Therefore, the purpose of this utility model is to propose a kind of scraper or scraper stent, and it can farthest make operation or maintenance more safely and install simple.
The purpose of this utility model is achieved by a kind of scraper or scraper stent.
According to the utility model, a kind of scraper or scraper stent for the web of material processing unit (plant) proposed, it has scraper or scraper component, and scraper or scraper component are clamped between the clamping slide block that can move relative to each other and therefore and fix.The clamping slide block can move between final position (Relativendstellungen) at two.At least two are played pressure body same function, that can exert pressure along the direction pretension clamping slide block identical with one of these two relative final positions along force direction.
Propose a solution according to scraper of the present utility model or scraper stent, wherein, on scraper or scraper stent, do not needed to adopt measure independent machinery or structural to guarantee safety operation or security maintenance.Can make thus the structure that scraper or scraper stent are installed keep simple as much as possible.By at least two hose-like pressure bodies that play same function along force direction are set, even so that when one of them hose-like pressure body owing to the crack or when not having sufficient pressure supply to break down, also can make the clamping slide block of releasably clamping scraper or scraper component on relative final position by pretension.So that operation or safeguard safelyr, the safety device of machinery or other are used for keeping or the servicing unit that unclamps scraper or scraper component reserves extra structure space and be no longer necessary for thus.
In addition, be the simple scheme of a kind of technology according to solution of the present utility model, it is robust and cheap.At least two pressure bodies that play same function along force direction are set not to be needed the structure of existing scraper or scraper stent is carried out complexity or expensive coupling; but owing to having dual error protection effect, therefore can obtain reliability and durability scraper or scraper stent.Compare with other operation and maintenance safety measures according to prior art, verified: at least two hose-like pressure bodies that play same function along force direction are set, and not only technology is simple than a pressure body is set, and more economically.
At the utility model and in the thought that therefore this paper comprises all the time, scraper or scraper component refer to scraper plate, scrape sword, scraping cutter bar or any other corresponding elements, these elements are used for being controlled at the thickness of the coating material on removable with respect to blade element or the mobile element, perhaps residue are removed from element.Scraper or scraper component can be configured to hard blade, and arrange with predetermined fixed angle with respect to treating coating or surface to be cleaned; Scraper or scraper component also can be configured to so-called soft blade, and with about treating blade coating or treating that the sharp-pointed especially angle on the surface of scraping arranges.Equally, blade element can be the blade element with the rotation pole of slotting or not slotting.
Preferred Application Areas according to scraper of the present utility model or scraper stent is the apparatus for coating that is coated with for the Paper or cardboard that the form with web is conducted through apparatus for coating.Utilize apparatus for coating to apply coating pigment at web of material.Coating pigment directly can be coated on the web of material that is subject to roller or band supporting for this reason, then utilize blade element to smear evenly (blade coating), perhaps the thickness of coating pigment with needs is coated on the transfer roller, then coating pigment is delivered on the web of material from transfer roller.In addition, also can utilize transfer roller that coating pigment is coated on the web, and by means of blade element coating pigment be adjusted to there the coating layer thickness of setting.
The term coating pigment represents arbitrarily coating material, and it is particularly including coating pigment, sizing agent, pigment, lacquer, waterproofing agent etc.
The Another application field of this scraper or scraper stent is as the support of the scraper component take cleaning as purpose, utilizes this scraper component and/or to be with upper removing coating pigment residue and/or web of material residue from roller.
A kind of preferred embodiment in, at least two sizes that play the hose-like pressure body of same function and its applied pressure along force direction are defined as, even when only having a hose-like pressure body to exert pressure, can realize that also clamping slide block edge is towards the relative motion of the direction in a relative final position.Can guarantee thus to realize dual error protection, even because when a hose-like pressure body breaks down, also can make the relative motion of clamping slide block.At this, preferably to make this still producible relative motion can even arrive relative final position, because like this operation or safeguard and just can carry out safely without restriction.When other all hose-like pressure bodies break down, only a hose-like pressure body that still works just can replace usually at least two functions that the hose-like pressure body is common, thereby scraper or scraper stent only are partial failures, but this can not affect normal operation or maintenance.
A preferred clamping slide block can be mobile between two absolute final positions with respect to another clamping slide block that is fixedly installed.In the case, only need a clamping slide block is embodied as movably, thereby make the structure that scraper or scraper stent are installed keep simple as much as possible.
Preferably make clamping slide block movably by spring element along the direction opposite with the direction of motion in the situation of exerting pressure by pretension.Can obtain extra safety assurance thus, because movably the clamping slide block always is determined the ground pretension along the direction opposite with direction of exerting pressure in absolute final position, and when the pressure body system broke down, removable clamping slide block can not remain on the final position of not expecting or remain on the optional position fully indefinitely under the static load condition.
In a kind of particularly preferred embodiment, the loading position (Belastungsstellung) that relative final position is the clamping slide block, on this position, when at least two hose-like pressure bodies that play same function along force direction were exerted pressure, scraper or scraper component can be by pressure fixing between the clamping slide blocks.In the case, even partial fault appears, namely when a hose-like pressure body breaks down, owing to using at least two hose-like pressure bodies, therefore also can guarantee to continue operation, because scraper or scraper component still can remain between the clamping slide block reliably, and independent mechanical safety device needn't be arranged.Combine with the spring element of relative pretension noted earlier, can realize simultaneously safe maintenance work, because movably the clamping slide block in the situation that spring pre-tightening remained on safely on the unloading position (Entlastungsstellung), thereby can not produce to the attendant risk of extruding.
Alternatively, the final position can also be the unloading position of clamping slide block relatively, at this,, can discharge by clamping slide block fixing scraper or scraper component along exerting pressure towards the direction of unloading position by at least two hose-like pressure bodies that play same function along force direction.These at least two the hose-like pressure bodies that play same function at force direction can be guaranteed safe maintenance, because be exactly the hose-like pressure body of a therein release when breaking down, also the clamping slide block can be remained on the unloading position reliably.Combine with the spring element of relative pretension noted earlier, utilize this mode even can more safely operate, because spring element can remain on the clamping slide block on the loading position reliably, on this position, scraper or scraper component are remained between the clamping slide block safely.
According to the optional embodiment of another kind, be respectively provided to few two hose-like pressure bodies that play same function along force direction, be of use not only on the loading position scraper or scraper component are clamped between the clamping slide block, but also be used for by the clamping slide block along moving to discharge fixing scraper or scraper component towards the unloading position direction.If to being respectively provided to less dual hose-like pressure body to the hose-like pressure body of clamping slide block loading and to the hose-like pressure body that unloads, no matter be that operation or maintenance can both be carried out under the condition of safety then, because all exist fault to substitute (Ausfallersatz) to every kind of situation.Because the function of the hose-like pressure body that breaks down is taken over along the hose-like pressure body that force direction plays same function by another, therefore can reach reliably the loading position of clamping slide block.Equally, by the corresponding redundancy that plays equally the hose-like pressure body of same function along force direction, also can reach reliably the unloading position of clamping slide block.
Preferred at least two hose-like pressure bodies that play same function along force direction arrange directly adjacent to each other, and act on the parts identical, that adjoin with it of scraper or scraper stent.Can make thus the modification that must carry out with respect to prior art scraper or scraper stent few as much as possible, and guarantee simple in structure.
Owing to usually the hose-like pressure body being inserted in scraper or the scraper stent, therefore preferably play the hose-like pressure body of same function in the situation that at least two chambers of formation consist of as a whole with at least two along force direction.In the case, the installation of hose-like pressure body is simple especially.
The total partition wall that one or more definite chambers are divided can define chamber adjacent one another are, and it designs flexibly permission when the pressure drop in the chamber or when losing efficacy, is full of the space of integral body fully by the pressure of another chamber.If the further complementary continuous total tubular section that forms, at least two chambers, then inserting the hose-like pressure body can be simple especially, because the integral body of the hose-like that consists of shows in assembling process as a simpler pressure hose.
Except at least two chambers are arranged each other abreast, in another preferred embodiment, two chambers can also be arranged interlaced with each otherly.Like this, each is positioned at inner partition wall is the form of fexible film, thereby when one of them hose-like pressure body breaks down, another or a plurality of other pressure body can take up space and so bear the function of the pressure body that breaks down.
If further preferred at least one hose-like pressure body that plays same function along force direction has the protuberance that stretches out at the contact-making surface towards the parts of the scraper that adjoins or scraper stent, then especially interference-free realization of the movement of clamping slide block, because the friction between adjacent parts and the pressure body is not directly to occur on the pressure body, but occurs on this protuberance.In addition, be applied to the locational power of protuberance by pressure body and can be directed on the adjacent parts, thereby can avoid the parts run-off the straight that can move relative to each other.
Owing to when breaking down for one at least two hose-like pressure bodies that play same function along force direction, also may relate to the pressure supply, therefore preferably can exert pressure independently at least two hose-like pressure bodies that play same function along force direction.Can realize thus processing safety and the maintenance safe of further improvement.
Except the hose-like pressure body, one or more action bars can also be set, one or more control levers or control lever and/or one or more hydraulic cylinder or pneumatic cylinder perhaps use these elements combinations.Additionally also can use electric controller, for example have the arbor Spindeln of motor or similar assembly).
But first-selected solution is only to use the hose-like pressure body, because usually they are only needed suitably to arrange, can operate and can utilize simple device and control delicately with simple method in simple mode.

The specific embodiment
, in Fig. 5, the parts that function is identical in institute's drawings attached are represented with identical Reference numeral at following Fig. 1.
Figure 1 illustrates the scraper support with scraper edge 2, scraper edge 2 is clamped between two clamping slide blocks 3 and 4 that can move relative to each other with being highlighted, and therefore fixes.
For this reason, scraper support as shown in Figure 1 has supporting member 10, and clamping slide block 4 is arranged on the supporting member 10 regularly.Supporting member 10 for example is the horizontal beam that stretches at the width of web of material to be coated 1 along unshowned apparatus for coating.
Should have clamping section 41 and guide part 5 by fixing clamping slide block 4, guide part 5 has guider 51, this guider 51 is meshed with the ledge of scraper edge 2 in outstanding clamped scraper edge 2, and adjusts the position of scraper edge 2 with respect to roller (not shown) and web of material 1 placed on it.Guide part 5 is provided with regulator 52, is used for the position of accurate adjustment guider 51.The side away from clamping section 41 at fixed clamp slide block 4 is provided with bearing-surface 42.
In addition, fixing clamping slide block 4 also has projection 43, and this projection 43 is extended from the side away from clamping section 41 of fixing clamping slide block 4, and its free end that bends to the L shape has another bearing-surface 44, this bearing-surface 44 is arranged essentially parallel to bearing-surface 42, and formation free space opposite with it.
Movably clamping slide block 3 can be by unshowned device guiding with respect to 4 motions of fixing clamping slide block.This movably clamping slide block 3 have hook-shaped relative clamping section 31, scraper edge 2 and is promptly clamped in its clamping section 41 actings in conjunction towards the surface of inside and fixed clamp slide block 4.
Movably clamping slide block 3 is arranged essentially parallel to 4 extensions of fixing clamping slide block.The part away from relative clamping section 31 at removable clamping slide block 3 is provided with shoulder 32.Shoulder 32 is opposite with the relative clamping section 31 of clamping slide block 3 movably.
Under assembled state, the shoulder 32 of removable clamping slide block 3 tower the free end of projection 43 and fixing clamping slide block 4 away from free space between the end of clamping section 41, that between two bearing- surfaces 42 and 44, form in.The upper surface of shoulder 32 and lower surface be arranged essentially parallel to clamping slide block 4 bearing- surface 42 and 44 with and projection 43.Removable clamping slide block 3 centers on fixing clamping slide block 4 by its clamping section 31 and its shoulder 32.Shoulder 32 will be divided into two free spaces at end and the free space between its projection of fixed clamp slide block 4, wherein insert the pressure hose 6,7,8 and 9 as the hose-like pressure body, and the below also will be elaborated to them.
In each free space that is marked off by shoulder 32, inserted respectively the hose- like pressure body 6,7 of two settings adjacent one another are; 8,9, can be filled with pressure the pressure medium of liquid state or gaseous state to these pressure bodies, be preferably compressed air.
In shown embodiment, the hose- like pressure body 6,7 of per two settings adjacent one another are; 8,9 produce respectively power at Pressure filling, this power pushes away the shoulder 32 of removable clamping slide block 3 bearing- surface 42 or 44 of opposed with it, fixing clamping slide block 4.At this, by the hose- like pressure body 6,7 of setting adjacent one another are; 8,9 power that produce work along identical direction respectively, and act on respectively on the identical assembly of scraper support, thus with the direction pretension of removable clamping slide block 3 edges towards its final position.Therefore removable clamping slide block 3 moves to corresponding final position, and with respect to fixed clamp slide block 4 clamping scraper edge 2 or with its release.
In addition, in shown embodiment, respectively two hose-like pressure bodies are configured to an integral body, this integral body is divided into the chamber of two settings adjacent one another are by total flexible partition wall.As shown in Figure 1, the integral body that is made of these two chambers has the cross section of tubulose, thereby consists of two Room shape pressure hoses.Cross this integral body in the approximately identical situation of the pressure of flexible partition wall in two chambers from the centre.This flexibility partition wall is compared more easily distortion with outer wall, thereby when the pressure drop in one of them chamber or inefficacy, the pressure in another chamber can be full of this whole space fully.
When scraper support was opened, scraper edge 2 was inserted between clamping section 41 and the relative clamping section 31.
For example, if compressed air in addition in the two Room pressure hoses 6,7 that illustrate below in Fig. 1, then this two Room pressure hose 6,7 is attempted the shape of taking surface area as far as possible little with respect to the ratio of volume; In the situation that two Room pressure hoses 6,7, the shape of flexible pipe is close to having the cylindrical of flat side, as shown in Figure 1.Thus by each chamber that expands 6,7 generation power, this power works and jointly shoulder 32 is pushed away bearing-surface 42 along identical direction, stretch with respect to clamping section 41 in this relative clamping section 31 and to draw, and two clamping slide blocks 3,4 are clamped at loading position, wherein, removable clamping slide block 3 moves on the loading position.Like this, scraper edge 2 is sandwiched between two clamping slide blocks 3 and 4 and is fixed.
On the other hand, if compressed air in addition in the two Room pressure hoses 8,9 between the bearing-surface 44 of the projection 43 of the upper surface of the shoulder 32 that inserts removable clamping slide block 3 and fixed clamp slide block 4, then produce the power that is used for unloading or opens scraper support by each chamber 8,9, these power work along identical direction.The chamber 8,9 of two Room pressure hoses 8,9 expansion will be takeed on the bearing-surface 44 that shape part 32 pushes away projection 43 jointly, thereby make removable clamping slide block 3 towards the direction motion in unloading final position.Thus the scraper edge 2 that is fixed is discharged.
If two Room pressure hoses 6,7; 8, the pressure in one of them the chambers 9 is owing to the crack occurring or descend or lost efficacy owing to the pressure supply goes wrong, and the function of the chamber of then breaking down is born by the second Room.Further enlarge under the pressure of flexible partition wall in the second Room, make it in entirely ineffective chamber, be close to two Room pressure hoses 6,7; 8,9 in-profile.In this case, two Room pressure hoses 6,7; 8,9 performances are as the single chamber pressure hose of a routine.Two Room pressure hoses 6,7; 8,9 and be to make second Room of still working bear the function of the chamber of breaking down fully to the size design of chamber applied pressure.
For this reason, in shown embodiment, can apply independent pressure to these two chambers, that is to say from different compressed air sources provides compressed air.Thus so that when one of them compressed air source lost efficacy, also can proceed operation or maintenance.Equally, can between a total compressed air source and chamber, the fault valve be set, when the crack appears in one of them chamber, can utilize this valve to guarantee to provide to another chamber enough pressure.
In Fig. 1, be provided with the device of unshowned spring element, it is the removable clamping slide block 3 of pretension on the unloading final position, therefore only needs to arrange the two Room pressure hoses 6,7 shown in Fig. 1 below, in order to load, namely is used for fixed doctor blade 2.The two Room pressure hoses 8,9 that are used for unloading can omit.
