PELLETIZING SYSTEM

Abstract

The present innovation concerns pelletizing system, comprising a supporting rail (3); a pelletizer (5) that is suspended from the supporting rail (3); a suspension base (2); a supporting arm (10) that is supported at a first end on the suspension base (2) by means of a first swivel joint (11) and is hinged to the supporting rail (3) at a second end by means of a second swivel joint (12); and an articulated arm (20) with a first articulated arm branch (21), which is connected to a second articulated arm branch (22) by a third swivel joint (23), wherein the first articulated arm branch (21) is supported on the suspension base (2) by means of a fourth swivel joint (24), and the second articulated arm branch (22) is hinged to the supporting rail (3) by means of a fifth swivel joint (25), wherein the first through fifth swivel joints (11, 12, 23, 24, 25) each have an essentially vertical swivel axis.

Claims

1. Pelletizing system, comprising a supporting rail (3); a pelletizer (5) that is suspended from the supporting rail (3); a suspension base (2); a supporting arm (10) that is supported at a first end on the suspension base (2) by means of a first swivel joint (11) and is hinged to the supporting rail (3) at a second end by means of a second swivel joint (12); and an articulated arm (20) with a first articulated arm branch (21), which is connected to a second articulated arm branch (22) by a third swivel joint (23), wherein the first articulated arm branch (21) is supported on the suspension base (2) by means of a fourth swivel joint (24), and the second articulated arm branch (22) is hinged to the supporting rail (3) by means of a fifth swivel joint (25), wherein the first through fifth swivel joints (11, 12, 23, 24, 25) each have an essentially vertical swivel axis.

2. Pelletizing system according to claim 1, wherein the first swivel joint (11) and the fourth swivel joint (24) have the same swivel axis.

3. Pelletizing system according to claim 1, wherein the pelletizer (5) is arranged so as to be movable in a longitudinal direction of the supporting rail (3).

4. Pelletizing system according to claim 1, wherein the suspension base (2) is attached to a housing, in particular a control cabinet housing or a housing for an ancillary component, of the pelletizing system, or is implemented as a single part therewith.

5. Pelletizing system according to claim 1, wherein the pelletizer (5) is implemented as an underwater pelletizer or an air-cooled die-face pelletizer.

6. Pelletizing system according to claim 1, wherein the pelletizer (5) comprises a die plate unit and a cutter head unit, which are detachably connected and separately suspended from the supporting rail (3).

7. Pelletizing system according to claim 1, additionally comprising at least one extrusion system.

Description

[0015] The invention is described in greater detail below with reference to the drawings:

[0016] FIGS. 1 to 3 schematically show a pelletizing system in a side view, top view, and front view;

[0017] FIG. 4 schematically shows a front view of an exemplary embodiment in which a supporting arm and an articulated arm are linked to a suspension base such that they rotate about the same swivel axis.

[0018] Schematically shown in FIGS. 1 to 3 is a pelletizing system 1 in which a pelletizer 5 is suspended from a supporting rail 3, for example by means of rollers 4, so that the pelletizer 3 can be moved in the longitudinal direction of the supporting rail.

[0019] The supporting rail 3, in turn, is attached to a suspension base 2 through a supporting arm 10 and an articulated arm 20. More precisely, the supporting arm 10 is supported at a first end on the suspension base 2 by means of a first swivel joint 11, and is hinged to the supporting rail 3 at a second end by means of a second swivel joint 12. The articulated arm 20 is composed of a first articulated arm branch 21, which is connected to a second articulated arm branch 22 by a third swivel joint 2. The first articulated arm branch 21 is supported on the suspension base 2 by means of a fourth swivel joint 24, and the second articulated arm branch 22 is hinged to the supporting rail 3 by means of a fifth swivel joint 25. The supporting arm 10 and the articulated arm branches 21, 22 of the articulated arm 20 can thus be pivoted relative to one another in an essentially horizontal plane, with the result that the supporting rail can be displaced in the horizontal plane, for example can be moved closer to the suspension base 2 and farther away from it.

[0020] FIGS. 1 to 3 show an exemplary embodiment in which the supporting arm 10 and the articulated arm 20 are located on separate swivel joints 11, 24 that are offset laterally from one another. Alternatively, however, it is also possible to implement the swivel joints 11, 24 as shown in FIG. 4 such that they share the same swivel axis.
