Description
The scope of application of the key type inflatable shaft: the key strip type inflatable shaft expands to a single key strip, and the fulcrum spreads to each key strip to balance the force. It is suitable for mechanical rewinding of items with heavier load, such as: cloth, Paper, film, printed matter, leather, composite materials, etc., suitable for coating, slitting, printing, rewinding, laminating, paper making, bag making, plastics and other related machinery reels, which can effectively improve work efficiency.

Introduction:
Features of inflatable shaft:
1. The inflating operation time is short, the inflatable shaft and the paper tube can be separated and placed in only three seconds to complete the inflation and deflation, and there is no need to separate any parts on the end of the shaft to tightly engage the paper tube.
2, the paper tube is easy to place. With the action of inflating and deflating, the paper tube can be moved and fixed at any position on the axis.
Third, the bearing weight is large. The shaft diameter can be determined according to the actual needs of customers and the actual pressure bearing weight can be increased by using high-hardness steel.
3, high economic efficiency: The shaft is designed for special functions, and it is used for all kinds of straight pipes with different thickness and width.
Fifth, the maintenance is simple, the use time is long, the inflatable shaft is a single part, and each part in the structure has a fixed specification and can be used universally to make it maintenance.

Features:
Inflatable shafts have a wide range of uses. Any machine that has winding, unwinding, and slitting can be applied to inflatable shafts, even in the light metal industry. It has the following characteristics:
1: The inflating operation time is short. The inflatable shaft and the paper tube can be separated and placed in only 3 seconds to complete the inflation and deflation. There is no need to separate any parts on the shaft end to tightly engage the paper tube.
2: The paper tube is easy to place: the paper tube can be moved and fixed at any position on the axis by the action of inflation and deflation.
3: Large load-bearing weight: The size of the shaft diameter can be determined according to the actual needs of customers, and high-hardness steel is used to increase the load-bearing weight.
4: High economic efficiency: The shaft is designed for special functions, and can be used for all kinds of thick, thin, wide and narrow paper tubes.
5: Simple maintenance and long use time: The inflatable shaft is a single part, and each part in its structure has a fixed specification, which can be interchanged and used, making it easy to maintain.
Inflatable shafts are divided into convex key inflatable shafts, tile-type inflatable shafts, mechanical inflatable shafts, and surface airbag inflatable shafts.
