Cantilever air shaft for Die-cutting machine and mask making machine

The cantilever air shaft is better than the general air shaft because it does not need to remove the whole shaft in each discharge. The material can be taken away after direct venting, because its width is not large, so the natural operation is more convenient. This is also the air shaft used by many machines with light receiving weight and small width. air shaft, inflatable sleeve is very convenient and fast to use, only need to provide their own air source, air pressure control in the range of 6-8kg/cm2, need to lock the external parts (such as circular paper tube), as long as the inflation handle against the gas nozzle on the air shaft can be completed, the key bar will be protruding against the external parts (such as circular paper tube), need to relax the paper unloading, By pressing the sliding air core of the air nozzle with your hand, the key will return to its original appearance, and the external parts (such as the circular paper tube) can be extracted.
