Through this, as the sheet-like product 2 is moved, the sheet-like product 2 may be cooled by contacting one side of the rotational moving part 200 supplied with cooling water.

In this case, the rotation moving unit 200 described above may be formed by connecting a plurality of chain blocks 220 arranged along the rotation direction. Specifically, the rotation moving unit 200 is engaged with a plurality of chain gears 231 that are rotationally driven by the driving unit 60 and the above-described chain gear 231 to follow a predetermined path as the chain gear 231 is rotated. It may be formed including a chain rail 230 that is moved along and a plurality of chain blocks 220 located on the chain rail 230.

Each of the plurality of chain blocks 220 described above may be connected to the chain rail 230 and rotate in the same path as the chain rail 230 is moved. That is, the rotation moving part 200 described above is formed in a caterpillar manner so that a plurality of chain blocks 220 may be interconnected through the chain rail 230 and may be rotated together in the same direction.

Meanwhile, the above-described flat surface 210 may be formed by clustering at least some of the plurality of chain blocks 220. In more detail, the plurality of chain blocks 220 positioned above the rotation moving part 200 are interconnected through the chain rail 230 so that the upper surface may be located in a shape similar to one flat surface 210 , The above-described flat surface 210 may be located on the movement path of the sheet-like product 2.

Through this, the sheet-like product 2 is in planar contact with the rotation moving part 200, and the contact area can be made larger than when the shape of the rotation moving part 200 is simply formed in a roll shape.

Meanwhile, the above-described cooling device 10 may further include a cooling water passage part 300 that is in communication with the cooling water supply part 310 and penetrates at least a part of the plurality of chain blocks 220. Specifically, the cooling water flow path part 300 is a cooling water inlet part 300a through which cooling water flows from the cooling water supply part 310, and a cooling water flow path pipe which is located in the above-described chain block 220 to cool the sheet-like product 2 ( 300b) and a cooling water discharge unit 300c from which the cooling water is discharged may be formed.

Therefore, when the coolant flows through the coolant inlet 300a, the coolant can flow along the coolant flow path pipe 300b, and the sheet-like product 2 is moved to make surface contact with the plurality of chain blocks 220. Accordingly, heat of the sheet-like product 2 is absorbed by the cooling water, and the sheet-like product 2 can be quickly cooled.

In addition, the rotary joint 320 may be connected to the cooling water inlet 300a and the cooling water discharge 300c of the cooling water flow path part 300, through which, even when the rotation moving part 200 is rotated, the cooling water flow path The part 300 may be kept tangled or not tangled. Specifically, as the rotation moving part 200 is rotated, the cooling water inlet 300a and the cooling water discharge part 300c of the cooling water passage part 300 connected to the rotation moving part 200 are also together with the rotation moving part 200. It can be rotated, and the cooling water flow path part 300 in the form of a tube or hose is rotated together with the rotating moving part 200 through the rotary joint 320, so that the cooling water is supplied and discharged smoothly without being tangled or twisted. can do.

In addition, as the rotary joint 320 located on the central axis 100 rotates, the cooling water supply pipe 310a and the cooling water collection pipe 310b may also be entangled or twisted, and a rotary joint ( 400) is formed so that the cooling water supply pipe 310a and the cooling water collection pipe 310b can be maintained without being tangled.

Furthermore, the above-described cooling device 10 may further include a pressing unit 500 for pressing the moving sheet-like product 2 toward the rotation moving unit 200. Specifically, the pressing unit 500 may be formed to be spaced a predetermined distance from the flat surface 210 on the upper side of the rotation moving unit 200, and in this case, the pressing unit 500 is damaged by the sheet-like product 2 It is installed to press the sheet-like product 2 toward the rotational moving part 200 within a range that is not, and the above-described predetermined distance may vary depending on the thickness of the sheet-like product 2.
