Abstract: A motorized or drive roller (1) of a belt conveyor (100) provides, mounted forcedly thereon, an antiwear tube (3) made of PVC additioned with antiwear additives, so that the belt (2) of the belt conveyor (100) rotates around, and in contact with, the antiwear tube (3).
Abstract: A tensioning device for a conveyor belt (10) used for moving semi-finished or finished products along the lines of production or storage or the like, includes mechanical elements integrated in the structure of a frame (12) of the conveyor belt, provided with a roto-translation movement with manual actuation and co-operating with thrust elements with translation movement for adjusting the tension of a moving mat (16) via a change in the center distance between a reversing roller (20) and a motor roller (18) which subtend the moving mat and are transversely arranged at opposite ends of two opposing and parallel lateral shoulders (14) of the frame (12) of the conveyor belt.
Abstract: An elevator conveyor belt (10) with adjustable slope, suitable for moving semi-finished or finished products on different levels along production lines, includes a supporting and stiffening frame (12) divided in at least two adjacent sections defined by a horizontal section (14) or load section arranged according to a horizontal plane and by an elevator section (16) arranged according to a sloped plane and a belt (28) tensioned between an opposed head end of the horizontal section (14) and a tail end of the elevator section (16) and slidably actuated by an electrical motor (25), the horizontal or load section (14) and the elevator section (16) being reciprocally hinged by a hinged connection (13) including mobile elements suitable for ensuring a constant tensioning of the belt (28) with the change of the reciprocal slope between the sections.
