Cross-shaped support for a meat mincing machine

Abstract

The invention relates to a cross-shaped support (10) for a meat-mincing machine. The cross-shaped support (10) has a hub (11) with a central bore (15), an outer ring (13), and multiple webs (12) which extend between the hub (11) and the outer ring (13). A groove (14) is provided on the exterior of the outer ring (13) in order to support the cross-shaped support (10) in the meat-mincing machine in a rotationally fixed manner. The cross-shaped support (10) additionally functions as a tool, for example the cross-shaped support has projections (16) which allow a simplification of the assembly or disassembly of the knife pin from the meat-mincing machine (FIG. 1).

Description

(1) The invention is explained in more detail below on the basis of three exemplary embodiments with reference to the drawing, in which:

(2) FIG. 1 shows a perspective view of a cross-shaped support according to the invention,

(3) FIG. 2 shows a known blade journal prior to assembly,

(4) FIG. 3 shows a perspective view of a further cross-shaped support,

(5) FIG. 4 shows a further known blade journal prior to assembly,

(6) FIG. 5 shows a front side of a further cross-shaped support according to the invention,

(7) FIG. 6 is a sectional view of the cross-shaped support according to FIG. 5,

(8) FIG. 7 shows a side view of a bearing bushing, and

(9) FIG. 8 shows a front side of a bearing bushing.

(10) The cross-shaped support 10 shown in the figures is the last element of a cutting set in the meat grinder. In FIG. 1, this cross-shaped support 10 has three webs 12 which connect an outer ring 13 and a central hub 11. A central bore 15 is provided in the hub 11. In this central bore 15, the blade journal 30, shown in FIG. 2, can be received in a rotationally movable manner. In this example, the hub 11 has two noses 16, 16 on its end face. For the rotationally fixed mounting of the cross-shaped support 10 in the meat grinder, there is provided on the outer ring 13 a groove 14 which cooperates with a corresponding adjusting spring on the housing wall of the meat grinder and thus prevents rotational movement of the cross-shaped support 10 during the grinding process. To assemble and disassemble the elements of the cutting set, the adjusting spring is removed and a rotational movement of the cross-shaped support is possible.

(11) FIG. 2 shows the augur 40, the blade journal 30 and the fastening ring 20 used for connecting the blade journal 30 to the augur 40. In addition, two sealing rings 50, 51 are provided in this exemplary embodiment. One end of the blade journal 30 is inserted into the augur 40. A fastening ring 20, which has a matching thread for a screw connection to the augur 40, is pushed over the blade journal 30. Subsequently, the cross-shaped support 10 is also pushed over the narrower part of the blade journal 30 and the cross-shaped support 10 is aligned in such a way that the two noses 16, 16 can engage in the two recesses 21. If the cross-shaped support 10 is pressed tightly against the fastening ring 20, a rotational movement of the cross-shaped support 10 can be carried out. For this purpose, the webs 12 of the cross-shaped support provide a handle. The rotational movement of the cross-shaped support 10 is transmitted by the engagement of the noses 16, 16 into the recesses 21 on the fastening ring 20 and thus the screw connection to the augur 40 is tightened. Removal of the blade journal 30 likewise takes place with the aid of the cross-shaped support 10. Therefore, it is not necessary to provide a separate tool to achieve this removal.

(12) In a further embodiment of the cross-shaped support 10, shown in FIG. 3, two noses 16, 16 are likewise present diametrically opposite on the end face of the hub 11. In this case, the noses 16, 16 are located on the outer edge of the hub 11. This arrangement has been selected so that the noses 16, 16 can engage in edge-side notches 22 of the fastening ring 20, shown in FIG. 4. The mounting and removal process of the blade journal 30 with the aid of the cross-shaped support 10 from FIG. 3 takes place as described in the preceding example.

(13) In a third embodiment of the cross-shaped support 10, shown in FIG. 5 and FIG. 6, the cross-shaped support 10 has a bearing bushing 17 positioned in the central bore 15. Such bearing bushings 17 are used in the case of cross-shaped supports and cutting elements of the meat grinder so that, after a certain period of operation, it is only necessary to replace the bearing bushing and not the entirety of the cross-shaped support or cutting set element. In this embodiment of the cross-shaped support 10, the two noses 16, 16 are located diametrically opposite on the front side of the bearing bushing 17. In the side view of the bearing bushing 17, FIG. 7 clearly shows that the noses 16, 16 protrude from the front side. Here too, the noses 16, 16 are provided on the outer edge of the bearing bushing 17; see FIG. 8. The bearing bushing 17 has an inner bore in which the blade journal 30, shown in FIG. 2, can be accommodated in a rotationally movable manner.

(14) The bearing bushing 17 has a front region (left side of FIG. 7) of larger outer diameter, and a rear region (right side of FIG. 7) with a smaller outer diameter. Suitably, the hub 11 of the cross-shaped support 10 has a central bore 15 with two regions, each of which has a different inner diameter, so that a step is formed. The mounting and removal process of the blade journal 30 with the aid of this cross-shaped support 10 from FIG. 5 takes place as already described. In this case, the step in the interior of the hub 11 prevents the bearing bushing 17 from pressing backwards through the central bore 15 during the assembly or removal process. It forms a stop region for the front region of the bearing bushing 17.

(15) In another embodiment of the bearing bushing, the front region of larger outer diameter is likewise designed as a ring, but the rear region has a shape deviating from the round ring has, for example, a circumferential shape which is oval in cross-section.

(16) For other application examples, elements with a tool function are not merely provided in the region of the hub 11, but also on the webs 12 or the outer ring 13.
