second press wheels

1421 and 1422, and the first and

second press wheels

1421 and 1422 are located at both ends of the second shaft and cooperate with the third drum 1410. 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.

The pressing areas with different sizes are formed on the packaging bag by the first roller assembly and the second roller assembly, so that the thrust to the packaging bag in the bag removing process is increased, and the packaging bag can be conveniently broken by the sampling rod.

The sampling wand is positioned within the first passage 1330 and the second passage 1430.

In this way, damage to the sampling wand is avoided.

Optionally, a damping layer 1411 covers an outer circumferential surface of the third drum 1410, and the pressing wheel presses against the damping layer 1411. The damping layer 1411 can increase the friction force, and the material of the damping layer 1411 is the same as that of the damping ring 1311, and is not described herein again.
