Product Description

Description

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.

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.

Under what conditions do you need to use a slatted air shaft?
a. When the product needs to be wound in strips, and the width of a single wound product is narrow;
b. When the product requires a higher true circle;
c. When the roll paper core or other raw material roll used in the product has a thin wall or is of poor quality and is easily deformed.
