The structure introduction of uncoiler in the slitting line

Jime

The uncoiler is a welded box structure, and the frequency conversion speed regulating motor drives the drum shaft to provide the main power for the uncoiler after decelerating through the gearbox. The reel of the uncoiler is a hollow shaft, which is supported on the gearbox body by two bearings. The driving spur gear is installed between the bearings. The gearbox adopts forced lubrication and is equipped with two constant speed motors for closed loop oil lubrication system. The mandrel is cantilever structure, and the front end is supported by the external support bearing when unwinding, so as to maintain the rigidity and stability of the unwinding machine.

The mandrel of the uncoiler is connected with four fan plates through four inclined dovetail grooves on the end face. Each fan plate is prevented from moving in the axial direction by a radial slider at its end, but can expand and contract in the radial direction. The rotating cylinder is connected to the tail end of the drum shaft, and the piston rod of the cylinder drives the front quadrilateral axis to slide axially through the pull rod in the center of the drum shaft, thus driving the radial expansion and contraction of the fan plate. The nominal diameter of the reel can be increased by adding four fan plates. The frame of the uncoiler can move on the guide rail of the uncoiler base and is driven by the hydraulic cylinder to realize the central position control. In order to enhance the stability of the drum, a supporting arm device is designed at the head of the drum. When there is a steel coil on the drum, the cylinder drives the support arm to support the head of the drum. The support arm is usually retracted without affecting the rewinding of the steel coil.
