Definitions

  • the present invention relates to the field of carding, and relates in particular to a carding device comprising a comb cleaning device.
  • the carding machines provide a non-woven web from which impurities (such as short fibers and dust) are removed.
  • a conventional carding machine has a main drum with a spiked coating for the actual carding operation and supplied with raw fibers through a feed cylinder, and a comber which is a cylinder positioned against the main drum and configured to collect the fibers worked on the main drum to create a non-woven web.
  • Delicate fibers such as natural fibers and glass fibers tend to break and release dust and impurities during the carding process. This dust and these impurities get to the bottom of the linings of the various cylinders of the carding machine, which is particularly penalizing as regards the lining of the comb.
  • the comb which is the cylinder which allows the creation of the veil, is the essential element concerning the quality of the product.
  • the lining of the comb becomes clogged, in particular with dust and / or impurities, in the context of carding delicate fibers, the web produced is inhomogeneous and has holes. It is then necessary to stop the production line to clean the comb.
  • the present invention aims to resolve the drawbacks of the prior state of the art, by proposing a carding device comprising a comb cleaning device, said comb cleaning device allowing automatic and permanent cleaning of the comb of the carding device, which makes it possible to create a higher quality veil, and which allows an increase in production with fewer line stoppages due to cleaning.
  • the present invention therefore relates to a carding device, comprising a main drum and a comber with an axis parallel to that of the main drum and positioned against the main drum and downstream of the main drum in the direction of flow of the fibers, the direction of rotation of the comb being opposed to that of the main drum, characterized in that the carding device further comprises a comb cleaning device comprising a dust collecting cylinder with an axis parallel to that of the main drum and positioned against the comb and a cleaning cylinder with an axis parallel to that of the main drum and positioned both against the dust collecting cylinder and against the main drum, the direction of rotation of the dust collecting cylinder being the same as that of the comb, and the direction of rotation of the cleaning cylinder being identical to that of the dust collection cylinder.
  • a comb cleaning device comprising a dust collecting cylinder with an axis parallel to that of the main drum and positioned against the comb and a cleaning cylinder with an axis parallel to that of the main drum and positioned both against the
  • the transfer of dust and impurities between the dust collection cylinder and the cleaning cylinder is effected by a set of angles on the linings of these cylinders.
  • the comb cleaning device allows an automatic and permanent cleaning of the comb of the carding device, which creates a high-quality, homogeneous, hole-free web.
  • the dust collection cylinder is configured to collect the dust present at the bottom of the comber liner, and the cleaning cylinder is configured to automatically and gradually collect the dust on the dust collection cylinder to then return it to the main drum.
  • the dust and impurities contained in the bottom of the comb lining are carried away by the dust recovery cylinder then by the cleaning cylinder which allows constant cleaning of the dust recovery cylinder, the main drum finally taking up this dust and impurities.
  • the carding device could also include a food cylinder placed against the main drum upstream of the latter in the direction of circulation of the fibers, without departing from the scope of the present invention.
  • the axes of the various cylinders of the carding device are driven in rotation by any suitable device, for example one or more motors driving a set of belts.
  • the directions of rotation of the various cylinders of the carding device allow the automatic passage of dust from the comb to the main drum.
  • the dust recovery cylinder and the cleaning cylinder are arranged above the duster.
  • the dust collection cylinder has a flexible or rigid lining, preferably flexible.
  • the main drum, the comb and the cleaning cylinder each have a rigid lining.
  • the cleaning cylinder may also have a soft lining.
  • the lining of each of the main drum and of the cleaning cylinder has teeth inclined in the direction of rotation of the associated element
  • the lining of each of the dust collection cylinder and of the comb has teeth inclined in the direction opposite to the direction of rotation of the associated element
  • the teeth of the lining of the dust collection cylinder are longer than the teeth of the comb lining, to at least penetrate the top of the teeth of the comb lining in order to clean the latter.
  • the teeth of the lining of the cleaning cylinder are longer than the teeth of the lining of the dust collection cylinder, to at least penetrate the top of the teeth of the lining of the dust collection cylinder in order to clean the latter.
  • the teeth of the linings of the main drum are inclined in the direction of flow of the fibers.
  • the carding device further comprises a detacher cylinder positioned against the comb and downstream of the comb in the direction of flow of the fibers.
  • the peeler cylinder is configured to peel the web of nonwoven from the comber.
  • the diameter of the comb is smaller than that of the main drum.
  • the diameter of the dust collection cylinder is smaller than that of the comb.

  • the diameter of the comber can be between 500 and 700 mm
  • the diameter of the dust collection cylinder can be between 200 and 350 mm
  • the diameter of the cleaning cylinder can be between 100 and 200 m.
  • the speed of rotation of the cleaning cylinder is greater than that of the dust collection cylinder and less than that of the main drum.
  • the higher speed of the cleaning cylinder compared to the dust collection cylinder allows more dust to be collected on the dust collection cylinder.
  • the speed of the cleaning cylinder is never greater than that of the main drum to allow dust collection by the main drum.
  • the speed of rotation of the main drum can be between 750 and 1100 rev / min
  • the speed of rotation of the comb can be between 20 and 250 rev / min
  • the speed of rotation of the cylinder of dust recovery can be between 50 and 300 rev / min
  • the rotation speed of the cleaning cylinder can be between 50 and 400 rev / min
  • the rotational speed of the stripper cylinder can be between 50 and 400 rev / min .
  • the subject of the invention is also a carding machine, characterized in that it comprises a carding device as defined above, the main drum of which is fed by a food cylinder.
  • FIG. 1 is a schematic side view of a carding device according to the present invention.
  • the carding device 1 comprises a main drum 2 and a comber 3 with an axis parallel to that of the main drum 2 and positioned against the main drum 2 and downstream of the main drum 2 in the direction of fiber circulation, the direction of rotation of the comber 3 being opposite to that of the main drum 2.
  • the diameter of the comb 3 is smaller than that of the main drum 2.
