Description

Continuously operating press

The present invention relates to a kind of continuously operating press, the forcing press is used to produce wood plank or plastic plate, is particularly Fiberboard or particieboard, the forcing press include hydropress frame, and the hydropress frame includes multiple along the longitudinal phase each other of forcing press After arrangement, there is the hydropress frame of upper beam and underbeam respectively, these hydropress frames are surrounded along forcing press Longitudinal extending Heating plate, and the forcing press includes flexible circulation steel band that binder is pulled through to forcing press, and these steel bands are via driving cylinder and turn Guided to cylinder around multiple forcing press upper beams and forcing press underbeam, and via it is turning round together, transported transverse to band with its axis The support component of the rolling of line direction guiding is supported in heating plate, wherein, the compacting gap between steel band can be via multiple It is adjusted transverse to traffic direction hydraulic cylinder disposed adjacent one another respectively between upper beam and upper heating plate, and adds down Hot plate resistance is supported on underbeam by the pressure that hydraulic cylinder applies.

In this forcing press, before glued good particle is processed into plate in the presence of pressure and heat, wherein, heat It is particularly relevant with the cohesive reaction of used glue.

It is known in the forcing press of the type, press power is via application position of the hydraulic cylinder at upper heating plate and under The correspondence position of the bearing of the press power is received at heating plate directly facing face, along the compacting gap with traffic direction extension two Extended in region between individual adjacent application position, and the constriction again in the region of adjacent application position.

Thus, the glue bridge solidified in material to be pressed can be broken again, thus, this extension and subsequent Constriction can cause the undesirable quality of final products to deteriorate.This is particularly in very thin extrusion chipboard or hard fiber board It can be huge shortcoming.

In order to avoid this extension of the press power between adjacent application position, it is proposed that cause by hydraulic cylinder upper plus Stressed application position is applied at hot plate and receives the position of the bearing of the pressure to divide along band traffic direction again at lower heating plate Do not offset one from another.Thus upper heating plate with substantially the same sinusoidal sweep and lower heating plate can be realized relative to that This half of string that staggers is away to cause corresponding sweep to extend parallel to each other and be derived from keeping constant compacting gap. This commonly known as bending function (function) that staggers of sweep.

In order that sweep it is this stagger work, be configured to single type pressure integral with one another for upper beam and underbeam Power machine frame (for example, proposed by the 585A1 of EP 2 514) for, the underbeam and bridge joint of adjacent each hydropress frame Element connects, wherein, these bridging elements are provided with pressure block in centre, and the press power of lower heating plate is received in into these bridge joints In element.

These construction monitorings are got up especially difficult, and thus need to wait, and need in addition as independent component Bridging element, these bridging elements, which must be stabilized to, to be allowed them to receive corresponding power and is delivered to underbeam from side Place.Therefore the component of this stabilization is correspondingly expensive.

Additionally it is known be not single type produce hydropress frame but be provided separately upper beam and underbeam and pass through drawing Upper beam and underbeam are connected to each other by bar.

In such as construction as known to the 258A1 of DE 199 26, hydraulic cylinder be not on heating plate and upper beam it Between but between upper beam and pull bar and therefore upper beam entirely presses to upper heating plate.

Therefore, the construction has as a drawback that：The press power specially matched can not be applied on the whole width of heating plate, Thus can for example to balance different thermal stress and resulting deformation on the whole width of heating plate.

In addition, built for this multi-piece type hydropress frame with the upper beam pushed on the whole relative to pull bar View：Change the width for the underbeam that plate being spaced apart from each other respectively by two, extending parallel to each other is formed, thus to produce bearing Different spacing relative to each other, and thus produce the desired sweep through change.

But this construction also has shortcoming：Corresponding different forcing press machines adjacent to each other must be set in a press Frame.This causes the number of the different structure element of forcing press to increase and therefore not only brings cost disadvantage but also cause phase The installation of forcing press and follow-up maintenance is answered to become difficult.

Therefore, task of the invention is, the forcing press that further exploitation so far discusses above, to cause it to be easier to pacify Dress, and can also be laterally applied to different press powers on production mode reform by the forcing press.

According to the present invention, the task is such as got off solution：Hydropress frame respectively by the upper beam that is connected to each other by pull bar and Underbeam is formed, wherein, underbeam is made up of two parallel plates respectively, and these plates are arranged in outside pull bar in both sides.

Such construction has multiple advantages：Due to eliminating single type hydropress frame, thus can be by frame point Turn up the soil and be fitted into forcing press and split out from forcing press.This not only causes the installation of this forcing press to become easy, but also makes Obtain it and safeguard and also significantly simplify.

Because multiple hydraulic cylinders disposed adjacent one another are supported at upper beam, can additionally realize also in the width of forcing press On reach pressure distribution uniform and according to demand.

Meanwhile the outwardly biased bridging element omitted on each underbeam for each plate for passing through underbeam, it is thus heavier And thus installation and follow-up maintenance corresponding to forcing press when heavy handled component number can reduce.

Additionally show：Because application corresponding same type is made up of upper beam, pull bar and lower beam slab positioned at outside Hydropress frame, the number of the different components of corresponding pressure machine can be reduced, this is played actively for the production cost of forcing press Effect.

In an advantageous manner, underbeam includes two blocks of parallel plates.

Particularly, the plate positioned at outside for forming the underbeam of the bearing to work from below for lower heating plate is arranged to So that they distinguish it is immediately adjacent to one another, wherein, lower heating plate by these plates as caused by press power sinusoidal profile with The profile of upper heating plate staggers half of string away from heating plate is deformed by hydraulic cylinder from top on this.It is achieved in desired bending work( Energy (function), and the compacting gap therefore between heating plate is parallel all the time.

Pressure transverse to the pressure cylinder that traffic direction is arranged in rows substantially along pressure line by being applied to upper heating plate On.

Embodiment is described to provide the other advantages and features of the present invention by following.It is shown in which：

Fig. 1 shows the front view of multi-piece type hydropress frame；

Fig. 2 shows the side view of the subregion of the hydropress frame with three hydropress frames adjacent to each other.

In Fig. 1 it can be seen that the front view of the hydropress frame of continuously operating press.Hydropress frame has upper beam 1 With underbeam 2.The upper beam 1 and underbeam 2 are connected to each other via pull bar 3.

Pull bar 3 is connected to underbeam 2 via bolt 4 and is connected to upper beam 1 via bolt 5.

Upper beam 1 is transversely supported at two top bearing parts 7 of continuously operating press via sliding block 6, and whole Hydropress frame is stood in lower section on pedestal 8.

Press power is produced inside hydropress frame by hydraulic cylinder 9 as caused by forcing press, and these hydraulic cylinders 9 are fixed on At upper beam 1 and it is pressed downwardly onto in heating plate 10.Here, hydraulic cylinder 9 is run substantially in hydropress frame transverse to band Direction 18 is arranged in rows.By pressure caused by hydraulic cylinder 9 from upper heating plate 10 via the support member rolled at upper heating plate Part 11 is passed on the circulation steel band 12 of revolution, and binder 14 is drawn through pressure by the steel band 12 and the steel band 13 to run parallel The compacting gap between two steel bands 12,13 of machine.

Parallel steel band 13 also via it is turning round therewith, with its axis transverse to the support component guided with traffic direction 18 15 support, and these support components 15 roll in lower heating plate 16.

The work for being bonded in the glue included in binder 14 is played in gap is suppressed by temperature caused by heating plate 10,16 With.

Lower heating plate 16 is supported on underbeam 2, thus, thus the press power to be applied by hydraulic cylinder 9 forms bearing 17.

The forcing press with multiple hydropress frames set up side by side each other according to Fig. 1 is illustrated with side view in fig. 2 Subregion.

It can be seen that being configured with the upper beam 1 being made up of corresponding two boards 19,20 and by corresponding two pieces of parallel plates 21,22 structures Into underbeam 2 and the fuel plate 23,24 parallel as two pull bar 3.

The two boards 19,20 of upper beam 1 herein respectively form pull bar 3 two elements 23,24 within and between extend, and And these elements 23,24 again respectively form underbeam 2 two boards 21,22 within and between extend.Thus, underbeam 2 is by two pieces Parallel plate 21,22 is formed, and these plates are arranged in both sides and are located at outside the element 23,24 of pull bar 3.

Therefore, pressure cylinder 9 be fixed on form upper beam 1 positioned at inner side or positioned at centre two boards 19,20 at.Pressure Upper heating plate 10 is pressed downward by power cylinder 9, and herein deforms heating plate.

Bearing 17 on top at edge by be located in both sides the underbeam 2 outside the pull bar 3 that is made up of element 23,24 plate 21, 22 are formed, and bearing 17 is corresponding with the lower heating plate 16 being located at via the bearing 17 on underbeam 2.Because underbeam 2 is parallel by two pieces Plate form, thus Liang2Chu is accordingly separated bearing 17 in each of the lower, and is finally respectively relative to pressure with two part The vertically extending medial axis (being not shown here) of cylinder 9 outwards or on band is run on the hydropress frame in side view Direction 18 is forwardly and rearwardly staggered, to cause two heating plates 10 and 16 to distinguish substantially U-shaped deformation.

Due to adjacent to each other in a press or arrange with following one another along production mode reform or with traffic direction 18 multiple Hydropress frame, thus heating plate 10,16 is placed in the region of each hydropress frame in this U-shaped change curve, its In it is feasible be that necessarily be formed intermediate shape in 10,16 region between these hydropress frames of heating plate, the transition shape Shape corresponds to inverted U-shaped.

Thus, the whole sinusoidal of heating plate 10,16 or the change curve similar to sinusoidal are caused.

It is now important that this sinusoidal change curve negotiating of heating plate 10,16 makes substantially same multi-piece type Hydropress frame is connected to each other to produce, wherein, these hydropress frames are only via only guiding their He of top bearing part 7 Their pedestal 8 is carried to be attached, without being connected by the bridging element for making them be rigidly connected to each other.

Further, since the arrangement for the multiple pressure cylinders 9 adjacent to each other that can be seen that in Fig. 1, thus can have so Possibility：Match compacting gap as needed on the width of forcing press.
