Inflatable shafts include split plate type inflatable shafts, key strip type inflatable shafts, full-length key type inflatable shafts, cantilever type inflatable shafts, etc. They are widely used in packaging machines, printing machines, die-cutting machines, laminating machines, slitting machines, blown film machines, coating machines and other machines that require winding and unwinding.
After compressed air is inflated, the key strips on the surface of the shaft can protrude (increasing the shaft diameter), and after deflation, the key strips on the surface quickly retract (restoring the shaft diameter), which is used to tighten the cylinder core.
The air shaft is a specially designed winding and unwinding shaft, which can protrude on the surface after high-pressure inflation. The shaft that quickly retracts on the surface after deflation is called the air shaft. Its names are diverse, also known as pneumatic shaft, expansion shaft, expansion shaft, expansion roller, inflation shaft, pressure shaft, expansion roller, etc.
SUN HONG can support non-standard customization of 1-24 inches, with materials including aluminum, steel, and stainless steel to choose from, and supports sampling based on drawing.
Air Shaft with Leaves
The expansion part of the Flat noodles type air expansion shaft (air expansion shaft) is a plate, which can be used for machines with high winding precision or articles with light winding.
Air Shaft with Expanding Keys
The expansion part of the key strip inflatable shaft (inflatable shaft) is the key strip, which can be used for mechanical winding of heavy load-bearing items.
Air Shaft with Expanding Strips
The expansion part of the strip type inflation shaft (inflation shaft) is a full-length key strip, which has the characteristics of high precision, high load-bearing capacity, and light weight.
Advantage of Sun Hong Air Shaft
1. The inflation time is short: the separation and placement of the air shaft and the paper tube can be completed in just 3 seconds, no need to disassemble any parts on the end of the shaft, which can tightly engage the paper tube. 2. Easy installation and placement:With only the action of inflation and deflation, the paper tube can be moved and fixed at any position on the shaft surface. 3. Large ring width: smooth rotation with low friction, convenient for loading and unloading. 4. Large bearing weight: The size of the shaft diameter can be customized according to the actual needs of customers, and high stress steel can be selected to increase the bearing weight of the shaft. 5. High usage accuracy: The shaft body is made of alloy steel, with strong deformation resistance and small circumferential runout. 6. High Economic efficiency:the shaft is designed for special functions, all kinds of paper tubes with different thicknesses and widths can be used. 7. Simple maintenance and long service life: As a single component, the air shaft has corresponding fixed specifications for each part in its internal structure, and can be interchangeable and universal, reducing maintenance costs
