ABSTRACT:
A bag opening machine includes a trough and a feed screw that is rotatably mounted in the trough to advance bags that at least partially fit between the flight of the feed screw along the length of the trough. There are a pair of restrictions that the bags encounter that cause the bags to be ripped open. The machine has a shear plate running the length of the trough which provides a surface against which bags between the flight rub to be opened. The flight of the conveyor is provided with pins which project generally in a down stream direction and assist in ripping open bags. Each of the restrictions is lined with another shear plate. An expansion chamber is located between the two restrictions. The restrictions completely surround the feed screw, which is mounted eccentrically in the opening defined by the feed screw. A hinged lid over the expansion chamber helps prevent the build-up of excess material. At the outlet end, the feed screw has a conical anti-clogging device that directs materials out of the feed screw, especially long strips that might have gotten wrapped around the feed screw.
