HENLI air  feeder consists of main body, guide rail and feeding base to form the overall skeleton, in which the main body includes switches, guide rods, speed high speeders, fixed splints, moving splints, etc.; the guide rails contain moving splints, the feed base contains feed rollers, and the material Wheel, feeding length fine adjustment screw.

In the actual assembly, the main part of the air feeder needs to be fixedly installed on the workbench on the side of the punch die. The main body is equipped with a floating bar. Above the floating bar, there is a guide plate fixed at one end of the punch die, and the guide plate is on the punching die. Press and release the floating rod under repeated motions up and down.

Structure of Air feeder

When the air feeder operates, the material is first feed by the feed roller, and then passes through the block wheel, moves the plywood, and fixes the plywood and finally is placed on the stamping die platform so that the upper die can punch it.

In the initial state, the moving splint is close to the fixed splint; when the punching machine is in operation, the upper die punches downwards and drives the guide plate to move downwards together, the guide plate presses the floating rod and generates a downward pressure, and the floating rod transfers the pressure signal to the relay , The time relay first controls the lift cylinder to move the clamp downwards. The clamp material allows the material to pass with the clamp. After the upper mold completes a work, the upper mold moves upwards, and the guide board moves upwards to guide the board to relax. In the floating bar, the floating bar will release the signal and transmit it to the time relay through the control button. The time relay will bring the plywood to move and return to the initial position. At this moment, the moving clamp will release the material. When the punching machine moves, the upper mold punches down, and the floating bar transmits the signal to the relay again, repeating the previous work, and so on.

classification of air feeders

The air feeder is divided into the following types:

  1. Standard type: feed length (width) 0-450mm, feed thickness 0.1-3.2mm, can send material types: metal, paper bag, plastic; can send material shape: round, triangle, protrusion; special attachment: AF -5C and above accessories mount buffer.
  2. E-type solenoid valve: It is suitable for the case where the stroke of the punch is too short or too long. The standard type R-relief solenoid valve must be installed under precise feeding conditions. The solenoid valve can be used to loosen the clamp to correct the error.
  3. R-type relaxation solenoid valve: suitable for the punch under the trip too short or too long distance feeding, and the need for high precision feeding, solenoid valve can be used to relax the clamp to correct the error
  4. new powerful type: suitable for automated processing of thicker materials. This machine adopts a new type of pneumatic buffer to eliminate the vibration of fast feeding. The splint uses a multi-cylinder under pressure slider-style splint. The grinding, simple operation, high stability, accurate and accurate feeding.
