Abstract
A tensioning and tracking system with specific useful features for adjusting a conveyor belt is disclosed. Generally, the tensioning and tracking systems include a pair of plate members attached together and defining a channel and an elongated opening. Mounted within the channel is a slide plate having a distal end. Also, connected to one of the side plate members is a rotating member for reciprocally advancing the distal end of the slide plate into the elongated opening. The position of the slide plate within the elongated opening is secured by a locking screw connected to one of the plate members.
Claims21
A device mounted to a conveyor for selectively positioning a pulley comprising:
- an assembly defining a passage and an elongated opening, the passage having a pair of parallel side walls and a pair of parallel longitudinal walls extending perpendicularly in relation to the side walls;
- a slide plate slidably mounted within the passage and having a distal end;
- and
- a thumb wheel operably connected to the assembly for reciprocally advancing the distal end of the slide plate into the elongated opening by a select distance.
A device mounted to a conveyor for selectively positioning a pulley along a longitudinal axis defined by a pair of side rails comprising:
- a pair of assemblies with each assembly attached to one of the side rails and including a pair of plate members attached together and defining a cavity and an elongated opening, one of the plate members abutting against one of the side rails and the other plate member attached to the side rail, the cavity having a pair of parallel side walls and a pair of parallel longitudinal walls extending perpendicularly in relation to the side walls;
- a slide plate mounted within the cavity and having a concave distal end abutting one end of the pulley;
- and
- a thumb wheel operably connected to at least one of the plate members for longitudinally advancing the slide plate and one end of the pulley by a select distance.
A device mounted to a conveyor for selectively positioning a pulley along a longitudinal axis defined by a pair of side rails comprising:
- a pair of assemblies with each assembly attached to one of the side rails and including a pair of plate members attached together and defining a cavity and an elongated opening, one of the plate members abutting against one of the side rails and the other plate member attached to the side rail, at least one of the plate members defining an aperture, the cavity having a pair of parallel side walls and a pair of parallel longitudinal walls extending perpendicularly in relation to the side walls;
- a slide plate mounted within the cavity and having a concave distal end abutting one end of the pulley;
- and
- a thumb wheel having a portion received in the aperture defined by at least one of the plate members for longitudinally advancing the slide plate and one end of the pulley by a select distance.
