Description
Technical field
The present invention relates to a kind of speed lifting methods of paper superpressure process.
Background technique
It is processed from paper pulp after becoming paper, it is also necessary to superpressure processing is carried out to paper by multiple roll superpressure machine, in order to provide
Flatness, tightness of paper etc., in the prior art, processing method routinely, superpressure processing need to expend the more time, reduce
Yield.
Summary of the invention
The present invention increases at drying cylinder according to the above deficiency, provide a kind of speed lifting method of paper superpressure process
Manage step.
The technical scheme is that
A kind of speed lifting method of paper superpressure process, includes the following steps:
Finished product roll paper is placed on superpressure unreeling machine by S1, and superpressure unreeling machine starts to raise speed；
The paper exported on S2 superpressure unreeling machine is sent to multiple roll superpressure machine and carries out multistage superpressure, and multiple roll superpressure machine follows superpressure to put
The speed-raising of volume machine；
S3 carries out trimming to paper；
S4 paper enters the drying of drying cylinder machine；
S5 paper enters cooling cylinder machine room temperature cooling；
The paper that S6 cooling cylinder comes out enters calender press polish processing, and calender follows superpressure unreeling machine and multiple roll superpressure machine to raise speed；
S7 paper on-line checking；
The winding of S8 paper superpressure.
In step S2, the roller quantity of multiple roll superpressure machine is 5-15.
In multiple roll superpressure machine raising speed or down speeding procedure, after step s 3 before step S4, increase by the first spraying wet machine
It squirts in advance, promotes Paper Moisture 0.3-2%.
It after step s4 before step S5, is squirted after increasing by the second spraying wet machine, promotes Paper Moisture 0.3-2%.
Preferably, the temperature of drying is 70-110 DEG C when the drying.
In step S6, the quantity of cooling cylinder is 1-4, and cooling cylinder temperature is at 15-35 DEG C.
In step S7, the on-line checking includes quantitative, moisture and sick paper.
If moisture evaporation at normal temperature is not filled it should be noted that present invention speed during superpressure is promoted
Point, the moisture content index of paper certainly will be influenced whether, for this purpose, increasing drying cylinder machine baking step, but since calender, superpressure unreel
Machine and multiple roll superpressure machine are heavy equipment, and the big inertia of quality is also big, and when speed-raising needs gradually to accelerate, in the superpressure that is near completion
When need gradually to slow down, in addition, to be kept substantially constant temperature constant for the temperature of drying cylinder machine, therefore, gradually accelerating and gradually slowing down
During, because of drying time lengthening so that the moisture content of paper declines, paper meeting embrittlement hardens the water content of paper, influences
To the quality of paper, in order to solve the technical problem, the first spraying wet machine of increase squirts in advance squirts process with after the second spraying wet machine, finally
The quality of roll paper can be made to be consistent on the whole.
It should also be noted that, the present invention, which squirts, can be effectively improved paper curling, and on the one hand cooling cylinder effect reduces paper
Temperature, while being condensate in the water on cylinder face by outside air, improve the water content of paper, then pass through calender raising paper
Tightness and smoothness, and the electrostatic of paper is reduced, cooling cylinder can also be substantially reduced the consumption of thermal energy；
It should be noted that the building top surface above spraying apparatus can generate obviously during squirting and squirting in advance
Condensing drip, water droplet is dripped will affect the quality of paper on paper, in order to solve the technical problem, pre- squirt and sprays described
In wet process, the building roof that spraying apparatus is placed is provided with multiple domes being arranged side by side, further includes:
Exhaust duct is fixed on the lower section of multiple domes one end and offers on a side wall, exhaust duct multiple
Exhaust outlet, the length direction of the wind direction alignment domes of exhaust outlet, exhaust duct is through the air blower outside air inlet pipeline communication chamber；
Exhaust fan is located at the lower section of multiple domes other ends and is fixed on another side wall；
Exhaust duct can blow out the moisture that spraying apparatus generates along domes, and outdoor is discharged through exhaust fan.
The air blower connects hot air source, and the hot air source dehumidifies through dehumidifier.
It should be noted that advantage there are two domes, first, the area for increasing roof has dispersed vapor and has not allowed
Easily form water droplet, second, the wind that exhaust outlet is sent out is influenced by domes, and the flow direction of air-flow is not easy at random, and vapor is advantageous
In uniform discharge.
The domes are the structure on the roof of the building.The technical solution just designs before being suitble to house to build
Good drawing.
Domes are the building decoration materials being fixed below building roof.The technical solution is suitble to traditional workshop
Transformation.
Pipe ventilated area of the exhaust duct close to air inlet pipeline position is greater than exhaust duct far from air inlet pipeline position
The pipe ventilated area set.
The present invention has structure beneficial effect that is simple, at low cost, energy saving, improving yield.
