[0002] At present, the discharge holes on the die head for strand pelletizing in an extruder are arranged side by side. Usually, the number of holes is 4, 6, 8, 11, etc., and the die head is an integral structure. If it is necessary to replace the die head with a different number of holes, the entire die head needs to be disassembled from the extruder head and then a new die head needs to be installed. In actual production, when producing materials with different materials and different formulas, it is necessary to select a die head with an appropriate number of holes. If the number of holes at the die head is too many, the pressure at the die head will become smaller, resulting in insufficient pressure, the material is not dense, and problems such as broken strips and unsmooth traction will occur; while if the number of holes at the die head is too few, the pressure at the die head will be too large, resulting in the material being extruded quickly, and phenomena such as the material strip rotating and unable to be strung will occur; this leads to the need to replace the die head with an appropriate number of holes according to the produced material, thereby increasing the labor intensity, and the operation is complex and inconvenient.
