The web of fiber of technical field
The present invention relates to a kind of for transmitting the web of fiber with stable operation, especially paper web, the equipment of board web or tissue webs, wherein first web of fiber is in the first sandwiched area between width output net blanket and width reception net blanket along width operating path, then in transmission stroke, be only in width receives on net blanket, and be then in the second sandwiched area between width reception net blanket and other net blanket, what wherein receive net blanket at width provides fixing upright sucker element on the side of width, described upright sucker element has at least one suction district and have at least one suction district in the region of transmitting stroke in the first sandwiched area.
Background technology
Equipment such as can be used for fibrous material machine, paper machine, board machine or thin-paper machine.
Such as known from WO2009/118449A1 and WO2009/065433A1 for such equipment that web of fiber is sent to other net blanket from a net blanket with fixing upright sucker element.Because fixing upright sucker element causes the wearing and tearing on net blanket, aspirate roller so cannot use when transmitting or aspirate roller as negative pressure equally high when separation drum with using to pick up.At this, negative pressure is usually located p=0.2 to 0.6 at ambient pressure and is clung to.Due to lower negative pressure, in fixing upright sucker element, certainly often do not allow the transmission of web of fiber.Especially edge, may cause width operation problem and tear in machine group subsequently.Therefore, the equipment with fixing upright sucker element known at present also only uses in manufacturing machine very slowly, and under the very high weight per unit area of web of fiber, such as, uses in cardboard.
Summary of the invention
Technical problem to be solved by this invention be exploitation simple, reliable and without wearing and tearing for transmitting and the equipment of stable fibers width, wherein web of fiber is especially guided better on edge, and there is less width operation problem, and however also on net blanket, cause lower wearing and tearing.
This technical problem solves in the following way according to the present invention, namely the stable element be furnished with after upright sucker element on the side of width with convex surface of net blanket is received at width, make jointly to be formed with upright sucker element from the end of the first sandwiched area at least to position A mainly or fully bending width operating path, this position A is in the second section start front, sandwiched area 20mm to 150mm and locates, and preferably 20mm to 100mm locates.Particularly preferably, the convex bending portion of stable element to be connected directly between after the bend of upright sucker element rectilinear path betwixt nowhere.
The obvious shortcoming of the known design according to prior art there is straight or mainly straight transfer path after being sent to width and receiving net blanket.Even if can not reliably prevent edge from holding up with the additional suction on straight stroke, edge pulls and edge flutter.By being mainly bending width guiding section according to of the present invention, especially, when described width guiding section is at least the width guiding section bent completely to position A on transmission stroke, received on net blanket because formed normal force reliably could remain on width by the stable element edge of projection.Experiment show, even if stable element in without suction and negative pressure it also can work.With this, even if higher speed of production can be realized, such as, higher than the speed of production of 1000m/min, and/or under lower web of fiber weight per unit area, such as, be less than 120g/m
2weight per unit area, also use the equipment with fixing upright sucker element without difficulty, and do not occur excessive width operation problem or excessively strong wearing and tearing.For using fixing upright sucker element as unloading substituting of the suction roller of getting breadth, can make investment and spare parts cost very low and make operating cost lower.
Safe distance S between the position A of the end of the width guiding section that mark is bending and the section start of the second sandwiched area is necessary, so that when occurring that web of fiber is damaged or lump, as occurred when operating, neither damage the surface that net blanket does not damage upright sucker element and stable element yet.The length of safe distance S on width traffic direction is chosen as 20mm to 150mm, be preferably 20mm to 100mm, make to provide enough distances between the fixing surface passed through for fibre beakage or caking, and the risk that the edge that simultaneously no longer there is web of fiber on the stroke that this is short may tremble or hold up.In form of implementation known up to now, the rectilinear guide portion transmitting stroke is longer than 1000mm usually, and this causes again obvious width to run interference.
Upright sucker element preferably pivotly and/or can adjust point-blank, makes the position-adjustable of at least one run location and rise.Upright sucker element can be configured to be separated aspirator, namely when web of fiber guides longer stroke between two net blankets and should receive on one of two net blankets.At this, net blanket runs with substantially the same speed.Upright sucker element also can be configured to pick up aspirator, and this is the situation that width is only guided in short-term between two net blankets, so that width is sent to another net blanket from a net blanket.At this, useful and also possible that, width receives net blanket to be had and exports the higher speed of net blanket than width.
The convex surface of stable element is also formed by the bar of multiple lateral arrangement, and main bending width operating path is realized in polygon trend.
For the normal force that will add is applied on web of fiber along the direction of net blanket, stable element also can be configured to can apply with negative pressure.
By the air capacity that lower negative-pressure ward is lower, this setting for ancillary equipment is favourable.For realizing optimum width guiding under more aspiration and low operating cost, can advantageously can set the negative pressure compared at stable element Nei Genggao in the operation of web of fiber at least one suction district of upright sucker element.With this, such as only directly use higher negative pressure when width transmits, and negative pressure only lower in other region just it is enough.
