Powered Drywall Tape Cutter
A power cutter tool for applying drywall tape or plastic drywall trim product that contains a powered blade that can cut the tape or trim material by simply pressing a trigger. The cutter can be powered by a spring or springs, a motor, hydraulically or by any other means. The trigger can be a button, lever, valve or any other means for releasing a powered blade.
1 . A drywall trim cutter used to cut plastic drywall trim comprising, in combination,
a frame containing at least a torsion spring, a rotating mass and rotor, a moving cutting blade, a stationary butting blade, and a cocking handle;
wherein, said torsion spring is coupled to said moving blade, said torsion spring being tensioned by said cocking handle to a cocked position, said torsion spring releasable from said cocked position causing said rotating mass to acquire sufficient momentum to cause said cutting blade to close on said stationary butting blade cutting a section of plastic drywall trim up to ⅛ inch thick between said cutting blade and said stationary butting blade; and
whereby said drywall trim cutter dispenses and cuts plastic drywall trim strips into cut pieces.
2 . The drywall trim cutter of claim 1 further comprising a product guide that guides said drywall trim between said moving blade and said butting blade.
3 . A device for dispensing and cutting plastic drywall trim products comprising:
a frame adapted to be mounted on an elongated handle;
a trim guide attached to said frame;
a driving spring and rotating mass contained by said frame;
a slanted, movable cutting blade that moves between a feed position and a cut position and stationary butting blade that can be engaged by said movable cutting blade, said movable cutting blade and said stationary butting blade contained by said frame;
a cocking handle;
a retaining latch adapted to release said rotating mass from a cocked position;
wherein, said driving spring can be cocked by said cocking handle and retained by said retaining latch, said driving spring mechanically coupled to said rotating mass; and
wherein, when said rotating mass is released, said driving spring causes said rotating mass to acquire sufficient angular momentum to cause said movable cutting blade to cut a piece of plastic drywall trim material at least ⅛ thick between said movable cutting blade and said stationary butting blade; and
wherein after cutting, a return spring causes said movable cutting blade to return from said cut position to said feed position allowing plastic drywall trim to be fed through said trim guide, said trim guide being positioned so that said plastic drywall trim feeds between said movable cutting blade and said stationary butting blade.
