By providing the protrusion 12, the fixing groove 13, the mounting block 14, the discharge pipe 15, the fixing block 16, the rotating groove 17, the threaded rod 18 and the turning handle 19, a better use effect is achieved. When the discharge pipe 15 needs to be replaced during use, the turning handle 19 can be pinched to rotate, so that the threaded rod 18 can rotate backward inside the fixed block 16 through the rotating groove 17. When the threaded rod 18 is completely rotated out of the fixed block 16 through the rotating groove 17, After the threaded rod 18 is turned out of the inside of the protrusion 12 through the fixing groove 13, the mounting block 14 can be pinched and pulled to the left, so that the mounting block 14 slides to the left on the surface of the protrusion 12. When the mounting block 14 completely slides out of the inside of the protrusion 12, it can be replaced, thereby avoiding the situation that the discharge pipe 15 of the existing extruder is mostly directly fixed on the left side of the shell 8, which will cause inconvenience in replacing it when facing different needs during long-term use. The stirring paddle 7 is rotatably connected to the material tank 4, and the fixing grooves 13 are symmetrically distributed at the front and rear ends of the protrusion 12, which makes it more convenient for the stirring paddle 7 to rotate, and prevents the stirring paddle 7 from being stuck by the material tank 4 during use.

The fixed block 16 is symmetrically distributed at the front and rear ends of the mounting block 14. The threaded rod 18 is rotatably connected to the fixed block 16, the threaded rod 18 is rotatably connected to the mounting block 14, and the threaded rod 18 is rotatably connected to the protrusion 12, which is more convenient for the threaded rod 18 to rotate, and the threaded rod 18 is prevented from being stuck by the fixed block 16 or the mounting block 14 during use. The turning handle 19 is rotatably connected to the fixed block 16, and the turning handle 19 is rotatably connected to the shell 8, which is more convenient for the turning handle 19 to rotate.This prevents the handle 19 from being stuck by the fixing block 16 during use, causing the handle 19 to be unable to continue rotating.

[0025] Embodiment 2

[0026] See also Figure 1-3 5. A limit plate 20 is fixedly installed on the surface of the controller 9, a limit groove 21 is provided inside the limit plate 20, and a limit block 22 is slidably connected inside the limit groove 21. A sliding rod 23 is fixedly installed in the middle of the limit block 22, and a scraper 24 is fixedly installed on the back of the sliding rod 23. A pinching plate 25 is fixedly installed on the surface of the sliding rod 23, which is more convenient for cleaning the display screen 10. When cleaning is needed after long-term use, the pinching plate 25 can be pushed and pulled to make the sliding rod 23 slide in the middle of the limit plate 20 through the limit block 22 and the limit groove 21. At this time, the sliding rod 23 will drive the scraper 24 to slide in the middle of the limit plate 20. The scraper 24 can move and scrape off the dust on the surface of the display screen 10, thereby preventing the display screen 10 from having a poor use effect due to excessive dust on the surface of the display screen 10 after long-term use. The limit plates 20 are symmetrically distributed at the upper and lower ends of the surface of the controller 9. The limit block 22 is slidably connected to the limit plate 20, the sliding rod 23 is slidably connected to the limit plate 20, and the scraper 24 is slidably connected to the limit plate 20, which makes it easier for the limit block 22 and the sliding rod 23 to slide, and avoids the limit block 22 and the sliding rod 23 being stuck by the limit plate 20 during use, causing the limit block 22 and the sliding rod 23 to be unable to continue sliding.

[0027] Working principle: When in use, first place the base 1 at the required position, then pour the raw materials into the inside of the material tank 4, then start the motor 6 on the top of the top plate 5, so that the stirring paddle 7 stirs the raw materials in the material tank 4, and the stirred raw materials will flow into the inside of the conduit 3, then start the button 11 on the surface of the controller 9, so that the extruder 2 pushes the raw materials into the inside of the shell 8 through the conduit 3, and completes the extrusion through the discharge pipe 15, and the data will be displayed on the display screen 10 during use. When it is necessary to replace the discharge pipe 15 during use, the handle 19 can be pinched and rotated to make the threaded rod 18 rotate backward inside the fixed block 16 through the rotating groove 17. When the threaded rod 18 passes After the rotating groove 17 is completely rotated out of the interior of the fixing block 16 and the threaded rod 18 is rotated out of the interior of the protrusion 12 through the fixing groove 13, the installation block 14 is pinched and pulled to the left, so that the installation block 14 slides to the left on the surface of the protrusion 12. When the installation block 14 completely slides out of the interior of the protrusion 12, it can be replaced. After long-term use, when it is necessary to clean the display screen 10, the pinching plate 25 can be pinched and pushed and pulled, so that the sliding rod 23 passes through the limiting block 22 and the limiting groove 21 to slide in the middle of the limiting plate 20, and the sliding rod 23 drives the scraper 24 to slide. At this time, the surface of the scraper 24 can scrape off the dust on the surface of the display screen 10, thereby avoiding the occurrence of poor use effect.
