Abstract
The utility model discloses a pneumatic knife, which comprises a cylindrical body. An air inlet shaft is arranged on the top portion of the cylindrical body, an air exhausting shaft is sleeved on the outer side of the air inlet shaft, and a flow diverting device is disposed at the lower end of the air inlet shaft which is communicated with an air passage of an air cylinder body via the flow diverting device. The air cylinder body is linked with a cutting knife via a transmission device. The pneumatic knife has simple structure, adopts the flow diverting device to divert one air passage into two air passages in the air cylinder body to form a cyclical passage, realizes cyclical reciprocating movement of a piston by controlling air inletting of the two air passages so as to drive the cutting knife to perform cutting action, has convenient utilization and high cutting speed, greatly enhances production efficiency with high cutting accuracy, guarantees product quality with smooth, flat and even cutting marks, additionally has wide application range, and as indicated by experiments, is capable of cutting various leather materials, paper boards or plastic boards with a thickness under 8mm.
