Description
Technical field
The utility model relates to the surface coating equipment of rolling base material, the two-sided disposable apparatus for coating of particularly a kind of rolling base material.Be applicable to that thickness, the uniformity and Forming Quality to coating layer require extra high accurate coating operation.
Background technology
The surface coated operation of the rolling base material that generally uses at present generally is to comprise successively unreeling → carrying → be coated with → carry → dry → carry → rolling, owing to the base material course of conveying must contact with conveying mechanism, so painting process generally can only the single face coating.When the rolling base material needs double spread; The general secondary that divides is coated with by face; Or adopt and to unreel → to carry → simultaneously coating → conveying → oven dry → conveying → another side coating → conveying → oven dry → conveying → rolling, so the double spread operation is all cumbersome, production efficiency is low; Long flow path, equipment is huge.
The basic layer material applicator of No. 00126836.8 disclosed production lithium ion polymer battery of one Chinese patent application; Employing unreels → carries → and vertical transport → two coater units of employing carry out double spread → two-sided oven dry → conveying → rolling; Can reach the purpose of the disposable completion of rolling base material double spread; Wherein coater unit adopts intaglio process to be coated with the coating method of roller, and structure is coated with roller, coatings tank and scraper by seal and constitutes, and the throughput direction of rotation direction and rolling base material that seal is coated with roller is opposite; Two coater units are arranged on the staggered positions of rolling base material both sides; Interfere with each other when avoiding forming the double spread layer, scraper is used for local coating occasion, need not use scraper during whole coating.
Above-mentioned prior art coating all is the less demanding situation of thickness, the uniformity and Forming Quality to coating layer; If thickness, the uniformity and Forming Quality to coating layer require high especially; Rolling base material after the coating can be carried the gap of setting through a pair of metering roll; Coating layer is wipeed off to setting thickness,, made the coating layer thickness more evenly and eliminate the defectives such as bubble, pore, corn of coating layer simultaneously through metering roll edging is pressed.But in this case; After metering roll is wipeed off coating layer and edging is pressed; Coating can be bonded at the roll surface of metering roll, and and can cling on roll surface in the solid back of doing that coating occurs to a certain degree, the gap width that metering roll is set accumulated error appears and width inhomogeneous; Can't guarantee the parameter and the quality requirement of coating layer, so lack the actual meaning of using.
Summary of the invention
When need using metering roll, the two-sided disposable apparatus for coating of rolling base material exist coating to be bonded at that to a certain degree doing solid and clinging on roll surface can appear in coating behind the metering roll roll surface in order to overcome; The gap width that metering roll is set accumulated error occurs and width is inhomogeneous; Can't guarantee the parameter of coating layer and the defective of quality requirement; The utility model provides a kind of improved rolling base material two-sided disposable apparatus for coating, can overcome the defective of prior art.
The utility model solves the technical scheme that its technical problem adopted: the two-sided disposable apparatus for coating of a kind of rolling base material; Comprise frame and rack-mounted successively let off roll, conveying roller, double spread unit, two-sided baker, conveying roller, wind-up roll; Wherein the double spread unit is a vertical transport to the rolling base material between the two-sided baker; It is characterized in that: frame is equipped with a pair of coating metering units in the double spread unit to the rolling base material transport path between the two-sided baker; The rolling base material passes through in the middle of the gap that two metering rolls of two coating metering units are set; The rotation direction of metering roll is identical with the throughput direction of rolling base material through said gap; Each coating metering units is equipped with flux bath and the roll surface scraper of containing paint solvent, and the inboard roll surface of metering roll is immersed in the paint solvent in the flux bath, and the roll surface scraper is located at the exit of flux bath.
The double spread unit of technique scheme can be made up of the dip tank and the horizontal dip roller that is arranged in the dip tank that causes of containing coating, and wherein the dip roller bottom is immersed in the coating in the dip tank, and said rolling base material is set on the dip roller downside roll surface and carries.
The dip roller of technique scheme can be provided with more than two, and said rolling base material is set on the downside roll surface of all dip roller and carries.
The position of the rolling bearing of the dip roller of technique scheme is higher than the liquid level of the coating in the dip tank, so that rolling bearing can not contact with the coating in the dip tank, improves the durability of rolling bearing; Perhaps the rolling bearing of dip roller adopts ceramic bearing, and rolling bearing just can contact with the coating in the dip tank does not influence durability yet.
The double spread unit of technique scheme can also be to adopt roller coat or spraying method, and roller coat or spraying all can be local or whole application.
The two-sided baker of technique scheme can be provided with more than two, can be provided with conveying roller between a two-sided baker and another the two-sided baker.
One place's conveying roller of technique scheme can be a conveying roller, also can be one group of conveying roller more than two.
The porch of the flux bath of technique scheme also can be provided with the roll surface scraper.
The inboard roll surface of the metering roll of technique scheme can be the downside roll surface of metering roll.
The what is called of technique scheme is installed successively, is to carry the sequencing that arrives each component to install successively according to the rolling base material.
The base material of technique scheme comprises film (general thickness is below the 0.2mm), sheet material (general thickness is at 0.2～0.7 mm) and light sheet (the thin material of general thickness more than 0.7mm).
The beneficial effect of the utility model is: because frame is equipped with a pair of coating metering units in the double spread unit to the rolling base material transport path between the two-sided baker; The rolling base material passes through in the middle of the gap that two metering rolls of two coating metering units are set; The rotation direction of metering roll is identical with the throughput direction of rolling base material through said gap; So can accurately wipe setting thickness extremely off to the double spread layer on the rolling base material, and reach coating layer thickness degree and have the higher uniformity and better coating quality; Because each coating metering units is equipped with flux bath and the roll surface scraper of containing paint solvent; The roll surface inboard of metering roll is immersed in the paint solvent in the flux bath, and the roll surface scraper is located at the exit of flux bath, so a moving week of metering roll revolution; Roll surface just embathes once in the paint solvent in flux bath; And in the exit of flux bath to the coating of roll surface and solvent scraping once by the roll surface scraper, make metering roll roll surface contact rolling base material before, roll surface is fully clean; Guaranteed the accuracy of the gap width of two metering roll settings, thereby guaranteed that rolling base material coating layer thickness, the uniformity and Forming Quality require extra high precision coating effect.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
