Description
Technical field
It the utility model is related to print field, more particularly to a kind of printing machine drier.
Background technology
In press drying device can help the solvent in ink to volatilize, and accelerate ink solidification, for preventing printing from gluing
Dirty and adhesion, raising print speed printing speed, raising print quality are significant.The principle of various drying devices is different, and structure is also different.
But more and more faster with the speed of modern printing machine, the technological deficiency of printing machine drying device gradually exposes, including：To reduce life
Speed is produced to exchange drying effect for, production efficiency greatly reduces；Paid no attention to the drying effect for reducing speed of production to exchange for
Think, printing pollution is more serious.It is uneven heated to directly result in after stock dried particularly with than relatively thin stock
Occur shrinking uneven, curling, buckling phenomena, had a strong impact on stock surface smoothness and its quality of production.
In Chinese patent literature disclosed " a kind of printing machine drying device ", its notification number is CN205395429U, public
It is on 07 27th, 2016 to accuse day, and this application case discloses a kind of printing machine drying device, including：One roll wheel assembly, one along
The conveyer belt that roll wheel assembly is set, is additionally provided with some rollers above the conveyer belt, the roller and the conveyer belt it
Between leave for printing to be dried movement space, the conveyer belt outer surface contacts with printing to be dried；One above roller
Injection apparatus, by injection apparatus discharge high temperature gas flow spray to printing to be dried, the utility model can reach uniform, efficient
Feature.The weak point of the utility model is that drying device space-consuming is big.
Utility model content
The utility model is in order to overcome deficiency of the prior art, there is provided a kind of production efficiency is high, paper surface is smooth
The printing machine drier spend, to occupy little space.
To achieve these goals, the utility model uses following technical scheme：
A kind of printing machine drier, including some feeding-in rolls and dry net, some feeding-in rolls are formed in sagittal plane
One polygon, the center of polygon are provided with drying cylinder, and two adjacent feeding-in roll sides in some feeding-in rolls are respectively set
Have air roll, dry net enters between a pair of air rolls and feeding-in roll, is transmitted via each feeding-in roll, from another pair air roll and
Sent out between feeding-in roll.Paper after printing enters drier, is dried by drying cylinder, and the moisture of evaporation is by the drying below paper
Net absorbs, and is then sent out from drier, is cooled down, cut, the process such as folding.Dry net uses network structure, can
So that more moisture are directly entered air by dry net, it is appropriate to alleviate the difference of paper both sides and intermediate moisture, and then subtract
Difference in few Paper Moisture distribution.By some feeding-in rolls sagittal plane formed a polygonized structure can greatly reduce it is dry
The space that dry mechanism takes.
If preferably, being provided with dry hole in described paper feeding roller surface, described feeding-in roll one end is provided with feeding-in roll
In air discharge vavuum pump.Paper is close on dry net by feeding-in roll absorption so that and paper is not subject to extra-stress,
Prevent disconnected paper phenomenon from occurring.
Preferably, being covered with around some described feeding-in rolls makes described printing machine drier be incubated closed vapour
Cover, air exhausting device and air supply device are provided with described vapour cover.The use of dry net improves the evaporation efficiency of drier
Many, set vapour cover and air draft, air supply device structure effectively can discharge steam to reduce the humidity of drier, prevent
Only reduce drier evaporation capacity because the mass transfer pressure differential of evaporation reduces, so as to improve drier drying capacity.
Preferably, it is provided with heat exchanger between described air exhausting device and air supply device.Air supply device is used for heat
Wind introduces drying section to balance the air quantity from the discharge of vapour cover, and avoids producing condensation.What the overwhelming majority was discharged by steam
The energy of dry paper is included in the steam of discharge and taken away by vapour cover, and the hot and humid gas discharged by heat exchanger, which preheat, to be supplied
Wind air can reclaim most heat energy.
Preferably, described dry net is made up of synthetic fibers.Synthetic fibers have that air permeability is high, wear-resisting, heat-resisting, anti-ization
The advantages that learning corrosion, improve the performance of dry net.
Therefore, the utility model has the advantages that：
1st, some feeding-in rolls are formed into a polygonized structure in sagittal plane, drier occupancy can be greatly reduced
Space；
2nd, the evaporation efficiency of drier is improved using dry net；
3rd, the hot and humid gas discharged by heat exchanger, which preheat air feed air, can reclaim most heat energy, save energy
Source, environmental protection.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, feeding-in roll, 2, dry net, 3, drying cylinder, 4, air roll, 5, vapour cover, 6, air supply device, 7, air exhausting device.
Embodiment
Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made more specifically
It is bright.
As shown in figure 1, a kind of printing machine drier, including six roots of sensation feeding-in roll 1, dry net 2 and vapour cover 5, six roots of sensation paper feeding
Roller 1 forms a regular hexagon in sagittal plane, and the center of regular hexagon is provided with drying cylinder 3, and two in six roots of sensation feeding-in roll 1 are adjacent
The side of feeding-in roll 1 be each provided with air roll 4, be available for paper and dry net 2 logical between air roll 4 and corresponding feeding-in roll 1
