At this time, the first circular groove 42 and the third circular groove 46 are relatively large in size. When the three enter the mold 3, the mold 3 limits the size of the three so that the three are combined, so that the PE water supply pipe is formed. Since the protective layer is installed inside the PE water supply pipe, the protective layer is a wire mesh, and the wire mesh can be unfolded and is rectangular after unfolding. Therefore, the wire mesh can be limited by the connecting device 6 so that the wire mesh forms a circle, which is arranged between the first layer of the pipe and the second layer of the pipe; Furthermore, the protective layer can be a heat-insulating material, and the heat-insulating material includes an aluminum foil mesh, a lead mesh, etc., so that the heat-insulating material is arranged between the first layer of the pipe and the second layer of the pipe, thereby improving the heat-insulating performance of the PE water supply pipe, and thus the PE water supply pipe of various functional models can be produced by the production method of the PE water supply pipe; The separation device 4 includes a first cylinder 41, a second cylinder 43, a third cylinder 45 and a fourth cylinder 47 connected to one end of the extrusion cylinder 2. A first circular groove 42 is provided between the first cylinder 41 and the second cylinder 43, a second circular groove 44 is provided between the second cylinder 43 and the third cylinder 45, and a third circular groove 46 is provided between the third cylinder 45 and the fourth cylinder 47. The adjusting device 5 comprises a first disc 51, a second disc 53, a third disc 55 and a fourth disc 57 connected to one end of the connecting device 6. A first clamping groove 52 is provided between the first disc 51 and the second disc 53, a second clamping groove 54 is provided between the second disc 53 and the third disc 55, and a third clamping groove 56 is provided between the third disc 55 and the fourth disc 57.

Example 2

[0026] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-3 The first clamping groove 52 and the third clamping groove 56 are both provided with a first airbag ring 58 and a second airbag ring 59, and the two first airbag rings 58 and the second airbag rings 59 are used to abut against the first layer tube and the second layer tube respectively; The first cylinder 41, the second cylinder 43, the third cylinder 45 and the fourth cylinder 47 are connected to the first disc 51, the second disc 53, the third disc 55 and the fourth disc 57 via a connecting device 6; The connecting device 6 includes a piston groove 61, a support cylinder 62, a first return spring 63 and a circulation groove 68. The interior of the piston groove 61 is slidably connected with the support cylinder 62. One ends of the four support cylinders 62 are connected to the first disc 51, the second disc 53, the third disc 55 and the fourth disc 57. The first return spring 63 is also installed on the outer surface of the support cylinder 62. A circulation groove 68 is arranged at one end of the support cylinder 62, and the circulation groove 68 is connected to the first airbag ring 58.

[0027] The first circular groove 42 is aligned with the first clamping groove 52, and the first layer of tubes is slidably connected at the first circular groove 42 and the first clamping groove 52; The second circular groove 44 is aligned with the second clamping groove 54, and the protection net is slidably connected at the second circular groove 44 and the second clamping groove 54; The third circular groove 46 and the third clamping groove 56 correspond to each other, and the second layer of tubes are slidably connected at the third circular groove 46 and the third clamping groove 56; The first cylinder 41, the second cylinder 43, the third cylinder 45 and the fourth cylinder 47 are all provided with an air-injection groove 48 and an air-intake groove 49. The air-injection groove 48 is used to blow air toward the outer surfaces of the first layer of tubes and the second layer of tubes. The support cylinder 62 is internally slidably connected with an extrusion disk 64, one end of the extrusion disk 64 is mounted with a slide rod 65, one end of the slide rod 65 is mounted with a piston disk 67, and a second return spring 66 is mounted between the piston disk 67 and the support cylinder 62; A pressure storage groove 10 is provided at one end of the piston groove 61 , a pressure relief groove 11 is installed between the piston groove 61 and the pressure storage groove 10 , a first hose 9 is provided at one end of the pressure storage groove 10 , and an air relief groove is provided at the other end of the piston groove 61 .

[0028] according to Figure 3 As shown, air is transmitted to the pressure storage tank 10 through the first hose 9, and pressure is stored in the pressure storage tank 10. Then, when the air pressure in the pressure storage tank 10 is greater than the pressure relief tank 11, the air pressure will push the pressure relief tank 11 open, so that the high-pressure gas in the pressure storage tank 10 enters the piston groove 61 through the pressure relief tank 11, and the piston plate 67 is pushed to slide toward one end by the high-pressure air, and the piston plate 67 pushes the extrusion plate 64 to slide toward one end, so that the extrusion plate 64 squeezes the air inside the support tube 62 to the circulation groove 68, so as to fill it into the first airbag circle 58, thereby expanding the first airbag circle 58; It should be particularly noted that one end of the first cylinder 41, the second cylinder 43, the third cylinder 45 and the fourth cylinder 47 are all provided with a connecting device 6, and the first cylinder 41, the second cylinder 43, the third cylinder 45 and the fourth cylinder 47 are respectively connected to the first disc 51, the second disc 53, the third disc 55 and the fourth cylinder 47 through the four connecting devices 6, so that the air is squeezed to the second airbag ring 59 through the connecting device 6 at one end of the second cylinder 43, so that the first airbag ring 58 and the second airbag ring 59 are expanded, and when the piston disc 67 pushes the squeezing disc 64 to slide to the limit, the piston disc 67 will contact the support cylinder 62, and the high-pressure air pushes the piston disc 67 and the support cylinder 62 to slide to one end, so that the support cylinder 62 drives the adjustment device 5 to slide to one end; At this time, the first airbag ring 58 and the second airbag ring 59 at the first clamping groove 52 and the third clamping groove 56 are expanded, and the first airbag ring 58 and the second airbag ring 59 are expanded to contact the first layer tube and the second layer tube. Since the diameter of the first disc 51 is adapted to the inner wall of the mold 3, the first airbag ring 58 and the second airbag ring 59 at the first clamping groove 52 are in a sealed state, and the first airbag ring 58 and the second airbag ring 59 at the third clamping groove 56 are in a sealed state, so that the first disc 51, the second disc 53, the third disc 55 and the fourth disc 57 become pistons. Then, by pushing the first disc 51, the second disc 53, the third disc 55 and the fourth disc 57 to slide to one end, the first disc 51, the second disc 53, the third disc 55 and the fourth disc 57 are used to extract the air at the first circular groove 42 and the third circular groove 46, and transmit the cold air from the jet groove 48, so that the cold air ejected from the jet groove 48 flows to the third circular groove 46 and The first circular groove 42 is used to dry the outer surface and inner wall of the first layer of tubes and the second layer of tubes at the third circular groove 46 and the first circular groove 42, so that the outer surface and inner wall of the first layer of tubes and the second layer of tubes become hard and change from a liquid flexible state to a surface rigid state. Then, after the cold air absorbs the heat of the first layer of tubes and the second layer of tubes, it is reset by the reverse sliding adjustment device 5, so that the adjustment device 5 squeezes the air at the third circular groove 46 and the first circular groove 42 and discharges it from the air suction groove 49, and repeats the process over and over again, so that the outer surface and inner wall of the first layer of tubes and the second layer of tubes become hard quickly, so that it is convenient for the subsequent protective net to be stably set between the first layer of tubes and the second layer of tubes, and the protective net will not be embedded in the first layer of tubes or the second layer of tubes too much or too little, so that the protective net can be stably set between the first layer of tubes and the second layer of tubes, thereby improving the impact resistance of the PE water supply pipe, so as to ensure that the protective layer will not be damaged after the PE water supply pipe is impacted by external force or when the PE water supply pipe is connected by welding; It should be particularly noted that when the piston disc 67 slides to the air relief groove, the high-pressure air in the piston groove 61 will release pressure through the air relief groove, thereby driving the adjustment device 5 and the support cylinder 62 to reset through the first reset spring 63, and then the pressure accumulation groove 10 continues to accumulate pressure. When the pressure is higher than the pressure relief groove 11, the high pressure in the pressure accumulation groove 10 is released again through the pressure relief groove 11 to push the piston disc 67 and the support cylinder 62 to slide, thereby achieving the reciprocating sliding of the support cylinder 62. Example 3

[0029] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-5 A flow groove 77 is provided at the lower end of the circular shaft groove 76, and the flow groove 77 is connected to the extrusion chamber 72. A heating pipe 78 is installed inside the flow groove 77, and an overflow hole 79 is provided between the flow groove 77 and the extrusion chamber 72; A square groove 80 is provided on one side of the extrusion cavity 72. The square groove 80 is connected to the extrusion cavity 72. The size of the square groove 80 is larger than the size of the extrusion cavity 72. A push plate 81 is slidably connected inside the square groove 80. The size of the push plate 81 is adapted to the size of the extrusion cavity 72. A rack column 83 is also installed at one end of the first circular groove 42, and the rack column 83 passes through the separation device 4. A gear is installed on one side of the short shaft 74, and the rack column 83 meshes with the gear; A square column 85 is installed at one end of the rack column 83, and one end of the square column 85 is slidably connected to the inside of the extrusion chamber 72. A spring sheet 82 is also installed inside the extrusion chamber 72. The push plate 81 is used to abut against the spring sheet 82. A shaft rod 84 is installed at one end of the push plate 81, and one end of the shaft rod 84 is slidably connected to the inside of the square column 85. The shaft rod 84 and the square column 85 are connected via a third return spring 86. The first rod 12 is slidably connected inside the air-injection groove 48, the first spring 15 is installed on the upper end of the first rod 12, the first sealing plate 13 is installed on the lower end of the first rod 12, and the first annular disk 14 is also installed inside the air-injection groove 48, and the first sealing plate 13 is used to abut against the first annular disk 14; A second rod 16 is slidably connected inside the suction groove 49 , a second spring 19 is installed on the upper end of the second rod 16 , a second sealing plate 17 is installed on the lower end of the second rod 16 , and a second annular disk 18 is also installed inside the suction groove 49 , and the second sealing plate 17 is used to abut against the second annular disk 18 .

[0030] according to Figure 4 As shown, since the protective layer and the first and second pipe layers are made of different materials, when the three are combined, gaps will appear between the protective layer and the first and second pipe layers, which may cause stratification after the first and second pipe layers solidify, making the PE water pipe unusable. Therefore, a scraping device 7 is installed at the second disc 53 and the fourth disc 57, and a colloid is sprayed through the spraying slot 73 of the scraping device 7 to the gap between the first and second pipe layers and the protective layer, so that the colloid is used to eliminate the gap between the first and second pipe layers and the protective layer, thereby improving the connection strength between the first and second pipe layers and the protective layer and reducing the occurrence of stratification. The colloid is the raw material liquid of the first layer tube and the raw material liquid of the second layer tube; Further, according to Figure 4As shown, when the adjustment device 5 slides to one end, the gear meshes with the rack column 83, so that the gear rotates, the gear drives the short shaft 74 to rotate, and the short shaft 74 drives the scraper 75 to rotate. Since the upper end of the circular shaft groove 76 is connected with the first clamping groove 52, the scraper 75 of the scraper device 7 at the second disc 53 scrapes the inner wall of the first layer of the tube to form a first pit, and the scraper 75 of the scraper device 7 at the fourth disc 57 scrapes the outer wall of the second layer of the tube to form a second pit, and then the colloid is sprayed through the spraying slot 73, so that the colloid fills the gap between the first layer of the tube and the second layer of the tube and the first pit and the second pit, thereby further improving the connection strength of the first layer of the tube, the second layer of the tube and the protective layer; Furthermore, the waste scraped by the scraper 75 will fall into the flow groove 77 through the circular shaft groove 76, and the waste will be heated by the heating tube 78 to become liquid and flow to the extrusion chamber 72 through the overflow hole 79. When the adjustment device 5 slides to the other end and resets, the push plate 81 will be slidably connected to the extrusion chamber 72, so that the push plate 81 is used to squeeze the liquid inside the extrusion chamber 72 to the injection groove 73, and the liquid is sprayed to the gap between the first layer pipe and the second layer pipe through the injection groove 73; It should be noted that the second hose 71 penetrates the separation device 4 and the extrusion cylinder 2 so as to allow the raw material liquid to be transmitted to the extrusion chamber 72. The second hose 71 is ductile so as to adapt to the sliding of the adjustment device 5. according to Figure 5 As shown, the inside of the air injection slot 48 and the air suction slot 49 are both provided with a one-way valve, and the two one-way valves open in opposite directions; The one-way valve at the jet groove 48 includes a first rod 12 slidably connected inside the jet groove 48, a first spring 15 is installed on the upper end of the first rod 12, a first sealing plate 13 is installed on the lower end of the first rod 12, and a first annular disk 14 is also installed inside the jet groove 48, and the first sealing plate 13 is used to abut against the first annular disk 14; The one-way valve at the suction groove 49 includes a second rod 16 slidably connected inside the suction groove 49, a second spring 19 is installed on the upper end of the second rod 16, a second sealing plate 17 is installed on the lower end of the second rod 16, and a second annular disk 18 is also installed inside the suction groove 49, and the second sealing plate 17 is used to abut against the second annular disk 18.
