GK820T AC Motor Drive for Winding and Rewinding
Film Slitter consists of by rewinding mechanism, slitting mechanism, winding mechanism, as well as various functional roller and deviation rectification control and detection device. Its working principle is as follows: the film material out from the rewinding mechanism, goes through the nip roll, deviation rectification system and enters into the slitting mechanism. After the raw material is cut, standard film roll can be winded by winding mechanism.
Features of GK820T on the application of film slitter
GK820T dedicated drive controls the winding motor, with functions below:
The drive is self-equipped with the encoder interface; no additional card needed, which saves cost;
In the tension-free sensor mode, rolling diameter calculation of winding, and constant tension control can be achieved;
Users can set the taper tension control curve by themselves;
With sliding and high-speed sliding friction compensation;
With mechanical inertia compensation coefficient;
Since GK820T drive has accurate tension control under different rolling diameters, it can completely overcome wrinkles due to improper tension in film production, which greatly improves the quality of the product.
GK820 is the high-performance series which covers an entire range of applications, particularly for demanding ones that require precise speed control, torque control and fast response, etc.
