Air expansion shaft, is the shaft mainly through the formation of inflatable, is the winding, unwinding tools. It has a relatively short time to inflate, or even only 3 seconds to complete the separation and placement of the air expansion shaft and paper tube. The placement of the paper tube is actually very simple, it mainly acts as the action of inflation and deflation, and can move or fix in any position on the axial surface of the paper tube.At the same time, the bearing capacity of the air expansion shaft is also very large, the size of the shaft diameter can be determined according to the needs of customers, and steel with higher hardness is used, so that the bearing weight is greatly increased. In the design of the air expansion shaft is also very special, because the thick, thin, wide, narrow paper tube can be applied. Although it is only an accessory on the machinery, it has the specified specifications in the structure, so it can be used interchangeably, and maintenance is also very convenient.

Everything needs maintenance to extend its useful life. In fact, the maintenance of the air expansion shaft is very simple, because the service life of the airbag inside the air expansion shaft is very long, so the probability of damage to the air expansion shaft itself is very small. This not only reduces the outage rate in the production process, so that the bad products are greatly reduced, thereby not only reducing the production cost, but also improving the service life of the air expansion shaft.
