Why Do Many Machines Have Air Shafts

An air expanding shaft is a mechanical transmission device that can control the transmission capacity of the shaft by inflating and deflating. Generally speaking, the outer diameter of the inflatable shaft will be enlarged after inflation, and then the inflatable shaft will be sleeved into the coil, and the coil will be tightened.

Advantages of pneumatic expanable shafts:
1) Stability: The size of the outer diameter of the inflatable shaft can be adjusted by inflation and deflating. When the diameter of the inflatable shaft becomes larger and the work is done in conjunction with the tension controller, the machine can achieve a very high level of stability when winding and unwinding.
2) Adaptability: Because of the various types of inflatable shafts, it can be used for many different types and thicknesses of coils, paper, and film. In addition, different inflatable shafts can cope with different production requirements, from lightweight paper cutting to complex composite materials. In particular, for different widths and different paper types, only the corresponding inflatable shaft needs to be replaced, and the inflatable shaft can be used for different production tasks.
3) The process of inflation and deflation is very convenient: as long as the user provides his own air source, the air pressure is controlled in the range of 6-8kg, when the reel core needs to be locked, as long as the air gun is inflated against the air nozzle on the inflatable shaft, it can be completed, and when the reel core needs to be loosened and discharged, press the sliding air core on the air nozzle by hand to deflat.
4) Simple maintenance: each part in the structure of the inflatable shaft itself has a fixed specification and can be used interchangeably, so it is very convenient for the inflatable shaft to be repaired and maintained, so for the consumable small parts, you can buy more from the manufacturer as a backup according to your own needs.
5) Relatively low noise: Compared with the traditional paper processing machine accessories, the inflatable shaft runs more smoothly, has stronger shock resistance, and has less noise. This is extremely important in the manufacturing process, which can not only improve the production efficiency of operators, but also reduce noise pollution in the workplace, improve the production and working environment, and be more humane.

Classification of inflatable shafts:
Inflatable shafts are divided into key inflatable shafts, plate inflatable shafts, multi-bag inflatable shafts, and so on. The expansion part of the plate inflatable shaft is the whole plate, the fulcrum is evenly dispersed, and the force is uniform, and the expansion height can reach 4mm to 5mm. For example, the diameter before expansion is 74mm to 75mm, and the diameter after expansion can reach 78mm to 79m; Key inflatable shaft: The expansion part is a key bar, usually the unilateral expansion height can reach 5mm to 6mm, such as the diameter before expansion is 74mm to 75mm, and the diameter after expansion can reach 79mm to 82mm.

Current areas of application of inflatable shafts:
The use of inflatable shaft is very wide, and all machines with winding, unwinding and slitting can be applied to inflatable shafts, even including light metal industries. For example, the inflatable shaft is mainly suitable for printing equipment: drying machine, flexo printing machine, gravure machine, trademark printing machine, etc.; Other machinery includes: coating machine, leather machine, setting machine, embossing machine, slitting machine, die-cutting machine, rewinding machine, paper tube machine, bag making machine, laminating machine, laminating machine, film blowing machine, foaming machine, laminating machine, embossing machine, paper machine, non-woven machine, cloth inspection machine, hot stamping machine, battery equipment and other related machinery supporting the use.

The future development trend of the inflatable shaft:
In terms of future market trends, the inflatable shaft will be lighter, more miniaturized and more automated. Although artificial intelligence is developing rapidly and robots are becoming more and more flexible, the opportunity for the inflatable shaft to be replaceable is relatively small, because although the inflatable shaft is only a small accessory on the machinery, the specifications are generally 1 inch, 1.5 inches, 2 inches, 2.5 inches, 3 inches, 6 inches, 8 inches, 10 inches, and 12 inches, but they are generally customized according to their own needs, so the inflatable shaft will still be more and more widely used in various types of processing industries and become its indispensable rotating machine accessories.
