Technical Field
[0001] This invention relates to the field of cable production, specifically to an insulated cable braiding device based on cable production. Background Technology
[0002] Cross-linked polyethylene (XLPE) insulated power cables have become a core material for smart grid construction due to their excellent electrical properties, heat resistance, long lifespan, lightweight structure, large transmission capacity, and convenient installation and maintenance. With the increasing demand for smart grid construction and new energy access, the market share of XLPE insulated power cables continues to expand, and they are widely used in key areas such as high-voltage power transmission, submarine cables, rail transit, and urban underground power grids.
[0003] In the manufacturing process of cross-linked polyethylene insulated power cables, the cabling process is one of the key steps determining product performance. When multiple insulated cores are stranded together, numerous irregular gaps are formed between them. To ensure the roundness of the cable structure, improve mechanical impact resistance, and prevent relative slippage of the cores, filler ropes (such as PP rope, hemp rope, cotton rope, or fiberglass rope) must be filled into these gaps. The uniformity of the filler rope winding and the stability of its tension directly affect the stability and reliability of the cable in critical areas such as high-voltage power transmission, submarine cables, rail transit, and urban underground power grids.
[0004] Currently, cable braiding equipment mainly consists of three parts: the pay-off system, the braiding machine, and the take-up system. The pay-off system supplies filler rope material to the braiding machine, and its core components include a drum, a mounting frame, and a take-up reel. The initial filler rope material is wound onto the drum, which is mounted on the take-up reel via the mounting frame. A drive unit rotates the drum to achieve continuous unwinding.
[0005] However, in actual production, when the filler rope material on the drum is exhausted and needs to be replaced, the drum replacement operation is cumbersome and time-consuming. The drums of existing equipment are usually fixed to the frame by bolts, clamps or complex mechanical locking devices. When replacing the drum, the operator needs to use tools to disassemble the locking parts one by one, remove the empty drum, and then align the new drum with the installation position and re-lock it. This process often requires two or more operators to work together. Each replacement takes a long time, which seriously restricts the continuity and efficiency of cable production. At the same time, there are also situations where work is done at height. The high intensity of labor will inevitably increase the danger.
[0006] Therefore, an insulated cable braiding device based on cable production is proposed to address the above problems. Summary of the Invention
[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0008] The technical solution adopted by the present invention to solve its technical problem is: the present invention provides an insulated cable braiding device based on cable production, including a unwinding reel, the unwinding reel including two reels arranged on the same axis, and a plurality of support frames for holding material rolls are arranged between the reels; Each of the support frames includes a rectangular frame, in which a material roll is rotatably connected. Each rectangular frame has slide rails on both sides of its outer side. The two slide rails of the same rectangular frame are slidably connected in a groove opened on the inner side wall of the disc in a horizontal direction, and the groove opening extends to the outer edge of the disc. Multiple mounting ports are provided on the outer edge of each disc body. Each mounting port is arranged to coincide with the groove opening of the slide. Each mounting port is equipped with a top block, and the outer edge of the top block and the outer edge of the disc body form a complete circle. Each of the top blocks has a fixing plate symmetrically arranged on both sides of its side wall, and a fixing pin is provided on the inner side wall of the end of each fixing plate. Fixing holes adapted to the fixing pins are opened on the disc body.
[0009] Preferably, each of the rectangular frames includes two U-shaped movable frames, each movable frame extending vertically outward at one end and fixed to a slide rail; Two slide rails on the same side of two adjacent movable frames are connected together by a traction assembly. The traction assembly includes a plug rod set on the end face of one of the slide rails, with a tension spring fixed to the end of the plug rod. An insertion hole is opened on the end face of the other slide rail, with the end of the tension spring fixed in the insertion hole. The plug rod is slidably connected in the insertion hole.
[0010] Preferably, each of the top blocks is threaded with a set screw, which extends through the top block into the slide groove and abuts against another slide rail.
[0011] Preferably, each of the movable frames is provided with a thrust bearing on its inner sidewall, and the end face of the thrust bearing is pressed against the end face of the material roll by the traction force of the tension spring.
[0012] Preferably, the front end of the unwinding reel is further provided with a material filling structure, which is used to fill the inside of the cable with powdered material. The material filling structure includes a horizontally placed material cylinder, which is frustum-shaped. The diameter of the end face of the material cylinder near the unwinding reel is larger than the diameter of the end face away from the unwinding reel. Rotary bodies are rotatably connected to both end faces of the material cylinder. Through holes are opened at the eccentric position and the center position of each rotating body. A feeding port is provided on the upper edge of the material cylinder.
[0013] Preferably, a stirring rod is provided between the two rotating bodies, and the ends of the stirring rod are respectively fixed to the edges of the two rotating bodies.
[0014] Preferably, the rotating body and the disk are connected together by a connecting plate, and the disk drives the rotating body to rotate through the connecting plate.
[0015] Preferably, multiple horizontal strip-shaped holes are opened on the disc body near the material cylinder, each strip-shaped hole is correspondingly set with a support frame, and a guide block is slidably connected in the strip-shaped hole, with a through hole for material to pass through at the center of the guide block.
[0016] Preferably, one of the two adjacent movable frames has a positioning pin on its end face, and the other movable frame has a positioning hole adapted to the positioning pin on its end face. When the two adjacent movable frames are merged, the positioning pin is embedded in the positioning hole.
[0017] Preferably, each of the fixing plates is made of spring steel sheet material.
[0018] The advantages of this invention are: 1. In this invention, a sliding rail and sliding groove sliding fit structure is adopted to realize the quick assembly and disassembly of the support frame and the reel. When changing the material roll, there is no need to disassemble the bolts, clamps and other locking parts. Disassembly can be completed in just three steps: pulling out the fixing pin, removing the top block and sliding out the support frame. The operation is simple, which helps to improve the replacement efficiency and significantly improves the overall cable processing efficiency.
[0019] 2. In this invention, the material roll is pre-fixed on the support frame to avoid direct handling of the material roll. The material roll is cylindrical and difficult to fix, which can cause the material to be loose. However, the material roll is assembled on the support frame and then assembled on the unwinding reel through the support frame. During this process, there will be no interference with the material roll, and the material will not be loose or messy.
[0020] 3. In this invention, the material roll and support frame are integrated for handling. Operators no longer need to carry and disassemble rolls weighing tens of kilograms in confined spaces. They can simply push and pull the support frame to pick up and put down the rolls, which greatly reduces labor intensity. The slide rail and groove structure provides effective support for the support frame, avoiding the risk of slippage and injury that may occur when manually lifting the material rolls, and significantly improving operational safety. Furthermore, the plug-in locking structure of the fixing pin and fixing hole is simple and reliable, eliminating the need to repeatedly tighten the bolts and removing the problems of thread wear and limited tool operating space.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0024] Reference Figure 1 - Figure 4 ,as well as Figure 6 - Figure 11 An insulated cable braiding device based on cable production includes an unwinding reel 1 and a drive assembly that supports and drives the unwinding reel 1 to rotate. The drive assembly includes a base plate 2, on which a drive wheel 3 is provided. The outer ring of the drive wheel 3 has a radial groove, and the outer ring of the unwinding reel 1 is embedded in the groove. The drive wheel 3 is driven to rotate by a reduction motor, thereby driving the unwinding reel 1 to rotate. A wire threading hole is provided at the center of the unwinding reel 1, and the cable core 101 moves along the wire threading hole. The unwinding reel 1 includes two reels 4 arranged coaxially, and multiple support frames 6 for mounting material rolls 5 are arranged between the reels 4; each support frame 6 includes a rectangular frame 7, and the material roll 5 is rotatably connected in each rectangular frame 7. The cable core 101 is wound up by a winding wheel. The cable core 101 moves and can pull the material on the material roll 5 to release it, and the material is the filler rope 102. Each rectangular frame 7 has slide rails 8 on both sides. The two slide rails 8 of the same rectangular frame 7 are slidably connected in the horizontal direction in the slide grooves 9 opened on the inner side wall of the disc body 4, and the groove opening of the slide groove 9 extends to the outer edge of the disc body 4. Each outer edge of the disc body 4 has multiple mounting holes 10, which are arranged to coincide with the groove opening of the slide groove 9. Each mounting hole 10 is equipped with a top block 11, and the outer edge of the top block 11 and the outer edge of the disc body 4 form a complete circle. Each top block 11 has a fixing plate 12 symmetrically arranged on both side walls. Each fixing plate 12 has a fixing pin 13 on the inner side wall of its end. The disc body 4 has fixing holes 14 adapted to the fixing pins 13. The front end of the unwinding reel 1 is also provided with a cylinder 15, the center of the cylinder 15 is aligned with the wire hole, a constraint ring 16 is provided on the outer ring of the cylinder 15 to constrain the movement of the filling rope 102, and a disc-shaped support 17 is provided at the end of the cylinder 15. The support 17 has a hole for the filling rope 102 to pass through at an eccentric position, and the center of the support 17 passes through and is connected to the center of the cylinder 15. The support 17 is supported on the ground by a support plate 35. A winding cylinder 18 is provided at the front end of the support 17, and the filling rope 102 is wound and braided on the cable core 101 inside the winding cylinder 18. In this embodiment of the invention, the main focus is on optimizing the replacement of material roll 5 in the cable braiding equipment. The existing material roll 5 replacement process is cumbersome, time-consuming, and labor-intensive, affecting the overall cable production efficiency and posing a certain degree of danger. Therefore, a structure is designed to facilitate the replacement of material roll 5. The material roll 5 replacement operation procedure is as follows: When replacing material roll 5, the operator can directly remove the support frame 6 as a whole, without disassembling material rolls 5 one by one. The specific operation steps are: First, remove the fixing pin 13 from the fixing hole 14 to release the locking state of the top block 11; then pull the top block 11 backward to disengage it from the installation. At this point, the top block 11 no longer blocks the opening of the slide groove 9, and the slide groove 9 is connected to the outside. Then push the support frame 6 so that the slide rail 8 slides outward along the slide groove 9 until the support frame 6 is completely removed. During this process, the material roll 5 is removed together with the support frame 6, realizing the overall replacement of the material roll 5 and the support frame 6. The new material roll 5 can be pre-assembled on the support frame 6 outside the equipment, and then the reverse operation can be used to quickly install it in place. Align the slide rail 8 of the support frame 6 with the new material roll 5 and push it into the slide groove 9. Install the top block 11 so that the fixing pin 13 is inserted into the fixing hole 14 to lock it, and the replacement can be completed. In this invention, a sliding fit structure of slide rail 8 and slide groove 9 is adopted to realize the quick assembly and disassembly of support frame 6 and disc body 4. When changing material roll 5, there is no need to disassemble bolts, clamps and other locking parts. Disassembly can be completed in three steps: pulling out fixing pin 13, removing top block 11 and sliding out support frame 6. The operation is simple, which helps to improve replacement efficiency and significantly improve the overall cable processing efficiency. Meanwhile, the material roll 5 is pre-fixed on the support frame 6 to avoid directly handling the material roll 5. The material roll 5 is cylindrical and not easy to fix, which will cause the material to be loose. However, the material roll 5 is assembled on the support frame 6 and then assembled on the unwinding reel 1 through the support frame 6. During this process, there will be no interference with the material roll 5, so the material will not be loose and messy. Furthermore, this invention enables the integrated handling of the material roll 5 and the support frame 6. Operators no longer need to carry and disassemble rolls weighing tens of kilograms in confined spaces; they can simply push and pull the support frame 6 to pick up and put down the rolls, significantly reducing labor intensity. The slide rail 8 and slide groove 9 structure effectively support the support frame 6, avoiding the risk of slippage and injury that may occur when manually lifting the material roll 5, thus significantly improving operational safety. Moreover, the plug-in locking structure of the fixing pin 13 and the fixing hole 14 is simple and reliable, eliminating the need to repeatedly tighten bolts and removing the problems of thread wear and limited tool operating space.
[0025] Reference Figure 6 - Figure 11 Each of the rectangular frames 7 includes two U-shaped movable frames 19, each movable frame 19 extending vertically outward at its end and fixedly connected to a slide rail 8; the two slide rails 8 on the same side of two adjacent movable frames 19 are connected together by a traction assembly, and the traction assembly includes a plug rod 20 disposed on the end face of one of the slide rails 8, the end of the plug rod 20 being fixedly connected to a tension spring 21, and the end face of the other slide rail 8 having a socket 22, the end of the tension spring 21 being fixedly connected in the socket 22, and the plug rod 20 being slidably connected in the socket 22; Material roll 5 is pre-assembled on support frame 6 outside the equipment. The specific operation is as follows: pull apart the two adjacent movable frames 19, the insertion rod 20 slides along the insertion hole 22, and the tension spring 21 is stretched and stored. At this time, space is made to replace material roll 5. Remove the material roll 5 that has been used up and install the new material roll 5. Then release the movable frame 19. The movable frame 19 returns to its original position by the pulling force of the tension spring 21. At this time, the pulling force of the tension spring 21 causes the two movable frames 19 to press against the material roll 5 inside them, fixing the material roll 5. This operation prepares the material roll 5 in advance for subsequent material loading.
[0026] Reference Figure 6 - Figure 11 Each of the top blocks 11 is threaded with a top screw 23, which extends through the top block 11 into the slide groove 9 and abuts against another slide rail 8; When the support frame 6 is initially fixed, the top block 11 is assembled into the mounting port 10. The top block 11 and the unwinding reel 1 are quickly positioned and locked by the insertion and engagement of the fixing pin 13 and the fixing hole 14. At the same time, the top block 11 seals the groove 9 to prevent the slide rail 8 from slipping out of the groove 9. During the second tightening, the end of the top screw 23 is pressed against the end face of the slide rail 8 by rotating it. The self-locking characteristic of the thread drive generates a continuous and stable tightening force, which further eliminates the fit gap between the slide rail 8 and the groove 9. This effectively prevents the support frame 6 from radially running or axially moving during the rotation of the reel 4. This double locking structure makes the support frame 6 and the reel 4 form a rigid integrated connection, which significantly improves the overall structural strength and operational stability of the unwinding reel 1.
[0027] Reference Figure 6 - Figure 8 Each of the movable frames 19 has a thrust bearing 24 on its inner sidewall. The end face of the thrust bearing 24 is pressed against the end face of the material roll 5 by the traction force of the tension spring 21. The end of the filler rope 102 is wrapped around the cable core 101. The material roll 5 releases the filler rope 102 by relying on the pulling force of the cable core 101. At this time, the smoothness of the material roll 5 releasing the filler rope 102 needs to be considered. The two adjacent movable frames 19 are pulled and clamped at the end of the material roll 5 by the tension spring 21. For this purpose, a thrust bearing 24 is set to improve the smoothness of the rotation of the material roll 5. The end face of the material roll 5 presses against the thrust bearing 24, converting the sliding friction between the material roll 5 and the movable frame 19 into rolling friction between the material roll 5 and the thrust bearing 24, thereby improving the smoothness of the rotation of the material roll 5. As a result, the cable core 101 can smoothly pull the filler rope 102, which also reduces the possibility of internal damage to the cable core 101 due to resisting high-intensity reverse pulling force.
[0028] Reference Figure 1 - Figure 5 ,as well as Figure 9 The front end of the unwinding reel 1 is also provided with a material filling structure. The material filling structure is used to fill the inside of the cable with powdered material. The material filling structure includes a horizontally placed material cylinder 25. The material cylinder 25 is frustum shaped. The diameter of the end face of the material cylinder 25 near the unwinding reel 1 is larger than the diameter of the end face away from the unwinding reel 1. Rotary bodies 26 are rotatably connected to both end faces of the material cylinder 25. Through holes 27 are opened at the eccentric position and the center position of each rotating body 26. A feeding port 28 is provided on the upper edge of the material cylinder 25. In this embodiment of the invention, the filler rope 102 is wound and braided around the cable core 101 to fill the gaps between the cores, making the cable cross-section round and improving the cable quality. It also enhances the compressive and tensile strength, meeting the cable production quality requirements. Furthermore, some cables, during production, may have materials added to improve certain characteristics based on production requirements or customized specifications. For example, adding calcined clay improves the cable's insulation and heat resistance; adding barium sulfate minerals improves the cable's flame retardancy and temperature resistance; adding aluminum hydroxide / magnesium hydroxide improves the cable's flame retardancy, smoke suppression, and high-temperature heat absorption. Therefore, this invention designs a material filling structure that improves the filling effect. Specifically, powdered material is fed into the feed inlet 28, falling into and filling the entire material cylinder 25. The cable core 101 moves along the through hole 27 at the center of the rotating body 26, while the remaining filler ropes 102 move along the through holes 27 at the eccentric position of the rotating body 26. During the process of the cable core 101 and filler ropes 102 moving into the material cylinder 25, the powdery material in the material cylinder 25 will soak the cable core 101 and filler ropes 102, and the surfaces of the cable core 101 and filler ropes 102 will be saturated with powdery material. After moving into the cylinder 15, the filler ropes 102 are wrapped around the surface of the cable core 101, and at the same time, the filler ropes 102 wrap the powdery material. In the subsequent movement, the filler ropes 102 can still firmly wrap most of the powdery material, and some of the powdery material will act as filler to further fill the gaps between the cable cores 101.
[0029] Reference Figure 5 and Figure 9 A stirring rod 29 is provided between the two rotating bodies 26, and the ends of the stirring rod 29 are respectively fixed to the edge positions of the two rotating bodies 26; The unwinding reel 1 drives multiple filler ropes 102 to rotate around its own axis. At the same time, the filler ropes 102 pass through the through holes 27 on the two rotating bodies 26 and apply a compressive force to the rotating bodies 26, driving the rotating bodies 26 to rotate around the axis of the material cylinder 25. Simultaneously, the two rotating bodies 26 drive the stirring rod 29 between them to rotate. The stirring rod 29 stirs the powdery material in the material cylinder 25. The powdery material is stirred and filled, and the powdery material can fully adhere to the surface of the cable core 101 and the filler ropes 102, so as to prevent the powdery material from failing to make effective contact with the filler ropes 102 and the cable core 101.
[0030] Reference Figure 5 and Figure 9 The rotating body 26 and the disk body 4 are connected together by a connecting plate 30, and the disk body 4 drives the rotating body 26 to rotate through the connecting plate 30; The cylinder 15 is fixed to the center of the end face of the disc 4. The end of the cylinder 15 is fixed to the support body 17. The outer ring of the support body 17 is supported on the ground by the support plate 35, and the support body 17 is rotatably connected to the support plate 35. The outer edge of the end face of the support body 17 is connected to the nearby rotating body 26 by the connecting plate 30, so that the rotating body 26, the support body 17, the cylinder 15 and the disc 4 become a whole. That is, the source of power for driving the rotating body 26 to rotate is the geared motor that drives the disc 4 to rotate, so that the rotating body 26 and the stirring rod 29 have greater rotational power, thereby easily promoting the peristalsis of the powdered material in the material cylinder 25. If the rotating body 26 is pushed by multiple filling ropes 102 to twist, the reverse torsional force may damage the filling ropes 102.
[0031] Reference Figure 1 , Figure 2 , Figure 10 and Figure 11 Multiple horizontal strip holes 31 are opened on the disc body 4 near the material cylinder 25. Each strip hole 31 is corresponding to the support frame 6, and a guide block 32 is slidably connected in the strip hole 31. A through hole for material to pass through is opened at the center of the guide block 32. When the filler rope 102 is released from the material roll 5, it swings freely and generates multiple uncertain friction points with the surrounding structure, such as the support frame 6 or the disc 4. The traditional structure for guiding the filler rope 102 usually has a strip hole 31 on the disc 4. The length of the strip hole 31 is close to the height of the material roll 5. However, there are many uncertain friction points on the inner surface of the strip hole 31, which causes the filler rope 102 to wear and fray, affecting the roundness of the cable, causing unstable tension, fluctuating cable quality, and easy breakage during high-speed production. Therefore, in this embodiment, a guide block 32 is set in the strip hole 31. The inner wall of the through hole on the guide block 32 becomes the only contact surface of the filler rope 102, replacing the multiple uncertain factors on the inner surface of the original strip hole 31. Moreover, the guide block 32 can be made of wear-resistant materials, such as nylon or polytetrafluoroethylene, and wear only occurs on the replaceable part of the guide block 32.
[0032] Reference Figure 6 - Figure 8 One of the two adjacent movable frames 19 has a positioning pin 33 on its end face, and the other movable frame 19 has a positioning hole 34 adapted to the positioning pin 33 on its end face. When the two adjacent movable frames 19 are merged, the positioning pin 33 is embedded in the positioning hole 34. The two adjacent movable frames 19 are joined together by the tension of the tension spring 21, and the positioning pin 33 is also inserted into the positioning hole 34, which can further improve the integrity and stability of the two adjacent movable frames 19, so that they can stably support the material roll 5.
[0033] Reference Figure 6 - Figure 8Each of the fixing plates 12 is made of spring steel sheet material; relying on the elasticity of the fixing plate 12 itself, the elastic force presses the fixing pin 13 on the fixing plate 12 into the fixing hole 14, thereby achieving the fixing between the fixing pin 13 and the fixing hole 14. The elastic performance of the fixing plate 12 also enables it to be used repeatedly.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
