Abstract
The utility model discloses novel two-roller-press-fit reverse coating equipment. The equipment mainly comprises an unwinding device, a coating device, a drying device, a winding device and a control system, wherein the coating device consists of a first aluminum roller, a second aluminum roller, a coating roller, a material tank and a press roller, the coating roller is located in the material tank, the first aluminum roller and the second aluminum roller are in double-roll connection, the second aluminum roller is driven by the first aluminum roller, the coating roller and the second aluminum roller are in double-roll connection and are driven along the same direction, and the press roller presses the second aluminum roller. The equipment has the beneficial effects that a coating head of the coating device adopts a reverse coating manner instead of the traditional reticulate pattern coating manner, so that a coated surface is uniform and has no reticulate pattern marks, and the coating quantity can be adjusted; and the full-scale coating for the surface of a substrate can be realized, so that the substrate waste is effectively reduced, and the economic benefit is increased.
Description
Technical field
The utility model is that reverse coating apparatus is closed in a kind of two novel roll-ins, is applied to coating and the composite packaging of base materials such as paper and film, belongs to the printing packaging field.
Background technology
The coating equipment complex is mainly used in gluing coating and the Compound Machining of multiple reel base materials such as plastic sheeting, stationery, electrochemical aluminium, cloth and leather.It is widely used in all kinds of packaging fields, and vast potential for future development is arranged.The coating equipment complex roughly divides smooth roll gluing coating, anilox roll gluing coating.
Two roller transfer coated are adopted in smooth roll gluing coating usually.Adjust the gap between its upper glue roller and the applicator roll, just can adjust the size of coating weight.The structure of whole dispense tip part is comparatively complicated, requires machining accuracy and the assembly precision height of upper glue roller, applicator roll, carry-over pinch rolls and scraper, and cost is also than higher.The reticulate pattern coating apparatus mainly adopts reticulate pattern (celophthalmia) applicator roll to carry out the gluing coating.Its coating is even, and coating weight relatively accurately (is regulated but coating weight is very difficult).When being coated with anilox roll, coating weight is mainly relevant with the precision of the celophthalmia degree of depth of anilox roll and glue kind.The celophthalmia degree of depth of anilox roll is more dark, and glue is transferred to the amount that base material gets on from celophthalmia corresponding also more many; Otherwise the anilox roll net celophthalmia degree of depth is more shallow, transfers to also corresponding the reducing of amount on the base material.With viscosity much relations are arranged also.The too big and too little normal transfer that all is unfavorable for glue of glue viscosity.The glue viscosity is difficult for greatly shifting, and too rare then easily trickling makes gluing inhomogeneous, easily produces vertical or horizontal flowing water line.So in case after the kind of coating anilox roll and glue is decided, just be difficult to regulate its coating weight, this also is the main cause that the application of reticulate pattern applicator roll is restricted.
The utility model content
In order to solve the inhomogeneous problem of coating weight control of reticulate pattern coating method, the utility model provides a kind of two novel roll-ins to close reverse coating apparatus.
The purpose of this utility model is come specific implementation by the following technical programs:
Reverse coating apparatus is closed in a kind of two novel roll-ins, mainly formed by unwinding device, apparatus for coating, drying unit, wrap-up and control system, described apparatus for coating is made up of the first aluminium roller, the second aluminium roller, applicator roll, hopper and pressure roller, described applicator roll is positioned among the hopper, the first aluminium roller and second aluminium is roll-to-roll to be connected and to drive the second aluminium roller by the first aluminium roller, described applicator roll closed and drives in the same way with roll-to-roll connection of second aluminium, and described pressure roller is pressed on the described second aluminium roller.
At apparatus for coating a protective cover is installed, on protective cover, is respectively had one to be parallel to the slit that applicator roll is used for the film folding and unfolding with the side.Be square structure and by the transparent material manufacturing of described protective cover.Protective cover is polymer composite, has transparent, shock resistance, corrosion resistant characteristic.
Between described apparatus for coating and drying unit, be provided with first carry-over pinch rolls, be provided with second carry-over pinch rolls between described drying unit and the wrap-up.
The beneficial effects of the utility model are, dispense tip at apparatus for coating adopts reverse coating method, replace traditional reticulate pattern coating method, even, the no reticulate pattern of coating surface prints, can regulate coating weight, and can realize full width of cloth coating at substrate surface, effectively reduce the waste of base material, increase economic benefit.
Description of drawings
Be described in further detail with the utility model of embodiment with reference to the accompanying drawings below.
Fig. 1 is the structure chart that reverse coating apparatus is closed in the described two novel roll-ins of the utility model embodiment.
The specific embodiment
As shown in Figure 1, reverse coating apparatus is closed in the described two novel roll-ins of the utility model embodiment, mainly by unwinding device 10, apparatus for coating, drying unit 7, wrap-up 9 and control system are formed, described apparatus for coating is by the first aluminium roller 4, the second aluminium roller 5, applicator roll 3, hopper 1 and pressure roller 11 are formed, described applicator roll 3 is positioned among the hopper 1, in the hopper 1 coating fluid is housed, the first aluminium roller 4 is connected with the second aluminium roller, 5 pair rollers and drives the second aluminium roller 5 by the first aluminium roller 4, described applicator roll 3 is connected with the second aluminium roller, 5 pair rollers and closes and drive in the same way, and described pressure roller 11 is pressed on the described second aluminium roller 5.
At apparatus for coating a protective cover is installed, on protective cover, is respectively had one to be parallel to the slit that applicator roll is used for the film folding and unfolding with the side.Be square structure and by the transparent material manufacturing of described protective cover.Protective cover is polymer composite, has transparent, shock resistance, corrosion resistant characteristic.
Between described apparatus for coating and drying unit 7, be provided with first carry-over pinch rolls 6, be provided with second carry-over pinch rolls 8 between described drying unit 7 and the wrap-up 9.
The beneficial effects of the utility model are, dispense tip at apparatus for coating adopts reverse coating method, replace traditional reticulate pattern coating method, even, the no reticulate pattern of coating surface prints, can regulate coating weight, and can realize full width of cloth coating at substrate surface, effectively reduce the waste of base material, increase economic benefit.
