Problems solved by technology

Among them, the pelletizing knife is mainly a rotary cutter. The disadvantage is that after the speed of the pelletizing knife increases, a large amount of heat will accumulate at the edge of the knife; due to the high-speed rotation, the stress at the bearing will deteriorate and the friction will increase, causing the temperature in the bearing box to increase. Rise up rapidly, shorten bearing life, reduce cutting efficiency, and reduce the service life of the granulator

Embodiment Construction

[0017] like figure 1 , figure 2 As shown, the present invention provides a granulator, comprising a feeding cylinder 1 connected in sequence, a stirring device, an extruding device and a pelletizing device, and the pelletizing device includes a pelletizing knife 6, a driving motor 9, and a drive rod 10, the return spring 7 and the eccentric wheel 8, the granulator 6 is connected to the transmission rod 10, one end of the return spring 7 is fixed and the other end is connected to the transmission rod 10, and the eccentric wheel 8 is connected to the drive rod 10. The motor 9 is connected, and the eccentric wheel 8 is in line contact with the transmission rod 10 .

[0018] The pelletizing knife 6 is polygonal, and each side of the pelletizing knife has a blade, preferably the number of sides of the pelletizing knife is 3 or 4. Setting the granulation knife as a polygonal blade can increase the service life of a granulation knife. Only one of the granulation knife edges is use...

Abstract

The invention provides a pelletizer. The pelletizer comprises a feeding tube, a stirring device, an extrusion device and a pelletizing device, which are successively connected. The pelletizing device comprises a pelletizing knife, a driving motor, a transmission rod, a reset spring and an eccentric wheel. The cut pelletizing knife is connected with the transmission rod; one end of the reset spring is fixed, and the other end is connected to the transmission rod; and the eccentric wheel is connected with the driving motor and in line contact with the transmission rod. The invention has the following beneficial effects: the pelletizing device is flexible and convenient for usage; an independent cutter head ensures that pelletized particles will not block the cutting tool; and the double-sided blade has the advantages of simple structure, convenient replacement, long service life and high production efficiency.

Description

technical field [0001] The invention belongs to the field of granule forming equipment, and in particular relates to a granulation device of a granulator. Background technique [0002] In the prior art, the strip granulator is widely used, which is mainly composed of a molding device and a pelletizing device. Among them, the pelletizing knife is mainly a rotary cutter. The disadvantage is that after the speed of the pelletizing knife increases, a large amount of heat will accumulate at the edge of the knife; due to the high-speed rotation, the stress at the bearing will deteriorate and the friction will increase, causing the temperature in the bearing box to increase. The rapid rise will shorten the bearing life, reduce the cutting efficiency, and reduce the service life of the pelletizer. Contents of the invention [0003] The problem to be solved by the invention is to provide a granulator, especially a granulator with convenient replacement of granulator and improved s...
