By turning on the first drive motor 501, the first transmission rod 502 and multiple stirring blades 503 are driven to rotate simultaneously, thereby stirring the heated high polyethylene particles. At the same time, the small motor 504 is turned on to drive the first gear 505 to rotate. The first gear 505 rotates and engages with the second gear 506 outside the sleeve 507 for transmission. Finally, the scraper 508 outside the sleeve 507 stirs and scrapes the material on the inner wall of the inner tank 3. The sleeve 507 is movably mounted on the first transmission rod 502, so that the two will not interfere with each other during rotation, so that the two groups rotate at different frequencies, thereby improving the stirring efficiency.

[0029] like Figure 1 and Figure 2 As shown, a first electric heater 4 is provided between the melting stirring outer tank 1 and the inner tank 3. The first electric heater 4 is distributed at equal intervals in the melting stirring outer tank 1. Multiple first electric heaters 4 are provided between the melting stirring outer tank 1 and the inner tank 3, thereby heating and melting the polyethylene particles during the stirring process.

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the stirring mechanism 5 includes a first drive motor 501, which is installed above the melting and stirring outer tank 1. The output end of the first drive motor 501 is fixedly connected to the first transmission rod 502, and the outside of the first transmission rod 502 is fixedly connected to the stirring blade 503. By turning on the switch of the first drive motor 501, the first transmission rod 502 and the multiple stirring blades 503 are driven to rotate simultaneously, thereby stirring the heated high polyethylene particles and improving the melting efficiency.

[0031] like Figure 4 As shown, a small motor 504 is fixedly provided on the upper side of the melting and stirring outer tank 1, and the output end of the small motor 504 is fixedly connected to the first gear 505, and one side of the first gear 505 is movably connected to the second gear 506, and the interior of the second gear 506 is fixedly connected to the sleeve 507, and the two sides of the sleeve 507 are fixedly connected to the scrapers 508.

[0032] like Figure 2 、 Figure 3 and Figure 4As shown, the sleeve 507 is sleeved on the outside of the first transmission rod 502, the first transmission rod 502 is movably connected to the sleeve 507, and the sleeve 507 is movably sleeved on the first transmission rod 502, so that the two will not interfere with each other during rotation. In this way, the first transmission rod 502 drives the stirring blade 503 to rotate and the sleeve 507 drives the scraper 508 to rotate, thereby improving the overall stirring efficiency.

[0033] like Figure 1 and Figure 5 As shown, the conveying mechanism 7 includes a conveying cylinder 701, which is fixedly connected to the lower end of the connecting pipe 6, and a second driving motor 702 is fixedly provided on one side of the conveying cylinder 701.

A second electric heater 705 is provided on the outside of the conveying cylinder 701, and a discharge port 706 is provided on one side of the conveying cylinder 701. When the melted ethylene particles enter the conveying cylinder 701, the second driving motor 702 is used to drive the second transmission rod 703 and the external threaded blade 704 to rotate simultaneously, thereby conveying the melted ethylene particles. At the same time, during the conveying process, the second electric heater 705 on the outside of the conveying cylinder 701 can heat the particles again during the conveying process.

[0034] The working principle of the utility model is as follows: first, the external power supply is turned on, and then the polyethylene particles are poured from the feed hopper 2 into the melting and stirring outer tank 1 and the inner tank 3, and then the multiple first electric heating switches 4 between the melting and stirring outer tank 1 and the inner tank 3 are turned on to heat the polyethylene particles inside the inner tank 3, and then the first drive motor 501 switch is turned on to drive the first transmission rod 502 and the multiple stirring blades 503 to rotate at the same time, so as to stir the heated high polyethylene particles, and at the same time, the small motor 504 switch is turned on to drive the first gear 505 to rotate, and the first gear 505 rotates to engage with the second gear 506 outside the sleeve 507 for transmission, and finally the scraper 508 outside the sleeve 507 stirs and scrapes the material on the inner wall of the inner tank 3 to prevent the heated polyethylene from remaining on the inner wall of the inner tank 3, and the sleeve 507 is movably mounted on the first transmission rod 502, so that the two will not be interfered with during the rotation process. The two groups rotate at different frequencies, which improves the stirring efficiency. After the polyethylene particles are stirred and melted, the first drive motor 501, the small motor 504 and the first electric heater 4 are turned off, and then the valve outside the connecting pipe 6 is opened to allow the molten polyethylene inside the inner liner 3 to flow from the connecting pipe 6 into the conveying cylinder 701. Then, the second drive motor 702 is turned on to drive the second transmission rod 703 and the external threaded blades 704 to rotate, thereby conveying the molten polyethylene. During the conveying process, the second electric heater 705 outside the conveying cylinder 701 is turned on to heat it again, thereby keeping the polyethylene in a molten state. Finally, the polyethylene is discharged from the discharge port 706 through the threaded blades 704. Finally, when the conveying is completed, the second drive motor 702 and the second electric heater 705 are turned off, and finally the external power supply is cut off. In this way, the use process of the polyethylene particle melting device is completed.
