The previous slitting machine

Slitting machine is a wide paper or film will be cut into many narrow the mechanical equipment used in paper-making machinery and printing and packaging machinery. Slitter traditional control scheme is to use a large-volume motor to drive the retractable shaft, the retractable reel plus a magnetic clutch, by adjusting the magnetic clutch to control the current generated by its resistance to control the surface tension. Let's us see the previous slitting machine.

? Magnetic particle clutch before slitting machine speed can not be high, because the run time could easily lead to high-speed magnetic friction, high temperature, shorten its life, Serious will get stuck, the machine works blocked, to the production very serious consequences. Serious impact on productivity.
