The manufacturer provides inflatable roller, key bar type inflatable shaft, tile type inflatable shaft, which can be processed and customized as accessories for winding, unwinding, and slitting machines

What are the differences between key type inflatable shaft and plate type inflatable shaft

Key type inflatable shaft: also known as convex key inflatable shaft, key bar inflatable shaft, convex claw inflatable shaft, claw key inflatable shaft, and other names, but the working principle is the same.

Characteristics: The expansion part is a key bar, usually with a single side expansion height of 5mm to 6mm. For example, the diameter before expansion is 74mm to 75mm, and the diameter after expansion can be 79mm to 82mm. Special expansion height is required separately. 3-inch keyed inflatable shaft, usually using a coil with an inner diameter of 76mm, The key type inflatable shaft expands into a single key bar, and the fulcrum spreads to each key bar to balance the force. It is suitable for mechanical winding of items with heavy load-bearing capacity, such as cloth, paper, thin film printing, leather composite materials, etc., mainly determined according to actual needs.

Plate type gas expansion shaft: also called plate type gas expansion shaft, Flat noodles type gas expansion shaft, six piece type gas expansion shaft, tile type gas expansion shaft, etc., but the working principle is the same.

Characteristics: The expansion part is a plate, usually with a height of up to 4mm to 5mm. For example, the diameter before expansion is 74mm to 75mm, and the diameter after expansion can be 78mm to 79m. The special expansion height is specified by the customer. The 3-inch plate type air expansion shaft is usually used, and the inner diameter of the coil is 76mm. The expansion of the plate type inflatable shaft causes the entire board to expand, with evenly distributed support points and uniform force. It can be used for high-precision machinery or lighter items, such as electronic materials, battery materials, foam cotton, plush paper towels, non-woven fabrics, etc., mainly determined according to actual needs.
