Accompanying drawing of the present invention is as follows:
Fig. 1 is for making according to the principles of the present invention and the side sectional drawing of the extended position cramping machine that turns round.
Fig. 2 is the vertical cross section figure that is got along line II-II of Fig. 1.
Shown in each figure, forcing press has the jaws N that slip W passes through therein and accepts felt f from the water of slip extrusion
1And f
2Device.Jaws is defined between pressure roll 10 and the endless belt 11.When normal slip enters folder mouthful N, when the part of contact zones 11 looping pressure rolls 10 by cramping.Water from the slip extrusion enters felt f
1And f
2Each felt is annular, it enter again jaws before this by a felt drying machine.In some cases, may wish only to provide a felt such as f
2Silver was touch roll 10 and one of was broken away from the side scaler under roller divides this moment.Also can omit felt f
2And make slip with felt f
1Enter jaws, at this moment then carry slip under 11 minutes in the disengaging side of jaws.In this kind structure, can be desirable to provide the pressure roll 10 that has on the outer surface various grooves, be easy to enter felt and each groove to assist slip extrusion water and water.
Therefore, the folder degree of lip-rounding is formed in first element of roller shell 10 and is with between 11 second element.Be given shape axle 17 in the band, axle also has basically along the direction extension of traversing machine fills up the size of being with 11 inside.Axle has its shape surface, recessed top 18 of the peripheral shape of laminate pressure roller 10 basically.Therefore, when slip enters jaws N, in the distance that holds pressure roll by band, be applied in a uniform pressure basically.
Do not apply clamping force in the device of jaws, this device comprises that form is the supporting arrangement of roller shell 19.The surface below 20 of axle is recessed into and the shape of the backing roll 19 of fitting basically.Two ends 26 of axle and 27 are divided into thick or big than the middle part, so axle and band are maintained in the position between each roller.Axle can along machine direction move freely and only traverse machine direction be limited mobile, so axle and band can be located automatically with respect to jaws.
Be provided with to make and be with device lubricated when stationary spindle moves, for reaching this purpose, petroleum pipeline 29 and 29 is connected in the interior path of axle 30 and 31.Each path has the oilhole that suitably distributes along on its total length, thus oil by uniformly dispersing on the width of machine and retainer belt on axle by continuously lubricious.Certainly, axle processes smooth surface, the friction when sliding thereon to reduce band.
As shown in Figure 2, be provided with and make axle traverse the end frame 31a that locatees on the machine direction, allow that axle is in the automatic setting movement along machine direction thereby end frame is smooth at it.Be provided with prevent that oil from carrying and axle between the sealing 32 and 33 of regional seepage, oil can be without interruption a certain amount of through the sealing oil spill to replace through managing 28 and 29.
The preferably, below backing roll 19 is preferably established a deflection control device as upper rolls.Upper rolls is a roller shell, and inside has the slip hoof 12 of garden convex surface, and oil is held in the roller shell, thereby sets up the dynamic lubricating oil of skim between the inner surface of hoof 12 and roller shell 10.But hoof is installed on the oscillating roller pin 13 that traverses machine direction, and this pin is supported on the top of the piston 15 that is positioned at cylinder 15a.Cylinder 15a is supplied the oil of pressure through supply pipe 16.
Backing roll shell 19 supports skim oil is being arranged to keep a forming dynamic oil film between roller shell and the hoof on the roller shell inner surface equally with the slip hydraulic bearing hoof 21 that is engaged in roller shell inner surface.Hoof is supported by the roller pin 27a on the piston 23.Piston is installed in through supply pipe 25 and is supplied with in the cylinder 24 of pressure oil.
Shown in configuration under, two roller shells are all by the pressure fluids supporting in cylinder 15a and 24, so when the liquid when being in pressure under applies a uniform pressure along roller length, the roller shell will be fair directly and not crooked along jaws.This can prevent that any bending stress in roller or slip hoof 12 and 18 from causing in the end or the center produces extra pressure, and this extra pressure can make the end of jaws and the pressure between the center inhomogeneous.
In some structure, may wish to economize except the deflection control device in one of roller shell and with this roller and make the traditional type solid roll of overhang bracket on axle.This kind situation will cause along folder mouthful generation crooked, but in some operation, this kind situation can not have obstruction.
Because hoof and band are located in jaws automatically, so system turns round with balance mode, do not have because parasitism or instantaneous pressure due to the stress on the material betide in the jaws.In addition, owing to structure simply reduces manufacturing cost.
Shown in configuration tie up in the horizontal level and operate, should understand, the folder mouth can be made vertical direction configuration slip and then move down to enter folder mouthful or move up and enter the folder mouth that upwards rotates.
If when needing dual cramping operation, also can make slip on deflector roll, oppositely move through the jaws that is formed at backing roll 19 and is with 11, in such cases, another felt that adds is passed through this jaws.
Because oil is completely cut off in impervious band and is not arrived chance on the slip, so structure can provide the slip of cleaning more reliably.Band also can be the 4th, 238,287 or 4,229 for known in this area and be used for the structure of various extended position cramping machines, the material that No. 254 United States Patent (USP) discloses and illustrates.
In the running,, and slip is moved in the folder mouthful, preferably prop up roller and all rotated by drive though the driving effect one of can only be added in two rollers roller.When slip enters jaws, pressure be added in be with 11 and pressure roll 10 between, and slip is accepted except water pressure holding in the All Time of path at roller 10 places by 11.The clamping force mat of folder mouth is added on the power of roller 10 and applies, and the power that roller 19 applied reaches in the face of the band portion of folder mouthful N and is transmitted through its surperficial and mobile band portion of contact, axle.Lubricant is made band move freely in axle by the surface of continuous feed-in axle and interband, and axle is for can automatically locating.Since the shape on surface on the jaws of axle have substantially with roller 10 outside surperficial identical radius or profile, so through the uniformity substantially of the pressure in the stroke of jaws, and produce differential pressure can predisposition along the variant position of jaws not sending out flecition or other power at slip.And because the jaws line is straight shape traversing machine direction, and each roller shell all is held in straight shape by the side direction control device in it, so the flecition that does not have owing to axle causes unequal power to produce unequal pressure.
Therefore, improved extended position cramping function provided by the invention reaches aforementioned objects and advantages of the present invention and the good effect of dewatering can be provided in paper machine.
