The distance between the third drum 1410 and the pressing surfaces of both sides of the fourth drum 1420 is greater than the distance between the pressing surfaces of both sides of the first drum 1310 and the second drum 1320. That is, in the actual operation process, after the packaging bag passes through the first roller assembly, the first pressed area is formed on the side edge in the long side direction, and after the packaging bag passes through the second roller assembly, the second pressed area is formed on the side edge in the long side direction. The width of the first compressed area is greater than the width of the second compressed area on one long side of the packaging bag. That is, the edge of the first gripped area that is distal to the long edge of the bag is closer to the sampling wand than the edge of the second gripped area that is distal to the long edge of the bag.
