AIR KNOCKER (DIRECT TYPE)

The Air knocker series (direct impact type) are unique equipment in which the force of compressed air causes the piston to strike the hopper wall surface directly and energetically, which eliminate the adhesion or clogging of powder. While the indirect impact type strikes the mounted knocker base at a predetermined position, the air knocker is used in wider range of applications on your idea, such as striking the moving object and striking the target with the knocker itself moved. It is also used like the indirect impact type.

Operating principle of Air knocker

  1. The compressed air flowed into the knocker is first supplied to the valve chamber to depress the mushroom valve and then is stored in the accumulator.
  2. When the three-way valve is actuated to exhaust the air from the valve chamber, the compressed air in the accumulator moves the mushroom valve upward.
  3. When the mushroom valve moves, the compressed air in the accumulator depresses the piston energetically, which strikes the base surface. That impact force eliminates the adhesion or blockage of powder.
