Description

Technical Field

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

[0002] Wires and cables are wire products used to transmit electrical energy, information, and realize electromagnetic energy conversion. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated cores, and their respective possible sheaths, overall protective layers, and outer sheaths. Cables may also have additional uninsulated conductors. During the cable production process, after the outer sheath is formed, it needs to be dried to remove moisture for the convenience of subsequent processes and storage.

[0003] Existing cable production drying equipment typically uses hot air to heat and dry the outside of the cable. This method is simple in structure, but its drying method is singular, resulting in low drying efficiency for cables. In addition, the equipment requires cumbersome adjustments during use to make it suitable for different cables, reducing its practicality. Therefore, it is necessary to design and modify the surface drying equipment for cable production to effectively prevent the problems of low drying efficiency and inconvenience in use.

[0015] 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 protection scope of the present utility model.

[0016] like Figures 1 to 4As shown, a surface drying device for cable production includes a water collection tank 1. Slide grooves are provided on both the front and back sides of the water collection tank 1, and movable frames 2 are slidably connected inside the slide grooves. Support rollers 3 are rotatably connected between the front and rear movable frames 2. Electric cylinders 4 are fixedly connected to both the front and back sides of the water collection tank 1, and the output ends of the electric cylinders 4 are fixedly connected to the movable frames 2. A support frame 5 is fixedly connected to the surface of the water collection tank 1, and a turntable 6 is rotatably connected inside the support frame 5. A first motor 8 is fixedly connected to the right side of the support frame 5, and the output end of the first motor 8 is fixedly connected to the turntable 6. An opening 7 is provided on the left side of the turntable 6, and the number of openings 7 is [number missing]. The openings 7 are evenly distributed in a ring on the left side of the turntable 6, and the diameter of each opening 7 is different. A ring frame 9 is fixedly connected to the surface of the water collection tank 1 by a bracket. A nozzle 10 is fixedly connected to the inner wall of the ring frame 9. There are several nozzles 10, which are evenly distributed in a ring on the inner wall of the ring frame 9. A bellows 11 is fixedly connected to the right side of the front of the water collection tank 1. A fan is fixedly connected to the inside of the bellows 11 by a bracket. An electric heating wire is fixedly connected to the inside of the bellows 11. The electric heating wire is located above the fan. An air outlet pipe 12 is connected to the top of the bellows 11. The air outlet pipe 12 is connected to the nozzles 10 by a distributor.

[0017] refer to Figure 3 Both sides of the surface of the water collection tank 1 are fixedly connected to a fixed frame 14. The top of the inner wall of the fixed frame 14 is fixedly connected to a drive box 15. The front and rear sides of the drive box 15 are slidably connected to movable columns 16. The drive box 15 is rotatably connected to a threaded rod with positive and negative threads. The threaded rod with positive and negative threads is threadedly connected to the movable column 16. The front of the drive box 15 is fixedly connected to a second motor 18. The output end of the second motor 18 is fixedly connected to the threaded rod with positive and negative threads. Guide rollers 17 are fixedly connected to the adjacent sides of the two movable columns 16.

[0018] As a technical optimization of this utility model, by setting a fixed frame 14, a drive box 15, a threaded rod with positive and negative threads and a movable column 16 on the surface of the water collection tank 1, the second motor 18 drives the threaded rod with positive and negative threads to rotate. By utilizing the characteristics of the positive and negative threads, the two movable columns 16 move synchronously towards or away from each other, thereby driving the guide roller 17 fixed on the movable column 16 to adjust the spacing. This can accurately adapt to the guiding requirements of cables of different diameters, avoiding the problem of frequent component replacement due to the fixed guiding structure of traditional devices, and further enhancing the adaptability of the device to cables of different specifications.

[0019] refer to Figure 3 The drive box 15 has a bearing fixedly connected inside, and the outer ring of the bearing is fixedly connected to the drive box 15, while the inner ring of the bearing is fixedly connected to the threaded rod.

[0020] As a technical optimization of this utility model, the frictional resistance during the rotation of the positive and negative threaded rod is effectively reduced by the setting of the bearing inside the drive box 15, making the adjustment process of the guide roller 17 smoother and more stable, reducing energy consumption and wear during equipment operation, extending the service life of the device, and improving the overall reliability and stability of operation.

[0021] refer to Figure 1 A drain valve is connected to the right side of the water collection tank 1.

[0022] As a technical optimization of this utility model, a drain valve is designed to connect to the right side of the water collection tank 1, which can promptly drain the wastewater dripping during the cable surface scraping or drying process. Traditional devices, due to the lack of a drainage structure in the water collection tank 1, allow wastewater to stagnate for extended periods, easily breeding bacteria and corroding the tank body. This design, however, uses a drain valve to periodically empty the water collection tank 1, preventing residual wastewater from corroding the tank material and internal metal components such as the support roller 3 and movable frame 2, thus extending the service life of the water collection tank 1. Simultaneously, the drainage operation cleans up impurities deposited at the bottom of the tank, preventing them from adhering to the surface with the moving cable and affecting the drying effect. This ensures the device maintains a clean working environment, further improving the quality stability of the drying process and the convenience of equipment maintenance.

[0023] refer to Figure 1 A dustproof plate 13 is slidably connected inside the air box 11. The front of the dustproof plate 13 extends to the front of the air box 11 and is fixedly connected to a handle. The surface of the handle is provided with anti-slip texture, and the number of anti-slip textures is several. The dustproof plate 13 is located below the fan, and the surface of the fan motor is provided with a protective cover.

[0024] As a technical optimization of this utility model, a sliding dustproof plate 13 is installed inside the air box 11, which can be quickly pulled out via a handle on the front. When the device is running, the dustproof plate 13 can effectively prevent external dust, fibers, and other impurities from entering the air box 11, avoiding impurities adhering to the fan blades and increasing rotational resistance, or covering the surface of the electric heating wire and affecting heat transfer efficiency. When maintenance is required, the inside of the air box 11 can be directly cleaned by pulling out the dustproof plate 13 via the handle. Compared with the traditional closed air box 11, which requires disassembling the outer shell for maintenance, this significantly reduces the difficulty of cleaning. This design not only ensures stable air delivery from the fan and uniform heating of the electric heating wire, ensuring that the temperature and flow rate of the hot air ejected from the nozzle 10 meet the drying requirements, but also reduces equipment failures caused by impurity accumulation, improving the continuity of device operation and the stability of the drying effect.

[0025] refer to Figure 2 A rubber squeegee ring 19 is fixedly connected to the inner wall of the opening 7.

[0026] As a technical optimization of this utility model, a rubber squeegee ring 19 is designed and fixedly connected to the inner wall of the through-hole 7 of the turntable 6. The rubber squeegee ring 19 is made of soft and elastic material, allowing it to closely conform to the surface of cables of different diameters. When the cable passes through the through-hole 7, the rubber squeegee ring 19 can first scrape off most of the moisture adhering to the surface, creating a "pre-drying" effect and reducing the amount of water evaporated required for subsequent hot air drying. Simultaneously, the ring-shaped structure of the squeegee ring can apply pressure evenly, preventing deformation of the cable's outer sheath due to excessive local pressure, thus ensuring the cable's appearance quality.

[0027] The working principle and usage process of this utility model are as follows: When using this surface drying device for cable production, select a matching diameter opening 7 on the turntable 6 according to the diameter specifications of the cable to be dried. The turntable 6 has several openings 7 of different diameters, and each opening 7 has a rubber scraper ring 19 fixed to its inner wall to accommodate cables of different diameters. Activate the electric cylinders 4 on both the front and back sides of the water collection tank 1. The output end of the electric cylinder 4 pushes the movable frame 2 to slide up and down along the slide groove. Adjust the height of the two movable frames 2 so that the highest point of the support roller 3 is level with the lowest point of the selected opening 7. The support roller 3 is located between the front and rear movable frames 2 and can rotate freely, supporting the cable and guiding it smoothly through the opening 7. Before the cable enters the drying area, its travel path needs to be calibrated using guide rollers 17. The second motor 18 on the front of the drive box 15 is started, and its output drives the threaded rods to rotate. Since the threaded rods are threadedly connected to the movable columns 16, and the movable columns 16 are slidably connected to both the front and rear sides inside the drive box 15, when the threaded rods rotate, the two movable columns 16 move synchronously towards each other, thereby causing the two guide rollers 17 to move closer together. The spacing between the guide rollers 17 is adjusted by rotating the second motor 18 in both directions, ensuring the cable passes centered between the two guide rollers 17 and preventing forward / backward deviation. The guide rollers 17 can rotate. After completing the above preparations, the cable to be dried is introduced from the left side of the device, passing sequentially through the left support roller 3, the two left front and rear guide rollers 17, the turntable 6 through-hole 7, the two right front and rear guide rollers, and the right support roller 3. When the cable passes through through-hole 7, the rubber scraper ring 19 on the inner wall will first contact the cable surface, using its soft elasticity to tightly adhere to the cable and scrape off most of the water adhering to the surface, achieving preliminary physical dehydration. The scraped water droplets fall into the water collection tank 1. At this time, the first motor 8 is started, and its output end drives the turntable 6 to rotate. If it is necessary to change the through-hole 7 later, it can be switched to other diameter through-hole 7 by rotating the turntable 6 to adapt to the continuous production needs of cables of different specifications. The first motor 8 is a servo motor. The fan and heating element inside the air box 11 are then activated. The fan draws in outside air, which is heated as it passes through the heating element, creating dry hot air. The hot air enters the distributor through the outlet pipe 12 at the top of the air box 11 and is then evenly distributed to several nozzles 10 on the inner wall of the circular frame 9. Each nozzle 10 has its outlet slightly tilted to the right. The nozzles 10 are aligned with the cable's travel direction, creating a co-current drying effect and improving hot air utilization. The nozzles 10 are evenly distributed in a ring, allowing hot air to be sprayed onto the cable surface from multiple angles, providing comprehensive hot air drying for the cable after the initial treatment with the scraper ring. The fan provides stable airflow, and the heating element can adjust its heating power according to drying requirements, ensuring the hot air temperature is suitable for efficient drying.
