Because they are circular and divergent, the cable will be wound around and around along the shape of the arc-shaped baffles, so that the spacing between each layer of the cable during the rolling process is more uniform; If the equipment shakes or the cable tension changes during the reeling process, the cable will easily slip from the reeling position without the curved baffle. The curved baffle can effectively avoid this situation and ensure the neatness and stability of the cable reeling. 2. In the present invention, if there is no good limiting measure for the cable, it is easy to get tangled or tangled during the winding process. The two pairs of driven clamping wheels can moderately clamp the cable to control the direction of the cable; they keep the cable in a certain tension and direction during the winding process to avoid the cable itself from crossing or twisting, which causes excessive internal stress and affects the long-term performance; the driven clamping wheels can adapt to cables of different diameters by adjusting the spacing between the clamping wheels or using elastic materials, thereby improving the flexibility of the device; 3. If the cable is wound at only one fixed position, it is easy to cause local accumulation, resulting in an irregular winding shape. In the present invention, by controlling the cable to move back and forth left and right, the cable can be wound more evenly on several arc-shaped baffles; By moving back and forth, the cables can be evenly spread layer by layer on the structure formed by several arc-shaped baffles, making full use of the space, so that more cables can be rolled up, improving the efficiency and compactness of the rolling up. At the same time, the uniform winding also ensures that the shape of the rolled cable is regular, which is convenient for subsequent transportation, storage and use. In summary, the present invention can improve the compactness, uniformity, safety and flexibility of cable winding, while being able to better control the tension of the cable and meet the requirements for efficient winding of power cables of different specifications.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Embodiment 1: This embodiment provides a power cable winding device, see Figure 1-8 , including a bottom plate 1, wherein moving wheels are installed at the four corners of the bottom surface of the bottom plate 1, a pair of symmetrically distributed side plates 11 are fixedly arranged on the rear side of the top surface of the bottom plate 1, a circular through hole is opened on the top of each side plate 11, a rotating drum 12 is rotatably engaged inside each circular through hole, a through-distributed hollow disk 13 is fixedly arranged at the inner end of each rotating drum 12, and a through-distributed hollow cylinder 2 is fixedly arranged between the pair of hollow disks 13, and a plurality of circularly distributed arc baffles 24 are arranged on the outer surface of the hollow cylinder 2, and the plurality of arc baffles 24 are evenly arranged outward in a circular divergent shape; A pair of trapezoidal plates 3 are fixedly provided on the front side of the top of the bottom plate 1, an open box 31 with an open front is fixedly provided between the top ends of the pair of trapezoidal plates 3, a U-shaped slide plate 32 slidingly distributed left and right is engaged in the middle of the front of the open box 31, an L-shaped plate 4 is fixedly provided on the top surface of the U-shaped slide plate 32, two pairs of driven card wheels 45 are installed in the L-shaped plate 4, and cables 46 are wound around the outer surfaces of the plurality of arc-shaped baffles 24, and the front end of the cable 46 extends forward and is inserted between the two pairs of driven card wheels 45; When the cable 46 is rolled up, the arc-shaped baffles 24 are evenly arranged in a circular divergent shape to form a ring-like structure, and the cable 46 is wound around the outer surface of the arc-shaped baffle 24, and the arc-shaped baffle 24 can block the cable 46; The driven clamping wheel 45 clamps the cable 46 relatively gently, and its surface is usually made of rubber or other soft materials. During the clamping and limiting process, these soft materials come into contact with the surface of the cable 46 to avoid scratches or wear on the surface of the cable 46.

[0019] Embodiment 2: Based on Embodiment 1, this embodiment also includes the following contents: like Figure 5 and Figure 6 As shown, the inner side of the hollow disk 13 is provided with a plurality of oval sliding holes 14 distributed in a circular shape, and a T-shaped slider 25 is slidably engaged in the middle of each oval sliding hole 14, and the inner end of the T-shaped slider 25 is oval and the outer end is ring-shaped. The inner side of each arc-shaped baffle 24 is fixed with a horizontal limit axis 23 distributed horizontally, and both ends of each limit axis 23 are rotatably inserted into the corresponding T-shaped slider 25; A concentrically distributed annular rail 15 is fixed on the inner ring surface of the hollow disk 13, and a concentrically distributed concentric disk 16 is rotatably engaged in the annular rail 15. The concentric disk 16 is provided with a plurality of circularly distributed arc-shaped pin holes 17. Both ends of each limiting horizontal axis 23 are slidably inserted in the corresponding arc-shaped pin holes 17. Under the limiting effect formed by the ends of the limiting horizontal axis 23 and the arc-shaped pin holes 17, the T-shaped slider 25 can be driven to slide along the elliptical sliding hole 14, thereby driving the limiting horizontal axis 23 and the arc-shaped baffle 24 to slide synchronously, so that the plurality of arc-shaped baffles 24 are translated outward to a suitable position. The hollow cylinder 2 is provided with a concentrically distributed fixed shaft 21, and the two ends of the fixed shaft 21 pass through a pair of concentric disks 16 and are fixedly connected to the pair of concentric disks 16, and the two ends of the fixed shaft 21 are rotatably inserted on the pair of rotating cylinders 12; The right end of the fixed shaft 21 passes through the corresponding rotating cylinder 12 and is sleeved with a concentrically fixed eccentric disk 22. A hexagonal knob is fixed in the middle of the outer side of the eccentric disk 22. Rotating the hexagonal knob can drive the eccentric disk 22, the fixed shaft 21, and a pair of concentric disks 16 to rotate along the annular clamping rail 15. One side of the eccentric disk 22 is convex and has a threaded hole. A threaded bolt is inserted into the threaded hole. Tightening the bolt can make the inner end of the bolt abut against the corresponding rotating cylinder 12. The cable 46 will generate friction with the winding device during the winding process. The outer surface of the arc-shaped baffle 24 can serve as a support for the cable 46, reducing the direct contact between the cable 46 and other hard components. Wrapping around the outer surface of the arc-shaped baffle 24 can enable the cable 46 to slide and wind on the relatively soft surface of the arc-shaped baffle 24, thereby playing a role in buffering and protecting the surface of the cable 46.

[0020] Embodiment 3: Based on Embodiment 2, this embodiment also includes the following contents: like Figure 7 and Figure 8 As shown, two pairs of torsion shafts 41 are rotatably inserted into the inner side of the L-shaped plate 4, and the outer end of each torsion shaft 41 is sleeved with a concentric fixed notch gear 43, and the middle section of each torsion shaft 41 is sleeved with a torsion spring 42, and the two ends of each torsion spring 42 are respectively fixed to the L-shaped plate 4 and the notch gear 43; A pair of adjacent notched gears 43 are meshed and connected, and a driven swing arm 44 is fixedly provided at the notched portion of each notched gear 43, and a driven shaft is rotatably inserted at the outer end of each driven swing arm 44, and each driven clamping wheel 45 is fixedly sleeved on the corresponding driven shaft. The torsion action of the torsion spring 42 cooperates with the mutual meshing action of the notched gears 43 to drive the torsion shaft 41, the notched gear 43, the driven swing arm 44 and the driven clamping wheel 45 to rotate inward along the torsion shaft 41, so that the two pairs of driven clamping wheels 45 always abut against the cable 46; Because the cable 46 may be displaced when being wound due to its own elasticity, tension changes or slight vibration of the equipment, the position of the cable 46 can be effectively fixed by clamping and limiting the cable 46 with two pairs of driven clamping wheels 45; When the cable 46 is wound up at a high speed, its inertia may cause it to swing left and right in the horizontal direction, and the clamping effect of the driven clamping wheel 45 acts like a track, allowing the cable 46 to be wound along a predetermined route at all times, ensuring that the cable 46 can be accurately wound around the winding device, and preventing the cable 46 from being wound around other components and causing damage; A pair of linkage shafts 34 are rotatably inserted on both sides of the open box 31, and the front end of each linkage shaft 34 is sleeved with a concentrically fixed linkage pulley, and a linkage belt 35 for transmission connection is sleeved between the pair of linkage pulleys, and a limiting pin 36 is fixed on the outer surface of the linkage belt 35, and an elliptical pin hole 33 is opened on the front of the U-shaped slide plate 32, and the front end of the limiting pin 36 is slidably inserted in the elliptical pin hole 33. Under the limiting action formed by the limiting pin 36 and the elliptical pin hole 33, the U-shaped slide plate 32 and the L-shaped plate 4 can be driven to slide back and forth along the open box 31, and the cables 46 can be evenly distributed on a number of arc-shaped baffles 24; when the cables 46 are evenly wound during the winding process, it can prevent the cables 46 from being accumulated too thickly in some places.

[0021] Embodiment 4: Based on Embodiment 3, this embodiment also includes the following contents: like Figure 5 and Figure 8 As shown, a square through hole is provided on the top of the trapezoidal plate 3 located on the left side, and a servo motor 26 with an output end facing outward is installed inside the square through hole, and a first small-diameter pulley is sleeved on the motor shaft end of the servo motor 26, which is concentrically fixed. The motor shaft of the servo motor 26 can drive the first small-diameter pulley to rotate synchronously, and a first large-diameter pulley is sleeved on the outer end of the rotating drum 12 located on the left side, which is concentrically fixed. The first small-diameter pulley is connected to the first large-diameter pulley through a first belt 27. The first small-diameter pulley can drive the first large-diameter pulley, a pair of rotating drums 12, a pair of hollow disks 13, the hollow drum 2, a plurality of arc-shaped baffles 24, and a second large-diameter pulley to rotate through the first belt 27, and synchronously drives the cable 46 to be wound along the plurality of arc-shaped baffles 24; The rear end of the linkage shaft 34 on the right side penetrates the open box 31 and is sleeved with a concentrically fixed worm wheel 37. The top end of the trapezoidal plate 3 on the right side is rotatably inserted with a positioning shaft 28 that is distributed and penetrates horizontally. The inner end of the positioning shaft 28 is fixed with a worm 38. The worm 38 is meshed and connected with the worm wheel 37. The worm 38 can mesh and drive the worm wheel 37, a pair of linkage shafts 34, a pair of linkage pulleys, a linkage belt 35, and a limit pin shaft 36 to rotate. The outer end of the positioning shaft 28 is sleeved with a second small diameter pulley that is concentrically fixed, and the outer end of the rotating drum 12 located on the right side is sleeved with a second large diameter pulley that is concentrically fixed. The second large diameter pulley is connected to the second small diameter pulley through a second belt 29. The second large diameter pulley can drive the second small diameter pulley, the positioning shaft 28, and the worm 38 to rotate through the second belt 29.

[0022] Specifically, the working principle and operation method of the present invention are as follows: Step 1: Loosen the bolts and rotate the hexagonal knob to drive the eccentric disk 22, the fixed shaft 21, and a pair of concentric disks 16 to rotate along the annular rail 15. Under the limiting effect formed by the end of the limiting horizontal shaft 23 and the arc-shaped pin hole 17, the T-shaped slider 25 is driven to slide along the elliptical sliding hole 14, thereby driving the limiting horizontal shaft 23 and the arc-shaped baffle 24 to slide synchronously, so that the arc-shaped baffles 24 are translated outward to a suitable position, and then the bolts are tightened so that the inner end of the bolts abuts against the corresponding rotating drum 12; Step 2: When the cable 46 is wound up, one end of the cable 46 is passed through the two pairs of driven clamping wheels 45 and fixed on the arc-shaped baffle 24. The torsion of the torsion spring 42 cooperates with the mutual meshing of the notched gear 43 to drive the torsion shaft 41, the notched gear 43, the driven swing arm 44 and the driven clamping wheel 45 to rotate inward along the torsion shaft 41, so that the two pairs of driven clamping wheels 45 always rest on the cable 46. Step 3: Under the driving action of the servo motor 26, the motor shaft of the servo motor 26 drives the first small-diameter pulley to rotate synchronously, and the first small-diameter pulley drives the first large-diameter pulley, a pair of rotating drums 12, a pair of hollow disks 13, the hollow drum 2, a plurality of arc-shaped baffles 24, and the second large-diameter pulley to rotate through the first belt 27, and synchronously drives the cable 46 to be wound along the plurality of arc-shaped baffles 24; Step four, the second large diameter pulley drives the second small diameter pulley, the positioning shaft 28, and the worm 38 to rotate through the second belt 29, and the worm 38 engages to drive the worm wheel 37, a pair of linkage shafts 34, a pair of linkage pulleys, the linkage belt 35, and the limit pin 36 to rotate.
