Definitions

  • the present invention relates to a mounting device for adjusting and locking in place the knives used in so-called “cutter” machines, used for cutting, grinding, chopping and mixing products, in particular in delicatessen and salting.
  • These machines comprise a certain number of knives (generally between two to eight) arranged on a horizontal axis rotating at high speed in a tank of semi-toric shape.
  • the knives are placed one after the other on this tree, offset by 30, 60, 90, 120, or 180 ° depending on the number of knives used and the nature of the work to be carried out.
  • the present invention therefore relates to a solution for combining an easy installation of knives in the machine, allowing their precise and progressive adjustment, ensuring that this adjustment cannot be modified by the traction exerted by centrifugal force or the efforts encountered during work; more this solution can be implemented by personnel not mechanically qualified; it is solid, hygienic, inexpensive.
  • the knife which retains a usual shape comprising a central fixing zone pierced with an opening of substantially rectangular shape intended for the passage of the machine shaft and a cutting bevel whose characteristics do not have of incidence on the invention, is characterized by two holes located on either side of the substantially rectangular central opening mentioned above, preferably on its major axis or close to it.
  • an adjustment washer of circular shape comprising a central bore whose diameter is adapted to the dimensions of the machine shaft, characterized by the drilling of a fairly large number of holes arranged next to each other, but all at different centers in the center of the washer.
  • a conventional cutter knife 1 has been shown, the cutting area of which is designated by 2.
  • the attachment area 1a lying between the dotted lines 3a and 3b has an opening 4 of substantially rectangular shape but with rounded edges 4a, 4b , whose width allows just the passage of the machine shaft and the length allows this shaft a longitudinal travel allowing to adjust the length of the knife as it wears.
  • Two holes 5a and 5b with counterbores 6a and 6b are machined on either side of the opening 4, on its major axis.
  • the holes 5a-5b are located in the vicinity of the major axis of the opening 4. In addition, these holes are more or less distant from the rounded edges 4a, 4b of the opening 4.
  • an adjustment washer 7 whose circular bore 8 adapts with little play on the machine shaft.
  • a number of holes 10 with counterbores 11 In the space between the bore 8 and the periphery 9 of this adjustment washer is machined a number of holes 10 with counterbores 11.
  • the number of holes, nor their angular arrangement nor the progression of their radii are limiting of the invention.
  • Fig. 3a is a plan view of the stepped and eccentric cam 12. A clear distinction is made between the eccentricity with respect to the threaded hole 13, and the presence of two small holes 14 which allow this cam to rotate with the aid of a claw wrench (not shown).
  • Fig. 3b is a sectional view of this same cam 12 on which the threaded hole 13 and the eccentric stages 15 and 16 are clearly distinguished.
  • Fig. 3c is an elevation view of the screw 17 comprising a wide head 18 which, during assembly, is housed in the counterbore 11 of a hole 10 in the adjusting washer 7, and a slot for a screwdriver 19 which will allow the final tightening of all the elements once the fine adjustment has been made using cam 12.
  • Figs. 3a and 3b make it possible to clearly distinguish the eccentricity 16 of the eccentric cam 12 and the flat 15 which is housed in the countersinking 6a or 6b of one of the holes 5a or 5b of the knife 1.
  • the eccentricity of the cam 16 reaches three millimeters, which makes it possible, on the one hand, to have a fine adjustment capacity of two millimeters which can be used to compensate for the two millimeters of distance between centers existing between two consecutive holes and, on the other hand, to keep a safety margin of one millimeter to compensate for any manufacturing or wear clearances.
  • the user has an adjustment stroke of twenty two millimeters by successively using the twelve holes 10 of the adjustment washer 7 with the only hole 5a of the knife 1, and once these possibilities have been exhausted, it finds an additional adjustment stroke of twenty two millimeters, this time using the hole 5b of the knife 1.
  • the parts described above that is to say the knife 1, the washer 7, the cam 12 are made of high strength steel to be able to ensure sufficient durability for this equipment.
