Device.
Present inventors appreciate that in printing technology, ink layer is filled on transfer roller, then printing ink transfer to roller
The upper layer of ink so that roller oils have and be left white, paper makes have what is be left white in roller by the extruding of roller and hard bottom roller
Ink layer is transferred on paper, can form localised application structure smooth, of the same size.Inspired by this, present invention
If people is coated in the preparation of barrier film, it is realized that printing technology is converted into non-all standing formula, can solve above-mentioned prior art
Present in problem, form localised application structure smooth, of the same size.
As depicted in figs. 1 and 2, the preparation facilities of a kind of non-all standing formula coating barrier film according to embodiments of the present invention, bag
Include：Transfer roller, resilient roller, hard bottom roller 300.
Specifically, the surface of the resilient roller has and is left white, and the resilient roller rolls with the transfer roller to be coordinated.
Hard bottom roller 300 rolls with the resilient roller to be coordinated.Advantageously, hard bottom roller 300 can be vulcanie bottom
Roller or metal bottom roller.
As shown in figure 1, when the transfer roller is anilox roll 110, the resilient roller is the convex print that surface has salient point 211
Roller 210.Advantageously, salient point 211 corrodes to be formed using photosensitive resin, or salient point 211 is formed using rubber laser engraving.This
When, the surface of block roller 210 is left white as the part positioned at salient point below 211.
Advantageously, the preparation facilities of described non-all standing formula coating barrier film also includes hopper 400, hopper 400 and reticulate pattern
Roller 210 is connected.
As shown in Fig. 2 when the transfer roller is smooth roll 120, the resilient roller is the gravure that surface has groove 221
Roller 220.Advantageously, groove 221 corrodes to be formed using photosensitive resin, or groove 221 is formed using rubber laser engraving.Now,
The surface of gravure printing roller 220 is left white as the part beyond groove 221.
Advantageously, the preparation facilities of described non-all standing formula coating barrier film also includes flushing roller 600 or gap scraper
700, flushing roller 600 or gap scraper 700 and smooth roll 120 are combined.
The preparation technology of non-all standing formula coating barrier film according to embodiments of the present invention, comprises the following steps：
Transfer roller is driven to roll, so that the surface of transfer roller forms adhesive film；
Make resilient roller roll with transfer roller to coordinate, so that adhesive film is transferred to the non-blank space of resilient roll surface；
Extruding by the barrier film of pre- coated nano ceramic material by resilient roller and hard bottom roller, makes on resilient roll surface
Adhesive film is transferred to the surface of barrier film, forms localised application structure smooth, of the same size.
More specifically, when the transfer roller is anilox roll 110, the resilient roller is the convex print that surface has salient point 211
Roller 210.Driving anilox roll 110 rolls, so that the surface of anilox roll 110 forms adhesive film.Make block roller 210 and anilox roll
110 roll cooperation, so that adhesive film is transferred on the salient point 211 on the surface of block roller 210, and the surface of block roller 210 is located at
Part (i.e. the blank space of block roller 210) of the salient point below 211 does not have adhesive film then.By pre- coated nano ceramic material every
Film 500 makes the adhesive film on the salient point 211 on the surface of block roller 210 by the extruding of block roller 210 and hard bottom roller 300
The surface of barrier film 500 is transferred to, forms localised application structure smooth, of the same size.Such a mode, suitable for adhesive film thickness
Relatively thin situation.
In other words, using anilox roll material transfer structure, one layer of uniform glued membrane (thinner thickness) is formed.By adjusting anilox roll
Line number, mesh depth, can have the function that adjust film thickness.
On anilox roll opposite, there is the resilient roller that a surface has seamless bump structure.The rollers can pass through sense
Photopolymer resin corrodes to form salient point, or rubber laser direct engraving forms salient point.The highly controllable of salient point, point-like size are controllable.
Contacted by anilox roll with resilient roller, uniform adhesive film in anilox roll is transferred on the salient point of resilient roller.
On resilient roller opposite, there are a vulcanie bottom roller or metal bottom roller.By pre- coated nano ceramic material every
Film can uniformly be transferred to membrane surface by the extruding of resilient roller and bottom roller, the adhesive film of the bump surface of resilient roller, be formed
Localised application structure smooth, of the same size.
And when the transfer roller is smooth roll 120, the resilient roller is the gravure printing roller 220 that surface has groove 221.Drive
Dynamic smooth roll 120 rolls, so that the surface of smooth roll 120 forms adhesive film.Make gravure printing roller 220 roll with smooth roll 120 to coordinate, so that
Adhesive film is transferred in the groove 221 on the surface of gravure printing roller 220, and the surface of gravure printing roller 220 is located at the part beyond groove 221
(i.e. the blank space of gravure printing roller 220 does not have adhesive film then).The barrier film 500 of pre- coated nano ceramic material is passed through into gravure printing roller
220 with the extruding of hard bottom roller 300, the adhesive film in the groove 221 on the surface of gravure printing roller 220 is transferred to the table of barrier film 500
Face, form localised application structure smooth, of the same size.Such a mode, suitable for the thicker situation of adhesive film thickness.
In other words, using smooth roll material transfer structure, form one layer of uniform glued membrane (thickness is thicker).
On smooth roll opposite, there is the resilient roller that a surface has seamless groove structure.The rollers can be by photosensitive
Resin erosion forms groove, or rubber laser direct engraving forms groove.The depth of groove is controllable, point-like size is controllable.It is logical
Cross smooth roll to contact with resilient roller, uniform adhesive film on smooth roll is transferred on the groove of resilient roller.
On resilient roller opposite, there are a vulcanie bottom roller or metal bottom roller.By pre- coated nano ceramic material every
For film by the extruding of resilient roller and bottom roller, the adhesive film in the groove of resilient roller can uniformly be transferred to membrane surface, be formed flat
Localised application structure whole, of the same size.
The present invention substitutes the modes such as existing coating, spraying by the structure of flexible printing, forms uniform, smooth, coated side
Product at any time can quick-adjustsing non-all standing formula glue-line.Production cost is greatly reduced, improves product quality.
