Definitions

  • the invention relates to a meat grinder with cutting elements and with a screw conveyor which is rotatably mounted in a housing and is connected to a knife pin.
  • the various cutting elements include, for example, a perforated disc, knife and/or pre-cutter.
  • one end of the blade pin is connected to the screw conveyor in a rotationally fixed manner and, starting from the point of connection with the screw conveyor, has an axially extending support section on which the rotationally fixed knives are mounted. This ensures that the knives rotate at the same speed during one revolution of the conveyor screw.
  • the perforated discs mounted adjacent to the knives are supported in a stationary manner on the meat grinder housing during such a rotation and have a central hub through which the knife pin passes.
  • Known knife pins have different cross sections, for example according to DE 26 49 305 C3 and US 4.018390A a support portion for the knife in square shape and according to DE 20 2020 102 505 U1 a support section in the form of a dihedron with a bevel on one edge for coding. Furthermore, it is off DE 809 769 B known to use a knife pin with a cross-section in the form of an asymmetrical polygon.
  • connections between the auger and the knife pivot are in the DE 100 26 825 C2 , namely a keyway connection or in DE 80 32 323 U1 , namely a press connection shown. These connections also enable easy assembly of the knife pin, but can no longer be detached after a long period of use.
  • the object of the present invention is to provide a meat grinder with a drivable screw conveyor, in which the knife pin can be easily connected to the screw conveyor and also easily detached again.
  • the torque of the conveyor screw is transmitted to the blade pin and thus to the blade.
  • this meat grinder has a screw conveyor which is mounted in the meat grinder housing and can be driven in particular by an electric motor.
  • a knife pin is mounted in a rotationally fixed manner on this auger, one end of which is detachably held on the auger.
  • the meat grinder also includes at least one blade set, it being possible for a blade set to include various cutting elements.
  • Such cutting elements are, for example, perforated disks and pre-cutters that are stationarily supported on the meat grinder housing.
  • Such cutting elements also include knives which are mounted in a rotationally fixed manner on a carrying section of the knife pin and which interact with perforated disks arranged adjacent to them in order to mince the meat.
  • the knife pin is inserted with its one end, the insertion end, in a bearing hole in the screw conveyor. This is not one press connection.
  • the insertion end of the blade pin is adapted to the shape of the bearing bore.
  • the shape of the knife pin is unchanged in the axial direction, i.e. in the conveying direction.
  • the cross section of the supporting section of the knife pin and of the connecting section with the screw conveyor at the insertion end of the knife pin can be any desired polygonal cross section, for example a so-called dihedron with two mutually parallel transmission surfaces for the torque.
  • the cross-sectional shape of the support section and the connecting section at the insertion end of the knife pin can be the same or different.
  • the insertion end of the blade pin has a larger circumference than the support section on which the blade rests.
  • the cross-sectional shape of the insertion end and the support section can be the same, but also different. With regard to the cross-section of the insertion end and the supporting section, it is important in each case that rotary entrainment is ensured.
  • the cross-sectional shape of the insertion end and the support section of the knife pin is the same.
  • the shank has a larger circumference, protrudes beyond the support section in the radial direction, preferably starting from the central axis, the support section is protruded evenly from the shank on the circumference.
  • a stop surface is formed on the peripheral side in the transition area between the shank end and the support section. This stop surface serves as a stop for a fastening ring.
  • This fastening ring has a correspondingly large opening so that it can be pushed from the rear end of the support section up to the stop surface. This opening of the fastening ring is so large that a rotation of the blade pivot is not impeded. On the other hand, the opening is so small that the mounting ring does not fit over the shank of the knife tang.
  • the support section of the knife spigot and the shank of the knife stub have a different cross-sectional shape or the same cross-sectional shape, but in a radially offset arrangement, so that the shank end projects beyond the support section at least at several circumferential points or sections, if not on the circumferential side, and overlaps in the transition area between the insertion end and the support section, one or more stop surfaces for the separate fastening ring result on the peripheral side.
  • connection is a detachable connection, with the fastening ring and the screw conveyor having matching connection means, namely suitable form-fitting and/or force-fitting connections, e.g. a screw connection or a tongue/groove connection, preferably a screw connection.
  • the mounting ring has external threads on its peripheral surface and the auger has mating internal threads.
  • a cylindrical bushing with a corresponding internal thread is provided at the output end in front of the bearing bore in the screw conveyor.
  • the fastening ring is also pushed over the support section up to the stop surface and the insertion end of the blade pin is inserted into the bearing bore. Since the opening of the fastening ring is smaller than the diameter of the shank, the knife pin is held in position axially by the screw connection between the fastening ring and the screw conveyor. The assembly of the knife pin the screw conveyor is possible in a simple manner. The transmission of torque between the auger and the knife pin is ensured by the coordinated cross-sections of the shank and bearing bore.
  • such a knife pin is easier to detach from the screw conveyor than known knife pins.
  • damage to the blade pin in particular is avoided, since the forces for loosening the screw connection act exclusively on the fastening ring.
  • handling means are present on the fastening ring, for example in the form of grooves or notches. When loosening the screw connection, these handling means offer access options for suitable tools.
  • the fastening ring has a circumferential rib on its peripheral surface which cooperates with an annular groove in the cylindrical bushing at the output end in front of the bearing bore in the auger.
  • Other non-positive and/or positive connections for connecting the fastening ring can also be used, such as hooks.
  • Bayonet locks such as those known for attaching a lens to a camera, can also be used, namely by providing lugs on the attachment ring and corresponding recesses in the cylindrical bushing.
  • connection between the knife pin and the screw conveyor can be sealed by means of sealing rings in order to prevent material to be shredded from penetrating into the area of the screw connection and the bearing bore.
  • the new meat grinder has, in a known manner, a drivable auger and a non-rotatable bearing on the auger Knife pin which can advantageously be easily connected to an auger by means of a fastening ring.
  • This connection can be easily released in the same way, damage to the knife pin being avoided when the connection is released.
  • the screw conveyor 10, the blade pin 20 and the fastening ring 30 used to connect the blade pin 20 to the screw conveyor 10 are shown in a perspective view.
  • Two sealing rings 40, 41 are also provided in this exemplary embodiment.
  • In 1 shows the conveying direction of the comminuted material in the meat grinder.
  • the knife pin 20 has a front insertion end 21, a transition region 26 and a support section 23 on which knives can be arranged in a rotationally fixed manner.
  • the screw conveyor 10 has a bearing bore 11 for the insertion end 21 of the knife pin 20 .
  • the cross section of this bearing bore 11 is adapted to the cross section of the shank 21 , ie it has two straight side surfaces which are arranged parallel to one another both on the shank 21 of the knife pin 20 and in the bearing bore 11 of the screw conveyor 10 . These straight side surfaces are used for torque transmission and are each connected to one another via an outwardly curved side surface.
  • the support section 23 also has the shape of a dihedron.
  • the coordinated cross sections of the insertion end 21 and the bearing bush 11 as well as the support section 23 and the recess in the blade ensure that when the screw conveyor 10 rotates, the blade pin 20 and also the blade rotate.
  • the knife is not shown here. During such rotation, the knife pin 20 is held in position axially by means of the fastening ring 30 .
  • the fastening ring 30 is slipped onto the blade pin 20 from the rear end of the blade pin 20 in the conveying direction FR.
  • the fastening ring 30 is pushed over the support section 23 of the knife pin 20 to the transition region 26, where its front side comes into contact with a stop surface 22, since the opening 31 of the fastening ring 30 is smaller than the cross section of the insertion end 21 of the knife pin 20.
  • the transition region 26 between the insertion end 21 and the support section 23 of the knife pin 20 has a round cross section.
  • the diameter of the transition area 26 is adapted to the diameter of the opening 31 of the fastening ring 30, so that rotation of the knife pin 20 is not impeded.
  • the stop surface 22 is aligned in the radial direction at an angle to the conveying direction.
  • the fastening ring has an inner cone at the end of the opening 31 facing the conveyor screw.
  • Other forms of the stop surface 22 are also possible, and the opening 31 of the fastening ring 30 is advantageously adapted to them.
  • the knife pin 20 is inserted with its insertion end 21 into the bearing bore 11 and the mounting ring 30 resting on the transition area 26 is connected to the screw conveyor 10 .
  • the screw conveyor 10 has a cylindrical bushing with an internal thread 13 in front of the bearing bore 11 . This internal thread 13 interacts with an external thread 32 on the peripheral surface of the fastening ring 30 .
  • the screw connection between the fastening ring 30 and the auger 10 simultaneously establishes a connection between the knife pin 20 and the auger 10 .
  • the blade pin 20 When the blade pin 20 is mounted, it carries the blade of the mincer in the support section 23 and ensures, via a non-rotatable connection with these blades, that when the screw conveyor 10 rotates, the latter also move.
  • the fastening ring 30 has an edge 35 on the side facing away from the screw conveyor 10, i.e. on its rear side.
  • This edge 35 protrudes circumferentially in the radial direction over this rear side.
  • the fastening ring 30 is screwed into the cylindrical bushing of the screw conveyor 10 and closes the cylindrical bushing of the screw conveyor 10 with its edge 35.
  • the interior of the screw conveyor can be sealed by sealing rings 40, 41.
  • a front sealing ring 41 in the conveying direction FR is inserted into the cylindrical bushing of the conveyor screw 10 before assembly and lies there on a contact surface 12.
  • This contact surface 12 represents the exit of the bearing bore 11.
  • the second rear sealing ring 40 in the conveying direction FR is placed in front of the Mounting pushed onto the fastening ring 30 and held in this case in an annular groove between the edge 35 and the external thread 32.
  • the interior of the screw conveyor 10 is sealed against the crushing chamber of the meat grinder and thus against the ingress of material to be crushed.
  • the blade pin 20 After inserting the blade pin 20 and screwing the fastening ring 30 into the cylindrical bushing of the screw conveyor 10, the blade pin 20 is held axially firmly on the screw conveyor 10 and is non-rotatably connected to it.
  • This screw connection can be loosened without damaging the knife pin 20 since no torque is exerted on the knife pin 20 when the fastening ring 30 is loosened.
  • notches 34 are provided on the edge 35 of the fastening ring 30 for producing the screw connection, but in particular also for loosening the screw connection.
  • a corresponding auxiliary tool can engage in these notches 34 in order to apply a rotation to loosen the screw connection.
  • Other handling means are also possible.
  • a support section 23 can have a rib or inclined surface running in the conveying direction as a code for the knife pin 20, which cooperates with a suitable code on the knife side.
  • a corresponding receiver can be provided on the knife pin 20 or a connection to such a receiver in the meat grinder can be established via an axial bore 25.
  • the detachable connection between the fastening ring 30 and the screw conveyor 10 is a screw connection.
  • other known non-positive and/or positive connections are provided.
