The invention discloses a pneumatic
strapping machine capable of preventing tape falling, and belongs to the technical field of packaging machinery. The
machine comprises a
strapping machine core anda tape feeding and withdrawing tightening mechanism; and the
strapping machine core comprises a base, a pressing tape
cutting mechanism and a linkage air
cylinder set, wherein the pressing tape
cutting mechanism is movably arranged on the base and driven by the linkage air
cylinder set. According to the machine, the technical scheme that the pressing tape
cutting mechanism is driven by the linkageair
cylinder set is adopted to replace the technical scheme that in the prior art, the pressing tape cutting mechanism is driven by a motor and a
cam set drive, and moreover, an auxiliary mechanism required for driving the pressing tape cutting mechanism by adopting the motor and the
cam set is cancelled, so that mounting hole sites formed in the base are greatly reduced, the
machining difficultyof the base is reduced, and more accommodating space can be vacated in the base; and correspondingly, the length size of the strapping machine core is shortened on the whole, so that the structure weight of the machine core is reduced, and the strapping machine can be applied to more special industries and special application scenes.
