The triangular stopper is in sliding contact with multiple metal sheets during the rotation with the connecting shaft, which is conducive to continuous vibration of the metal sheets, thereby facilitating the generation of a large amount of water mist on the surface of the water body inside the water tank, which can effectively increase the moisture content in the gas and make the surface of the pipe to be cooled moist, so that the moisture on the surface of the pipe absorbs the heat of the pipe during evaporation, thereby further improving the cooling efficiency of the pipe.

[0020] 4.

An embedded hood 12 is installed inside the guide hood 11, and the guide hood 11 and the embedded hood 12 are both movably sleeved on the outside of the pipe to be cooled. The guide hood 11 and the embedded hood 12 are both conical in shape, and the smaller diameter ends of the guide hood 11 and the embedded hood 12 are both located on the right side. A plurality of connecting plates 13 equidistantly distributed around the circumference are fixedly installed between the guide hood 11 and the embedded hood 12, and a wind cavity 32 is formed between the guide hood 11, the embedded hood 12 and the two adjacent connecting plates 13.

[0035] The air nozzle 8 is located inside the wind cavity 32, and a plurality of balls 14 equidistantly distributed in a circle are movably embedded on the inner wall of the air deflector 11. An annular rolling groove 31 is provided on the outer side of the support tube 9, and the plurality of balls 14 are in rolling contact with the support tube 9 through the annular rolling groove 31.

[0038] Working principle: PPR pipes pass through the inner side of the guide assembly and the annular tube 7 under the traction of the traction equipment, and multiple conveyor rollers 2 rotate to convey the pipes (when cooling different types of PPR pipes, it is only necessary to change the height of multiple conveyor rollers 2 and limit guide rollers, or change the height of the guide assembly and the annular tube 7 to make the PPR pipes concentric with the guide cover 11. The method of changing the height can be based on the existing technology, which will not be described here), the blower 3 is operated to make the gas ejected through multiple air nozzles 8, and the air ejected by the air nozzles 8 The gas will be blocked by the embedded cover 12 and the connecting plate 13, and then blown out along the inner wall of the conical guide cover. Since the gas is blown out from the end with a smaller diameter of the guide cover 11, multiple streams of gas will converge along the inner wall of the guide cover 11, so that when the gas is blown out through the guide cover 11, the gas can be evenly distributed on the outside of the pipe to be cooled, so that the heat on the surface of the pipe is evenly dissipated, and when the gas is blown out from the end with a smaller diameter of the conical guide cover 11, the gas flow rate can be increased, so that the more heat the gas takes away per unit time, the better the cooling effect on the pipe;

[0039] When the blower 3 is running, the air pump 18 runs synchronously. The air pump 18 delivers the gas in the workshop into the water tank 16 through the conduit three 17. Since one end of the conduit three 17 connected to the water tank 16 is close to the lower end of the water tank 16, after the gas enters the water tank 16, it will exchange heat with the cold water in the water tank 16, so that the temperature of the gas entering the blower 3 is reduced, preventing the high workshop temperature from affecting the cooling effect of the gas on the pipe.

[0040] Example 2: Please refer to Figure 5 , this embodiment further explains the first embodiment, the vibration component includes an embedded tube 19 installed inside the water tank 16, and a plurality of metal sheets 20 distributed at equal distances are fixedly installed on the inner side of the embedded tube 19, a connecting shaft 21 is fixedly embedded at the center of the lower end of the installation shaft of the impeller of the blower 3, and the connecting shaft 21 is rotatably connected to the water tank 16 through a sealed bearing, and two symmetrically distributed levers 22 are fixedly installed on the outer side of the connecting shaft 21, and the lever 22 is close to the lower end of the connecting shaft 21, and a triangular stopper 23 is fixedly embedded at one end of the lever 22 away from the connecting shaft 21, and the connection between the triangular stopper 23 and the plurality of metal sheets 20 is in sliding contact, and the triangular stopper 23 is in sliding contact with the plurality of metal sheets 20 during rotation, so that the plurality of metal sheets 20 can vibrate, and a plurality of positioning pins 24 are fixedly installed on the inner wall of the water tank 16, and the plurality of positioning pins 24 are fixedly embedded on the side wall of the embedded tube 19.

[0041] In this embodiment: when the blower 3 is running, the connecting shaft 21 rotates synchronously with the impeller in the blower 3. The two triangular blocks 23 slide in contact with the multiple metal sheets 20 during the rotation with the connecting shaft 21, which can cause the metal sheets 20 to vibrate continuously, thereby facilitating the generation of a large amount of water mist on the surface of the water body inside the water tank 16. The water mist enters the blower 3 with the gas, which can effectively increase the moisture content in the gas. The gas containing a large amount of moisture is blown onto the surface of the pipe, which can make the surface of the pipe to be cooled moist, so that the moisture on the surface of the pipe absorbs the heat of the pipe during evaporation, further improving the cooling efficiency of the pipe.

[0042] Example 3: Please refer to Figure 4 , Figure 8 , this embodiment further explains the first embodiment, a driving assembly is installed on the outer side of the air deflector 11, and the driving assembly includes a rubber ring 25 fixedly sleeved on the outer side of the air deflector 11, and a movable plate 26 is installed on the lower side of the rubber ring 25. A plurality of convex teeth 27 distributed at equal distances are provided on the upper end of the movable plate 26, and the rubber ring 25 is in rolling contact with the movable plate 26 through the plurality of convex teeth 27, and the convex teeth 27 are used to increase the friction resistance between the movable plate 26 and the rubber ring 25, and a slider 28 is fixedly installed at the center of the lower end of the movable plate 26, and the connection between the slider 28 and the machine base 1 is sliding contact, and a reciprocating screw 29 is installed inside the slider 28, and the reciprocating screw 29 is linked with the conveying roller 2 through a synchronous wheel and a synchronous belt.

[0043] In this embodiment: during the process of the conveying rollers 2 conveying the pipe, two of the conveying rollers 2 drive the two reciprocating screws 29 to rotate through the synchronous wheels and the synchronous belts. During the rotation, the reciprocating screws 29 drive the movable plate 26 to reciprocate through the slider 28. During the reciprocating movement, the movable plate 26 drives the rubber ring 25 and the air guide cover 11 to reciprocate through a plurality of convex teeth 27. During the reciprocating rotation, the air guide cover 11 can prevent a certain air cavity 32 from always being located at the bottom and causing liquid accumulation, and prevent the air nozzle 8 located at the bottom from being immersed in the accumulated liquid and affecting the uniform distribution of gas.

[0044] Example 4: This embodiment further illustrates Example 1, and is an antibacterial and UV-resistant PPR pipe made by a cooling molding device. The PPR pipe includes a polypropylene anti-UV outer layer, a polypropylene layer, a glass fiber reinforced polypropylene layer, and an antibacterial polypropylene inner layer.

[0045] In this embodiment: the anti-UV outer layer of the PPR pipe has a strong anti-ultraviolet ability, and the PPR pipe is suitable for outdoor stacking and open-air use;

[0046] The polypropylene layer has good light-proof and pressure-resistant properties, and the pipe is not easy to breed algae, which is green and hygienic;
