Description

Feed roll cleaning device {The machine for cleaning feed roll}

The present invention relates to a feed roll cleaning device, and in particular, to remove the foreign matter on the surface of the feed roll, which advances the strip from the shear line of the plate to the shear knife, to enhance the safety of the operator and to improve the quality of the worker. The present invention relates to a debris removal device on the surface of a feed roll that may contribute.

In general, when a strip (steel sheet) is manufactured by rolling, an elongated sheet is formed. The long strip is then cut to the desired length. For this purpose, the long strip is transferred to the position of the shear knife by using a feed roll. At this time, the feed roll will repeat the rotation and stop.

1 is a structural diagram of a general feed roll facility, in which a strip 4 is fed between an upper roll 1a and a lower roll 1b to rotate the upper roll 1a and the lower roll 1b. The process moves to this position. Because of the long length of the strip 4, the strip may deflect in the middle. In order to prevent this, the interroll 2 was installed in the middle of the strip to prevent sagging. The interroll 2 prevents sag as well as facilitates smooth movement of the strip. The interroll can be freely rotated by mounting a number of small rolls on the holder 2a. The pinhole detector 3 is installed in the middle of the strip is transferred to detect the length of the strip (4) is fed.
