Jinan Jinchangtai Industry And Trade Co., Ltd
Air Inflatable shafts have a wide range of uses. Any machine that has rewinding, unwinding and slitting can be used for inflatable shafts, even the light metal industry. For example, the air-expanding shaft is mainly suitable for printing equipment: platen printing machine, flexo printing machine, gravure printing machine, trademark printing machine, etc .; other machines are: coating machine, leather machine, setting machine, embossing machine, slitting machine Machine, die cutting machine, rewinding machine, paper tube machine, bag making machine, laminating machine, laminating machine, film blowing machine, foaming machine, laminating machine, embossing machine, paper machine, non-woven machine, It is used for cloth inspection machine, hot stamping machine, battery equipment and other related machinery.
Steel and aluminum lug type air shaft for papaer making machine
1. The type of air shaft
1. According to the structure
1) key type air shaft
2) lath type air shaft
2. According to the diameter
We have the following normal type but other dimensions can be customized.
1.The connection of spindle head and steel tube is interference fit
We are using a high power press machine which can produce 80T thrust to realize all the combination of spindle head and steel tube.
While other suppliers knock the spind head into the steel tube with a big hammer, no quality and accuracy.
2. Adopting hi-precision cold-drawn steel tube as the shaft body
We adopt hi-precision cold-drawn steel tube as the shaft body.The thickness of this kind of tube is uniform so when the rubber balloon inside is inflated,
all key strips will stick out at same height and good material can help keep a better dynamic balance.
3. Adopting whole long key bar and pagoda springs for key type air shafts
For the key strip,we adopt a whole piece of aluminum plate to make it. And it can form a good protective ring around the air bladder.
We adopt the pagoda springs to support the air bladder which can bear 300000 times.
4.The connection between our air bladder and shaft head have good sealing performance and very stable.
We use special equipment to connect the air bladder and the shaft head and then lock the outside by iron ring,which will realize tight seal.While,
many other suppliers fasten both ends by iron wire ,this operation is easy to leak, has badly sealing performance.
5. Quality control
We have the quality control system during the whole production from the very beginning to the end and our principle is to make sure each shaft is qualified.
