Problems solved by technology

Such as: the air shaft is mainly suitable for printing equipment: drying board machine, flexo printing machine, gravure machine, trademark printing machine, etc.; other machines include: coating machine, leather machine, setting machine, embossing machine, slitting machine machine, die-cutting machine, rewinding machine, paper tube machine, bag making machine, laminating machine, laminating machine, film blowing machine, foaming machine, laminating machine, embossing machine, paper machine, non-woven machine, Cloth inspection machine, bronzing machine, battery equipment and other related mechanical equipment, however, the existing airbag air shaft relies on a single airbag (expansion tube) to support the raised part. When the reel is large, it is prone to uneven swelling, which will affect the accuracy of winding, unwinding, slitting and other processes. Therefore, it is necessary to propose a multi-airbag air-inflatable shaft

Abstract

The invention discloses a multi-airbag inflatable shaft. The shaft comprises a hollow shaft rod, a limiting shaft sleeve, a sealing baffle plate, a connecting shaft sleeve, a guide shaft sleeve, a topplate, an airbag and a top sheet. Compared with the prior art, the inflatable shaft of the invention has advantages that the structure is simple and a design is reasonable; a reel with large mass canbe effectively supported; and heights of surface embossments are ensured to be uniform and consistent. In addition, the inflatable shaft has a function of adjusting the heights of the embossments, the heights of the embossments can be adjusted according to actual needs, and applicability is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of air shafts, in particular to a multi-airbag air shaft. 【Background technique】 [0002] The inflatable shaft is a special winding and unwinding shaft, the surface part expands after high-pressure inflation, and the surface part retracts rapidly after deflation. The air shaft is very convenient and quick to use. The user only needs to prepare the air source, and the air pressure is controlled within the range of 6-8kg. When the reel core needs to be locked, just inflate the air gun to the air nozzle on the air shaft , When it is necessary to loosen the reel core and unload, press the sliding air core on the air nozzle with your hand to deflate. [0003] Because it is easy to use, it has a wide range of uses. All machines with winding, unwinding and slitting are applicable to the air shaft, even including the light metal industry. Such as: the air shaft is mainly suitable for printing equipment: drying b...
