Definitions

  • the invention relates to a hides cleaning machine for the use in the tan industry to remove the residual impurities, such as small shreds, fibres or fragments of a hide unrelated to the hide surface.
  • the processing of milling causes, in fact, a natural accumulation of electrostatic charges on the faces of the hides, favouring the sticking of extraneous particles, especially the fibres which usually get detached from the grain side of the hides, as known the lower and less valuable layer of the derma of the hide.
  • the processing of perching, with which the hides are stressed in order to soften them causes, for its part, the partial or complete detachment of shreds from the grain side.
  • the defects must be eliminated before the semifinished hides are subjected to another processing.
  • the functioning of the dust removers firstly consists of blowing air on the hide, to raise the dust, the impurities or other extraneous particles, and subsequently of sucking them.
  • a machine of recent conception which can be found in the tan field, allows to remove the residual impurities, which remain stuck to the hide surface even after being treated with dust removers or brushing machines and comprises the features of the preamble of claim 1.
  • the machine includes a support framework which assures on a support structure and is provided with a conveyor belt receiving the hide to be cleaned.
  • the machine includes, also, cleaning means, for example, a series of rollers or a closed loop belt, facing the support framework, which cooperate by contact with the hide surface in order to remove impurities, dust or shreds thereof.
  • cleaning means for example, a series of rollers or a closed loop belt, facing the support framework, which cooperate by contact with the hide surface in order to remove impurities, dust or shreds thereof.
  • the main purpose of the present invention is to provide a machine for the cleaning of hides which keeps unchanged its performance longer than the equivalent machines of the known type.
  • aim of the invention is to carry out a machine for the cleaning of hides in which the cleaning means remain for times longer than those of the prior art in a optimum efficiency state or at least adequate to the use, without this being due to their replacement and/or maintenance.
  • a last but not least aim of the present invention is to make available a machine for the cleaning of hides of simple and economic construction.

  • the machine of the invention restores at the original state or at an appropriate state the cleaning means which previously have removed impurities, shreds or dust from the hide.
  • regeneration means remove from the cleaning means the extraneous bodies which have been collected from the hide, ensuring the same cleaning means the possibility of repeating effectively, at a later stage, the operation to which they are responsible.
  • the machine of which the protection is required performs in line the operation of regeneration of the cleaning means, without the need to separate the members involved.
  • the regeneration of the cleaning means occurs using tools of simple construction, maintenance-friendly, able to keep intact over time their own function.
