Definitions

  • the disclosure relates to a method for grinding strand-like fibrous material according to the preamble of Claim 1 as filed, and to a device for performing the method according to the preamble of Claim 8 as filed.
  • the fibers and fibrous shreds used in the process are produced beforehand by grinding a strand-like fibrous material.
  • natural fibers such as those made from cellulose are manufactured from this type of fibrous web.
  • the grinding and shredding preferably takes place in what are referred to as hammer mills, where the fibrous material is fed onto the transversely aligned cutting edge of a cutting mechanism and wherein several striking elements arranged on a drum strike one end of the fibrous material projecting over the cutting edge.
  • a device of this type and a method of this type are, for example, already known from DE
  • the cutting edge is formed into a casing by a slotted inlet opening which encases a drum body with a plurality of striking elements.
  • the striking elements are advanced to the inner end of the slot leaving a narrow clearance, such that the incoming fibrous material is ground by the rotating drum body.
  • Devices of this type have the great disadvantage that very irregular fibrous shreds are produced where relatively elastic fibrous materials are used. Due to the elasticity of the fibrous material, the breaks in the fibrous material occur primarily beyond the cutting edge.
  • a method and a device are known with which the fibrous material is immobilized by an additional clamping mechanism in the region of the cutting edge.
  • the known method and the known device are described in EP 0 386 017 Bl.
  • the fibrous material is fed to the cutting edge of the cutting mechanism.
  • a clamping mechanism is arranged at a short distance from the cutting mechanism, which features two opposing clamping jaws that grip on the lower surface and the upper surface of the fibrous material.
  • One of the clamping jaws is designed to be moveable and this results in the fibrous material being clamped in an oscillating manner. Hence, this lends additional stability to the fibrous material during grinding.
  • the known method and the known device have a great disadvantage insofar as the point in time at which the fibrous material is clamped and the point in time at which the fibrous material is ground must be synchronized with each other in order to obtain fibrous shreds in defined sizes. Furthermore, it is impossible with the known method and device to produce very fine fibrous shreds because of the interval as designed between the cutting mechanism and the clamping mechanism.
  • the object of the disclosure is to develop a generic method for grinding fibrous materials and a generic device for performing the method, such that the fibrous material can be continuously ground into very fine fibrous shreds.
  • a further aim of the disclosure is to produce an optimally continuous grinding process with a continuous material feed.
  • This object is achieved according to the present disclosure with a method in which the fibrous material is fed through a clamping gap between the clamping mechanism and the cutting mechanism, which is designed to oscillate, wherein the clamping mechanism is guided in a back and forth clamping movement relative to the cutting mechanism.
  • the solution is achieved by the clamping mechanism and the cutting mechanism being arranged opposite one another in a clamping plane in order to form a clamping gap, wherein the clamping mechanism may be guided in a back and forth clamping movement relative to the cutting mechanism.
  • FIG. 1 is a schematic view of a first embodiment of the device according to the present disclosure for carrying out the method according to the present disclosure.
  • FIG. 2 is a schematic view of a further embodiment of the device according to the present disclosure.
  • FIG. 3 is a schematic cross-sectional view of a further embodiment of the device according to the present disclosure.
  • FIG. 4 is a schematic plan view of the embodiment in FIG. 3.
  • FIG. 5 is a schematic cross-sectional view of the clamping mechanism of the embodiment in FIG. 3.
  • FIG. 6 is a schematic cross-sectional view of the drive shaft of the embodiment of the clamping mechanism in FIG. 5.
  • the disclosure has a particular advantage insofar as the fibrous material is immobilized directly at the cutting edge of the cutting mechanism during grinding. Consequently, the fibrous material may be ground uniformly into very fine fibrous shreds. Undefined breaks in the material beyond the cutting edge are prevented.
  • the cutting mechanism and the clamping mechanism act on the fibrous material in one clamping plane such that the fibrous material is immobilized on its upper surface and on its lower surface in the region of the cutting edge.
  • the cutting edge can be formed on the upper surface or on the lower surface of the fibrous material. Accordingly, the clamping mechanism would be arranged on the lower surface or the upper surface of the fibrous material.
  • the method variation is particularly preferred in which the fibrous material is also transported by a feeding movement of the clamping mechanism relative to the cutting mechanism.
  • the fibrous material may be continuously advanced in the phases in which there is no clamping.
  • a further modification of the device according to the present disclosure features a mechanical linkage by which the clamping mechanism is guided in order to perform a superimposed advancing movement.
  • multiple degrees of freedom of movement at the clamping mechanism may be produced by a drive.
  • the variant method in which the fibrous material is clamped in the clamping gap by multiple movable clamping jaws of the clamping mechanism opposite the cutting mechanism, wherein a number of the clamping jaws are moved asynchronously in parallel and a number of the clamping jaws are moved synchronously.
  • the clamping movements and the advancing movements of the clamping jaws may be made by the clamping jaws moving asynchronously.
  • the synchronously moving clamping jaws which are spread advantageously over the width of the clamping gap, guarantee immobilization as well as a continuous grinding of the fibrous material at the cutting edge of the cutting mechanism.
  • the device features a cutting mechanism for this purpose with multiple clamping jaws which may be moved in parallel, wherein the clamping jaws are divided into a number of drive units and where the clamping jaws of adjacent drive units may be moved asynchronously and the clamping jaws of one of the drive units may be moved synchronously.
  • Dividing the clamping jaws into multiple drive units has the particular advantage that the interaction of the advancing movement and the clamping movement may be produced evenly distributed over the width of the fibrous material. Hence, very large working widths of fibrous material may also be advantageously ground into fibrous shreds.
  • the variation of the method of the disclosure is particularly advantageous in which each of the clamping jaws of the clamping mechanism are moved for clamping and for transporting the fibrous material on an elliptical guide path.
  • the clamping jaws may accomplish a cyclic movement, with which the fibrous material may be continually advanced in the clamping gap.
  • the advancing movement of the clamping jaws essentially determines the length of the ellipse.
  • the mechanical linkage to the clamping jaw drive is designed so that that each of the clamping jaws of the clamping mechanism are movable on an elliptical guide path.
  • the movement of the clamping jaws of the clamping mechanism is produced by a powered drive shaft with a controllable electric motor.
  • the actual advancing movement of the fibrous material may be easily adjusted via a rotational speed control for the drive shaft input speed.
  • the modification of the device of the present disclosure features a drive shaft connected to the mechanical linkage, which is connected to a controllable electric motor and a controller.
  • the drive shaft, and hence the mechanical linkage may be operated at a predetermined rotational speed using the controller and the electric motor.
  • a variation of the method is preferably used, in which the clamping gap between the cutting mechanism and the clamping mechanism is adjusted by setting the spacing for the clamping mechanism to the particular thickness of the fibrous material.
  • the clamping forces acting on the fibrous material may be adjusted such that, along with immobilization, advancing the fibrous material in the clamping gap is also possible.
  • the fibrous material is fragmented at the cutting edge of the cutting mechanism by multiple striking elements attached to a rotating drum, which passes at a short distance from the cutting edge.
  • the striking elements may be operated with a relatively high striking frequency, relative to the cutting edge of the cutting mechanism.
  • the clamping jaws of the clamping mechanism are preferably designed according to a further advantageous modification of the device according to the present disclosure, in which the clamping jaws feature a guide section and a clamp section.
  • the clamp section of the clamping jaw extends parallel to a knife plate forming the cutting edge of the cutting mechanism, where, however, the guide section of the clamping jaw is connected to gear elements of the mechanical linkage by multiple pivots.
  • One of the gear elements is preferably designed as a connecting rod, which is connected to the drive shaft via an eccentric plate, and to the clamping jaw via the pivot. This advantageously allows an oscillating advancing movement to be produced at the clamping jaw. In the process, the superimposed clamping movement is advantageously transferred to the clamping jaw via a cam disk, which cooperates with a guide surface at the guide section of the clamping jaw.
  • the guide section of the clamping jaw In order to maintain the movement of the clamping jaw in a straight alignment to the clamping gap, provision has also been made for the guide section of the clamping jaw to be connected via a further pivot on one lead end to one of multiple sliding blocks, which is guided on a guide rail.
  • the clamping jaws are advantageously designed as bars such that one clamp end on the clamp section faces the lead end of the guide section.
  • the method according to the present disclosure and the device according to the present disclosure are particularly suitable for producing very fine fibers from fibrous materials relatively quickly with a high degree of uniformity.
