The specific embodiment
Fig. 1 show see from the end of fluted roller 10 according to fluted roller 10 of the present invention.This fluted roller is designed to be used in the web forming machine to produce vacuum.Fluted roller produces vacuum on that part of width of cloth material of width of cloth material cover tape grooved roller.Web forming machine has a plurality of positions of using according to fluted roller of the present invention.For example can in drying section, be used as slewing rollers, backing roll or paper bowl according to fluted roller of the present invention.In addition, can in press section or forming section, be used as dehydration roll according to fluted roller of the present invention.This roller can be made in very large diameter range.And the width of the degree of depth of regulating tank and neck significantly is to optimize the operation of fluted roller.The groove layer of fluted roller (being disc element) must be made by duroplasts, so that disc element can have required profile.
When the material of disc element was hard, disc element kept self shape.The disc element of being made by hard material accurately keeps self shape.Need accurate dimensions stability, this is owing to after this can cast under stress-free situation, has oversimplified so the manufacturing between framework and the disc element just becomes.Guarantee that with needing soft material the compression casting of sufficient circularity compares, the stress-free casting between framework and the disc element is simpler.
The fluted roller 10 according to the present invention that is shown among Fig. 1 comprises framework 12 and groove layer 14.There is an axle 22 in central authorities at framework 12, and fluted roller is anchored on the framework of web forming machine by axle 22.Groove layer 14 comprises neck layer 16 and bottom 18.From the end of fluted roller 10, neck layer 16 and bottom 18 can be considered a groove layer 14.Dotted line 19 show neck that the groove layer was made of neck layer along vertically comprising of fluted roller and the neck that constitutes by bottom at the bottom of.Come the width of fingerbreadth material forming machine with term " fluted roller vertically " at this.In addition, between framework 12 and groove layer 14, comprise filler component layer 20.The filler component layer makes many kinds of groove layers can be anchored on framework.The selection of material is than freer in the past, thereby can make than lighter in the past fluted roller.In addition, realized simultaneously than more anticorrosive and more wear-resisting in the past structure.
Fig. 2 shows the side view according to fluted roller 10 of the present invention, the not shown section that cuts from fluted roller central authorities.Framework 12 is made of a continuous frame parts, but this framework also can be by constituting along a plurality of longitudinally frame parts of framework.Can come the frame parts of metal in succession by for example Laser Welding.Preferably, framework is made of synthetic material such as carbon fibre.The filler component layer makes groove layer 14 can have the material different with framework 12.Thereby form under the situation of groove layers 14 processing groove 24 according to prior art in the surperficial direct mechanical of framework 12, groove layer 14 and framework 12 are formed by identical materials.Yet what need is that the groove layer has extremely different performances with framework.For example, the disc element that is made of plastics is connected in framework 12, to form groove layer 14.In the groove layer 14 between groove 24 neck 26 is set.
In being shown in the fluted roller of Fig. 2, framework is formed by synthetic material, is preferably formed by carbon fibre.Selection is used for the density of the synthetic material of framework should be less than 2100kg/m 3, preferably less than 1800kg/m 3Use the synthetic material of suitably selecting, be preferably carbon fibre, can be made into band roller groove with desired properties.When machine speed surpasses 2000m/min, will become important unusually such as the main performance of vibrating.The wall thickness of synthetic material is 5-30mm, is preferably 5-25mm.Usually, little, the peculiar frequency of quality is higher and make the less visual advantage of making compound structure of Oscillation Amplitude because of the favorable damping performance.The density that selection is used for the synthetic material of groove layer should be lower than 2000kg/m 3, preferably be lower than 1700kg/m 3Because light, composite construction can also be realized the scheme of non-driving.Because the on-propelled roller obtains the required energy of rotation from fabric, therefore, the quality of on-propelled fluted roller is influential to machine operation.Particularly in accelerator, very heavy on-propelled roller will be oppressed fabric.Usually we can say, according to light grooved of the present invention can make the velocity adaptive operating conditions of fluted roller, than faster and apply littler compressing in the past.In addition, in web forming machine ubiquitous temperature can surpass 100 ℃ and humidity can very high condition under, synthetic material has good resistance.And, the process chemical that in web forming machine, exists fluted roller to resist, for example chloride and alkali lye.Because it is fastening that neck does not come by modes such as for example welding of the prior art, therefore, the present invention can use the framework of synthetic.Except that the plastics synthetic, light-weight metal also is good material because of it is in light weight.The diameter of roller is 400-1000mm, typically 600-900mm.In the application of slewing rollers, diameter can be greater than 1500mm.The width of web forming machine (being the length of roller) for example can be 11m.
The part sectioned view of the fluted roller 10 that Fig. 3 a shows in making the process of fluted roller, see from the side of fluted roller 10.Fluted roller 10 has framework 12 and groove layer 14.Between framework 12 and groove layer 14, comprise filler component layer 20.Use the filler component layer, will be anchored on fluted roller by the square ribbon of extruding formation and fill the part that do not fit between square ribbon and the fluted roller.
Fig. 3 b shows the part sectioned view of the fluted roller of finishing for manufacturing 10, the fluted roller of seeing from the side of fluted roller 10 10.The groove layer 14 of fluted roller 10 is made up of the square ribbon that opens wide.In other words, groove 24 and neck 26 are made up of the square ribbon profile that opens wide that forms by extruding.Therefore, the filler component layer 20 that is included between framework 12 and the groove layer 14 allows frameworks and groove layer to be formed by different materials.
Fig. 4 shows the fluted roller of finishing for manufacturing, the part sectioned view of seeing from the side of fluted roller 10 according to fluted roller of the present invention.Fluted roller comprises disc element.In other words, the groove layer of fluted roller is made up of disc element.Preferably, each disc element 28 comprises bottom 30 and round plate 32.When disc element 28 comprises bottom 30 and round plate 32,, also round plate 32 can be anchored on framework 12, so disc element 28 is carried out fastening very simple owing to become to assign to the bottom 30 of disc element 28 is anchored on framework 12 with filler.Simultaneously, between neck 26, form groove 24.It is very favorable using filler fastening this disc element that becomes to assign to, and this is because after this just need not use independent bracing or strutting arrangement that groove is supported to suitable width in manufacture process.In the prior art, when when coming fastening disc element such as welding, disc element may be out of shape, and is difficult to it fastening in this case.Compare with the method according to this invention, the support of during manufacture disc element being carried out in the prior art has caused extra work.
Fig. 4 shows the fluted roller of finishing for manufacturing 10, the part sectioned view of seeing from the side of fluted roller 10 according to fluted roller 10 of the present invention.The groove layer 14 of fluted roller 10 is made of the independent disc element that forms 28.Separately the disc element that forms is preferably the disc element of independent casting, thereby these disc elements make by using to cast separately such as the compression casting mode, are connected to each other when manufacturing is finished subsequently again.Disc element 28 is connected in framework 12 by the filler component layer of making by casting 20.Casting allows to make the filler component layer with required thickness.The thickness of filler component layer is 2-8mm, is preferably 3-5mm.Although average thickness is greater than 2mm, thickness also can be littler on some points.In this case, the filler component layer can be used for compensating basically the error in the parts that constitute groove layer and framework.In other words, the filler component layer can be eliminated when framework and groove layer link together, the error that produces in the manufacturing of framework and groove layer.Or rather, the filler component layer can be used for making the casting flaw that occurs in the disc element cunning that flattens.
The sign that comprises the size of fluted roller among Fig. 4.The height of the neck layer 16 of fluted roller, promptly groove depth a is 15-112mm, is preferably 20-80mm.The width b of neck is 1.5-5mm, is preferably 2-3mm.Groove width c is 3-8mm, is preferably 4-6mm.The thickness i of bottom 18 is less than half of the height h of groove layer 14, and preferably, the thickness i of bottom 18 is less than 1/3rd of the height h of fluted roller 14.The thickness i of bottom 18 is 3-15mm, is preferably 4-8mm.For example, when the thickness i of bottom 18 was 5mm, size d, e, f and g were following train value.Between wedge structure 42 and groove 24 bottoms is 0.5-2mm apart from d, preferably is about 1mm.Between the inner periphery 50 of wedge structure 42 and disc element is 0.5-2mm apart from e, preferably is about 1mm.The thickness of wedge structure 42 is 2-4mm, preferably is about 3mm.Although wedge structure alignment structures in other words also can have homogeneous thickness, preferably it has the shape that slightly is wedge shape.The unlimited degree on roller surface is 30-90%, is preferably 45-75%.In other words, groove covers the 30-90% on roller surface, preferably covers 45-75%, and neck covers remaining part.Plastics and synthetic as the surfacing of fluted roller should be hard, in order that can be in fluted roller machining go out the groove and the neck of required type.In addition, neck should be a rigidity, even and in use also will not be crooked.For this reason, the material of groove layer should be hard; The groove layer that therefore, can not have deep trouth with for example rubber manufacturing.
The hardness of groove layer, promptly the hardness of disc element is Shore A 80-100, is preferably 88-98.Therefore, can use vinyl esters (vinyl ester), polyester and epoxy resin.Above-mentioned material also can use with reinforcing fiber; Therefore, disc element can be by constituting such as vinyl esters/glass fibre synthetic.
Because synthetic material can make fluted roller have the performance of definite needs, so the groove layer 14 according in the fluted roller of the present invention shown in Fig. 4 is preferably formed by synthetic material.Synthetic material is the general designation of the composition of two or more material, and wherein various materials jointly work, but be not the dissolving or merge.
Shown in Figure 4 according to fluted roller 10 of the present invention in, separately the disc element 28 that forms comprises bottom 30 and round plate 32.Bottom 30 also comprises the wedge structure 42 that is used to make on disc element 28 mutual align axial.Wedge structure needs wedge structure in the manufacturing, because can make the disc element of independent manufacturing can assemble and relative to each other alignment.Alignment with simply but still accurately mode carry out.Therefore, disc element can be stacked on over each other, and their wedge-shaped part is coincide.The hole that is positioned at the center of disc element coincide, and long opening of these disc elements formation, and framework promptly is placed in this long opening.
Wedge structure also makes disc element seal mutually, so founding materials can the height fluidization.When disc element during, between framework and disc element, form the filler component layer around framework.The filler component layer is formed by plastic material (being polymeric material), is preferably formed by epoxy resin.Because epoxy resin is liquid and is easy to fill even minimum hole, so epoxy resin is suitable as the material of filler component layer very much, promptly as founding materials.
Fig. 5 a shows the disc element 28 of the groove layer that is used to form in the fluted roller, this fluted roller in web forming machine in order to produce vacuum.This disc element 28 is the disc element 28 that forms separately.The disc element that forms is continuous vertically separately.The disc element that forms is not made of the interconnective disc element of helically separately.Preferably, the disc element 28 that forms separately comprises bottom 30 and round plate 32.Bottom 30 also comprises the disc element 28 mutual wedge structures 42 that align that are used to make independent formation.
In being manufactured on web forming machine, during in order to vacuum fluted roller, the groove layer is anchored on framework with the filler component layer.Consider the operation and the cost benefit of roller, it is narrow as much as possible and groove is wide as much as possible disc element must to be manufactured neck.
Fig. 5 b shows the disc element of interconnective independent formation.Each disc element that forms separately includes bottom 30 and round plate 32, therefore, when clutch disk member 28, has just directly formed the groove layer 14 of fluted roller.When disc element when the distance of bottom is determined, in the fluted roller that manufacturing is finished, each round plate promptly is in required distance each other.
The bottom 30 that is shown in the disc element 28 of the independent formation among Fig. 5 b comprises the wedge structure 42 that is used to make on disc element 28 mutual align axial.Wedge structure also is sealed disc element, thereby has formed the continuous bottom 31 of neck layer to disc element.Continuous bottom does not allow the liquid founding materials therefrom to pass in large quantities.When forming the continuous bottom of neck layer by wedge structure, make and become simpler.Or rather, in casting process, do not need the tension force of the end flange of this structure during manufacturing.
As mentioned above, the size of the disc element of being made, preferably being made by thermosetting plastic by hard material is highly stable.Because good DIMENSIONAL STABILITY is not so need compression casting.And wedge structure can make the bottom of neck structure tight, prevents that founding materials from passing the bottom.When realizing enough tightnesss, no longer need the tension force of end flange by wedge structure.Manufacturing is not need to use above-mentioned method by the advantage of the fluted roller that the disc element with wedge structure constitutes.
The inner periphery 50 of disc element that is shown in the independent formation of Fig. 5 a comprises alignment protuberance 52.When connecting the disc element 28 that forms separately, alignment protuberance 52 is placed the diverse location (Fig. 5 b) that directly makes progress.After this, during the disc element after framework is placed connection middle, framework is promptly automatically with respect to disc element and centering.Also disc element can be placed on the framework.Disc element can be placed on the framework separately, but the disc element that preferably will link together places on the framework in groups.It is enough that each disc element has an alignment protuberance, but also can have a plurality of alignment protuberances.Preferably, each disc element has the alignment protuberance of equal amount, can use identical die casting disc element like this.The alignment protuberance for example is the hemisphere of the about 5mm of diameter.The hemispheroidal submeter face of splitting is towards above-mentioned inner periphery.Therefore, sphere is just towards framework.Sphere makes framework to push and is assembled disc element in the disc element of slight connection (lightlyconnected) or around framework.Contact area between sphere and the framework is very little, so the filler component layer can not miss the position of align unit significantly.The alignment protuberance also can be other shape, for example square.
The disc element that forms also can be used for forming the helicla flute in the groove layer separately.In this case, disc element covers uniform annulus from framework equally, but the round plate rotation direction.Therefore, disc element radial adaptation relative to each other must accurately be carried out.In a preferred embodiment, round plate in this case, need not to worry to this perpendicular to gimbal axis.
Fig. 6 a shows trough of belt roller stock 11, and the groove layer of trough of belt roller stock 11 is made of the independent disc element that forms 28.Disc element 28 comprises bottom 30, round plate 32 and alignment part 54.This alignment part guarantees that disc element is parallel utterly in casting process.The alignment part that is positioned on the excircle can realize very high accuracy.
Fig. 6 b shows the fluted roller 10 that is produced by the trough of belt roller stock 11 shown in Fig. 6 a, and alignment part 54 (being alignment part layer) has been machined from the surface of trough of belt roller stock 11 and has removed.Alignment part layer can be extremely thin.When removing alignment part, material unaccounted-for (MUF) is very appropriate.Yet, caused the extra work step as the back machining of independent process, but compared that material unaccounted-for (MUF) is very little with milling.Subsequently can be to carrying out machining by the formed neck layer of the disc element of independent casting.
Preferably, the disc element that forms separately is made of round plate and slot part.When round plate did not comprise other entity, the groove layer was directly to form, and does not need follow-up machining.
Available pressuring method is made disc element admirably.Can make by for example transfer modling (transfer molding) or compression molding (compression molding) by the disc element that fiber reinforced materials is made.In transfer modling, with raw material heating and measure out independently in the cylinder, raw material is pressed onto in the mold cavity by this cylinder.In compression molding, raw material in turn measured out in the mould that opens wide and with mould close, make workpiece present the shape of mold cavity by the compression stress of scope between 5Mpa and 25Mpa thus.In compression process, raw material is in liquid state, and this provides the integral body of homogeneity.Therefore, for instance, can in disc element, not produce bubble.
In hot-moulded, utilize hydraulic press that stiffener and resin are molded as final shape in the mould that is heated.Preferably, by SMC raw material or BMC raw material, make disc element by hot-moulded.Thereby, compare with other plastic product, reduced to disc element carry out follow-up finishing needs, make disc element realize high rigidity and low creep, and realized mechanical resistance power and heat resistance preferably.Except that above-mentioned, because in hardening process, die shrinkage (mold shrinkage) only is 0.05%-0.3%, so the most important character of mechanograph is a dimensionally stable.In addition, by applied technology, can form the shape that alignment and sealing property are provided.
Fig. 7 shows the application of fluted roller 10 according to the present invention in bump drying section 40.Because the part at the interval of fluted roller is covered by fabric 34 and width of cloth material 36, so fluted roller 10 and the width of cloth material 36 common vacuum that produce that supported by fabric 34.Obtained reinforcement with the fluted roller 10 common vacuum that produce according to the present invention by flow control apparatus 38.In this embodiment, size as mentioned above even can also can be fluted roller 10 greater than the slewing rollers 44 of 1500mm.Because the king-sized size of slewing rollers 44, the use that the feasible quality that is used as the fluted roller of slewing rollers increases to the on-propelled fluted roller will need to obtain the degree that sizable energy is rotated from fabric, so slewing rollers 44 are driven.
