3. Description of the whole machine line

        ZJX-4*1600mm steel coil slitting line is used for slitting the carbon plate to prepare for the next process.

a. Hydraulic entry coil car

    The car can move levelly and vertically, which is convenient for putting the steel coils into the de-coiler

    It is driven vertically by hydraulic cylinder with four guide pillars

    The level movement is driven by cycloid motor

b. Hydraulic un-coiler

    Supporting steel rolls and uncoiling

    It can expand and shrink with hydraulic oil cylinder and fit with the inner hole of the steel coils and is equipped with supporting stand

    Moment motor drives the coils running and the motor can run right and left to prevent the coils running by inertia

c. Press and pinch and feed device

    It is good for
