[0022] Specifically, the stirring assembly 3 includes a horizontal plate 31, a motor 32, a rotating rod 33, a stirring rod 34, a connecting column 35, a rotating plate 36 and a lifting assembly 37, wherein a horizontal plate 31 is arranged at the upper end of the upper shell 7, a motor 32 is arranged on both sides of the upper end of the horizontal plate 31, a rotating rod 33 is arranged at the output end of the motor 32, a stirring rod 34 is arranged on the lower side of the surface of the rotating rod 33, a connecting column 35 is arranged at the lower end of the rotating rod 33, a rotating plate 36 is arranged at the lower end of the connecting column 35, and a lifting assembly 37 is arranged between the horizontal plate 31 and the upper shell 7.

[0023] By adopting the above technical solution, when the modified plastic needs to be mixed, the two motors 32 are turned on to drive the two rotating rods 33 to rotate towards each other. The two rotating rods 33 rotate towards each other to drive the several stirring rods 34 to rotate and mix the modified plastic. At the same time, the rotating rods 33 can drive the rotating plate 36 to rotate through the connecting column 35. The rotation of the rotating plate 36 can clean the upper end of the screen plate 8 to avoid clogging of the screen plate 8. By setting the stirring component 3, the mixing and stirring effect of the modified plastic is better.

[0024] Specifically, the lifting assembly 37 includes a fixed frame 371, a second motor 372, a screw rod 373 and a slide groove 374, wherein a fixed frame 371 is provided at the upper end of the upper shell 7, a second motor 372 is provided at the upper end of the fixed frame 371, a screw rod 373 is provided at the output end of the second motor 372, and a slide groove 374 corresponding to the horizontal plate 31 is provided in the fixed frame 371.

[0025] By adopting the above technical solution, when the stirring rod 34 rotates to mix and stir the modified plastic, the motor 2 372 is turned on to drive the screw rod 373 to rotate. The rotation of the screw rod 373 can drive the cross plate 31 to slide in the slide groove 374 of the fixed frame 371. The movement of the cross plate 31 drives the stirring rod 34 on the rotating rod 33 to rise and fall in the lower shell 1. The movement of the stirring rod 34 can stir the modified plastics of different heights in the lower shell 1, so that the mixing and stirring range of the stirring rod 34 is wider.

By setting the stirring component 3, when the modified plastic needs to be mixed, two motors 32 are turned on to drive two rotating rods 33 to rotate towards each other. The two rotating rods 33 rotate towards each other to drive a plurality of stirring rods 34 to rotate to mix and stir the modified plastic. At the same time, the rotating rod 33 can drive the rotating plate through the connecting column 35 36 rotates, and the rotation of the rotating plate 36 can clean the upper end of the screen plate 8 to avoid clogging of the screen plate 8. By setting the stirring component 3, the mixing and stirring effect of the modified plastic is better. When the stirring rod 34 rotates to mix and stir the modified plastic, the motor 2 372 is turned on to drive the screw rod 373 to rotate. The rotation of the screw rod 373 can drive the cross plate 31 to slide in the slide groove 374 of the fixed frame 371. The movement of the cross plate 31 drives the stirring rod 34 on the rotating rod 33 to rise and fall in the lower shell body 1. The movement of the stirring rod 34 can stir the modified plastics of different heights in the lower shell body 1, so that the mixing and stirring range of the stirring rod 34 is wider.
