A method for forming a one-piece integral multi-durometer scraper blade for a conveyor belt cleaner. The scraper blade includes a body extending longitudinally between a first end and a second end and extending transversely between a base and a tip. The body includes a first body portion comprising a first elastomeric material having a first durometer of hardness, and a second body portion comprising a second elastomeric material having a second durometer of hardness.

The body also includes a transition portion located between the first body portion and the second body portion.

Multiple durometer conveyor belt cleaner scraper blade

A conveyor belt cleaner and tensioner assembly including a conveyor belt cleaner and a conveyor belt cleaner tensioner. The conveyor belt cleaner includes a scraper blade assembly having a mounting member and a scraper blade. The mounting member includes a base member adapted to be attached to a cross shaft and first and second flanges extending outwardly from the base member forming a first slot therebetween. The scraper blade includes a mounting base having a bore through which the mounting member extends, second and third slots adapted to receive the first and second flanges of the mounting member, and a third flange adapted to be inserted in the first slot of the mounting member such that the scraper blade is rotatably attached to the mounting member. The tensioner includes a support arm rotatably attached to a rotatable tensioning rod and a pivot arm pivotally attached to the support arm which receives the cross shaft. A biasing member extends between the support arm and the pivot arm. Rotation of the tensioning rod moves the support bracket and pivot arm along the tensioning rod until the scraper blades engage the conveyor belt, whereafter continued rotation of the tensioning rod compresses the biasing member to resiliently bias the scraper blades into engagement with the conveyor belt.
