Air Shaft for Paper Making Machine

Product IntroductionThe 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.Product Working principleThe air shaft is powered by high-pressure gas and controls the surface protrusion of the shaft through inflation and deflation, achieving surface expansion and tension control of the shaft. The air shaft is used in specially designed winding equipment to facilitate loading and unloading, save time, and improve work efficiency. Although there are many names for the air shaft, its working principle is the same.product Feature1. 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 costsProduct UsageAir shaft has a wide range of applications. Any machine with winding, unwinding and slitting can be used for air shaft, even in Light metal industry. The air shaft is mainly suitable for printing equipment such as  flexographic printing machines, concave printing machines, trademark printing machines, etc; Other machinery includes: paper making machines, coating machines, leather machines, shaping machines, embossing machines, slitting machines, die-cutting machines, rewinding machines, embossing machines, and other related machinery supporting their use.Product detailed parameterRoll Core Standard TypeAxis outer diameter without inflatableExpossed diameter after inflatable1.5 inchØ36mmØ40 - Ø42mm2 inchØ49mmØ53 - Ø55mm3 inchØ74mmØ79 - Ø82mm4 inchØ100mmØ104 - Ø106mm4.5 inchØ120mmØ124 - Ø126mm6 inchØ150mmØ155 - Ø158mm8 inchØ200 mmØ205 - Ø208mmProduct Leak Reason 1. The rubber pipe is ruptured, and the rubber pipe may have quality problems itself. You need to remove the shaft head and replace it with a rubber tube.2. There is a gap between the sealing ring. This situation needs to be sealed in the sealing glue3. Loose the pressure circle, just tighten the pressure ring. Pay attention to whether to observe whether there is a loose at any time4. The inflatable mouth is leaked, then replace it again and then install it.Customers are welcome to come to consult, sun hong will provide you with a series of solutions according to your specifications and needs, if you have any questions during use, we will reply within 24 hours.  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
