Description

Technical Field

[0001] This utility model relates to the field of coating device technology, and in particular to a wide temperature range insulation coating device for network cables. Background Technology

[0002] With the rapid development of information technology, the network plays a vital role in people's lives and work. As the physical carrier of data transmission, the performance of network cables directly affects the stability and transmission efficiency of the network. In order to ensure reliable signal transmission and protect the safety of personnel and equipment, network cables need to have good insulation performance. The insulation layer can not only prevent signal interference between cables, but also prevent leakage. Therefore, high requirements are placed on the quality and performance of the insulation layer.

[0003] The network cable insulation coating device mainly consists of a cable feeding mechanism, a coating supply component, a coating mold, a drying and curing device, and a control component. The cable feeding mechanism conveys the cable at a uniform speed, and the coating supply component precisely controls the flow and pressure of the coating, which is then transported through a pipeline to the coating mold. The coating mold is designed according to the cable specifications. When the cable passes through it, the annular gaps in the mold allow the coating to be evenly applied to the surface of the cable. Subsequently, the cable enters the drying and curing device, where the coating is quickly dried and cured into an insulation layer by means of hot air or infrared heating. The control component coordinates the operation of each component and monitors parameters such as coating thickness and temperature in real time to ensure a stable and efficient coating process, achieving uniform and precise coating of the insulation layer.

[0004] Current insulation coating devices lack a limiting and guiding structure that can be quickly adjusted according to different cable diameters. This results in low coating efficiency and quality problems such as uneven coating and inconsistent insulation thickness when facing the production needs of various cable specifications, increasing production costs and defect rates. To address these issues, a wide temperature range insulation coating device for network cables is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a wide temperature range insulation coating device for network cables, which aims to improve the problem of the lack of a limiting and guiding structure in the prior art that can be quickly adjusted according to different cable diameters.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wide-temperature-range insulation coating device for network cables includes a fixed plate, a plurality of support columns fixedly connected to the bottom end of the fixed plate, a pretreatment component fixedly connected to the top end of the fixed plate, a coating mold head fixedly connected to the top end of the fixed plate, a limiting mechanism provided inside the fixed plate, a cleaning mechanism provided at the front end of the limiting mechanism, and a cable provided outside the limiting mechanism.

[0008] The limiting mechanism includes a push column, which is slidably connected to the outside of the fixed plate. Guide blocks are fixedly connected to both ends of the push column. A rotating wheel is slidably connected to the top of the guide block. A transmission rod is fixedly connected to the top of the rotating wheel. A rotating column is fixedly connected to the top of the transmission rod. A rotating rod is fixedly connected to the top of the rotating column. A limiting wheel is rotatably connected to the top of the push column and the inside of the rotating rod. A drive assembly is provided on the outside of the push column.

[0009] The above technical solution constructs a complete and functionally coordinated auxiliary structure for coating network cable insulation. Within the limiting mechanism, various components cooperate, utilizing the sliding of the push column to achieve a series of transmissions. As the push column slides, it moves the guide block, which in turn pushes the rotating wheel to roll. The rotating wheel, through a transmission rod, rotating column, and rotating rod, converts linear motion into rotation, precisely adjusting the position of the limiting wheel. This allows the limiting wheel to closely conform to cables of different diameters, effectively limiting and guiding them. This ensures that the cable maintains a stable position and trajectory when entering the pretreatment components and coating die, significantly improving the stability of the cable position during the coating process and laying a solid foundation for subsequent uniform and high-quality insulation coating.

[0010] As a further description of the above technical solution:

[0011] The rotating column is rotatably connected to the inside of the fixed plate, the outside of the limiting wheel is in contact with the outside of the cable, and a curing component is fixedly connected to the top of the fixed plate.

[0012] Through the above technical solution, the rotating column can rotate stably within the fixed plate, and the limiting wheel is in direct contact with the cable, so that the limiting mechanism can effectively limit and guide the cable, ensuring that the cable maintains a stable position during the coating process, avoiding deviation, and thus improving the coating quality.

[0013] As a further description of the above technical solution:

[0014] The drive assembly includes two guide blocks, the two guide blocks are fixedly connected to the inside of the fixed plate, the push column is slidably connected to the adjacent side of the two guide blocks, and a cylinder is fixedly connected to the adjacent side of the two support columns.

[0015] Through the above technical solution: guide block 2 provides precise guidance for the sliding of the push column, ensuring the accuracy of the push column's movement; the cylinder, as a power source, provides driving force for the movement of the push column, enabling the push column to slide stably within the fixed plate along a predetermined trajectory, providing a power basis for adjusting the position of the limit wheel.

[0016] As a further description of the above technical solution:

[0017] The driving end of the cylinder is fixedly connected to the bottom end of the push column, and the bottom end of the first guide block is in contact with the top end of the second guide block.

[0018] Through the above technical solution: when the cylinder drive end pushes the push column to move, the bottom end of guide block one contacts the top end of guide block two, which not only helps to support the push column, but also further enhances the stability of the push column movement, ensuring the stable operation of the entire limiting mechanism and accurately realizing the limiting and guiding functions of the cable.

[0019] As a further description of the above technical solution:

[0020] The cleaning mechanism includes a fixed box, the rear end of which is fixedly connected to the front end of the push column. A transmission gear is rotatably connected inside the fixed box. A motor is fixedly connected to the front end of the fixed box. An outer ring is fixedly connected to the top end of the fixed box. An inner ring is slidably connected inside the outer ring. Multiple cleaning brushes are fixedly connected inside the inner ring. The transmission gear is meshed with the inner ring. A collection component is provided inside the fixed plate.

[0021] The above technical solution involves a cleaning mechanism that moves with the push column, and a motor-driven transmission gear that moves the inner ring and cleaning brush to clean the cable surface, removing impurities and debris. This prevents these impurities from affecting the bonding between the insulation material and the cable, ensuring the coating effect.

[0022] As a further description of the above technical solution:

[0023] The drive end of the motor is fixedly connected inside the transmission gear, and the outside of the cleaning brush is in contact with the outside of the cable;

[0024] Through the above technical solution, the motor power is effectively transmitted to the transmission gear, which drives the cleaning brush to rotate, enabling the cleaning brush to continuously scrape and clean the cable surface, efficiently removing impurities from the cable surface and creating favorable conditions for the subsequent coating process.

[0025] As a further description of the above technical solution:

[0026] The collection assembly includes a collection plate, the outside of which is fixedly connected to the inside of a fixed plate, and a collection box is fixedly connected to the inside of the fixed plate;

[0027] The above technical solution consists of a collection plate and a collection box. The collection plate can guide the impurities scraped off by the cleaning brush to the collection box, which facilitates centralized storage of impurities, makes it convenient to clean regularly, keeps the inside of the device clean, and avoids impurities interfering with the coating process.

[0028] As a further description of the above technical solution:

[0029] The outer side of the guide block is slidably connected to the inside of the fixed plate, and the bottom end of the outer ring is fixedly connected to the top end of the push column.

[0030] Through the above technical solution: the guide block slides more stably in the fixed plate, and the outer ring is firmly connected to the push column, so that the cleaning mechanism can reliably move synchronously with the push column, ensuring that the cleaning brush can always accurately clean the cable and ensuring that the cleaning work is carried out continuously and stably.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the operator starts the cylinder, which pushes the push column to slide, causing the rotating column to rotate, so that the rotating rod adjusts the position of the limit wheel. The limit wheels at different positions cooperate with each other to accurately adapt to cables of different diameters, allowing all kinds of cables to move stably in the horizontal direction. This process ensures that the cable is stable in the pretreatment, coating and curing stages, thereby ensuring uniform coating of insulation material, improving coating quality and meeting the production needs of cables of different specifications.

[0033] 2. In this utility model, the cleaning mechanism and the limiting mechanism work together and move with the push column. When the cable passes through the outer ring under the guidance of the limiting wheel, the motor is started. The motor drives the transmission gear to rotate, causing the inner ring to slide inside the outer ring, so that the cleaning brush scrapes the surface of the cable. The cleaning brush scrapes off the impurities and debris on the surface of the cable, which are guided by the collection plate and fall into the collection box. This cleaning process effectively removes impurities, prevents them from affecting the bonding between the insulation material and the cable, ensures the smooth progress of subsequent coating operations, and improves the quality of the final product.

[0040] 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.

[0041] Reference Figures 1 to 3This utility model provides an embodiment of a wide-temperature-range insulation coating device for network cables, comprising a fixed plate 1. Multiple support columns 2 are fixedly connected to the bottom of the fixed plate 1, evenly distributed to ensure smooth coating operations. A pretreatment component 3 is fixedly connected to the top of the fixed plate 1. The pretreatment component 3 employs plasma activation technology to activate the surface of the cable 8 before it enters the coating process, increasing the surface activity of the cable 8 and improving the adhesion between the subsequent insulation material and the cable 8. This enhances the bonding strength between the insulation layer and the cable 8, laying the foundation for a high-quality coating effect. A coating die 4 is fixedly connected to the top of the fixed plate 1. The coating die 4 consists of adjustable-gap inner and outer dies. By adjusting the gap between the inner and outer dies, the thickness of the insulation material coated on the cable 8 can be precisely controlled, ensuring that the insulation layer thickness meets the production requirements of different cable specifications and guaranteeing the cable's performance. The electrical and physical properties are stable. A curing component 5 is fixedly connected to the top of the fixing plate 1. The curing component 5 achieves gradient heat treatment through an infrared tunnel, which can provide different temperature conditions according to different stages of the insulation material curing process, so that the insulation material can be fully cross-linked and cured to form a stable insulation layer structure, thereby improving the performance of the insulation layer in a wide temperature range. A limiting mechanism 6 is set inside the fixing plate 1. The limiting mechanism 6 is used to limit and guide the cable 8 to ensure that the cable 8 maintains a stable position throughout the coating process and avoids its deviation, thereby ensuring the coating quality. A cleaning mechanism 7 is set at the front end of the limiting mechanism 6. The cleaning mechanism 7 cleans the surface of the cable 8 before it enters the pretreatment component 3, removing impurities and debris to prevent these impurities from affecting the bonding between the insulation material and the cable 8 and ensuring the coating effect. The cable 8 is set outside the limiting mechanism 6. The cable 8 is the processing object of the entire coating operation.

[0042] Specifically, during the operation of the wide-temperature-range insulation coating device for network cables, the fixing plate 1 plays a crucial supporting and connecting role. The support columns 2 at the bottom of the fixing plate 1 are evenly distributed, providing stable support and ensuring the smooth operation of the coating process. The pretreatment component 3 at the top uses plasma activation technology to activate the surface of the cable 8 before it enters the coating process, enhancing surface activity and improving the adhesion between the insulation material and the cable 8, thus laying the foundation for high-quality coating. The coating die 4 precisely controls the coating thickness of the insulation material through adjustable gap inner and outer dies, ensuring the stability of the electrical and physical properties of the cable. The curing component 5 utilizes infrared tunneling to achieve gradient heat treatment, providing different temperatures according to the curing stage of the insulation material, allowing the insulation material to fully cure and improving the performance of the insulation layer in a wide temperature range. The limiting mechanism 6 is used to limit and guide the cable 8. The cleaning mechanism 7 cleans the surface of the cable 8 before it enters the pretreatment component 3.

[0043] The limiting mechanism 6 includes a push column 61, which is externally slidably connected to the inside of the fixed plate 1. The sliding of the push column 61 inside the fixed plate 1 is the key movement method for adjusting the position of the limiting wheel 67. Guide blocks 62 are fixedly connected to both ends of the push column 61. The guide blocks 62 are key parts for connecting and transmitting power between the push column 61 and subsequent components, and play a role in transmitting power and providing support. A rotating wheel 63 is slidably connected to the top of the guide block 62. A transmission rod 64 is fixedly connected to the top of the rotating wheel 63. A rotating column 65 is fixedly connected to the top of the transmission rod 64. A rotating rod 66 is fixedly connected to the top of the rotating column 65. The sliding of the rotating wheel 63 at the top of the guide block 62 rotates the linear motion of the push column 61. The rotation of the rotating wheel 63 is further transmitted to the rotating column 65 by the transmission rod 64, ensuring effective power transmission. The rotating column 65 is an important component in the limiting mechanism 6 for realizing angle conversion and power transmission. The rotation of the rotating column 65 drives the rotating rod 66 to rotate. The rotating rod 66 converts the rotation of the rotating column 65 into position adjustment of the limiting wheel 67, thereby realizing the limiting and guiding function of the cable 8. The top of the push column 61 and the inside of the rotating rod 66 are rotatably connected to the limiting wheel 67. The limiting wheel 67 is in direct contact with the cable 8. Through its own rotation and position adjustment, it limits and guides the cable 8, ensuring that the cable 8 moves stably on a horizontal line. The push column 61 is equipped with a drive assembly 68 on its outside.

[0044] Specifically, the push column 61 of the limiting mechanism 6 slides within the fixed plate 1. This sliding is crucial. The guide blocks 62 at both ends of the push column 61 are connected to and transmit power, driving the rotating wheel 63 to roll. The rotating wheel 63 sequentially passes through the transmission rod 64, the rotating column 65, and the rotating rod 66, converting linear motion into rotation, ultimately achieving the position adjustment of the limiting wheel 67. The limiting wheel 67 directly contacts the cable 8, and through its own rotation and position change, it limits and guides the cable 8, ensuring that the cable 8 moves stably in the horizontal direction, providing a stable cable position basis for subsequent processing.

[0045] The drive assembly 68 provides the power source for the movement of the push column 61. The external rotatable connection of the rotating column 65 is to the inside of the fixed plate 1, ensuring that the rotating column 65 can rotate stably within the fixed plate 1, thus guaranteeing the normal operation of the entire limiting mechanism 6. The external of the limiting wheel 67 contacts the external of the cable 8, directly acting on the cable 8 to limit and guide it. The drive assembly 68 includes two guide blocks 681, which are externally fixedly connected to the inside of the fixed plate 1. The guide blocks 681 provide precise guidance for the sliding of the push column 61, ensuring that the push column 61 can only slide along a specific direction, guaranteeing the accuracy of the push column 61's movement. The external of the push column 61 is slidably connected to the adjacent side of the two guide blocks 681. To ensure the stable sliding of the push column 61 under the constraint of the guide block 681, a cylinder 682 is fixedly connected to the adjacent side of the two support columns 2. As the core power element of the drive assembly 68, the cylinder 682 can generate a strong thrust. The drive end of the cylinder 682 is fixedly connected to the bottom end of the push column 61. When the cylinder 682 is started, its drive end extends or retracts, directly pushing the push column 61 to move. The bottom end of the guide block 62 contacts the top end of the guide block 681. During the movement of the push column 61, the bottom end of the guide block 62 slides along the top end of the guide block 681, playing an auxiliary support and guiding role. The outside of the guide block 62 is slidably connected to the inside of the fixed plate 1, further ensuring the stability of the guide block 62 during the movement.

[0046] Specifically, the drive assembly 68 provides power to the push column 61 of the limiting mechanism 6. Guide block 2 681 is fixed within the fixed plate 1, providing precise guidance for the sliding of the push column 61, ensuring stable and accurate movement. Cylinder 682 is installed between the two support columns 2, serving as the core power component. Its drive end is connected to the bottom of the push column 61. Activating cylinder 682 causes its drive end to extend and retract, pushing the push column 61. During the movement of the push column 61, the bottom end of guide block 1 62 slides along the top end of guide block 2 681, providing auxiliary support and guidance, ensuring the stable movement of guide block 1 62 and the entire limiting mechanism 6.

[0047] Reference Figure 1 , Figure 2 and Figure 4The cleaning mechanism 7 includes a fixed box 71, the rear end of which is fixedly connected to the front end of the push column 61, allowing the cleaning mechanism 7 to move with the push column 61 and maintain a relatively stable position relative to the cable 8, facilitating cleaning of the cable 8. A transmission gear 72 is rotatably connected inside the fixed box 71, playing a crucial role in transmitting power in the cleaning mechanism 7. A motor 73 is fixedly connected to the front end of the fixed box 71, serving as the power source for the cleaning mechanism 7 and providing power for the rotation of the transmission gear 72. An outer ring 74 is fixedly connected to the top of the fixed box 71, and an inner ring 75 is slidably connected inside the outer ring 74. Multiple cleaning brushes 76 are fixedly connected inside the inner ring 75. The outer ring 74 provides a track for the sliding of the inner ring 75 and also protects the internal structure. The inner ring 75 slides to allow the cleaning brush 76 to clean different positions on the cable 8. The cleaning brush 76 directly contacts the cable 8 and scrapes the outside of the cable 8 through its own rotation to remove impurities and debris from the surface of the cable 8. The transmission gear 72 is meshed with the inner ring 75, so that the power of the motor 73 can be transmitted to the inner ring 75 through the transmission gear 72, causing the inner ring 75 to rotate. The fixed plate 1 is equipped with a collection component 77, which is used to collect the impurities and debris scraped off the surface of the cable 8 by the cleaning brush 76. The drive end of the motor 73 is fixedly connected to the inside of the transmission gear 72 to ensure that the power of the motor 73 can be effectively transmitted to the transmission gear 72. The outside of the cleaning brush 76 is in contact with the outside of the cable 8, directly performing the task of cleaning impurities on the surface of the cable 8.

[0048] Specifically, the rear end of the fixing box 71 of the cleaning mechanism 7 is connected to the front end of the push column 61 and moves with the push column 61. The motor 73 is fixed to the front end of the fixing box 71 and provides power to the cleaning mechanism 7. The motor 73 drives the transmission gear 72 to rotate. The transmission gear 72 meshes with the inner ring 75 and drives the inner ring 75 to slide inside the outer ring 74. The cleaning brush 76 on the inner ring 75 contacts the cable 8 and scrapes the surface of the cable 8 when rotating to remove impurities and debris. The collection component 77 in the fixing plate 1 is responsible for collecting these impurities to ensure the surface of the cable 8 is clean and improve the coating effect.

[0049] The collection component 77 includes a collection plate 771, which is externally fixedly connected to the inside of the fixed plate 1. The collection plate 771 is inclined and can guide the impurities and debris scraped off by the cleaning brush 76 into the collection box 772. The collection box 772 is fixedly connected to the inside of the fixed plate 1. The collection box 772 is used to centrally store impurities and debris for easy periodic cleaning. The bottom end of the outer ring 74 is fixedly connected to the top end of the push column 61 to ensure a stable connection between the outer ring 74 and the push column 61, so that the cleaning mechanism 7 can move together with the push column 61.

[0050] Specifically, the collection plate 771 of the collection component 77 is fixed inside the fixed plate 1, which can guide the impurities and debris scraped off by the cleaning brush 76 to the collection box 772. The collection box 772 is fixed inside the fixed plate 1 for centralized storage of impurities, which is convenient for regular cleaning. The bottom end of the outer ring 74 is fixed to the top end of the push column 61 to ensure that the cleaning mechanism 7 and the push column 61 are firmly connected and can move synchronously to effectively complete the cleaning work of the cable 8.

[0051] Working principle: When the processing personnel need to coat the cable 8 with an insulation layer, the cylinder 682 is activated. The cylinder 682 drives the push column 61 to slide inside the guide block 681, thereby causing the guide block 62 to push the rotating wheel 63 to roll, causing the rotating column 65 to rotate, and causing the rotating rod 66 to drive the limiting wheel 67 to adjust its position. By cooperating with the limiting wheel 67 at the top of the push column 61 and the limiting wheels 67 on both sides, cables 8 of different diameters can be limited and guided, so that cables 8 of different sizes can move on a horizontal line. This ensures the stability of the position of the cable 8 during subsequent processing by the pretreatment component 3, coating die head 4 and curing component 5, and ensures the coating quality. The coating die head 4 consists of inner and outer molds with adjustable gaps. The pretreatment component 3 adopts plasma activation technology, and the curing component 5 achieves gradient heat treatment through infrared tunneling.

[0052] The cleaning mechanism 7 moves along with the push column 61, allowing the cable 8 to pass through the inner ring 74 when limited and guided by the limiting mechanism 6. Simultaneously, the motor 73 is activated, driving the transmission gear 72 to rotate. This causes the inner ring 75 to slide inside the outer ring 74, allowing the cleaning brush 76 to scrape the outside of the cable 8. Impurities and debris adhering to the outside of the cable 8 are scraped off and then collected in the collection box 772 by the guide plate 771, achieving the cleaning effect and preventing impurities and debris from affecting subsequent coating operations.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
