Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Specific examples are given below.

[0027] See also Figure 1-Figure 5 The utility model provides a polyethylene particle stirring device, comprising a stirring barrel 1, a fixing frame 2 is fixed to the outer side of the lower end of the stirring barrel 1; a cover plate 12 is detachably connected to the top of the stirring barrel 1; a fixing cylinder 3 is fixed to the top of the cover plate 12; a stirring assembly is arranged on the inner side of the stirring barrel 1; a discharge port 5 is fixed to the lower end of the stirring barrel 1; a feed port 4 is fixed to the top of one side of the stirring barrel 1;

[0028] The stirring assembly includes a driving motor 11; the driving motor 11 is arranged at the inner position of the top end of the fixed cylinder 3; the driving motor 11 is fixedly connected to the fixed cylinder 3; a rotating shaft 7 is fixed to the output end of the driving motor 11; the rotating shaft 7 extends to the inner side of the stirring barrel 1; a hollow rotating shaft 6 is sleeved on the outer side of the rotating shaft 7; the rotating shaft 7 is rotatably connected to the hollow rotating shaft 6; the lower end of the hollow rotating shaft 6 extends to the inner side of the stirring barrel 1; the hollow rotating shaft 6 is rotatably connected to the stirring barrel 1; a plurality of first stirring rollers 8 are evenly fixed to one end of the rotating shaft 7 extending to the outer side of the hollow rotating shaft 6; a plurality of second stirring rollers 9 are evenly fixed to the outer side of the hollow rotating shaft 6 located on the inner side of the stirring barrel 1; a driving assembly is arranged at a position inside the fixed cylinder 3 and corresponding to the hollow rotating shaft 6; a cleaning assembly is arranged on the side of the second stirring roller 9 away from the hollow rotating shaft 6. During operation, when stirring, the driving motor 11 is started; so that the driving motor 11 drives the rotating shaft 7 to rotate, and when the rotating shaft 7 rotates, the first stirring roller 8 stirs the raw materials inside the stirring barrel 1 clockwise, and when the rotating shaft 7 rotates, the driving component drives the hollow rotating shaft 6 to rotate counterclockwise, so that when the hollow rotating shaft 6 rotates, the second stirring roller 9 is driven to stir counterclockwise. This step can effectively make the hollow rotating shaft 6 and the rotating shaft 7 rotate in opposite directions when the driving motor 11 rotates through the driving component, thereby driving the second stirring roller 9 and the rotating shaft 7 to stir in different directions respectively, thereby effectively improving the uniformity of mixing the raw materials inside the stirring barrel 1 when stirring, improving the mixing quality of the raw materials, and improving the practicality of the device;

[0029] Further, such as Figure 2 and Figure 3As shown, the driving assembly includes a transmission gear 10; the transmission gear 10 is arranged at the outer position of the hollow rotating shaft 6 located inside the fixed cylinder 3; the transmission gear 10 is fixedly connected to the hollow rotating shaft 6; a transmission shaft 14 is rotatably connected to the inside of the fixed cylinder 3; the two ends of the transmission shaft 14 are respectively rotatably connected to the fixed cylinder 3 and the cover plate 12; the rotating shaft 7 is transmission-connected to the transmission shaft 14 through a transmission belt 13; a driving gear 15 is fixed at the position of the transmission shaft 14 corresponding to the transmission gear 10; the driving gear 15 is meshed and connected with the transmission belt 13. During operation, when the driving motor 11 is started, the driving motor 11 drives the rotating shaft 7 to rotate, and when the rotating shaft 7 rotates, the transmission shaft 14 is driven to rotate through the transmission belt 13, and when the transmission shaft 14 rotates, it drives the driving gear 15 fixed thereto to rotate, so that when the driving gear 15 rotates, the hollow rotating shaft 6 is driven to rotate in the opposite direction through the transmission gear 10 meshing with it.

[0030] Further, such as Figure 4 and Figure 5 As shown, the cleaning component includes a scraper 16; the scraper 16 is arranged at a side of the second stirring roller 9 away from the hollow rotating shaft 6; a connecting slider 17 is fixed to the side of the scraper 16 close to the second stirring roller 9; a connecting groove 19 is provided at a position of the second stirring roller 9 corresponding to the connecting slider 17; the connecting slider 17 is slidably connected to the second stirring roller 9 through the connecting groove 19; a plug-in groove 18 is provided on one side of the top end of the rotating shaft 7; and a plug-in component is provided on the inner side of the second stirring roller 9 and at a position corresponding to the plug-in groove 18. During operation, when the second stirring roller 9 rotates with the hollow shaft 6 as the center, the scraper 16 rotates at the same time, so that the scraper 16 is in contact with the inner wall of the stirring barrel 1, so that the scraper 16 can scrape the inner wall of the stirring barrel 1 when it rotates. This step can ensure that when the raw materials are stirred, the scraper 16 can rotate to scrape the raw materials on the inner wall of the stirring barrel 1, so that the Wuxuan operator can clean the inner wall of the stirring barrel 1 through other tools, which effectively reduces the labor intensity of the workers, increases the service life of the device, and improves the practicality of the device.

[0031] like Figure 5As shown, the plug-in assembly includes a connecting rod 21; the connecting rod 21 is horizontally arranged on the inner side of the second stirring roller 9 at a position corresponding to the plug-in groove 18; the connecting rod 21 is slidably connected to the second stirring roller 9; a plug-in block 20 is fixed to one end of the connecting rod 21 close to the connecting slider 17; the plug-in block 20 is slidably connected to the second stirring roller 9; the plug-in block 20 is plug-connected to the connecting slider 17 through the plug-in groove 18. During operation, when the scraper 16 needs to be installed, first move the connecting slider 17 to the inner side of the second stirring roller 9 through the connecting slide groove 19. When the connecting slider 17 moves, it will squeeze the plug-in block 20, and the plug-in block 20 moves in the direction close to the connecting rod 21. When the connecting slider 17 moves to the position corresponding to the plug-in groove 18 and the plug-in block 20, the plug-in block 20 moves to the inner side of the plug-in groove 18, and the limiting of the connecting slider 17 can be completed.

During operation, when the plug-in block 20 approaches the connecting rod 21, the plug-in block 20 will squeeze the limit spring 22, causing the limit spring 22 to undergo elastic deformation. When the plug-in block 20 corresponds to the plug-in slot 18, the plug-in block 20 is pushed under the elastic action of the limit spring 22, so that the plug-in block 20 can be limited. This step can limit the plug-in block 20, thereby effectively preventing the plug-in block 20 from sliding randomly inside the second stirring roller 9, thereby improving the stability of the plug-in block 20.

During operation, when the scraper 16 needs to be disassembled, the lifting ball 23 is pulled so that the lifting ball 23 drives the connecting rod 21 to move, thereby driving the plug-in block 20 to move through the connecting rod 21. This step can facilitate the operator to operate and control the movement of the plug-in block 20, thereby improving the convenience of disassembling the scraper 16.

[0034] like Figure 2 and Figure 3As shown, the number of teeth of the transmission gear 10 is greater than the number of teeth of the driving gear 15. During operation, when the driving gear 15 rotates, it can slowly drive the transmission gear 10 to rotate, thereby ensuring that the number of rotations of the transmission gear 10 is less than the number of rotations of the driving gear 15, thereby achieving speed reduction. This step can reduce the rotation speed of the hollow shaft 6, thereby avoiding damage to the pressure of the second stirring roller 9 when the rotation speed is the same as that of the first stirring roller 8, thereby increasing the service life of the second stirring roller 9 and the first stirring roller 8.

[0035] Working principle: During operation, when stirring, the driving motor 11 is started; the driving motor 11 drives the rotating shaft 7 to rotate, and when the rotating shaft 7 rotates, the first stirring roller 8 stirs the raw materials inside the stirring barrel 1 clockwise, and when the rotating shaft 7 rotates, the driving component drives the hollow rotating shaft 6 to rotate counterclockwise, so that when the hollow rotating shaft 6 rotates, it drives the second stirring roller 9 to stir counterclockwise. This step can effectively make the driving component make the hollow rotating shaft 6 and the rotating shaft 7 rotate in opposite directions when the driving motor 11 rotates, thereby driving the second stirring roller 9 and the rotating shaft 7 to stir in different directions respectively, thereby effectively improving the stirring of the raw materials inside the stirring barrel 1 The uniformity of mixing during stirring improves the mixing quality of the raw materials and improves the practicality of the device. During operation, when the driving motor 11 is started, the driving motor 11 drives the rotating shaft 7 to rotate, and when the rotating shaft 7 rotates, the transmission shaft 14 is driven to rotate through the transmission belt 13. When the transmission shaft 14 rotates, it drives the driving gear 15 fixed thereto to rotate, so that when the driving gear 15 rotates, the hollow rotating shaft 6 is driven to rotate in the opposite direction through the transmission gear 10 meshing with it. This step can ensure that when the rotating shaft 7 rotates, the hollow rotating shaft 6 can be driven to rotate through the driving gear 15 and the transmission gear 10, thereby ensuring that the direction of the hollow rotating shaft 6 is opposite to that of the rotating shaft 7, thereby improving The stirring efficiency is improved; when working, when the second stirring roller 9 rotates with the hollow rotating shaft 6 as the center, the scraper 16 rotates at the same time, so that the scraper 16 is in contact with the inner wall of the stirring barrel 1, so that the scraper 16 can scrape the inner wall of the stirring barrel 1 when it rotates. This step can ensure that when the raw materials are stirred, the scraper 16 can be rotated to scrape the raw materials on the inner wall of the stirring barrel 1, so that the Wuxuan operator can clean the inner wall of the stirring barrel 1 through other tools, which effectively reduces the labor intensity of the workers, increases the service life of the device, and improves the practicality of the device; when working, when the scraper 16 needs to be installed, first Move the connecting slider 17 to the inner side of the second stirring roller 9 through the connecting slide groove 19. When the connecting slider 17 moves, it will squeeze the plug-in block 20, and the plug-in block 20 will move in the direction close to the connecting rod 21. When the connecting slider 17 moves to the position corresponding to the plug-in groove 18 and the plug-in block 20, the plug-in block 20 moves to the inner side of the plug-in groove 18, and the limiting of the connecting slider 17 can be completed. This step can effectively connect the plug-in block 20 with the connecting slider 17 through the plug-in connection, so that the plug-in block 20 can push the connecting slider 17, thereby effectively avoiding the situation that the connecting slider 17 slides out from the inner side of the second stirring roller 9, and improving the stability of the scraper 16.During operation, when the plug-in block 20 approaches the connecting rod 21, the plug-in block 20 will squeeze the limit spring 22, causing the limit spring 22 to undergo elastic deformation. When the plug-in block 20 corresponds to the plug-in slot 18, the plug-in block 20 is pushed under the elastic action of the limit spring 22, thereby limiting the plug-in block 20. This step can limit the plug-in block 20, thereby effectively preventing the plug-in block 20 from sliding freely on the inner side of the second stirring roller 9, thereby improving the stability of the plug-in block 20. During operation, when the scraper 16 needs to be disassembled, the lifting ball 23 is pulled so that the lifting ball 23 drives the connecting rod 21 to move. Thus, the plug-in block 20 can be driven to move by the connecting rod 21. This step can facilitate the operator to operate and control the movement of the plug-in block 20, and improve the convenience of disassembling the scraper 16; when working, when the driving gear 15 rotates, it can slowly drive the transmission gear 10 to rotate, so as to ensure that the number of rotations of the transmission gear 10 is less than the number of rotations of the driving gear 15, so as to achieve speed reduction. This step can reduce the rotation speed of the hollow shaft 6, so as to avoid the second stirring roller 9 and the first stirring roller 8 from causing damage to the pressure when the rotation speed is the same, thereby improving the service life of the second stirring roller 9 and the first stirring roller 8. ;
