Description

Technical Field

[0001] The present invention relates to the field of cable production, and particularly to an insulated cable and a processing device. Background Art

[0002] In the field of insulated cable production, there are multiple key links. Firstly, the selection of raw materials, including conductor materials such as copper and aluminum, and various insulating materials. Then, through specific production processes, the conductor and insulating materials are combined to form a cable with good insulation performance and electrical conductivity. During the production process, strict quality inspections are also required to ensure that the cable performance meets the standard requirements. In the production process of insulated cables, a pay-off stand is an indispensable device. The pay-off stand for insulated cable production is mainly used to support and pay out the cable reels. In the production process of insulated cables, a pay-off stand is an indispensable device. The pay-off stand for insulated cable production is mainly used to support and pay out the cable reels.

[0003] The Chinese patent with the publication number CN206532646U discloses "a simple pay-off stand for cable production, including a bracket. The lower end of the bracket is fixedly installed with a mounting plate, and the upper end of the bracket is also fixedly installed with a workbench". Although it has a low cost, the operator only needs to step on the foot pedal to control the pay-off stand to work, and it is small in size and low in cost, which is convenient for small and micro enterprises to promote and use. However, different inner diameters of cable reels mean that the support structure of the pay-off stand needs to be able to be adjusted flexibly to adapt to various sizes, and this patent cannot support cable reels with different inner diameters and widths, increasing the limitations of the pay-off stand. Summary of the Invention

[0004] The main purpose of the present invention is to provide an insulated cable and a processing device. By moving two fixing frames away from or towards each other, the tensioning and placing structure can be driven, and thus cable reels with different inner diameters can be supported and placed.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A processing device for an insulating cable, comprising two first fixing frames. Between the two first fixing frames, two second fixing frames are arranged. At the front and rear parts of the tops of the two second fixing frames, fixing blocks are fixedly connected. Between the two first fixing frames, double-threaded lead screws one are rotatably connected at the front and rear parts. One ends of the two double-threaded lead screws one respectively penetrate through the sides of the first fixing frames on one side and are fixedly connected with belt pulleys. A belt is sleeved between the two belt pulleys. At the front part of the side of the first fixing frame on one side, an installation frame is fixedly connected. On the side of the installation frame, a first motor is fixedly connected. Sliding grooves are opened on both sides of the two second fixing frames. The second fixing frames are slidably connected with sliding frames through the sliding grooves on both sides. The double-threaded lead screws one are in threaded connection with the fixing blocks. At the top of the sliding frame, a vertical rod is fixedly connected. A tensioning and placing structure is arranged between the two front vertical rods and between the two rear vertical rods.

[0007] As a further scheme of the present invention, the tensioning and placing structure includes four rotating rods. Between the two vertical rods, four arc-shaped blocks are arranged. On the outer surface of the arc-shaped blocks, connecting blocks one are fixedly connected. At the top and bottom of the side of the vertical rod, connecting blocks two are fixedly connected. Between the connecting blocks one and the connecting blocks two, connecting rods are rotatably connected. The rotating rods are rotatably connected to the front part of the arc-shaped blocks. One end of the rotating rod penetrates through the rear part of the arc-shaped block and is fixedly connected with a limiting block one. Between the two second fixing frames, placing blocks one are arranged at the front and rear parts. Between the two front sliding frames and the two rear sliding frames, a placing block two is arranged. On both sides of the placing block one, connecting telescopic plates one are fixedly connected with the two fixing frames. On both sides of the placing block two, connecting telescopic plates two are fixedly connected with the two sliding frames. Between the two placing blocks one, a double-threaded lead screw two is rotatably connected. The double-threaded lead screw two is in threaded connection with the placing block two. At the front part of the front placing block one, a second motor is fixedly connected.

[0008] As a further scheme of the present invention, the output shaft of the first motor penetrates through the side of the installation frame and is fixedly connected with the front belt pulley. The output shaft of the second motor penetrates through the front placing block one and is fixedly connected with one end of the double-threaded lead screw two.

[0009] As a further scheme of the present invention, at the bottom of the four fixing blocks, universal wheels are fixedly connected. At the front and rear parts of the bottoms of the two first fixing frames, legs are fixedly connected. The height of the bottom of the legs is the same as the height of the bottom of the universal wheels.

[0010] As a further scheme of the present invention, at the front and rear parts of the two second fixing frames, a support structure is arranged. The support structure includes four rotating support rods. At the front and rear parts of the tops of the second fixing frames, connecting blocks three are fixedly connected. One end of the rotating support rod is rotatably connected with the connecting block three. At the tops of the four vertical rods, rotating connecting rods are rotatably connected. A support sliding rod penetrates through between the four rotating connecting rods. The two ends of the support sliding rod respectively penetrate through the front and rear parts of the four rotating support rods and are fixedly connected with limiting blocks two.

[0011] As a further solution of the present invention, a limiting structure is provided at one end of the four front rotating rods and one end of the four rear rotating rods. The limiting structure includes a disc, the disc is arranged at a position near one end between the four rotating rods, a sleeve rod is rotatably connected inside each rotating rod, four limiting sliding frames are symmetrically and slidably connected through the outer surface inside the disc, one end of the sleeve rod penetrates through the front part of the limiting sliding frame and is fixedly connected with a third limiting block, four connecting blocks four are symmetrically and fixedly connected at a position near the center of the rear part of the disc, and four connecting blocks four are also fixedly connected at positions near the center of the front part of the four arc-shaped blocks. A telescopic rotating rod is rotatably connected between the connecting block four located in the front of the arc-shaped block and the connecting block four located in the rear of the disc.

[0012] As a further solution of the present invention, the diameter of the arc-shaped block is larger than the diameter of the disc, and the diameter of the third limiting block is the same as the diameter of the rotating rod.

[0013] As a further solution of the present invention, the inclination angle of the limiting sliding frame is the same as the inclination angle of the telescopic rotating rod, and the maximum sliding distance of the limiting sliding frame is the same as the distance between two arc-shaped blocks located on the same diagonal line.

[0014] As a further solution of the present invention, the rotating direction of the telescopic rotating rod is the same as the sliding direction of the limiting sliding frame.

[0015] An insulated cable includes a conductor, an insulating layer, and a shielding layer. The conductor is the main current-carrying part in the cable, responsible for transmitting electric energy and signals. The conductor is made of either 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 anti-interference ability of the cable.

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

[0017] By setting the relaxation placement structure, when the two fixing frames two on both sides move towards each other and drive the four vertical rods to move, the four connecting rods drive the four arc-shaped blocks to approach each other, reducing the distance between the four rotating rods, and enabling the support and placement operation of cable reels with smaller inner diameters. Therefore, when the two fixing frames two on both sides move towards each other, the four rotating rods automatically contract to adapt to cable reels with smaller inner diameters, 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 II can be effectively supported. During the operation of the equipment, the fixing frame II and the components connected to the fixing frame II no longer rely solely on the two double-threaded lead screws I for support. This greatly reduces the working burden of the double-threaded lead screws I. By sharing the support pressure, the working life of the double-threaded lead screws I is increased, and the maintenance cost and downtime of the equipment are reduced. At the same time, when the two fixing frames II move towards each other, the universal wheels can make the movement of the fixing frame II more stable. The flexibility of the universal wheels enables the fixing frame II to smoothly adjust its position during movement, avoiding shaking and bumping, and ensuring the reliability and safety of the equipment operation;

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

[0020] By setting the limiting structure, the four sleeve rods, the four limiting sliding frames, the eight connecting blocks IV, the four telescopic rotating rods and the disc form a whole for the four rotating rods and the four arc-shaped blocks respectively. The arc-shaped blocks can only move along the contraction track of the limiting sliding frame and the rotation track of the telescopic rotating rod, effectively preventing the situation of position deviation when the four arc-shaped blocks move closer to each other, ensuring that the support points of the four rotating rods on the cable reel are always in the correct positions, improving the stability and reliability of the support. Since the four arc-shaped blocks form a whole, the stability of the structure is greatly enhanced, avoiding the situation of the arc-shaped blocks moving downward due to their own weight, ensuring that during the process of supporting and placing the cable reel, the arc-shaped blocks always remain in the correct positions and will not generate displacement changes due to their own gravity, thus providing continuous and stable support for the cable reel.

Detailed implementation manners

[0029] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0030] Such as Figure 1 - Figure 7As shown in the figure, a processing device for an insulating cable includes two first fixing frames 1. Between the two first fixing frames 1, two second fixing frames 2 are arranged. At the front and rear parts of the tops of the two second fixing frames 2, fixing blocks 6 are fixedly connected. Between the two first fixing frames 1, at the front and rear parts, a double-threaded lead screw 7 is rotatably connected. One ends of the two double-threaded lead screws 7 respectively penetrate through the sides of the first fixing frame 1 on one side and are fixedly connected with belt pulleys 8. A belt is sleeved between the two belt pulleys 8. At the front part of the side of the first fixing frame 1 on one side, an installation frame is fixedly connected. On the side of the installation frame, a first motor 9 is fixedly connected. Sliding grooves 14 are opened on both sides of the two second fixing frames 2. The second fixing frames 2 are slidably connected with sliding frames 13 through the sliding grooves 14 on both sides. The double-threaded lead screw 7 is threadedly connected with the fixing block 6. At the top of the sliding frame 13, a vertical rod 12 is fixedly connected. A relaxation placement structure 4 is arranged between the two front vertical rods 12 and between the two rear vertical rods 12;

[0031] The relaxation placement structure 4 includes four rotating rods 23. Between the two vertical rods 12, four arc-shaped blocks 19 are arranged. On the outer surface of the arc-shaped block 19, a first connecting block 20 is fixedly connected. At the top and bottom of the side of the vertical rod 12, a second connecting block 21 is fixedly connected. Between the first connecting block 20 and the second connecting block 21, a connecting rod 22 is rotatably connected. The rotating rod 23 is rotatably connected to the front part of the arc-shaped block 19. One end of the rotating rod 23 penetrates through the rear part of the arc-shaped block 19 and is fixedly connected with a first limiting block 24;

[0032] Start the first motor 9 to drive the front belt pulley 8 to rotate, and then drive the rear belt pulley 8 to rotate through the belt, thereby driving the two double-threaded lead screws 7 to rotate synchronously. Then, the two second fixing frames 2 move towards each other, and then drive the four vertical rods 12 on both sides to move towards each other as well, thereby changing the distance between the two second fixing frames 2, so that cable reels with any outer diameter can be placed between the two second fixing frames 2;

[0033] When the two second fixing frames 2 move towards each other and drive the four vertical rods 12 on both sides to move together, the four front connecting rods 22 all move, thereby driving the four front arc-shaped blocks 19 to approach each other, and then making the distance between the four rotating rods 23 decrease. Then, the four rotating rods 23 can be used to support and place a cable reel with a smaller inner diameter. The movement trajectories of the four rear connecting rods 22 are the same as the above.

[0034] In this embodiment, placing blocks one 11 are arranged at the front and rear parts between the two fixing frames two 2. A placing block two is arranged between the two sliding frames 13 at the front part and the two sliding frames 13 at the rear part. Connecting telescopic plates one 10 are fixedly connected between both sides of the placing block one 11 and the two fixing frames two 2. Connecting telescopic plates two are fixedly connected between both sides of the placing block two and the two sliding frames 13. A double-threaded lead screw two 15 is rotatably connected between the two placing blocks one 11. The double-threaded lead screw two 15 is in threaded connection with the placing block two. A motor two 16 is fixedly connected to the front part of the placing block one 11 at the front part;

[0035] Start the motor two 16 to drive the double-threaded lead screw two 15 to rotate. Then, through the two placing blocks two and the four connecting telescopic plates two, drive the two sliding frames 13 at the front part and the two sliding frames 13 at the rear part to slide towards each other along the four chutes 14. Then, drive the two vertical rods 12 at the front part and the two vertical rods 12 at the rear part to slide towards each other, thereby reducing the distance between the two pairs of front and rear vertical rods 12. Therefore, not only can it adapt to cable reels of different lengths, but also multiple rotating rods 23 can be automatically inserted into the inner ring of the cable reel to perform the support placement operation.

[0036] In this embodiment, the output shaft of the motor one 9 penetrates through the side surface of the mounting frame and is fixedly connected to the front pulley 8. The output shaft of the motor two 16 penetrates through the placing block one 11 at the front part and is fixedly connected to one end of the double-threaded lead screw two 15.

[0037] In this embodiment, universal wheels 17 are fixedly connected to the bottoms of the four fixing blocks 6. Legs 18 are fixedly connected to the front and rear parts of the bottoms of the two fixing frames one 1. The height of the bottom of the leg 18 is the same as the height of the bottom of the universal wheel 17;

[0038] The four universal wheels 17 can support the two fixing frames two 2, so that the fixing frames two 2 and the components connected to the fixing frames two 2 do not need to rely only on the two double-threaded lead screws one 7 for support. Thus, the working burden of the two double-threaded lead screws one 7 is reduced, the working life of the double-threaded lead screws one 7 is increased, and when the two fixing frames two 2 move towards each other, the four universal wheels 17 can also make the movement of the fixing frames two 2 more stable.

[0039] In this embodiment, a support structure 3 is arranged at the front and rear parts of the two fixing frames two 2. The support structure 3 includes four rotating support rods 26. Connecting blocks three 25 are fixedly connected to the front and rear parts of the tops of the fixing frames two 2. One end of the rotating support rod 26 is rotatably connected to the connecting block three 25. Rotating connecting rods 29 are rotatably connected to the tops of the four vertical rods 12. A support sliding rod 27 penetrates through between the four rotating connecting rods 29. Limiting blocks two 28 are fixedly connected to both ends of the support sliding rod 27 after passing through the front and rear parts of the four rotating support rods 26 respectively;

[0040] While the two vertical rods 12 at the front part and the two vertical rods 12 at the rear part move towards each other, the two rotating connecting rods 29 at the front part and the two rotating connecting rods 29 at the rear part move towards each other along the supporting sliding rod 27. Therefore, when the vertical rod 12 slides, it can slide not only through a supporting point of the sliding frame 13 and the sliding groove 14, but also through the rotating connecting rod 29 and the supporting sliding rod 27, so that the vertical rod 12 is more stable during the moving process;

[0041] While the two fixing frames II 2 move towards each other to drive the four vertical rods 12 on both sides to move towards each other, the two rotating supporting rods 26 at the front part rotate synchronously, and the distance between one ends of the two rotating supporting rods 26 at the front part is shortened. Therefore, its supporting sliding rod 27 will be lifted. The movement tracks of the two rotating supporting rods 26 at the rear part are the same as those above. While the supporting sliding rod 27 rises, it will drive the four rotating connecting rods 29 to rotate together. Although the rotating connecting rod 29 rotates, it will not separate from the supporting sliding rod 27. Therefore, even after the vertical rods 12 on both sides move towards each other, the supporting sliding rod 27 can still support the tops of the vertical rods 12.

[0042] In this embodiment, a limiting structure 5 is arranged at one ends of the four rotating rods 23 at the front part and one ends of the four rotating rods 23 at the rear part. The limiting structure 5 includes a disc 30. The disc 30 is arranged at a position near one end among the four rotating rods 23. A sleeve rod 31 is rotatably connected inside each rotating rod 23. Four limiting sliding frames 32 are symmetrically and slidably connected through the outer surface of the disc 30. One end of the sleeve rod 31 penetrates through the front part of the limiting sliding frame 32 and is fixedly connected with a third limiting block 33. Four connecting blocks IV 34 are symmetrically and fixedly connected at a position near the center of the rear part of the disc 30. Moreover, four connecting blocks IV 34 are also fixedly connected at positions near the center of the front parts of the four arc-shaped blocks 19. A telescopic rotating rod 35 is rotatably connected between the connecting block IV 34 at the front part of the arc-shaped block 19 and the connecting block IV 34 at the rear part of the disc 30;

[0043] While the four rotating rods 23 move and contract, the four sleeve rods 31 drive the four limiting sliding frames 32 to contract and slide. While the four arc-shaped blocks 19 contract and move, they drive the connecting blocks IV 34 connected with the arc-shaped blocks 19 to move together, thereby driving the four telescopic rotating rods 35 to rotate and contract;

[0044] Four sleeve rods 31, four limit sliding frames 32, eight connecting blocks four 34, four telescopic rotating rods 35 and a disc 30 form an integral body with the four rotating rods 23 and the four arc-shaped blocks 19 respectively. This not only enables the arc-shaped blocks 19 to 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-shaped blocks 19 from shifting in position when moving closer to each other, but also since the four arc-shaped blocks 19 form an integral body, it avoids the situation where the arc-shaped blocks 19 move downward due to their own weight. Thus, the cable reel can be supported and placed more stably.

[0045] In this embodiment, the diameter of the arc-shaped block 19 is greater than the diameter of the disc 30, and the diameter of the limit block three 33 is the same as the diameter of the rotating rod 23.

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

[0047] An insulated cable includes a conductor, an insulating layer, and a shielding layer. The conductor is the main current-carrying part in the cable, responsible for transmitting electrical energy and signals. The conductor is made of either copper or aluminum. The function of the insulating layer is to isolate the conductor, preventing current leakage or accidental contact that may cause electric shock and short circuits. The shielding layer can reduce the interference of the electromagnetic field around the cable and enhance the anti-interference ability of the cable.

[0048] It should be noted that for an insulated cable and a processing device of the present invention, when in use, start the first motor 9 to drive the front pulley 8 to rotate, and then drive the rear pulley 8 to rotate through the belt, thereby driving the two double-threaded lead screws one 7 to rotate synchronously. Then, the two fixing frames two 2 move towards each other, thereby driving the four vertical rods 12 on both sides to also move towards each other, thereby changing the distance between the two fixing frames two 2, enabling cable reels of any outer diameter to be placed between the two fixing frames two 2;

[0049] While the two fixing frames two 2 move towards each other and drive the four vertical rods 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 move closer to each other, thereby reducing the distance between the four rotating rods 23. Thus, cable reels with a smaller inner diameter can be supported and placed by the four rotating rods 23. The movement trajectory of the four connecting rods 22 at the rear part is the same as the above;

[0050] When the four rotating rods 23 at the front part and the four rotating rods 23 at the rear part are both inserted into the inner ring of the cable reel, 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 tape armoring device, and the steel tape is wound around the outer surface of the cable, providing a strong external protective layer for the cable, which can effectively resist external mechanical pressures, impacts, squeezes and other external forces.

[0051] Start the second motor 16 to drive the double-threaded lead screw 15 to rotate. Then, through the two placing blocks 15 and the four connecting telescopic plates 15, drive the two sliding frames 13 at the front part and the two sliding frames 13 at the rear part to slide towards each other along the four sliding grooves 14. Then, drive the two vertical rods 12 at the front part and the two vertical rods 12 at the rear part to slide towards each other, thereby reducing the distance between the two pairs of front and rear vertical rods 12. Therefore, not only can it adapt to cable reels of different lengths, but also multiple rotating rods 23 can be automatically inserted into the inner ring of the cable reel to perform the support placement operation.

[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 only on the two double-threaded lead screws 7 for support. Thus, the working burden of the two double-threaded lead screws 7 is reduced, the working life of the double-threaded lead screws 7 is increased, and when the two fixing frames 2 move towards each other, the four universal wheels 17 can also make the movement of the fixing frames 2 more stable.

[0053] When the two front vertical rods 12 and the two rear vertical rods 12 move towards each other, the two front rotating connecting rods 29 and the two rear rotating connecting rods 29 move towards each other along the support sliding rod 27. Therefore, when the vertical rod 12 slides, it can slide not only through a support point of the sliding frame 13 and the sliding groove 14, but also through the rotating connecting rod 29 and the support sliding rod 27. Therefore, the vertical rod 12 is more stable during the movement process.

[0054] When the two fixing frames 2 move towards each other and drive the four vertical rods 12 on both sides to move towards each other, the two front rotating support rods 26 rotate synchronously, and the distance between one ends of the two front rotating support rods 26 is shortened. Therefore, its support sliding rod 27 will be lifted. The movement trajectories of the two rear rotating support rods 26 are the same as the above. When the support sliding rod 27 rises, it will drive the four rotating connecting rods 29 to rotate together. Although the rotating connecting rod 29 rotates, it will not separate from the support sliding rod 27. Therefore, even after the vertical rods 12 on both sides move towards each other, the support sliding rod 27 can still support the tops of the vertical rods 12.

[0055] While the four rotating rods 23 move and contract, they drive the four sleeve rods 31 to drive the four limit sliding frames 32 to contract and slide. While the four arc-shaped blocks 19 contract and move, they drive the connecting blocks four 34 connected to the arc-shaped blocks 19 to move together, thereby driving the four telescopic rotating rods 35 to rotate and contract;

[0056] The four sleeve rods 31, the four limit sliding frames 32, the eight connecting blocks four 34, the four telescopic rotating rods 35 and the disc 30 form a whole for the four rotating rods 23 and the four arc-shaped blocks 19 respectively. This not only makes the arc-shaped blocks 19 can only move 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-shaped blocks 19 from shifting in position when moving closer to each other, but also because the four arc-shaped blocks 19 form a whole, the situation that the arc-shaped blocks 19 move downward due to their own weight is avoided. Furthermore, the cable reel can be supported and placed more stably.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
