Description

Reinforcing steel bar binding machine for cutting wires by wire winding inner sleeve Technical Field The invention relates to the field of reinforcing steel bar binding machines, in particular to a reinforcing steel bar binding machine which is cut by a wire winding inner sleeve. Background The reinforcing bar binding machine has the advantage of binding reinforcing bars efficiently, and is widely used in the field of constructional engineering. The existing reinforcing steel bar binding machine comprises a wire feeding mechanism, a braking mechanism, a wire guiding mechanism (comprising a looping plate and a guider), a wire winding mechanism and a wire cutting mechanism, wherein the wire feeding mechanism is used for guiding an iron wire to the looping plate, the iron wire is wound in a looping mode under the action of the looping plate and the guider, the wire cutting mechanism is used for cutting off the iron wire, and the wire winding mechanism is used for tightening the iron wire wound on the steel bar. Above-mentioned filament cutter of strapper is the structure that sets up alone, sets up this filament cutter alone and not only can occupy the inner space of steel bar strapper, makes the whole mechanism of steel bar strapper complicated simultaneously, has increased the manufacturing cost of strapper.
