Description

Technical Field

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

[0002] Cable drying is a critical step in the cable manufacturing process. During production, moisture often adheres to the surfaces of the insulation and sheath layers after extrusion molding. If this moisture is not effectively removed, it can severely negatively impact the cable's electrical performance, such as reducing insulation resistance, increasing dielectric loss, and consequently affecting transmission performance and service life. Furthermore, moisture can trigger partial discharge during operation, accelerate insulation aging, and even lead to insulation breakdown, causing serious safety accidents.

[0003] Many existing cable drying devices lack effective guiding and limiting structures during cable transport. When cables enter the drying device, they are prone to shaking and deviation due to uneven tension or changes in internal friction. For example, in some simple hot air circulating drying chambers, cables are transported only by simple rollers without dedicated limiting devices. This can cause cables to deviate from their intended path during transport, scraping against the inner wall of the drying chamber or other components, damaging the cable surface and potentially affecting its electrical performance. Furthermore, traditional cable drying devices commonly suffer from uneven drying. Taking hot air circulating drying devices as an example, the flow of hot air is easily affected by the internal structure of the drying chamber, resulting in uneven distribution of hot air. Cable sections near the hot air outlet receive direct hot air and dry faster, while sections far from the outlet or in hot air dead zones dry more slowly. This uneven drying causes differences in moisture content across different parts of the cable, affecting its overall performance and quality. Therefore, a cable drying device for cable production needs to be designed. Utility Model Content

Example

[0019] Based on the existing problems of cable conveying stability, drying uniformity, and poor equipment adaptability, this utility model provides a preferred embodiment of a cable drying device for cable production, for example... Figure 1-4The diagram shows a cable drying device for cable production, comprising a supporting base plate 1, a supporting steel frame 11 fixedly mounted on the top of the supporting base plate 1, a cable wheel mounting frame 2 fixedly mounted on the top of the supporting base plate 1, the cable wheel mounting frame 2 being disposed on one side of the supporting steel frame 11, a cable rotating cylinder 3 being disposed between the cable wheel mounting frames 2, a drying chamber 4 being disposed on the other side of the supporting steel frame 11, an inlet 41 being opened on one side of the outer wall of the drying chamber 4, an outlet 42 being opened on the other side of the outer wall of the drying chamber 4, a central control adjustment box 5 being fixedly mounted on the front of the drying chamber 4; and a cable drying assembly 6, which is disposed inside the drying chamber 4 and inside the supporting steel frame 11; the cable drying assembly 6 includes: a guiding and conveying part 61, which is disposed inside the supporting steel frame 11 and inside the drying chamber 4; and a drying part 62, which is disposed inside and above the drying chamber 4, and the drying part 62 is disposed above the guiding and conveying part 61.

[0020] The guiding and conveying part 61 includes: an adjusting slide hole 611, which is opened on the inner wall of the supporting steel frame 11, and there are two sets of them, arranged symmetrically; a supporting arc block 612 is provided on one side of the adjusting slide hole 611, and the supporting arc block 612 is fixedly installed on the outer wall of the supporting steel frame 11. A small motor 613 is fixedly installed at the bottom of the supporting arc block 612. The output end of the small motor 613 is provided with a small double-threaded rod 614 through a coupling, and the small double-threaded rod 614 extends into the interior of the adjusting slide hole 611.

[0021] A limiting plate 615 is movably sleeved on the outer wall of the small bidirectional threaded rod 614, and the limiting plate 615 is slidably connected to the adjusting sliding hole 611. An arc-shaped guide groove 616 is opened on the inner side wall of the limiting plate 615, and a protective arc-shaped pad 617 is fixedly installed on the inner wall of the arc-shaped guide groove 616.

[0022] A conveyor frame 618 is provided on one side of the protective arc-shaped pad 617, and the conveyor frame 618 is fixedly installed on the inner wall of the drying oven 4, located between the inlet 41 and the outlet 42. The conveyor frame 618 is equipped with a conveyor roller 619 inside.

[0023] Furthermore, in this embodiment, a small motor 613 drives a small bidirectional threaded rod 614 to rotate, causing the limiting plate 615 to slide along the adjusting slide hole 611. The arc-shaped guide groove 616 can adaptively adjust the spacing according to the cable diameter, without the need to replace the guide components, thus meeting the flexible requirements of "multiple specifications and small batches" in cable production. The supporting arc-shaped block 612 provides stable support for the small motor 613, ensuring that the small bidirectional threaded rod 614 rotates without shaking. The radial limiting deviation of the limiting plate 615 on the cable is reduced, avoiding friction between the cable and the edges of the inlet 41 and outlet 42 of the drying oven 4. The protective arc-shaped pad 617 on the inner wall of the arc-shaped guide groove 616 is made of wear-resistant rubber, increasing the friction with the cable, buffering the impact during the guiding process, and preventing scratches on the cable surface. Example

[0024] Based on Embodiment 1, a preferred embodiment of the cable drying device for cable production provided by this utility model is, for example... Figure 1-4 As shown: The drying section 62 includes: a motor 621, which is fixedly mounted on the outer wall of the drying chamber 4 via a support base; a protective cover 628, which is fixedly mounted on the top of the drying chamber 4, and the outer wall of the protective cover 628 is provided with air vents at equal intervals; the output end of the motor 621 is provided with a large bidirectional threaded rod 622 via a coupling, and the large bidirectional threaded rod 622 extends into the interior of the drying chamber 4. A connecting block is movably sleeved on the outer wall of the large bidirectional threaded rod 622, and a first lifting arm 623 is fixedly mounted on the outer wall of the connecting block via a fixing pin. The first lifting arm 623 is symmetrically provided with a second lifting arm 624, and the second lifting arm 624 is sleeved on the outer wall of the large bidirectional threaded rod 622 via a movable block.

[0025] The bottom of the first lifting arm 623 and the second lifting arm 624 are provided with mounting connecting seats 625 by fixing pins. The bottom of the mounting connecting seat 625 is fixedly installed with a wind collector 626. The two ends of the wind collector 626 are provided with lifting guide plates 627, and the inner side of the lifting guide plate 627 is provided with a sliding groove. The two ends of the wind collector 626 are slidably connected to the sliding groove.

[0026] Inside the protective cover 628, fans 629 are evenly spaced. The connection port of the fans 629 is connected to a main air supply pipe, and the bottom of the main air supply pipe is evenly spaced to a metal telescopic pipe 6210. The metal telescopic pipe 6210 extends to the top of the air collecting cover 626, and the bottom end of the metal telescopic pipe 6210 is connected to an air supply pipe 6211, which extends into the interior of the air collecting cover 626. The interior of the air collecting cover 626 has a drying air chamber 6212, and two sets of air guide plates 6213 are fixedly installed inside the drying air chamber 6212, arranged symmetrically.

[0027] Heating plates 6214 are provided on both sides of the air collecting hood 626, and the heating plates 6214 are fixedly installed on the inner walls of both sides of the drying oven 4. Heating resistance wires 6215 are evenly and uniformly fixedly installed inside the heating plates 6214.

[0028] Furthermore, in this embodiment, a motor 621 drives the first lifting arm 623 and the second lifting arm 624 in conjunction with a large bidirectional threaded rod 622, causing the air collecting hood 626 to slide along the lifting guide plate 627. This achieves precise height adjustment within the standard range from the cable surface. In conjunction with the air guide plate 6213, the hot air is dispersed into an annular airflow and evenly blown onto the circumferential surface of the cable, avoiding the "localized dry dead corners" caused by traditional unidirectional airflow. At the same time, the wind speed of the fan 629 can be adjusted as needed to avoid energy waste. In addition, the heating plate 6214 and the heating resistance wire 6215 are installed separately, so there is no need to replace the whole thing when a single resistance wire is damaged, reducing maintenance costs.

[0029] During use, the operator first completes a basic status check of the equipment: confirm that the support base plate 1 is placed stably, the support steel frame 11 is firmly connected to the cable turner mounting frame 2, and there is no looseness or deformation; check that the cable turner 3 rotates smoothly when winding the cable to be dried, without any jamming; verify that there is no debris blocking the inlet 41 and outlet 42 of the drying chamber 4, and that the display panel of the main control adjustment box 5 is clear and the buttons are responsive; confirm that the small motor 613 and conveyor roller 619 of the guide conveyor part 61, as well as the motor 621, fan 629, and heating plate 6214 of the drying part 62 are powered normally, and that the motors are connected to power and the heating circuit is not short-circuited. Based on the specifications and drying requirements of the cable to be dried, the core parameters are set through the main control adjustment box 5: the speed of the small motor 613 controls the spacing of the limit plates, the conveying roller 619 adjusts the conveying speed to match the cable production cycle, the heating resistance wire 6215 adjusts the heating temperature to avoid high temperature damage to the cable insulation layer, the fan 629 adjusts the wind speed according to the cable diameter, and the air collection hood 626 is 5-15mm above the cable surface to ensure the effective action of hot air and complete the equipment initialization.

[0030] Cable installation and no-load commissioning The cable to be dried is led out from the cable rotating drum 3 and passed sequentially through the arc-shaped guide groove 616 in the supporting steel frame 11, the inlet 41 of the drying chamber 4, and the conveying roller 619 in the conveying frame 618, finally exiting from the outlet 42, ensuring that the cable is in a horizontal state without twisting or excessive stretching; start the no-load debugging mode: control the small motor 613 to drive the limit plate 615 to slide along the adjustment sliding hole 611 to verify the fit between the arc-shaped guide groove 616 and the cable; start the motor 621 and observe whether the first lifting arm 623 and the second lifting arm 624 drive the air collecting hood 626 to slide smoothly along the lifting guide plate 627; start the heating plate 6214 and the fan 629 to check whether the temperature in the drying chamber 4 reaches the set value and whether the hot air is blown out evenly from the air collecting hood 626. After all components are operating normally, the formal drying process begins. Furthermore, this embodiment includes a small starting motor 613, whose output end drives a small bidirectional threaded rod 614 to rotate within an adjusting slide hole 611 via a coupling. Two sets of limiting plates 615, fitted onto the outer wall of the threaded rod, slide in opposite directions along the adjusting slide hole 611 until the arc-shaped guide groove 616 on the inner sidewall of the limiting plate 615 fits against the cable surface. The protective arc-shaped pad 617 on the inner wall of the arc-shaped guide groove 616 is made of wear-resistant rubber, which not only prevents scratches on the cable surface but also limits the radial deviation of the cable during transportation, ensuring that the cable is accurately aligned with the inlet 41 and avoiding wear of the insulation layer caused by friction with the edge of the box opening. The supporting arc-shaped block 612 provides stable support for the small motor 613, ensuring that the small bidirectional threaded rod 614 rotates without shaking. The adjustment accuracy of the limiting plate 615 can adapt to cables of different diameters without the need to replace the guide assembly. The conveyor rollers 619 inside the conveyor frame 618 are activated. The rollers drive the cable to move at a uniform speed through friction with the cable surface. This can be adjusted in real time via the central control adjustment box 5, ensuring that the cable passes through the drying box 4 continuously and smoothly. The conveyor rollers 619 are made of elastic rubber, which increases friction with the cable to prevent slippage and can adapt to the compression requirements of cables of different diameters, ensuring stable conveying speed and providing a foundation for subsequent uniform drying.

[0031] Based on the cable diameter and drying requirements, the motor 621 is started via the main control adjustment box 5. Its output end drives the large bidirectional threaded rod 622 to rotate, which drives the connecting block of the first lifting arm 623 and the second lifting arm 624 to move towards each other, reducing the angle between the two sets of lifting arms. This pushes the mounting connecting seat 625 to move the air collecting hood 626 downward along the sliding groove of the lifting guide plate 627 until the bottom of the air collecting hood 626 reaches the set value with respect to the cable surface. Conversely, if it is necessary to increase the distance, the motor 621 can be controlled to rotate in the opposite direction, which increases the angle between the lifting arms and raises the air collecting hood. Simultaneously, the fan 629 inside the protective cover 628 and the heating plates 6214 on both sides of the drying chamber 4 are activated: the heating resistance wire 6215 is energized and heats up, raising the air temperature inside the drying chamber 4 to 60-120℃; the fan 629 draws in external air, which is distributed through the main air supply pipe to the metal telescopic pipe 6210, which moves synchronously with the rise and fall of the air collection hood to ensure continuous air supply, and then sent into the drying air chamber 6212 of the air collection hood 626 through the air supply pipe 6211; the two sets of symmetrical guide air plates 6213 in the drying air chamber guide the hot air to be evenly dispersed, so that the hot air is blown evenly from the bottom of the air collection hood to the cable surface at a wind speed of 3-8m / s, forming a ring-shaped hot air coverage area, which quickly removes the moisture from the cable surface. Adjustable height and airflow speed of the air collection hood allow for precise application of hot air to cables of different diameters. For example, higher airflow speed and shorter distance are used for thinner cables, while lower airflow speed and longer distance are used for thicker cables. This prevents localized overheating or incomplete drying, improving drying uniformity and ensuring the surface moisture content of the cables remains consistently within a suitable range. The central control box 5 monitors the temperature inside the drying chamber 4 in real time using a built-in temperature sensor. When the temperature is below the set value, the power of the heating resistance wire 6215 is automatically increased; when the temperature is above the set value, the power is reduced or heating is paused to ensure temperature fluctuations within the chamber remain within acceptable limits. Ventilation holes on the outer wall of the protective cover 628 allow for timely removal of humid air and replenishment of fresh air, preventing excessive humidity within the drying chamber and further improving drying efficiency. Finally, the dried cables are continuously output from the outlet 42 of the drying chamber 4 and can directly enter subsequent production processes such as printing and winding. Operators regularly take samples and test the surface moisture content of the cables using a moisture analyzer to ensure that they meet production standards. If the drying is found to be substandard, the conveying speed can be appropriately reduced, the heating temperature increased, or the fan speed increased through the main control adjustment box 5 until the requirements are met. After a batch of cables is dried, the heating plate 6214 and the fan 629 are turned off. After the temperature inside the drying chamber 4 drops to room temperature, the dust and debris remaining in the chamber can be removed by blowing with compressed air. Check whether there is any debris blocking the drying air chamber 6212 and the air guide plate 6213 of the air collector 626 to ensure that the hot air is uniform for the next use. Control the motor 621 to drive the air collector 626 to rise to the initial position, control the small motor 613 to drive the limit plate 615 to reset to the maximum spacing, turn off the main control adjustment box 5, and tidy up after the operation is completed.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
