ABSTRACT:
A low back pressure belt module for forming an endless belt for use with a conveyor. The modular conveyor belt is formed of rows of belt modules pivotally interlinked by transverse pivot rods. The belt modules have a plurality of first link ends disposed in the direction of belt travel and a plurality of second link ends disposed in the opposite direction. Transverse holes in the link ends are aligned to accommodate a pivot rod. When the link ends of the consecutive rows of side-by-side modules are intercalated, the pivot rod serves as a hinge pin in a hinged joint between consecutive interlinked rows. The low back pressure belt modules include shafts supported above the top surface of the module. The shafts carry a plurality of rollers to form a low back pressure conveying surface. A pair of intermediate supports may be provided for each shaft. The intermediate supports are L-shaped and disposed in mirror relation such that one support engages one side of the shaft and the other support engages the other side of the shaft in complementary fashion. The intermediate supports are offset in the transverse direction such that the shaft is disposed in an open configuration with access to the shaft for cleaning and without a narrow slot for debris to accumulate.
