Air expanding shaft Product Purpose:
It is applicable to winding and unwinding shaft of the related machines in coating,cutting,printing,compounding,paper making,bag making,plastic items,specially the occasion of the high-efficient roundness required or surface winding and unwinding of the paper tube.Moreover,it also can improve efficiency and quality of the products.

Features: The expansion part are leaves, usually the height of the expansion can reach 4mm to 5mm, such as the diameter before expansion is 49mm, the diameter after expansion can reach 53mm to 54mm, special expansion height can be customized by customers,2-inch leaf type air shaft is with a coiled tube inner diameter of 50mm. The plate type air expansion shaft expands from the whole plate, the fulcrum is evenly distributed, and the force is uniform. It can be applied to machines with high precision of winding or lighter articles, such as electronic materials,battery materials,foaming, cotton, plush,paper towels,non-woven, etc., mainly based on actual needs.

Leaf type air shaft feature:

1. The plate-type inflatable shaft is a kind of bai and du inflatable shafts. It mainly uses the expansion of zhi slats and is distributed on different fulcrums of dao to achieve the function of evenly cutting and rewinding under the force of shu.
2. The expansion height of the plate-type inflatable shaft is 4~5mm, the overall volume of the slat-type inflatable shaft is relatively large, and the length can also be adjusted according to requirements.
3. Scope of application: It can rewind electronic materials, cloth, paper towels, foam cotton and other materials of moderate quality, and the precision of the plate type inflatable shaft is high.
