The raw materials include 70% - 75% by weight of high-density polyethylene (HDPE), 0.3% - 1.5% by weight of benzophenone (Chimassorb 81), 0.1% - 0.4% by weight of triazine (Tinuvin 1577), 0.3% - 0.8% by weight of hindered amine light stabilizer (HALS), 0.1% - 0.8% by weight of phosphite, 1% - 5% by weight of nano-titanium dioxide (TiO2), 0.1% - 0.3% by weight of flame retardant, 0.15% - 0.2% by weight of lubricant, 10% - 15% by weight of metallocene, and 2% - 3% by weight of carbon black. The first raw material mixing device and the third raw material mixing device mix various raw materials evenly and heat them to 190 - 200 °C. The first extruder and the third extruder use twin-screw extruders. The second raw material mixing device is used to store the raw materials for the intermediate layer of the water delivery pipe. The raw materials include 70% - 75% by weight of high-density polyethylene (HDPE) and 20% - 25% by weight of metallocene. The second extruder uses a single-screw extruder. The high-density polyethylene (HDPE) is HMCRP100N produced by PetroChina Company Limited, the benzophenone (Chimassorb 81) is UV-531 produced by BASF SE, the hindered amine light stabilizer (HALS) is UV-944 produced by BASF SE, the phosphite is IRGANOX 168 produced by BASF SE, the nano-titanium dioxide (TiO2) is LR-996 produced by Sichuan Longmang Group Co., Ltd., the metallocene is MVLDPE 5220G produced by Dow Chemical Company, and the carbon black is BP4350 produced by Cabot Corporation.

The cooling units 21 are connected to the cold air generating device 23 through cold air pipes 22, and the cooling units 21 are connected to the exhaust gas treatment device 25 through exhaust pipes 24. The cold air generating device 23 provides cooled air through compression refrigeration, and the exhaust gas treatment device 25 uses a medium-efficiency air filter to treat the discharged gas. As Figure 4 As shown, an upper gas isolation plate 211 and a lower gas isolation plate 212 are respectively arranged at both ends of the cooling unit 21. A pipe channel is formed between the upper gas isolation plate 211 and the lower gas isolation plate 212. A guiding ring 219 is arranged in the pipe channel, and the guiding ring 219 is used to position the water delivery pipe to ensure the stability of transmission. A first temperature sensor 215 and an air inlet 213 are arranged between the upper gas isolation plates 211. The air inlet 213 is connected to the cold air pipe 22, and an air inlet air pump 214 is arranged inside the air inlet 213. An exhaust port 216 and a second temperature sensor 218 are arranged between the lower gas isolation plates 212. The exhaust port 216 is connected to the exhaust pipe 24, and an exhaust air pump 217 is arranged inside the exhaust port 216. The first control module 26 controls the working process of the cooling and shaping device 2. During operation, the staff sets a target temperature through the first control module. The first control module receives the detection values of the first temperature sensor and the second temperature sensor in the cooling unit, calculates the average temperature, and controls the rotation speeds of the air inlet air pump and the exhaust air pump according to the difference between the average temperature and the target temperature. When the absolute value of the difference is less than the set error, the air inlet air pump and the exhaust air pump are set to the standard rotation speed. When the absolute value of the difference is greater than or equal to the set error and the average temperature is greater than the target temperature, the air inlet air pump and the exhaust air pump are increased. The greater the difference, the faster the rotation speed. When the absolute value of the difference is greater than or equal to the set error and the average temperature is less than the target temperature, the air inlet air pump and the exhaust air pump are decreased. The greater the absolute value of the difference, the slower the rotation speed. Each cooling unit works in coordination based on the target temperature to ensure the uniformity of cooling.

The cutting component 36 and the first clamping component 35 are connected to the first sliding block 34 through a telescopic rod. The cutting component 36 adopts a reciprocating electric saw and cuts the water delivery pipe by moving downward. When the downward moving distance is greater than the set threshold, it indicates that the cutting is completed. The lower moving track 33 is provided with a second sliding block 37. The second sliding block 37 can slide along the lower moving track driven by a motor. The second clamping component 38 is connected to the second sliding block 37 through a telescopic rod. The first clamping component 35 and the second clamping component 38 are oppositely arranged. The second control module 39 controls the working process of the traction cutting device 3. During operation, the staff sets the cutting length through the second control module. The laser rangefinder 31 measures the moving length of the water delivery pipe moving downward. When the moving length of the water delivery pipe reaches the cutting length, the first clamping component 35 and the second clamping component 38 are triggered to clamp the water delivery pipe. The first clamping component 35 and the second clamping component 38 move synchronously with the water delivery pipe. The cutting component 36 is started to move downward to cut the water delivery pipe. After the cutting is completed, the cutting component 36 is turned off to move upward to return to its original position. The moving speed of the first clamping component 35 and the second clamping component 38 is increased to separate the cut water delivery pipe. The cut water delivery pipe is transmitted to the tipping frame 4 through the first clamping component 35 and the second clamping component 38. After the transmission is completed, the first clamping component 35 and the second clamping component 38 are separated from each other and return to the initial position.
