[0025] As Figures 1-4As shown in the figure, according to an embodiment of the present invention, an on-line processing device for foreign matter adhesion on the shape roller 8 of a twenty-high rolling mill is provided, including: a processing mechanism, after the output end of the processing mechanism contacts the shape roller 8, it can clean the foreign matter on the shape roller 8; a positioning mechanism, the positioning mechanism is connected to the processing mechanism, the positioning mechanism can drive the processing mechanism to move and fix the processing mechanism at a specified position; a control mechanism, the control mechanism is connected to both the positioning mechanism and the processing mechanism, and the control mechanism can control the working states of the processing structure and the positioning mechanism.

[0026] During the production process, when the operator discovers foreign matter adhesion on the roll surface, manually move the positioning device to the position where the foreign matter adheres according to its position. After the positioning device moves in place, directly raise the processing device to make it close to the roll surface. The rolling mill can directly roll at a low speed. As the roll surface rotates, the processing device will brush the foreign matter on the roll surface clean, directly realizing on-line processing. There is no need to stop the machine and eliminate the tension.

[0027] This device further includes a fixing mechanism. The processing mechanism is arranged on the fixing mechanism, and the fixing mechanism is arranged on the frame of the rolling mill.

[0028] The above-mentioned fixing mechanism is usually connected to the frame of the rolling mill by welding.

[0029] The above-mentioned fixing mechanism includes a bottom plate 1 and two side plates 2. Both side plates 2 are connected to the bottom plate 1. The side plates 2 are vertically arranged relative to the bottom plate 1. The two side plates 2 are parallel to each other. Threaded holes are provided on both the side plates 2 and the bottom plate 1. Each threaded hole is connected with a bolt. One end of the bolt contacts the positioning mechanism to fix the positioning mechanism. When installing the positioning mechanism, the relative position between the positioning mechanism and the fixing mechanism can be finely adjusted, and then the position of the positioning mechanism is fixed by the bolt.

[0030] The positioning mechanism includes a first cylinder 3, and the output end of the first cylinder 3 is connected to the processing mechanism.

[0031] The first cylinder 3 is a magnetic coupling rodless cylinder, and the model is CY3R3-1300.

[0032] The above-mentioned positioning mechanism further includes a slider 4. The slider 4 is connected to the output end of the first cylinder 3, and a second cylinder 5 is connected to the slider 4.

[0033] A positioning soft ruler can also be arranged on the above-mentioned slider 4. One end of the soft ruler is fixed on the first cylinder 3, and the other end is arranged on the slider 4. When the slider 4 moves, the telescopic distance of the first cylinder 3 can be judged by reading the soft ruler.

[0034] The processing device includes a second cylinder 5 and a brush head. The output end of the second cylinder 5 is connected to the brush head, and the second cylinder 5 can drive the brush head to move so as to change the pressure between the brush head and the shape roller 8.

[0035] The model of the second cylinder 5 described above can be MBG32-100KZ.

[0036] The above-mentioned brush head includes a base 6 and a cleaning part 7. The cleaning part 7 is arranged on the base 6, and the brush head cleans the plate-shaped roller 8 through the cleaning part 7.

[0037] The cross-section of the above-mentioned cleaning part 7 is a sector ring, and the diameter of the bottom circle of the sector ring is equal to the outer surface diameter of the plate-shaped roller 8, so that the brush head fits with the plate-shaped roller 8.

[0038] The cleaning part 7 includes felt, which is usually 80% wool felt and is fixed to the base 6 after being cut.

[0039] The control device includes an air source triplet, a first manual control valve, a second manual control valve, a first speed regulating valve and a second speed regulating valve; the input end of the air source triplet is connected to the air source, the output ends of the air source triplet are respectively connected to the first manual control valve and the second manual control valve, the first manual control valve is connected to the input end of the first cylinder 3 through the first speed regulating valve, and the second manual control valve is connected to the input end of the second cylinder 5 through the second speed regulating valve.

[0040] Usually, the number of the first speed regulating valve and the second speed regulating valve is two each. The two first speed regulating valves are respectively connected to the air inlet end and the air outlet end of the first cylinder 3, so as to more accurately adjust the telescopic state of the first cylinder 3. Similarly, the two second speed regulating valves are respectively connected to the air inlet end and the air outlet end of the second cylinder 5, so as to more accurately adjust the telescopic state of the second cylinder 5.

[0041] The energy sources of the first cylinder 3 and the second cylinder 5 all adopt compressed air. Because a large amount of oil mist will be generated during the production of the rolling mill, there are potential safety risks and signal interference with the signal of the plate-shaped roller 8 if electric control is adopted. Therefore, pneumatic control is adopted.

[0042] Compared with the prior art, the utility model realizes the treatment of foreign matters adhered to the plate-shaped roller 8 during the production process of the rolling mill, avoids shutdown and eliminates secondary defects brought to the steel coil by tension. The sampling brush head is made of felt, and there will be no secondary adhesion after the treatment. The waste wool felt discarded by the slitting machine in the factory can be used, with low cost and improved utilization of waste materials. During the treatment process, the brush head can be adjusted according to the adhesion firmness of foreign matters to implement convenient treatment. At the same time, the speed and thrust of the positioning device can also be adjusted to realize diversified treatment methods.

[0043] The above are only the preferred embodiments of the utility model and are not used to limit the utility model. For those skilled in the art, the utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
