It is also called sheet gas expansion shaft, strip gas expansion shaft, tile type gas expansion shaft, etc., but the working principle is the same. When customizing the gas expansion shaft, users must specify the type and overall dimensions of the gas expansion shaft, and mark the tolerance of important dimensions on the shaft. Special requirements shall be noted separately

Characteristics of lath type inflatable shaft

The slat type air expansion shaft adopts aluminum alloy tiles, which are flexible in expansion and contraction. It is equipped with excellent rubber liner and quick air filling and exhaust nozzle, which has good sealing effect, long service life, removable shaft head and convenient maintenance. After inflation, the expansion part is a plate, and the expansion height can generally reach 4-5 mm (for example, the diameter of 3 inches before expansion is 74 to 75 mm, and the diameter after expansion can reach 78 to 79 mm). The special expansion height is otherwise required. The inner diameter of the 3 inch plate type air expansion shaft is usually 76 mm.

Suitable for lath type air expansion shaft

The lath type air expansion shaft expands the whole board, the fulcrums are evenly distributed, and the force is uniform. It can be applied to machines with high precision or articles with light winding, such as electronic materials, battery materials, foam cotton, plush, paper, non-woven fabrics, etc. It is applicable to the reels of coating, slitting, printing, rewinding, laminating, papermaking, bag making, plastic and other related machinery, especially for the occasions where there is a high requirement for the roundness of paper tubes or the surface reels and reels are used, which can effectively improve the work efficiency and product quality.
