Slitter

The utility model relates to a longitudinal splitting machine, which is used for winding-drum-shaped materials, such as paper, films, etc. A position of a relevant roller shaft is reselected and an arc-shaped roller is improved, and a no shaft type uncoiling mechanism and a braking blocking disc are worked out. Thus the presetting of tension can be kept constant and can be automatically returned and reduced. An ac frequency conversion servo motor is used as power, which not only is convenient for adjustment and loading and unloading, but also high-speed slitting can be steady and reliable. An FIFE deviation rectifying mechanism is used, which enables the position of a detection point to be preferred out. The uncoiling mechanism is arranged on a guide rail which can be laterally moved to form a regulating link of the longitudinal splitting machine. The best fit of the response of deviation rectifying and the slitting speed is achieved, and the high-precision slitting of a wide adaptability of base materials is achieved.
