[0020] Please refer to the attached Figure 1 - attached Figure 10, an embodiment of the present invention provides an integrated device for the collaborative mixing of multiple raw materials of polyethylene resin and temperature-controlled granulation, including a stirring tank 1.

At the same time, the twin-screw extruder 9 can mix materials when extruding materials. At the same time, a rotating blade is arranged on the side of the twin-screw extruder 9 away from the motor 3. The rotating blade is closely attached to the die head template, directly cutting the just-extruded round plastic strip into pellets, realizing precise control of the temperature in multiple sections of the reaction area. In this way, according to the requirements of polyethylene resin in different reaction stages, a suitable temperature environment can be provided, which is beneficial to the melting and homogenization process of polymer materials, and reduces the problems of uneven molecular weight distribution or uneven material composition distribution caused by "hot spots" generated due to too high local temperature. Both sides of the outside of the stirring tank 1 are fixedly connected with support plates 8, and the bottom of the support plates 8 is fixedly connected to the top of the stirring tank 1. An electric flow regulating valve 12 is fixedly connected to the bottom of the stirring tank 1. A material tank 10 is arranged outside the stirring tank 1. A jacket is arranged outside the material tank 10, and a heat exchanger is fixedly connected. The waste heat of the jacket of the material tank 10 preheats the raw materials through the heat exchanger. A feeding pipe 13 is fixedly connected to the top of the stirring tank 1, and materials are injected through the feeding pipe 13. A sealing cover is threadedly connected to the top of the feeding pipe 13.

[0021] The cyclic stirring mechanism 5 includes a fixed ring 501 which provides an installation position. The bottom of the fixed ring 501 is fixedly connected to the top of the stirring tank 1. Inside the fixed ring 501, there is a fixedly connected rotating gear ring 502. At the top of the stirring tank 1, there is a fixedly connected fixed curved rod 503. On one side of the fixed curved rod 503 away from the stirring tank 1, there is a rotatably connected driving gear 504. The fixed curved rod 503 can mount the driving gear 504. Outside the rotating shaft 4, there is a fixedly connected driving gear 505. The rotation of the driving gear 505 can drive the driving gear 504 to rotate and drive the rotating gear ring 502 to rotate through the driving gear 504. At this time, the rotation directions of the driving gear 505 and the rotating gear ring 502 are opposite. At the bottom of the rotating gear ring 502, there is a fixedly connected outer spiral stirring blade 506. The rotation of the outer spiral stirring blade 506 can push the material from top to bottom. At the top end of the outer wall of the outer spiral stirring blade 506, there are a plurality of discharge ports 507. At the bottom of the rotating shaft 4, there is a fixedly connected inner spiral stirring blade 508. The inner spiral stirring blade 508 can push the material from bottom to top, realizing the cyclic stirring of the material. The connection between the outside of the driving gear 504 and the driving gear 505 is meshing connection. The connection between the outside of the driving gear 504 and the inner side of the rotating gear ring 502 is meshing connection. The outer spiral stirring blade 506 is rotatably connected to the top of the stirring tank 1. The inner spiral stirring blade 508 is arranged inside the outer spiral stirring blade 506. At the bottom end of the outside of the outer spiral stirring blade 506, there is a rotatably connected stabilizing frame 11. The stabilizing frame 11 can maintain the rotational stability of the outer spiral stirring blade 506. The outer circumference of the stabilizing frame 11 is fixedly connected to the inner bottom end of the stirring tank 1. When mixing raw materials, start the motor 3. The output end of the motor 3 drives the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it can drive the driving gear 505 to rotate. When the driving gear 505 rotates, it can drive the driving gear 504 to rotate. After the driving gear 504 rotates, it can drive the rotating gear ring 502 to rotate, and the rotation direction is opposite to that of the driving gear 505. When the rotating gear ring 502 rotates, it can drive the outer spiral stirring blade 506 to rotate. When the rotating shaft 4 rotates, the inner spiral stirring blade 508 rotates, and the rotation directions of the inner spiral stirring blade 508 and the outer spiral stirring blade 506 are opposite. The rotation of the outer spiral stirring blade 506 can push the material from top to bottom. The inner spiral stirring blade 508 can push the material from bottom to top and discharge the material from the inside of the discharge port 507 into the inside of the stirring tank 1, thereby forming a cyclic stirring, and thus making the material mixing more uniform.

[0022] The dredging mechanism 6 includes an installation groove 601 which provides an installation position. The installation groove 601 is opened inside the inner spiral stirring blade 508. A return spring 602 is arranged inside the installation groove 601. A sliding limit column 603 is slidably connected inside the installation groove 601. The sliding limit column 603 has a limiting function. A dredging rod 604 is fixedly connected to the bottom of the sliding limit column 603. The up and down movement of the dredging rod 604 can play a role in dredging. A sliding groove 605 is opened inside the dredging rod 604. A driving column 606 is fixedly connected to the outside of the sliding limit column 603. A spiral groove 607 is opened inside the inner spiral stirring blade 508. The rotation of the spiral groove 607 can drive the driving column 606 to move up and down, and then can drive the sliding limit column 603 and the dredging rod 604 to move up and down. A limiting rod 608 is slidably connected inside the sliding groove 605. The sliding of the limiting rod 608 inside the sliding groove 605 can limit the movement track of the dredging rod 604, so that the dredging rod 604 can only move up and down and cannot rotate. The limiting rod 608 is fixedly connected to the inner bottom end of the mixing tank 1. One end of the return spring 602 is fixedly connected to the inner top end of the installation groove 601, and the other end of the return spring 602 is fixedly connected to the inside of the sliding limit column 603. The dredging rod 604 penetrates through the bottom of the inner spiral stirring blade 508. The driving column 606 is slidably connected inside the spiral groove 607. When discharging materials, the support frame 2 is also started at this time. Since the inner spiral stirring blade 508 rotates, the spiral groove 607 inside the inner spiral stirring blade 508 can rotate. And because the driving column 606 is arranged inside the spiral groove 607 and due to the limitation of the limiting rod 608, the dredging rod 604 can only move up and down and cannot rotate following the inner spiral stirring blade 508. Therefore, as the inner spiral stirring blade 508 rotates, the spiral groove 607 can rotate, and then can drive the driving column 606 to move upward inside the spiral groove 607, and then can drive the sliding limit column 603 to move upward. Therefore, the sliding groove 605 can be driven to move upward. When the driving column 606 moves upward to the vertical groove, under the thrust of the return spring 602, the sliding limit column 603 is reset, and then the driving column 606 can move back to the bottom of the spiral groove 607 again. Therefore, the up and down reciprocating movement of the sliding limit column 603 is realized, and then the bottom of the mixing tank 1 can be dredged by using the dredging rod 604 to prevent material blockage.

[0023] The anti - adhesion mechanism 7 includes two mounting boxes 701. The mounting boxes 701 provide mounting positions. Inside the mounting boxes 701, there are multiple pressing springs 702. A limiting plate 703 is slidably connected inside the mounting boxes 701. The limiting plate 703 has a limiting function. One end of the limiting plate 703 away from the pressing spring 702 is fixedly connected to a scraping plate 704. The pressing spring 702 can use its own reaction force to give the limiting plate 703 a force towards the outside, so that the scraping plate 704 can closely adhere to the inner wall of the mixing tank 1. The scraping plate 704 can scrape off the raw materials adhering to the inner wall of the mixing tank 1, avoiding waste of raw materials. On one side of the mounting box 701 away from the scraping plate 704, multiple connecting columns 705 are fixedly connected. The connecting columns 705 have a connecting function. One side of the multiple connecting columns 705 away from the mounting box 701 is respectively fixedly connected to the outer sides of the outer spiral stirring blades 506. One end of the pressing spring 702 is fixedly connected inside the mounting box 701, and the other end of the pressing spring 702 is fixedly connected to the side of the limiting plate 703 away from the scraping plate 704. As the outer spiral stirring blades 506 rotate, they can drive the connecting columns 705 to rotate. When the connecting columns 705 rotate, they can drive the mounting boxes 701 to rotate. When the mounting boxes 701 rotate, they can drive the limiting plates 703 and the scraping plates 704 to rotate, and then scrape off the raw materials adhering to the inner wall of the mixing tank 1, preventing waste of raw materials.

[0024] Working principle: When mixing raw materials, start the motor 3. The output end of the motor 3 drives the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it can drive the driving gear 505 to rotate. When the driving gear 505 rotates, it can drive the driven gear 504 to rotate. After the driven gear 504 rotates, it can drive the rotating gear ring 502 to rotate, and the rotation direction is opposite to that of the driving gear 505. When the rotating gear ring 502 rotates, it can drive the outer spiral stirring blades 506 to rotate. When the rotating shaft 4 rotates, the inner spiral stirring blades 508 rotate, and the rotation direction of the inner spiral stirring blades 508 is opposite to that of the outer spiral stirring blades 506. The rotation of the outer spiral stirring blades 506 can push the materials from top to bottom, while the inner spiral stirring blades 508 can push the materials from bottom to top and discharge the materials from the inside of the discharge port 507 into the mixing tank 1, thus forming a circulating stirring, and making the materials mixed more evenly. When discharging, the support frame 2 is also started. At this time, since the inner spiral stirring blade 508 rotates, the spiral groove 607 inside the inner spiral stirring blade 508 can be rotated. And because the driving column 606 is arranged inside the spiral groove 607, and due to the limitation of the limiting rod 608, the dredging rod 604 can only move up and down and cannot rotate with the inner spiral stirring blade 508. Therefore, as the inner spiral stirring blade 508 rotates, the spiral groove 607 can be rotated, and then the driving column 606 can be driven to move upward inside the spiral groove 607, and then the sliding limiting column 603 can be driven to move upward. Therefore, the sliding groove 605 can be driven to move upward. When the driving column 606 moves upward to the vertical groove, under the thrust of the return spring 602, the sliding limiting column 603 is reset, and then the driving column 606 can be driven to move back to the bottom of the spiral groove 607. Therefore, the up-and-down reciprocating motion of the sliding limiting column 603 is realized, and then the bottom of the mixing tank 1 can be dredged by using the dredging rod 604 to prevent material blockage. As the outer spiral stirring blade 506 rotates, the connecting column 705 can be driven to rotate. When the connecting column 705 rotates, the mounting box 701 can be driven to rotate. When the mounting box 701 rotates, the mounting box 701 can be driven to rotate, thereby driving the limiting plate 703 and the scraping plate 704 to rotate. Then, the raw materials attached to the inner wall of the mixing tank 1 can be scraped off to prevent waste of raw materials.
