Inflatable Shaft Related Knowledge

concept:

Inflatable shaft: It is a special type of winding and unwinding, that is, the shaft that can be raised by the surface after high pressure inflation. The shaft that is quickly retracted after the deflation is called the gas. Expansion axis. Its name is diversified, also known as pneumatic shaft, expansion shaft, inflation shaft, air expansion roller, inflation shaft, pressure shaft, air expansion roller and so on.

Principle: Although the inflation shaft is called more, the working principle is the same. The air expansion shaft and the air expansion sleeve are extremely convenient and quick to use. Only the self-prepared air source is required. 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 The air nozzle on the inflation shaft can be inflated, and the key bar will protrude against the external components (such as a circular paper tube). When the paper is unloaded, press the sliding air core on the air nozzle. That is, deflation, the key bar will return to its original appearance, and external components (such as a circular paper tube) can be taken out.

Classification: Inflatable shaft is divided into expansion type air expansion shaft (metal/non-metal), vane type air expansion shaft, expansion button type air expansion shaft, aluminum alloy air expansion shaft, differential air expansion shaft, spiral external type Inflatable shaft, large expansion inflatable shaft, pneumatic nail shaft, etc.

Features:

1. The inflating operation time is short, and the separation and placement of the inflation shaft and the paper tube can complete the inflation and deflation in only 3 seconds, and it is not necessary to separate any parts on the shaft end side to be tightly engaged with the paper tube.

2, paper tube placement is simple: in the action of inflation and deflation, can move and fix the paper tube at any position on the shaft surface.

3, the carrying weight is large: according to the actual needs of customers, to determine the size of the shaft diameter, and the use of high-hard steel, so that its load bearing increased.

4. High economic efficiency: The design of the shaft is special, and it can be applied to all kinds of paper tubes with thick, thin, wide and narrow.

5, simple maintenance, long use time: the inflatable shaft is a single part, each part of the structure has a fixed specification, can be used interchangeably, making it easy to maintain.

Specifications:

There are a variety of, including 1 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, 6 inch, 8 inch, 10 inch, 12 inch, etc., according to demand can be processed to produce different specifications of the expansion shaft.

Structural features:

The main body of the shaft is made of high-quality steel pipe, and the surface is chrome-plated; the aluminum convex key is flexible; the high-quality rubber liner and the fast filling and exhausting nozzle are provided, the sealing effect is good, the service life is long; the detachable shaft head is convenient for maintenance.

Uses:

The air-expansion shaft has a wide range of applications. For machines with winding, unwinding and slitting, the air-expansion shaft can be applied, even in the light metal industry. Such as: the inflation shaft is mainly suitable for printing equipment: drying machine, flexo printing machine, gravure machine, trademark printing machine, etc.; other machinery: coating machine, leather machine, setting machine, embossing machine, slitting 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, The use of the inspection machine, bronzing machine, battery equipment and other related machinery retractable reels can effectively improve the efficiency.
