Contact with at least one of the first lower inclined surface 128a, the slit nozzle 126, and the second lower inclined surface 128b due to abrasion or misalignment between the slit die 220 and the cleaning head 250). A misalignment condition may occur that fails to maintain When such a misalignment occurs, the misaligned blade may have a problem of insufficient cleaning (removing) of the residual coating liquid of the slit die 220 or no cleaning (removing) of the residual coating liquid at all.

In addition, replacement of the first to third blades 270a, 270b and 270c and the fourth to sixth blades 272a, 272b and 272c may be necessary due to wear or failure (for example, when the blade is broken). In this case, the first and third blade fixing members 290a, 290b and 290c and the fourth to sixth blade fixing members 292a, 292b and 292c are required to release and assemble. The release and assembly operation of the blade holding member not only greatly increases the time required for replacing the blade, but also causes a problem that the blade replacement operation is very cumbersome.

Therefore, a new method for solving the problem of the cleaning head according to the prior art described above is required.

Further, the method 400 for mounting the blades used in the cleaning head for the slit die of the present invention includes a pair of blade cover fixing members (e.g., a pair of first blade cover fixing members 390a1, 390a2 shown in FIG. 3B). Mounting the blade cover 375 on the inclined base 384 to enable fine adjustment (430).

As described above, in the blade mounting structure 300 and the mounting method 400 according to an embodiment of the present invention, any one or both of the first and second cover fixing holes 378a and 378b of the blade cover 375 may be formed. By having a slot shape, the blade 370 and the blade cover 375 can be mounted to allow fine adjustment on the inclined base 384. As a result, even if abrasion of the blade edge portion or misalignment between the slit die 220 and the cleaning head 250 occurs, the cleaning head 350 is always kept aligned with the slit die 320. Can be.

In addition, in the blade mounting structure 300 and the mounting method 400 according to an embodiment of the present invention, the blade 372 stepped portion 389 of the blade holder 380 through the receiving portion 379 of the blade cover 375. Is supported. That is, the blade 372 is not fixedly mounted to any of the blade cover 375 and the inclined base 384 of the blade holder 380. If the blade 372 needs to be replaced, the blade 372 may be simply removed through the receiver 379, and then a new blade may be inserted through the receiver 379. Therefore, in the blade mounting structure 300 according to the embodiment of the present invention, since the blade 372 can be replaced in this simple manner, the replacement time of the blade can be significantly reduced and the replacement operation of the blade can be made very easy. .

As various modifications may be made to the constructions and methods described and illustrated herein without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings be exemplary, and not intended to limit the invention. It is not.
