Self-stacking spiral modular plastic conveyor belt

摘要

A modular spiral belt constructed of a series of hingedly interconnected belt modules arranged in a helical stack. The modular spiral belt includes outer side plates that include openings for airflow and inner side plates that are solid to block airflow. The openings may include valves for selectively opening and closing the openings. A locking mechanism may lock two tiers together. A hold down may apply pressure to prevent destacking of the belt, or a guide may be disposed with the helical stack for preventing destacking.

主权项

1. A conveyor belt module comprising:
a central portion extending longitudinally from a first end to a second end, laterally from a first side edge to a second side edge and in thickness from a top surface to a bottom surface; a first solid side plate coupled to the first side edge for blocking airflow, the first solid side plate comprising two overlapping solid planar portions connected by a central spine, the first solid side plate including a lead edge comprising a first straight lower portion and a first angled upper portion and a lag edge comprising a second straight lower portion and a second angled upper portion that is parallel to the first angled upper portion; and a second side plate coupled to the second side edge, the second side plate including at least one opening to allow airflow therethrough.
