Definitions

  • the invention relates to a meat chopping machine with at least one cutting set consisting of a perforated disk fixed to the housing and a cutter head held in a rotationally fixed manner on a drive shaft, the cutter blades of each cutter head being pressed against their associated perforated plate with a predetermined minimum load on the motor and with a reduction in the load of the latter can be lifted off.
  • the shredding machine described at the outset which has become known from DE-A-1 657 220, brings an improvement in that its knife blades are only pressed against the perforated disk when the shredding machine is actually being fed with shredded material. Once this is processed and there is no further replenishment, they lift off the assigned perforated disc, and you avoid unnecessary wear on the knife sheaths, even when the machine is running.
  • a disadvantage of this construction is that the part of the cutter head carrying the cutter blades is pressed hydraulically against the perforated disk.
  • the hydraulic medium must be supplied via the rotating shaft and led out of it in the area of the cutter head. This requires a complex seal. If the latter fails, the blade cannot be pressed against the perforated disc.
  • the pressure with which the knife blades are pressed against the perforated disc must always be kept constant so that there is no relative displacement of the knife head with respect to the shaft.
  • the material to be cut tends to lift the cutter head off the perforated disc. How strong this tendency is depends not least on the material to be cut. In this respect, a constant contact pressure is not guaranteed with this known shredding machine because the knife blades cannot be safely removed from the perforated disc.
  • the object of the invention is therefore to develop a comminution machine of the type described at the outset in such a way that the knife blades rest securely on the associated perforated disk.
  • the shredding machine is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim.
  • each cutter head can assume two defined end positions in relation to its assigned perforated disk, one being the working position in which the material to be shredded is cut, while the other is an idle position in which the knife blades are lifted off the assigned perforated disk.
  • These two end positions of the cutter head or cutters can be achieved by an axial displacement of the drive shaft which holds them in a rotationally fixed and axially immovable manner.
  • each of the two end positions can be fixed by means of a clamping device, which can in particular be controlled electronically, the control system causing each knife blade to be lifted from its perforated disc at the moment when the load falls below the predetermined minimum value.
  • the electronic control system causes the drive shaft to be disk-mounted with the cutter head or cutters against the perforated disk or perforated disks, so that cutting is carried out again.
  • the clamping device fixes the drive shaft and thus the cutter heads in both end positions, i. H. When cutting, this fixation also ensures that the knife blades are pressed securely onto their perforated disc regardless of the material to be cut.
  • tensioning device can be actuated pneumatically, hydraulically or electromagnetically.
  • a threaded sleeve is supported on the drive shaft in the axial direction, for example by means of an annular disk, an annular collar or the like, which is rotatable by means of an actuator and whose external thread is fixed in the internal thread of a surrounding this threaded sleeve Bearing bushing or the like engages.
  • This threaded sleeve can be rotated with respect to the fixed bearing bush in such a way that the threaded sleeve and with it also the drive shaft are given an axial displacement, which in turn results in a corresponding lifting of the knife blades arranged on the cutter head from the opposing perforated disk or in a setting thereof.
  • the aforementioned threaded sleeve can also partially protrude in the axial direction over the surrounding bearing bush and pass into a cylindrical jacket in this area, around which a clamping ring of the above-mentioned clamping device then grips, which in its clamping position grips the threaded sleeve and with this also fixes the drive shaft carrying the cutter head in its respective position, in its In contrast, the open position allows the threaded sleeve to be rotated by means of the servomotor and thus also allows the drive shaft to be axially displaced.
  • the said threaded sleeve is connected to a worm wheel or the like arranged coaxially therewith, in which a worm shaft driven by the servomotor can engage.
  • the worm shaft of the servomotor is advantageously assigned a lockable handle or the like which permits displacement of the drive shaft carrying the cutter head .
  • the meat shredder shown in side view in FIG. 1 has a pedestal 1 on which a machine housing denoted by 2 is seated.
  • a bearing housing 3 is formed, which serves to receive and support a drive shaft designated 4, which is rotated by an electric motor 6 via an elastic coupling 5.
  • an inlet housing 8 having a funnel 7 is also formed, on the side facing away from the electric motor 6 a cutting head designated 9 is arranged, into which the end of the drive shaft 4 designated 10 projects.
  • This cutting head 9 is covered by an outlet housing 11, the ejection opening of which is designated by 12.
  • two perforated plates 13 and 14 are arranged in a fixed manner one behind the other in the axial direction and fixed by means of a ring mount 15, a jam ring 16 and a support ring 17 located between the two perforated plates 13 and 14.
  • These two perforated plates 13 and 14 are assigned cutter heads, designated 18 and 19, which are each equipped with a plurality of cutter blades 20.
  • These two cutter heads 18 and 19 are pushed and locked on the free end 10 of the drive shaft 4.
  • the shaft part 21 which is adjacent to this shaft end 10 and extends through the inlet housing 8 is covered by a sleeve 22 which rotates together with the drive shaft 4.
  • the machine housing 2 is used to mount a fixed bearing bush 23, in the internal thread 24 of which a rotatable threaded sleeve 26 having an external thread 25 is partially screwed in.
  • the part 27 of this threaded sleeve 26 projecting beyond this fixed bearing bush 23 is cylindrical in shape and is supported on the casing of the drive shaft 4 by a ring cover designated by 28, the shaft part 29 of which is supported in the threaded sleeve 26 by means of ball bearings 30.
  • a worm wheel designated 31 is fastened, into which a worm shaft 34, which is rotated by a servomotor 32 via chain wheels 33, engages.
  • FIGS. 1 and 2 results in a clamping ring 35 belonging to a clamping device engaging around the cylindrical bushing part 27, which is to be clamped and released by means of a clamping bolt designated by 36 and a clamping nut 37 belonging to this.
  • the tensioning and loosening of this clamping ring 35 takes place by means of a pneumatic cylinder 38, the piston rod 39 of which is articulated on a crank designated 40, which is given a pivoting movement in the direction of arrow 41 when the piston rod 39 is lifted.
  • tightening or loosening of the clamping nut 37 takes place, which in turn results in a corresponding tightening or loosening of the clamping ring 35.
  • the workflow in this meat chopping machine is as follows: In the working position of the drive shaft 4 shown in FIG. 1 and also the cutter heads 18 and 19 arranged on it, the piston rod 39 assumes its rest position, shown in solid lines, in which the clamping nut 37 is tightened and the Tension ring 35 are tensioned.
  • This clamping ring 35 fully includes the cylindrical bush part 27, so that twisting of the threaded sleeve 26 is not possible. However, this means that the drive shaft 4 is secured against any axial displacement.
  • the material to be cut is introduced in the direction of arrow 42 into the hopper 7, from which it arrives in the direction of the arrows 43 to the cutter heads 18 and 19 and the associated perforated plates 13 and 14 in order to move in the direction of the Arrow 44 to exit through the ejection opening 12 located in the outlet housing 11.
  • the worm shaft 34 is also assigned a handwheel designated by 47, by means of which, independently of the servomotor 32 the drive shaft and with this the two cutter heads can be manually axially displaced.
