Description
Technical field
The two-sided extrusion apparatus for coating for being suitable for microporous substrate is the utility model is related to, especially one kind is suitable for lithium battery
In the two-sided extrusion apparatus for coating of microporous substrate in manufacturing process.
Background technology
In the production of lithium battery, the production of positive pole substrate and negative pole substrate is using coating process.Existing coating
Method has two kinds, is to be coated with roll-type batch (-type) coating method and squash type coating method respectively, in both coating methods, wherein
Again with squash type coating method because coating accuracy is high, and it is easily controlled, and is widely welcome.
When squash type coating method on the two sides of base material to be coated, generally there is two ways, one kind is first to base
The one side of material is coated, and after drying, then the another side of base material is coated and dried；The realization of this mode typically all needs
Two groups of coating apparatus are wanted, successively the two sides of base material is coated and dried, but are the drawbacks of such a mode, use is set
Standby to take up an area greatly, initial stage, input was big, and utilization rate of equipment and installations is not high；Another mode is that two coatings are set before drying box
Head, wherein the first extrusion coated head coordinates realization to be coated in the upper surface of base material with applicator roll, and the second extrusion coated head
The downside of base material between applicator roll and the import of baking oven, is coated to the lower surface of base material, so as to realize to base material
Double spread, after double spread, enter back into drying box and dry.
Two kinds of above-mentioned double spread modes are applied to the base material that existing surface is in plane, still, for hole
Base material（Hereinafter referred to microporous substrate）During upper progress double spread, above-mentioned two ways is then less applicable, concrete reason
For：If using the first above-mentioned coating method, because the first coating method is that facet is successively coated with, in this way
Following defects be present, one, the adhesive of the coating on two sides is inconsistent, the coating shedding of the one side applied after easily causing, because first
The one side of painting after coating, is understood some coating and is distributed to through the micropore on base material on the substrate surface of another side, dried
After leave on a surface, and when being coated again on the surface, the coating that applies afterwards then combined with the coating of residual it is bad, just
Can influence this face coating and base material directly in conjunction with therefore the problem of the coating applied after causing easily comes off；Two, such a painting
Mode for cloth, coordinate what is be coated using coating head and applicator roll, so after first time is coated with, can be residual on applicator roll
Coating is stayed, is increased over time, the coating remained on applicator roll is more, last just to need timing to shut down to being coated with roller surface
Cleaned, influence the continuous operations of coating apparatus, coating efficiency is lower；If using second above-mentioned of coating method,
That is double spread before it is dried, is dried when entering back into drying box.Although the adhesive on coating two sides is better than above-mentioned first method
, still, the problem of adhesive is not quite identical still be present in some；Simultaneously there is also can on applicator roll residual fraction coating,
The problem of needing fixed time cleaning applicator roll.
Utility model content
In order to overcome above mentioned problem, the utility model to society provide a kind of Painting effect preferably, coating quality it is higher
, while the higher two-sided extrusion apparatus for coating based on microporous substrate of coating efficiency.
