Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a circulating cooling system for a vertical cable production line. Background Technology

[0002] A vertical cable production line is a specialized piece of equipment for cable manufacturing. It typically utilizes a vertical layout to optimize space and improve production efficiency. Cable production is completed through steps including a raw material supply system, extruder traction equipment, a cooling system, and a winding system. The cooling system is used to rapidly cool the extruded cable, ensuring its structural stability. Normally, during cable production, the extruded cable is cooled through an open cooling water tank. The cooling water circulates within the tank, surrounding the cable surface to rapidly reduce temperature and prevent surface defects. However, vertical production lines are not well-suited for using circulating open cooling water tanks. This method requires a large amount of cooling water, has a relatively long cooling time, and is also inconvenient for later maintenance. Therefore, to further improve the practicality of the device, we provide a circulating cooling system for a vertical cable production line to address these issues. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a circulating cooling system for a vertical cable production line. By setting a spiral cooling water pipe on the inner surface of the protective tube and surrounding the surface of the cable after extrusion, the circulating cooling water in the cooling water tank, combined with the cold air fan set at the bottom of the protective tube, further cools the cable in the protective tube, and helps to maintain the temperature of the cooling water pipe lower than the temperature of the cable. Then, the heat dissipation area of ​​the protective tube is increased by the heat dissipation fins fixedly connected in the heat dissipation groove set inside the protective tube. This not only allows the cable to be cooled in a relatively stable cooling environment, but also makes the temperature inside the protective sleeve relatively uniform, reducing the impact of temperature fluctuations.

[0004] This utility model also provides a circulating cooling system for a vertical cable production line, comprising: a vertical tower; a raw material conveyor fixedly connected to the inner bottom surface of the vertical tower; an extruder fixedly connected to the raw material conveyor via a conveying pipe; a traction pipe fixedly connected to the output end of the extruder; a cooling water tank fixedly connected to the inner bottom surface of the vertical tower; a water inlet pipe fixedly connected to the upper surface of the cooling water tank; a support frame fixedly connected to the outer surface of the cooling water tank; a protective pipe fixedly connected inside the support frame; a heat dissipation groove provided inside the protective pipe; several heat dissipation fins fixedly connected inside the protective pipe; a cooling water pipe fixedly connected to the inner wall of the protective pipe; one end of the water inlet pipe connected to the bottom end of the cooling water pipe; and two air coolers fixedly connected to the upper surface of the cooling water tank.

[0005] According to the circulating cooling system for a vertical cable production line described in this utility model, the bottom surface of the protective pipe is adjacent to the opening of the traction pipe, and a support plate is fixedly connected between the protective pipe and the support frame. This enhances the robustness and stability of the support frame.

[0006] According to the circulating cooling system for a vertical cable production line described in this utility model, the air outlet of the cooler corresponds to the pipe opening at the bottom of the protective pipe, and the bottom surface of the cooler is fixedly connected to the cooling water tank via a bracket. This system is used to accelerate the cooling speed of the cable and help maintain the temperature of the cooling water pipe.

[0007] According to the circulating cooling system for a vertical cable production line of this utility model, a fixed frame is fixedly connected to the upper end of the support frame, a traction roller shaft is fixedly connected to the upper surface of the fixed frame, and a traction frame is fixedly connected to the upper surface of the support frame. This system is used to pull the cable as it rises to the top of the protective pipe.

[0008] According to the circulating cooling system for a vertical cable production line of this utility model, a fixed plate is rotatably connected to the upper surface of the cooling water tank via a rotating shaft. An electric take-up roller is fixedly connected to the upper surface of the fixed plate, and a limit groove is formed on the outer surface of the fixed plate for use as a limit rod to fix the fixed plate.

[0009] According to the circulating cooling system for a vertical cable production line described in this utility model, a limiting rod is rotatably connected to the front surface of the cooling water tank, and the width of the limiting rod is the same as the width of the limiting groove. This is to facilitate the limiting rod in fixing the fixing plate.

[0010] According to the circulating cooling system for a vertical cable production line described in this utility model, the electric take-up roller is positioned close to the inner surface of the vertical tower. This creates a slope at a certain angle between the roller and the traction roller's moving shaft, facilitating cable winding.

[0011] According to the circulating cooling system for a vertical cable production line described in this utility model, a water outlet pipe is fixedly connected to the rear surface of the cooling water tank, and one end of the water outlet pipe is connected to the upper end of the cooling water pipe. This allows the cooling water tank to continuously circulate and supply cooling water, ensuring efficient cooling of the cables.

[0012] Beneficial effects: By setting a spiral cooling water pipe on the inner surface of the protective tube and surrounding the surface of the newly extruded cable, the circulating cooling water in the cooling water tank, combined with the cold air fan at the bottom of the protective tube, further cools the cable in the protective tube and helps to maintain the temperature of the cooling water pipe below the temperature of the cable. Then, the heat dissipation area of ​​the protective tube is increased by the heat dissipation fins fixedly connected in the heat dissipation groove inside the protective tube. This not only allows the cable to cool in a relatively stable cooling environment, but also makes the temperature inside the protective sleeve relatively uniform, shortens the cooling time and reduces the impact of temperature fluctuations.

For easy connection to the water pump in the cooling water tank 4 and water supply, a support frame 5 is fixedly connected to the outer surface of the cooling water tank 4 to fix and support the protective pipe 6. The protective pipe 6 is fixedly connected inside the support frame 5 to form an effective cooling environment. The protective pipe 6 has heat dissipation grooves inside to combine with heat dissipation fins 8 to accelerate heat dissipation. Several heat dissipation fins 8 are fixedly connected inside the protective pipe 6 to increase the heat dissipation area of ​​the protective pipe 6. A cooling water pipe 7 is fixedly connected to the inner wall of the protective pipe 6 to be adjacent to the pulled cable and to dissipate heat from the cable surface. One end of the water inlet pipe 41 is connected to the bottom end of the cooling water pipe 7 to supply cooling water through the water pump in the cooling water tank 4. A cold air fan 11 is fixedly connected to the upper surface of the cooling water tank 4. Two cold air fans 11 are symmetrically arranged to blow cold air onto the outer surface of the cable to help maintain the air temperature around the cooling water pipe 7 lower than the cable temperature, accelerate evaporation and heat exchange, and further reduce the temperature.

[0023] The bottom surface of the protective pipe 6 is adjacent to the opening of the traction pipe. A support plate 51 is fixedly connected between the protective pipe 6 and the support frame 5 to enhance the strength and stability of the support frame 5 and facilitate the rapid cooling of the pulled cable inside the protective pipe 6. The air outlet of the cooler 11 corresponds to the opening at the bottom of the protective pipe 6. The bottom surface of the cooler 11 is fixedly connected to the cooling water tank 4 through a bracket to accelerate the cooling speed of the cable and help maintain the temperature of the cooling water pipe 7. A fixing frame 9 is fixedly connected to the upper end of the support frame 5. A traction roller shaft 10 is fixedly connected to the upper surface of the fixing frame 9. A traction frame is fixedly connected to the upper surface of the support frame 5 for pulling the cable when it rises to the top of the protective pipe 6, facilitating subsequent orderly winding. A fixed plate 13 is rotatably connected to the upper surface of the cooling water tank 4 via a rotating shaft. An electric winding roller 12 is fixedly connected to the upper surface of the fixed plate 13 for automatically winding the cable. A limit groove 1301 is formed on the outer surface of the fixed plate 13 for a limit rod 14 to fix the fixed plate 13. A limit rod 14 is rotatably connected to the front surface of the cooling water tank 4. The width of the limit rod 14 is the same as the width of the limit groove 1301, which facilitates the fixation of the fixed plate 13 and ensures its stability. The electric winding roller 12 is positioned close to the inner surface of the vertical tower 1 to form a slope at a certain angle with the traction roller shaft 10, which facilitates the cable winding operation. A water outlet pipe 42 is fixedly connected to the rear surface of the cooling water tank 4. One end of the water outlet pipe 42 is connected to the upper end of the cooling water pipe 7, which is used to transport the cooling water after cooling the cable back to the cooling water tank 4, so that the cooling water tank 4 can continuously circulate and transport cooling water to ensure that the cable has an efficient cooling effect.

[0024] Working principle: When using the circulating cooling system of this vertical cable production line, the raw material enters from the hopper of the raw material conveyor 2 and is transferred to the extruder 3 for plasticizing and extrusion. At the same time, the extruded cable is pulled by the traction pipe into the protective pipe 6 fixedly connected to the support frame 5, and then pulled to the traction frame on the top surface of the support frame 5. It is then transferred by the traction roller shaft 10 to the electric winding roller 12 connected to the fixed plate 13 for winding. At the same time, when the cable enters the protective pipe 6, the water pump in the cooling water tank 4 delivers cooling water to the cooling water pipe 7 through the water inlet pipe 41. The cooling water pipe 7 is in contact with the surface of the cable. The cooling effect of the air cooler 11 on the cable is to quickly cool it down. Combined with the air cooler 11 supplying cold air from the bottom of the protective tube 6 and the interaction between the air cooler 11 and the heat sink 8 of the protective tube 6, the cooling effect on the cable is accelerated. When the electric winding roller 12 winds up the cable, the limiting rod 14 is flipped upward and locked in the limiting groove 1301, which serves to fix the fixing plate 13. After winding is completed, the limiting rod 14 is removed and the position of the fixing plate 13 is rotated to facilitate the removal of the cable. At the same time, the water cooled in the cooling water pipe 7 is then transported to the cooling water tank 4 through the outlet pipe 42 to form a circulating cooling water.
