The uniform apparatus for coating of card coating.
Background technology
Coating be lithium ion battery either lithium-ion capacitor positive/negative plate and barrier film production process in must can not
A few procedure, the quality of coating process will directly affect the performances such as the capacity and uniformity of battery or electric capacity.Coating
Process be exactly that the pasty state viscous paste that will make is uniform, continuously or discontinuously be coated in base material (copper foil or aluminium foil) just
Reverse side.Existing coating method is the top or side that coating head is arranged on to base material, i.e. slurry from being coated on above base material, or
Coating head is arranged on the side and lower section of foil by person simultaneously, and upper and lower surface is coated with simultaneously.This is for common nonporous substrate
Speech is not in defective workmanship, but for porous substrate, due to the Action of Gravity Field of slurry, slurry easily oozes from the hole of base material
Leakage, this not only influences the coating process of base material, causes base material to be unevenly coated, and seepage slurry due to not in time drying and
Stain applicator roll, it is impossible to normal production.In addition, in traditional coating process, coating head is arranged at the head position of baking oven, such as specially
Described in the sharp B of document CN 103567116 and CN 102744183 A, there is certain defect in this coating method.Due to baking oven
Fluctuation occurs in interior larger air velocity, base material during traveling, in turn results in base material and is unevenly coated, so as to influence production
Product uniformity.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of apparatus for coating for being suitable for porous substrate, uses
The device be coated on porous substrate avoid porous substrate be unevenly coated and material leakage pollute applicator roll defect.
In order to solve the above technical problems, the utility model discloses a kind of apparatus for coating for being suitable for porous substrate, including
Base material, the unreeling machine roller being sequentially arranged along base material direct of travel, applicator roll, baking oven, carry-over pinch rolls and winder roller, and to base material
The coating head being coated, the coating head is arranged at below applicator roll.
Further, the point of contact of the base material and applicator roll is A, and the top of the coating head is spray head B, spray head B
It is 0.5-5mm with horizontal range Ls of the point of contact A on base material direct of travel.Coating head is on base material direct of travel closer to coating
Roller point of contact, then during coating operations, base material fluctuation is smaller, and coating homogeneity is better.
Further, coating head down suction H of spray head B to base material in coating operations is 0.2-1mm.Coating
After operating mode is determined, the clearance constant between coating head and applicator roll, to ensure the uniformity for applying cloth base material.
Further, the base material is copper foil, aluminium foil, nickel foil, steel mesh, any one in barrier film.

Further, the unreeling machine roller has two or more, for base material to be rolled out, and increase unreeling machine roller can be with
Ensure that base material, in the flatness of direct of travel, is more uniformly distributed coating.
Further, the apparatus for coating also includes release roller, and the release roller is arranged at the top of base material, and positioned at painting
Between cloth rewinder roll and baking oven.Increasing release roller and can reducing causes the larger ripple of base material because of quick air flow near baking oven
It is dynamic.
Further, the base material passes through along baking oven horizontal direction, and baking oven is done from both direction up and down to base material
It is dry.
Further, the base material is located at 2/3rds before baking oven and passed through in the horizontal direction, at rear 1/3rd
It is inclined upwardly from horizontal direction, until base material is completely by baking oven, and base material is dried from both direction up and down for baking oven.
Further, risen at the baking oven 2/3rds and support roller is set, and support roller is placed in the top of base material, for propping up
Support group material is advanced along lead.
Further, the carry-over pinch rolls at least two, carry-over pinch rolls as base material trailer system, by base material along winding
Machine roller coiling direction is advanced.
The beneficial effects of the utility model：Because coating head is located at the lower section of applicator roll, slurry is by coating head by lower
On be coated, can avoid slurry material leakage and stain the defect of applicator roll, it is ensured that base material coating is uniform；Secondly as coating
Position is in below applicator roll, so base material fluctuates smaller during traveling, so as to ensure the uniformity of coating, and then is improved
Prepare the chemical property of electrode.
