The air shaft rubber tube is divided into flat rubber tube and round rubber tube, and the specifications of the flat tubes are divided into three specifications with a width of 15*1.2mm, 20*1.5mm and 25*1.5mm. Generally used for friction air shaft more; The round air shaft rubber tube has many specifications, 30*20mm, 35*25mm, 38*28mm, 40*30mm, 45*35mm, 50*40mm and so on.
The thickness of each side is basically 5mm. Customers choosing air shaft rubber tube also need to choose different tubes according to different suppliers.
Rubber tubes for expanding air shafts, often referred to as air shaft expansion tubes or simply expansion tubes, are flexible rubber or silicone components used in the paper, film, and converting industries. These tubes are typically placed around the core of an air shaft (also known as an air mandrel or bladder shaft) and are integral to the operation of the equipment used for winding and unwinding rolls of material.
Here’s how they work:
1. Mounting: The rubber tube is mounted around the metal core of an air shaft. The air shaft is a cylindrical device with a series of radial slots or holes that allow for the passage of air.
2. Inflation: When air pressure is applied to the inside of the rubber tube, it expands. As the tube expands, it presses against the inside wall of the material roll (such as paper or plastic film), gripping it tightly.
3. Securing the Roll: The expansion of the rubber tube secures the roll of material to the air shaft, allowing for efficient and controlled winding or unwinding during the manufacturing process.
4. Adjustability: The air pressure within the tube can be adjusted to control the tension on the material, making it suitable for a wide range of material thicknesses and tensions.
5. Release: When the air pressure is released, the rubber tube deflates, and the roll can be easily removed from the air shaft.
Key features and benefits of rubber tubes for expanding air shafts include:
Variable Diameter: They can accommodate rolls of various diameters.
Easy Mounting and Dismounting: They facilitate quick and easy changeover between rolls.
Tension Control: Precise control over the winding tension helps maintain product quality.
Durable Material: The tubes are made from robust materials that can withstand the mechanical stresses of the converting process.
Customization: They can be custom-made to fit specific air shaft designs and application requirements.
Rubber tubes for expanding air shafts are essential components in the efficient operation of web handling machinery, particularly in applications involving the handling of sensitive or delicate materials.
