The first is the selection of raw materials, including conductor materials such as copper, aluminum, etc., and various insulating materials. Then, through a specific production process, the conductor and the insulating material are combined to form a cable with good insulation and conductivity.

Although it is inexpensive, the operator only needs to step on the foot pedal to control the work of the pay-off stand.

However, cable reels with different inner diameters mean that the support structure of the pay-off stand needs to be able to be flexibly adjusted to adapt to various sizes.

[0015] An insulated cable includes a conductor, an insulating layer, and a shielding layer. The conductor is the main conductive part of the cable and is responsible for transmitting electrical energy and signals. The conductor is made of either copper or aluminum. The insulating layer is used to isolate the conductor to prevent electric shock and short circuit caused by current leakage or accidental contact. The shielding layer can reduce the interference of the electromagnetic field around the cable and enhance the anti-interference ability of the cable.

[0016] The above embodiments of the present invention can achieve the following beneficial effects:

[0017] By setting a tension and relaxation placement structure, when the two fixed frames on both sides move toward each other to drive the four vertical poles to move, the four connecting rods drive the four arc blocks to approach each other, so that the distance between the four rotating rods is reduced, and the cable reel with a smaller inner diameter can be supported and placed. Therefore, when the two fixed frames on both sides move toward each other, the four rotating rods automatically shrink to adapt to the cable reel with a smaller inner diameter, thereby expanding the adaptability of the device to cable reels with different inner diameters and improving the flexibility and practicality of the equipment;

[0018] By setting four universal wheels, the two fixing frames 2 can be effectively supported. During the operation of the equipment, the fixing frames 2 and the components connected to the fixing frames 2 are no longer supported solely by the two double-threaded screws 1, which greatly reduces the workload of the double-threaded screws 1. By sharing the support pressure, the service life of the double-threaded screws 1 is increased, and the maintenance cost and downtime of the equipment are reduced. At the same time, when the two fixing frames 2 move toward each other, the universal wheels can make the movement of the fixing frames 2 more stable. The flexibility of the universal wheels enables the fixing frames 2 to adjust their positions smoothly during the movement, avoiding shaking and bumping, and ensuring the reliability and safety of the equipment operation.

[0019] By setting a supporting structure, when the vertical pole slides, the cooperation of the sliding frame and the sliding groove and the synergistic effect of the rotating connecting rod and the supporting sliding rod can obtain double support. The sliding of the sliding frame in the sliding groove provides a stable supporting point for the vertical pole, ensuring that the vertical pole moves smoothly and reliably in the horizontal direction. At the same time, the combination of the rotating connecting rod and the supporting sliding rod provides another important supporting point for the vertical pole. When the vertical pole moves, the rotating connecting rod rotates along the supporting sliding rod, making the vertical pole more stable during the movement, greatly improving the overall stability of the equipment, and ensuring the safety of the cable drum during the support placement and processing. Whether it is during the installation, disassembly or processing of the cable drum, the vertical pole can maintain a stable state, providing reliable guarantee for the production and processing of the cable, improving the production quality and efficiency, and no matter what position the vertical pole is in, the vertical pole can be supported by the rotating connection;

[0020] By setting a limiting structure, four sleeve rods, four limiting sliding frames, eight connecting blocks, four telescopic rotating rods and a disc, the four rotating rods and four arc blocks are respectively formed into a whole. The arc blocks can only move along the contraction trajectory of the limiting sliding frames and the rotation trajectory of the telescopic rotating rods, which effectively prevents the four arc blocks from shifting in position when they move close to each other, ensuring that the supporting points of the four rotating rods for the cable reel are always in the correct position, improving the stability and reliability of the support. Since the four arc blocks form a whole, the stability of the structure is greatly enhanced, avoiding the situation where the arc blocks move downward due to their own weight, and ensuring that in the process of supporting and placing the cable reel, the arc blocks always remain in the correct position and will not produce displacement changes due to their own gravity, thereby providing continuous and stable support for the cable reel.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figure 1 - Figure 7As shown, an insulated cable processing device comprises two fixed frames 1, two fixed frames 2 are arranged between the two fixed frames 1, the tops of the two fixed frames 2 are fixedly connected with fixed blocks 6 near the front and rear parts, the front and rear parts between the two fixed frames 1 are rotatably connected with double-threaded screw rods 7, one end of the two double-threaded screw rods 7 respectively penetrate the side of the fixed frame 1 on one side and are fixedly connected with pulleys 8, a belt is sleeved between the two pulleys 8, a mounting frame is fixedly connected with the front part of the side of the fixed frame 1 on one side, a motor 9 is fixedly connected with the side of the mounting frame, slide grooves 14 are provided on both sides of the two fixed frames 2, the fixed frame 2 is slidably connected with a sliding frame 13 through the slide grooves 14 on both sides, the double-threaded screw rod 7 is threadedly connected with the fixed block 6, the top of the sliding frame 13 is fixedly connected with a vertical rod 12, and a tensioning and relaxing placement structure 4 is provided between the two vertical rods 12 near the front and between the two vertical rods 12 near the back;

[0031] The tensioning and relaxing placement structure 4 includes four rotating rods 23, four arc blocks 19 are arranged between two vertical rods 12, the outer surface of the arc block 19 is fixedly connected with a connecting block 1 20, the side of the vertical rod 12 is fixedly connected with a connecting block 21 near the top and the bottom, a connecting rod 22 is rotatably connected between the connecting block 1 20 and the connecting block 2 21, the rotating rod 23 is rotatably connected to the front part of the arc block 19, and one end of the rotating rod 23 passes through the rear part of the arc block 19 and is fixedly connected to the limiting block 1 24;

[0032] Start the motor 19 to drive the pulley 8 at the front to rotate, and then drive the pulley 8 at the rear to rotate through the belt, thereby driving the two double-threaded screws 17 to rotate synchronously, and then the two fixed frames 2 move toward each other, and then drive the four vertical poles 12 on both sides to move toward each other, thereby changing the distance between the two fixed frames 2, so that no matter how large the outer diameter of the cable reel is, it can be placed between the two fixed frames 2;

[0033] When the two fixed frames 2 move toward each other and drive the four vertical poles 12 on both sides to move together, the four connecting rods 22 at the front also move, thereby driving the four arc blocks 19 at the front to approach each other, thereby reducing the distance between the four rotating rods 23, and then the cable reels with smaller inner diameters can be supported and placed by the four rotating rods 23. The moving trajectory of the four connecting rods 22 at the rear is the same as above.

[0034] In this embodiment, a placement block 11 is provided at the front and rear between the two fixed frames 2, a placement block 2 is provided between the two sliding frames 13 at the front and the two sliding frames 13 at the rear, a connecting telescopic plate 10 is fixedly connected between the two sides of the placement block 11 and the two fixed frames 2, a connecting telescopic plate 2 is fixedly connected between the two sides of the placement block 2 and the two sliding frames 13, a double-threaded screw rod 2 15 is rotatably connected between the two placement blocks 11, the double-threaded screw rod 2 15 is threadedly connected to the placement block 2, and a motor 2 16 is fixedly connected to the front of the placement block 11 at the front;

[0035] Starting motor 2 16 drives double-threaded screw 2 15 to rotate, and then drives the two sliding frames 13 at the front and the two sliding frames 13 at the rear to slide toward each other along the four slide grooves 14 through two placement blocks 2 and four connecting telescopic plates 2, and then drives the two vertical poles 12 at the front and the two vertical poles 12 at the rear to slide toward each other, thereby reducing the distance between the front and rear pairs of vertical poles 12. Therefore, it can not only adapt to cable reels of different lengths, but also automatically insert multiple rotating rods 23 into the inner circle of the cable reel to perform support placement operations.

[0036] In this embodiment, the output shaft of motor 1 9 passes through the side of the mounting frame and is fixedly connected to the pulley 8 at the front, and the output shaft of motor 2 16 passes through the placement block 1 11 at the front and is fixedly connected to one end of the double-threaded screw 2 15.

[0037] In this embodiment, the bottoms of the four fixed blocks 6 are fixedly connected with universal wheels 17, and the bottoms of the two fixed frames 1 are fixedly connected with legs 18 near the front and rear parts, and the bottoms of the legs 18 are at the same height as the bottoms of the universal wheels 17;

[0038] The four universal wheels 17 can support the two fixing frames 2, so that the fixing frames 2 and the components connected to the fixing frames 2 do not need to rely solely on the two double-threaded screw rods 17 for support, thereby reducing the workload of the two double-threaded screw rods 17 and increasing the service life of the double-threaded screw rods 17. In addition, when the two fixing frames 2 move toward each other, the four universal wheels 17 can also make the movement of the fixing frames 2 more stable.

[0039] In this embodiment, a support structure 3 is provided at the front and rear parts of the two fixed frames 2, and the support structure 3 includes four rotating support rods 26. The top of the fixed frame 22 is fixedly connected to the front and rear parts with a connecting block 3 25, one end of the rotating support rod 26 is rotatably connected to the connecting block 3 25, and the tops of the four vertical rods 12 are rotatably connected to a rotating connecting rod 29, and a supporting slide rod 27 is penetrated and connected between the four rotating connecting rods 29, and the two ends of the supporting slide rod 27 respectively penetrate the front and rear parts of the four rotating support rods 26 and are fixedly connected to the limiting block 2 28;

[0040] When the two vertical rods 12 at the front and the two vertical rods 12 at the rear move toward each other, the two rotating connecting rods 29 at the front and the two rotating connecting rods 29 at the rear move toward each other along the supporting slide rod 27. Therefore, when the vertical rod 12 slides, it can not only slide through the support point of the sliding frame 13 and the slide groove 14, but also be supported and slid by the rotating connecting rod 29 and the supporting slide rod 27, so that the vertical rod 12 is more stable during the movement;

[0041] The two fixed frames 2 move toward each other and drive the four vertical poles 12 on both sides to move toward each other. At the same time, the two rotating support rods 26 at the front rotate synchronously, and the distance between one ends of the two rotating support rods 26 at the front is shortened. Therefore, its supporting slide bar 27 will be lifted. The movement trajectory of the two rotating support rods 26 at the rear is consistent with the above. When the supporting slide bar 27 rises, it will drive the four rotating connecting rods 29 to rotate together. Although the rotating connecting rod 29 rotates, it will not support the slide bar 27 to separate. Therefore, even after the vertical poles 12 on both sides move toward each other, the supporting slide bar 27 can still support the top of the vertical pole 12.

[0042] In this embodiment, one end of the four rotating rods 23 near the front and one end of the four rotating rods 23 near the rear are both provided with a limiting structure 5, the limiting structure 5 comprises a disc 30, the disc 30 is arranged between the four rotating rods 23 near one end, the interior of each rotating rod 23 is rotatably connected with a sleeve rod 31, the interior of the disc 30 passes through the outer surface and is symmetrically slidably connected with four limiting sliding frames 32, one end of the sleeve rod 31 passes through the front of the limiting sliding frame 32 and is fixedly connected with a limiting block three 33, the rear of the disc 30 is symmetrically fixedly connected with four connecting blocks four 34 at the center position, and the front of the four arc blocks 19 is also fixedly connected with a connecting block four 34 at the center position, and a telescopic rotating rod 35 is rotatably connected between the connecting block four 34 located at the front of the arc block 19 and the connecting block four 34 located at the rear of the disc 30;

[0043] When the four rotating rods 23 move and retract, the four limit sliding frames 32 are driven to retract and slide through the four sleeve rods 31. When the four arc blocks 19 retract and move, the connecting blocks 34 connected to the arc blocks 19 are driven to move together, thereby driving the four telescopic rotating rods 35 to rotate and retract.

[0044] The four sleeve rods 31, the four limit sliding frames 32, the eight connecting blocks 34, the four telescopic rotating rods 35 and the disc 30 form the four rotating rods 23 and the four arc blocks 19 into a whole, which not only makes the arc blocks 19 move only along the contraction trajectory of the limit sliding frames 32 and the rotation trajectory of the telescopic rotating rods 35, thereby preventing the four arc blocks 19 from being offset when moving closer to each other, but also because the four arc blocks 19 form a whole, the situation in which the arc blocks 19 move downward due to their own weight is avoided, so that the cable reel can be supported and placed more stably.

[0045] In this embodiment, the diameter of the arc block 19 is greater than the diameter of the disk 30 , and the diameter of the limit block 33 is consistent with the diameter of the rotating rod 23 .

[0046] In this embodiment, the inclination angle of the limit sliding frame 32 is consistent with the inclination angle of the telescopic rotating rod 35, and the maximum sliding distance of the limit sliding frame 32 is consistent with the distance between two arc blocks 19 located on the same diagonal line.

[0047] An insulated cable includes a conductor, an insulating layer, and a shielding layer. The conductor is the main conductive part of the cable, responsible for transmitting electrical energy and signals. The conductor is made of copper or aluminum. The function of the insulating layer is to isolate the conductor to prevent electric shock and short circuit caused by current leakage or accidental contact. The shielding layer can reduce the interference of the electromagnetic field around the cable and enhance the cable's anti-interference ability.

[0048] It should be noted that the present invention is an insulated cable and a processing device thereof. When in use, the motor 9 is started to drive the pulley 8 at the front to rotate, and then the pulley 8 at the rear is driven to rotate through the belt, thereby driving the two double-threaded screws 7 to rotate synchronously, and then the two fixed frames 2 move toward each other, and then drive the four vertical poles 12 on both sides to move toward each other, thereby changing the distance between the two fixed frames 2, so that no matter how large the outer diameter of the cable reel is, it can be placed between the two fixed frames 2;

[0049] When the two fixing frames 2 move toward each other and drive the four vertical poles 12 on both sides to move together, the four connecting rods 22 at the front part all move, thereby driving the four arc-shaped blocks 19 at the front part to approach each other, thereby reducing the distance between the four rotating rods 23, and then the cable reels with smaller inner diameters can be supported and placed by the four rotating rods 23. The moving trajectory of the four connecting rods 22 at the rear part is the same as above.

[0050] When the four rotating rods 23 at the front and the four rotating rods 23 at the rear are inserted into the inner ring of the cable drum, one end of the cable can be connected to the cable processing equipment, for example, one end of the cable can be connected to the steel belt armoring device, and the steel belt is wound around the outer surface of the cable, providing a strong outer protective layer for the cable, which can effectively resist external mechanical pressure, impact, extrusion and other external forces;

[0051] The starting motor 2 16 drives the double-threaded screw rod 2 15 to rotate, and then drives the two sliding frames 13 at the front and the two sliding frames 13 at the rear to slide toward each other along the four slide grooves 14 through the two placement blocks 2 and the four connecting telescopic plates 2, and then drives the two vertical poles 12 at the front and the two vertical poles 12 at the rear to slide toward each other, thereby reducing the distance between the front and rear pairs of vertical poles 12. Therefore, it can not only adapt to cable reels of different lengths, but also automatically insert multiple rotating rods 23 into the inner circle of the cable reel to perform support placement operations;

[0052] The four universal wheels 17 can support the two fixing frames 2, so that the fixing frames 2 and the components connected to the fixing frames 2 do not need to rely on the two double-threaded screw rods 17 for support, thereby reducing the workload of the two double-threaded screw rods 17 and increasing the service life of the double-threaded screw rods 17. In addition, when the two fixing frames 2 move toward each other, the four universal wheels 17 can also make the movement of the fixing frames 2 more stable.

[0053] When the two vertical rods 12 at the front and the two vertical rods 12 at the rear move toward each other, the two rotating connecting rods 29 at the front and the two rotating connecting rods 29 at the rear move toward each other along the supporting slide rod 27. Therefore, when the vertical rod 12 slides, it can not only slide through the support point of the sliding frame 13 and the slide groove 14, but also be supported and slid by the rotating connecting rod 29 and the supporting slide rod 27, so that the vertical rod 12 is more stable during the movement;

[0054] The two fixing frames 2 move toward each other, driving the four vertical poles 12 on both sides to move toward each other. At the same time, the two rotating support rods 26 on the front part rotate synchronously, and the distance between one ends of the two rotating support rods 26 on the front part is shortened. Therefore, the support slide bar 27 will be lifted, and the movement trajectory of the two rotating support rods 26 on the rear part is consistent with the above. When the support slide bar 27 rises, it will drive the four rotating connecting rods 29 to rotate together. Although the rotating connecting rod 29 rotates, it will not support the slide bar 27 to separate. Therefore, even after the vertical poles 12 on both sides move toward each other, the support slide bar 27 can still support the top of the vertical pole 12;

[0055] When the four rotating rods 23 move and retract, the four limit sliding frames 32 are driven to retract and slide through the four sleeve rods 31. When the four arc blocks 19 retract and move, the connecting blocks 34 connected to the arc blocks 19 are driven to move together, thereby driving the four telescopic rotating rods 35 to rotate and retract.

[0056] The four sleeve rods 31, the four limit sliding frames 32, the eight connecting blocks 34, the four telescopic rotating rods 35 and the disc 30 form the four rotating rods 23 and the four arc blocks 19 into a whole, which not only makes the arc blocks 19 move only along the contraction trajectory of the limit sliding frames 32 and the rotation trajectory of the telescopic rotating rods 35, thereby preventing the four arc blocks 19 from being offset when moving closer to each other, but also because the four arc blocks 19 form a whole, the situation in which the arc blocks 19 move downward due to their own weight is avoided, so that the cable reel can be supported and placed more stably.

[0057] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
