Problems solved by technology

[0005] A disadvantage of such a device capable of coextruding containers to be filled later by means of a filling mandrel is that it is used to mold the coextruded container, then gradually fill the container by means of the filling mandrel, and then close the container. The complex design of the device

Embodiment Construction

[0046] figure 1 A schematic diagram of an extrusion granulator 1 in a granulation system 100 for producing pellet packets 12 is shown. The granulation system 100 has an extrusion device 27 , a supply path 35 , and an extrusion granulator 1 . The extrusion device 27 co-extrudes the filler material 19 in the cladding tube 18 into a plastic strand 28 . The temperature of this plastic strand 28 is regulated in the feed device 17 on the feed path 35 and fed to the extruder 1 .

[0047] The extrusion granulator 1 essentially has a pressure roller 2 and a toothed extrusion roller 3 , which is driven by a drive unit 31 . The squeeze roller 3 is pressed with its teeth 4 against the surface 36 of the pressure roller 2 so that the coextruded filler 19 is metered into the pellet package 12 consisting of the sheath tube 18 by forming the minimum distance a.

[0048] The filled pellet bag 12 is supplied to the drying device 34 by the collection device 29, and the dried and filled pellet...

Abstract

A squeezing-roll granulator which has a squeezing roller pair (60) made of a toothed pressure roller (2) and a toothed squeezing roller (3), wherein the toothing (4) of the pressure roller and of the squeezing roller has tooth flanks (5, 6) which are arranged between a tooth base region (7) and a tooth crown region (8 8'), and wherein the tooth base region has an outer diameter (d) which is smaller than the outer diameter (D) of the tooth crown region, and wherein at least one of the two rollers of the squeezing roller pair has three squeezing zones (9, 10, 11) in the tooth crown region comprising a central squeezing zone (10), these zones define different spacings between the tooth crown regions with a minimum spacing (a) in the region of the central squeezing zone, and wherein the contour of the tooth flanks and of the tooth base region of the rollers of the squeezing roller pair defines a maximum cross section of the granulate cushions (12) to be formed.

Description

technical field [0001] The invention relates to a squeeze roll granulator with a squeeze roll pair having a toothed pinch roll and a toothed pinch roll, the teeth of the pinch roll and the pinch roll having teeth in the tooth root region and the tooth surface between the tooth top area, and the outer diameter of the tooth root area is smaller than the outer diameter of the tooth top area. Background technique [0002] Known from German Patent Disclosure DE 31 45 614 C2 is a squeeze roll granulator for pelletizing strands of plastic material and similar plastic bodies; hereinafter referred to as strands of plastic material and similar plastics The body is a "plastic strip", especially if these strips have a covering tube and a closed filling. The known squeeze roll arrangement has a feed device for at least one outer layer hardened strand which guides the strand to a pair of rollers which can be driven in opposite directions about parallel axes. drive. At least one roller ...
