Description
Technical field
The present invention relates to a kind of device that forms extended nip between collaborative roller and shoe roll, this device is used to handle web-shaped product.
Background technology
Known, this equipment that has shoe roll has press section, is used to handle web-shaped product, in particular for the dehydration and/or the press polish of paper web.DE3317455 has disclosed a kind of press apparatus that is used for the paper web dehydration, and wherein, the flexible roller shell of tubulose is around the fixed support element operation that is configured to hollow frame.By pressure shoe, roller shell can be crushed on the circumferential section of cooperation roller, in this way, forms an extended nip that extends in the direction of motion of roller shell.For tensioning roller shell vertically, its each end all is fixed on the rotating wheel disc.The latter rests on the bearer ring through anti-friction bearing, and bearer ring rests on the bearing sleeve, so it can move vertically, and can not rotate.This bearing sleeve is fixed on the support component.The compression spring influences bearer ring and outwards moves, thereby influences the tensioning of roller shell.
In order to improve the life-span of roller shell, also know from EP0527881B1, after the specific operation cycle, roller shell relative pressure boots are moved vertically.So moving is enough to make the axial marginal zone of each tired district of roller shell away from pressure shoe.At the stiff end place of roller shell, roller shell is moved, and the other end of roller shell is located automatically, and therefore follows moving axially of roller shell stiff end place automatically.Move with the add ons of roller shell tensioning and realize by the integrated cylinder of form.Add ons not only pins down project organization, and needs additional maintenance work.
Summary of the invention
Therefore the purpose of this invention is to provide a kind of as described in the preamble, device of being used to form extended nip as claimed in claim 1, it does not have add ons, in order to improve the life-span of roller shell, to allow roller shell tensioning vertically and moves.
This purpose realizes by the characteristics of claim 1 characteristic.
In this way, provide a kind of device that is used to form extended nip, wherein the inside of wheel disc is configured to the cylinder/piston unit.By the pressure medium supply, can like this, wheel disc be moved to balancing gate pit's supply pressure medium of two moving cylinder/piston unit.The tensioning of roller shell and can be that the same functional unit of block head cylinder/piston unit is realized by form with respect to moving axially of pressure shoe.
In this case, the piston in the cylinder/piston unit can form by the radial extension of bearing sleeve, and cylinder can form by the doughnut in the bearer ring simultaneously.Pressure pipeline is introduced in the balancing gate pit aptly via piston, and this is in order to gather favourable pressure medium flow.By the cylinder/piston unit, roller shell move can be in discontinuous step or any desired position carry out.
In order to pin fixedly wheel disc, provide a kind of additional locking means.
For the damping purpose, also in order to brake moving of roller shell, the design bearer ring is so that they can overcome spring prestressing force and move.
The mobile route that is positioned at the bearer ring of roller shell outside can be sealed by bellows.Therefore, reduced pollution, also meaned to have reduced maintenance cost.
From following specification and appending claims as can be seen the present invention further improve.

The specific embodiment
The present invention relates to a kind of device that forms extended nip between shoe roll 1 and driven cooperation roller 2, two rollers interact in extended nip 3, are used to handle web-shaped product, particularly paper web, and this device may become the part of paper machine room.
Shoe roll 1 comprises fixed support 4 and roller shell 5, and roller shell 5 can rotate around support 4, and is made by flexible material, for example rubber or plastics.Roller shell 5 is configured to the form of flexible pipe, and its two ends are fixed on the wheel disc 6,7 of rotary setting on the support 4, thereby forms the shoe roll 1 of sealing.In order to keep cylindrical shape, preferably compressed air is supplied with in the gap between support 4 and roller shell 58.
A pressure shoe 9 is provided on support 4, and it limits extended nip 3 with cooperation roller 2.Pressure shoe 9 supported bars are supported on the support 4, and this support bar comprises the hydraulic pressure support component 10 that arrange many spaces vertically.
Shown in Fig. 2 and 3, bearer ring 17,18 is installed on the bearing sleeve 19,20 that is fixed on the support component 4, and so they can move vertically.In this case, each all forms axially two moving cylinder/piston unit bearer ring 17,18 and bearing sleeve 19,20, its balancing gate pit 21,22 is connected with 27,28 with pressure pipeline 25,26 with 23,24, therefore when exerting pressure medium, it can make bearer ring 17,18 move vertically relative to bearing sleeve 19,20.
Under any circumstance, bearing sleeve 19,20 all forms the piston 29,30 that radially extends, it keeps apart two balancing gate pits 21,22 and 23,24, and preferably the pressure pipeline 25,26 and 27,28 along horizontal expansion ends at balancing gate pit 21,22 and 23,24 through it.In addition, pressure medium chamber 31,32 can form in bearing sleeve 19,20.Piston 29,30 and doughnut 33,34 interact, and under any circumstance, doughnut all is formed on the bearer ring 17,18, forms two balancing gate pits 21,22 and 23,24 in doughnut respectively.
By optionally exerting pressure medium in balancing gate pit 21,22 and 23,24, roller shell 5 can be tensioned and also can move vertically.
In order to form fixing wheel disc 6, a locking device can additionally be provided, according to Fig. 2, this locking device is formed by locking device 35, and for example, it locks in discontinuous step with lock ear and lock tube and moves.Selectively, can provide locking in any desired position.
Also can preferably provide spring 36,37, with respect to frame 13,14 at spring prestressing force lower supporting bearing ring 17,18.The mobile influence that is subjected to damping of bearer ring 17,18, and finally be limited.
According to Fig. 1, the structure of cooperation roller 2 as usual and is rotated through bearing 38,39 and is installed on the frame 13,14.
As Fig. 4 diagram, the difference of second exemplary embodiments of the present invention and above-mentioned exemplary embodiments is that bearer ring 17,18 and frame 13,14 under any circumstance all connect through overlapping 38, and cover 38 can be flexible as accordion.Correspondingly, cover 38 forms bellows, and it can move with bearer ring 17,18, and in this course, covers mobile route.Thereby avoided pollutant sediment on the mobile route on the bearing sleeve 19,20.The spring 36,37 that can form extension spring or compression spring has also obtained extra protection.
For example DE3317455 or EP0527881 are described, when make axle sleeve in the axial direction during tensioning with other modes, can guarantee to overlap 38 purposes and function equally.
