Definitions

  • the invention relates to cutting mills, the housing of which is divided into an upper part and a lower part in a plane running through the axis of their cutting rotor, the upper part being pivotably connected to the lower part about an axis parallel to the axis of the cutting rotor and the cutting rotor being mounted in the upper part . It relates to an advantageous safety lock for such a cutting mill, by which reaching into moving cutting knives is prevented when the cutting mill is opened.
  • the invention has for its object to provide a safety lock for a granulator of the type described above, which is simple in construction and handling and all safety requirements. enough.
  • the solution to this problem is that the cutting rotor is driven directly via a coupling by a drive motor fastened together with the lower part of the cutting mill housing on a common base plate, and the drive motor with the coupling half seated on its shaft is moved so far in the axial direction when the cutting rotor is at a standstill can cause both coupling halves to disengage completely.
  • This ensures that the cutting mill cannot be opened during operation, since the hinged upper housing part is locked by the coupling, and that the cutting rotor must be completely disconnected from the drive to open the cutting mill, i.e. reaching into the running cutting rotor is prevented and a start of the cutting rotor when the upper part of the housing is open is not possible either by an electrical fault or by deliberate switch bridging.
  • Another advantage is when the upper part of the housing is opened, that the cutting rotor for knife adjustment can be gently positioned by hand by turning the coupling half that is now exposed, without having to reach into the knife.
  • a release device To disengage the motor, a release device must be provided, which inevitably interacts with a limit switch located in the motor circuit. This arrangement serves to prevent the clutch from disengaging under load.
  • Any arrangement suitable for this purpose can be used as the disengaging device, for example a simple swivel lever or one that can be operated with a hand crank Spindle drive.
  • the limit switch must be arranged in such a way that the drive comes to an immediate standstill at the start of the shifting process and can only be switched on again when the clutch is fully engaged. If necessary, it can be useful for machines with overrun to provide an automatically acting braking device which is effective immediately when the motor circuit is interrupted and which brings the rotating machine parts to a standstill very quickly.
  • a directly coupled geared motor is used for the drive, especially with a relatively low output speed, since such a motor stops on its own with practically no overrun if the motor circuit is interrupted.
  • the coupling can be covered by two hoods, one of which is attached to the drive motor and the other to the swiveling upper housing part, and which, when the coupling is engaged, overlap with their edges by approximately the axial displacement path of the drive motor. This ensures that it is not possible to intervene between the coupling halves even when the clutch is disengaged.
  • the housing of the cutting mill consists of the lower part 1, the upper part 2 and the side shields 3 fastened on the end face of the latter. It thus forms a cutting chamber in which the cutting rotor 4 is rotatably mounted and interacts with the knives 5 fastened to the upper part 2.
  • the cutting chamber is limited by sieve 6.
  • the milling cutter-shaped cutting rotor 4 here has helical cutting edges 7 which are arranged in accordance with an arrow tooth system. This ensures that the material circulating in the cutting chamber is conveyed to the center of the cutting rotor, so that its end faces are relieved of the material and smearing on the side plates 3 of the housing, in particular in the case of thermoplastic material, is avoided.
  • the clearing strips 11 on the end faces of the cutting rotor 4 have a supportive effect here and convey material that has come between the cutting rotor 4 and the side plate 3 back to the circumference of the cutting rotor 4.
  • the shaft 8 of the cutting rotor 4 is connected by the coupling 9 directly to the drive motor 10 designed as a geared motor.
  • the material to be comminuted is fed to the cutting mill via the chute 12 and, after comminution and passage through the openings of the sieve 6, is pneumatically drawn off from the suction trough 13.
  • the cutting mill is fastened with its lower part 1 on the mobile base plate 14.
  • This base plate 14 also carries the device for axially displacing the drive motor 10 (FIG.
  • the peripheral speed of the cutting edges 7 is 0.5 to 2 m / s).
  • the axial displacement path is determined by the dimension of the elongated holes 16; it is so large that the two coupling halves 9a and 9b are completely separated from one another in the disengaged state (FIG. 4).
  • the safety lock caused by the coupling 9 is thus canceled and the upper part 2 can be pivoted upwards together with the cutting rotor 4 (FIG. 5).
  • the two hoods 24 and 25 are provided, of which the hood 24 is connected to the drive motor 10 and the hood 25 to the upper part 2. In the engaged state of the clutch, the hoods 24 and 25 overlap with their edges by approximately the axial displacement path of the drive motor 10 (FIG. 1).
  • the cutting mill described here is designed as a stand-alone machine for a plastic-processing injection molding machine, the task of which is to shred the sprue and scrap parts directly on the injection molding machine, so that the granules obtained can be returned to the processing process immediately.
