Description

For the device of processing fiber web

Technical field

The utility model relates to a kind of device for processing fiber web, and it has at least two and maximum three rollers, is configured for the roll gap of processing fiber web between the rolls.

Background technology

Following change is there is in the recent period: their paper products are changed over heat-sensitive paper (thermischen Papieren) and separating tissue from fine paper, newsprint and SC paper due to the change of demand by many paper manufacturers in field of papermaking.Particularly owing to abandoning SC paper (i.e. supercalendered paper), fewer and fewerily need supercalender or glazing calender because that newly increase or form more massive paper mold must less by press polish consumingly.For paper manufacturers, this change has following problem: they cannot re-use existing machine, and this makes the investment dropped into cannot use in the scale expected.

Utility model content

Therefore, the purpose of this utility model realizes a kind of device for processing fiber web, and it is applicable to the paper mold that more often needs in a particular manner and can realizes the use of component or the equipment existed simultaneously.

According to the utility model, this object is realized by feature described herein.

Particularly, the utility model proposes a kind of device for processing fiber web, it has at least two and maximum three rollers, the roll gap processing described fiber web is configured between described roller, it is characterized in that, at least two rollers in described roller are configured to deflection-compensated roll, and at least one roller in described deflection-compensated roll has flexible polymer surfaces, and at least one in described deflection-compensated roll is the used roller of glazing calender.

Preferably, device only has two rollers, and two rollers are configured to deflection-compensated roll.

Preferably, at least one in deflection-compensated roll has the drive unit for rotary actuation deflection-compensated roll.

Preferably, drive unit is configured to belt drives, gear drive, Direct driver etc.

Preferably, at least one roller in deflection-compensated roll has metal surface.

Preferably, at least one roller in deflection-compensated roll is cooled roller.

By will there are at least two and in the roller of the device of maximum three rollers at least two are configured to deflection-compensated roll according to of the present utility model, before can using on the one hand in existing equipment, the roller particularly used in glazing calender or supercalender, these rollers are able to dual-purpose, can be very easy on the other hand and reliably process or process the paper mold more often needed, such as heat-sensitive paper, separating tissue etc.Thus, great amount of cost can be saved when the fiber web processing unit (plant) that Design and manufacture is new.

In order to save cost, advantageously, at least one in deflection-compensated roll is the used roller of glazing calender.

This device a kind of especially simply, embodiment cheap for manufacturing cost is thus that this device only has the roller that two are all constructed to deflection-compensated roll.

In order to realize being easy to paper injection (Papierauff ü hrung) in the roll gap that forms between at least two rollers, at least one can also being arranged in deflection-compensated roll has the drive unit for rotary actuation deflection-compensated roll.

The one of this drive unit is simple and reliable embodiment is that drive unit is constructed to belt drives, gear drive, Direct driver etc.

Can be set in another expedients scheme of the present utility model, at least one in deflection-compensated roll has flexible polymer surfaces.This can realize the surface producing expectation on the fiber web processed by this device.

Same applicable, in another Advantageous embodiments of the present utility model, at least one in deflection-compensated roll has metal surface.

When according in another expedients scheme of device of the present utility model, when at least one in deflection-compensated roll is cooled, can guarantee that the surface temperature of deflection-compensated roll remains in the scope of expectation.

Accompanying drawing explanation

With reference to the accompanying drawings embodiment of the present utility model is schematically described.

Shown in it:

Fig. 1 is the side view according to the device for processing fiber web of the present utility model;

Fig. 2 is by the sectional view according in the deflection-compensated roll of device of the present utility model.

Detailed description of the invention

Fig. 1 illustrates the device 1 for processing fiber web W.This device 1 has at least two and maximum three rollers usually, is configured for the nip N of processing fiber web W between the rolls.In the present case, device 1 has two rollers 2 and 3.Two rollers 2 and 3 are constructed to deflection-compensated roll 2 and 3 respectively, and are placed in known manner on the framework 4 of device 1.

At this, two deflection-compensated roll 2 and 3 are used rollers of unshowned glazing calender.In other words, two deflection-compensated roll 2 and 3 were installed in unshowned glazing calender before being installed in device 1.Obviously, the same glazing calender being once provided with these two deflection-compensated roll 2 and 3 is wherein needed not to be at this this glazing calender.Except two deflection-compensated roll 2 and 3, additionally, also can obtain from such glazing calender the hydraulic component being used for device 1.As required, also drive unit 5 can be obtained from this glazing calender being once provided with these two deflection-compensated roll 2 and 3 wherein.

Preferably, in order to process particularly separating tissue or heat-sensitive paper by press polish, at least one deflection-compensated roll, be that the deflection-compensated roll 2 on top has flexible polymer surfaces 2a in the present case.In contrast, the deflection-compensated roll 3 of bottom has metal surface 3a.Obviously, the position of two deflection-compensated roll 2 and 3 is also commutative, and that is, the roller on top can have metal surface, and the roller of bottom can have polymer surfaces.

Also can learn in FIG, two deflection-compensated roll 2 and 3 have the drive unit 5 for rotary actuation deflection-compensated roll respectively.When fiber web W is introduced into roll gap, for driving the drive unit 5 of corresponding roller 2 or 3 to be constructed to belt drives in the embodiment shown in Fig. 1, but gear drive, Direct driver or similar driving also can be used.

Fig. 2 illustrates the cross section by two deflection-compensated roll 2 or 3.At this, can see each pressure elements 6, it is loaded by pressure medium by pipeline 7, and in known manner for applying pressure to the surface of deflection-compensated roll 2 and/or 3.In addition, the hydraulic pressure feeding mechanism 8 preferably arranged outside deflection-compensated roll 2 and/or 3 can be used for drawing for pipeline 7.Additionally, cooling device 9 is shown in the present case, it is only arranged on deflection-compensated roll 3 place with metal surface 3a, utilizes this cooling device can cool the hydraulic medium being transported to pressure elements 6.In order to remain in the limit of expectation by the surface temperature of deflection-compensated roll 3, preferably cool the deflection-compensated roll 3 with metal surface 3a more strongly than normal conditions.Such as, may need surface temperature to be remained on less than 70 DEG C or even less than 60 DEG C.

Such as, device 1 can be arranged in off-line coating apparatus (Offline-Beschichtungsanlage), to be coated in the coating set on fiber web W before making it.
