Definitions

the present invention relates to the field of carding, and relates in particular to a carding device comprising a device for cleaning a doffer.
carding machines When fed with raw fibers, carding machines provide a nonwoven web whose impurities (such as short fibers and dusts) are eliminated.
a conventional carding machine has a main drum with a spiky coating for the actual carding operation and fed with raw fibers through a food roll, and a doffer which is a cylinder positioned against the main drum and configured to recover the fibers worked on the main drum to create a nonwoven web.
Delicate fibers such as natural fibers and glass fibers tend to break and drop dust and impurities during the carding process. This dust and these impurities are placed at the bottom of the lining of the various cylinders of the carding machine, which is particularly penalizing with regard to the filling of the doffer.
the doffer which is the cylinder that allows the creation of the veil, is the essential element concerning the quality of the product.

the transfer of dust and impurities between the dust collection cylinder and the cleaning cylinder is done by a set of angles on the liners of these cylinders.
the comb cleaning device allows automatic and permanent cleaning of the comb of the carding device, which allows to create a veil of superior quality homogeneous and without hole.
the dust collection cylinder is configured to recover the dust present at the bottom of the comb lining, and the cleaning cylinder is configured to automatically recover dust as it goes along the dust collection cylinder and then return it to the main drum.
the dust and impurities contained in the bottom of the lining of the doffer are carried by the dust recovery cylinder and then by the cleaning cylinder which allows a constant cleaning of the dust recovery cylinder, the main drum finally taking up these dusts and impurities.
the carding device could also include a food cylinder disposed against the main drum upstream thereof in the direction of flow of the fibers, without departing from the scope of the present invention.
the axes of the various cylinders of the carding device are rotated by any appropriate 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 the dust from the dancer to the main drum.
the dust collection cylinder and the cleaning cylinder are arranged above the doffer.
the dust recovery cylinder has a flexible or rigid lining, preferably flexible.
the main drum, the doffer and the cleaning cylinder each have a rigid lining.
the cleaning cylinder may also have a soft liner.
the lining of each of the main drum and the cleaning cylinder has teeth inclined in the direction of rotation of the associated element, and the lining of each of the dust collection cylinder and the doffer possesses 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 lining of the doffer, to at least penetrate the top of the teeth of the lining of the doffer to clean them.
the teeth of the lining of the cleaning cylinder are longer than the teeth of the liner of the dust collection cylinder, to at least penetrate the top of the teeth of the lining of the dust recovery cylinder to clean them.
the teeth of the main drum linings are inclined in the direction of flow of the fibers.
the carding device further comprises a detaching cylinder positioned against the doffer and downstream of the doffer in the direction of circulation of the fibers.
the detaching cylinder is configured to detach the nonwoven web from the doffer.
the diameter of the doffer is smaller than that of the main drum.
the diameter of the dust recovery cylinder is smaller than that of the doffer.
the diameter of the cleaning cylinder is smaller than that of the dust recovery cylinder.
the diameter of the main drum may be between 1200 and 1500 mm
the diameter of the doffer may be between 500 and 700 mm
the diameter of the dust recovery cylinder may be between 200 and 350 mm
the diameter of the cleaning cylinder can be between 100 and 200 m.
the rotational speed of the cleaning cylinder is greater than that of the dust recovery cylinder and less than that of the main drum.
the higher speed of the cleaning cylinder with respect to the dust collection cylinder makes it possible to recover more dust on the dust collection cylinder.
the speed of the cleaning cylinder is never greater than that of the main drum to allow the recovery of dust by the main drum.
the rotation speed of the main drum can be between 750 and 1100 rev / min
the speed of rotation of the doffer 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 stripping cylinder can be between 50 and 400 rev / min .
the invention also relates to a carding machine, characterized in that it comprises a carding device as defined above, the main drum is fed by a food cylinder.
the carding device 1 comprises a main drum 2 and a doffer 3 of 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 flow of the fibers, the direction of rotation of the doffer 3 being opposite that of the main drum 2.
the diameter of the doffer 3 is smaller than that of the main drum 2.
the direction of flow of the fibers corresponds to the direction in which the fibers circulate in the carding device 1, raw fibers being fed to the main drum 2 and a fleece of nonwoven coming out of the doffer 3.
the carding device 1 could also comprise a food cylinder disposed against the main drum 2 and upstream thereof in the direction of flow of the fibers, without departing from the scope of the present invention.
