Continuously operating press

Technical field

This utility model is related to continuously operating press, and this continuously operating press is used for the life of timber or plastic plate Produce, particularly fibre board or board made of particles, this continuously operating press includes：Have tandem multiple on pressing direction Hydropress frame, that is, be respectively provided with the hydropress frame of upper beam and underbeam, and it is around the heating extending along forcing press length direction Plate；Binder is pulled through the circulation steel band of the flexibility of forcing press, steel band passes through drive drum and turns to roller around multiple forcing presses The guiding of upper underbeam, and by turning round with it, supported transverse to the support component of the rolling guiding with traffic direction with its axis By heating plate support, wherein be located at steel band between compacting gap pass through multiple transverse to band traffic direction, upper beam and on plus The hydraulic cylinder being disposed adjacent to each other respectively between hot plate is adjustable, and wherein descends heating plate to resist the pressure applying by hydraulic cylinder And be supported on underbeam.

Background technology

By such forcing press, the granule being scribbled glue before is processed into plate under the influence of pressure and heat, its Middle heat is especially related to the curing reaction of the glue using.

It should be known that in the forcing press of described type, press power pass through hydraulic cylinder the applying position of upper heating plate with Receive the relevant position of bearing of this press power directly relatively at lower heating plate, the compacting gap extending on traffic direction Widen in two adjacent regions applying between position, and narrow in the region of adjacent applying position again.

The glue bridge part thus having cured may disconnection again in material to be pressed, so this broadening and subsequent receipts The narrow quality deterioration leading to undesirable final products.This especially has prominent in very thin compacting chip or hard fiber board Defect.

Apply this broadening between position in order to stop in adjacent press power it is proposed that carrying difference phase on traffic direction Stagger over the ground (biasing) apply position and bearing position, apply to apply in upper heating plate by hydraulic cylinder at positions at these Plus-pressure, at the position of bearing, this pressure to be received by lower heating plate again.Thus achieve upper and lower heating plate with essence The sweep of upper identical sinusoidal shape is mutually staggered half pitch, the extension parallel to each other of so corresponding sweep, and by The compacting gap that this is maintained consistent.This commonly referred to tortuous function that staggers of sweep.

In order to cause this of sweep to stagger, mutual all-in-one-piece integrated pressure machine is configured to for upper beam and underbeam Frame, such as advise in EP 2 514 585 A1, the underbeam of adjacent hydropress frame is connected with bridging element respectively, its Middle bridging element is provided with pressure block in centre, and the pressure of lower heating plate is received in bridging element.

This construction is especially difficult to assemble and wait thus, and needs other bridging element as separation structure Part, these bridging elements must be so stable, to receive corresponding power and can transmit to underbeam in side.This stable Component is correspondingly more expensive.

In addition early it is well known that, hydropress frame can not be integrally manufactured, but upper beam and underbeam separately design and they are logical Cross tie-rod to interconnect.

In construction known in this such as DE 199 26 258 A1, hydraulic cylinder be not located at heating plate and upper beam it Between, and be between upper beam and tie-rod, and using upper beam as overall against the pressing of upper heating plate.

This construction thus has the disadvantage in that, can not apply the press power of specific adaptation on the width of heating plate, with can Compensate different thermal stress for example on the width of heating plate and the deformation thus leading to.

In addition, for this multipart hydropress frame suggestion with the upper beam entirely pushing with respect to pull bar, making The change width of the underbeam that plate that is apart by two respectively, extending parallel to each other forms, with this produce bearing each other not Same distance and the sweep of thus desired change.

This construction but has shortcoming it is simply that different forcing press machine adjacent one another are respectively in forcing press must be designed Frame.This improves the quantity of the different component of forcing press and not only brings cost disadvantage but also increased assembling and corresponding pressure The difficulty of the follow-up maintenance of power machine.

Utility model content

Utility model content task of the present utility model is therefore, and the following continual exploitation of forcing press described above is so as to hold Easy to install and transverse to production mode reform, different pressure are applied to it.

This task is by being resolved according to this utility model it is simply that hydropress frame is mutually connected by by tie-rod respectively The upper underbeam connecing is constituted, and wherein underbeam passes through two parallel-plates compositions respectively, and these parallel-plates are arranged on tie-rod in both sides respectively Outside.

The construction of this mode has multiple advantages：By abandoning the hydropress frame of one, these frames can be in pressure It is installed individually in power machine and dismantle.So not only alleviate the installation of this forcing press, and also simplifies theirs Safeguard.

Because being supported by multiple hydraulic cylinders being disposed adjacent to each other at upper beam, can additionally be accomplished that, in forcing press Width on also obtain pressure distribution that is uniform and suiting the requirements.

Outwards staggered respectively by making each plate of underbeam simultaneously, the bridging element lying on single underbeam can be cancelled, In the installation of relevant pressure machine and follow-up maintenance weight and thus unworkable component quantity is decreased with this.

In addition show, by applying the identical pressure being made up of the plate of upper beam, tie-rod and the underbeam being located at outside respectively Machine frame, decrease the quantity of the different assemblies of relevant pressure machine, its actively impact production cost of forcing press.

In optimal way, underbeam includes two parallel-plates.

Particularly, the lower beam slab positioned at outside constitutes the bearing working from below for lower heating plate, these underbeams Plate is arranged directly next to one another respectively, and the sinusoidal shape profile of the lower heating plate wherein being produced by press power with it is with respect to upper The sinusoidal shape profile of heating plate has staggered half pitch, and on this, heating plate is passed through hydraulic cylinder and deformed from top.Desired folding Qu Gongneng (Schmiegefunction) thus reaches, and the compacting gap between heating plate thus remains parallel.

Pressure is substantially along pressure line, by being applied to transverse to the pressure cylinder with traffic direction setting in a row In upper heating plate.

Brief description

Other advantage of the present utility model and feature are drawn by the description of example below.There is shown with：

Fig. 1 illustrates the front view of multipart hydropress frame

Fig. 2 illustrates the side view with the subregion of the hydropress frame of three hydropress frames adjacent one another are

Specific embodiment

Figure 1 illustrates the hydropress frame of the continuously operating press in front view.Hydropress frame has upper beam 1 With underbeam 2.Upper beam 1 and underbeam 2 are interconnected by tie-rod 3.

Tie-rod 3 is connected in underbeam 2 by bolt 4 and is connected in upper beam 1 by bolt 5.

Upper beam 1 is supported in two top bearing parts 7 of continuously operating press in the horizontal by guide block 6, and whole Hydropress frame is supported on pedestal 8 below.

Produced by hydraulic cylinder 9 in hydropress frame with the press power that forcing press produces, hydraulic cylinder fastens on upper beam 1 And it is downwardly against in heating plate 10.Hydraulic cylinder 9 is in hydropress frame mainly with transverse to the row with traffic direction 18 Setting.The pressure being produced by hydraulic cylinder 9 passes to revolution by the support component 11 that upper heating plate 10 is passed through to roll thereon Circulation steel band 12, this steel band 12 together with the steel band 13 extending in parallel, binder 14 is pulled through between two steel bands 12,13 The compacting gap of forcing press.

Parallel steel band 13 passes through turn round together, its axis transverse to the support component guiding with traffic direction 18 15 Support, these support components roll in lower heating plate 16.

Lead to the solidification suppressing the glue containing in binder 14 in gap by the temperature that heating plate 10,16 produces.

Lower heating plate 16 is supported on underbeam 2, and such bearing 17 forms the press power being applied by hydraulic cylinder 9.

It is the forcing press with the adjacent multiple hydropress frames stood illustrating in side-looking according to Fig. 1 in fig. 2 Subregion.

As can be seen that not only upper beam 1 is to be made up of respectively two parallel-plates 19,20, underbeam 2 is also parallel by two respectively Plate 21,22 is constituted, and two parallel planar elements 23,24 also implemented into by tie-rod 3.

Two plates 19,20 of upper beam 1 respectively constitute tie-rod 3 two elements 23,24 within, between extend, and its Again constitute underbeam 2 two plates 21,22 within, between extend.Underbeam 2 is thus made up of two parallel-plates 21,22, two Parallel-plate is arranged in both sides outside the element 23,24 of tie-rod 3 respectively.

The so internally positioned or middle respectively plate 19,20 constituting upper beam 1 is fixed with pressure cylinder 9.Pressure cylinder will Upper heating plate 10 is pressed downward, and so that its here is deformed.

Bearing 17 is by plate 21,22 edge on top of the underbeam 2 outside being located at, in both sides, the tie-rod 3 being made up of element 23,24 Place is formed, and this bearing 17 is corresponding with the lower heating plate 16 being located on underbeam 2 via this bearing.Because underbeam 2 is by two parallel-plates Constitute, Liang2Chu correspondingly separates bearing 17 in each of the lower, and is finally respectively relative to capwise with two part The axis of (not shown here) pressure cylinder 9-in side view with regard to hydropress frame-outwards and-run with regard to conveyer belt Direction 18- forwardly and rearwardly staggers (biasing), and two such heating plate 10 and 16 is respectively deformed into basic U-shaped.

Because multiple hydropress frames are adjacent one another are in a press or along production mode reform or carry traffic direction 18 each other Arrange in front and back, (Verlauf, change is bent to make heating plate 10,16 be placed in this U-shaped trend in the region of each hydropress frame Line), wherein feasible is that region between hydropress frame for the heating plate 10,16 necessarily be formed intermediate shape, this transition shape Shape is correspondingly inverse u-shaped.

The trend doing so used in heating plate 10,16 is overall sinusoidal shape or near sinusoidal.

It is important that now, this sinusoidal shape of heating plate 10,16 moves towards by essentially identical multiple piece pressure The mutual arrangement of machine frame produces, and wherein these hydropress frames are only by only guiding their top bearing part 7 and support Their pedestal 8 connects, rather than is attached by the bridging element making them be rigidly connected to each other.

In addition, based on multiple pressure cylinders 9 shown in FIG setting adjacent one another are, can be on the width of forcing press Adjust compacting gap on demand.
