[0024] As a further feature of the above scheme, the inner roller 22 is provided in two sets, the outer sleeve 21 is provided with a granulation barrel seat 20, and the piston rod 31 is fixedly connected to the granulation barrel seat 20.

[0025] As a further provision of the above scheme, the granulation barrel base 20 is also provided with a number of fixing columns 27 located inside the outer sleeve 21. The fixing columns 27 are provided with fixing plates 28. The inner roller 22 includes an outer pressure roller 222 with a pressure groove 221 and an eccentric crank shaft 223 connected to the drive unit. The other end of the eccentric crank shaft 223 is hinged to the fixing plate 28.

[0026] As a further provision of the above scheme, the pellet mill base 1 is provided with a pellet discharge groove 18 below the pelletizing hole wheel 23, and the bottom of the outer sleeve 21 is provided with a discharge port 218 opposite to the pellet discharge groove 18.

[0027] As a further provision of the above scheme, the feed port 25 includes a feed hole 251 and a push hole 252 for setting the spiral feed shaft. When the granulation barrel assembly 2 is in use, the end of the push hole 252 is located between the inner roller 22 and the granulation hole wheel 23.

[0028] As a further feature of the above scheme, the two ends of the eccentric crank shaft 223 are coaxially arranged, and the middle part is provided with an eccentric part 224. The outer pressure wheel 222 is fixed to the eccentric part 224 and rotates eccentrically due to its rotation.

[0029] refer to Figures 1-5 The granulation barrel structure of an EVA pelletizer according to this embodiment is shown. The pelletizer includes a pelletizer base 1 and a granulation barrel assembly 2, as shown. Figure 1 The pellet mill base 1 shown in this embodiment is equipped with a motor 11, a reducer 12, and a guide rail 13, and references Figure 3 The granulation barrel assembly 2 shown is provided with a granulation barrel seat 20, and the piston rod 31 of the drive cylinder 3 provided on the pellet mill base 1 is fixedly connected to the granulation barrel seat 20. The drive cylinder 3 can drive the granulation barrel seat 20 of the granulation barrel assembly 2 and the granulation hole wheel 23 provided on the granulation barrel seat 20, which includes an outer sleeve 21 and an inner roller 22, to move relative to each other and connected to the output main shaft of the reducer 12.

[0030] Furthermore, in this embodiment, the inner roller 22 is provided with a drive unit located rotatably inside the outer sleeve 21, and the inner roller 22 includes an outer pressure roller 222 with a pressure groove 221 and an eccentric crank shaft 223 connected to the drive unit. The other end of the eccentric crank shaft 223 is hinged to the fixed plate 28. The two ends of the eccentric crank shaft 223 are coaxially arranged, and an eccentric part 224 is provided in the middle. The outer pressure roller 222 is fixed to the eccentric part 224 and rotates eccentrically due to its rotation.

[0031] As described above, in this embodiment, the inner roller 22, through its eccentric rotation design, rotates within the granulation hole roller 23 while pressing the material. Furthermore, its rotation path is minimized when it is close to the bottom of the inner side of the granulation hole roller 23. This utilizes the rotational deviation pressure to create a crushing and extruding force between the granulation hole roller 23 and the inner roller 22, squeezing the rubber material out from the holes in the inner wall of the granulation hole roller 23, causing it to fall into the outer sleeve 21, and then pass through the discharge port 218 and the granulation groove 18 along the inner wall of the outer sleeve 21.

[0032] Furthermore, in this embodiment, the granulating perforated wheel 23 is located between the outer sleeve 21 and the inner roller 22 when the granulation barrel assembly 2 is working. As mentioned above, during its operation, the inner roller 22, which rotates inside the granulating perforated wheel 23, cooperates with the granulating perforated wheel 23, which rotates in the opposite direction, to form a rotational crushing and extruding force, squeezing the material out into the outermost outer sleeve 21 for collection. In this embodiment, the outer sleeve 21 is also provided with a feed inlet 25, which includes a feed hole 251 and a push hole 252 for setting a spiral feeding shaft. When the granulation barrel assembly 2 is working, it is located between the inner roller 22 and the granulating perforated wheel 23. The material pushed in by the spiral feeding shaft is fed into the inner roller 22 from the push hole 252. As it falls, it is squeezed and crushed by the inner roller 22. The material is granulated through the eccentric rotational force of the inner roller 22 and the rotational cooperation of the granulating perforated wheel 23.

Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
