3inch Rewinder Air Shaft

Description

The air expansion shaft is very convenient and fast to use. The user only needs to provide the air source, and the air pressure is controlled within the range of 6-8 kg. When the paper cylinder needs to be expanded, it can be completed as long as the air rod inflates towards the air nozzle on the air expansion shaft. When the material needs to be unloaded, it can be deflated by pressing the air core on the air nozzle with your hand, and the inflation and deflation can be completed in 2 seconds.

Introduction:

The contraction part of the plate type inflatable shaft is the plate, usually the expansion height can reach 4mm to 5mm, for example, the diameter before contraction is 74mm to 75mm, and the diameter after contraction can reach 78mm to 79m. The special contraction height is separately required and determined by the customer. The 3 inch plate type inflatable shaft usually uses a coil with an inner diameter of 76mm. The plate type inflatable shaft shrinks from the entire plate, the fulcrums are evenly dispersed, and the force is average. It can be used for machinery with higher winding precision or winding Light items.
