1: Introduction to the air swelling axis:

The gas expansion shaft and sleeve are a special winding and discharge shaft. They are shafts that can protrude and quickly retract after high-pressure inflation. It is also called an air pressure

shaft, an expansion shaft, an inflation roller, an inflation shaft, a pressure shaft, an inflation roller, etc. Although there are many names, the working principle is the same. The air-scaling shaft

and sleeve are extremely convenient when using it. Just prepare an air source and the air gun can inflate the air nozzle on the air-scaling shaft to complete the inflation operation. Press the

sliding air core on the air nozzle with your hand to deflate.

2: Characteristics of the gas surge shaft:

1. The inflation operation time is short, and the separation and placement of the air expansion shaft and the paper tube can be completed in just 3 seconds. It does not require any parts on

both sides of the shaft end, and it can also be closely connected to the paper tube.

2. Simple placement of paper tubes: inflate and deflate the paper tubes to move and fix any position on the shaft.

3. Large load bearing weight: The size and length of the shaft diameter can be determined according to the actual needs of the customer, and high-hard steel can be used to increase the load

bearing capacity.

4. High economic efficiency: The shaft is designed with special functions and is used for all kinds of paper tubes that are thick, thin, wide and narrow.

5. Simple maintenance and long service time: the air-scaling shaft is a single part, and each part in its structure has fixed specifications and can be used interchangeably to make it easy to

maintain.

Three: The specifications for the front and rear dimensions of the key bar gas expansion shaft are as follows:

Fourth: The specifications for the front and rear dimensions of the slat-type inflation shaft are as follows:

5: Uses of gas surge shafts: The gas surge shafts are widely used. Any machines that contain coiling, slitting, and slitting can be used as gas surge shafts, even including the light metal industry. For example, the air-scaling shaft is mainly suitable for printing equipment: plate machine, flexo printing machine, gravure plate machine, trademark printing machine, etc.; other machinery include: coating machine, leather machine, shaping machine, embossing machine, die cutting machine, rewinding machine, paper barrel machine, bag making machine, lamination machine, film blowing machine, foaming machine, film coating machine, pressing and drop machine, paper making machine, non-woven fabric machine, fabric inspection machine, hot stamping machine, battery equipment and other related machinery supporting equipment.

1. The key type air swelling shaft is also known as the five-claw type air swelling shaft. It is uniformly used in the five-part airbag span design, and has good balance.

2. The main material can be made of steel or aluminum according to customer requirements. The airbag is made of white airbags imported from Italy, with a longer service life and better

fatigue resistance. High-quality rubber long keys are used in the key area.

3. Compared with the general key strip and slat type air-scaling shafts, the tightening force is better and more uniform, and the load is heavier. It is especially suitable for high-speed slitting

machines, lamination machines, and feeding machines.

4. Easy to repair, you can repair it yourself
