Detailed description of the invention
For cooling flat material 2, especially the equipment 1 of (ultra-thin) medium-density plate or (ultra-thin) high density fiberboard, first breadth traffic direction illustrates the roll gap 3 of calibration, then cooling element 4 and its co-operating member 4' on flat material 2 opposite side that multiple successive connects are shown, described cooling element have respectively length be 100mm around with the contact surface 5 of flat material.Co-operating member 4' constructs identical with cooling element 4, so that equipment has multiple module of the same type.Cooling element 4 and co-operating member 4' all have framework 8, and two slewing rollers 6 are bearing in this framework.In this case, contact surface 5 by two slewing rollers 6 around metal tape 7 formed.But alternatively also can consider flexible roller shell.In the inside of framework, be supported with the element 9, the especially clamping element that have cooled, this clamping element can be described below.Each cooling element 4 has at least one unshowned joint for cooling fluid.By cooling fluid to metal tape 7 back to flat material, that is upper cooling in inner side.By this way, the heat from the surf zone of fibrous material distributes through metal tape 7.For this reason, described band has very little thickness, such as, be 0.3mm and be made up of metal, such as steel or better nickel that heat conduction is good.Can monitor the temperature of cooling fluid, and once cooling fluid exceedes temperature limiting in the cooling element 4 of sealing, it is just derived by unshowned discharge line.For making can especially effectively to act on by cooling device 1 of the present utility model, at least 10 cooling elements 4 should connect (for clarity sake only illustrating that four in order to representative in FIG) by successive.As long as metal tape 7 has the surface roughness that Ra is less than 0.8 μm in addition, just can even produce planarization effects again.
Between these cooling elements 4, set temperature compensating basin 10.At this, it is the section for flat material 2, and wherein, it is not therefore actively cooled.If flat material 2 is in temperature-compensating district 10, then heat from the hotter core flow of flat material 2 to not long ago cooled surface.Temperature-compensating district 10 quilt cover 11 covers, to create favourable, moistening, that is environment of adjustable temperature control humidity, does not therefore produce rapid evaporation and therefore do not cause the surface of flat material 2 roughening.The length in temperature-compensating district 10 is 100 to 2000mm, is roughly 900mm in this embodiment.In addition, temperature-compensating district prevents surrounding air condensation on flat material 2 or band 7.Correspondingly, also each band 7 can be surrounded at least in part in the mode of the unknown.
Roll gap 3 is formed by two rollers 12,13.Roller 12 is the roller with cover 15 at this, and this cover 15 can be bent by least one supporting member 14 and regulates and can regulate relative to counter roller 13.By at least one supporting member 14, flat material 2 is also applied in pressure and is correspondingly flattened or calibrates.
Cooling element and the cross section constructing identical co-operating member gained of each inter-working of cutting shown in Figure 2.Cooling flat material 2 between.(compression) element 9 be pressed against around metal tape 7 on, this clamping element 9 is bearing on framework 8.The side facing band 7 of element 9 is provided with region 16.This region 16 supply being designed to groove is in the cooling fluid under pressure, so as between element 9 and band 7 mineralization pressure pad.Thrust also can be produced by the pressure of cooling fluid.In the fringe region of flat material 2, multiple narrow region (groove 16 "), and region (groove 16') may be larger in the middle part of flat material is set.The meaning of this design is, the usually drier or thinner edge of flat material 2 can regulate pressure and cooling more accurately, thus obtains the uniform cross section of flat material 2 subsequently.
Spring 17 is even acting in groove with on hydrostatic contrary direction on edge at this, although to form synovial membrane in extreme circumstances, can get rid of the pressure on the edge of flat material 2 completely.In addition " and the structure of spring 17, adjustable whole cooling element 4 on flat material width that is different that is change, by multiple narrow groove 16 controlled separately through cooling fluid.Therefore, by groove 16', 16 " are obtained different controlled districts 16, can be reacted by this controlled district to each cross section deviation in flat material.
The stereogram of cooling element 4 shown in Figure 3.For understanding better, not shown band 7.By this diagram, declare area/groove 16,16' and 16 " distribution in clamping element 9 better.
Easily can to illustrate with reference to practicable example according to the chart in Fig. 4 by the technical work principle of equipment of the present utility model.This chart temp. displaying function and the relation of cool time.Curve A represents the temperature of the core of flat material 2 at this, and curve B illustrates temperature curve from the teeth outwards.
Flat material is when moment T=0, and in this case, thickness is 3mm, common temperature is 100 DEG C Ultrathin high density fiberboard runs on the first cooling element 4.Surface is cooled to roughly 30 DEG C suddenly by should be the contact of the band 7 of 0.1 to 2mm with thickness.The temperature of cooling fluid (being water in the case) remains on 15 DEG C.
Cooling element 4 and temperature-compensating district 10 so design, and make them live through 500ms respectively with speed 1.8m/s.On the whole, 16 cooling element successive connect.Therefore, be roughly 28 meters by the overall length of equipment of the present utility model.
At the first cooling element, that is leave in the first temperature-compensating district after, the surface temperature on surface is increased to again 65 DEG C.But the temperature of core is declined by heat stream.By after all 16 cooling elements soon, finally evenly turn to 35 DEG C in the scope that the temperature on core and surface is all in 25 to 45 DEG C.Just can cut and flat material described in stacking without the need to the period of storage for cooling thus, and flat material can not become wavy.
