Use High-quality Materials For Manufacturing Inflatable Shafts

The common inflatable shaft is composed of an inflatable shaft and a long-span inflatable shoe. The torque of the expansion shoe is adjusted by the inflation pressure. Because the structure of the expansion shoe is a long shaft through the shaft, there is no section, so there is no slip function. There is no corresponding slip action for the tension change due to material changes when cutting multiple strips, which easily results in uneven winding, broken strips, loose coiling, and unrolling, which causes material loss. Winding speed is low. Adjusting the air pressure should be stopped to affect the work efficiency. The unified axis cannot take up large and small rolls at the same time.

Slitting machine is one of the main independent equipments of mechanical enterprises. The good or bad of its function directly reflects the level of product and production efficiency.

The function of the winding shaft on this machine determines the performance of the slitter. At present, most of the slitter rewinding shafts used by China's machinery enterprises are mechanical slip shafts and ordinary inflatable shafts. Slip differential inflatable shafts are rarely used.

The mechanical slip shaft is composed of optical shaft, slip sleeve and compression spring adjusting mechanism. The working principle is to adjust the torque force of each slip sleeve on the shaft by the pressing force of the pressing spring adjusting mechanism at both ends of the shaft. Because its structure is mechanically transmitting pressure from both ends of the shaft, the pressure on each slip sleeve is not even, so the torque of each slip sleeve cannot be fully adjusted according to the change in tension required for the cutting material change. The relative sliding is not good, easily causing uneven rewinding, broken strips, loose coiling, and unrolling, resulting in material loss. Winding speed is low. When adjusting the pressure, the machine must be stopped and adjusted, which affects the work efficiency.

The inflatable sleeve of the inflatable shaft belongs to a keyless coupling device. It works by the principle of high-strength tension bolts. It generates a huge holding force between its inner ring and the shaft and between its outer ring and the hub. Keyless connection of the machine to the shaft. When bearing the load, the torque, axial force or the combined load of the two is transmitted by the combined pressure of the expansion sleeve, the machine and the shaft and the associated frictional force. Inflatable sleeves can also be called keyless bearings and tight coupling sleeves. If the inflatable sleeve does not work properly, it will be prone to unwinding, broken bars, loose coiling or unrewinding during rewinding, so the inflatable sleeve of the inflatable shaft plays an important role in the production process. Role. Inflatable sleeves are made of high-quality materials, which effectively improves its performance and use, and increases the use time of inflatable sleeves, reducing the problem that is prone to problems during work.
