DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 The utility model discloses a rapid cooling device for a plastic film blowing machine, comprising a base 1, a heat sink 2 is arranged on the surface of the base 1 through a supporting component, a suction hood 3 is installed at the bottom of the heat sink 2, a suction fan 4 is arranged at the position of the suction hood 3 inside the heat sink 2, and the top of the heat sink 2 is open;

[0023] The surface of the base 1 is provided with a heat dissipation pipe 5 installed inside the heat dissipation box 2 through a water circulation component, and the heat dissipation pipe 5 is located on the top of the suction fan 4.

[0024] Specifically, the support component includes two lifting cylinders 6, the two lifting cylinders 6 are respectively fixedly connected to the two sides of the top surface of the base 1, and the output shafts of the lifting cylinders 6 are fixedly connected to the bottom surface of the heat sink 2;

[0025] A guide rod 7 is fixedly connected to the bottom surface of the heat dissipation box 2 , a guide tube 8 is fixedly connected to the surface of the base 1 , and an inner side wall of the guide tube 8 is movably connected to the surface of the guide rod 7 .

[0026] In this embodiment, when the ambient temperature is high, the lifting cylinder 6 descends, thereby lowering the height of the heat sink 2, and then the air suction hood 3 can be closer to the working area of ​​the film blowing machine, so that the heat can be absorbed more effectively and the absorbed heat can be dissipated in time. During the movement of the heat sink 2, the guide rod 7 thereon will move along the guide tube 8, which can guide the heat sink 2, thereby stabilizing the movement of the heat sink 2.

[0027] Specifically, the water circulation component includes a water tank 9, a water pump 10 and a cooler 11. The water tank 9 is fixedly connected to the surface of the base 1. The water inlet of the water pump 10 is fixedly connected to the water outlet of the water tank 9 through a water pumping pipe. The water outlet of the water pump 10 is fixedly connected to a water supply pipe 12. The water outlet of the water supply pipe 12 is fixedly connected to a water distribution pipe 13. The water outlet of the water distribution pipe 13 is fixedly connected to the water inlet of the heat dissipation pipe 5.

[0028] The water outlet of the heat dissipation pipe 5 is fixedly connected to the water inlet of the water collecting pipe 14, the water outlet of the water collecting pipe 14 is fixedly connected to the return pipe 15, the water outlet of the return pipe 15 is fixedly connected to the water inlet of the cooler 11, and the water outlet of the cooler 11 is fixedly connected to the water tank 9 through a connecting pipe.

[0029] In this embodiment, after the water pump 10 delivers the water inside the water tank 9 to the water delivery pipe 12, it can enter the interior of multiple heat dissipation pipes 5 after being diverted by the water distribution pipe 13, thereby increasing the heat absorption area. The absorbed heat is then delivered to the interior of the return pipe 15 through the water collecting pipe 14, and finally sent back to the interior of the water tank 9 after being cooled by the cooler 11, thereby realizing circulation and dissipating heat.

[0030] Specifically, the surface of the heat dissipation tube 5 is fixedly connected with a heat dissipation fin 16 , and the surface of the heat dissipation fin 16 is provided with a vent hole 17 .

[0031] In this embodiment, the heat dissipation fins 16 are arranged on the surface of the heat dissipation tube 5 and inclined toward the suction fan 4, which can limit the speed of the gas and reduce the wind speed, so that the gas can be retained in the heat dissipation box 2 for a longer time, so that it can be more fully in contact with the heat dissipation tube 5, and then discharged. The vents 17 on the heat dissipation fins 16 can play a role of backflow and also have a certain diversion effect, so that the wind blocking effect of the heat dissipation fins 16 is not too large, which makes it inconvenient to discharge the gas.

[0032] Specifically, a radiator 18 is fixedly connected to the surface of the heat dissipation box 2 , and two radiators 18 are provided and symmetrically arranged on both sides of the radiator 18 .

[0033] In this embodiment, the surface of the radiator 18 is symmetrically fixedly connected with the radiator 18 , and the radiator 18 can assist in heat dissipation, so that the heat inside the heat dissipation box 2 is dissipated more quickly.

[0034] Specifically, a fixing plate 19 is mounted on the surface of the heat dissipation box 2 by screws, and a desiccant box 20 is fixedly connected to the surface of the fixing plate 19 . The desiccant box 20 is extended and arranged inside the heat dissipation box 2 .

[0035] In this embodiment, the desiccant box 20 can absorb the water vapor inside the heat sink 2 to prevent the humidity inside the radiator 18 from being too high. By removing the screws, the fixing plate 19 can be removed, and the dryer inside the desiccant box 20 can be replaced, thereby ensuring the drying effect.

[0036] The working principle and use process of the utility model: when in use, the heat dissipation box 2 set on the base 1 through the lifting cylinder 6 can adjust the height as needed. When the ambient temperature is high, the heat dissipation effect of the working area of ​​the film blowing machine is poor, which will cause a large amount of heat discharged by the exhaust fan to stay near the working area of ​​the film blowing machine. At this time, the lifting cylinder 6 is contracted, so that the height of the heat dissipation box 2 can be reduced, and then the air suction hood 3 can be closer to the working area of ​​the film blowing machine. The suction fan 4 is started, and the suction fan 4 can absorb the heat of the working area into the inside of the heat dissipation box 2 through the air suction hood 3. The suction fan 4 blows the gas containing heat to the heat dissipation pipe 5, and the inside of the heat dissipation pipe 5 is connected with flowing cooling water;

[0037] The interior of the water tank 9 is pre-stored with water, and the water pump 10 pumps the water into the interior of the water supply pipe 12. The water supply pipe 12 enters the interior of the heat dissipation pipe 5 through the water distribution pipe 13. The heat dissipation pipe 5 is provided with a plurality of heat dissipation pipes 5, which are arranged in a uniform array, and the surface of each heat dissipation pipe 5 is fixedly connected with a heat dissipation fin 16, which is inclined toward the suction fan 4, and the heat dissipation fin 16 is also provided with an air vent 17. When the suction fan 4 blows the gas containing heat to the heat dissipation pipe 5, the heat dissipation fin 16 can block the gas, reduce the gas wind speed, so that it can be more fully in contact with the heat dissipation pipe 5, and the air vent 17 thereon can further divert the gas to achieve a better heat dissipation effect. After the cooling water in the heat dissipation pipe 5 absorbs heat, it enters the water collecting pipe 14 with the water flow, and then enters the water return pipe 15 through the water collecting pipe 14. Finally, after being cooled by the cooler 11, the cooled water is sent back to the interior of the water tank 9 for recycling.

[0038] The surface of the heat sink 2 is also symmetrically fixed with two radiators 18, and the surface of the radiator 18 extends into the interior of the radiator 18, which can directly dissipate heat from the heat sink 2, thereby assisting in heat dissipation. Since hot gas contacts the heat pipe 5 and may generate water vapor, the desiccant box 20 fixedly connected by the fixing plate 19 can absorb the water vapor inside the heat sink 2, thereby keeping the inside of the heat sink 2 dry.

[0039] In summary, the rapid cooling device for the plastic film blowing machine can absorb the heat retained in the working area of ​​the film blowing machine into the inside of the heat dissipation box 2 by setting a radiator 18, a heat dissipation tube 5, a heat dissipation fin 16 and a suction fan 4, thereby increasing the heat dissipation speed and preventing the working environment from being affected.
