The Chinese Factory Specializes in Customizing Air Shafts For Industrial Machines

Expanding shafts are also known as expansion shafts, flatulence shafts, inflatable rollers, inflation shafts, pressure shafts, etc. The inflatable shaft is used in conjunction with the magnetic particle brake, and the main body is made of high-quality steel pipe with hard chrome plating on the surface; Aluminum convex key, flexible and telescopic; Equipped with high-quality rubber liner and fast exhaust nozzle, with good sealing effect and long service life; The inflatable shaft can be removed separately from the shaft head, which is easy to maintain. The rewinding and unwinding reels of coating, slitting, printing, laminating, papermaking, bag making, plastics and other related machinery can effectively improve work efficiency.

Classification of inflatable shafts:
Specifically, it can be divided into convex key inflatable shaft, tile inflatable shaft, through-key inflatable shaft, slip inflatable shaft, and convex cantilever inflatable shaft.

Structure of the air shaft:
The air shaft consists of three main parts: the shaft body, the bearing, and the hermetically sealed device.

• The shaft body is the main part of the air shaft, which is composed of the air shaft tube, the shaft core and the shaft head. Air shaft tubes are usually made of aluminum alloy or stainless steel, which has high strength and corrosion resistance. The shaft core is the core part of the air shaft, which consists of an air shaft tube vented internally and a shaft head with a bearing on the outside. The shaft head is usually made of cast iron or steel,which has high hardness and wear resistance. Straight of the shaft core.The diameter and length are determined according to the occasion of use and the required load-bearing capacity.
• The bearing is an important part of the air shaft, which is used to support the rotational motion of the shaft core. Bearings are usually composed of ball bearings or roller bearings, which can withstand large radial and axial loads, and the outer and inner diameters of the bearings are determined according to the size of the shaft core and the occasion of use.
• The airtight sealing device is used to ensure the internal airtightness of the air expansion shaft. It usually consists of an airtight sealing ring and an airtight gasket, which can effectively prevent gas leakage and external impurities from entering. The material and construction of the hermetic seal is determined according to the type of gas used and the pressure.

Features of the expand shaft:
1. Short inflation operation time: the separation and placement of the inflatable shaft and the paper tube can be completed in only 3 seconds, and the paper tube can be tightly engaged without disassembling any parts on the end side of the shaft.
2. The paper tube is simple to place: with the action of inflation and deflation, the paper tube 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 high hardness steel is used to increase the bearing weight.
4. High economic efficiency: the design of the shaft is a special function, and it can be used in all kinds of thick, thin, wide and narrow paper tubes.
5. Simple maintenance and long use time: Although the inflatable shaft is a mechanical accessory, each part in its own structure has fixed specifications and can be used interchangeably, making it easy to maintain.

The working principle and use of the air expandable shaft:
The air shaft is better than the general shaft, but the good thing is that the unloading does not need to remove the entire shaft. After directly deflating, the material can be taken away, because its width is not large, so the operation is more convenient. This is also the inflatable shaft chosen for many machines with light weight and small width. 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, and the external parts (such as the round paper tube) need to be locked.
As long as the inflatable handle is inflated against the air nozzle on the inflatable shaft, the key bar will protrude against the external parts (such as the round paper tube), when the paper tube needs to be loosened, press the sliding air core on the air valve with your hand to deflate, the key bar will return to its original appearance, and the external parts (such as the round paper tube) can be taken out.

Areas of use of rewinder shaft:
The air shaft can be used in a wide range of applications: all machines with winding, unwinding and slitting can be used for the air shaft.
Suitable for printing equipment: drying machine, flexo printing machine, gravure machine, trademark printing machine and so on.
It is suitable for other machinery and equipment: coating machine, leather machine, setting machine, embossing machine, slitting machine, die-cutting machine, rewinding machine, rewinding machine, paper tube 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 and other related machinery.

How to find a reliable Chinese factory custom inflatable shaft? The process of Chinese factory PRE to customize the inflatable shaft is as follows:
1. If the previous inflatable shaft is broken and you need to replace the new inflatable shaft, you can take pictures or videos of the old inflatable shaft to PRE.
2. If there is a drawing of the inflatable shaft, you can directly send the drawing to the PRE sales staff, and at the same time, you can provide your own parameter requirements to the PRE, and the sales staff will give the drawings and specific parameters to the technician for analysis and get the results.
3. Send the quantity of the inflatable shaft that needs to be customized to the PRE factory.
4. After the analysis, the sales staff of the PRE factory will give you a reply whether it can be customized and make a quotation for the product.
5. After the quotation of the product, if you need to inquire about the freight, the PRE sales staff will help contact the shipping company and estimate the freight.
6. After the goods are shipped, PRE will prepare the required information to assist in customs clearance.
