts 4-1 that rotate horizontally within the side surface of the rotating disk 2, providing rotational support for the drive gear 4-2 and the auxiliary gear 4-10. The auxiliary gear 4-10 at one end of the drive shaft 4-1 meshes with the main gear 4-9 at the output end of the drive motor 4-8 on the side surface of the side plate 3, forming a main-multiple-auxiliary gear transmission mechanism. When the drive motor 4-8 is running, the main gear 4-9 synchronously drives all the auxiliary gears 4-10 to rotate, thereby driving the drive shaft 4-1 and the drive gear 4-2 to rotate synchronously, ensuring that the rotation speeds of each drive shaft 4-1 are completely consistent.

[0025] Several pairs of support rods 4-3 on the side surface of the rotating disk 2 provide installation support for the pay-off reel 4-5. The mating groove 4-4 at the front end of the support rod 4-3 can accurately position the two ends of the pay-off reel 4-5, preventing lateral displacement of the pay-off reel 4-5 during installation. The clamping sleeve 4-6, which is fixed to the outer end of the support rod 4-3 by bolts, fits against the outer surface of the anti-detachment bushing 6 of the pay-off reel 4-5, which can firmly fix the pay-off reel 4-5 to the support rod 4-3 from the axial direction, preventing the pay-off reel 4-5 from axially moving due to vibration or tension during the pay-off process, and ensuring stable rotation of the pay-off reel 4-5.

[0026] The driven gear 4-7 at the lower end of the pay-off reel 4-5 meshes with the drive gear 4-2 at one end of the transmission shaft 4-1. When the transmission shaft 4-1 drives the drive gear 4-2 to rotate, the drive gear 4-2 can drive the driven gear 4-7 to rotate synchronously with the pay-off reel 4-5, realizing active pay-off and avoiding the cable from losing control of the pay-off speed due to its own weight. At the same time, all pay-off reels 4-5 are controlled by the same drive motor 4-8 through gear linkage, ensuring that the pay-off speed of each pay-off reel 4-5 is completely synchronized, effectively controlling the cable tension and preventing the cable from being stretched, deformed or broken due to tension differences.

[0027] During operation, the drive motor 4-8 drives the transmission shaft 4-1 to rotate via the main gear 4-9 and the auxiliary gear 4-10; the transmission shaft 4-1 drives the pay-off reel 4-5 to rotate and pay off the cable via the drive gear 4-2 and the driven gear 4-7; the clamping sleeve 4-6 and the docking groove 4-4 fix the position of the pay-off reel 4-5. The gear linkage ensures synchronous cable pay-off, the multi-directional fixing ensures stable cable pay-off, and the cooperation of all components achieves stable and synchronous cable pay-off, meeting the requirements of cable cabling processing.

[0028] like Figures 1-4As shown in the figure, the driving rotation assembly 5 in this embodiment includes an outer frame 5-1, which is fixed to the surface of the base plate 1. A transmission groove 5-2 is provided inside the outer frame 5-1. The rotating disk 2 is rotatably connected to the transmission groove 5-2. An outer ring gear 5-3 is provided around the side surface of the rotating disk 2. A second motor 5-4 is provided at the lower end of the side surface of the side plate 3. A second gear 5-5 is provided at the output end of the second motor 5-4. The second gear 5-5 meshes with the outer ring gear 5-3.

[0029] In some examples, to achieve uniform rotation control of the rotating disk 2 and precisely match the feeding rhythm of the feeding assembly 4, and to avoid uneven cable arrangement or unstable rotation affecting the feeding stability due to fluctuations in the rotation speed of the rotating disk 2, a drive rotation assembly 5 is designed. This assembly includes an outer frame 5-1 fixed to the surface of the base plate 1. The transmission groove 5-2 inside the frame provides an annular rotation space for the rotating disk 2. The rotating disk 2 is rotatably connected in the transmission groove 5-2. The inner wall of the transmission groove 5-2 can form a radial limit on the rotating disk 2, preventing lateral deviation or shaking during rotation, and ensuring that the rotating disk 2 always rotates stably around a fixed axis. The support structure of the outer frame 5-1 can also distribute the weight of the rotating disk 2, preventing the bottom of the rotating disk 2 from being deformed due to long-term stress, and extending the service life of the components. The outer ring gear 5-3 around the side surface of the rotating disk 2 meshes with the second gear 5-5 at the output end of the second motor 5-4 at the lower end of the side surface of the side plate 3, forming a stable gear transmission mechanism. When the second motor 5-4 is running, the second gear 5-5 drives the outer ring gear 5-3 to rotate synchronously with the rotating disk 2. By controlling the speed of the second motor 5-4, the rotation speed of the rotating disk 2 can be precisely adjusted to perfectly match the wire feeding speed of the wire feeding assembly 4, ensuring that the cable can be wound evenly into a cable and avoiding cable accumulation due to excessive speed or excessive cable tension due to excessive speed.

[0030] Compared with other transmission methods, gear transmission has the advantages of precise transmission ratio and stable power transmission. It can effectively control the speed fluctuation of the rotating disk 2, ensure that the rotating disk 2 rotates at a uniform speed, and thus ensure that the pitch is uniform when the cable is bundled, thereby improving the quality of the bundled cable.

[0031] In addition, the symmetrical support structure of the outer frame 5-1 and the side plate 3 can provide stable support for the rotating disk 2 from both sides, further enhancing the stability of the rotating disk 2 during rotation; the second motor 5-4 is installed at the lower end of the side surface of the side plate 3, with a reasonable layout that facilitates maintenance and repair, while avoiding the impact of vibration generated during motor operation on other components.

[0032] During operation, the second motor 5-4 drives the rotating disk 2 to rotate at a constant speed through the second gear 5-5 and the outer ring gear 5-3; the transmission groove 5-2 provides support and limit for the rotating disk 2. The gear transmission ensures uniform rotation, the ring support ensures rotational stability, and the coordinated control of all components controls the uniform rotation of the rotating disk 2, precisely cooperating with the wire feeding assembly 4 to feed the wire, thereby improving the quality and efficiency of cable production.

[0033] For example, such as Figure 1 As shown, both the driving gear 4-2 and the driven gear 4-7 are bevel gears.

[0034] In some examples, both the drive gear 4-2 and the driven gear 4-7 are bevel gears. The meshing of bevel gears enables power transmission between spatially intersecting shafts, adapting to the vertical layout of the drive gear 4-2 and the driven gear 4-7. Power transmission can be completed without additional adjustment of the shaft installation direction, simplifying the component structure design. The bevel gears have a large tooth surface contact area, which can evenly distribute the force during the transmission process, reduce the load on a single tooth, reduce the gear wear rate, and extend the service life.

[0035] For example, such as Figure 1 As shown, the inner surface of the docking groove 4-4 has a U-shaped opening structure.

[0036] In some examples, the inner surface of the docking groove 4-4 has a U-shaped opening structure. The open design of the U-shaped opening facilitates the quick insertion of the pay-off reel 4-5 into the docking groove 4-4, completing the initial positioning without the need for precise alignment. This greatly simplifies the installation process of the pay-off reel 4-5, reduces installation time, and improves the ease of operation of the equipment. The arc-shaped inner wall of the U-shaped structure can form a close fit and support with the bushings at both ends of the pay-off reel 4-5, increasing the contact area and preventing the bushings from deforming due to excessive local stress when the pay-off reel 4-5 rotates to pay off the wire.

[0037] For example, such as Figure 4 As shown, anti-detachment bushings 6 are fitted on both the upper and lower ends of the wire feeding reel 4-5, and the anti-detachment bushings 6 are fixedly fitted to the docking groove 4-4.

[0038] In some examples, the anti-detachment bushings 6 fitted at both ends of the pay-off reel 4-5 are fixedly fitted to the mating groove 4-4. The anti-detachment bushings 6 fill the gap between the bushings of the pay-off reel 4-5 and the mating groove 4-4, preventing radial wobble of the pay-off reel 4-5 during rotation and ensuring that the pay-off reel 4-5 always rotates stably around a fixed axis, preventing cable deflection due to wobble. The anti-detachment bushings 6 are made of elastic material, which can generate a certain pre-tightening force when fitted, enhancing the tightness of the connection between the pay-off reel 4-5 and the mating groove 4-4, while buffering vibrations during the pay-off process and reducing impact damage to the pay-off reel 4-5 and the mating groove 4-4.

[0039] In practical use: Insert both ends of the wire feeding reel 4-5, with the cable wound around it, into the mating grooves 4-4 of the support rod 4-3 on the side surface of the rotating disk 2. Secure the clamping sleeve 4-6 at the outer end of the support rod 4-3 with bolts, so that the clamping sleeve 4-6 fits against the anti-detachment bushing 6 of the wire feeding reel 4-5, thus fixing the wire feeding reel 4-5. Start the drive motor 4-8 of the wire feeding assembly 4. The main gear 4-9 drives all the auxiliary gears 4-10 to rotate synchronously, thereby driving the transmission shaft 4-1 and the drive gear 4-2 to rotate. The drive gear 4-2 meshes with the driven gear 4-7 at the lower end of the wire feeding reel 4-5, driving the wire feeding reel 4-5 to feed the cable at a uniform speed. At the same time, start the second motor 5-4 of the drive rotating assembly 5. The second gear 5-5 meshes with the outer ring gear 5-3 of the rotating disk 2, driving the rotating disk 2 to rotate smoothly along the transmission groove 5-2 of the outer frame 5-1. The rotation direction of the rotating disk 2 is adapted to the wire feeding direction, ensuring that multiple sets of cables are twisted into a cable at a preset angle. During the wire feeding process, the docking groove 4-4 and the anti-detachment bushing 6 restrict the offset of the wire feeding reel 4-5. All wire feeding reels 4-5 operate synchronously to avoid tension fluctuations, achieving stable wire feeding and precise cabling throughout the process. After cabling is completed, the motor is turned off, and the wire feeding reel 4-5 can be replaced by loosening the clamping sleeve 4-6.
