The invention is characterized in that the holding device comprises at least one cloth (8) that wraps around the pressure body at least in sections and allows the deformation of the pressure body, said cloth holding the pressure body in a position perpendicular to the pressing direction, said position being fixed relative to the support and/or counter-element during the deformation of the pressure body. The invention further relates to a pressing arrangement, a doctor blade, guide or scraper device, and a suction roll for a paper, cardboard, or tissue machine having a press-on unit according to the invention.
Description
The present invention relates to a kind of by claim 1 compressing unit that is used for paper machine, board machine or tissue machine as described in the preamble.
In paper machine, board machine or tissue machine, for example in pressing device, use compressing unit pressing against on the pair roller around the roller shell of press shoe.In addition, for example in the sealing device of suction roll, use compressing unit, so that will be used for the roller shell that the sealing lath of the sealing device of sealing superpressure district, relative peripheral region or low-pressure area presses against perforation.In addition, compressing unit uses in Pulp scraping device, guiding device or scraper, for example is installed on the mating surface that is provided by roller so that will scrape slurry element, guide element or scraper element by this compressing unit.
At this, generally include the pressure body that at least one is designed to the local deformable at least of pressure hose or force pipe by the known compressing unit of prior art, it comprises that at least one can add the cavity of pressure fluid.This pressure body is bearing on the supporting member and becomes on the direction at co-operating member greatly when the pressure fluid that adds its cavity increases or reduces with respect to original state or dwindle, and applies a thrust that relative original state is greater or lesser thus on co-operating member.
This by prior art known pressure style as have the sulfuration finished straight pin, remain in a certain position by relative supporting member of this pressure body of this straight pin and/or co-operating member.In addition, known by prior art, by guiding face fixing, that for example form is the U-shaped section bar pressure body is remained in a certain position.
In having the pressure body that vulcanizes finished straight pin, especially through regular meeting leakage loss takes place in the transitional region between straight pin and pressure body case surface.When by the time, observe the wearing and tearing that the pressure body outer surface that contacts with guiding face has aggravation usually with the guiding face of pressure body adjacency guiding pressure body.In addition, constitute these guiding faces that pressure body is remained in a certain position when it is out of shape expends usually very much.
Therefore, technical problem to be solved by this invention is, a kind of compressing unit that comprises at least one deformable pressure body is provided, wherein, can one or more pressure bodies is remained in a certain position than known pressure body.
This technical problem is by a kind of paper machine that is used for, the compressing unit of board machine or tissue machine solves, this compressing unit has a supporting member and a co-operating member and at least one and is arranged between supporting member and the co-operating member, at least the pressure body of local deformable and a holding device, pressure body comprises that at least one can add the cavity of pressure fluid, wherein, pressure body is bearing on the supporting member and becomes greatly or dwindle along pushing direction when the pressure fluid that adds its cavity increases or reduces with respect to original state, and on co-operating member, apply a thrust that relative original state is greater or lesser thus, pressure body relative supporting member and/or co-operating member when it is out of shape are remained on the definite position by holding device.
Be characterised in that by compressing unit of the present invention holding device comprises that one locally at least holds weaving cotton cloth of at least one pressure body and authorized pressure body deformability, this is weaved cotton cloth pressure body is remained on when it is out of shape in the definite position.
By in the solution of the present invention, deformable pressure body is held weaving cotton cloth of pressure body and authorized pressure body deformability and is fixed in a certain position by local at least.Thus, on the one hand no longer need to make pressure body for example be fixed on the supporting member and the straight pin sulfuration that remains in a certain position is worked in the pressure body.Can cancel on the other hand the abrasion pressure body, be used to guide and/or the guiding face of support pressure body.
In each dependent claims, provide each favourable design of the present invention and expansion design.
Pressure body is preferably perpendicular to be pushed direction and remains on a certain position.This means, do not allow it to move perpendicular to pushing direction when pressure body is out of shape, that is, for example the authorized pressure body does not move along machine vertical (MD) and/or transverse machine (CMD) when it is out of shape.
Preferred described at least one pressure body overwhelming majority is weaved cotton cloth by described at least one and is held.If pressure body for example has vertically and circumferencial direction, so advantageously, pressure body by weaving cotton cloth at least partly, holds on its circumferencial direction especially substantially.At this, vertically be the maximum sized direction of pressure body.
A kind of preferred design regulation of the present invention is weaved cotton cloth and is arranged on regularly on supporting member and/or the co-operating member for described at least one.In this case, weave cotton cloth and fixedly connected with supporting member and/or co-operating member.Weave cotton cloth to be connected this can be direct.Another kind of design regulation of the present invention is weaved cotton cloth to be parallel to and is pushed direction and guide movably.
For example can consider that holding device also comprises at least one and the lath of weaving cotton cloth and fixedlying connected, weave cotton cloth to be arranged on supporting member and/or the co-operating member regularly or to be parallel to and push direction and guide movably by this lath.If pressure body has vertically, so described at least one lath is especially along the longitudinal extension of pressure body.
To push direction and guide pressure body movably in order to be parallel to, the guiding device of described at least one lath of guiding when pressure body is out of shape for example can be set.Guiding device can comprise and one or morely be fixedly placed on supporting member or the co-operating member and guide pins that stretch out from supporting member or co-operating member and have the perforation corresponding with guide pins one or more laths that described at least one lath can be along these perforation guidings when pressure body is out of shape at this.
Can consider that equally described at least one pressure body is only held by unique weaving cotton cloth or described at least one pressure body is weaved cotton cloth by polylith holds, these arranged in succession of weaving cotton cloth are holding on the direction.
Weave cotton cloth to design and have the end for described at least one, promptly have two opposed end section, or Endless.
A kind of specific design scheme regulation of the present invention, weave cotton cloth have two end section and described at least one pressure body holds like this by weaving cotton cloth on its circumferencial direction for described at least one, make two end section point to the side-prominent and be connected of lath with lath at pressure body.
If for example only be provided with one and weave cotton cloth, but be provided with the pressure body of a plurality of arranged in succession, so a plurality of pressure bodies can be weaved cotton cloth by this part jointly and be held at least partly.
