[0001] MOVING DEVICE OF PLATED STRIP [0002]

The present invention relates to a transfer device for a plated strip, and more particularly to a transfer device for a plated strip capable of preventing the plated strip from being entangled in the movement of the plated strip and keeping the thickness of the plated layer constant on the surface of the plated strip .

In general, a film is formed on the surface of a strip by various purposes such as heat resistance enhancement and corrosion resistance enhancement. There are various methods for forming a film by coating a strip. However, In order to perform the operation, a method of passing a strip through a plating bath in which a coating solution containing a substance to be coated is stored is mainly used.

The plated layer (not shown) pushed out of the adjustment space 552 can be stably flattened on the surface of the plating strip S by being pushed toward the plating unit 20 side by the air injected from the nozzle bar 53.

According to the nozzle unit 50 described above, it is possible to control the thickness of the plating layer (not shown) formed on the surface of the plating strip S to prevent discoloration of the plating strip S. Further, a plating layer (not shown) that is agglomerated at the edge portion of the plating strip S can be dispersed, and the plating layer (not shown) can be made flat on the surface of the plating strip S. Further, it is possible to increase the flow velocity of the air introduced into the edge portion of the plating strip S and to stably discharge the plating layer (not shown), which is agglomerated at the edge portion of the plating strip S, toward the plating unit 20 have. In addition, the edge portion of the plating strip S can be stably wrapped in correspondence with the width of the plating strip S, and the plating strip S can be prevented from interfering with the slider 551. Further, the slide movement of the slider 551 can be stabilized, the slider 551 can be prevented from being separated from the nozzle unit 50, and the slide movement of the slider 551 can be smoothly performed.

According to the above, according to the transfer device of the plated strip, it is possible to prevent the plated strip S from running in the movement of the plated strip S and to keep the thickness of the plated layer (not shown) constant on the surface of the plated strip S have. Further, it is possible to shorten the assembling and maintenance time of the stabilizing unit 40 and the nozzle unit 50, reduce the manufacturing cost, and modularize the transporting device so as to compactly arrange it.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

Accordingly, the true scope of protection of the present invention should be defined by the claims.
