Detailed description of the invention
Schematically illustrate the soft roller 10 of fiber web machine in FIG.This soft roller is furnished with non-rotatable pressure axis and is bearing in pressure shoe on pressure axis, that can load.As its name suggests, this soft roller is furnished with elastic belt cover 13, and this belt housing is arranged around pressure axis 11.Soft roller 10 forms press shoe between which together with counter roller 14, and in order to implement squeezing to fiber web, fiber web is conducted through this press shoe.Press shoe 12 extends substantially on the width of whole long nip press (Langnips, longitudinal nip).Be typically provided with the soft roller of compensate for bend, it is pressed in the circumference of its belt housing relative to soft roller.Above-mentioned pressure shoe 12 is designed to the shape of the cover 15 corresponding to counter roller.Although soft roller is usually located at position above, soft roller 10 is the positions be in below in FIG.Soft roller is also referred to as boots roller.
Fig. 2 shows the shoe press unit observed in the end of roller.The rotation direction of belt housing 13 utilizes arrow to illustrate.Belt shaft 10 on the outlet side being arranged in pressure shoe 12, is provided with rear support device 16 between pressure shoe 12 and pressure axis 11.At this, below rear support device, be provided with independent inclined wedge part.In known technology, inclined wedge part is L shape mostly, at this, the sides adjacent of inclined wedge part may have another inclination pose.When inclination pose changes, the position of rear carrier also can be moved.An independent sliding members 33 is had to be fixed explicitly by with pressure shoe.The task of rear support device be make pressure shoe keep straight, and prevent such as when fiber web by multilayer be delivered in press. nips, pressure shoe is moved along the direct of travel of fiber web.
Rear support device 16 in soft roller is furnished with the sliding members 17 be arranged in pressure shoe, can move for making pressure shoe 12 along loading direction.Figure 2 illustrates loading element 18, it is closely disposed side by side on (Fig. 1) on the route of pressure shoe.Also two loading elements can be set gradually along machine direction.Sliding members 17 is shown showing in Fig. 3 a to Fig. 3 c according to the soft roller of the present invention.By loading element with making being forced property of pressure shoe towards counter roller.Between the cover of roller, fiber web to be squeezed generally remains between two press felt (Pressfilzen) or remains between press felt and counter roller (not shown).At run duration, pressure shoe can less be moved along loading direction, and this makes sliding members licensed.But due to this sliding members, the motion of pressure shoe will be kept sensitive when not pinning.Actual loading element is not shown in Fig. 3 a to Fig. 3 c.Rear support device absorbs the power produced in squeezing process, but the loading of simultaneously authorized pressure boots.According to the present invention, sliding members 17 is constructed to sloped shoulders 19.At this, in the prior art, when two functions are unexpectedly linked together in a same part, inclined wedge part will become unnecessary.Additionally, will easilier than the past realize the supporting of pressure shoe, and compared with in the past, this supporting can produce more simply, it no longer needs high-level machining.
Realized by inclination conversion the adjustment of the pressure curve that the pressing device with long nip press is advanced along machine direction, at this, pressure shoe moves forward and backward along machine direction.Can exert one's influence to the pressure curve of long nip press like this at this: can assign to adjust stress level by the terminal part of the unlifting pressure curve of the standard of load.
In the present invention, sloped shoulders 19 is releasably secured on the outlet edge 20 of pressure shoe.At this, sloped shoulders reliably remains on its position, and conversion of tilting can be realized easily by getting loose of pure pressure shoe.Avoid the machining of the requirement harshness according to prior art in addition.The details of sloped shoulders substantially more easily realizes than on firm pressure axis in pressure shoe.In practice, whole pressure shoe has position in processing machine, and this can be guaranteed by the dimensional accuracy of fixing point and form accuracy simultaneously.Although there is conversion at this, the straight attitude of pressure shoe still can be guaranteed.
According to Fig. 3 a and Fig. 3 b, in order to be produced conversion by the rotation of sloped shoulders 19, sloped shoulders 19 has two different sizes in a machine direction about its fixing point.Show fixing point 21 in figure 3 c, and it is by otch that machining is made in pressure shoe 12.Although there is at this inclination pose used, sloped shoulders is also arranged in pressure shoe by supporting just at this.Meanwhile, power points to sloped shoulders from pressure shoe all the time in the same manner, at this, independently keeps invariable to the supporting of pressure shoe and inclination pose.Sloped shoulders 19 is fixed by multiple bolt 22, and for this reason, sloped shoulders 19 has the hole 23 (Fig. 3 c) for each bolt.
Except novelty and by except the sloped shoulders that arranges unexpectedly, according to rear support device of the present invention also with known different.In the present invention, rear support device 16 is attached troops to a unit rear carrier 24, and this rear carrier is integrated into a part for pressure axis 11.In other words, rear carrier is the fixed part of pressure axis.This is conducive to manufacturing and simplifies the structure of soft roller.More easily realize the straight property of rear carrier simultaneously.In addition be different from prior art, the position of rear carrier will remain unchanged.
In addition, rear support device 16 is attached troops to a unit the sliding members 25 of the abutment face being designed to sloped shoulders 19.Be sliding members and sloped shoulders can be made to form good slip right by the Material selec-tion of sliding members.Such as, sliding members can be made up of the nitrated steel of black, and sloped shoulders can be made up of bronze.By selecting suitable material, even independent sliding members can be given up completely.Sloped shoulders directly contacts with rear carrier at this, and at this, as sliding surface, the foundry goods of machining or can play and acts on (not shown) relatively as such sliding surface.Because rear carrier is integrated, other sliding members standard-sized therefore can be adopted.Sliding members 25 is fixed on rear carrier by bolt 26, that is, be fixed on pressure axis 11 according to the present invention.In the present invention, be arranged on rear carrier to sliding members 25 form fit.In practice, rear carrier is provided with the wedge shape part being integrated into one, and it can prevent the premature motion of the load of sliding members.In the present embodiment, wedge shape part is made up of groove 27, the lug boss 28 of this groove contact slide element 25.Groove and protrude element exactly about forming each other and determining size, stops sliding members along the loading direction of pressure shoe and moving in opposite direction to enable wedge shape part.Mainly only have pulling force to concentrate on bolt simultaneously, and there is no other load.
Because new position and supporting, sloped shoulders can be made up of multiple part continued each other by end.Make the manufacture of sloped shoulders become easy thus, and make storage generally, transport and processing simpler.Correspondingly, sliding members can be made up of the multiple parts being continued each other by end.Because rear carrier and wedge shape part thereof are integrated in pressure axis, even therefore shorter sliding members also can be accurately positioned, and reliably remain on its position.Also can manufacture sloped shoulders blank, cut the part with appropriate length from sloped shoulders blank, so that sloped shoulders is fixed in pressure shoe.In practice, every meter of width of soft roller is provided with the parts of one or two sliding members.At this, the length of the parts of sliding members is 400 to 600mm.
Being arranged in the belt shaft of entrance side of pressure shoe 12, between pressure shoe 12 and pressure axis 11, be provided with the sloped shoulders 29 be positioned on two ends of pressure shoe 12 above.In the present invention, the profile of top rake convex shoulder 29 is consistent with the profile of sloped shoulders 19.Substantially can manufacture the sloped shoulders of a type, it both can be installed as sloped shoulders, also can install as top rake convex shoulder.Again can reduce the quantity of soft roller thus compared to prior art, and conversion of tilting is also simpler than the past.The intensity of structure can be guaranteed simultaneously, and make pressure shoe be in correct pose and noiselessly to work.
In the structure that this is new, conversion of tilting is realized by rotating sloped shoulders.The advantage of new construction is can the straight property of controlled pressure boots better, because compared with prior art decrease the parameter that there is impact and can control it more simply.Integrated rear carrier reduces cost, because the quantity of parts decreases and parts become simpler.Machining also becomes simpler and becomes and is less required simultaneously.This reduces cost.In addition, based on the structure that this is new, the forward support of pressure shoe and rear carrier are arranged on fixing position in a machine direction.In the present invention, rear carrier is integrated in pressure axis.Be alternative in this, only need to utilize bolt 31 to be fixed on pressure axis 11 by the forward support 30 on end.Correspondingly can also fix rear axle.This be also application of shape coordinate form functional wedge shape part.In other words, load can be moved according to shape, which reduces the load on bolt.
Illustrated by separated from one another in figure 3 c according to the parts of soft roller of the present invention.In the present invention, sloped shoulders and top rake convex shoulder rotate about vertical axis when run-off the straight converts.As a rule, in inclination conversion, be positioned at the end guiding the end of the convex shoulder of side to become driving side, vice versa.Although require more machining in this technical scheme, other sides of convex shoulder still may deform, such as, on bottom surface.But compared with the distortion of upper surface, involved protrusion is located slightly different in a machine direction.At this, convex shoulder also can about its longitudinal axis pivotable in inclination conversion.At this, four optional obliquities even can be arrived by convex shoulder.Additionally, different inclination poses can be adopted to adjust the position that can produce the pressure shoe of deviation due to length.
If the formation of the supporting of soft roller and particularly its pressure shoe and manufacture become simpler, then manufacturing cost can reduce compared to prior art.Only be that the constructions cost of every meter of length is just reduced to 1/4th of prior art by integrated rear carrier and simpler sliding members.In addition, the integrated of rear carrier is more convenient for the machining of pressure axis, because control the machining being directly single surface is easier than the surface formed with the wedge-shaped slot of the spaced apart setting of the distance of half meter.Preferably can, according to magnitude classification to machining execution standardization, make structure easier at this.By rear support device according to the present invention can also better than the past, simpler, cost lower realize for pressure shoe more important press shoe straight property.Size than less in the past, and controls than easier in the past.At this, the lateral attitude be different from the past can be provided to select to production equipment not ignoring in cost benefit and functional situation.
