Description
Technical field
It the utility model is related to a kind of sheet production equipment, more particularly to a kind of novel coating machine.
Background technology
Piece feeding roller of coating machine generally use, it is according to certain linear resonance surface velocity and certain coating content, coating is equal
Even is applied on base material, then dries the base material for scribbling coating by heat drying device, then carries out obtaining coating after cold, rewetting equal
Even, surface-brightening coated article.But following problem in production at present be present：
（One）Base material is completed to be directly entered baking oven after coating, because oven temperature is generally 120 ~ 160 DEG C of high temperature,
The coating rate of drying of base material is fast, but substrate surface easily produces conjunctiva；
（Two）In the larger production environment of air humidity, base material during coating easily taking by contact aqueous vapor, base material
Entering baking oven with aqueous vapor can make the coating generation of base material vaporific；
（Three）Because the humidity of residing production environment is different, during rewetting cool down the rewetting of uncontrollable base material and
The humidity of production environment is consistent, and base material humidity is too high or too low all to make base material deform, crimp or fold.
Three of the above problem all directly affects the product quality of substrate coating.
The content of the invention
Problem to be solved in the utility model is to provide a kind of novel coating machine, and this novel coating machine can not only be prevented
Only base material produces conjunctiva and vaporific during heat is dried, moreover it is possible to keeps base material to keep balancing each other with production environment when cooling down rewetting
Humidity, the product quality of the substrate coating of guarantee.The technical scheme of use is as follows：
A kind of novel coating machine, including feeding roller, nip rolls, drying tunnel, chill roll and wind-up roll, feeding roller, drying tunnel, cooling
Roller and wind-up roll are set gradually along sheet material conveying direction, and nip rolls is engaged with feeding roller, it is characterised in that：Also include nature
Rewetting mechanism, natural rewetting mechanism are arranged between the chill roll and wind-up roll, and natural rewetting mechanism and ambient atmosphere
Communicate；The drying tunnel includes low temperature drying tunnel and high temperature drying tunnel, and low temperature drying tunnel is close to the feeding roller, and high temperature drying tunnel is close to cooling
Roller, dehydrating unit and exhaust outlet are provided with low temperature drying tunnel.
Above-mentioned natural rewetting mechanism communicates with ambient atmosphere refers to that the natural rewetting mechanism can be kept with ambient atmosphere
Identical humidity, can be that the natural rewetting mechanism is sent into the natural rewetting mechanism or referred to ambient atmosphere
In the place communicated with ambient atmosphere.
Drying tunnel is divided into low temperature drying tunnel and high temperature drying tunnel, base material carries out being introduced into low temperature drying tunnel, low temperature drying tunnel after coating
First carry out preliminary heat to base material to dry, the dehydrating unit in low temperature drying tunnel is removed the aqueous vapor of base material and arranged by exhaust outlet
Go out, prevent base material from being produced because of aqueous vapor on coating vaporific；Base material enters back into high temperature drying tunnel after preliminary heat is dried and is dehumidified,
Now the Temperature Difference Ratio between the base material after low temperature drying tunnel and high temperature drying tunnel is directly entered between high temperature drying tunnel after completing coating
The temperature difference it is much smaller, can prevent substrate coating produce conjunctiva.
When base material through overheat dry, cooling after before being wound, by nature rewetting mechanism carry out rewetting；Due to returning naturally
Wet mechanism communicates with ambient atmosphere, and natural rewetting mechanism can keep identical humidity with ambient atmosphere, and base material by returning naturally
Wet mechanism can fully be contacted with ambient atmosphere, make the humidity of base material relatively flat with ambient atmosphere humidity before being wound
Weighing apparatus, it can prevent that base material deforms in winding.
As preferred scheme of the present utility model, the temperature of the low temperature drying tunnel is the 1/3 ~ 1/ of the high temperature drying tunnel temperature
2.It is 120 ~ 160 DEG C that the heat of usual base material, which dries temperature, by the temperature setting of low temperature drying tunnel is high temperature drying tunnel temperature 1/3 ~ 1/2,
Make coating surface rate of drying slower, and there is more preferable effect on moisture extraction.
As preferred scheme of the present utility model, the natural rewetting mechanism includes at least a floating jockey pulley and Duo Gen
Support roller；Floating jockey pulley is arranged between more support rollers.Because during natural rewetting, the humidity of sheet material is with outer
The change of boundary atmospheric humidity, so as to cause the tension force of sheet material in natural rewetting mechanism everywhere different, by more support rollers it
Between floating jockey pulley is set, be capable of the tension force of adjustment control sheet material.
As the further preferred scheme of the utility model, length of the sheet material Jing Guo nature rewetting mechanism is at least
30m.To ensure rewetting effect, sheet material is set to be contacted in natural rewetting mechanism with ambient atmosphere more abundant, sheet material passes through certainly
The length of right rewetting mechanism is at least 30m, when ensureing finally to be wound by nature rewetting mechanism the humidity of sheet material with
Ambient atmosphere is consistent.
The utility model compared with prior art, has the following advantages that：
Drying tunnel is arranged to low temperature drying tunnel and high temperature drying tunnel by the utility model novel coating machine, and sets up nature rewetting machine
Structure, the dehydrating unit in low temperature drying tunnel are removed to the aqueous vapor of base material and discharged by exhaust outlet, prevent base material because aqueous vapor
And produced on coating vaporific, while the temperature difference between sheet material and high temperature drying tunnel is reduced, can prevent that substrate coating from producing conjunctiva,
Rewetting is carried out by the natural rewetting mechanism communicated with ambient atmosphere again afterwards, can fully be contacted, made with ambient atmosphere
The humidity of base material, with ambient atmosphere humidity relative equilibrium, can prevent that base material deforms in winding before being wound.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
