A kind of press section device for light basis weight fluting mediumTechnical field
The present invention relates to a kind of press section device, particularly relate to a kind of press section device for light basis weight fluting medium.
Background technology
Contrasting the squeezing form of the paper machine of traditional fluting medium, press section generally uses the blind-hole roll of delivery type to squeeze,This squeezing is commonly available to the corrugated case paperboard that paper web is the highest, for reaching the corresponding mass dryness fraction of required paper web, generally joinsStandby twice or three road nips are the most.Reach described nip, be commonly equipped with four or the even more pressure roller of the six roots of sensation.In addition, being also equipped with press felt, described press felt is around multiple deflector rolls and together with the described fibrous web formedBeing separated by described press. nips contacting with this fibrous web again and run with loop checking installation, every pressure roller fundamental need is equipped with oneBar annular woollen blanket, meanwhile, also needs to be equipped with properly functioning required woollen blanket cleanings of woollen blanket, correction, tensioning, dry etc. numerous attachedBelong to equipment.Traditional delivery type squeezes due to distant between each nip, is both needed to arrange special drawing between each nipPaper device.
From the foregoing, it will be observed that existing general squeezing form, during for producing the fluting medium of light basis weight, due to floor spaceGreatly, corollary equipment is many, the every operating cost (water, electricity, gas) in significantly adding large user's early investment cost and producingAnd cost of equipment maintenance etc., input and the output ratio of paper plant are greatly improved.
Owing to form the nip that can press dry needed for moisture in limited space, in traditional delivery type squeezing such asFruit needs to form three road nips, then need six roots of sensation roller to match two-by-two, could form required nip.And needed for needing to be equipped with accordinglySix woollen blankets and six overlap corresponding frames, and traditional cloth form of moulting can expend substantial amounts of manpower and time, so every timeShutdown is changed blanket and all can be taken a significant amount of time, thus reduces production efficiency.
Paper injection between conventional nip and nip realizes typically by the special vacuum suction roller arrangement arranged,Owing to vacuum suction roller needs to be equipped with special vacuum pump to realize certain vacuum, so the properly functioning cost to paper plantAnd maintenance cost all has certain consumption.
A kind of four rollers three are had to press technology, although to overcome above-mentioned drawback in actual application to a certain extent, butThe newest or old defect.
