Name: It is also called plate-expanding shaft, slat air-expanding shaft, tile-type air-expanding shaft, etc. However, the working principle is the same. When the user specifies the air-swelling shaft, it must specify the type of air-swelling shaft, dimensions, and the shaft Tolerances on important dimensions, special requirements, otherwise noted.
Features: The use of aluminum alloy tiles, flexible expansion and contraction, the configuration of high-quality rubber liner and fast filling and exhausting gas nozzle, good sealing effect, long service life, dimension removable head, easy maintenance. After inflation, the expansion part is a plate, usually bulging height up to 4-5 mm (if the expansion of the 3 inch diameter of 74 to 75 mm, diameter after expansion of up to 78 to 79 mm), special expansion height, another request , 3 inch plate expansion shaft, usually with a coil diameter of 76 mm.
Applicable: The plate expansion shaft starts from the entire plate, the support point is even and the force is even. It can be applied to the machinery with higher winding precision or lighter articles such as electronic materials, battery materials, etc. Foaming cotton, plush, paper products, non-woven fabrics and so on. Applicable to rewinding reels for coating, slitting, printing, rewinding, compounding, papermaking, bag making, plastics, and other related machines, especially suitable for applications where the paper tube has a high degree of roundness or where surface rewinding is required. Can effectively improve ergonomics and product quality.
