The crank (9) drives the worm (8) to rotate, the worm (8) drives the worm wheel (7) to rotate, and the worm wheel (7) drives the movable frame (3) to move. The distance between the lower pressure roller (2) and the upper pressure roller (4) is adjusted with reference to the value displayed on the micrometer (11); 3) After the movable frame (3) is moved and adjusted, the crank (9) is removed from the driving groove (801), and the ring sleeve (10) is rotated in the opposite direction to separate the protrusion (1101) from the innermost end of the L-shaped limit groove (1001), and the dial gauge (11) can be taken out of the sleeve (301) and stored separately; 4) When the copper sheet passes through the gap between the lower pressing roller (2) and the upper pressing roller (4), the motor drives the lower pressing roller (2) to rotate, the lower pressing roller (2) drives the pinion A (5) to rotate, the pinion A (5) drives the pinion B (6) to rotate, and the pinion B (6) drives the upper pressing roller (4) to rotate. The lower pressing roller (2) and the upper pressing roller (4) roll the two sides of the copper sheet to gradually thin the copper sheet, thereby realizing the copper foil calendering process. At this point, the operation of the device is completed.
