Working principle:
As shown in Figure 1, cladding nonwoven cloth material 100 and lower layer's hot-wind nonwoven cloth 101 are delivered to the progress of heat seal device 102
It bonds, obtaining composite material may be selected to apply one layer of glue (preferably not applying) and be rotated with the first transfer wheel 105 with identical speed,
Apply one layer of glue after being laid with the first filler and to its surface；
It is glued as shown in Figure 1, upper nonwoven cloth material 113 and upper layer hot-wind nonwoven cloth 112 are delivered to heat seal device 111
It closes, obtains composite material and obtain composite material one layer of glue (preferably not applying) of optional application and with the second transfer wheel 108 with phase
It is rotated with speed, be laid with after the first filler and one layer of glue is applied to its surface.
As shown in Figure 1, the cladding non-woven fabrics 100 is wider than through coating unit after lower composite layer and upper composite layer are compound
The side edge part of lower hot-wind nonwoven cloth 101 and upper composite layer is continuously turned back by coating unit 115 along the material direction, so that
The compound core body is coated in the two sides by the cladding non-woven fabrics 100.
Between upper nonwoven cloth material 113 and upper layer hot-wind nonwoven cloth 112 and lower hot-wind nonwoven cloth 101 and cladding non-woven fabrics
Macromolecule between 100 fills principle: the upper layer hot-wind nonwoven cloth 112 and lower 101 density of hot-wind nonwoven cloth used is smaller, between having
Gap understands some high molecular material 203 and drains to nonwoven down so macromolecule is sprayed at 112 surface of upper layer hot-wind nonwoven cloth
Between 112 material of cloth material 113 and upper layer hot-wind nonwoven cloth, likewise, some high molecular material 203 drains to lower heat down
Between wind non-woven fabrics 101 and cladding non-woven fabrics 100.
As shown in Figure 1, the compound core body after the cladding of two sides carries out hot pressing to its diversion channel slot through hot-press arrangement 116, under making
The diversion channel slot 202 of composite layer and upper composite layer bond it is stronger, guarantee imbibition after do not separate, do not rise and stick together.
It should be appreciated that described above, the specific embodiments are only for explaining the present invention, is not intended to limit the present invention.By
The obvious changes or variations that spirit of the invention is extended out are still in the protection scope of this invention.
