Such a negative pressure suction type liquid absorbing roll device has the following drawbacks although the rolling oil and the like can be completely removed. The upper and lower porous outer ring rolls 4 rotate while being pressed against the steel plate 1 to perform a liquid absorbing action, so that frictional heat is constantly generated during operation. However, when removing rolling oil or the like adhering to the steel plate 1 having a width narrower than the roll width, the rolls in the portions not in contact with the steel plate 1 do not absorb liquid, so that the surface of the porous outer ring roll 4 dries and deteriorates. At last, there is a danger of bursting.

A few minutes after the suction device 17 is activated,
The outside air introducing solenoid valve 19 is opened, and outside air is introduced into the hollow portion 11b from the other end, as shown in FIG. The opening / closing operation of the outside air introducing solenoid valve 19 is performed at regular time intervals by a timer, for example. By introducing the outside air from the other end at regular intervals, a flow of air in the axial direction of the roll is generated in the hollow portion 11b, and when the liquid absorbing roll 11 rotates at high speed, centrifugal force causes rolling oil or coolant to adhere to the inner wall of the hollow portion 11b. The oil is pushed out to one end of the liquid suction roll 11 so that it can be easily discharged to the outside of the roll.

As described above, after the suction operation of the rolling oil or the coolant oil adhering to the surface of the steel plate 1 is completed, the solenoid valve 17a interposed in the middle of the pipe 16 is closed and Instead of this, the solenoid valve 18c is opened and water is injected into the hollow portion 11b. At this time, in order to prevent a large amount of water from flowing out from the surface of the liquid absorbing roll 11 by pouring water,
It goes without saying that it is configured so that the amount of water can be controlled. In addition, the water once poured into the hollow portion 11b is discharged by a head before performing the suction operation.

As a result, the surface of the lining material 12 in the portion not in contact with the steel plate 1 is uniformly moistened, and the roll surface can be prevented from drying. Then, for example, after 5 minutes have elapsed since the solenoid valve 18c was opened, the solenoid valve 18c was opened.
c is closed and the solenoid valve 18d is opened, and the water in the hollow portion 11b is discharged.

As described above, according to the rolling oil absorbing roll device of the present invention, even when the rolling oil absorbing roll device is applied to a steel sheet having a width narrower than the roll width, as in the conventional liquid absorbing roll device, suction is performed. After the operation is completed, water can be poured into the hollow portion of the liquid absorbing roll to make the lining material on the surface of the liquid absorbing roll evenly moist, so that there is no risk of the lining material drying and bursting. In addition, during the suction operation, by periodically sending pulsed air into the hollow part of the liquid absorption roll, it is possible to prevent the fluid from adhering to the inside due to centrifugal force, and the suction effect does not deteriorate, so that the liquid absorption is normal. You can take action.
