Description

Technical Field

[0001] This utility model relates to the field of wire and cable production technology, specifically to an insulation layer coating device for cable production. Background Technology

[0002] In modern power and communication systems, cables serve as the core transmission carrier. The performance and quality of their insulation layer directly determine the reliability, lifespan, and safety of the cables. Insulation layer coating is a key process in cable production, and its core objective is to uniformly and densely coat the conductor (cable core) with insulating materials (such as polyethylene, cross-linked polyethylene, etc.). However, traditional insulation coating processes still face significant technical bottlenecks in the cooling and compaction stages, hindering further improvements in product quality and production efficiency. In the cooling stage, traditional methods often employ direct-flow water tanks or spray cooling, which can easily lead to laminar flow or short-circuiting, resulting in low and uneven cooling efficiency. This causes large temperature differences between the inside and outside of the insulation layer, potentially generating thermal stress, deformation, uneven shrinkage, and even affecting insulation performance (such as crystallinity). Furthermore, the heat exchange efficiency between the cooling water and the inner wall of the coating mold is low, and cooling uniformity is poor. Uneven cooling processes can easily cause differences in the internal microstructure of the insulation material (such as crystallinity and molecular orientation), forming stress concentration points. This, in turn, degrades the electrical properties (such as dielectric strength and insulation resistance) and mechanical properties (such as tensile strength and resistance to environmental stress cracking) of the insulation layer, ultimately affecting the long-term operational stability of the cable product. To address this, an insulation coating device for cable production is proposed. Utility Model Content

[0003] The purpose of this invention is to provide an insulation layer coating device for cable production, which solves the technical problems of low and uneven cooling efficiency of traditional devices, resulting in large temperature differences between the inside and outside of the insulation layer, which may cause thermal stress, deformation, uneven shrinkage, and even affect the insulation performance. The invention effectively promotes the stable formation of the microstructure of the insulation layer, obtains a denser and more uniform material structure, and improves the electrical and mechanical properties of the product.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an insulation layer coating device for cable production, comprising a platform, a cooling component, and a pressing component. The cooling component is disposed in the middle of the upper surface of the platform, and the pressing component is disposed at the rear end of the upper surface of the platform. The cooling component includes a first connecting frame, which is fixedly connected to the middle of the upper surface of the platform. A mounting block is fixedly connected to the middle of the inner top surface of the first connecting frame, and a cooling pipe is fixedly connected to the lower surface of the mounting block. A cooling channel is formed inside the cooling pipe. A water pump is disposed in the middle of the rear end of the upper surface of the first connecting frame, and a water storage tank is disposed in the middle of the front end of the upper surface of the first connecting frame. The water suction end of the water pump passes through a pipe to the inner wall of the water storage tank, and the water discharge end of the water pump passes through a pipe to the interior of the cooling channel.

[0005] Preferably, the front end of the cooling channel extends into the interior of the water storage tank via a pipe. Multiple semiconductor cooling chips are provided on both sides of the water storage tank, and a cover plate is provided on the upper surface of the water storage tank. The semiconductor cooling chips can cool the coolant to ensure its temperature, and the water storage tank can be opened through the cover plate.

[0006] Preferably, the clamping assembly includes a second connecting frame, which is fixedly connected to the upper surface of the platform near the rear end. Multiple damping tubes are fixedly connected to the front and rear ends of the inner wall of the second connecting frame, and the damping tubes can adapt to the actual contour changes of the cable core in real time.

[0007] Preferably, a compaction roller is fixedly connected to one side of the damping tube near the center of the second connecting frame, and a rubber sleeve is fixedly connected to the outer wall of the compaction roller. The insulation layer can be compacted by the compaction roller.

[0008] Preferably, a connecting block is fixedly connected to the middle of the rear end of the upper surface of the platform, and a covering head is fixedly connected to the upper surface of the connecting block, through which the cable can be covered.

[0009] Preferably, mounting plates are fixedly connected to both sides of the front end of the upper surface of the platform. A servo motor is fixedly connected to the middle of the outer wall of one side of the mounting plate. A rotating rod is fixedly connected to the output end of the servo motor. The side of the rotating rod away from the servo motor is rotatably connected to the mounting plate. The servo motor drives the rotating rod to rotate, thereby collecting the cable after cooling.

[0010] Preferably, a control panel is fixedly connected to one side of the rear end of the upper surface of the platform. The water pump, the semiconductor cooling chip and the servo motor are all electrically connected to the control panel. The control panel facilitates operation by the staff, and the electrical connection facilitates signal transmission and reception.

[0011] Preferably, each of the four corners of the lower surface of the platform is fixedly connected to a support leg, and each support leg is fixedly connected to a support base. The support legs can support the platform, and the support bases can improve the stability of the support legs.

[0012] This invention provides an insulation layer coating device for cable production. It has the following advantages: (1) This utility model continuously draws coolant from the water tank into the cooling channel through a water pump. Through the spiral flow guiding structure design, the cooling water is forced to form a high-speed turbulent state, so that the cooling water can closely adhere to the wall of the cooling pipe and move forward in a spiral shape. During the flow process, a strong vortex effect is formed, which not only significantly improves the heat transfer coefficient, but also ensures the uniformity of the cooling process. Through the fast and uniform cooling method, the stable formation of the microstructure of the insulation layer can be effectively promoted, a denser and more uniform material structure can be obtained, and the electrical and mechanical properties of the product can be improved.

[0013] (2) The present invention can adapt to the actual contour changes of the cable core in real time by setting a damping tube to connect the compaction roller device. During the cable production process, the damping tube will automatically adjust the pressure distribution of the compaction roller according to the irregular shape of the cable core surface, so as to always maintain a uniform and constant clamping force, effectively ensuring the uniformity of the insulation layer thickness, avoiding the problem of local thinness or thickness common in traditional processes, and better absorbing the small vibrations generated by the cable during high-speed operation, making the entire production process more stable and reliable. This not only improves the product quality, but also significantly improves the production efficiency, providing a strong guarantee for high-speed continuous production and helping to achieve higher production speed targets.

Multiple semiconductor cooling chips 27 are provided on both sides of the water storage tank 26, and a cover plate 28 is provided on the upper surface of the water storage tank 26.

[0019] Furthermore, in this embodiment, the coolant in the water storage tank 26 is continuously drawn into the cooling channel 24 by the water pump 25. Through the spiral flow guide structure design, the cooling water is forced to form a high-speed turbulent state, so that the cooling water can closely adhere to the wall of the cooling pipe 23 and move forward in a spiral shape.

Example

[0020] Based on Embodiment 1, a preferred embodiment of the insulation layer coating device for cable production provided by this utility model is, for example...

Multiple damping tubes 32 are fixedly connected to the front and rear ends of the inner wall of the second connecting frame 31. A compaction roller 33 is fixedly connected to one side of the damping tube 32 near the center of the second connecting frame 31, and a rubber sleeve 34 is fixedly connected to the outer wall of the compaction roller 33. A connecting block 4 is fixedly connected to the middle of the rear end of the upper surface of the platform 1, and a covering head 5 is fixedly connected to the upper surface of the connecting block 4; Mounting plates 6 are fixedly connected to both sides of the front end of the upper surface of the platform 1.

[0021] Furthermore, in this embodiment, the damping tube 32 connected to the compaction roller 33 device can adapt to the actual contour changes of the cable core in real time.

This effectively ensures the uniformity of the insulation layer thickness, avoids the problem of local over-thinness or over-thickness common in traditional processes, and can better absorb the small vibrations generated during high-speed cable operation, making the entire production process more stable and reliable. This not only improves product quality but also significantly increases production efficiency, providing a strong guarantee for high-speed continuous production and facilitating the achievement of higher production speed targets.

[0022] In use, the cable is wrapped by passing it through the wrapping head 5. Then, when the cable passes through the second connecting frame 31, the device connected to the compaction roller 33 through the damping tube 32 can adapt to the actual contour changes of the cable core in real time. During the cable production process, the damping tube 32 will automatically adjust the pressure distribution of the compaction roller 33 according to the irregular shape of the cable core surface, so as to always maintain a uniform and constant clamping force, effectively ensuring the uniformity of the insulation layer thickness and better absorbing the small vibrations generated by the cable during high-speed operation. After being compacted, the cable passes through the cooling pipe 23. The water pump 25, controlled by the control panel 9, continuously draws the coolant from the water tank 26 into the cooling channel 24. Through the spiral flow guide structure design, the cooling water is forced to form a high-speed turbulent flow state, so that the cooling water can closely adhere to the wall of the cooling pipe 23 and move forward in a spiral shape. During the flow process, a strong vortex effect is formed, which not only significantly improves the heat transfer coefficient, but also ensures the uniformity of the cooling process. Through the rapid and uniform cooling method, the stable formation of the microstructure of the insulation layer can be effectively promoted, a denser and more uniform material structure can be obtained, and the electrical and mechanical properties of the product can be improved. During the cooling process, the coolant can be cooled by the semiconductor cooling chip 27 inside the water tank 26 to maintain the temperature of the coolant. Finally, the servo motor 7 drives the rotating rod 8 to rotate, thereby collecting the cooled cables.
