Abstract
A strand pelletizer for pelletizing a strand of material comprises at least one cutting edge and an opposite cutting edge. The opposite cutting edge is arranged on a base body which is displaceable relative to a support body. The base body is independently displaceable in a linear manner relative to the support body and pivotable about at least one pivot axis. The strand pelletizer enables simple and precise adjustment of the opposite cutting edge and an associated cutting gap.

A strand pelletizer for pelletizing a strand of material with
- at least one cutting edge,
- an opposite cutting edge, wherein
- the opposite cutting edge is arranged on a base body and
- the base body is linearly displaceable relative to a support body for adjusting the opposite cutting edge,
- a feeding device for feeding a material strand into a cutting gap between the at least one cutting edge and the opposite cutting edge,
- a first adjustment screw and a first pin which forms a first pivot axis and is displaceable by means of the first adjustment screw,
- a second adjustment screw and a second pin which forms a second pivot axis and is displaceable by means of the second adjustment screw,
- wherein the first adjustment screw is arranged on the support body and is connected to the first pin which is mounted on the base body so that the base body is pivotable relative to the support body about the second pivot axis, and
- wherein the second adjustment screw is arranged on the support body and is connected to the second pin which is mounted on the base body so that the base body is pivotable relative to the support body about the first pivot axis.
A method for adjusting a cutting gap of a strand pelletizer comprising the steps of:
- providing a strand pelletizer for pelletizing a strand of material with
- at least one cutting edge,
- an opposite cutting edge, wherein
- the opposite cutting edge is arranged on a base body and
- the base body is linearly displaceable relative to a support body for adjusting the opposite cutting edge, and
- a feeding device for feeding a material strand into a cutting gap between the at least one cutting edge and the opposite cutting edge,
- a first adjustment screw and a first pin which forms a first pivot axis and is displaceable by means of the first adjustment screw,
- a second adjustment screw and a second pin which forms a second pivot axis and is displaceable by means of the second adjustment screw,
- wherein the first adjustment screw is arranged on the support body and is connected to the first pin which is mounted on the base body so that the base body is pivotable relative to the support body about the second pivot axis, and
- wherein the second adjustment screw is arranged on the support body and is connected to the second pin which is mounted on the base body so that the base body is pivotable relative to the support body about the first pivot axis, and
- at least one of linearly displacing the base body relative to the support body and pivoting of the base body relative to the support body about at least one of the first pivot axis and the second pivot axis for adjusting the cutting gap.
