A high frequency perforating device

Abstract

The utility model discloses a high -frequency punching device, including base, the movable punching knife device is installed on base upside, the fixed knife is installed on base downside, and the movable punching knife is equipped on the top of fixed knife, movable punching knife device includes movable punching knife, and the outer periphery of the cutter bar of movable punching knife is sleeved with reset spring, and the outer periphery of reset spring is equipped with the installation pipe, movable punching knife cooperation fixed knife cutting packing bag is driven by the compressed gas that enters from the air inlet pipe, and after the compressed gas enters from the air inlet pipe and drives movable punching knife, discharges from the air vent of installation pipe side, and the solenoid valve of control compressed gas opening and closing is connected to the air inlet pipe. The utility model discloses through the compressed gas from the air inlet pipe, discharges from the air vent of installation pipe side, avoids the resistance that the compressed gas remains stagnation installation pipe inside produces to the time of reset spring movable punching knife spring reset thereby, thereby realizes the technical purpose of high -frequency punching.
