Description

Technical Field

[0001] This invention relates to the field of cable production technology, specifically to a dehumidification device and its usage method in the cable wrapping production process. Background Technology

[0002] With the vigorous development and rapid rise of my country's economy, the power system, as a national infrastructure, has also ushered in unprecedented opportunities. High-voltage and ultra-high-voltage cross-linked polyethylene insulated power cables are being used more and more widely in the transformation and construction of urban and rural power grids. At present, the domestic cable production sector is also developing rapidly. Cross-linked polyethylene insulated cables account for more than 30% of the domestic power grid system. The performance requirements for cross-linked polyethylene insulated cables are becoming increasingly stringent, with key properties including water resistance, flame retardancy, and termite prevention.

[0003] Traditional cable wrapping production lines consist of a pay-off frame, a high-speed wrapping machine, a tracked traction machine, and a take-up frame. In high-humidity environments, this equipment can cause the semi-conductive buffer (water-blocking) layer to absorb moisture. When the ambient humidity exceeds 75%–85%, the finished cable may exhibit precipitation (a small amount of white powder (water-blocking powder or adhesive powder) precipitated from the wrapping layer). When the ambient humidity exceeds 85%, the finished cable is prone to precipitation (a large amount of white powder (water-blocking powder or adhesive powder) precipitated from the wrapping layer). The reason for this white powder precipitation is that the aluminum sheath comes into contact with the moisture-absorbing wrapping layer. The aluminum metal reacts with the water-blocking powder or adhesive after absorbing moisture, producing OH- ions that generate white Al2O3 powder, thus affecting the cable's safety. Summary of the Invention

[0004] The purpose of this invention is to provide a dehumidification device and its usage method in the cable wrapping production process, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dehumidification device for cable wrapping production process and its usage method, comprising a cable feeding frame, and further comprising: A winding roller rotates on the inner wall of the wire feeding frame. A working chamber is located on one side of the wire feeding frame. Inside the working chamber are two symmetrically designed traction mechanisms for pulling the cable. An adjustment mechanism for adjusting the position of the traction mechanisms is also located inside the working chamber. A take-up frame is installed inside the working chamber, and a take-up roller rotates on the inner wall of the take-up frame. The cable body wound on the inner wall of the unwinding roller includes a cable conductor, a conductor shield wrapped around the outside of the cable conductor, an insulation layer body wrapped around the outside of the conductor shield, an insulation shield layer wrapped around the outside of the insulation shield body, a buffer layer disposed outside the insulation shield layer, a metal sheath layer disposed outside the buffer layer, and a non-metallic sheath disposed outside the metal sheath layer.

[0006] Preferably, the traction mechanism includes two sets of housings symmetrically designed inside the work area. A motor is installed on one side of each housing. Two sets of transmission rollers are rotatably connected to the inner wall of each housing, and one side of each transmission roller is fixedly connected to the output end of the motor. A track is rotatably connected to the outer side of each transmission roller, and two sets of limiting rollers are rotatably connected to the inner wall of each housing.

[0007] Preferably, the adjustment mechanism includes a support frame fixed to the inner wall of the work area, the inner wall of the support frame is rotatably connected to a vertically arranged threaded rod, and a first movable block is installed on one side of the outer shell by screws, and the inner wall of the first movable block is threadedly connected to the outer side of the threaded rod.

[0008] Preferably, the inner walls of both the wire feeding frame and the wire take-up frame are fixed with support bases by screws, and the top of the support base is rotatably connected with a transmission rod, and one end of each of the two sets of transmission rods is fixedly connected to the axis of the take-up roller via a flange and the unwinding roller, respectively.

[0009] Preferably, a fixing frame is fixed on one side of both the cable feeding frame and the cable take-up frame, and a limiting frame for limiting the cable body is fixed at the bottom of the fixing frame, with rollers rotatably connected to the inner wall of the limiting frame.

[0010] Preferably, a fixing frame is fixed on one side of both the cable feeding frame and the cable take-up frame, and a limiting frame for limiting the cable body is fixed at the bottom of the fixing frame, with rollers rotatably connected to the inner wall of the limiting frame.

[0011] Preferably, a positioning block is fixed on the outer side of the outer shell, the inner wall of the positioning block is rotatably connected to the inner wall of the screw, and a snap-fit ​​block is threadedly connected to the outer side of the screw.

[0012] Preferably, two sets of second movable blocks are fixed to one side of the outer shell by screws, and two sets of vertically arranged limiting rods are fixed to the inner wall of the working chamber, with the outer side of the limiting rods slidably connected to the inner wall of the second movable blocks.

[0013] Preferably, the inner wall of the work area is equipped with a first winding head machine and a second winding head machine, and the first winding head machine and the second winding head machine are designed symmetrically. The interior of the work area is equipped with a first dehumidifying heater and a second dehumidifying heater, and the first dehumidifying heater is located on one side of the second winding head machine, and the second dehumidifying heater is located below the take-up frame.

[0014] This invention also provides a method for using a moisture-removing device in the cable wrapping production process and its application, comprising the following steps: S1. Preliminary Preparation and Equipment Installation: Place the pay-off frame and take-up frame securely in a suitable location in the production area. Using support bases and transmission rods, install the unwinding roller and take-up roller on the inner wall of the pay-off frame and take-up frame respectively via flanges, ensuring that the unwinding roller and take-up roller can rotate smoothly. Then, wind the cable body onto the unwinding roller. The cable body consists of the cable conductor, conductor shield, insulation layer, insulation shield layer, buffer layer, metal sheath layer, and non-metallic sheath layer from the inside out. Each layer is tightly wrapped to form the cable's protection system. Install a fixing frame on one side of the pay-off frame and take-up frame, and fix a limiting frame at the bottom of the fixing frame. The inner wall of the limiting frame is rotatably connected to rollers to limit the cable body and prevent it from deviating during transmission. S2. Cable Traction and Position Adjustment: Turn on the motor in the traction mechanism. The motor drives the transmission roller to rotate, and the track rotates accordingly to traction the cable. The limit roller can further limit the cable to ensure the stability of the traction process. If it is necessary to adjust the position of the traction mechanism, rotate the threaded rod in the adjustment mechanism. Since the first movable block is threadedly connected to the threaded rod and the first movable block is installed on one side of the outer shell, the outer shell will move up and down accordingly, thereby changing the position of the traction mechanism. The second movable block on one side of the outer shell slides on the limit rod to provide guidance for the movement of the outer shell and ensure smooth movement. S3. Wrapping and Dehumidification Operation: The cable enters the working chamber via the traction mechanism and first undergoes preliminary wrapping by the first wrapping head machine to add a layer of protection to the cable. Then, the cable reaches the second wrapping head machine for a second wrapping to further enhance the cable's protective performance. During the wrapping process, the first dehumidifying heater is located on one side of the second wrapping head machine to perform preliminary dehumidification on the cable after the initial wrapping, removing some moisture from the surface and inside of the cable. Afterward, the second dehumidifying heater is located below the take-up frame to perform deep dehumidification on the cable after the second wrapping, ensuring that the cable is completely dry. S4. Component maintenance and adjustment during production: If it is necessary to adjust the spacing of the drive rollers during production, the locking block on one side of the positioning block can be rotated. The locking block moves along the outside of the screw. Due to the obstruction of the positioning block, the locking block cannot be displaced. At this time, the screw will continue to be displaced along the inner wall of the locking block, which will drive the rotating rod and drive rollers to move.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention reduces the rework rate of re-wrapping. By modifying the production line and optimizing the production process, it reduces the moisture absorption of the wire core after wrapping, greatly improves the production efficiency of this process, reduces the scrap rate, saves costs, effectively improves the quality of the cable, enhances the safety and reliability of the cable in long-term operation, and thus extends the service life of the cable.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-8As shown, a dehumidification device and its usage method for a cable wrapping production process include a wire feeding frame 1. An unwinding roller 2 is rotatably connected to the inner wall of the wire feeding frame 1. The wire feeding frame 1 provides an installation position for the unwinding roller 2, allowing the cable body 3 wound on the unwinding roller 2 to be smoothly unwound into subsequent production processes. A working chamber 4 is provided on one side of the wire feeding frame 1. The working chamber 4 provides a relatively enclosed and stable working environment for the entire cable wrapping production process, facilitating the installation of various production equipment and production operations, while also aiding in environmental control. The working chamber 4 contains two sets of symmetrically designed traction mechanisms 5 for pulling the cable. The adjustment mechanism 6 adjusts the position of mechanism 5. The inside of the work area 4 is equipped with a take-up frame 7. The inner wall of the take-up frame 7 has a rotating take-up roller 8. The traction mechanism 5 can pull the cable through its internal structure, so that the cable can maintain a certain tension during the production process and pass through each production process smoothly, ensuring the continuity and stability of production. The adjustment mechanism 6 can adjust the position of the traction mechanism 5 through its internal structure to adapt to the production needs of cables of different specifications, ensuring that the traction mechanism 5 can accurately clamp and pull the cable. The take-up frame 7 and the take-up roller 8 are used to take up the cable body 3 after the production process, and neatly wind the cable on the take-up roller 8 for easy storage and transportation.

[0020] The cable body 3, wound around the inner wall of the unwinding roller 2, includes a cable conductor 9. The cable conductor 9 is wrapped with a conductor shield 10, which is then wrapped with an insulation layer body 11. An insulation shielding layer 12 is wrapped with the insulation layer body 11, and a buffer layer 13 is disposed outside the insulation shielding layer 12. A metal sheath layer 14 is disposed outside the buffer layer 13, and a non-metallic sheath 15 is disposed outside the metal sheath layer 14. The cable body 3 is the main product of the entire cable wrapping production process. After wrapping, dehumidification, and other processes, it forms the final product. The cable conductor 9, as the core conductive part of the cable, is responsible for transmitting electrical energy. The conductor shield 10 is used to improve the electric field distribution on the surface of the cable conductor 9, reduce partial discharge, and improve... Regarding the electrical performance of the cable, the insulation layer 11 provides electrical insulation, prevents current leakage, and ensures the safety and reliability of the cable during operation. The insulation shielding layer 12, similar to the conductor shielding layer 10, further optimizes the electric field distribution and provides a good interface for subsequent processes such as wrapping. The buffer layer 13 acts as a buffer when the cable is subjected to external forces, protecting the internal insulation layer 11 and conductor and reducing damage caused by external forces. The metal sheath layer 14 provides mechanical protection, preventing the cable from being damaged by external mechanical forces, and also has a certain shielding effect against electromagnetic interference. The non-metallic sheath 15 provides further protection for the cable, preventing moisture, chemicals, etc. from corroding the internal structure of the cable and extending the service life of the cable.

[0021] The specific process of cable processing: Wire drawing process; Wire drawing is the first process in cable production. First, copper or aluminum rods are placed in a wire drawing machine. Using one or more drawing dies, tension is applied to them at room temperature, which reduces the cross-section of the rod, increases its length, and improves its strength. During wire drawing, the die matching technology must be strictly controlled to ensure the dimensional accuracy of the wire. During the wire drawing process, the wire drawing machine must be kept running stably. The guide rollers between each drawing die keep the conductor under tension. After the wire drawing is completed, the wire is wound onto a reel to prepare for subsequent processes.

[0022] Stranding process; The stranding process is to improve the flexibility of the cable by stranding multiple copper or aluminum monofilaments into a round or polygonal conductor at a certain pitch according to the cable specifications. During the stranding process, the stranding pitch and stranding direction must be strictly controlled to ensure the conductor compactness and electrical performance. At the same time, in order to reduce the area occupied by the conductor and reduce the geometric size of the cable, a compaction method is often used to transform ordinary round conductors into semi-circles, fan shapes, tile shapes, and compacted round shapes to meet the needs of different cables.

[0023] The cabling process involves twisting multiple insulated cores into a circle to ensure cable shape and reduce overall size. The twisting mechanism is similar to conductor stranding. Due to the larger strand diameter, a non-twist method is mostly used. During cabling, it is necessary to prevent irregularly shaped insulated cores from turning over and causing cable bending, and to prevent the insulation layer from being scratched. At the same time, to ensure the roundness and stability of the cable after cabling, filling is performed, and to ensure that the cable cores do not become loose, binding is performed.

[0024] Crosslinking process; The crosslinking process is a key step in the production of crosslinked cables. Through chemical or physical crosslinking, the molecular chains of the insulating material undergo a crosslinking reaction to form a three-dimensional network structure. Crosslinking treatment can improve the heat resistance, mechanical strength and electrical insulation performance of the insulating material.

[0025] Degassing process: The degassing process involves heating the insulated core to volatilize cross-linking byproducts and eliminate insulation stress. Generally, the cable is heated to 70 degrees Celsius and held for seven days, followed by cooling for three days. A dedicated degassing oven can provide a stable temperature environment to ensure the degassing effect. After degassing, the cable insulation layer performance is more stable, which can reduce potential faults during operation and improve the cable's service life and reliability.

[0026] The wrapping process requires the preparation of tools and materials, such as a constant tension wrapping machine and an infrared thermometer. The ambient humidity should be controlled at ≤45%RH and the temperature at 22±3℃. The conductor is stripped in a stepped manner and the surface is polished. The sandwich structure method is used for wrapping. The inner semiconductor layer is wrapped with semiconducting tape at a 45° angle. The overlap rate of the main insulation layer is ≥50%. The tension is controlled at 2.5~3.0N / cm². The outer shielding layer copper mesh is wrapped with a 5mm expansion allowance. At the same time, the temperature curve is controlled to ensure the wrapping quality.

[0027] Argon arc welding process flow: The argon arc welding process is operated by a designated person. Before starting work, check whether the equipment, tools, welding power supply, control system, welding torch, ground wire, high-frequency arc ignition system, welding system, etc. are normal. Select the polarity according to the workpiece material, connect the welding circuit, check whether the welding bevel is qualified, and check the preheating equipment and temperature measuring instrument for workpieces that require preheating. During welding, the operating button must not be far from the arc. When using high-frequency arc ignition, leakage should be checked frequently. If the equipment fails, it should be shut down for repair, and the work area should be well ventilated.

[0028] The outer sheath process involves the following steps: First, raw material preparation is performed. Commonly used materials include thermoplastic or thermosetting polymers such as polyethylene. The raw material is placed into an extruder, where it is heated and rotated to mix and transport the material. The melted material is then passed through the die head to form the required cross-sectional shape and coat the cable surface. During the extrusion process, parameters such as extruder temperature, speed, and pressure must be controlled. Afterward, the extruded sheath is cooled in a cooling water tank to rapidly cool and solidify. The elongation and shrinkage rate of the sheath, as well as its physical properties, can be controlled by adjusting parameters such as linear speed and cooling water temperature.

[0029] Packaging Process: The packaging process is carried out after the cable's various technical indicators have passed inspection. First, the cable rolls are placed into plastic bags and sealed to prevent moisture and damage during transportation, storage, and use. Then, the corresponding cable model, production date, safety certification, and other markings are engraved on the sheath for easy user identification and use. After packaging, the cables are neatly stored and await shipment, ensuring that the cables remain in good condition before delivery to the customer. The traction mechanism 5 includes two sets of symmetrically designed outer shells 51 located inside the work area 4. A motor 52 is installed on one side of the outer shell 51. Two sets of transmission rollers 53 are rotatably connected to the inner wall of the outer shell 51, and one side of the transmission rollers 53 is fixedly connected to the output end of the motor 52. A track 54 is rotatably connected to the outer side of the transmission rollers 53. Two sets of limiting rollers 55 are rotatably connected to the inner wall of the outer shell 51. The outer shell 51 serves as the main structure of the traction mechanism 5, providing installation positions and protection for other components. The motor 52 provides power to the transmission rollers 53, which are driven to rotate by the motor 52, thus driving the track 54 to move. The track 54 is in direct contact with the cable, and the cable is propelled forward by friction to achieve the traction function. The limiting rollers 55 limit the cable, preventing it from deviating from the predetermined position during traction and ensuring that the cable can accurately pass through each production device.

[0030] The adjustment mechanism 6 includes a support frame 61 fixed to the inner wall of the work chamber 4. A vertically arranged threaded rod 62 is rotatably connected to the inner wall of the support frame 61. A first movable block 63 is installed on one side of the outer shell 51 by screws, and the inner wall of the first movable block 63 is threadedly connected to the outer side of the threaded rod 62. It should be noted that the top end of the threaded rod 62 penetrates the top of the work chamber 4 and extends to its outer side. A turntable is fixed to the top end of the threaded rod 62. The support frame 61 provides an installation position and support for the threaded rod 62. By rotating the turntable at the top end of the threaded rod 62, the threaded rod 62 is driven to rotate. The rotation of the threaded rod 62 enables the first movable block 63 to move up and down, thereby driving the outer shell 51 and the entire traction mechanism 5 to move up and down, which is used to adjust the position of the traction mechanism 5.

[0031] Both the pay-off frame 1 and the take-up frame 7 have support seats 16 fixed to their inner walls with screws. A transmission rod 17 is rotatably connected to the top of the support seat 16. One end of each transmission rod 17 is fixedly connected to the shaft center of the take-up roller 8 via a flange and the unwinding roller 2, respectively. The support seats 16 provide an installation position and support for the transmission rods 17, ensuring their stable rotation. The transmission rods 17 also support the unwinding roller 2 and the take-up roller 8. A fixing frame 18 is fixed to one side of both the pay-off frame 1 and the take-up frame 7. The bottom of the fixing frame 18 is fixed with… The limiting frame 19 is used to limit the cable body 3. The inner wall of the limiting frame 19 is rotatably connected to the roller 20. The fixed frame 18, the limiting frame 19 and the roller 20 are used in conjunction to facilitate the limiting of the cable body 3, prevent the cable from deviating during the unwinding or winding process, and ensure that the cable can accurately enter or leave the unwinding roller 2 or the winding roller 8. The roller 20 contacts the cable body 3, reducing the friction between the cable and the limiting frame 19, so that the cable can pass through the limiting frame 19 smoothly, and at the same time, it helps to protect the cable surface from damage.

[0032] A rotating rod 21 is rotatably connected to the shaft of the drive roller 53, and the outer side of the rotating rod 21 is slidably connected to the inner wall of the outer casing 51. A horizontally arranged screw 22 is fixed to the outer side of the rotating rod 21. A positioning block 23 is fixed to the outer side of the outer casing 51, and the inner wall of the positioning block 23 is rotatably connected to the inner wall of the screw 22. A locking block 24 is threadedly connected to the outer side of the screw 22. The rotating rod 21 provides rotational support for the drive roller 53 and allows the drive roller 53 to be adjusted within a certain range. When the position of the drive roller 53 needs to be adjusted, the locking block 24 is rotated, causing the locking block 24 to move along the outer side of the screw 22. Due to the restriction of the positioning block 23, when the locking block 24 is rotated again, the screw 22 will move along the threaded groove on the inner wall of the locking block 24, thereby driving the drive roller 53 to move through the rotating rod 21, and thus adjusting the tension of the track 54.

[0033] Two sets of second movable blocks 25 are fixed to one side of the outer casing 51 by screws. Two sets of vertically arranged limiting rods 26 are fixed to the inner wall of the working chamber 4. The outer side of the limiting rods 26 is slidably connected to the inner wall of the second movable blocks 25. The second movable blocks 25 and the limiting rods 26 work together to guide the up and down movement of the traction mechanism 5, ensuring that the traction mechanism 5 can move smoothly and accurately during the adjustment of its position.

[0034] The inner walls of workshop 4 are respectively equipped with a first cable wrapping machine 27 and a second cable wrapping machine 28, which are symmetrically designed. These machines allow for cable wrapping operations, encasing various wrapping tapes or sheathing materials on the cable surface to increase its mechanical strength and insulation performance, meeting different usage requirements. The symmetrical design may be for implementing different wrapping processes or improving production efficiency. Inside workshop 4, a first dehumidifier heater 29 and a second dehumidifier heater 30 are respectively installed. The first dehumidifier heater 29 is located to one side of the second cable wrapping machine 28, and the second dehumidifier heater 30 is located below the take-up frame 7. The first dehumidifier heater 29's location to one side of the second cable wrapping machine 28 allows for dehumidification and heating of the wrapped cable. The first dehumidifier 27 and the second dehumidifier 28 in this case are located below the take-up frame 7 to remove moisture that may be introduced during the wrapping process. They are used to dehumidify and heat the cable before it is wound up, ensuring that the cable is dry before winding and improving product quality. It should be noted that the working principle of the first wrapping head machine 27 and the second wrapping head machine 28 in this case is the same as the working principle of the wrapping machine in a coaxial production system for wires and cables in the authorized application number CN201720723729.0. They are existing technologies and will not be described in detail here. At the same time, the working principle of the first dehumidifier 29 and the second dehumidifier 30 in this case is the same as the working principle of the heater in a production device for flexible mineral insulated fireproof cables in the authorized application number CN202121990033.7. They are existing technologies and will not be described in detail here.

[0035] The present invention also provides a method for using a dehumidification device and its application method in the cable wrapping production process, including the following steps: S1, Preliminary preparation and equipment installation: The wire feeding frame 1 and the wire take-up frame 7 are placed securely in a suitable position in the production area. Using the support base 16 and the transmission rod 17, the unwinding roller 2 is installed on the inner wall of the wire feeding frame 1 and the take-up roller 8 is installed on the inner wall of the take-up frame 7 through the flange, ensuring that the unwinding roller 2 and the take-up roller 8 can rotate smoothly. Then, the cable body 3 is wound on the unwinding roller 2. The cable body 3 consists of the cable conductor 9, conductor shield 10, insulation layer body 11, insulation shield layer 12, buffer layer 13, metal sheath layer 14 and non-metallic sheath 15 from the inside out. Each layer is tightly wrapped to form the cable protection system. A fixing frame 18 is installed on one side of the wire feeding frame 1 and the take-up frame 7, and a limiting frame 19 is fixed at the bottom of the fixing frame 18. The inner wall of the limiting frame 19 is rotatably connected to the roller 20 to limit the cable body 3 and prevent it from deviating during transmission. S2. Cable Traction and Position Adjustment: Activate the motor 52 in the traction mechanism 5. The motor 52 drives the transmission roller 53 to rotate, and the track 54 rotates accordingly to achieve cable traction. The limiting roller 55 can further limit the cable to ensure the stability of the traction process. If it is necessary to adjust the position of the traction mechanism 5, rotate the threaded rod 62 in the adjustment mechanism 6. Since the first movable block 63 is threadedly connected to the threaded rod 62 and the first movable block 63 is installed on one side of the housing 51, the housing 51 will move up and down accordingly, thereby changing the position of the traction mechanism 5. The second movable block 25 on one side of the housing 51 slides on the limiting rod 26 to provide guidance for the movement of the housing 51 and ensure smooth movement. S3. Wrapping and Dehumidification Operation: The cable enters the working chamber 4 via the traction mechanism 5. It first undergoes preliminary wrapping by the first wrapping head machine 27 to add a layer of protection to the cable. Then, the cable reaches the second wrapping head machine 28 for re-wrapping to further enhance the cable's protective performance. During the wrapping process, the first dehumidifying heater 29 is located on one side of the second wrapping head machine 28 to perform preliminary dehumidification on the cable after preliminary wrapping, removing some moisture from the surface and inside of the cable. Afterward, the second dehumidifying heater 30 is located below the take-up frame 7 to perform deep dehumidification on the cable after re-wrapping, ensuring that the cable is completely dry. S4. Component maintenance and adjustment during production: If it is necessary to adjust the spacing of the transmission rollers 53 during production, the locking block 24 on one side of the positioning block 23 can be rotated. The locking block 24 moves along the outside of the screw 22. Due to the obstruction of the positioning block 23, the locking block 24 cannot move. At this time, the screw 22 will continue to move along the inner wall of the locking block 24, which will drive the rotating rod 21 and the transmission rollers 53 to move.

[0036] Working Principle: In the cable wrapping production process, the cable body 3 wound on the unwinding roller 2 is first unwound. The unwound cable body 3 is initially limited by the roller 20 in the limiting frame 19 on one side of the unwinding frame 1 to ensure that the cable smoothly enters the subsequent process. Then, the cable body 3 enters the working chamber 4. In the traction mechanism 5, the motor 52 drives the transmission roller 53 to rotate, and the transmission roller 53 drives the track 54 to rotate. At the same time, the limiting roller 55 plays an auxiliary limiting and guiding role for the cable body 3, so that the cable can be stably pulled forward. In order to accommodate different specifications of cable body 3, the position of the traction mechanism 5 can be adjusted by the adjustment mechanism 6. By rotating the turntable at the top of the threaded rod 62, the threaded rod 62 can be driven to rotate. The threaded rod 62 drives the first movable block 63 to move up and down. The first movable block 63 drives the outer shell 51 to move up and down, thereby adjusting the position of the traction mechanism 5. At the same time, the second movable block 25 on one side of the outer shell 51 and the working chamber 4 are in contact with each other. The limiting rod 26 on the inner wall is slidably connected to ensure the stability of the outer shell 51. During the pulling process of the cable body 3, the first wrapping machine 27 and the second wrapping machine 28 symmetrically wrap the cable to add the necessary protective layer to the cable. The wrapped cable needs to be dehumidified. The first dehumidifier 29 set in the work area 4 is located on one side of the second wrapping machine 28, and the second dehumidifier 30 is located below the take-up frame 7. When the cable passes through the first dehumidifier 29 and the second dehumidifier 30, the heat generated by the heaters evaporates the moisture on the surface and inside of the cable, achieving the purpose of dehumidification. Finally, the dehumidified cable body 3 is pulled to the take-up frame 7. The take-up roller 8 is rotatably connected to the support seat 16 on the inner wall of the take-up frame 7 through the transmission rod 17 to take up the dehumidified cable. Similarly, the limiting frame 19 and roller 20 on one side of the take-up roller 8 provide the final limit for the cable to ensure neat winding. Thus, the dehumidification process of the cable wrapping production process is completed.

10. A method for dehumidifying a cable wrapping production process, applied to the dehumidifying device for the cable wrapping production process as described in any one of claims 1-9, characterized in that: Includes the following steps: S1. Preliminary preparation and equipment installation: Place the pay-off frame (1) and take-up frame (7) securely in a suitable position in the production area. Using the support base (16) and transmission rod (17), install the unwinding roller (2) on the inner wall of the pay-off frame (1) and the take-up roller (8) on the inner wall of the take-up frame (7) through the flanges. Ensure that the unwinding roller (2) and the take-up roller (8) can rotate smoothly. Then, wind the cable body (3) around the unwinding roller (2). The cable body (3) consists of the cable conductor (9) and conductor (9) from the inside out. The cable consists of a shield (10), an insulation layer (11), an insulation shield layer (12), a buffer layer (13), a metal sheath layer (14), and a non-metallic sheath (15). Each layer is tightly wrapped and together constitutes the cable's protection system. A fixing frame (18) is installed on one side of the cable release frame (1) and the cable take-up frame (7), and a limiting frame (19) is fixed at the bottom of the fixing frame (18). The inner wall of the limiting frame (19) is connected to a roller (20) to limit the cable body (3) and prevent it from deviating during transmission. S2, Cable Traction and Position Adjustment: Turn on the motor (52) in the traction mechanism (5). The motor (52) drives the transmission roller (53) to rotate, and the track (54) rotates accordingly to achieve cable traction. The limit roller (55) can further limit the cable to ensure the stability of the traction process. If the position of the traction mechanism (5) needs to be adjusted, rotate the threaded rod (62) in the adjustment mechanism (6). Since the first movable block (63) is threadedly connected to the threaded rod (62) and the first movable block (63) is installed on one side of the outer shell (51), the outer shell (51) will move up and down accordingly, thereby changing the position of the traction mechanism (5). The second movable block (25) on one side of the outer shell (51) slides on the limit rod (26) to provide guidance for the movement of the outer shell (51) and ensure smooth movement. S3. Wrapping and Dehumidification Operation: The cable enters the working room (4) through the traction mechanism (5). It first passes through the first wrapping head machine (27) for preliminary wrapping to add a layer of protection to the cable. Then, the cable reaches the second wrapping head machine (28) for re-wrapping to further enhance the cable's protective performance. During the wrapping process, the first dehumidifying heater (29) is located on one side of the second wrapping head machine (28) to perform preliminary dehumidification on the cable after preliminary wrapping, removing some moisture from the surface and inside of the cable. Afterward, the second dehumidifying heater (30) is located below the take-up frame (7) to perform deep dehumidification on the cable after re-wrapping to ensure that the cable is completely dry. S4. Component maintenance and adjustment during production: If it is necessary to adjust the spacing of the transmission roller (53) during production, the locking block (24) on one side of the positioning block (23) can be rotated. The locking block (24) moves along the outside of the screw (22). Due to the obstruction of the positioning block (23), the locking block (24) cannot be displaced. At this time, the screw (22) will continue to be displaced along the inner wall of the locking block (24), which will drive the rotating rod (21) and the transmission roller (53) to move.
