Description

Technical Field

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

[0002] Cables, as an indispensable infrastructure in modern electronics and power, typically consist of one or more insulated conductors encased in an insulation and protective layer. Their core function is to transmit information or electrical energy across space. Water cooling is a common process in cable manufacturing; however, this process can lead to a significant amount of moisture adhering to the cable surface. If this residual moisture is not effectively removed, it can not only affect subsequent processing steps (such as printing, testing, and packaging) but also accelerate cable aging or reduce insulation performance. Therefore, efficient and reliable cable surface dehydration equipment has become a crucial post-processing step in the production process.

[0003] Current technologies for removing moisture from cable surfaces generally rely on fixed nozzles or simple sweeping spraying methods. These methods have significant limitations: firstly, they struggle to achieve dynamic, uniform, and thorough cleaning of the circumferential surface of a high-speed moving cable using high-pressure airflow, resulting in noticeable cleaning blind spots; secondly, they lack sufficient impact force for strongly adhesive water stains or films, leading to less than ideal removal results. Even more challenging is that, under the influence of gravity and wind, moisture at the bottom of the cable easily accumulates into larger, more stubborn water stain clumps, making them even more difficult to remove completely using conventional spraying methods, thus becoming a persistent and difficult point in the dewatering process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where fixed nozzle spraying methods have obvious cleaning blind spots, and where moisture at the bottom of the cable easily accumulates to form larger and more stubborn water stains, making it more difficult to completely remove them using conventional spraying methods. Therefore, this invention proposes a cable surface dewatering device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable surface dehydration device is designed, including a support frame, sleeves on both sides of the top of the support frame, jetting components on the inner sides of the two sleeves, a fan assembly connected to one side of the support frame, and two connecting pipes on the top of the fan assembly, which respectively pass through the sleeves and are connected to the jetting components.

[0007] The jet assembly includes a cavity formed in the sleeve, the cavity being connected to a connecting pipe, and a rotating ring connected to the cavity via a sealed bearing. A plurality of nozzles are arranged on the inner side of the rotating ring in a circumferential arrangement around the rotating ring.

[0008] Preferably, each of the two rotating rings is provided with a rotating mechanism, the rotating mechanism including a rotating shaft placed on one side of the sleeve, the rotating shaft being connected to the sleeve through a sealed bearing, one end of which extends into the cavity, a friction ring being provided on the outer side of the rotating ring, a friction wheel being connected to one end of the rotating shaft, the friction ring cooperating with the friction wheel, and a drive assembly being provided in the middle of the top of the support frame, the output end of the drive assembly being connected to one end of the two rotating shafts.

[0009] Preferably, both the friction ring and the outer side of the friction wheel are provided with a nitriding layer.

[0010] Preferably, the drive assembly includes a fixed base installed in the middle of the support frame, a long shaft connected to one end of one of the rotating shafts, a motor installed at the bottom of the fixed base, a first bevel gear provided on the output end of the motor, and a second bevel gear provided on the outside of the long shaft, wherein the first bevel gear meshes with the second bevel gear.

[0011] Preferably, the transmission ratio between the first bevel gear and the second bevel gear is 5:1.

[0012] Preferably, the top of the fixing seat is provided with a sponge wheel assembly.

[0013] Preferably, a pipe is connected to one side of the top of the fan assembly, and a heating coil assembly is installed inside the pipe, with one end of one of the connecting pipes connected to one end of the pipe.

[0014] Preferably, the nozzles on the rotating ring are all arranged at an angle, with their spray axis forming a 30° angle with the horizontal plane.

[0015] The cable surface dehydration device proposed in this utility model has the following advantages:

[0016] 1. The powerful airflow generated by the fan assembly is delivered to the sleeve cavity through the pipeline, driving a specially designed rotating ring to rotate smoothly around the cable axis. The nozzles evenly installed on the rotating ring rotate synchronously, continuously spraying out high-speed, concentrated airflow jets. This rotating spray pattern dynamically and comprehensively washes the outer surface of the cable, efficiently stripping and removing adhering moisture or water stains.

[0017] 2. The motor drives the friction wheel through a bevel gear, a long shaft, and a rotating shaft. The friction wheel transmits power to the friction ring using a friction pair, which in turn drives the rotating ring and the nozzle to rotate. This multi-stage friction transmission structure utilizes controllable sliding characteristics to achieve precise adjustment and buffering of the nozzle speed, significantly reducing the risk of potential impact damage to the cable surface from high-speed airflow.

[0018] 3. The fan airflow can be heated by the heating coil to form hot air at a preset temperature, which is then sprayed out at high speed from the nozzle to accelerate the evaporation and removal of moisture from the cable surface. At the same time, the sponge wheel assembly squeezes and wipes away water stains on the bottom of the cable, assisting in the removal of water by the hot air. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: Refer to Figure 1-6 A cable surface dehydration device includes a support frame 1, sleeves 2 are provided on both sides of the top of the support frame 1, and jetting components are provided inside the two sleeves 2. A fan assembly 3 is connected to one side of the support frame 1, and two connecting pipes 4 are provided on the top of the fan assembly 3. The two connecting pipes 4 pass through the sleeves 2 and are connected to the jetting components.

[0028] The jet assembly includes a cavity 5 opened in the sleeve 2, which is connected to the connecting pipe 4. A rotating ring 6 is connected to the cavity 5 through a sealed bearing. Several nozzles 7 are arranged circumferentially around the rotating ring 6.

[0029] Working Principle: After the cable passes through the inside of two opposing sleeves 2, the fan assembly 3 is activated. The powerful airflow generated is delivered through pipe 17 to the cavity 5 of the corresponding sleeve 2. This continuous airflow acts on a specially designed rotating ring 6 within the cavity 5 of the sleeve 2, using the kinetic energy of the airflow to drive the rotating ring 6 to rotate smoothly around the cable axis. Several nozzles 7 are evenly installed on this rotating ring 6. As the rotating ring 6 rotates, these nozzles 7 are also driven to rotate synchronously. During this process, the nozzles 7 continuously spray high-speed, concentrated airflow jets. Because the nozzles themselves are rotating, the airflow they spray can dynamically and comprehensively wash the outer surface of the cable passing beneath them. This rotating spray mode greatly improves the uniformity and efficiency of the washing, thereby effectively stripping and removing moisture or water stains adhering to the cable surface, achieving the purpose of drying and cleaning.

[0030] Example 2: In Example 1, the air pressure required to drive the rotating ring 6 is too high. This high pressure requirement directly results in an excessively strong and difficult-to-control blowing airflow from the associated nozzle 7 onto the cable surface. The excessive airflow impact force can easily damage the cable's outer sheath or insulation layer. Based on Example 1, optimizations are made, referencing... Figure 1-6 Both rotating rings 6 are equipped with rotating mechanisms, each including a rotating shaft 8 placed on one side of the sleeve 2. The rotating shaft 8 is connected to the sleeve 2 via a sealed bearing, with one end extending into the cavity 5. A friction ring 9 is provided on the outer side of the rotating ring 6, and a friction wheel 10 is connected to one end of the rotating shaft 8. The friction ring 9 and the friction wheel 10 cooperate with each other. A drive assembly is provided in the middle of the top of the support frame 1. The output end of the drive assembly is connected to one end of the two rotating shafts 8. Both the friction ring 9 and the friction wheel 10 are provided with a nitriding layer on their outer sides. The nitriding layer has excellent anti-galling properties and can effectively prevent adhesive wear (adhesion) between the two metal surfaces under high pressure, high speed or poor lubrication conditions, ensuring smooth and reliable transmission.

[0031] The drive assembly includes a fixed base 11 installed in the middle of the support frame 1, a long shaft 12 connected to one end of one of the rotating shafts 8, a motor 13 installed at the bottom of the fixed base 11, a first bevel gear 14 provided on the output end of the motor 13, and a second bevel gear 15 provided on the outside of the long shaft 12. The first bevel gear 14 and the second bevel gear 15 mesh with each other, and the transmission ratio between the first bevel gear 14 and the second bevel gear 15 is 5:1.

[0032] Working principle: The motor 13 is started, and its output shaft drives the first bevel gear 14 to rotate, which in turn meshes with and drives the second bevel gear 15 into a slow-moving state. The second bevel gear 15 drives the long shaft 12 to rotate, which in turn drives two rotating shafts 8. Each rotating shaft 8 drives a friction wheel 10 to rotate, and the power is transmitted to the friction ring 9 in contact with it via a friction pair. Each friction ring 9 drives a rotating ring 6 to rotate. This multi-stage reduction structure using friction transmission, with its controllable sliding characteristics between the friction wheel 10 and the friction ring 9, allows for precise adjustment and buffering of the rotational speed of the rotating ring 6 and the several nozzles 7 mounted on it. Compared to the direct drive method in Embodiment 1, this design significantly reduces the airflow intensity generated by the nozzles 7, thereby greatly mitigating the potential impact damage risk to the cable surface from high-speed airflow.

[0033] Example 3: An optimization based on Examples 1-2, with reference to... Figure 1-6 A pipe 17 is connected to one side of the top of the fan assembly 3. A heating coil assembly 18 is installed inside the pipe 17, and one end of a connecting pipe 4 is connected to one end of the pipe 17.

[0034] Working principle: After the fan assembly 3 is started, the airflow generated by it is transported to the heating coil assembly 18 through the pipe 17 for full heating, forming hot air at the preset temperature; the hot air then enters the target sleeve 2 through the corresponding connecting pipe 4, and is finally sprayed out at high speed by several nozzles 7 distributed on the sleeve. This directional jet of hot air acts on the cable surface, and the high-temperature airflow accelerates the evaporation and stripping of moisture, thereby effectively removing water mist from the cable surface and improving the water removal effect on the cable surface.

[0035] Example 4: An optimization based on Examples 1-3, with reference to... Figure 1-6 A sponge wheel assembly 16 is provided on the top of the fixing base 11. The top of the sponge wheel assembly 16 presses against the bottom of the cable to wipe away water stains on the bottom of the cable, so that the hot air sprayed from the nozzles 7 in embodiment 4 can more effectively remove water mist from the surface of the cable.

[0036] Example 5: An optimization based on Examples 1-2, with reference to... Figure 1-6 The nozzles 7 on the rotating ring 6 are all arranged at an angle, with their spray axes forming a 30° angle with the horizontal plane. On the one hand, the tilt angle effectively prevents water stains accumulated at the bottom of the cable from flowing back or splashing under gravity or airflow disturbance, thus significantly reducing the risk of water stains being sucked into the nozzles 7 and ensuring the smooth flow of air through the nozzles 7 and the reliability of long-term operation. On the other hand, the tilted arrangement allows the high-speed airflow ejected from the nozzles to act tangentially on the cable surface. This directional blowing greatly enhances the efficiency of airflow in removing surface water stains, significantly accelerates the water removal process on the entire cable surface, and ultimately improves the water removal efficiency of the production line.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
