Embodiment
More detailed description the present invention is carried out below in conjunction with accompanying drawing.
Referring to Fig. 1, the overall structure schematic diagram of three-dimensional pressure cotton machine is shown.Three-dimensional pressure cotton machine has three groups of pressure rollers, is respectively first group of pressure roller, 1, second group of pressure roller 2 and the 3rd group of pressure roller 3.Should be appreciated that, although what illustrate for exemplary purposes in this figure is three groups of pressure rollers, the pressure roller group number of reality can change, such as four groups or more groups, such as, also has other pressure roller group after the 3rd group of pressure roller shown in this Fig. 1.The upper lower compression roller group of each group has independently driving mechanism 4, so that manufacturing speed is poor between each group pressure roller and between upper lower compression roller.Or velocity contrast also can use common or that part is common driving mechanism, adopts different gear ratio to reach by different transmission rigs.Top also has upper and lower roller space setting device 5.
Feature of the present invention is to have employed fancy pressure roller in pressure roller group.As seen in Figure 3, fancy pressure roller has outstanding pressure roller sheet 7 and pressure roller groove therebetween.Show the embodiment that pressure roller sheet trend is identical with rock wool traffic direction in this Fig. 3, but should be appreciated that, actual pressure roller sheet trend can also be angled with rock wool traffic direction, is even interconnected to form overall helicitic texture.
Width between the pressure roller sheet of above-mentioned fancy pressure roller and pressure roller groove is than generally between 1:1-1.5.Two adjacent fancy pressure rollers can be engaged mutually, as shown in Figure 2.In other cases, two fancy pressure rollers are not engaged, such as, when screw-type pressure roller, or fancy pressure roller and ordinary light face pressure roller mutual alternate intervals when.
During compacting rock wool, the rock wool layer completed enters from first group of pressure roller.The upper pressure roller group upwards opened with certain angle of first group of pressure roller, to receive loose rock wool layer.First group of pressure roller does not generally adopt fancy pressure roller, because the effect of fancy pressure roller and surperficial rock wool layer can not be delivered to inside by loose rock wool layer, can not realize object of the present invention.But also can adopt fancy pressure roller in several pressure rollers rear of first group of pressure roller.
First group and all there is velocity contrast between second group and the upper lower compression roller of the 3rd group, and the positive-negative relationship of velocity contrast is mutually contrary.Such as barrel velocity difference v about first group
1for when positive, namely on first group barrel velocity faster than lower compression roller, then about second group barrel velocity difference v
2be negative, namely barrel velocity is slower than lower compression roller on second group, and lower compression roller difference v on the 3rd group
3for just.When velocity contrast, original different rock wool layers entering pressure cotton machine start to move with different speed, when entering first group of pressure roller effect under, it is faster than bottom rock wool layer that top rock wool layer moves, but when moving to second group of pressure roller, bottom rock wool layer is faster than top rock wool layer again, to the 3rd group of pressure roller, top rock wool layer is faster than bottom rock wool layer again, so causes each rock wool layer in distortion, is formed pleating.
Prior art pleating only has rock wool layer moving towards in the horizontal direction and changes, and does not have direct interaction, thus can not form three-dimensional bridging arrangement between different rock wool layer.Second group to the 3rd group pressure roller of pressure cotton machine of the present invention adopts fancy pressure roller, as seen in Figure 1.When rock wool layer contacts with fancy pressure roller, pressure roller sheet contacts with rock wool layer, and pressure roller groove can not, therefore the velocity contrast between the different piece causing same rock wool layer, in this layer, velocity contrast inwardly transmits step by step, particularly under the existence of fold, causes overall in layer destruction, and overlap between form layers, form three-dimensional connection.Interlayer connection makes whole rock wool product formation entirety, strengthens integral rigidity, makes the performance enhancement of product.Fig. 4 illustrates the section of the rock wool product that the pleating technology of prior art manufactures, and as seen from the figure, although fluctuating gauffer appears in rock wool layer, the relation between each layer still keeps complete, and interlayer relation is not strong.Fig. 5 is the rock wool product adopting pressure cotton machine of the present invention to manufacture, and as can be seen from the figure, the connection relation between each layer greatly strengthens, and whole product becomes an entirety.
By reference to the accompanying drawings embodiments of the present invention are described in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, can also make a variety of changes under the prerequisite not departing from present inventive concept.
