A paper feed head air path mechanism

Abstract

The utility model provides a kind of paper feeding head gas path mechanism, including gas distribution and gas distribution valve, gas distribution and gas distribution valve are respectively connected into positive pressure gas and negative pressure gas, positive pressure gas is divided into two ways, one of which positive pressure gas enters three-way pipe through presser foot blowing main gas pipe, after shunting, enters presser foot blowing group through presser foot blowing branch pipe, realizes presser foot blowing, another positive pressure gas enters three-way pipe through paper loosening blowing main gas pipe, after shunting, enters paper loosening blowing group through paper loosening blowing branch pipe, realizes paper loosening blowing;Negative pressure gas is divided into two ways, one of which negative pressure gas enters paper separating suction nozzle group through paper separating suction main gas pipe, realizes paper separating suction, another negative pressure gas enters paper feeding suction nozzle group through paper feeding suction branch pipe, realizes paper feeding suction, the utility model layout is simple, pipeline is straight-through, corner is few, dust is not easy to accumulate in pipeline, structure is reasonable, easy to assemble and maintain.
