Automatic Press Rolling Machine/Calender Machine For Lithium Battery Electrode Manufacturing



A.Equipment functions:

1. This set of equipment is connected by a standard roller aligning machine, which is suitable for the high-speed tablet pressing process of continuous pole coating. This set of equipment is mainly composed of a single station unwinding part, a front and rear tension stretching part, an oil pressure roller aligning host part, an online thickness measurement system, and a single station rewinding part.

1) This machine has a mouth shaped integrally cast 45# steel frame, large slider structure, large bearing capacity, small deformation, large rolling force and high rolling speed;

2) By using the constant pressure limited gap rolling method, the battery pole pieces with longitudinal blank and continuous coating can be rolled continuously;

3) Scraper device with roller surface cleaning mechanism;

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;
