Pelleting machine for producing pellets from a strand
Pelleting machine for producing pellets from a strand
A pelleting machine used in a pellet producing process has a rotary cutter mounted to the outer periphery of a hollow rotary shaft. A fixed blade is disposed opposite to the rotary cutter, and a pellet exhaust chute is disposed below the rotary cutter and slopes downwardly therefrom. The rotary cutter is provided with an interior cooling chamber and the hollow rotary shaft is provided with water inflow holes and exhaust holes communicating with the cooling chamber of the rotary cutter.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a pelleting machine for producing pellets from a strand by cutting a strand formed and extruded from a die mounted on a head of an extruder with a cooled rotary cutter.
2. Description of the Prior Art
Conventionally, in a known device for producing pelleters, the pellets are produced by cutting a strand cooled in a water reservoir by a fixed blade and a rotary cutter mounted on a steel belt.
In other words, the rotary cutter generate heat, and synthetic resin in the materials of the strands sticks to the rotary cutter and the fixed blade, thereby providing a poor cutting force and nonuniformity of the cutting size of the pellets. Furthermore, static electricity occurs, thereby adhering the pellets in lumps to each other.
In the known pelleting machine, a plurality of strands extruded from the extruder are passed through the cooling reservoir to cool them sufficiently, and are then cut by the rotary cutter into pellets. Thereafter, the hot cut pellets are thrown into the water reservoir for cooling the pellets.
SUMMARY OF THE INVENTION
Therefore, an object of the present flaker belt is to provide a pelleting machine for producing pellets from a strand which can easily cut strands extruded from an extruder by a cooled rotary cutter to produce pellets of uniform size and shape.
According to the present invention, the pelleting machine installed in a pelleting process is provided with a rotary cutter having a cooling chamber communicated with water inflow holes and exhaust holes formed in a hollow rotary shaft, strands extruded from a die mounted in a head of an extruder are cut by the rotary cutter, cooled and prevented from heating by supplying water, thereto rotary cutter is prevented from adhering to the synthetic resin of the material of the strand increasing the effeciency of cutting and the durability, of the machine.
