Description

Technical Field

[0001] This utility model relates to the technical field of wire and cable production equipment, and in particular to an auxiliary device for coiling and bundling wires and cables. Background Technology

[0002] In the wire and cable production process, coiling is a crucial step connecting cable extrusion molding with subsequent bundling and packaging. Its core requirements are ensuring accurate coil dimensions, uniform arrangement, and convenient unloading to adapt to the cable transportation and usage needs of different scenarios. Currently, coiling equipment for 10mm²-25mm² multi-core power cables generally suffers from technical defects, hindering production efficiency and product quality. Existing coiling equipment mostly adopts a fixed-diameter coiling disc or a mechanical linkage expansion and contraction structure design. The former requires disassembly and replacement of the entire coiling disc for different coiling outer diameters, and the changeover time for a single specification is ≥30 minutes. Moreover, the replacement process requires 2-3 people to work together, resulting in high labor costs. Although the latter can achieve expansion and contraction, it relies on the complex linkage of multiple sets of gears and connecting rods, which is prone to jamming due to component wear. In addition, manual prying of the coiled cable is required during unloading, which not only takes ≥30 seconds per coil, but also easily scratches the PVC insulation layer of the cable, resulting in an insulation layer thickness deviation exceeding the ≤0.2mm requirement specified in GB / T12706.1-2020, with a defect rate as high as 15%.

[0020] Please see Figure 1-4This utility model provides a technical solution: an auxiliary device for coiling and bundling wires and cables, including a machine frame 1, a rapid expansion and contraction coiling structure, and a cable laying assembly. The rapid expansion and contraction coiling structure is located in the middle of the machine frame 1, and the cable laying assembly is located on the left side of the machine frame 1, corresponding to the position of the rapid expansion and contraction coiling structure. An outer diameter detection sensor 16 is fixedly connected to the left side of the equipment frame 1. An expansion and contraction base 2 is fixedly connected to the center of the equipment frame 1. A motor base 11 is fixedly connected to the top of the expansion and contraction base 2. A servo motor 12 is installed on the top of the motor base 11. An encoder 15 is fixedly connected to the tail of the servo motor 12. A planetary reducer 13 is fixedly connected to the output end of the servo motor 12. A flange 14 is fixedly connected to the output end of the planetary reducer 13. The planetary reducer 13, through its multi-gear meshing transmission design, can reduce the high speed of the servo motor 12 to the low speed required for coiling, while amplifying the torque to ensure that the coiling disc skeleton 20 has sufficient power to overcome the resistance of cable winding, thus avoiding speed fluctuations due to insufficient torque. The high transmission accuracy of the planetary reducer 13 ensures that the speed signal of the servo motor 12 is accurately transmitted to the flange 14 and the coiling disc skeleton 20, avoiding eccentric rotation of the coiling disc due to transmission errors, thereby ensuring the inner diameter deviation of the coiling. A coiling disc frame 20 is fixedly connected to the flange 14. A cylinder seat 17 is fixedly connected inside the flange 14. The cylinder seat 17 is located inside the coiling disc frame 20.

The output end of the miniature cylinder 18 is fixedly connected to the expansion block 19. The expansion block 19 is directly connected to the miniature cylinder 18. With the help of the guide rod 21 and the sliding groove, it can achieve radial rapid expansion and contraction. It can adapt to the outer diameter of the coil without disassembly. The outer arc surface of the expansion block 19 has a pre-set anti-slip texture to effectively prevent the cable from slipping during the coiling rotation and ensure the coiling quality. The directional rod 21 is fixed at both ends of the forming disc frame 20 and cooperates with the sliding groove on the expansion and contraction block 19 to limit the movement direction of the expansion and contraction block 19 and ensure accurate forming size. The rapid expansion and contraction forming disc structure consists of an expansion and contraction base 2, a motor base 11, a servo motor 12, a planetary reducer 13, a flange 14, an encoder 15, a cylinder seat 17, a miniature cylinder 18, an expansion and contraction block 19, a forming disc skeleton 20, and a directional rod 21. A cable tray base plate 3 is fixedly connected to the left side of the equipment frame 1. A lead screw motor 9 is fixedly connected to the bottom of the cable tray base plate 3.

A lower bearing seat 7 is rotatably connected to the bottom of the ball screw 5. An upper bearing seat 4 is rotatably connected to the top of the ball screw 5. The upper bearing seat 4 and the lower bearing seat 7 are fixedly connected to the cable tray base plate 3. A lead screw nut 6 is rotatably connected to the ball screw 5. A guide rail 10 is provided on one side of the lead screw motor 9. A slider 22 is slidably connected on the guide rail 10. A nut fixing plate 23 is fixedly connected to the slider 22. The other side of the nut fixing plate 23 is fixedly connected to the lead screw nut 6. A cable tray 24 is fixedly connected to the nut fixing plate 23. The ball screw 5 is made of high-strength alloy steel, and with the rigid connection between the nut fixing plate 23 and the slider 22, it can maintain stable axial movement even when the cable tray 24 is carrying cables of different weights. The cable tray assembly consists of a base plate 3, an upper bearing seat 4, a ball screw 5, a screw nut 6, a lower bearing seat 7, a coupling 8, a screw motor 9, a guide rail 10, a slider 22, a nut fixing plate 23, and a cable tray frame 24.

[0021] Working principle: After the equipment is powered on, the servo motor 12 and the lead screw motor 9 enter the standby state, the encoder 15 starts, calibrates the initial speed and position of the servo motor 12 to ensure the accuracy of subsequent circular rotation, and the outer diameter detection sensor 16 starts to collect the outer diameter data of the cable entering the equipment in real time and transmit the data to the control system to provide a basis for the adjustment of the cable pitch of the cable assembly. The control system sends a command to the micro cylinder 18, the piston rod of the micro cylinder 18 extends, and pushes the expansion block 19 to move outward along the slide groove of the directional rod 21 until the expansion block 19 forms an annular reference surface. The directional rod 21 ensures that there is no radial offset during the movement of the expansion block 19, thus ensuring the accuracy of the ring size. The operator passes one end of the cable through the detection area of ​​the outer diameter detection sensor 16 and the guide groove of the cable tray 24 in sequence, and finally fixes it on the outer arc surface of the expansion block 19. At this time, the outer diameter detection sensor 16 continuously feeds back the cable outer diameter data, and the control system sets the cable pitch of the cable tray assembly according to the data. The control system sends a start command to the servo motor 12, and the servo motor 12 outputs power. After being reduced in speed and increased in torque by the planetary reducer 13, it drives the coiling disc skeleton 20 to rotate through the flange 14. The coiling disc skeleton 20 synchronously drives the expansion block 19 to rotate. The cable begins to wind into a coil as the expansion block 19 rotates. The encoder 15 collects the speed signal of the servo motor 12 in real time and feeds it back to the control system to dynamically adjust the output torque of the servo motor 12 to ensure stable coiling rotation speed and avoid speed fluctuations due to load changes. At the same time as the starting process begins, the control system sends a start command to the lead screw motor 9. The lead screw motor 9 outputs power, which is transmitted to the ball screw 5 through the coupling 8, causing the ball screw 5 to rotate. The lead screw nut 6 slides up and down along the axis of the ball screw 5 as the ball screw 5 rotates. Since the lead screw nut 6 is connected to the nut fixing plate 23, and one side of the nut fixing plate 23 is connected to the slider 22, the cooperation between the slider 22 and the guide rail 10 restricts the rotation of the nut fixing plate 23, allowing it to slide stably along the direction of the guide rail 10, thereby driving the cable tray 24 to slide up and down synchronously. The sliding speed of the cable tray 24 is precisely matched with the rotation speed of the servo motor 12, so as to achieve the axial uniform arrangement of the cable on the expansion block 19. Under the continuous thrust of the micro cylinder 18, the expansion block 19 remains in an outward expansion state to ensure the stability of the outer diameter of the coil. The guide rod 21 cooperates with the sliding groove of the expansion block 19 to prevent radial displacement during the rotation of the expansion block 19 and avoid elliptical or eccentric coiling. The outer diameter detection sensor 16 continuously monitors the outer diameter of the cable. If the outer diameter of the cable deviates, the control system immediately adjusts the speed of the lead screw motor 9 and synchronously changes the sliding speed of the cable tray 24 to ensure that the cable pitch always matches the outer diameter of the cable and the arrangement gap is stable. The control system accumulates the coil length in real time based on the number of rotations of the servo motor 12 collected by the encoder 15 according to the preset coil length. When the accumulated length reaches the set value, the control system sends a stop command, and the servo motor 12 and the lead screw motor 9 decelerate synchronously to stop, so as to prevent the cable from becoming loose due to inertia. After shutdown, the control system sends a retraction command to the micro cylinder 18. The piston rod of the micro cylinder 18 retracts, pulling the expansion block 19 inward along the slide groove of the directional rod 21. The outer arc surface of the expansion block 19 disengages from the coiled cable. The operator or subsequent binding mechanism can directly remove the coiled cable from the outside of the coiling disc frame 20, completing a single coiling operation. Subsequently, the micro cylinder 18 extends again, the expansion block 19 returns to its initial outward expansion state, and the equipment enters the next round of coiling standby.
