Strip Type Air Expanding Shaft

Description1inch air shafts are used in the producing processes for fitting into a core onto which materials such as fabric, nonwoven and plastics are winded. An Expanding Shaft is designed so that, on fitting into a core, it can be easily expanded, thereby achieving a quick and firm attachment, it may also be rapidly deflated to facility easy withdrawal of the shaft after winding of product is complete.Specially recommended surface multi bladder inflation shaft:The traditional air shaft has only a single central airbag, and the expansion force applied to each key is not uniform, and the concentricity is difficult to ensure, and the maintenance of the bladder is difficult after the damage, which is very time consuming.Technique parameter ModelInner Diameter of Paper TubeShaft Diameter Before ExpandingShaft Diameter After Expanding1″ ShaftΦ25.4mmΦ24.5mmΦ27.5mm-Φ28mm1.5″ ShaftΦ38mmΦ37mmΦ41mm2″ ShaftΦ50mmΦ49mmΦ53mm3″ ShaftΦ76.2mmΦ74mm-Φ74.5mmΦ82mm4″ ShaftΦ102mmΦ100mmΦ108mm6″ ShaftΦ152.4mmΦ150mmΦ158mm8″ ShaftΦ203.2mmΦ200mmΦ210mm10″ ShaftΦ254mmΦ250mmΦ260mm12″ ShaftΦ304.8mmΦ300mmΦ312mmThe surface continuous long-key inflatable shaft has many advantages:1. The key strips and airbags are evenly arranged on the surface of the shaft body. Unscrew the two ends of the convex key and press the rubber key strip to remove the airbag easily. The maintenance process is less than ten minutes. The disassembly process does not reduce the flatness and balance of the pneumatic shaft.2. Since the expansion parts are evenly distributed on the shaft diameter surface, the flatness and balance of the whole shaft are good, and the concentricity is high, which is especially suitable for high-speed operation of the machine;3. Multiple sets of airbags share the internal intake valve of the air-expansion shaft, so they are not eccentric and ensure high torque characteristics.4. The key strip is made of rubber and steel sheet. The airbag is installed under the key strip. When the steel is swollen and contracted, the steel sheet acts to protect the airbag. The height of each key strip is consistent and stops at the limit device, so it will not damage the inner wall of the paper tube. Where the torque requirements are particularly high, the key strips must be made of steel, aluminum or hard plastic.This new scientific air shaft product, to meet the needs of higher performance, will become the mainstream of the future market.5, Scope of application: Used in the occasion of high requirements for the uniformity of the end face of the rewinding and unwinding, high-speed operation.ApplicationAir shaft prcocessing flowPackaging About usDongGuan HongJun Packaging Technology Co., Ltd. is committed to intelligent correction system, automatic tensioning system, sliding shaft, pneumatic shaft, pneumatic sleeve, magnetic powder clutch brake, electromagnetic pneumatic clutch brake, fast safety chuck, aluminum guide roller, mirror roller and The research and development, production, sales and after-sales service of other products provide various tension and correction control solutions for the field of coil equipment.Order DetailsItem Name3inch Multi Bladder Type Air Expanding ShaftMOQ(Minimum Order Quantity)1PcLead time13-18 days after receiving the depositCalculated Weight13kg/MeterPackageWooden Tube/Wooden BoxPrice TermEXW,FOB, CIF, etcPayment termTT,L/C,Western UnionCountry of OriginChina/* 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
