[0030] When the above scheme is put into actual use, different plastic particle raw materials that need to be mixed are added into the cylinder 3 through the feed barrel 2, the stirring motor 1 is started to drive the stirring shaft 23 to rotate, and the plastic particles are stirred and mixed by the stirring paddle 15. After the mixing is completed, the stirring motor 1 is stopped, and the mixed plastic particles are discharged from the cylinder 3 through the discharge port 19. After the completion, the scraper and slag removal component is started to clean the inside of the cylinder 3, and the particle waste attached to the inner wall of the cylinder 3 is cleaned off from the inner wall of the cylinder 3 and discharged. The advantage of this is that the scraper and slag removal component can be used to clean the inner wall of the cylinder 3 in multiple directions, and on the basis of rotating to clean the inner wall of the cylinder 3, the direction of the inner wall of the cylinder 3 can be adjusted at multiple angles to clean the inner wall of the cylinder 3, which can effectively ensure the cleaning effect of the cylinder 3.

[0031] As a further solution of the present invention, the scraping and slag removal assembly includes a sleeve rod 13, which is slidably sleeved on the outside of the stirring shaft 23, and a plurality of slide grooves 14 corresponding to the stirring paddles 15 are opened on the sleeve rod 13. A bottom plate 18 is provided at the bottom of the cylinder 3, and a fixed sleeve 16 is fixedly connected to the top of the bottom plate 18. The bottom of the sleeve rod 13 slides through the fixed sleeve 16, and a transmission gear cylinder 31 is fixedly connected to the bottom of the sleeve rod 13. A docking gear cylinder 24 that can mesh with the transmission gear cylinder 31 is fixedly connected to the top of the bottom plate 18. Connecting rods 21 are fixedly connected to both sides of the top of the bottom plate 18, and a first scraper 25 is provided on the connecting rod 21. A sliding plate 20 is slidably connected to the connecting rod 21, and a second scraper 27 is fixedly connected to the side wall of the sliding plate 20. A threaded rod 22 is rotatably connected to the top of the bottom plate 18, and the sliding plate 20 is spirally sleeved on the threaded rod 22 outside, the upper cover plate 7 is rotatably connected with a sealing plate 6 outside, the top of the threaded rod 22 passes through the sealing plate 6 and is arranged above the upper cover plate 7, the top of the cylinder 3 is fixedly connected with a plurality of outer racks 4 distributed in an annular manner, the top of the upper cover plate 7 is fixedly connected with a plurality of inner racks 5 distributed in an annular manner, the threaded rod 22 is fixedly connected with a transmission gear 8 that can mesh with the outer rack 4 and the inner rack 5 respectively, the top of the upper cover plate 7 is fixedly connected with a fixing frame 9, the stirring motor 1 is fixedly sleeved on the top of the fixing frame 9, the top of the sleeve rod 13 passes through the upper cover plate 7 and is arranged above the upper cover plate 7, the top of the sleeve rod 13 is fixedly connected with a connecting plate 10, the bottom of the connecting plate 10 is fixedly connected with a reset spring 11 for its reset, the top of the upper cover plate 7 is fixedly connected with a push cylinder 12, and the output end of the push cylinder 12 is fixedly connected to the top of the sleeve rod 13;

[0032] When the above scheme is put into practical use, after the mixing is completed and the inside of the cylinder 3 is cleaned, the push cylinder 12 is started to push the sleeve rod 13 to slide downward on the stirring shaft 23, so that the reset spring 11 is compressed, and the transmission gear cylinder 31 at the bottom of the sleeve rod 13 slowly contacts and meshes with the docking gear cylinder 24, and then the stirring motor 1 is started to drive the stirring shaft 23 to rotate. At this time, the stirring motor 1 rotates and drives the bottom plate 18 to rotate together through the transmission gear cylinder 31, and the bottom plate 18 will drive the connecting rod 21 to rotate, and the first scraper 25 on the side wall of the connecting rod 21 contacts the inner wall of the cylinder 3 to clean the plastic debris attached to the inner wall of the cylinder 3. At the same time, when the bottom plate 18 rotates, the transmission gear 8 will rotate together with the threaded rod 22 on the bottom plate 18. When the transmission gear 8 rotates to a position meshing with the outer rack 4, the transmission gear 8 will drive the threaded rod 22 to rotate together, so that the sliding plate 2 The inner wall of the cylinder 3 is cleaned by the second scraper 27 sliding downward along the threaded rod 22. When the transmission gear 8 rotates to the position where it is out of contact with the outer rack 4, the bottom plate 18 continues to rotate so that the transmission gear 8 continues to mesh with the inner rack 5. The inner rack 5 drives the transmission gear 8 to rotate in the opposite direction to the direction when the outer rack 4 drives the transmission gear 8 to rotate, so that the threaded rod 22 reverses the sliding plate 20 and slides upward along the threaded rod 22, thereby resetting the sliding plate 20 upward and changing the sliding direction of the second scraper 27 to clean the inner wall of the stirring motor 1 again. The advantage of this is that the inner wall of the cylinder 3 is cleaned by the threaded rod 22 rotating in the horizontal direction, and the inner wall of the cylinder 3 is cleaned in the vertical direction by the second scraper 27 sliding up and down, which can further improve the cleaning effect of the inner wall of the cylinder 3.

[0033] As a further solution of the present invention, a transmission frame 30 is slidably connected inside the bottom plate 18, one end of the transmission frame 30 is fixedly connected to a protrusion 29, the top of the protrusion 29 is arranged above the bottom plate 18, and the bottom end of the transmission gear cylinder 31 is fixedly connected to a push block for contacting the protrusion 29, the first scraper 25 is slidably arranged inside the connecting rod 21, one end of the first scraper 25 passes through the connecting rod 21 and is arranged on the outside of the connecting rod 21, and the outer walls of the connecting rod 21 on both sides of the first scraper 25 are respectively fixedly connected with connecting strips 26, and the connecting strip 26 is slidably connected to a sliding block 28 having one end in contact with the first scraper 25, and a strong spring for resetting the sliding block 28 is arranged on the sliding block 28;

[0034] When the above scheme is put into practical use, when the sleeve rod 13 slides downward and engages with the docking gear cylinder 24, the push block at the bottom of the transmission gear cylinder 31 will first contact the protrusion 29, and as the sleeve rod 13 slides downward, the protrusion 29 is gradually pushed to slide, and the protrusion 29 pushes the first scraper 25 to slide through the transmission frame 30, so that the first scraper 25 pushes the closed compression spring of the sliding block 28, so that the first scraper 25 extends to the outside of the connecting rod 21, until the transmission gear cylinder 31 slides to the position of engaging with the docking gear cylinder 24, and the first scraper 25 is fully extended to the cylinder body 3, the inner wall of the cylinder body 3 can be cleaned. After the cleaning is completed, the sleeve rod 13 slides upward to reset. After being separated from the extrusion of the push block, the first scraper 25 is squeezed to retract into the inside of the connecting rod 21 under the action of the reset elastic force of the strong spring on the sliding block 28. At the same time, the sliding block 28 will remove the slag on the surface of the first scraper 25 during the squeezing of the first scraper 25, and clean up the debris attached to the surface of the first scraper 25, which can effectively reduce the attachment of the debris on the first scraper 25 and improve the cleaning effect of the first scraper 25 on the cylinder body 3.

[0035] As a further solution of the present invention, a cone plate 17 is fixedly connected to the top of the bottom plate 18, and the two side walls of the top of the cone plate 17 are inclined walls;

[0036] When the above solution is put into practical use, the upper end surface of the bottom plate 18 is inclined by the cone plate 17. The purpose of this is to prevent some particles from being inconvenient to clean up on the upper end surface of the bottom plate 18 when the raw materials are poured out through the discharge port 19 after the plastics are mixed.

[0037] As a further solution of the present invention, a partition is slidably connected inside the chute 14, the bottom of the partition is in contact with the upper end surface of the stirring paddle 15, and a fixing spring for resetting the partition is arranged inside the chute 14;

[0038] When the above scheme is put into actual use, the sleeve rod 13 slides downward on the stirring shaft 23, and a certain space is reserved for the stirring paddle 15 through the slide groove 14. However, plastic particles easily enter this part of the space, resulting in the sleeve rod 13 being unable to move downward smoothly. The partition can prevent plastic particles from entering the slide groove 14, and at the same time will not affect the sliding of the stirring paddle 15 inside the slide groove 14.

[0039] As a further solution of the present invention, the second scraper 27 can be completely fitted with the inner wall of the cylinder 3;

[0040] When the above solution is put into actual use, the second scraper 27 can fit the curved inner wall of the cylinder 3 , so that the cleaning effect of the second scraper 27 on the inner wall of the cylinder 3 can be ensured.

At this time, the stirring motor 1 rotates through the transmission gear cylinder 31 to drive the bottom plate 18 to rotate together, and the bottom plate 18 will drive the connecting rod 21 to rotate, and the first scraper 25 on the side wall of the connecting rod 21 contacts the inner wall of the cylinder 3 to clean the plastic debris attached to the inner wall of the cylinder 3. At the same time, when the bottom plate 18 rotates, the transmission gear 8 will rotate with the threaded rod 22 on the bottom plate 18. When the transmission gear 8 rotates to When it is in the position meshing with the outer rack 4, the transmission gear 8 will drive the threaded rod 22 to rotate together, so that the sliding plate 20 slides downward along the threaded rod 22, thereby removing the slag from the inner wall of the cylinder 3 in the vertical direction through the downward sliding of the second scraper 27. When the transmission gear 8 rotates to the position disengaged from the outer rack 4, the bottom plate 18 continues to rotate so that the transmission gear 8 continues to mesh with the inner rack 5. The inner rack 5 drives the transmission gear 8 to rotate in the opposite direction to the direction when the outer rack 4 drives the transmission gear 8 to rotate, so that the threaded rod 22 reverses the sliding plate 20 and slides upward along the threaded rod 22, thereby resetting the sliding plate 20 upward, and at the same time changing the sliding direction of the second scraper 27 and removing the slag from the inner wall of the stirring motor 1 again.
