AUTOMATIC BAG SLITTER, AND METHOD OF USE THEREOF

摘要

The automatic bag opening and slitting machine has a spike star wheels assembly comprising either of one or a combination of star wheels or cylindroid drum like object. The star wheels assembly is provided with spikes which convey a bag, impaled on the spikes when in an extended position, and extends beneath rotary cutting disks driven by two independent pneumatic or electric motors, that may make a continuous cut around three sides of the bag, so that after cutting thereof, the bag comprises two halves joined only at the rear or trailing side of the bag. These two bag halves are unfolded as one half of the bag engaged by the spikes is drawn around the upstream end of the star wheels assembly, while the other half slides over the rocker arm/bag separation bar/slide guide bar, thus emptying the powder/granular content of the bag into a hopper and releasing the emptied bag by retraction of the spikes from the bag for collection therebelow into a chute, for disposal into an endless screw which extrudes the bag into a compaction tube. The compacted bags are thereafter pushed into a waste plastic bag for refuse disposal.
