Definitions

  • the invention relates to a device for shredding a material to be shredded, in particular for the meat processing industry, with at least one fixed perforated plate, in front of which a cutting element rotates, which is connected in a rotationally fixed manner to a shaft which is accommodated in a cutting housing.
  • WO 00 2012 095 083 A1 shows a cutting system consisting of stationary and rotating ones Perforated plates.
  • a spacer ring is provided in a central guide bore of a stationary perforated plate, which is rotatably arranged on a main axis and rotates with the cutting perforated plates, which, due to its thickness, in particular in the case of several cutting sets, determines the axial distance from the rotating cutting perforated plate to the next rotating cutting perforated plate in the conveying direction.
  • a regrinding of the Perforated panels are inexpensive because no exact perforated panel thicknesses, including tolerances, have to be adhered to. This means that a customer can regrind the perforated plates themselves.
  • EP 2 987 557 B1 describes a cutting set which consists of stationary and rotating perforated plates.
  • the stationary and rotating perforated plates are almost adjacent to each other, on the order of one or more thousandths of a mm, and are only separated from each other by a very thin film of lubricant, which is formed by the product itself.
  • the entire arrangement is preceded by a stationary perforated plate and a cutter head.
  • the gap between the first stationary perforated plate and the cutter head is adjustable.
  • the shaft on which the rotating perforated plate is located is moved axially.
  • the axial adjustment can be done, for example, using a handwheel. However, if a distance is to be set reproducibly, a servomotor is required for the axial movement.
  • the object of the present invention is to develop a device of the above-mentioned type for bone-containing, heavily tendon or hard products, which functions stably and reproducibly guarantees the desired product quality. At the same time, wear on the cutting elements should be significantly reduced. Solution to the task
  • a jam finger ring is arranged between the cutting housing, the fixed perforated plate and the rotating cutting element, which is axially displaceable in the direction of the shaft.
  • the device is then disassembled again, cleaned and the next time it is reassembled, the gap between the perforated plates or between the perforated plate and the cutting blades of the cutter head is reduced again to 0, although the distance has changed relatively due to wear.
  • This wear is compensated for by the fact that the front of the jam finger ring is supported elastically against the cutting housing or a separate inlet housing. For example, this is done by a bolt that is spring-loaded in a blind hole in the Staufinger ring.
  • the stationary perforated plate should be supported against a shoulder in the jam finger ring opposite the elastic support. This means that the entire arrangement is clamped around the rotating cutting element.
  • FIG. 2 shows an enlarged detail B from the device according to Figure 1;
  • Figure 3 is a perspective view of a pre-cutter
  • Figure 4 shows an enlarged detail from Figure 1 with the pre-cutter according to Figure 3 inserted;
  • Figure 5 shows a partially illustrated longitudinal section through the device according to Figure 1 during assembly
  • Figure 6 shows an enlarged detail D from the longitudinal section of the device according to the invention according to Figure 5;
  • Figure 7 shows a partially illustrated longitudinal section through a further exemplary embodiment of a device according to the invention for shredding a material to be shredded
  • Figure 8 shows a partially illustrated longitudinal section through the device according to Figure 7 during assembly
  • Figure 9 shows an enlarged section C from Figure 7 during assembly
  • Figure 10 shows an enlarged section C from Figure 7 during assembly, taking wear of cutting blades into account.
  • a device P according to the invention for shredding a material to be shredded has an inlet housing 1 for the material to be shredded, which is followed by a cutting housing 2.
  • the cutting housing 2 is followed by an outlet housing 3 with an outlet pipe 4.
  • An ejector 5 sits in the outlet housing 3 and is placed in a rotationally fixed manner on the end of a shaft 6, which is connected to a drive, not shown.
  • a fixed perforated plate 7 adjoins the ejector 5 and is inserted on the circumference in a shoulder 8 of a Staufinger ring 9.
  • This Saufinger ring 9 sits slidably in the cutting housing 2 and surrounds a rotating cutting element 10, which in the exemplary embodiment shown is also designed as a perforated plate, but can also be any cutting head.
  • This rotating cutting element 10 sits non-rotatably on the shaft 6, to which it is connected via pins 11.
  • the Staufinger ring 9 On its periphery, the Staufinger ring 9 has blind holes 12, in each of which an eccentric bolt 13 sits, which is supported in the blind hole 12 against a coil spring 14.
  • the eccentric bolt 13 is secured via an annular collar 15, which is part of the Staufinger ring 9 and partially overlaps the blind hole 12, so that the eccentric bolt 13 with a head 16 strikes the annular collar 15 from the inside.
  • the rotating cutting element 10 within the Saufinger ring 9 can be placed in front of a pre-cutter 17 shown in FIG.
  • This pre-cutter 17 is equipped with corresponding cutting blades 18.
  • the assembly according to the invention of the device for shredding a material to be shredded is described in more detail with reference to Figures 5 and 6:
  • the jam finger ring 9 is inserted, whereby it slides in the cutting housing 2 until it abuts the inlet housing 1 with the bolt 13.
  • the rotating cutting element 10 and possibly the pre-cutter 17 are inserted into the Staufingerring 9 and the fixed perforated plate 7 is inserted into the shoulder 8 of the Staufingerring 9.
  • a separate clamping disk 19, which is centered by pins 20, is then placed on the shaft end and pressed against the perforated plate 7 by means of a nut 21. This results in an axial offset of the perforated plate 7 along a shaft axis A, with this perforated plate 7 taking the Staufinger ring 9 with it.
  • this cutter head 25 is preceded by a displacement head 27, which only serves to convey the product in the axial direction or in the direction of the shaft axis G.
  • the fixed perforated plate 7 is followed by two pairs, each consisting of a rotating perforated plate 10.1 and 10.2 and a fixed perforated plate 7.1 and 7.2. Both pairs sit in a z-shaped ring 28.1 and 28.2, which are also slidably arranged in the cutting housing 2.
  • the perforated plates maintain a distance in the 10th range, preferably from 20 to 25/100, from each other.
  • each ring 28.1 and 28.2 offers a respective shoulder 8.1 and 8.2 for the fixed cutting element 7.1 and 7.2, respectively, with a leading finger 29.1 or 29.2 of the ring 28.1 or 28.2 pointing to a preceding fixed perforated plate 7 or 7.1 presses.
  • a spacer ring 30 is inserted between the threaded ring 24 on the last fixed perforated plate 7.2.
  • the device according to the invention is assembled in the manner described above, so that reference is only made here to the graphic representation according to Figure 8, since only the tension disk 19.1 is designed differently.
  • the diameter of the holes in the rotating perforated plate 10.2 is larger than the diameter of the previous rotating perforated plate 10.1. This allows the product to relax better towards the back and emulsify better.
  • the diameter order for the arrangement with five consecutive perforated plates is 10 mm - 7 mm - 5 mm - 10 mm - 2 mm.
  • a 2-plate and a 5-plate machine are shown.
  • a 3-plate machine is also possible, for example by removing the two perforated plates 7.2 and 10.2 as well as the ring 28.2 and widening the spacer ring 30.
