tension controller for printing machine,bag making machine and other machines

Control method: It can select the feedback, winding taper and unwinding taper tension. The default is feedback tension which is according to the setting tension and measure tension adjust to output proportion correspondingly and realize to control the tension permanence automatically totally. When you select the winding taper of unwinding taper to control that according to the Hall switch outside repeat to pick

up the pulse amount which made by the materials pass the guide rod reaches to the set pulse amount, then the tension controller adjusts the output proportion and the reel diameter of the reel canister changes change the taper tension fogging, this method is simple and easily install that is suit for the scene of not high request to be constant tension control.
