Description
Technical field
The utility model relates to a kind of device for the treatment of fiber web.The utility model particularly relates to a kind of device for the treatment of fiber web by applying treated substance on the surface at least one of fiber web, the device that should apply treated substance on the surface at least one of fiber web treated substance can be applied directly to web at least one on the surface.
The utility model is specifically related to a kind of device for the treatment of fiber web by applying treated substance on the surface at least one of fiber web, and described device comprises: two rollers, formation processing nip between described roller; For applying the instrument of treated substance; The beam that can move, supports described for applying the instrument of treated substance; And the instrument for making beam move.
Background technology
From prior art, the manufacturing technique of fiber web typically comprises the assembly be made up of multiple equipment that production line is arranged continuously.Typical production or process line comprise head box, wet end and press section, and drying section subsequently and reel machine.Produce process line and can also comprise other device for finishing fiber web material and part, such as sizing applicator, calender, coating part.At this description with in the claims of enclosing, fiber web refers to such as paper web and board web.
In the production of fiber web (such as paper web and board web), the applying glue sizing substances be used to by adding such as glue chemicals changes the attribute of fiber web.In top sizing, sizing substances directly or via the roller of the dry end at fiber web machine is added on the surface of fiber web.The applying glue of paper web and board web typically uses independent sizing applicator.About sizing applicator, in the arrangement of prior art, use various different application techniques, such as, expect pond applying glue (pond sizing) technology or film transfer techniques or spray application techniques.
Fiber web grade through being coated with and coating become more and more welcome, are therefore increasing the demand of coating process and equipment.In coating, especially in pigment application, coating station before it is dried makes the surface of web fiber be formed with one deck coating color (coating substance).The process of coating can be divided into and to be fed to by coating color on its surface (this be called as apply coating color), and the final quantity of adjustment coating color.The coating of paper web and board web typically uses apparatus for coating---coating machine.About coating machine, in the arrangement of prior art, use various different coating technique, such as material pool technology or film transfer techniques or spraying technology.
In sizing applicator and coating machine, applying glue/applicator roll is used to be expressed in web by treated substance in the nip formed between by these rollers, and guides fiber web by this nip.In the spraying technology based on sizing applicator and coating machine, Spray painting tool is positioned at movable beam or corresponding movable supporting construction.Typically, moving through of beam makes beam motion provide by actuator (such as servomotor).Beam moves with the crooked route around corresponding roller on gear ring.Beam is furnished with two support wheels, and guides along guiding piece, or guides accordingly with a crooked route corresponding to the periphery of respective rollers, thus between the moving period of beam, and the constant distance on beam and roller surface.This distance is very little, is about 5mm, actual upper beam therefore almost with the surface contact of roller.A kind of so known arrangement is disclosed in FI patent disclosure 122319B, comprise for by the first applicator device on the first side of treated substance paint fiber web with for by the second applicator device on the second side of treated substance paint fiber web in this arrangement, form press. nips at two squeezing Tool Rooms, after applying treated substance, fiber web is through this nip.This arrangement also comprises the telecontrol equipment at least making applicator device follow the movement path on the surface of squeezing instrument.
In order to the instrument being kept for applying treated substance runs aptly, in some interim, beam needs clean.When needing to change applying glue/applicator roll owing to wearing and tearing or need to change the grade of the fiber web that will produce due to the demand of different brackets, dissimilar roller may be needed, such as guarantee the infiltration of desired treated substance, or the maneuverability that fiber web is good.
In the known arrangement changed for roller, guiding piece or the corresponding instrument of the wheel of brace summer must be separated, and beam must be left the surface of roller by lifting block or corresponding tool into rotation, and this can lose time, and also can make complex structure.
In known arrangement, the clean difficulty of beam and complicated, because the surface of beam distance roller is constant and closely, therefore clean space is very limited, this even may hinder suitable clean or damage roller, and this may cause needs to shift to an earlier date more roll change conversely.
