Inflatable shafts are widely used in many modern industries such as printing, coating, and lithium battery diaphragm production. Understanding their technical requirements is crucial for related foreign trade businesses.
In terms of design structure, the key components of inflatable shafts include shafts, air bags, air nozzles, etc., and each component needs to be precisely matched. For example, the shaft should ensure a reasonable shaft diameter design with a large diameter in the middle and small diameters at both ends, as well as chamfering of the shaft ends and journals to improve rigidity during load bearing and reduce stress concentration.
The choice of materials directly affects the performance of inflatable shafts. The use of high-strength steel is an important means to improve load-bearing capacity and durability, while surface treatment, heat treatment and other processes are used to enhance the wear resistance and corrosion resistance of the material.
Operation technology is also an important consideration. The separate placement of the inflation nozzle and the paper tube can improve operating efficiency, and the standardized design facilitates component maintenance and replacement. Optimizing the deflation process and shortening the deflation time can achieve uniform pressure distribution and avoid local overload.
In terms of performance, it should have good load-bearing capacity and rigidity to ensure that it will not be deformed or damaged under heavy objects; it should be easy to operate, and the paper tube or roll should be quickly locked and released by simple inflation and deflation; it should also be economical and applicable, adaptable to rolls of different sizes and consider cost-effectiveness.
In actual use, problems such as air leakage, uneven load, and inconvenient disassembly and assembly are more common. It is necessary to check the sealing parts regularly, and use high-quality sealing materials and advanced technologies to solve the air leakage problem. Special processes are used to solve uneven load, and modular and standardized parts are used in the design to improve the convenience of disassembly and assembly. These technical requirements ensure that the inflatable shaft can operate stably and reliably in complex industrial environments, helping related products to be competitive in the international market.
