Eccentric pellet device
Technical field
This utility model relates to a kind of eccentric pellet device, for pelleter.Belong to mechanical equipment technical field.
Background technology
When high-temperature fusion shape material enters die head runner from the end of upstream equipment (generally extruder); material is cut into drop when just leaving die orifice by the pelleter blade of high speed rotating and enters in processing water; owing to the drop-wise polymer of the maximized physical characteristic of particle specific surface area and fusing is with the temperature difference of processing water, drop solidifies and forms the granule close to spheroid.The pelletize mode of this " somewhere between fervent and cold cut critical state " determines it and can be good at competent molten state intensity difference, and viscosity is big, the material granulation operation high to heat sensitivity.
The axle of the blade of existing pellet device and die head are on same axial line, and the cutting effective area of the die head of this kind of structure is one circular (see Fig. 3-4), and therefore extrusion capacity is little, and during work, the pressure of extruder is big, and the service life of reductor is short simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of eccentric pellet device, and with the axle center of die head the most on the same line, therefore the extrusion capacity of die head is big, and the pressure of extruder is little, and cutting efficiency is high in the axle center of cutting knife.
The purpose of this utility model is achieved in that
A kind of eccentric pellet device, including, it is characterized in: described eccentric pellet device includes die head and cutting knife, the most on the same line, the middle section of die head is evenly arranged with nib for the axle center of described die head and the axle center of cutting knife, and edge is provided with fixing hole, described cutting knife includes slitter shaft and blade, described blade has two, and is separately positioned on the both sides of slitter shaft, and the anchor ring that described blade rotates past is completely covered nib.
Compared with prior art, the beneficial effects of the utility model are:
This utility model one bias pellet device, material is extruded from nib, under the effect of the cutting knife of high speed rotating, material is cut into drop and enters in processing water, owing to nib is covered with the central region of die head, compared with existing die head, extrusion capacity is big, the pressure of extruder is little, and the service life of reductor is long.

Detailed description of the invention
See Fig. 1-2, this utility model relates to a kind of eccentric pellet device, it includes die head 1 and cutting knife 2, the axle center of described die head 1 and the axle center of cutting knife 2 are the most on the same line, the middle part of die head 1 is evenly arranged with nib 1.2, edge is provided with fixing hole 1.1, nib 1.2 is for extruded material, fixing hole 1.1 is used for fixing die head 1, described cutting knife 2 includes slitter shaft 2.1 and blade 2.2, described blade 2.2 has two, and is separately positioned on the both sides of slitter shaft 2.1, and the anchor ring that described blade 2.2 rotates past is completely covered nib 1.2.
Operation principle: this utility model is underwater cutpellet pattern, material is extruded from nib 1.2, under the effect of the cutting knife 2 of high speed rotating, material is cut into drop and enters in processing water, owing to nib 1.2 is covered with the central region of die head 1, (see Fig. 3-4) compared with existing die head, extrusion capacity is big, the pressure of extruder is little, and the service life of reductor is long.
