Description
Technical field
The utility model is related to paper product manufacture and processing technique field, specially a kind of anti-broken hole vacuum furnace.
Background technology
The major function of press section of a paper machine is to be dehydrated, solidify page, while improve page characteristic, improve wet web strength with
Improve the drying capacity of drying section.Wherein, vacuum furnace is the key equipment for realizing press section major function, and it is widely used in making
The wet end and press section of paper machine, is the critical elements of wet end dehydration, and the quality of wet end dehydration is directly connected to production cost
Just.
Being mainly characterized by of vacuum furnace has the less through hole of many diameters on roller shell, through hole runs through roller shell, roller shell during work
Inner chamber maintains continuous vacuum.When page and woollen blanket or towel enter the nip of pressure roller and vacuum furnace, the water in page proceeds to hair
Blanket or towel.When the water saturation in woollen blanket or towel, under pull of vacuum effect, water is discharged from woollen blanket or towel, is entered
Through hole, imports and discharged after roller shell inner chamber.But in water absorption course, paper also can be inhaled inward accordingly, sometimes result in paper and inhaled
Enter excessively and broken hole.
Utility model content
The purpose of this utility model is to provide a kind of anti-broken hole vacuum furnace, and the paper for possessing the transmission of guard vacuum roller is not fragile
Damage, solve the problems, such as paper broken hole during blotting.
For achieving the above object, the utility model provides following technical scheme：
A kind of anti-broken hole vacuum furnace, including the cylindrical roll body of a vacuum, are roll body shell outside the roll body, institute
State and be provided with roll body vacuum chamber, the roll body shell is provided with large through-hole arranged in a straight line, between the roll body shell and vacuum chamber
Roll body inner casing is provided with, the roll body outer side is fixed with rubber layer, and the rubber layer includes primer layer and face glue-line, described
Face glue-line is also set by shell in connecting rod fixing roller body in the top of primer layer, the roll body shell both sides on the roll body inner casing
There is small through hole arranged in a straight line, the large through-hole arranged in a straight line on the roll body shell is mutual with the small through hole arranged in a straight line of roll body inner casing
Stagger.
Preferably, the thickness of the rubber layer is 20-30mm, and wherein primer layer thickness is 5 to 10mm, the thickness of face glue-line
For 15 to 20mm.
Preferably, the large through-hole internal diameter arranged in a straight line on the roll body shell is 3.5mm, arranged in a straight line on roll body inner casing
The 2.7mm of small through hole.
Preferably, in the rubber layer large through-hole phase arranged in a straight line on primer layer and face glue-line perforate and roll body shell
Even.
Compared with prior art, the beneficial effects of the utility model are as follows：By being fixedly installed one in roll body inside the shell
Roll body inner casing cuts the through hole of roll body inner casing and the mutual dislocation of roll body shell, it is ensured that paper has stop in water absorption course, no
Can rupture.
