Pelletizing system

Abstract

A pelletizing system including a supporting rail, a pelletizer that is suspended from the supporting rail, a suspension base, a supporting arm, and an articulated arm. The supporting arm is supported at a first end on the suspension base by means of a first swivel joint and is hinged to the supporting rail at a second end by means of a second swivel joint. The articulated arm includes a first articulated arm branch which is connected to a second articulated arm branch by a third swivel joint. The first articulated arm branch is supported on the suspension base by means of a fourth swivel joint, and the second articulated arm branch is hinged to the supporting rail by means of a fifth swivel joint. In an embodiment, the first through fifth swivel joints each have an essentially vertical swivel axis.

13. The pelletizing system according to claim 9, wherein the suspension base is attached to a housing of the pelletizing system, or is implemented as a single part therewith.

14. The pelletizing system according to claim 13, wherein the housing is a control cabinet housing or a housing for an ancillary component of the pelletizing system.

15. The pelletizing system according to claim 9, wherein the pelletizer is implemented as an underwater pelletizer or an air-cooled die-face pelletizer.

16. The pelletizing system according to claim 9, wherein the pelletizer includes a die plate unit and a cutter head unit, which are detachably connected and separately suspended from the supporting rail.

17. The pelletizing system according to claim 9, additionally comprising at least one extrusion system.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The invention is described in greater detail below with reference to the drawings:

(2) FIGS. 1 to 3 schematically show a pelletizing system in a side view, top view, and front view;

(3) 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(4) Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

(5) 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.

(6) 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.

(7) 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.

(8) The invention being thus described, it will be apparent that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be recognized by one skilled in the art are intended to be included within the scope of the following claims.
