4) With servo motor unwinding device;
5) Equipped with manual tape receiving platform;
6) With pole slice trimming mechanism;
7) With tension buffer mechanism;
8) It has the function of dust and iron removal by pole brush;
9) With front tension stretching and rear tension stretching devices;
10) The hydraulic system adjusts the lift of the oil cylinder through the human-computer interface touch screen to drive the lift of the roll;
11) Adjust and change the pressure of the roll cylinder through the man-machine interface, control the constant pressure, and the man-machine interface displays the actual pressure;
12) The up and down movement value of the roll is displayed on the man-machine interface screen;
13) The roll surface is plated with hard chromium, and the thickness of chromium layer after grinding is ≥ 120um;
14) Rolling speed ≥ 50m/min;
15) Roll removal device;
16) Laser on-line thickness measurement function;
