New conveyor belt cleaner
fromMartin Engineering
US-based Martin Engineering has produced a patented conveyor belt
cleaner which – it says – will reduce the cost of ownership by cleaning
better and lasting longer. A lower purchase price was also one of the
primary goals in designing the Martin® QB1 Cleaner HD, achieved by
adopting state-of-the-art roll forming equipment as part of Martin
Engineering’s manufacturing capabilities.
“Rather than fabricating the main frame from individual steel pro-
files welded together, the frame for the new design is roll formed out
of a single piece of steel, which produces an extremely strong and
durable component,”explains Paul Harrison, Director of the Conveyor
Products Business Group. “The process eliminates the time-consum-
ing steps of having to weld any portion of the frame, which also
contributes to the reduced purchase price.”
Described as one of the most comprehensive patents the com-
pany has ever been awarded, protection covers the main frame
design, manufacturing process and attachment method. The new
cleaner features Martin Engineering’s unique ‘CARP’ (Constant Angle
Radial Pressure) technology to maintain the most efficient cleaning
angle throughout service life, with a no-tool replacement process
that can be performed safely by one person in less than five minutes.
“We’ve simplified the manufacturing process and also re-engi-
neered the blade itself,” Harrison continues. “The new profile is less
complex to produce, and because it can be roll formed or manu-
factured on a press brake, it will be easier to source throughout the
world from any Martin Engineering manufacturing site.”
The new design also features a special alignment system to
facilitate extremely precise installation. “One of the most common
problems we see in the field is primary cleaners installed in the wrong
position,” says Senior Product Specialist Dave Mueller. “This cleaner
was engineered for easy, accurate installation.”
The QB1™ Cleaner HD can be retrofitted onto any existing Martin
Engineering tensioners, as well as most competitive systems.
In addition to its cost advantages, the design features a square
mainframe positioned to shed dust and spillage. The urethane blade
formulation can accommodate belt speeds of up to 4,6 m/s and ser-
vice temperatures of -40° to 70°C.
The product is available in lengths of 457 to 2 438 mm and can also
be ordered in 3,05 m sections, allowing distributors or customers to
cut to length for increased versatility.
