[0002] After rolling, the aluminum foil blank needs to be cut on a shearing machine. The disc knife in the shearing machine cuts the aluminum foil blank into aluminum foil products of specified size. Then the aluminum foil products are rolled up by the winding roller after passing through the pressing roller. The shearing machine will produce aluminum scraps when cutting the aluminum foil blank, and the waste needs to be cleaned up to avoid affecting the quality of later production. The existing announcement number is CN217123348 U, which is a purging device for shearing aluminum foil blanks. The purging position of the nozzle is adjusted by the driving mechanism to meet the use requirements of aluminum foil blanks of different widths. The purging angle of the nozzle is adjusted by the electric control telescopic rod to ensure that there is no blind spot in the purging area of ​​the nozzle. However, when the above device is in use, a cross area will appear between the nozzles on both sides, and effective purging cannot be performed, which affects the purging quality.
