Slot die coater adjusting device for controlling distance between upper discharge port and lower discharge port of slot die coater, and electrode active material coating system including same

A slot die coater adjusting device, comprising:

• pressing block assemblies respectively provided to both longitudinal sides of a slot die coater and fixed to an upper die of the slot die coater;
• a linear motion (LM) guide disposed at a lower portion of the pressing block assembly and connected to the pressing block assembly to guide a movement of the pressing block assembly;
• a servo motor configured to give a power for moving the LM guide;
• and
• a reducer connected between the servo motor and the LM guide,
• wherein the slot die coater adjusting device is configured to adjust the slot die coater including a lower die having a lower discharge hole for discharging a first active material slurry and the upper die having an upper discharge hole for discharging a second active material slurry, to adjust a distance between the lower discharge hole and the upper discharge hole by allowing the upper die to move,
• wherein the LM guide includes:
• a guide frame;
• a ball screw installed inside the guide frame and connected to the reducer to receive the power therefrom;
• and
• a movable block fastened with the ball screw to linearly move in a front and rear direction of the slot die coater according to a rotation of the ball screw.
