The present invention relates to a pretreatment facility for removing the rolling oil and other fine contaminants on the surface of the steel sheet during the production of cold rolled steel sheet, and more specifically, the strip edge marks on the brush roll due to the constant time friction of the edge portion of the steel sheet Prevents wear and tear of cold rolled steel sheet cleaning brush rolls to prevent equipment from leaking to the worn parts and shorten the life of brush rolls and to prevent secondary contamination by solution to improve facility protection and steel sheet quality Relates to a device.

Conventionally, as shown in Figure 1, to remove contaminants such as rolling oil and fine iron powder on the steel sheet sprayed with a solution containing caustic soda on the surface of the steel sheet 14 and then brush brush 10 to the direct current motor And the brush roll 10 was rubbed with the steel sheet 14 by centrifugal force to drive the variable motor to clean the surface.

However, when the width of the steel sheet 14 is changed or the thickness thereof is changed in this washing process, there is no special technique corresponding to the strip edge 11 on the brush roll 10 by the edge portion of the steel sheet 14. And this is eventually transferred to the surface of the subsequent steel sheet, causing streak defect 16.

In particular, in the case where the width of the steel sheet 14 is changed in various ways, a plurality of string marks are formed on the brush roll 10, which is then transferred to the subsequent steel sheet, causing significant quality defects.

In addition, the degree of wear of the brush roll 10 is also affected by the thickness variation of the steel sheet 14, but the greater the thickness of the steel sheet 14, the more severe the degree of wear.

On the other hand, the upper brush roll 10 for rotating and washing the rolling oil and the fine scale in the reverse direction 12 on the surface of the steel sheet 14, which is worn because the urethane brush is planted on the surface, so that it will wear out for a certain period of time. It must be replaced. In particular, when the steel plate 14 is plated, the brush that protrudes from the sharp edge of the edge part is rapidly spread and wear is reached at a short time, and when it cannot be replaced in a timely manner, the steel plate 14 is worn through the worn part. The fine scale is adsorbed in the advancing direction as well as the solution flows down and is mailed in the state adsorbed on the steel sheet 14 to secondaryly contaminate the subsequent equipment.

The present invention has been made in view of such a conventional problem, and has been created to propose a solution, and the process of removing the fine contaminants adhering to the surface of the steel sheet to produce cold rolled steel sheet of the steel sheet in the upper and lower roll space that does not contact with the brush roll Automatic control according to width and thickness provides uniform wear of the brush to prevent defects such as strip edge marks as well as to prevent secondary wear due to leakage of the solution. There is a purpose.

The present invention and the support block is installed adjacent to both ends of the brush roll for cleaning the steel sheet in order to achieve the above technical problem; A screw shaft disposed over the support block, the screw shaft having threads in opposite directions toward both ends from a center of the length, and rotatably provided by a screw driving motor; A flow block fitted to the screw shaft and engaged with the screw shaft; A drum base fixed to the bent upper end of the flow block; A rotating drum rotatably coupled to the drum base, the outer peripheral surface of which is provided with a fixed plate; Detachable wear prevention of the cold rolled steel sheet cleaning brush roll is detachably coupled to the fixed plate, including an edge plate provided in various sizes corresponding to the distance from the steel sheet edge to the end of the brush roll for each width and thickness of the steel sheet. It is characterized by the provision of the device.

As shown in Figures 2 to 4, the present invention is supported by a bearing block 200, the steel plate 14 is passed between the gap between the upper and lower pair of brush rolls 220 rotatably provided by the roll drive motor 210 It is configured to prevent the outflow of the solution containing the streaks and caustic soda by filling the edge plate 110 with the edge plate 110 using a pair of edge plate inserter 100 caused by the width and thickness change of the) .

To this end, a fixing plate 120 for fixing the edge plate 110 is provided, the fixing plate 120 is fixed to the rotating drum 130, the rotating drum 130 is fixed to the drum base 140.

The fixing plate 120 is provided in a form in which two plates in the form of an upper plate and a lower plate overlap and are fixed in such a manner that the edge plate 110 is inserted into a space therebetween and then fixed by such a fixing bolt.

In particular, the fixing plate 120 may be installed at a plurality of angles along the outer circumferential surface of the rotating drum 130, it is preferable that three is installed at intervals of 120 °.

The rotating drum 130 is disposed on the drum base 140 as a driving body and is disposed to rotate. For this purpose, the circular gear 148 is integrally fixed to the lower surface of the rotating drum 130, and the circular gear 148 is fixed. The driven bevel gear 146b is engaged with the driven bevel gear 146b, and the driven bevel gear 146b is fixed to the shaft 146c.

The shaft 146c penetrates the drum base 140 in the radial direction and is coupled to each other so that both ends thereof are exposed to the outside, and another driven bevel gear 146a is fixed at one end thereof.

The driven bevel gear 146a is engaged with the driving bevel gear 144, which is fixed on the rotation shaft of the rotary motor 142.

The rotary motor 142 is fixedly disposed on the adjacent side of the drum base 140.

In addition, a portion of the outer circumferential surface of the drum base 140 is fixed and supported by the flow block 150, the flow block 150 is fitted into the screw shaft 170 as a 'b' shaped member is engaged.

In addition, a guide bar 172 is provided to prevent the flow block 150 from rotating when the flow block 150 moves, and the guide bar 172 flows in a form similar to the screw shaft 170. Is fitted to the block 150.

On the other hand, the screw shaft 170 is rotatably fixed by the support block 160, the screw thread formed on the screw shaft 170 is formed to have opposite directions toward both ends starting from the center of the length.                     

Therefore, by the rotation of the screw shaft 170, the left and right pair of flow blocks 150 are flowed in such a way that they have the same flow distance to each other or gather toward the central portion of the screw shaft 170 or open toward each end.

As described above, the edge plate inserter 100 having such a configuration is provided with a pair of symmetrical forms on both sides of the bearing block 200 to which the brush roll 220 is fixed.

In addition, a screw driving motor 162 is fixed to an outer surface of any one of the support blocks 160, and a rotation shaft of the screw driving motor 162 is connected to the screw shaft 170.

Finally, the bottom surface of any one of the flow block 150 is provided with a sensor such as a contactless sensor 190, such as a proximity sensor, directly below the contactless sensor (in accordance with the movement of the flow block 150) A detection unit 180 capable of reacting with 190 is provided, and the detection unit 180 corresponds to the width of the steel sheet 14 to be plated (the width produced is already defined in several kinds). It is marked for exposure so that it can react with 190).

In addition, the edge plate 110 is provided to correspond to the width and thickness of the steel sheet (14).

The operating relationship of the present invention made of such a configuration is as follows.

First, the changeable width of the steel sheet 14 at a distance (space) between the edge portions of the steel sheet 14 passing through the brush roll 220 and the end of the brush roll 220 which is not in contact with the brush roll 220. And the edge plate corresponding to the target steel plate 14 of the edge plate 110 prepared to correspond to each thickness is prepared by fitting the fixing plate 120.

This process is possible because the width and thickness of the steel sheet to be worked in advance by receiving a signal from the controller of the steel sheet 14 in the process of changing the type of the steel sheet 14 is possible.

When the signal is received, the screw drive motor 162 is driven to move the flow block 150. At this time, the width and the minute difference between the width of the corresponding steel plate 14 using the contactless sensor 190 and the detector 180 are determined. The flow block 150 is moved to a position where the end of the edge plate 110 can be disposed.

This can be easily achieved by accurately positioning the position of the detector 180 because the width and thickness of the steel sheet are known in advance.

If the position of the edge plate 110 suitable for the width and thickness of the steel sheet to be changed before this process is not the insertion position, a plurality of bevel gears are arranged to drive the rotating motor 142 to transmit its power And the edge plate 110 may be disposed at an insertion position through a combination of circular gears.

When the flow of the flow block 150 using the above-described screw shaft 170 in the state in which the edge plate 110 is disposed, the edge plate 110 enters through the gap between the brush rolls 220 and then It will be placed in the proper position.
