상기 구성을 설명하면서 참조한 도 2를 근거로 하여, 도 6에 도시된 바와 같이, 본 발명에 따른 스트립 세정설비의 데밍롤 자동 갭 조절장치의 작용을 설명하면 다음과 같다.Based on FIG. 2, which is described with reference to the above-described configuration, as shown in FIG. 6, the operation of the automatic trimming roll gap adjusting device of the strip cleaning equipment according to the present invention will be described.

먼저, 도 6의 (A)에 도시된 바와 같이, 세정된 스트립(S)의 상하부면에 존재하는 수분을 제거할 때는 본 발명을 구성하는 구동실린더(11)를 하향작동시키면, 이의 축에 중심이 고정된 연결베이스(40)가 하향으로 작동하게 되고,First, as shown in FIG. 6A, when removing the water present on the upper and lower surfaces of the cleaned strip S, when the driving cylinder 11 constituting the present invention is operated downward, the center of the axis thereof is centered. This fixed connection base 40 is to work downwards,

상기 연결베이스(40)가 하향 작동하면 이의 양측부에 고정된 작동레버(19a,19b)가 하향 회전식으로 작동하게 되며,When the connecting base 40 is operated downward, the operating levers 19a and 19b fixed to both sides thereof are operated to rotate downward.

이렇게 되면, 이에 고정되어 있는 상기 S형 작동프레임(20a,20b)이 축고정블록(13a,13b)에 고정된 중심축(22)을 중심으로 수직상태에서 회전하게 된다.In this case, the S-type operation frames 20a and 20b fixed thereto rotate in a vertical state about the central axis 22 fixed to the shaft fixing blocks 13a and 13b.

상기 S형 작동프레임(20a,20b)이 회전식으로 작동하게 되면, 이의 내면부의 랙기어(21a,21b)에 기어결합된 피니언기어(18a,18b)가 회전하면서, 상기 축고정 블록(13a,13b)의 가이드(15)에 팽창스프링(14)으로 상호 지지되어있던 롤축(16a,16b)의 간격이 좁혀지는 방향으로 이동하게 되며,When the S-type operating frames 20a and 20b are rotatably operated, the pinion gears 18a and 18b geared to the rack gears 21a and 21b of the inner surface thereof rotate, and the shaft fixing blocks 13a and 13b rotate. It is moved in the direction in which the gap between the roll shaft (16a, 16b) that is mutually supported by the expansion spring 14 to the guide 15 of the),

상기 롤축(16a,16b)의 간격이 좁혀지면, 상부 및 하부 데밍롤(17a,17b)이 상호 거의 접촉하는 상태로 되어 통판하는 스트립(S)의 상하부 표면부에 존재하는 수분을 제거하게 되는 것이다.When the gap between the roll shafts 16a and 16b is narrowed, the upper and lower deming rolls 17a and 17b are brought into close contact with each other to remove water present in upper and lower surface portions of the strip S. .

한편, 상기와 같이 스트립(S)의 수분제거작업이 완료되어 신규한 스트립(S)을 세정설비 내부로 투입시키기 위하여, 상기 상부 및 하부 데밍롤(17a,17b) 사이로 인출용 로프를 통과시키는 경우에는, 상기 스트립(S)의 수분제거작업의 경우 반대로, 구동실린더(11)를 상향으로 구동시킨다.On the other hand, when the water removal operation of the strip (S) is completed as described above, in order to introduce the new strip (S) into the cleaning facility, passing the withdrawal rope between the upper and lower deming rolls (17a, 17b). In the case of the water removal operation of the strip (S), on the contrary, the driving cylinder 11 is driven upward.

이렇게 되면, 이의 축에 중심부가 고정된 연결베이스(40)가 상향으로 작동하게 되고, 이와 동시에 이의 양측부에 고정된 작동레버(19a,19b)가 상향을 회전하는 식으로 이동하게 된다.In this case, the connecting base 40 fixed to the center thereof is operated upward, and at the same time, the operating levers 19a and 19b fixed to both sides thereof move in a manner of rotating upward.

상기 작동레버(19a,19b)가 상향 회전하는 식으로 이동하게 되면, 이에 중심부가 고정되어 있던 S형 작동프레임(20a,20b)이 수직으로 회전하게 되며,When the operation lever (19a, 19b) is moved in a way that rotates upward, the S-type operation frame (20a, 20b) that is fixed to the center is rotated vertically,

상기 S형 작동프레임(20a,20b)의 수직이동작용에 의하여 내면부 랙기어(21a,21b)에 기어결합하면서 롤축(16a,16b)에 삽입 고정되어있는 피니언기어(18a,18b)가 회전하면서, 상기 축고정 블록(13a,13b)의 가이드(15)에 팽창스프링(14)으로 상호 지지되어있던 롤축(16a,16b)의 간격이 멀어지는 방향으로 이동하게 된다.The pinion gears 18a and 18b, which are fixed to the roll shafts 16a and 16b while being geared to the inner rack gears 21a and 21b by the vertical movement of the S-type operating frames 20a and 20b, rotate. The gap between the roll shafts 16a and 16b, which are mutually supported by the expansion springs 14 on the guides 15 of the shaft fixing blocks 13a and 13b, is moved away from each other.

이러한 확장작용이 완료되면, 롤축(16a,16b)에 축결합된 한 쌍의 상하부 데밍롤(17a,17b)의 간격이 벌어지게 되며,When the expansion is completed, the gap between the pair of upper and lower deming rolls 17a and 17b axially coupled to the roll shafts 16a and 16b is opened.

이때 벌어진 갭 사이로 신규 스트립 인출용 로프를 삽입 통과시켜 신규 스트립을 결속하여 인출하면 되는 것이다.At this time, by inserting a new strip withdrawal rope through the gap that is opened, it is good to bind and take out the new strip.

상술한 바와 같이, 본 발명은 하나의 구동실린더에 의하여 상하부 데밍롤의 간격을 조절함으로써, 항시 일정한 수평상태를 유지하도록 간격이 조절할 수 있어 스트립 수분을 제거하는 정상작업이나, 신규한 스트립을 인출하는 비정상작업을 신속히 수행함과 동시에, 정상작업시 스트립 표면에 잔존하는 세정액을 남김없이 제거하는 기능을 수행하여 스트립 표면부 탈지력 확보와 후공정인 소둔공정에서 결함을 방지하는 효과가 있다.As described above, the present invention by adjusting the distance between the upper and lower deming roll by one drive cylinder, the interval can be adjusted to maintain a constant horizontal state at all times to remove the normal operation or strip stripping strip At the same time to perform the abnormal operation quickly, and to remove the cleaning solution remaining on the surface of the strip during normal operation without the effect to ensure the strip surface degreasing power and to prevent defects in the annealing process in the post process.
