Why Does The Air Shaft Adapter (inflatable Drum) Increase The Outer Diameter Of The Pneumatic Expander Shafts And The Transmission Roller?

Definition of core adaptor:
Inflatable sleeve clamp, also known as air expansion shaft, air shaft, air pressure shaft, air expansion sleeve, inflatable sleeve, air pressure sleeve, air expansion sleeve clamp and air pressure sleeve clamp. It is a special rewinding and unwinding shaft, that is, the shaft that can be inflated on the surface after high-pressure inflation, and the shaft sleeve that quickly retracts the surface part after degassing.
As long as the user provides their own air source, the air pressure is controlled in the range of 6-8 kg, when the drum core needs to be locked, as long as the inflation handle is inflated to the air nozzle on it, it can be completed, and when the drum core needs to be loosened and discharged, the sliding air core on the air nozzle can be deflated by hand.

The structure of the inflatable sleeve is as follows:
The air sleeve is mainly composed of front sleeve, rear sleeve, cylinder, inner tube, air bag, convex keyboard and other parts. The expansion set is made of high-quality aluminum, with oxidized surface, high-quality airbags and fast inflators. Good sealing effect, long service life and easy maintenance. Advantages: light weight, easy loading and unloading.

Common product specifications of inflatable sleeve clamps:
It is divided into key inflatable sleeve and plate inflatable sleeve.
Commonly used specifications are: 3 inches to 6 inches, 3 inches to 8 inches, 3 inches to 10 inches, 3 inches to 12 inches. After inflation, the diameter rises by 8mm. The length is 200mm, 250mm, 300mm, 400mm, 500mm, etc. (The length can be ordered according to customer needs, and the length is not limited)

Common technical parameters of inflatable sleeve clamps:
The outer diameter of the main body of the inflatable sleeve: Φ150mm, the outer diameter of the action is Φ155mm.
Applicable paper tube: Φ149-153mm, 201-205mm, 252-256mm, 302-305mm.
Main length: 200mm, 250mm, 300mm, 400mm, 500mm, etc.

When inflatable shafts and drive rollers need to use inflatable sleeves:
The inflatable sleeve clamp is also called the inflatable drum, which is used on the inflatable shaft and the transmission roller, and is used instead of a larger retracting and unwinding shaft when doing rewinding and discharging, for example, the shaft used on the machine is a 3-inch inflatable shaft or a smooth roller, and suddenly there is an increase in new materials, and a 6-inch inflatable shaft is needed, and you don't want to do a 6-inch inflatable shaft, in this case, you can use a 3-turn 6-inch sleeve clamp.

Installation of the inflatable sleeve clamped on the inflatable shaft or on the transmission roller:
The inflatable sleeve clamp is a middle through hole, which can be used on the inflatable shaft or the transmission roller, which can be made into a mechanical type or can be made into a separate inflatable one, if it is used on a smooth transmission roller, it is necessary to add expansion rings at both ends of the inflatable sleeve clamp to play a fixed role; If you use it on an inflatable shaft, you can make a ring on one side or both.

How to determine the right inflatable sleeve according to the inflatable shaft:
The inflatable sleeve clamp also has a plate plate type and key strip type, the inner diameter is determined according to the inflatable shaft, the outer diameter is determined according to the current paper tube, the inflatable shaft is relatively short below 500-600 mm, a shaft with 1 can be, if the inflatable shaft has reached 1 meter or 2 meters, a shaft is best equipped with 2 or 3 clamps.

Learn more about plate type inflatable sleeve clamps and key strip type inflatable sleeve clamps:
1) Plate inflatable sleeve clamp: also known as slatted inflatable shaft, six-piece inflatable shaft, tile inflatable shaft, etc.
features: aluminum alloy tile, flexible expansion and contraction, equipped with rubber liner and fast inflatable exhaust nozzle, good sealing effect, long service life, can be disassembled shaft head, easy maintenance, after inflation, the expansion part is a plate, usually the expansion height can reach 4mm to 5mm (such before expansion 3-inch diameter is 74mm-75mm and after expansion diameter can reach 78mm-79mm), 3-inch plate inflatable shaft, usually use coil inner diameter of 76mm.
Applicable scenario: The plate inflatable shaft expands the whole plate, the fulcrum is evenly dispersed, and the force is uniform, which can be applied to machinery with high winding precision or lighter winding items, and is used in the case of high roundness requirements for paper tubes or surface winding and unwinding, which can effectively improve the difficult workforce and product quality.
2) Features of keybar inflatable sleeve clamp:

1. Short inflation time: It only takes 3 seconds to complete the inflation and deflation of the inflatable shaft and the paper core, and it can be tightly engaged with the paper core without disassembling any parts on the shaft end side.
2. Easy paper core placement: with the action of inflation and deflation, the paper core can be moved and fixed in any position on the shaft surface.
3. Large bearing weight: The size of the shaft diameter can be determined according to the actual needs of customers, and the use of high hardness steel can increase the bearing weight.
4. High economic efficiency: The shaft is designed as a special function and can be used for all kinds of thick, thin, wide and narrow paper tubes.
5. Easy to maintain and long to use.
