The differential air shaft consists of a plurality of slip rings, which can overcome the problem of unwinding and material damage. The slippage rings are controlled to slip at a certain slip torque (torque), and the amount of slip exactly compensate for the difference in speed, thus it can control the tension of each roll precisely, which ensure the winding quality.
Slip differential air shaft for slitting machine
Differential shaft applied mainly to wind shaft, or unwind shaft in special occasions.
The body is made from chrome-plate steel or hard anodized aluminum. The friction plate can be made from polyurethane, polyethylene, or rubber to max tension required.
To meet our customers’ special requirements, according to the drawing, we can make steel shaft head with different sizes.
1).Widely uesd for all kinds of Machines It is used for slitting machine,coating machine,cutting machine,printing machine,compounding machine,paper making machine,bag makeing machine, embossing machine and so on .It can greatly improve the working efficiency and the quality of products. 2).It also used for Material Differential air shaft has been widely used in plastic film including electronic, capacitor, battery film, plastic wrap, packaging, composite film, metal foil such as copper foil and aluminum foil, paper and pvc sheet.
c.Air shaft friction Feature
Our differential air shaft with slipping friction can ensure the highest winding quality, and by keeping proper tension on all rolls throughout the winding operation, materials will not show any problem.
It works under the theory that friction rings slip constantly in center of air shaft, and to keep same tension, some rings slip faster than others. So tension of each roll can be controlled accurately, and permanent tension can also be gained to guarantee the quality of roll.
According to different roll diameters, to control air pressure of air bag and to guarantee tension, a constant air pressure source kept by rotary joint is required.
