Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically a cable surface dehydration device. Background Technology

[0002] During the cable manufacturing process, moisture or water can easily adhere to the cable surface. In order to ensure that the cable remains dry during production and use, thereby improving the cable's quality and service life, a dehydration device is needed to remove the moisture from the cable surface.

[0003] Chinese patent application CN 119028674 A discloses a cable surface dewatering device for a cable production line, belonging to the field of cable production technology. It includes a support frame and a cable body. A lower housing is fixedly mounted on the upper end of the support frame. An upper housing is hinged to one side of the upper end of the lower housing via a reset hinge. A groove for placing the cable body is formed between the lower and upper housings. A dewatering component for removing water from the cable surface is provided inside the lower housing. The beneficial effects of this invention are: by setting a moving plate, lead screw, ring, fixing sleeve, dewatering strip, gear, and gear ring, the moving plate first moves to the middle of the lower housing and is fixed. Then, the dewatering strip wraps around the surface of the cable body, so that when the cable body is pulled to move, the surface of the cable body is thoroughly dewatered, effectively ensuring the dewatering effect of the cable body.

[0004] Existing dewatering devices typically use spring-loaded scrapers to remove water from the cable surface. However, these scrapers may apply uneven pressure to the cable, which can easily scratch the cable sheath after prolonged use, resulting in poor cable protection. Therefore, a cable surface dewatering device is proposed to address these issues. Utility Model Content

Gears are fixedly fitted on the rotating shafts of the conveying wheels, and the two gears mesh with each other. A drive motor is mounted on the bottom side of the fixed frame via a base, and the output shaft of the drive motor is fixedly connected to one of the rotating shafts. A cable is placed between the two conveying wheels. A scraper removes water stains from the surface of the cable. During this process, the scraper is slidably connected to a guide plate, and according to the change in the diameter of the cable surface, the cable can push the scraper to slide on the guide plate. Under the action of a spring, the scraper is always in contact with the cable surface to remove water. This structure, by setting a scraper array that adapts to changes in cable diameter, avoids uneven pressure on the swollen parts of the cable, which could cause scratches on the cable sheath, thus improving the protection of the cable.

[0007] Preferably, an air blowing assembly is installed on the support base. The air blowing assembly includes a fan. The fan is fixedly installed on the side wall of the support base, and an air guide pipe is installed on the fan. The other end of the air guide pipe is connected to an air blowing cylinder. The air blowing cylinder is fixedly installed on the support base. An air chamber is formed inside the side plate of the air blowing cylinder. A heating plate with a mesh structure is installed on the inner wall of the air chamber. Multiple Venturi tubes are installed on the inner wall of the air blowing cylinder. Each Venturi tube includes a contraction tube, a throat, and a diffuser. One end of the contraction tube is fixedly connected to the inner wall of the blowing cylinder, the other end of the contraction tube is fixedly connected to the throat, and the other end of the throat is fixedly connected to the diffuser. After the cable is scraped clean by the scraper assembly, water stains may remain on the cable surface. The cable then enters the air blower, where a fan guides cold air into the air duct. This cold air is heated by a heating plate and then ejected from the venturi tubes, effectively drying the cable surface. During this process, the venturi tubes at the hot air nozzles accelerate the airflow; the array of multiple venturi tubes allows for 360° coverage of the cable surface with high-speed airflow, resulting in thorough and efficient water removal and improving the overall efficiency of the air blowing process.

According to the change in the diameter of the cable surface, the cable can push the scraper to slide on the guide plate. Under the action of the spring, the scraper is always in contact with the cable surface to remove water. This structure, by setting a scraper array that adapts to the change in cable diameter, avoids uneven pressure on the swollen parts of the cable, which could cause scratches on the cable sheath and improves the protection of the cable.

[0010] 2. In this invention, after the cable is scraped clean by the scraper component, water stains may remain on the cable surface.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1-4As shown, a cable surface dewatering device includes a support base 1, a PLC controller 2 mounted on the side wall of the support base 1, a scraping assembly mounted on the support base 1, the scraping assembly including a cavity, a cavity opened inside the support base 1, a water collection tank 3 provided on the top plate of the cavity of the support base 1, a drain hole 301 opened on the support base 1 at the water collection tank 3, a drain pipe 302 mounted on the side wall of the cavity, a valve mounted on the drain pipe 302, multiple mounting brackets 303 mounted on the water collection tank 3, and guide plates 304 mounted on the mounting brackets 303. A groove 305 is provided inside the 304, and a slider 306 is assembled inside the groove 305. A spring 307 is installed between the slider 306 and the inner wall of the groove 305. A connecting block 308 is installed on the slider 306, and a scraper 309 is installed on the connecting block 308. A conveying assembly is installed on the support base 1. Two sets of conveying assemblies are provided. The conveying assembly includes a fixed frame 4. Two conveying wheels 401 are rotatably mounted on the fixed frame 4 via a rotating shaft. Gears 402 are fixedly sleeved on the rotating shaft of the conveying wheels 401. The two gears 402 mesh with each other. A drive motor 403 is mounted on the bottom side via a base. The output shaft of the drive motor 403 is fixedly connected to one of the rotating shafts. A cable 6 is placed between the two conveying wheels 401. During operation, existing dewatering devices typically use a spring-loaded scraper 309 to remove water from the surface of the cable 6. The spring-loaded scraper 309 may exert uneven pressure on the cable 6, and after prolonged use, it is easy to scratch the outer sheath of the cable 6, resulting in poor protection of the cable 6. By operating two sets of conveying components, the drive motor 403 rotates, driving one of the rotating shafts to rotate. One of the rotating shafts drives the gear 402 on it to rotate, and the gear 402 drives the other gear 402 to rotate. That is, the two gears 402 rotate synchronously relative to each other, and the two gears 402 drive the two rotating shafts to rotate synchronously relative to each other. The two rotating shafts drive the two conveying wheels 401 to rotate synchronously relative to each other, and the two conveying wheels 401 push the cable 6 to move horizontally. This enables the cable 6 to move horizontally within the scraping component and the air blowing component. Since the structure of the conveying components is fixed, the dewatering device is only suitable for cables 6 of one diameter.

[0021] During the manufacturing process of cable 6, the change in the surface diameter of cable 6 may be caused by a variety of factors, such as extrusion molding defects, material shrinkage differences, and wrapping process problems. The change in the surface diameter of cable 6 can be manifested as local swelling or shrinkage of the surface of cable 6.

[0022] When cable 6 passes over the scraping assembly, the scraper 309, made of carbon fiber composite material, consists of multiple scraper 309 arrays that contact the top, left, right, and bottom sides of the cable 6 surface to thoroughly scrape away water stains. The scraped water flows from the water collection tank 3 into the cavity of the support base 1 and is finally discharged from the drain pipe 302. During this process, the scraper 309 is slidably connected to the guide plate 304, and according to the diameter change of the cable 6 surface, the cable 6 can push the scraper 309 to slide on the guide plate 304. Under the action of the spring 307, the scraper 309 is always in contact with the surface of the cable 6 to scrape water. This structure, by setting an array of scraper 309 that adapts to the diameter change of the cable 6, replaces the spring-type scraper 309, avoiding uneven pressure on the swollen parts of the cable 6 and causing scratches on the outer sheath of the cable 6, thus improving the protection of the cable 6.

[0023] Please see Figure 5-6As shown, an air blowing assembly is installed on the support base 1. The air blowing assembly includes a fan 5. The fan 5 is fixedly installed on the side wall of the support base 1. An air guide pipe 501 is installed on the fan 5. The other end of the air guide pipe 501 is connected to an air blowing cylinder 502. The air blowing cylinder 502 is fixedly installed on the support base 1. An air chamber 503 is opened inside the side plate of the air blowing cylinder 502. A heating plate 504 with a mesh structure is installed on the inner wall of the air chamber 503. Multiple Venturi tubes 505 are installed on the inner wall of the air blowing cylinder 502. Each Venturi tube 505 includes a converging tube 506, a throat 507, and a diffuser 508. One end of the shrink tube 506 is fixedly connected to the inner wall of the blower 502, and the other end of the shrink tube 506 is fixedly connected to the throat 507. The other end of the throat 507 is fixedly connected to the diffuser 508. During operation, existing dewatering devices typically use air blowing to remove water from the surface of the cable 6. However, the airflow is weak, resulting in poor efficiency. After the cable 6 passes through the scraping assembly and is scraped by the scraper 309 to remove water stains, water stains still remain on the surface of the cable 6. The cable 6 then enters the blower 502 and is operated by the fan 5 (model 4-72N). At 0.3.6F, the fan 5 guides cold air into the air duct 501. The cold air enters the air chamber 503 of the air blower 502, where it is heated by the heating plate 504 and then ejected from the Venturi tube 505 to dry the surface of the cable 6. During this process, the Venturi tube 505, installed at the hot air nozzle, accelerates the airflow. The Venturi effect refers to the physical phenomenon where the flow velocity increases and the static pressure decreases when a fluid passes through the constriction section of a pipe. As an airflow enhancement structure, the Venturi tube 505 includes a constriction tube 506 and a throat 507. The diffuser 508 has a gradually decreasing cross-sectional area of ​​the contraction tube 506, which accelerates the airflow and reduces the pressure, smoothly guiding the airflow to the throat. The throat 507 has the smallest cross-sectional area and the airflow velocity reaches its maximum. The starting end of the diffuser 508 is a jet nozzle, from which high-velocity hot air is ejected and directly impacts the surface of the cable 6, drying the surface of the cable 6. At the same time, multiple Venturi tubes 505 are arranged in an array, and the high-speed airflow can cover the surface of the cable 6 360°, achieving thorough and efficient water removal from the surface of the cable 6, which is beneficial to improving the efficiency of air blowing.

[0024] Working principle: Existing dehydration devices typically use a spring-loaded scraper 309 to remove water from the surface of cable 6. However, this scraper may apply uneven pressure to the cable 6, easily scratching the outer sheath after prolonged use, resulting in poor cable protection. This new device utilizes two sets of conveying components. A drive motor 403 rotates, driving one shaft, which in turn drives a gear 402. This gear 402 then drives another gear 402, resulting in synchronized relative rotation. This rotation, in turn, drives two shafts, which in turn drive two conveyor wheels 401, which in turn propel the cable 6 horizontally. This allows the cable 6 to move horizontally within the scraping and air-blowing components. Because the conveying components have a fixed structure, the dehydration device is only suitable for cables of one diameter. During the manufacturing process of the cable 6, variations in its surface diameter can occur due to various factors. Caused by factors such as extrusion molding defects, material shrinkage differences, and wrapping process issues, the change in the surface diameter of cable 6 manifests as localized swelling or shrinkage of the cable 6 surface. When cable 6 passes over the scraping assembly, multiple sets of scrapers 309 are arranged in an array, contacting the top, left, right, and bottom sides of the cable 6 surface respectively, to comprehensively scrape away water stains on the cable 6 surface. The scraped water flows from the water collection tank 3 into the cavity of the support base 1, and finally is discharged from the drain pipe 302. During this process, the scrapers 309 are slidably connected to the guide plate 304, and according to the change in the diameter of the cable 6 surface, the cable 6 can push the scrapers 309 to slide on the guide plate 304. Under the action of the spring 307, the scrapers 309 are always in contact with the surface of the cable 6 to scrape water from the cable 6 surface. This structure, by setting an array of scrapers 309 that adapts to the change in the diameter of the cable 6, replaces the spring-type scrapers 309, avoiding uneven pressure on the swollen parts of the cable 6 and causing scratches on the outer sheath of the cable 6, which is beneficial to improving the protection of the cable 6.Existing dehydration devices typically use air blowing to remove water from the surface of cable 6. However, the airflow is weak, resulting in poor efficiency. Even after the cable 6 passes through the scraping assembly and is scraped off by the scraper 309, water stains remain on its surface. The cable 6 then enters the air blowing cylinder 502, where it is operated by a fan 5 (model 4-72). No. 3.6F, the fan 5 introduces cold air into the air duct 501. The cold air enters the air chamber 503 of the air blower 502, where it is heated by the heating plate 504 and then ejected from the Venturi tube 505 to dry the surface of the cable 6. During this process, the Venturi tube 505, installed at the hot air nozzle, accelerates the airflow. The Venturi effect refers to the physical phenomenon where the flow velocity increases and the static pressure decreases when a fluid passes through the constriction section of a pipe. As an airflow enhancement structure, the Venturi tube 505 includes a constriction tube 506 and a throat 507. The diffuser 508 has a gradually decreasing cross-sectional area of ​​the contraction tube 506, which accelerates the airflow and reduces the pressure, smoothly guiding the airflow to the throat. The throat 507 has the smallest cross-sectional area and the airflow velocity reaches its maximum. The starting end of the diffuser 508 is a jet nozzle, from which high-velocity hot air is ejected and directly impacts the surface of the cable 6, drying the surface of the cable 6. At the same time, multiple Venturi tubes 505 are arranged in an array, and the high-speed airflow can cover the surface of the cable 6 360°, achieving thorough and efficient water removal from the surface of the cable 6, which is beneficial to improving the efficiency of air blowing.
