The Subtleties Of The Air Shaft

The inflation shaft, as its name implies, is made by inflating the air nozzle of the air-expansion shaft through an air gun, from the United States. After the high pressure is inflated, the surface protrudes from the shaft, mainly for winding and unwinding. It is widely used in various industries such as slitting, printing, rewinding, coating, laminating, bag making, paper making, etc. with its own advantages. The specific advantages are as follows:

1, cost-effective

The shaft design of the inflation shaft is very user-friendly and has a strong applicability. Whether it is thick, thin, wide or narrow, it is useful for all types of coils.

2, simple maintenance

Although the mechanical axis is an accessory, the expansion shaft has a myriad of parts in its own construction. Each part has a fixed size and can be used. Therefore, maintenance is also very convenient.

3, easy maintenance

The inflation shaft is a single fitting for the receiving and unwinding machinery. Although each part in the structure has a fixed size, it can be disassembled and combined, and the maintenance is also very convenient and durable.

3, large carrying capacity

The air-expansion shaft can be designed according to the actual model, using high-quality steel, can increase the bearing capacity to a certain extent, and can withstand at least 1 ton of weight.

4, short working hours

The expansion shaft is very short whether it is separating or placing the coil, and it takes only 2 seconds to complete the inflation and deflation.

The largest structural feature of the inflation shaft is that it has a continuous undivided shape, and the slip shaft is usually connected by a segmented inflation unit. The outer layer of the inflation shaft is an inflatable sleeve, and both ends of the inflation sleeve are sealed by a sealing ring. The inflatable sleeve is internally wrapped with a key strip, an inflatable sheet, a central shaft body, and the like. The air pressure enters from both ends of the inflation shaft, and the pressure can be controlled to control the protrusion and contraction of the key strip. When the key strip or the expansion tab protrudes, the inflation sleeve has a frictional force, and the animal material is wound up.

 Since the inflation axis is continuous, the generation and disappearance of the frictional force on the inflatable sleeve are uniform, and it is impossible to control the friction of a single point, so the inflation shaft has no slip function. The inflation shaft can have numerous protruding points, and the frictional force can be designed according to the needs. Because of this, the inflation shaft is more suitable for the winding of materials with relatively large areas and relatively high quality.
