[0002] The width of aluminum strip produced by the cold rolling mill varies, but the rolling process needs to ensure that the center line of the strip is consistent with the center line of the cold rolling mill. The coiling of the strip head (outer ring) is prone to deviation, causing wrinkles on the plate surface, or the coiling of the strip tail (inner ring) deviates, causing the edge of the strip to scrape against the edge of the frame and cause equipment failure. It is inconvenient for operators to quickly identify whether the strip is on the center line of the cold rolling mill and further adjust the center position, affecting production efficiency.

[0015] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.
[0016] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application; as used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form, and it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.
[0017] Auxiliary device to prevent strip deviation in cold rolling mill, reference Figure 1 , including a measuring device 1, a connecting bracket and a sleeve 5; the measuring device 1 is used to measure the position of the strip; the measuring device 1 is connected to the sleeve 5 through the connecting bracket, and the sleeve 5 is used to be fixed on the cold rolling mill 8.
[0018] Specifically, the measuring device 1 is an infrared positioning lamp.
[0019] Specifically, the connecting bracket includes a first connecting end, a fixed frame and a second connecting end; the first connecting end, the fixed frame and the second connecting end are fixedly connected in sequence.
[0020] Specifically, the first connection end is fixedly connected to the measuring device 1 .
[0021] Specifically, the second connecting end is fixedly connected to the sleeve 5 .
[0022] Specifically, the connecting bracket includes a first fixed edge 2, a second fixed edge 3 and a third fixed edge 4; one end of the first fixed edge 2 is fixedly connected to one end of the second fixed edge 3, the other end of the first fixed edge 2 is fixedly connected to the middle of the third fixed edge 4, and the other end of the second fixed edge 3 is fixedly connected to one end of the third fixed edge 4; the other end of the third fixed edge 4 forms the first connecting end; the connection between the first fixed edge 2 and the second fixed plate 3 forms the second connecting end.
[0023] Specifically, the pipe sleeve 5 is a cylindrical fixed sleeve with a notch in its cross section; the pipe sleeve 5 is sleeved on the slide rail 6 on the cold rolling mill and is coaxially arranged with the slide rail 6 .
[0024] Specifically, the slide rail 6 is fixed to the cold rolling mill 8 by bolts 7 .
[0025] Adjust the infrared positioning line to the width indicated on the corresponding scale of the steel plate according to the strip width. When the outer ring strip is threaded, the operator uses the scale position of the infrared positioning line as a reference to operate the cold rolling mill uncoiler centering mechanism to adjust the strip center position to ensure that the strip is consistent with the center line of the cold rolling mill.
[0026] When producing thick materials such as billets, the tail (inner ring) must be rolled over directly without leaving any waste. When the tail of the strip is released from the unwinding shaft, the unwinding tension will automatically disappear. The tail strip is in a state of no traction and tension. Changes in plate shape and tilting rollers cause inconsistent rolling thickness on both sides of the strip, which makes it easy for the strip to deviate to one side. In severe cases, it will scrape the edge of the frame. This time, the operator refers to the infrared indication position to observe whether the edge of the tail of the strip remains aligned with the infrared "I" line. If a slight deviation is found, the main operator must be informed in time to adjust the direction of the tilting roller for correction. If the deviation is serious, the machine can be stopped decisively to avoid further deviation.
