The plate-type air expansion shaftexpands the entire plate, the fulcrums are evenly dispersed, and the force is even. It can be used for winding precision machinery or lighter items, such as: air expansion shaft is mainly suitable for printing equipment: Exposure machine, flexo printing machine, gravure machine, trademark printing machine, etc.

 The plate-type air expansion shafthas good sealing effect, long service life, detachable shaft head, and convenient maintenance. After inflation, the unilateral expansion height can reach 5mm to 6mm. For example, the diameter before expansion is 74mm to 75mm, and the diameter after expansion can reach 79mm to 82mm. Special expansion height is required separately. 3 -inch keyed air expansion shaft, usually use coiled tube inner diameter 76mm.

The air expansion shaft is easy to use and rewinds freely. It only takes 2 seconds to inflate. It can complete the tight fixation of the air expansion shaftand the reeling tube to achieve a good winding effect; similarly, it only takes 2 seconds to deflate. The air expansion shaftcan be separated from the roll tube, so that the air expansion shaftcan be easily taken out from the roll tube. The air expansion shaftmatching clamp is suitable for coiled tubes with larger inner diameters. Equipped with a safety chuck, the air expansion shaftand the machine can be easily assembled and assembled freely, saving time, effort and cost. 

The development of the air expansion shaftis based on the original traditional shaft, and after continuous technological innovation, it has been sublimated into a modern air expansion shaft, which has brought the value of the above related machines to a new level. The plate-type air expansion shaftmainly uses the principle of expansion and contraction to achieve the air expansion shaft to expand and tighten the paper tube to collect the material, and discharge the material after deflation. The hose from Taiwan has good shrinkage performance and is not easy to blast. Suitable for items with larger inner diameter of the coil.
