[0003] The core component of the pelletizer is the forming mold. The material is prepared into pellets after passing through the mold. However, the diameter of the mold hole of the existing mold is fixed, resulting in a constant size of the prepared pellets. When pellets of different sizes need to be prepared, the mold needs to be replaced.

[0004] Therefore, how to adjust the size of the mold hole without replacing the mold is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0009] Furthermore, the inner diameter of each of the telescopic tubes increases sequentially from top to bottom.

[0010] Furthermore, a lifting mechanism is connected to the lower end surface of the discharge plate; the lifting mechanism is suitable for driving the discharge plate to rise and fall so as to retract the corresponding telescopic tube, that is, to select the corresponding telescopic tube as the discharge end.

[0011] Furthermore, the extrusion mechanism includes: a driver and a pressure wheel group; the driver drives the pressure wheel group to roll on the material receiving plate to allow the raw material to enter the diameter adjusting mechanism.

[0012] Furthermore, the peeling mechanism is sleeved on the rotating shaft of the driver and rotates accordingly, and the peeling mechanism is connected to the lifting mechanism to rise and fall accordingly.

[0013] The beneficial effect of the utility model is that the extrusion mechanism of the pelletizer with adjustable die hole diameter is used to extrude the raw material into the forming die, and extrudes it after being formed by the forming die, and finally is cut into granules by the rotary cutting mechanism.
