They have excellent characteristics of resisting most chemicals used in life and industry. Polyethylene pipeline fusion welding is an important method for connecting two polyethylene pipelines. This welding method usually requires the use of professional hot melt welding machines to ensure correct temperature, pressure, and time control to guarantee the welding quality.

Through the setting of the preheating and softening mechanism 7, the welding ends of the two polyethylene pipes can be preheated to gradually soften them, thereby improving the efficiency when the two ends of the polyethylene pipes are welded. Moreover, the preheating and softening mechanism 7 mainly heats the inner wall and outer wall of the polyethylene pipe simultaneously, which can improve the heating efficiency, ensure uniform heating, further save time costs, and improve work efficiency.

[0029] According to Figure 1 、 Figure 2 、 Figure 3 and Figure 9 As shown in Figure 1 , Figure 2 , Figure 3 and Figure 9 , the accelerated cooling mechanism 9 includes an air suction fan 901, which is fixedly mounted on the top of the equipment body 1.

Through the setting of the accelerated cooling mechanism 9, fresh air can be blown to the welding part of the two polyethylene pipes, thereby improving its cooling and forming speed, reducing the equipment shutdown time, and further improving work efficiency.

[0030] According to Figure 1 、 Figure 2 、 Figure 3 、 Figure 10 and Figure 11 As shown in Figure 1 , Figure 2 , Figure 3 , Figure 10 and Figure 11 , the filtering and purifying mechanism 10 includes a filtering box 1001, which is fixedly mounted on the top of the equipment body 1. An air inlet pipe 1002 is connected to one side of the filtering box 1001, and one end of the air inlet pipe 1002 is connected to the equipment body 1.

Through the setting of the filtering and purifying mechanism 10, the smoke and carbon dioxide generated during welding can be filtered and purified to prevent them from escaping and causing large-scale air pollution, thereby ensuring air quality.

[0031] According to Figure 1 、 Figure 2 、 Figure 3 、 Figure 10 and Figure 12As shown in the figure, the spray cooling mechanism 11 includes a protective frame 1101. Inside the protective frame 1101, a water pump 1102 is installed.

Through the setting of the spray cooling mechanism 11, the smoke and carbon dioxide generated during welding can be spray-cooled to prevent the temperature in the working area from rising and ensure the stability of the working environment temperature.

[0032] According to Figure 1 and Figure 3 As shown in the figure, an observation window 12 is provided on the surface of the equipment body 1. Feeding and discharging ports 13 are respectively provided through both sides of the equipment body 1. Through the setting of the observation window 12, the welding progress of the equipment body 1 can be observed. Through the setting of the feeding and discharging ports 13, it is convenient to carry out feeding and discharging operations, thereby reducing the operation difficulty of the equipment and saving labor and time costs.

[0033] According to Figure 1 and Figure 2 As shown in the figure, two hinges 14 are symmetrically provided on both sides of the equipment body 1. One end of each two hinges 14 is fixedly connected to a hatch 15. A handle 16 is installed on one side of each hatch 15. Each hatch 15 is respectively adapted to a corresponding feeding and discharging port 13. Through the setting of the hatch 15, dust can be effectively prevented from entering the interior of the equipment body 1, thereby reducing the cleaning difficulty, ensuring that the internal structure is not damaged by dust, and prolonging the service life of the equipment.

[0034] According to Figure 1 、 Figure 2 and Figure 3 As shown in the figure, feet 17 are provided at the four corners of the bottom of the equipment body 1. Anti-slip pads 18 are provided at the bottom of each foot 17. Through the setting of the feet 17, stable support can be provided for the equipment body 1. At the same time, in cooperation with the anti-slip pads 18, the friction with the ground is increased to prevent the equipment body 1 from shaking during use and improve the stability of the equipment.

[0035] According to Figure 3 、 Figure 4 、 Figure 6 and Figure 8 As shown in the figure, the inner diameters of one ends of the lower half welding ring 802 and the upper half welding ring 806 gradually decrease from the outside to the inside. Through the distinction of the inner diameters, a single-section polyethylene pipe can be softened and inserted into the other polyethylene pipe, thereby ensuring more sufficient welding and higher welding precision.

[0036] Working principle: First, transport the device body 1 to the designated working area. The tripod 17 cooperates with the anti-slip pad 18 to contact the ground, providing stable support for the device body 1. Then, connect the power supply to the internal electrical structure of the device body 1 through an external wire, and at the same time connect the external water source to the external pipeline 1103 to supply power and water to the device.

[0037] Feeding stage: Manually pull two handles 16 by hand, so that the corresponding hinges 14 are stressed and rotated, driving the bin door 15 to open. Then, put two polyethylene pipes into the device body 1 respectively from one corresponding feeding and discharging port 13 for feeding.

[0038] Docking stage: Start the servo motor 307 to drive the lead screw 308 to rotate, prompting the two clamping brackets 306 to slide on the lead screw 308 and the two guide rods 305 to clamp the polyethylene pipe. Then, start two first servo cylinders 302 to drive the corresponding first sliders 303 to drive the first adjustment seat 304 to slide, making the welding ends of the two polyethylene pipes gradually approach.

[0039] Preheating stage: Start the second servo cylinder 4 to drive the second slider 5 to drive the second adjustment seat 6 to slide, so that the preheating and softening mechanism 7 moves to the same central axis as the two polyethylene pipes. Then, the two first servo cylinders 302 push the corresponding welding ends of the polyethylene pipes into the preheating and softening mechanism 7. Start the preheating and softening mechanism 7, and heat the polyethylene pipe from the inside by the heating rod 703 and from the outer wall by the heating wire 704, making the welding ends of the two polyethylene pipes gradually soften.

[0040] Welding stage: When the welding ends of the two polyethylene pipes are softened, the corresponding first servo cylinder 302 pulls them out of the preheating and softening mechanism 7. At this time, start the second servo cylinder 4 again to drive the second slider 5 to drive the second adjustment seat 6 to slide, so that the heating and welding mechanism 8 moves to the same central axis as the two polyethylene pipes. Then, the two first servo cylinders 302 push the corresponding pipes into the heating and welding mechanism 8 together. Start the heating and welding mechanism 8, and make the lower welding ring 802 cooperate with the upper welding ring 806 to weld the two polyethylene pipes.

[0041] Exhaust gas cooling and purification stage: Start the axial flow fan 1003 to inhale the smoke and carbon dioxide generated by welding into the filter box 1001 through the intake pipe 1002, and start the water pump 1102 to inhale the external water source connected to the external pipeline 1103, and transport it to the second shunt pipe 1105 through the delivery pipe 1104. The water is atomized and sprayed by the atomizing nozzle 1106 to cool the smoke and carbon dioxide. At the same time, the smoke and carbon dioxide pass through the activated carbon filter plate 1004 to filter and purify the impurities and harmful molecules in them, and the sprayed waste water is discharged outward through the drain pipe 1005.

[0042] In the cooling and forming stage, after the fusion welding of two polyethylene pipes is completed, the third servo cylinder 804 is started to drive the connecting frame 805 to drive the upper half fusion welding ring 806 to separate from the lower half fusion welding ring 802. At this time, the suction fan 901 is started to suck in external fresh air, which is then transported through the connecting pipe 903 to the first shunt pipe 904, and the fresh air is sprayed by the fresh air nozzle 905 onto the fusion welding part of the two polyethylene pipes to accelerate its cooling and forming speed.

[0043] In the discharging stage, after the polyethylene pipe is fusion welded and cooled and formed, the two servo motors 307 are started again to drive the corresponding lead screws 308 to rotate, so that the clamping frame 306 releases the clamping of the polyethylene pipe. At this time, the formed polyethylene pipe is manually taken out of the equipment body 1 from the single inlet and outlet 13.

[0044] According to the above-described method, the heating and fusion welding of the polyethylene pipe and the complete use of the equipment can be completed.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
