Abstract
The utility model relates to a kind of three roll reverse coaters, comprises coating roller, doctor roll, disappear line roller, peristaltic pump and conveyer belt, coating roller be arranged at bottom, its underpart be coated with sheet material and directly contacted; Doctor roll and the line roller that disappears are close to coating roller respectively and arrange and form groove at doctor roll and coating roller contact position; Peristaltic pump is used for masking liquid to be delivered to doctor roll and contacts with coating roller in the groove that place formed; Used for conveyer belt in conveying by painting sheet material make it to pass through from coating roller.Coating roller is surface finish rubber roll, and doctor roll is surface textures steel rider, and the line roller that disappears is surface finish steel rider.The utility model is used in the plate surface coating ultra-thin film layers such as glass, plank or steel plate, even film layer.
Description
Technical field
The utility model relates to a kind of roll coater, and especially a kind of three roll reverse coaters, are applicable at plate surface as glass surface is coated with ultra-thin film layers.
Background technology
Roll coater, full name roll coater.Namely one group is used to turn round roller a certain amount of coatings to the device in planar material.Change the pressure between two rollers, the thickness of coating can be regulated.Typical roll coater has roll coater, pressure roller coating machine, positive and negative roll coater etc.
Roll coater great majority are in the market three roll reverse coaters, as Fig. 1, it comprises pick-up roller, coating roller and metering roll, its application mode is: pick up masking liquid by pick-up roller, to metering roll and coating roller, control thickness by the spacing between metering roll and coating roller again, then transfer on the coiled material that is coated.Although such technique reaches to a certain extent, technique is simple, application effect easily, and this roll coater is only applicable to the flexible coiled material of application, as coil of strip, aluminium volume or roll of plastic, and can not carry out coating decoration to sheet material.If do not adopt inverse roller coating, namely coating roller direction of rotation is consistent with sheet material direction of advance, and masking liquid is just difficult to transfer to by painting plate surface, therefore must use reverse application to the application of sheet material.
Summary of the invention
The technical problems to be solved in the utility model proposes a kind of three roll reverse coaters, adopts this three roll reverse coater can carry out the application of reverse ultra-thin film layers at plate surface.
The technical scheme that the utility model technical solution problem adopts is: a kind of three roll reverse coaters, comprise coating roller and doctor roll, it is characterized in that, also comprise disappear line roller, peristaltic pump and conveyer belt, described coating roller is arranged at bottom, its underpart be coated with sheet material and directly contacted; Described doctor roll and the line roller that disappears are close to coating roller respectively and arrange and form groove at doctor roll and coating roller contact position; Described peristaltic pump is used for masking liquid to be delivered to doctor roll and contacts with coating roller in the groove that place formed; Described used for conveyer beltly made it to pass through from coating roller in conveying by painting sheet material.
Described coating roller is rubber roll, and described doctor roll and the line roller that disappears are steel rider.
As preferably, described coating roller is surface finish rubber roll.
As preferably, described doctor roll is surface textures steel rider.
As preferably, the described line roller that disappears is surface finish steel rider.
The utility model is used in plate surface coating ultra-thin film layers, and described sheet material can be glass, plank or steel plate etc.Sheet material from process below rubber roll, and extrudes with rubber roll, and masking liquid is just transferred on sheet material and forms thin layer.
During the utility model practical application, masking liquid extraction is formed groove to doctor roll and coating roller contact position by peristaltic pump, rotate coating roller and doctor roll simultaneously, namely masking liquid is transferred on coating roller, when under the conveying of sheet material at conveyer belt below coating roller through out-of-date generation friction and Extrusion, namely masking liquid is transferred on sheet material and forms thin layer.The decorative pattern order number on adjustment doctor roll surface can control the band liquid measure of coating roller; The effect of line roller of disappearing is to roll rubber roll (coating roller), and coated article matter is uniformly distributed at roll surfaces.
The beneficial effects of the utility model are: inverse roller coating is successfully applied to sheet material by (1).(2) when coating roller and doctor roll crush are fixed, the band liquid measure of coating roller can be controlled by the decorative pattern order number on doctor roll surface.(3) in order to control the uniformity of large area sheet material film, using the line roller that disappears to roll rubber roll (coating roller), coated article matter is uniformly distributed at roll surfaces, thus plate surface formation uniform coating can be transferred to uniformly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is existing three roll reverse coater schematic diagrames.In figure: 1-pick-up roller, 2-metering roll, 3-coating roller, 4-coiled material, 5-masking liquid.
Fig. 2 is a kind of detailed description of the invention schematic diagram of the utility model.In figure: 1-coating roller, 2-doctor roll, 3-disappears line roller, and 4-is coated with sheet material, 5-conveyer belt.
Detailed description of the invention
Embodiment 1: a kind of three roll reverse coaters.
As shown in Figure 2, it comprises coating roller 1, doctor roll 2, disappear line roller 3, peristaltic pump and conveyer belt 5, and coating roller 1 is arranged at bottom, coating roller bottom be coated with sheet material 4 and directly contacted; Doctor roll 2 and the line roller 3 that disappears are close to coating roller 1 respectively and arrange and form groove in doctor roll 2 and coating roller 3 contact position.Coating roller 1 is surface finish rubber roll, and doctor roll 2 is surface textures steel rider, and the line roller 3 that disappears is surface finish steel rider.Peristaltic pump is used for masking liquid to be delivered to doctor roll 2 and contacts with coating roller 1 in the groove that place formed.When conveyer belt 5 will be delivered to coating roller 1 time by painting sheet material 4, friction and Extrusion occurs, namely masking liquid is transferred to and is formed thin layer by painting sheet material 4.
The just detailed description of the invention of the present utility model that above description describes, various illustrating is not construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field after having read description can to before described detailed description of the invention make an amendment or be out of shape, and do not deviate from essence of the present utility model and scope.
