6) form of damping: belt tensioning machine

Usage and theory of the belt tensioning machine:

1) it is installed before recoiler in the whole line and which is composed of different materials and special belts with the difference in the coefficient of friction

   2)The friction resistance is occurred by the inner face of the belt and the steel-made slidings which functions the sheet anti-tension and make the recoiler more tight and not cause the scratch on the surface of the sheet

  3) the special belt is separated into many slits and can be extended differently and singly by the idler and make the the strength of strips reeled averagely.The tensioning strength is produced by adjusting the hydraulics pressed down,therefore anti-tension can be adjusted according to the different material or material thickness .

  Advantage of the belt tensioning machine

1) It can make the coil reel tidy and tight and less fault in ply

2) It can avoid the scratch on the surface of the sheet while the sheet and belt moves synchronously .

3) The special circle belt ,installed directly on the idler with cycled cooling units inside and it can keep cooling status

4) It is easy to adjust the strength of the belt manually according to different thickness

5)The support bracket of recoiling shaft: steel structural component, hydraulic cylinder Φ80×350mm

6)Strips-separating shaft: Φ95×1300mm

7)Separating discs: Φ180×3mm, 65Mn quenching treatment

8)Pressing-down the separating shaft: hydraulic Φ80×300mm, strength adjustable

9)Recoiling power: DC 75KW motor

10)DC motor control: Eurotherm 590 controller

11)Recoiling speed: 0-- 80m/min adjustable

12)Max recoiled coil weight:20000kg
