Introduction And Use Of The Key Type Air Expansion Shaft

The inflation shaft is a special type of winding and unwinding, that is, the shaft that can be raised by the high pressure inflation surface (the key strip). The shaft that is quickly retracted after the deflation is called the inflation. axis.

The name of the inflation shaft is diversified. It is also called the air pressure shaft, the expansion shaft, the inflation shaft, the air expansion roller, the inflation shaft, the pressure shaft, the air expansion roller, etc. Although there are many names, the working principle is the same. The inflation shaft and the inflation The sleeve is extremely convenient and quick to use. It only needs to be supplied with air source. The air pressure is controlled within the range of 6-8kg/cm2. When the external components (such as a round paper tube) need to be locked, as long as the air gun is facing the inflation shaft. The air nozzle can be inflated, and the key bar will protrude against the external parts (such as a circular paper tube). When the paper is unloaded, press the sliding air core on the air nozzle to release the air. Will return to the original appearance, external components (such as a circular paper tube) can be taken out professional production of inflatable shaft, maintenance of the inflatable shaft,
       1. Plate type air expansion shaft:

      Name: Also known as sheet air expansion shaft. Slat inflation shaft. Six-piece air expansion shaft. Tile air expansion shaft, etc. But the working principle is the same, the user must specify the type of inflation shaft when ordering the inflation shaft. Dimensions. Mark the tolerance level and order quantity of the important dimensions on the shaft. If there is a request for the special, please specify otherwise.

      Features: The key type air-expansion shaft adopts aluminum alloy tile, flexible expansion and contraction, high-quality rubber liner and fast inflation exhaust nozzle, good sealing effect, long service life of key type air expansion shaft, detachable shaft head, maintenance Convenient, after inflation, the expansion part is the plate, usually the height of the expansion can reach 4MM to 5MM (such as the expansion of the 3 inch diameter before the expansion of 74MM-75MM diameter can reach 78MM-79MM), special expansion height, additional requirements, 3 Inch plate type inflatable shaft, usually using a coiled tube inner diameter of 76MM.

Key-type air-expansion shaft is applicable: the key type air-expansion shaft expands from the whole plate, the fulcrum is evenly distributed, and the force is uniform. It can be applied to machines with high precision of winding or lighter items, such as: Electronic materials / battery materials / foamed cotton / plush / paper / non-woven / etc., suitable for coating machines, slitting, printing, rewinding, composite, paper, bag, plastic and other related machinery Retractable reel, especially for the occasion of high roundness requirements for paper tubes or surface retractable rolls, can effectively improve the work efficiency and product quality.

3 inch flange fixed plate type air shaft

       One end is flange fixed, one end is inflated, the surface is brown, suitable for trademark printing machine, die cutting machine, etc. The coaxiality and runout are within 0. 10MM, and the length and color are determined according to customer needs.

       Name: 3-inch plate type inflatable shaft

       Single axis fixed. Inflated at one end, the surface is brown or golden yellow, suitable for printing machinery, die-cutting machinery factory, die-cutting machinery, electronic material rewinding and unwinding machinery, etc., coaxiality beating can be carried within 0. 1MM Heavy items and materials, according to customer needs, length and color.
