Abstract
The present invention relates to a vacuum drying machine for tanned skins, with multiple work surfaces, which comprises a fixed framework with at least two substantially vertical uprights which extend to the side of a plurality of vertically movable stacked platforms, each of which upwardly defines a work surface, and is provided below with a cover for the underlying platform. The vacuum drying machine is characterized in that at least one of the platforms is characterized in that at least one of the platforms is coupled to the movable liners of at least two linear double-action cylinders, each one being located at one of the uprights, the upper ends of the stems thereof being connected to the top of the matching upright.
Claims19
Vacuum drying machine for tanned skins with multiple work surfaces, comprising:
- a fixed framework formed from at least a pair of substantially vertical uprights each having a top, a mounting base and vertical guide means;
- a plurality of substantially horizontal elongated platforms having longitudinal axes, longitudinal sides and transverse sides, each platform being arranged for vertical movement along said guide means;
- each of said platforms defining an upper work surface for supporting a skin to be treated and a lower face having a cover for sealingly engaging with an underlying adjacent platform to define a drying chamber;
- heating means arranged within said platforms for heating the skins to be dried;
- suction means connected to each platform to provide a vacuum within said chamber;
- a plurality of double-acting hydraulic cylinders each having a liner and a stem, at least one of said platforms being coupled to at least one pair of said cylinders, said at least one pair of cylinders adapted to move vertically said at least one platform relative to said framework;
- said plurality of cylinders have movable liners and stationary stems having upper free ends and connecting joints provided at the upper free end of said stems to suspend the cylinder downwardly from the top of a corresponding vertical upright, said at least one platform being coupled to the movable liners of said at least one pair of cylinders at a predetermined level accessible to an operator with said pair of cylinders in a fully extended condition.
