2、 Main component description

1. Uncoiler machine

The uncoiler unfolds the rolled strip for slitting by the slitting machine. The drum is a cantilever manual expansion and contraction four pyramid structure, and the unwinding machine moves along the track to adjust its position to achieve the alignment of the strip feeding. The track adopts HIWIN linear guide pair and magnetic powder brake.

Nominal diameter of the drum: φ 100 mm (drum body diameter of φ 100 mm)

2. Longitudinal cutting machine

The longitudinal cutting inlet end is equipped with a guide device, and the side guide plate can be adjusted in the left and right, front and rear directions. The guide device can also be adjusted up and down according to the grinding of the cutting tool. The guide device track adopts HIWIN linear guide pairs, which are convenient to operate and ensure the accuracy of the movement position.

The lower cutter shaft is fixed, and the upper cutter shaft is lifted by self-locking mechanism and left and right synchronous lifting mechanism. There is clearance elimination link, and the pointer shows the adjustment amount. The movable memorial archway can be moved out, which is convenient for tool installation and replacement. The moving out track uses HIWIN linear guide pairs.

The longitudinal cutting power adopts an AC motor, which is transmitted to the upper and lower cutter shafts through a synchronous toothed belt and gear pair via a reducer.

Shear force: 4KW

3. Coiling device

The winding adopts a dual support structure, and the winding tension can be adjusted by adjusting the controller of the magnetic powder clutch of the winding device.

Nominal diameter of drum: φ 35 mm

4. Electric control system

The electronic control system adopts variable frequency speed regulation, and the operation console is installed on the longitudinal shear machine.
