Description

Technical Field

[0001] This utility model relates to a cable winding and unwinding device, specifically an anti-tangling cable winding and unwinding device for electromechanical equipment, belonging to the technical field of cable winding and unwinding equipment. Background Technology

[0002] Electromechanical equipment often requires frequent take-up and unwinding of large quantities of cables during operation. Cable take-up and unwinding devices, as key tools for cable management, use a reel structure to orderly wind and store loose cables, avoiding problems such as tangling, knotting, abrasion, and scratches caused by haphazard stacking. This not only keeps the space tidy but also effectively protects the cable insulation and internal conductors. However, traditional cable take-up and unwinding devices commonly suffer from the technical challenge of cable tangling during long-term, high-frequency use, which has become a major bottleneck restricting the improvement of the automation level of related equipment.

[0003] To address this issue, existing technologies, such as CN222647311U, disclose a cable winding device for electrical engineering construction. This device includes a mounting plate and a reciprocating groove rod rotatably mounted on the front of the cable assembly. A motor drives the reciprocating groove rod to rotate, causing a slider to reciprocate left and right. The slider has a sliding guide plate that adaptively adjusts according to changes in the cable roll diameter, resulting in neater cable winding and preventing tangling and knotting. Another example is CN221479104U, which discloses a limiting mechanism for a cable winding and unwinding device. This mechanism uses a reciprocating screw to drive a moving block in a uniform reciprocating motion, causing the winding and unwinding limiting hole to move synchronously and uniformly with the cable. This ensures the cable is neatly and regularly wound on the winding and unwinding rollers, preventing tangling and the accumulation of multiple turns of cable in the same spot, resulting in a more even and neat distribution of the wound cable. While the aforementioned existing technologies have improved the cable winding and unwinding effect to some extent, the reciprocating speed of the winding mechanism in these existing devices is usually set to a fixed value by a single drive source. As the number of winding turns increases during the cable winding process, the radius of the cable loop on the winding rod gradually increases, and the circumference of the cable wound per rotation also increases. If the lateral movement speed of the winding mechanism remains unchanged, the pitch between each layer of cable will continuously decrease, causing the subsequently wound cables to be unable to be neatly arranged in the gaps of the previous layer of cable. This easily leads to overlapping, misalignment, or even local accumulation, ultimately causing serious tangling and knotting problems. Secondly, the clamping or pressing mechanisms in existing devices are mostly fixed elastic pressing structures. Although they can passively move outward as the coil diameter increases, they cannot feed back the displacement of the coil diameter change to the cable laying drive system. The cable laying speed cannot be dynamically matched and adjusted with the coil diameter change, resulting in the device only being able to maintain a good cable laying effect within a specific coil diameter range. Under working conditions with large coil diameter changes, the cable laying quality drops significantly. Therefore, how to enable the cable laying speed to automatically adjust in real time, continuously and accurately with the change of cable coil diameter during the winding process, so as to maintain neat arrangement and avoid tangling throughout the entire cable winding process, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] This invention provides an anti-tangling cable winding device for electromechanical equipment to solve the problem that existing cable winding devices cannot adjust the cable laying speed in real time according to the continuous change of the cable roll diameter during the winding process, resulting in a mismatch between the cable laying speed and the winding speed.

[0005] The present invention achieves the above objectives through the following technical solution: a cable winding and unwinding device for anti-tangling electromechanical equipment, including a winding rod, a clamping rod, a cable management plate and an adjustment drive box, wherein the cable passing through the cable management plate is wound and wrapped around the body of the winding rod at a constant speed and tension, and the body of the clamping rod is in close contact with the outside of the cable wound by the winding rod.

[0012] As a further improvement of this utility model: the outer rail of the annular C-shaped guide rail is provided with a notch groove, and the inner rail of the annular C-shaped guide rail is embedded with several rolling shafts, and the belt of the annular drive belt rolls and fits in close contact with the rolling shafts.

[0013] As a further embodiment of this utility model: the continuously variable speed control assembly also includes a hydraulic drive outer tube, a friction transmission wheel, and a hydraulic telescopic tube. The hydraulic drive outer tube is fixedly connected to the body of the adjustment drive box. The hydraulic telescopic tube is movably sleeved inside the hydraulic drive outer tube. The friction transmission wheel is coaxially fixedly sleeved on the end of the hydraulic telescopic tube located outside the hydraulic drive outer tube, and the friction transmission wheel is tightly attached between the cone surfaces of the driving conical rotor and the driven conical rotor. A piston is coaxially fixedly connected to the end of the hydraulic telescopic tube located inside the hydraulic drive outer tube. A hydraulic delivery pipe is connected between the hydraulic drive outer tube and the movable cavity. The hydraulic drive outer tube, the movable cavity, and the hydraulic delivery pipe are all filled with hydraulic oil. A limit rod is movably inserted inside the hydraulic telescopic tube, and the outer end of the limit rod is fixedly connected to the adjustment drive box.

[0014] As a further embodiment of this utility model: the driven conical rotor is coaxially fixedly connected to the driving conical gear located outside the adjustment drive box, and the lower plate of the cable management plate is rotatably connected to the driven conical gear and the friction drive disk. The driven conical gear and the friction drive disk are coaxially fixedly connected, and the driven conical gear and the driving conical gear are meshed. Part of the wheel body of the friction drive disk passes through the notch and is tightly fitted to the belt body of the annular drive belt.

[0015] As a further embodiment of this utility model: the base plate can also be detachably connected with a cable shell and a motor shell. The cable shell is covered on the outside of the cable winding area, and the motor shell is covered on the outside of the constant tension winding motor installation area. The cable shell has a cable through groove, and the position of the cable through groove corresponds to the position of the movable groove on the cable management plate.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model is equipped with a winding rod, a clamping rod, a cable management plate, and an adjustment drive box. The cable passing through the cable management plate is wound around the body of the winding rod at a constant speed and tension. The body of the clamping rod is close to the outside of the cable wound by the winding rod. The cable management plate ensures that the cable can be guided by the cable arrangement before entering the winding stage, while the body of the clamping rod is always close to the outermost layer of the cable wound on the winding rod. It can apply radial pressure to the wound cable, which not only effectively compacts the wound cable coils and prevents the disorder and crossing caused by loosening, but also adaptively moves outward as the radius of the cable coil increases, always maintaining the contact pressure. This ensures that the cable is neatly and tightly arranged on the winding rod with constant tension, eliminates the risk of entanglement caused by tension fluctuations or disordered arrangement, and improves the stability of cable winding and unwinding operations.

[0018] 2. The cable management plate of this utility model is connected to a ring-shaped C-shaped guide rail at its lower part. A ring-shaped drive belt is movably installed inside the ring-shaped C-shaped guide rail. A continuously variable speed control component is installed in the adjustment drive box. The power input end of the continuously variable speed control component is synchronously connected to the winding rod, and the power output end of the continuously variable speed control component is connected to the ring-shaped drive belt. The clamping rod gradually moves as the radius of the cable coil wound by the winding rod increases. A hydraulic synchronous adjustment mechanism is provided between the continuously variable speed control component and the winding rod. The continuously variable speed control component enables the speed of the cable arrangement to be synchronized with the rotation speed of the cable winding. The hydraulic synchronous adjustment mechanism between the continuously variable speed control component and the winding rod... The structure can sense the displacement change of the clamping rod as the cable winding radius increases in real time, and convert this mechanical displacement into a hydraulic signal. Then, it can steplessly adjust the transmission ratio of the stepless speed regulating component, thereby dynamically changing the speed of the ring drive belt. As the cable is wound thicker and thicker on the winding rod, the lateral movement speed of the conductor ring will slow down accordingly to match the required wire laying stroke for each turn of cable. This ensures that the cable is always tightly arranged with the best cutting angle. Whether at the beginning or end of winding, the pitch of the wire laying can match the winding speed, eliminating the problem of overlapping or excessive gap caused by the mismatch between the wire laying speed and the winding speed, and further improving the anti-winding effect.

[0019] 3. The cable management plate of this utility model has movable slots on its body. A wire ring is connected to the body of the annular drive belt. The wire ring is sleeved on the cable body and moves synchronously within the movable slot area along the winding path of the cable. The movable slots provide a straight path constraint for the reciprocating movement of the wire ring, preventing it from swaying during movement. The wire ring is fixedly connected to the body of the annular drive belt, so that the lateral movement power of the wire ring comes directly from the stepless speed regulation component, realizing the linkage between the cable laying action and the winding action. During the winding process, the wire ring will reciprocate linearly within the limited range of the movable slot at a speed that matches the rotation speed of the winding rod and the current cable diameter, thereby guiding the cable to be arranged tightly and neatly layer by layer on the winding rod. This ensures that the cable is accurately positioned and orderly arranged in each turn on the winding rod. During the cable release process, the cable can also be guided to be released from the winding rod in a neat layer by layer. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] Example 1

[0032] like Figures 1 to 9As shown, an anti-tangling cable winding and unwinding device for electromechanical equipment includes a winding rod 4, a clamping rod 5, a cable management plate 6, and an adjusting drive box 7. The cable passing through the cable management plate 6 is wound and wound around the body of the winding rod 4 at a constant speed and tension. The body of the clamping rod 5 is in close contact with the outside of the cable wound by the winding rod 4. The cable management plate 6 ensures that the cable can be guided by the cable arrangement before entering the winding stage, while the body of the clamping rod 5 is always in close contact with the outermost layer of the cable wound on the winding rod 4, which can apply radial pressure to the wound cable. This not only effectively compacts the wound cable coils and prevents the disorder and crossing caused by loosening, but also adaptively moves outward as the radius of the cable coil increases, always maintaining the contact pressure. This ensures that the cable is neatly and tightly arranged on the winding rod 4 with constant tension, eliminating the risk of tangling caused by tension fluctuations or disordered arrangement, and improving the stability of cable winding and unwinding operations.

[0033] A ring-shaped C-shaped guide rail 64 is connected to the bottom of the cable management board 6. A ring-shaped drive belt 63 is movably mounted inside the ring-shaped C-shaped guide rail 64. A continuously variable speed control (CVT) component is installed inside the adjustment drive box 7. The power input end of the CVT component is synchronously connected to the winding rod 4, and the power output end of the CVT component is connected to the ring-shaped drive belt 63. The clamping rod 5 gradually moves as the radius of the cable coil wound by the winding rod 4 increases. A hydraulic synchronization adjustment mechanism is provided between the CVT component and the winding rod 4. The CVT component ensures that the speed of the cable management action is synchronized with the cable winding speed. It can sense in real time the displacement change of the clamping lever 5 as the cable winding radius increases, and convert this mechanical displacement into a hydraulic signal, thereby steplessly adjusting the transmission ratio of the stepless speed regulating component, thus dynamically changing the speed of the ring drive belt 63. As the cable is wound thicker on the winding lever 4, the lateral movement speed of the conductor ring 62 will be reduced accordingly to match the required cable laying stroke for each turn of the cable, ensuring that the cable is always tightly arranged with the best cutting angle. Whether at the beginning or end of winding, the pitch of the cable laying can match the winding speed, eliminating the problem of overlapping or excessive gap caused by the mismatch between the cable laying speed and the winding speed, and further improving the anti-winding effect.

[0034] The cable management plate 6 has a movable slot 61. The belt of the annular drive belt 63 is connected to a conductor ring 62. The conductor ring 62 is fitted onto the cable body and moves synchronously within the movable slot 61 area along with the cable winding path. The movable slot 61 provides a straight path constraint for the reciprocating movement of the conductor ring 62, preventing it from swaying during movement. The conductor ring 62 is fixedly connected to the belt of the annular drive belt 63, so that the lateral movement power of the conductor ring 62 comes directly from the stepless speed regulation component, realizing the linkage between the cable laying action and the winding action. During the winding process, the conductor ring 62 will reciprocate linearly within the limited range of the movable slot 61 at a speed that matches the rotation speed of the winding rod 4 and the current cable diameter, thereby guiding the cable to be arranged tightly and neatly layer by layer on the winding rod 4, ensuring that the cable is accurately positioned and orderly arranged in each turn on the winding rod 4. During the cable release process, it can also guide the cable to be released from the winding rod 4 in a neat layer by layer.

[0035] Example 2

[0036] Improvements based on Example 1:

[0037] like Figures 1 to 7 As shown, it also includes a base plate 1, on which a motor mounting support plate 11, a drive box mounting support plate 12, and an auxiliary support plate 13 are fixedly installed. A constant tension winding motor 14 is fixedly connected to the motor mounting support plate 11. A cable management plate 6 is fixedly connected between the top ends of the drive box mounting support plate 12 and the auxiliary support plate 13. An adjustable drive box 7 is fixedly connected to the side of the drive box mounting support plate 12 away from the auxiliary support plate 13, and the adjustable drive box 7 is connected to the cable management plate 6. The constant tension winding motor 14 is fixed on the motor mounting support plate 11 to ensure the coaxiality of the motor output shaft and the winding rotor 4, reducing the additional load caused by vibration or misalignment. The cable management plate 6 is fixedly connected between the top ends of the drive box mounting support plate 12 and the auxiliary support plate 13, so that the cable management plate 6 can withstand the reaction force generated during the cable winding and unwinding process without deformation or displacement, ensuring the accuracy of the moving trajectory of the conductor ring 62.

[0038] Furthermore, the output end of the constant tension winding motor 14 is coaxially and fixedly connected to the winding rod 4. A drive wheel 41 is coaxially and fixedly sleeved on one end of the winding rod 4 near the constant tension winding motor 14. An active conical rotor 72 (power input end) and a driven conical rotor 73 (power output end) are rotatably connected inside the adjustment drive box 7. The active conical rotor 72 and the driven conical rotor 73 are arranged in a centrally symmetrical manner. A driven wheel 712 is coaxially and fixedly sleeved on the active conical rotor 72. A transmission belt 42 connects the active wheel 41 and the driven wheel 712, driving the winding rod 4... The rotational motion is transmitted to the power input end of the adjustment drive box 7. Since the active rotor 41 is coaxial with the winding rotor 4, its rotational speed completely represents the winding speed. Therefore, the active conical rotor 72 inside the adjustment drive box 7 can obtain a reference rotational speed that is in a fixed proportion to the winding speed. Furthermore, the active conical rotor 72, which serves as the power input end, and the driven conical rotor 73, which serves as the power output end, are rotatably connected inside the adjustment drive box 7. The two are arranged in a centrally symmetrical manner to form a friction transmission interface with stepless speed change. Transmission can be achieved without additional sensors or complex electronic control systems.

[0039] Furthermore, both the drive box mounting support plate 12 and the auxiliary support plate 13 have vertical through slots 15. A slider 16 is slidably disposed in the through slot 15. The two ends of the clamping rod 5 are rotatably connected to the slider 16, so that the clamping rod 5 can move away from the axis of the winding rod 4 under the guidance of the through slot 15 as the diameter of the winding cable increases. At the same time, the clamping rod 5 is rotatably connected to the slider 16, ensuring that when the clamping rod 5 is in close contact with the rotating cable coil surface, it can passively rotate with it, converting sliding friction into rolling friction, reducing the wear of the clamping rod 5 and the cable surface, and avoiding interference with the follow-up displacement of the clamping rod 5 due to frictional resistance, effectively preventing the winding cable from becoming loose and disordered.

[0040] Furthermore, a movable push rod 17 is movably disposed within the through groove 15 of the drive box mounting support plate 12. The top end of the movable push rod 17 is inserted into the movable cavity 18. A limit link 110 is fixedly connected within the through groove 15 of the auxiliary support plate 13. The rod body of the limit link 110 is movably sleeved with another slider 16. The drive box mounting support plate 12 has a movable cavity 18. The bottom end of the movable push rod 17 is fixedly connected to one of the sliders 16. Both the movable push rod 17 and the limit link 110 are fitted with a rotating rod return spring 19 on their rod bodies within the through groove 15. When locked... As the cable reel diameter increases, the rotating rod 5 moves outward, driving the movable push rod 17 into the movable cavity 18 via the slider 16. The advancement of the movable push rod 17 compresses the hydraulic oil, generating an oil pressure change proportional to the displacement. This change is transmitted through the hydraulic transmission pipe 713 to the hydraulic drive outer pipe 71 in the adjustment drive box 7. Simultaneously, the limiting linkage 110 provides guidance and limitation for the movement of the clamping rotating rod 5. When the cable is released and the reel diameter decreases, the rotating rod return spring 19 provides a restoring force, pushing the clamping rotating rod 5 and the movable push rod 17 back, and enabling the hydraulic transmission to respond in the reverse direction.

[0041] like Figure 8 As shown, the outer rail of the annular C-shaped guide rail 64 has a notch 65, and the inner rail of the annular C-shaped guide rail 64 has several rolling shafts 66 embedded in it. The belt of the annular drive belt 63 rolls and fits against the rolling shafts 66. The rolling shafts 66 change the friction mode between the annular drive belt 63 and the guide rail from sliding friction to rolling friction, reducing the coefficient of friction. This makes the movement of the annular drive belt 63 smoother and avoids crawling or shaking caused by uneven friction, thereby ensuring the stability of the movement of the guide ring 62.

[0042] like Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, the continuously variable speed control assembly also includes a hydraulic drive outer tube 71, a friction transmission wheel 74, and a hydraulic telescopic tube 79. The hydraulic drive outer tube 71 is fixedly connected to the body of the regulating drive box 7. The hydraulic telescopic tube 79 is movably sleeved inside the hydraulic drive outer tube 71. The friction transmission wheel 74 is coaxially fixedly sleeved on the end of the hydraulic telescopic tube 79 located outside the hydraulic drive outer tube 71, and the friction transmission wheel 74 is tightly attached between the cone surfaces of the driving conical rotor 72 and the driven conical rotor 73. A piston 710 is coaxially fixedly connected to the end of the hydraulic telescopic tube 79 located inside the hydraulic drive outer tube 71. A hydraulic delivery pipe 713 connects the hydraulic drive outer tube 71 and the movable cavity 18. The hydraulic drive outer tube 71, the movable cavity 18, and the hydraulic delivery pipe 713 are all filled with hydraulic oil. A limit rod 75 is movably inserted inside the hydraulic telescopic tube 79. The outer end of the limit rod 75 is fixedly connected to the regulating drive box 7. The transmission wheel 74 presses against the conical surfaces of the driving conical rotor 72 and the driven conical rotor 73. By changing the radial position of the friction transmission wheel 74, its contact radius with the driving and driven conical rotors 72 and 73 can be changed, thereby achieving stepless speed change. The power source for changing the radial position of the friction transmission wheel 74 is the piston 710 at the inner end of the hydraulic telescopic tube 79, which is connected to the hydraulic oil from the movable chamber 18. When the cable reel diameter increases, the movable push rod 17 compresses the hydraulic oil in the movable chamber 18, increasing the oil pressure. This pressure is transmitted to the hydraulic drive outer tube 71 through the hydraulic delivery pipe 713, pushing the piston 710 and the hydraulic telescopic tube 79 to extend outward, thereby driving the friction transmission wheel 74 to achieve deceleration. Conversely, when the reel diameter decreases, the oil pressure decreases, and the friction transmission wheel 74 moves in the opposite direction to achieve speed increase. The limit rod 75 ensures the accuracy of the axial movement of the hydraulic telescopic tube 79 and ensures the stability of the position of the friction transmission wheel 74.

[0043] Furthermore, the driven conical rotor 73 is coaxially fixedly connected to the driving conical gear 76 located outside the adjustment drive box 7. The lower plate of the cable management plate 6 is rotatably connected to the driven conical gear 77 and the friction drive disc 78. The driven conical gear 77 and the friction drive disc 78 are coaxially fixedly connected, and the driven conical gear 77 meshes with the driving conical gear 76. Part of the wheel body of the friction drive disc 78 passes through the notch 65 and is tightly fitted with the belt body of the annular drive belt 63. The driving conical gear 76 and the driven conical gear 77 mesh to form a vertical transmission bevel gear pair, so that the rotational power output from the horizontal adjustment drive box 7 can be transmitted to the vertical friction drive disc 78. The friction drive disc 78 has an overload protection function. When the annular drive belt 63 is stuck, the friction drive disc 78 can slip to avoid damage to the motor or transmission components. The friction drive disc 78 drives the annular drive belt 63 to make a closed-loop motion along the annular C-shaped guide rail 64, thereby driving the wire ring 62 to achieve reciprocating cable arrangement.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the base plate 1 can also be detachably connected to a cable housing 2 and a motor housing 3. The cable housing 2 covers the outside of the cable winding area, and the motor housing 3 covers the outside of the installation area of ​​the constant tension winding motor 14. The cable housing 2 has a cable through groove 21. The position of the cable through groove 21 corresponds to the position of the movable groove 61 opened on the cable management plate 6. The cable housing 2 and the motor housing 3 can play a good protective role. The cable through groove 21 plays a preliminary limiting and guiding role in the direction of cable entry and exit.

[0045] Working principle: After the constant tension winding motor 14 starts, it directly drives the winding rotor 4 to wind at a constant tension at a uniform speed. At the same time, the driving wheel 41 on the winding rotor 4 drives the driven wheel 712 in the adjusting drive box 7 to rotate through the transmission belt 42, thereby enabling the driving conical rotor 72 to obtain a speed proportional to that of the winding rotor 4. A friction drive wheel 74 is pressed between the driving conical rotor 72 and the driven conical rotor 73. The friction drive wheel 74 is fixedly sleeved on one end of the hydraulic telescopic tube 79. The hydraulic telescopic tube 79 is movably sleeved in the hydraulic drive outer tube 71, and a piston 710 is coaxially fixed at its inner end. The driving conical rotor 72 drives the friction drive wheel 74 to rotate through friction, thereby driving the driven conical rotor 73 to rotate. 3. Rotation: The rotational speed of the driven conical rotor 73 depends on the radial position of the friction drive wheel 74 on the conical surface. The driven conical rotor 73 is coaxially connected to the driving conical gear 76, which meshes with the driven conical gear 77. The driven conical gear 77 is coaxially connected to the friction drive disk 78, which passes through the notch 65 of the annular C-shaped guide rail 64 and is in close contact with the annular drive belt 63, thereby driving the annular drive belt 63 to make a closed-loop motion along the annular C-shaped guide rail 64. The annular drive belt 63 is connected to a wire ring 62, which is sleeved on the cable and passes through the movable slot 61 of the cable management plate 6. It moves in a reciprocating linear motion with the annular drive belt 63, guiding the cable to be evenly wound on the winding rod 4.

[0046] The clamping rod 5 is in close contact with the outermost layer of the cable on the winding rod 4, and its two ends are rotatably connected to the slider 16 in the through groove 15. When the radius of the cable coil increases, the clamping rod 5 is pushed outward, causing the slider 16 to slide. The slider 16 on one side of the drive box mounting support plate 12 is fixed with a movable push rod 17. The top of the movable push rod 17 is inserted into the movable cavity 18 and compresses the hydraulic oil. The oil pressure is transmitted to the piston 710 through the hydraulic transmission pipe 713, which pushes the hydraulic telescopic pipe 79 and the friction transmission wheel 74 to move simultaneously. At this time, the friction transmission wheel 74 moves from the large-diameter cone bottom to the small-diameter cone top of the active conical rotor 72. The contact radius between the friction transmission wheel 74 and the active conical rotor 72 decreases, and the friction... The transmission wheel 74 moves from the small-diameter cone apex to the large-diameter cone bottom of the driven conical rotor 73. The contact radius between the friction transmission wheel 74 and the driven conical rotor 73 increases. According to the continuously variable transmission ratio relationship: the output speed of the driven conical rotor 73 = the input speed of the driving conical rotor 72 × (driving side contact radius / driven side contact radius), the driving side contact radius decreases and the driven side contact radius increases, the transmission ratio decreases, thereby reducing the output speed of the driven conical rotor 73, and thus slowing down the lateral movement speed of the conductor ring 62 to adapt to the increased cable reel diameter. Conversely, when the cable coil radius decreases, the return spring 19 pushes the clamping rod 5 inward, the movable push rod 17 retracts, the oil pressure decreases, the contact radius between the friction drive wheel 74 and the active conical rotor 72 increases, and the contact radius between the friction drive wheel 74 and the driven conical rotor 73 decreases. That is, the contact radius on the active side increases and the contact radius on the driven side decreases, the transmission ratio increases, the output speed of the driven conical rotor 73 increases, and the speed of the wire ring 62 increases to adapt to the reduced coil diameter. This allows the moving speed of the wire ring 62 to be adjusted in real time and steplessly with the continuous change of the cable coil diameter, ensuring that the cable laying speed always matches the winding speed, achieving neat cable arrangement and effectively preventing tangling.
