Definitions
- the present invention falls within the technical field of the paper industry, particularly in the field of papermaking machines and, more particularly to cellulose pulp strip cutting devices.
- the paper is manufactured from cellulose pulp strips obtained from the corresponding raw materials.
- Cellulose pulp bands which usually have a thickness of about 2 mm, are cut transversely into pieces of certain lengths by means of a transverse cutting device to obtain sheets or sheets of a certain width.
- the cut sheets will be used to make paper, cardboard, etc. on separate production lines.
- the pasta production lines where the cross-cutting device is integrated, are found in pulp production plants, usually in countries where their raw materials are found, such as Brazil, ought, Argentina, Chile, Canada , Norway, etc., while paper mills are distributed all over the world.
- the cross-section of the cellulose pulp is carried out by means of devices comprising a rotating blade incorporated in a cylinder with an axis driven by one or more motors and a cross-member or counter-knife, arranged at the opposite side of the blade. At each turn of the blade there is a cross section in the pulp band.
- the rotation of the blade is synchronized to produce transverse cuts to a certain and constant length to obtain pieces of cellulose pulp with a certain length, the length of the cut also depending on the cut. linear development of the cylinder.
- the cross section is produced continuously as cellulose pulp passes.
- This cross section of the pulp presents as a main problem that the relatively high thickness (approximately 2 mm.) Of the cellulose pulp, and that the cellulose pulp is flexible, so that the cutting of the blade presses the material and causes defects of quality known in the sector as "fish-eye".
- the roller carrying the or Blades are contracted so it is necessary, in some cases, to heat the blade to start a new cutting cycle.
- each roller can be arranged on an axis that is not perpendicular to the direction of advance of the cellulose pulp web, and the blade is arranged forming an axial segment of propeller extending from one end of the roller to another. This combination allows the cut to be made transversely to the feed.
- Each roller can incorporate more than one blade to adapt the position of the cross-section to the required lengths of the sheets (sheets). With this system, it is not necessary to heat the blades since the scissors cut causes one blade to penetrate with respect to the other and the contact is not lost even if the rollers cool and contract slightly. The life of the blades is also longer, fewer foundations are required for the machine and the cutting produces less dust.
- the present invention aims at overcoming the drawbacks of the state of the art detailed above, by means of a transverse cutting device of cellulose pulp strips comprising a first rotating cutting roller on which at least one radially emerging first blade is mounted of the outer surface and between the ends of the first rotating roller, and a second rotating cross-cutting roller on which at least two second emerging blades, in the cutting position, of the outer surface and arranged between the ends of the second roller are mounted rotary;
- the rotating rollers are mounted on two coaxial axes of rotation propelled by at least one propeller motor;
- the blades being arranged in respective positions such that, in their cutting position they coincide, by rotating the rollers in a transverse cutting line, perpendicular to the direction of advancement of a band of cellulose pulp (5) that travels between the rollers ;
- At least one of the second blades is a fixed blade mounted on one of the rollers in a fixed position
- At least one of the second blades is a retractable blade mounted on the other roller by means of a retraction mechanism that allows the retractable blade to be moved between a cutting position in which the retractable blade protrudes radially from the outer surface of the roller to said line of cutting and a retracted position in which the retractable blade is radially retracted from said cutting line.
- the first blades can be two fixed blades arranged axially in respective diagonally opposite peripheral locations of the first rotating roller, while the second blades can be a fixed blade and a retractable blade arranged axially in respective Diagonally opposite peripheral locations of the rotating roller.
- two or more retractable blades of the type described above may also be provided. It is also possible to arrange one or more additional retractable blades in the first cutting cylinder.
- the retraction mechanism may be mounted in an axial recess in the periphery of the roller and comprise a knife holder plate and at least one thrust plate arranged below the knife holder plate.
- the knife holder plate and axially thrust plate are arranged in the axial recess.
- the knife holder plate comprises an emerging part towards the periphery of the roller on which the retractable blade is mounted, an inner surface resting on the thrust plate, and a flexible side wing anchored by its free end portion in the axial recess of the roller.
- the thrust plate is housed in an inner part of the axial cavity and comprises an outer surface that comprises, in an axial direction, a plurality of axial ramps between which two straight support sections are inserted.
- the inner surface of the knife holder plate is provided with recesses configured in addition to the ramps on the outer surface of the thrust plate.
- the thrust plate is axially movable with respect to the knife holder plate between a first position in which the ramps of the thrust plate fit into the recesses of the inner surface of the knife holder plate and the inner surface sits in the support sections on the outer surface of the thrust plate, and a second position in which an initial section of an inclined part of each of the recesses on the inner surface of the knife holder plate is supported on a final section of each ramp on the outer surface of the thrust plate.
- the ramps and recesses are sized so that, when the thrust plate is in said first position, the retractable blade is in said retracted position and, when the thrust plate is in said second position, the retractable blade is found in said cutting position.
- the thrust plate In its displacement from the first to the second position, the thrust plate must overcome the force exerted in the opposite direction by the flexible wing of the knife-holder plate that bends slightly towards the outer periphery of the rotating roller. Due to its flexibility, the side wing recovers its initial position when the thrust plate returns to the first position, so that the flexible wing keeps the knife holder in the retracted position of the retractable blade, so that the retractable blade is retained in that position despite centrifugal forces and Of serious incidents.
- the inner part of the axial cavity is a channel with a bottom located in a first drying plane of the roller, the axial cavity further comprising an anchoring section located in a second drying plane at a distance less distant of the periphery of the roller than the first drying plane, an axial internal step located between said inner part and said anchor section.
- the side wing is anchored in the anchor section, and the thrust plate and the inner surface are located in said channel.
- the knife holder plate may comprise an inner body from which the emerging part emerges.
- the lateral wing extends that inner body that comprises the inner surface of the knife holder plate and is disposed in said channel.
- the knife holder plate may further comprise an axial lateral projection housed in an axial lateral space of the axial cavity extending in said first drying plane towards the periphery of the roller.
- a plurality of guide rods perpendicular to the drying planes and passing through holes in the knife holder plate can be provided.
- These guide rods may comprise at their free ends respective stop elements which prevent, in addition to the axial displacements of the knife holder plate, that the knife holder plate pushes the retractable blade towards a radial position that exceeds the cutting line of the belt cellulose pulp
- the coaxial rotation axes of the rotating rollers are arranged with an angular offset with respect to the cross-sectional line.
- the distance of the transverse cuts of the cellulose pulp web can be adjusted to obtain cellulose pieces of various predetermined lengths, in an efficient manner with a cutting device Simple and reliable structure.
