China customized friction element for prinitng machine

China  customized friction element for prinitng machine

 1.Description

The air shaft introducing foreign advanced production equipment and fabrication technology, using imported balloon, the shaft is casting by aluminum alloy, shaft body plating chromium, accurate assembly,convenient to use and long operating life. When using, match with our company's professional configuration of the aerate gun filling gas for the nozzle jet, to make the shaft of off-axle appearance uniform expansion, thereby lock nitrogentreated barrel, when unloading, press on deflated mouth to deflated, then nitrogen-treated barrel can be unloaded.

2.Application

A.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.
B.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.

 3.Specification

 To meet our customers’ special requirements, according to the drawing, we can make steel shaft head with different sizes.

4.Our air shaft friction element Feature

A.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.

B.The body of the differential shaft ring is made from steel,stainless steel or aluminum. The friction plate can be made from polyurethane, polyethylene, or rubber  to realize max tension required

C.Friction Air shaft in practical applications, it has advantages of convenient operation, quick, without damage rolls etc.

5.Working principle

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.
