What Are The Precautions For Inflatable Shaft Components?

Definition of inflatable core shaft:
The inflatable shaft is a special winding and unwinding shaft, that is, the shaft that can protrude on the surface after high-pressure inflation, and the shaft that quickly retracts the surface part after deflation is called the inflatable shaft. Its names are diversified, also known as pneumatic shaft, expansion shaft, flatulence shaft, inflatable roller, inflatable shaft, pressure shaft, inflatable roller, etc.

How the air inflatable shaft works:
Although there are many names for inflatable shafts, they work on the same principle. The inflatable shaft and inflatable sleeve are extremely convenient and fast to use, only need to provide their own air source, the air pressure is controlled in the range of 6-8kg/cm2, when the external parts (such as the round paper tube) need to be locked, as long as the air gun is inflated on the air nozzle on the inflatable shaft, it can be completed, and the external parts (such as the round paper tube) can be taken out when the paper is unloaded.

Five precautions for inflatable shaft components:
1. Whether there is a short circuit in the output of all PLCs of the inflatable shaft.
2. Whether the power supply inlet of the machine tool of the inflatable shaft is reliably grounded, and whether the specifications of the grounding wire meet the requirements.
3. Whether the layout of the power line and the signal line is reasonable, and whether the cable connection is correct and reliable.
4. Whether the connecting wire between the electrical cabinet and the equipment of the inflatable shaft is damaged, and whether there is crackage or damage at the bend of the cable.
5. Whether the grounding of the signal shield wire is correct, whether the wiring on the terminal board is firm and reliable, and whether the system grounding wire is connected reliably.

Advantages of inflatable shafts:
1. The inflation operation time is short, and the separation and placement of the inflatable shaft and the paper tube can be completed in only 3 seconds, and there is no need to separate any parts on the end side of the shaft to tightly occlude with the paper tube.
2. The paper core is simple to place: 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: according to the actual needs of customers, the size of the shaft diameter can be determined, and the use of high hardness steel to increase the bearing weight.
4. High economic efficiency: the design of the inflatable shaft is a special function, and it 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 interchangeable and convenient, making it easy to maintain.

Inflatable shaft function and correct use method:

• Function: 1. Wide application: inflatable shaft as an independently designed part, from 1 inch --- 12 inches, the length and size are determined by the actual needs of customers, where there are strip printing, rewinding, coating, laminating, bag-making, papermaking and other work equipment or other related center coiling machinery, can be applied to the inflatable shaft.

　　2. Cost-effective and efficient: The design of the shaft is designed for the actual work needs, and it can be applied to various types of coils such as thickness, thinness, width and narrowness.
　　3. Long use time and simple maintenance: although the inflatable shaft is a mechanical accessory, every part in its own structure has fixed specifications and can be used interchangeably to make it easy to maintain.
　　Fourth, a single fitting: the inflatable shaft is a single spare part of the winding and unwinding machinery, each part in its structure has a fixed size, can be decomposed and combined, so that the maintenance is convenient, durable and durable.
　　5. Professionalism: There are professional engineering and technical personnel to conduct market research on the design, installation and use of inflatable shafts.
　　6. Large carrying capacity: the inflatable shaft can be designed according to the actual model, using high-quality steel to increase the carrying capacity. For example, steel materials can be used for bearing weight of more than 1 ton.
　　7. Short operation time: separating and placing the coil can be completed with only 2 seconds of inflation and deflation action, and the placement of the coil is simple and convenient, safe and applicable. All machines and equipment for winding and unwinding can be applied to inflatable shafts. The length of the inflatable shaft can be up to six meters or more, and the shortest can be several hundred millimeters, all according to the customer's needs.
　　8. The key inflatable shaft expands a single key bar, and the fulcrum spreads to each key bar to balance the force, which can be applied to items with heavy mechanical winding capacity.

• How to use: The cantilever inflatable shaft is better than the general inflatable shaft, but it is good that the whole shaft does not need to be removed for the next discharge. After directly deflating, the material can be taken away, because its width is not large, so it is more convenient to operate naturally. This is also the inflatable shaft chosen for many machines with light weight and small width. As long as the inflatable handle is inflated against the air valve on the inflatable shaft, the sliding air core on the air core can be deflated, and the key bar will return to its original appearance.

Now all machines with winding, unwinding, and slitting can use inflatable shafts. The inflatable shaft can be equipped with inflatable shaft in concave plate machine, trademark printing machine, coating machine, embossing machine, slitting machine, die-cutting machine, rewinding machine, bag making machine, laminating machine and many other equipment. Next, I will introduce to you the installation method of the convex key inflatable shaft：
1. When installing the air expansion shaft, it is necessary to make sure that the compressor that controls the gas pressure is in a stable state, and the filter is directly installed between the compressor and the expansion shaft to prevent impurities from blocking the air pipe and causing air leakage.
2. Air should enter vertically to prevent damage to the valve;
3. When exhaust gas is exhausted from a key type inflatable shaft (the inflatable shaft of the key lever), a standard exhaust port must be used. The use of sharp hammers and other tools is prohibited. Avoid causing air leakage;
4. Install pressure gauge and pressure control device, and the pressure must be controlled within the range of 3-8kg/cm;
5. When replacing the valve of the convex key inflatable shaft (main rod inflatable shaft), a socket wrench must be used. If an internal failure occurs, it needs to be disassembled and repaired, please consult professional maintenance personnel, do not disassemble, so as not to cause unnecessary losses;
6. The convex key inflatable shaft (key rod inflatable shaft) should be placed carefully to avoid damaging the air valve.
