Description
Technical Field
[0001] This utility model relates to the technical field of cooling and shaping mechanisms, specifically to a cooling and shaping mechanism for MPP / PE cable protection pipes. Background Technology
[0002] MPP / PE cable protection pipes are two types of buried pipes made of polymer materials as the base material, specifically designed to protect underground cables. They are used to isolate the cables from soil corrosion, mechanical impact, and groundwater erosion, preventing cable damage. They are widely used in municipal engineering and other scenarios. In the production process of cable protection pipes, the main processes include raw material processing, extrusion molding, cooling, and traction cutting. During the cooling stage after the rapid molding of the protection pipe, due to the high temperature extrusion of various raw materials in the extruder, the temperature of the formed cable protection pipe is too high, resulting in a "soft" state. Therefore, a cooling and shaping process is required. Most existing cooling devices are water-cooled, which use multiple pipes with spray nozzles at the top of the cooling chamber to spray cold water onto the cable protection pipes transferred from the extruder outlet through the conveying mechanism, thereby cooling and shaping the pipes sequentially. However, this method of only setting pipes at the top of the cooling chamber and spraying cold water downwards onto the cable protection pipes results in a difference in cooling effect between the upper and lower parts of the cable protection pipe, even if the cold water sprayed on the cable protection pipes slides down the pipe wall and contacts the bottom of the cable protection pipe. This leads to poor shaping effect of the cable protection pipes. Utility Model Content
[0003] To overcome the above-mentioned defects, the present invention provides a cooling and shaping mechanism for MPP / PE cable protection pipes, which solves the technical problem in the prior art where cold water is only sprayed downwards towards the cable protection pipe, resulting in a difference in cooling effect between the upper and lower parts of the cable protection pipe and thus poor shaping effect.
[0004] According to one aspect, at least one embodiment of the present invention provides a cooling and shaping mechanism for an MPP / PE cable protection pipe, applied to an extruder. The mechanism includes a cooling chamber disposed on one side of the extruder, a water storage tank, a water pump, a water outlet pipe, a lubricating and cooling component, and a cooling mechanism. The water storage tank is disposed at the bottom of the cooling chamber and communicates with it. The water pump is installed on the cooling chamber, and its input end is connected to the bottom of the water storage tank via an inlet pipe. One end of the water outlet pipe is connected to the output end of the water pump, and the other end is located above one end of the extruder. The lubricating and cooling component is disposed at one end of the extruder and is used to lubricate and pre-cool the protection pipe moving within the extruder. The cooling mechanism is disposed within the cooling chamber and is used to circulate cold water onto the protection pipe within the cooling chamber.
[0005] Preferably, the lubrication and cooling component includes a water outlet, a collection chamber, and a return pipe. One end of the water outlet is connected to the water outlet, and one end of the water outlet is inclined toward the protective pipe. The collection chamber is fixedly connected to the extruder and is located below the water outlet. One end of the return pipe is connected to the bottom of the collection chamber, and the other end is connected to the water storage tank.
[0006] Furthermore, the cooling mechanism includes a water collection pipe, a spray ring pipe, spray heads, and an air-cooling assembly. The water collection pipe is fixedly installed on the cooling chamber and is connected to the water outlet pipe through a connecting pipe. Multiple spray ring pipes are sleeved on the outside of the protective pipe, and all of the multiple spray ring pipes are connected to the water collection pipe. Multiple spray heads are arranged circumferentially on the spray ring pipes. The air-cooling assembly is installed inside the cooling chamber and is used to blow air to cool the protective pipe and cool the water in the water storage tank.
[0007] Furthermore, the air-cooling assembly includes a partition, a fan, and a circulation space. The partition is fixedly installed inside the cooling chamber and divides the cooling chamber into a water-cooled chamber and an air-cooled chamber. Two fans are installed on the cooling chamber to blow air towards the air-cooled chamber. A circulation space is provided on the water storage tank and communicates with the air-cooled chamber to transfer airflow. The water storage tank also has multiple connecting holes, all of which communicate with the circulation space to transfer cold air into the water storage tank and to cool the water source by blowing air through it.
[0008] As a further embodiment of this application, the return pipe is tilted downward toward the water storage tank, and the other end is positioned above the connecting hole.
[0009] As a further improvement in this application, a water flow slope is provided on the bottom wall of the water-cooling cavity to guide the water splashed on the water-cooling cavity into the water storage tank.
[0010] Based on the aforementioned scheme, in order to uniformly and fully spray cold water onto the surface of the protective tube, multiple spray heads are tilted toward the extruder.
[0011] Furthermore, based on the aforementioned solution, the cooling chamber is provided with an installation port for installing the fan and for air circulation between the cooling chamber and the outside.
[0012] The beneficial effects of this utility model are as follows: In this invention, through the cooperation of a water storage tank, a water pump, a water outlet pipe, a lubrication and cooling component, and a cooling mechanism, cold water is drawn out and transferred to the water outlet by starting the water pump. The cold water sprays water onto the forming protective tube (not fully formed) at one end of the extruder, which can both lubricate and cool it down in advance. Then the cold water flows into the collection chamber and flows back to the water storage tank through the return pipe for subsequent use. As the cold water flows through the outlet pipe, some of it is transferred to the collection pipe via the connecting pipe and then dispersed into multiple spray ring pipes, reaching multiple spray heads. While the protective pipe moves within the cooling chamber, multiple spray heads spray cold water onto the protective pipe, effectively cooling it. Two fans are activated to blow air onto the protective pipe within the air-cooling chamber, and the air flows within the chamber. The cold air enters the water storage tank through the circulation space and multiple connecting holes, positioned above the water source. This not only cools the returning water in the storage tank but also allows air to circulate within the water-cooling chamber, achieving both cooling and transferring hot air to the outside. This results in excellent cooling of the protective pipe. Attached Figure Description

[0022] like Figures 1-4As shown, it illustrates an MPP / PE cable protection tube cooling and shaping mechanism according to an embodiment of the present invention. It is applied to an extruder 1 and includes a cooling chamber 2, which is set on one side of the extruder 1. The cooling chamber 2 is at the same height as the extruder 1 and keeps the protection tube 7 horizontal. It should be added that the extruder 1 is provided with a conveying traction structure for traction and conveying of the protection tube 7 formed on the extruder 1. Generally, there are two conveying rollers. The rotation of the conveying rollers drives the formed protection tube 7 "clamped" in the middle of the conveying rollers to move. It also includes a water storage tank 3, a water pump 4, a water outlet pipe 6, a lubrication and cooling component, and a cooling mechanism. The water storage tank 3 is located at the bottom of the cooling chamber 2 and is connected to the cooling chamber 2. The water pump 4 is installed on the cooling chamber 2 and its input end is connected to the bottom of the water storage tank 3 through the water inlet pipe 5. By starting the water pump 4, the water pump 4 draws out the cold water at the bottom of the water storage tank 3 and transfers it out of the water storage tank 3 through the water inlet pipe 5. like Figure 1 As shown, one end of the water outlet pipe 6 is connected to the output end of the water pump 4, and the other end is located above one end of the extruder 1. A lubrication and cooling component is installed at one end of the extruder 1 to lubricate and pre-cool the protective tube 7 moving inside the extruder 1. The lubrication and cooling component includes a water outlet head 8, a collection chamber 9, and a return pipe 10. One end of the water outlet pipe 6 is connected to the water outlet head 8, and one end of the water outlet head 8 is inclined towards the protective tube 7. The collection chamber 9 is fixedly connected to the extruder 1 and is located below the water outlet head 8. One end of the return pipe 10 is connected to the bottom end of the collection chamber 9, and the other end is connected to the water storage tank 3. The water pump 4 then cools the water... Water is drawn out and sequentially transferred through inlet pipe 5, water pump 4, and outlet pipe 6 to outlet head 8. Cold water sprays onto the forming protective tube 7 (not fully formed) at one end of extruder 1, which serves both as lubrication and pre-cooling. It should be noted that a control valve is installed on the end of outlet pipe 6 near outlet head 8 to adjust the water flow rate of outlet head 8. Generally, the water flow is natural and not sprayed. The cold water flowing on the protective tube 7 at one end of extruder 1 flows into collection bin 9 and then through return pipe 10 into water storage tank 3 for subsequent use. like Figures 2-4As shown, a cooling mechanism is installed inside the cooling chamber 2 to circulate cold water onto the protective pipe 7 within the cooling chamber 2. The cooling mechanism includes a water collection pipe 11, a spray ring pipe 13, spray heads 14, and an air-cooling assembly. The water collection pipe 11 is fixedly installed on the cooling chamber 2 and is connected to the water outlet pipe 6 via a connecting pipe 12. Multiple spray ring pipes 13 are sleeved on the outside of the protective pipe 7, and all of the multiple spray ring pipes 13 are connected to the water collection pipe 11. The cross-sectional area of the spray ring pipe 13 is larger than that of the protective pipe 7. Multiple spray heads 14 are arranged circumferentially on the spray ring pipe 13 to uniformly spray the surface of the protective pipe 7. The water is sprayed with cold water. Multiple spray heads 14 are tilted towards the extruder 1. A water flow slope 21 is provided on the bottom wall of the water cooling chamber 16 to guide the water splashed on the water cooling chamber 16 to the water storage tank 3. The cold water in the water storage tank 3 is pumped out by starting the water pump 4. During the flow of the cold water in the outlet pipe 6, part of the cold water is transferred to the water collection pipe 11 through the connecting pipe 12 and dispersed to multiple spray ring pipes 13 and reach multiple spray heads 14. While the protective pipe 7 moves in the cooling chamber 2, multiple spray heads 14 spray cold water towards the protective pipe 7 to cool and reduce the temperature of the protective pipe 7. The air-cooling assembly is installed inside the cooling chamber 2 to cool the protective pipe 7 and the water in the water storage tank 3. The air-cooling assembly includes a partition 15, a fan 18, and a flow space 19. The partition 15 is fixedly installed inside the cooling chamber 2, dividing it into a water-cooled chamber 16 and an air-cooled chamber 17. After the spray head 14 sprays cold water onto the protective pipe 7, the splashed water flows through the inner wall of the water-cooled chamber 16 and the water flow slope 21 into the water storage tank 3. Two fans 18 are installed on the cooling chamber 2 to blow air into the air-cooled chamber 17. An installation port 22 is provided on the cooling chamber 2 for installing the fans 18 and for air circulation between the cooling chamber 2 and the outside air. The water storage tank 3 has a flow space 19 for air circulation. Space 19 is connected to air-cooled cavity 17 for transferring airflow. Multiple connecting holes 20 are also provided on water tank 3. All connecting holes 20 are connected to circulation space 19 for transferring cold air into water tank 3 and cooling water source by blowing air through circulation space 19. Specifically, by starting two fans 18 and blowing air towards the protective tube 7 in air-cooled cavity 17, and the air flows in air-cooled cavity 17, the cold air will enter water tank 3 through circulation space 19 and multiple connecting holes 20 and be above water source. It can cool the water source flowing back into water tank 3 and can also move into water-cooled cavity 16 for air flow. It not only plays a role in cooling but also transfers hot air to the outside. The return pipe 10 is tilted downward toward the water storage tank 3, and the other end is above the connecting hole 20. This allows the steadily rising water source to be concentrated and transferred to the upper part of the water source in the water storage tank 3. Working principle: When this MPP / PE cable protection pipe cooling and shaping mechanism is applied to the extruder 1, the extruder 1 is running and the protective pipe 7 is being extruded. The extruded protective pipe 7 is being pulled and conveyed. One end of the protective pipe 7 passes through the cooling chamber 2 for conveying. By starting the water pump 4, cold water is drawn out and transferred to the water outlet 8 through the water inlet pipe 5, the water pump 4 and the water outlet pipe 6 in sequence. The cold water sprays water on the formed protective pipe 7 (not fully formed) at one end of the extruder 1, which can both lubricate and cool it down in advance. Then the cold water will flow into the collection chamber 9 and flow into the water storage tank 3 through the return pipe 10 for subsequent use. As the cold water flows through the outlet pipe 6, some of it is transferred to the collection pipe 11 via the connecting pipe 12 and dispersed into multiple spray ring pipes 13, reaching multiple spray heads 14. While the protective pipe 7 moves within the cooling chamber 2, multiple spray heads 14 spray cold water onto the protective pipe 7 to cool it down. By activating two fans 18, air is blown onto the protective pipe 7 within the air-cooling chamber 17, and the air flows within the air-cooling chamber 17. The cold air enters the water storage tank 3 through the circulation space 19 and multiple connecting holes 20, and is positioned above the water source. This cools the returning water source in the water storage tank 3 and allows it to move into the water-cooling chamber 16 for air circulation. This not only cools the water but also transfers hot air to the outside, resulting in a good cooling effect on the protective pipe 7.
